Non-negligible amounts of Distributed Generating Units (DGUs) are already connected to power systems, predominantly to medium- and low-voltage networks. The interaction between distribution and transmission systems is gaining the attention of system operators. Given the high controlability of DGUs, the active distribution networks can potentially support the transmission system during emergency situations. Previously proposed voltage emergency controls involving distribution network assets focused on preserving the transmission system integrity, even if it implies affecting the distribution system operation (intrusive schemes). More attention needs to be devoted to supporting transmission voltages, while preserving the distribution network operation (non-intrusive schemes). This paper introduces a new adaptive and non-intrusive voltage emergency control scheme based on the synchronization of DGUs and the load tap changer of the corresponding distribution transformer. The conclusions are derived from time-domain simulations using an extended version of the IEEE Nordic test system for voltage stability assessment. [less ▲]

La présente contribution entend mener l’étude des promesses communicationnelles portées par les dispositifs médiatiques requérant la participation des chercheurs voire, dans certains cas, du grand public, en prenant pour terrain d’analyse deux sites agissant sur des plans distincts : l’un opérant sur une scène d’énonciation scientifique, Hypotheses.org, l’autre sur une scène d’énonciation journalistique, The Conversation. Ces promesses seront lues suivant une approche narrative et l’on précisera le rôle joué par la participation dans le récit de chaque organisation médiatique : on montrera ainsi comment la participation contribue à charger de valeur la communication des savoirs scientifiques dans ces dispositifs médiatiques. Enfin, nous questionnerons l’adhésion à l’impératif de transparence dont ces promesses se font l’écho, sous des modalités diverses, et la manière dont il influence la circulation sociale des savoirs.

Background: Odanacatib, a cathepsin K inhibitor, reduces bone resorption while maintaining bone formation. Previous work has shown that odanacatib increases bone mineral density in postmenopausal women with low bone mass. We aimed to investigate the efficacy and safety of odanacatib to reduce fracture risk in postmenopausal women with osteoporosis. Methods: The Long-term Odanacatib Fracture Trial (LOFT) was a multicentre, randomised, double-blind, placebocontrolled, event-driven study at 388 outpatient clinics in 40 countries. Eligible participants were women aged at least 65 years who were postmenopausal for 5 years or more, with a femoral neck or total hip bone mineral density T-score between –2·5 and –4·0 if no previous radiographic vertebral fracture, or between –1·5 and –4·0 with a previous vertebral fracture. Women with a previous hip fracture, more than one vertebral fracture, or a T-score of less than –4·0 at the total hip or femoral neck were not eligible unless they were unable or unwilling to use approved osteoporosis treatment. Participants were randomly assigned (1:1) to either oral odanacatib (50 mg once per week) or matching placebo. Randomisation was done using an interactive voice recognition system after stratification for previous radiographic vertebral fracture, and treatment was masked to study participants, investigators and their staff, and sponsor personnel. If the study completed before 5 years of double-blind treatment, consenting participants could enrol in a double-blind extension study (LOFT Extension), continuing their original treatment assignment for up to 5 years from randomisation. Primary endpoints were incidence of vertebral fractures as assessed using radiographs collected at baseline, 6 and 12 months, yearly, and at final study visit in participants for whom evaluable radiograph images were available at baseline and at least one other timepoint, and hip and non-vertebral fractures adjudicated as being a result of osteoporosis as assessed by clinical history and radiograph. Safety was assessed in participants who received at least one dose of study drug. The adjudicated cardiovascular safety endpoints were a composite of cardiovascular death, myocardial infarction, or stroke, and new-onset atrial fibrillation or flutter. Individual cardiovascular endpoints and death were also assessed. LOFT and LOFT Extension are registered with ClinicalTrials.gov (number NCT00529373) and the European Clinical Trials Database (EudraCT number 2007-002693-66). Findings: Between Sept 14, 2007, and Nov 17, 2009, we randomly assigned 16 071 evaluable patients to treatment: 8043 to odanacatib and 8028 to placebo. After a median follow-up of 36·5 months (IQR 34·43–40·15) 4297 women assigned to odanacatib and 3960 assigned to placebo enrolled in LOFT Extension (total median follow-up 47·6 months, IQR 35·45–60·06). In LOFT, cumulative incidence of primary outcomes for odanacatib versus placebo were: radiographic vertebral fractures 3·7% (251/6770) versus 7·8% (542/6910), hazard ratio (HR) 0·46, 95% CI 0·40–0·53; hip fractures 0·8% (65/8043) versus 1·6% (125/8028), 0·53, 0·39–0·71; non-vertebral fractures 5·1% (412/8043) versus 6·7% (541/8028), 0·77, 0·68–0·87; all p<0·0001. Combined results from LOFT plus LOFT Extension for cumulative incidence of primary outcomes for odanacatib versus placebo were: radiographic vertebral fractures 4·9% (341/6909) versus 9·6% (675/7011), HR 0·48, 95% CI 0·42–0·55; hip fractures 1·1% (86/8043) versus 2·0% (162/8028), 0·52, 0·40–0·67; non-vertebral fractures 6·4% (512/8043) versus 8·4% (675/8028), 0·74, 0·66–0·83; all p<0·0001. In LOFT, the composite cardiovascular endpoint of cardiovascular death, myocardial infarction, or stroke occurred in 273 (3·4%) of 8043 patients in the odanacatib group versus 245 (3·1%) of 8028 in the placebo group (HR 1·12, 95% CI 0·95–1·34; p=0·18). New-onset atrial fibrillation or flutter occurred in 112 (1·4%) of 8043 patients in the odanacatib group versus 96 (1·2%) of 8028 in the placebo group (HR 1·18, 0·90–1·55; p=0·24). Odanacatib was associated with an increased risk of stroke (1·7% [136/8043] vs 1·3% [104/8028], HR 1·32, 1·02–1·70; p=0·034), but not myocardial infarction (0·7% [60/8043] vs 0·9% [74/8028], HR 0·82, 0·58–1·15; p=0·26). The HR for all-cause mortality was 1·13 (5·0% [401/8043] vs 4·4% [356/8028], 0·98–1·30; p=0·10).When data from LOFT Extension were included, the composite of cardiovascular death, myocardial infarction, or stroke occurred in significantly more patients in the odanacatib group than in the placebo group (401 [5·0%] of 8043 vs 343 [4·3%] of 8028, HR 1·17, 1·02–1·36; p=0·029, as did stroke (2·3% [187/8043] vs 1·7% [137/8028], HR 1·37, 1·10–1·71; p=0·0051). Interpretation: Odanacatib reduced the risk of fracture, but was associated with an increased risk of cardiovascular events, specifically stroke, in postmenopausal women with osteoporosis. Based on the overall balance between benefit and risk, the study’s sponsor decided that they would no longer pursue development of odanacatib for treatment of osteoporosis. [less ▲]

The digital revolution sets a milestone in the progressive miniaturization of working devices and in the underlying advent of molecular machines. Foldamers involving mechanically entangled components with modular secondary structures are among the most promising designs for molecular switch-based applications. Characterizing the nature and dynamics of their intramolecular network following the application of a stimulus is the key to their performance. Here, we use non-dissociative electron transfers as a reductive stimulus in the gas phase and probe the consecutive co-conformational transitions of a donor-acceptor oligorotaxane foldamer using electrospray mass spectrometry interfaced with ion mobility and infrared ion spectroscopy. The comparison of collision cross section distributions for analogous closed-shell and radical molecular ions sheds light on their respective formation energetics while variations in their respective infrared absorption bands evidence different intramolecular organizations as the foldamer gets compact. These differences are compatible with the advent of radical-pairing interactions. [less ▲]

Dans l’une de ses conversations avec Joachim Gasquet sur le sens de sa peinture (et de la peinture en général), Cézanne aborde de front la conception qu’il se fait de la couleur, dans son rapport à la profondeur picturale et de son articulation à la surface : « La nature n'est pas en surface ; elle est en profondeur. Les couleurs sont l'expression, à cette surface, de cette profondeur. Elles montent des racines du monde ». Cet « organisme de couleurs » que constitue le monde est transcrit dans la peinture de Cézanne par une dynamique symbiotique de la couleur et du dessin, de la ligne et du pan. La couleur restitue, par sa masse, son surgissement, son homogénéité, presque sa viscosité, la véritable chaire perceptive du monde ; une vision qui tient à distance la perspective géométrique, photographique, cinématographique fondée sur la transparence et qui repose, comme le signale Merleau-Ponty, sur la « réversibilité des dimensions » (surface-profondeur) et l’entrelacement des choses. C’est cette épaisseur du visible rendu par la couleur que l’économie de l’image numérique nous permet de redécouvrir, moins dans le registre de la « tactilité » de l’image et la picturalité du pixel, que par l’intégration, entre le support et l’image (parfois indiscernables dans le régime optique), d’un « corps » algorithmique qui règle l’actualisation du visible. Certains défauts techniques du dispositif numérique, aujourd’hui élevés au rang de pratique artistique, permettent de révéler cette matrice qui utilise alors la couleur et la coulure comme mode de visibilité. C’est le cas du Datamoshing, technique de composition numérique qui revisite tout en la radicalisant la pratique de l’incrustation vidéo. Basée sur la perturbation volontaire d’éléments de la matrice, cette technique transforme les couleurs en une forme malléable et fluide révélant ainsi leur double nature spatiale : elles sont à la fois dans l’espace de l’image et l’espace de l’image lui-même. Ces expériences de défigurations d’images s’inscrivent dans le registre des « aberrations chromatiques » dont nous proposons ici une rapide généalogie avant d’interroger la couleur digitale dans ses spécificités.

We study dynamical notions lying between U-frequent hypercyclicity and reiterative hypercyclicity by investigating weighted upper densities between the unweighted upper density and the upper Banach density. While chaos implies reiterative hypercyclicity, we show that chaos does not imply U-frequent hypercyclicity with respect to a weighted upper density. Moreover, we show that if T is U-frequently hypercyclic (resp. reiteratively hypercyclic) then the n-fold product of T is still U-frequently hypercyclic (resp. reiteratively hypercyclic) and that this implication is also satisfied for each of the considered U-frequent hypercyclicity notions.

Remembering everyday events typically takes less time than the actual duration of the retrieved episodes, a phenomenon that has been referred to as the temporal compression of events in episodic memory. Here, we review recent studies that have shed light on how this compression mechanism operates. The evidence suggests that the continuous flow of experience is not represented as such in episodic memory. Instead, the unfolding of events is recalled as a succession of moments or slices of past experience that includes temporal discontinuities—portions of past experience are omitted when remembering. Consequently, the rate of event compression is not constant but depends on the density of recalled segments of past experience. [less ▲]

La démocratie reste un thème chéri par la philosophie politique contemporaine, pour l’écart entre ses théories et ses pratiques, pour la distance critique que ses théories offrent vis-à-vis des régimes démocratiques et de leur évolution, mais aussi parce qu’elle est un objet perpétuel de dissensus entre philosophes, au sujet duquel toute prétention à la véridiction est suspendue à sa réalisation pratique. À ce titre, la transmission de la volonté démocratique est un topos houleux de la philosophie politique contemporaine. Cette question catalyse les concepts pivots des philosophies politiques, la leur poser permet de mieux saisir les enjeux rivaux derrière une terminologie commune à plusieurs auteurs. C’est dans cette démarche que je vous propose d’examiner en miroir les philosophies de Cornélius Castoriadis et de Jacques Rancière. De plus en plus nombreux, des commentateurs rapprochent leurs pensées , qui peuvent s’appuyer sur plusieurs points communs : un attachement au concept de démocratie brandit contre les régimes parlementaires, une opposition contemporaine (quoique depuis des héritages différents) aux thèses défendues par Althusser, et une proximité de sources d’inspirations : la philosophie, le marxisme, et la psychanalyse. Partant de la manière dont cette proximité s’exprime dans la disjonction que chacun opère entre démocratie et science, je tenterai de discerner comment les inflexions qu’ils impriment aux concepts de volonté et d’égalité sous la guise des enjeux de la transmission dessinent des horizons politiques distincts, et dénotent des compréhensions antithétiques – mais indécidables dans la théorie – de ce que peut être la démocratie.

Background. Unilateral vocal fold paralysis (UVFP) often leads to significant morbidity that may include dysphonia, swallowing problems and aspiration. The best timing for medialization procedures is still controversial. Published data suggest that early intracordal injection positively affects long-term outcomes. Objectives. To critically review current literature in order to determine if early treatment of acute UVFP influences clinical outcomes of the patients. Type of Review. Nonsystematic literature review. Methods. A literature review was performed, using the Pubmed database. All relevant articles published in English addressing the effect of early treatment in acute unilateral focal fold paralysis were analyzed. Twenty-six articles were included due to their scientific interest. Results. Published literature suggests that early intracordal injection in patients with UVFP reduces pulmonary infections, hospital length of stay and improves voice parameters. Also, patients who receive early intracordal injection seem to be less likely to undergo subsequent medialization thyroplasty. Conclusions. Early intracordal injection should be offered to patients with newly diagnosed UVFP since it promotes a satisfactory position of the vocal fold and seems to improve clinical outcomes. More investigation, with long-term follow up data and treatment randomization, is necessary to develop clinical consensus for these patients. [less ▲]

Le monde des études littéraires a vu se développer, au cours de ces dernières années, une théorie des textes possibles qui confronte la réception traditionnelle des œuvres (c’est-à-dire la façon dont leur lecture se concrétise la plupart du temps et le commentaire qu’on en livre habituellement) à une réinvention de leur signification, tirant parti des impensés de la fiction, des non-dits, des interactions interrompues, des blancs, des inférences labiles et autres zones creuses du récit qui offrent des prises pour une renégociation herméneutique. À côté des réinventions herméneutiques des œuvres classiques, de l’approche génétique et du fantasme programmatique autour des productions perdues, la critique des textes possibles aurait tout à gagner à explorer un continent fictionnel, fructueux en termes d’œuvres en puissance et qui recèle d’indications sur l’évaluation des modes et tendances d’une époque émanant des représentations des écrivains eux-mêmes : les œuvres imaginaires qui n’existent qu’en tant qu’elles sont inscrites dans d’autres œuvres, qui en esquissent les contours, les présentent voire les citent.

If these joint publications do not constitute a remediation in the strict sense of the term, where a document would be re-stated within a digital device and would bear the marks linked to this new context of enunciation (Colas-Blaise 2018), the textual variations linked to the enunciation in both of these devices would be relevant with regard to the communication project they support. Mobilizing the heuristic approach of communication spaces (Odin 2011), we will try to identify them and propose a reading of these digital devices by focusing on their temporality as a source of media variation (Bonaccorsi and Flon 2014).

Spinal muscular atrophy (SMA) is a rare and devastating disease. New disease- modifying treatments have recently been approved and early treatment has been related to a better outcome. In this context, several newborn screening (NBS) programs have been implemented. The aim of the study was to obtain a global overview on the current situation and perspectives on SMA NBS. We conducted a survey and contacted experts from 152 countries, from which we gathered 87 responses. We identified 9 SMA NBS programs that have so far detected 288 newborns with SMA out of 3,674,277 newborns screened. Funding, screening methods, organisation, and consent process were variable between SMA NBS programs. Many respondents pointed the lack of cost/benefit data as a major obstacle to SMA NBS implementation. In the next four years, our data suggest a 24 % coverage of newborns from countries where a disease-modifying drug is available and 8,5 % coverage in countries with no diseases-modifying drugs. The annual proportion of newborns to be screened in the coming years is expected to increase steadily. The experts expressed a strong need for the implementation of SMA NBS as means to improve care for patients with SMA. [less ▲]

Voice feminization for transgender women remains a challenge. The fundamental frequency of the voice (fo) is one of the main parameters contributing to the perception of gender. One of the aims of voice therapy is to help transgender women acquire a new vocal motor behavior to increase their fo. We hypothesized that ambulatory biofeedback could help extend the new vocal behavior to daily life. This prospective case study assessed the impact of two weeks of ambulatory vibrotactile biofeedback (VTBF) applied to one transgender woman, following two weeks of voice therapy (three 60-minute sessions). The VTBF was activated when the participant’s voice was lower than 150 Hz for more than 500 ms and was accompanied by two 60-minute counseling sessions. The results showed that mean fo monitored in daily activities tended to increase following the two weeks of voice therapy (Δ = 8 Hz or 1 semitone) and then increased significantly immediately after the two weeks of VTBF (Δ = 13 Hz or 1.5 semitones). The increase in mean fo from day to day and the decrease in the activation percentage from the first to the second week of VTBF (Δ = 6%) indicated a gradual integration of the motor behavior, making it possible to achieve the targeted female frequency. The results suggest that ambulatory VTBF helped the participant to generalize the techniques acquired during the voice therapy sessions to real-life communication situations. These results are promising for therapeutic programs that integrate tools that can be used outside the clinical context. [less ▲]

We aimed to evaluate the effect of different grazing management strategies on carcass characteristics traits, meat quality and CH4 intensity and yield of lambs grazing Italian ryegrass pastures in Southern Brazil. A grazing trial was performed (2014 and 2015) in a randomized complete block design with two grazing management targets and four replicates. Treatments were traditional rotational stocking (RT), with pre- and post-grazing sward heights of 25 and 5 cm, respectively, and ‘Rotatinuous’ stocking (RN), with pre- and post-grazing sward heights of 18 and 11 cm, respectively. Castrated crossbred Texel and Polwarth lambs were used. Results indicated that diet cost per kg of dry matter (p = 0.001) and per hectare (p < 0.001) were lower for RN than for RT treatment. Final live weight (p = 0.022) and hot and cold carcass weight (p = 0.006) were greater for the RN treatment. All commercial cuts were greater for RN than for RT treatment. The RN treatment presented greater (p < 0.001) production of carcass, edible food and crude protein. Feed efficiency and feed cost conversion were better for RN than for RT treatment. CH4 intensity per kg of carcass, edible food and crude protein gain were 2.6, 2.7 and 2.1 times lower (p < 0.001) for RN. Moreover, CH4 yield was lower (p = 0.014) for RN than for RT treatment, with an average of 7.6 and 8.3% of the gross energy intake, respectively. We conclude that the ‘Rotatinuous’ stocking results in a greater carcass production, carcass quality and lower diet cost, and CH4 intensity and yield of grazing lambs. Adopting this grazing management strategy could enhance both lamb production and mitigation of CH4 intensity and yield in grazing ecosystems, which could be considered a good example of climate-smart livestock production.

This study examines the contribution of the psychological contract (PC) framework to the understanding of ethnic minority employees’ employment relationships. First, it tests the generalizability of PC types (transactional, relational, and balanced) observed in the general population to ethnic minority employees. Then, to further address the unique needs and motivators of minority employees, this study considers diversity-related PCs. It adopts social exchange theory to explain how transactional, relational, balanced, and diversity-related PC breaches predict organizational citizenship behavior (OCB). Moreover, it draws insights from social identity theory and examines the mediating role of organizational identification in the relationship between types of PC breach and OCB. Data from 361 Turkish employees working as ethnic minorities in Belgium indicate that relational and diversity-related PC breaches predict OCB partially via organizational identification while transactional and balanced PC breaches directly affect OCB.

An increasing amount of research has examined the management of competing logics, and possible tensions arising between them, within “hybrid organizations”. However, the ways in which the relationships of hybrids with other organizations shape the conciliation of these logics and tensions has received limited attention so far. In this theoretical paper, we examine how hybrid organizations deal with interorganizational collaboration, in particular whether and how their hybridity can be maintained when they partner with “dominant-logic organizations”. Drawing on empirical literature on social enterprise-corporate collaborations, we develop a framework and several propositions on how competing logics and their balancing within hybrid organizations may be affected by interactions with organizations underpinned by one dominant logic. We suggest that influences will mostly depend on the type of collaboration pursued. A collaboration based on a lower level of engagement and interaction between the two partners is likely to give precedence to one logic over the other, reducing inter-logic tensions but possibly compromising organizational hybridity. By contrast, a collaboration featuring numerous interactions and mission compatibility may facilitate sustained hybridity if tensions are acknowledged and managed. Our propositions contribute to the literatures on hybrid organizations, interorganizational collaboration, and social enterprise. [less ▲]

Objectives: To evaluate patients’ preferences for sarcopenia outcomes. Design: Discrete-choice experiment (DCE) Setting and Participants: Community-dwelling individuals older than 65 years suffering from sarcopenia recruited in Belgium, France, Germany, Italy, Spain, and Switzerland, who visited the clinic and were cognitively able to understand and fill out the survey. Methods: In the DCE survey, participants were repetitively asked to choose which one of the 2 patients suffering from sarcopenia deserves treatment the most. The 2 patients presented different levels of risk for 5 preselected sarcopenia outcomes: quality of life, mobility, domestic activities, fatigue, and falls. The DCE included 12 choice sets. Mixed logit panel model was used to estimate patients’ preferences and latent class model was conducted to identify profiles of responses. Results: Atotal of 216 sarcopenic personswere included for the analysis (68%women;mean age 78 years). All 5 preselected sarcopenia outcomes were shown to be significant. Overall, the most important sarcopenia outcome was mobility (30%), followed by the ability to manage domestic activities (22%), the risk of falls (18%), fatigue (17%), and quality of life (14%). The latent class model identified 2 classes of respondents. In the first class (probability of 56%), participants valued mobility the most (42%), followed by the ability to manage domestic activities (23%) and risk of falls (17%). In the second class, fatiguewas the most important outcome (27%) followed by domestic activities (19%) and risk of falls (19%). No statistically significant associations between the latent classes and sociodemographic characteristics were found. Conclusions and Implications: This study suggests that all 5 preselected outcomes were important for sarcopenic older individuals. Overall, the most important outcomes were mobility and the ability to manage domestic activities, although variations in preferenceswere observed between respondents. This could help in incorporating patient preferences when designing appropriate solutions for individuals with sarcopenia. [less ▲]

The purpose of this article is to study sense of parental competence in parents who experienced abuse in childhood. Many studies have shown that the kind of abuse (physical, emotional, sexual, neglect) that the parent experienced in childhood and the co-occurrence of several types of abuse affect the sense of parental competence. In particular, we focused on the difference between sexual abuse and other kinds of abuse. The instruments used to collect data were the French versions of the Childhood Trauma Questionnaire, which assesses abuse, and the Parenting Sense of Competence Scale, which assesses efficacy and satisfaction. These questionnaires were designed to quantitatively evaluate the kind of abuse experienced during childhood and the sense of parental competence. We collected 828 valid protocols. The statistical analyses show that sense of parental competence is lower in parents who were abused during their childhood than in those who were not. More specifically, our results show that these parents feel less satisfaction, one of the two components of the sense of parental competence. [less ▲]

Multivariate analyses on formulation and mechanical behavior of nonwoven and nonoriented natural fibers reinforced thermoplastic starch (TPS) composites were performed. Glycerol and water were considered as TPS plasticizers. Fibers composition (i.e., cellulose, hemicellulose, lignin), fibers morphology (fibers length), starch composition (i.e., amylose/amylopectin ratio) as well as the processing conditions (i.e., temperature, rotor speed, relative humidity during aging) were evaluated for their ability to affect the elastic modulus, tensile strength, and elongation at break of the final materials. Multivariate linear regressions were computed to unveil the importance of each variable on the mechanical behavior. Fibers composition impacted the most the models: cellulose maximization improved the elastic modulus and tensile strength while lignin reduced the elastic modulus and hemicellulose decreased the tensile strength. TPS plasticizers, temperature, and rotor speed of the process were negatively impacting the elastic modulus but in a lesser extent than the fiber composition. Within the range of the created database, the selected variables and attributed coefficients were permitted to explain the variability. The produced models revealed that complex and yet uninvestigated interactions are to be considered within TPS-based biocomposites. Therefore, this work discusses and suggests a “must-have” list of variables for comparable analyses of new TPS-based biocomposites using natural fibers as reinforcement. [less ▲]

Regional connectivity-based parcellation (rCBP) is a widely used procedure for investigating the structural and functional differentiation within a region of interest (ROI) based on its long-range connectivity. No standardized software or guidelines currently exist for applying rCBP, making the method only accessible to those who develop their own tools. As such, there exists a discrepancy between the laboratories applying the procedure each with their own software solutions, making it difficult to compare and interpret the results. Here, we outline an rCBP procedure accompanied by an open source software package called CBPtools. CBPtools is a Python (version 3.5+) package that allows users to run an extensively evaluated rCBP analysis workflow on a given ROI. It currently supports two modalities: resting-state functional connectivity and structural connectivity based on diffusion-weighted imaging, along with support for custom connectivity matrices. Analysis parameters are customizable and the workflow can be scaled to a large number of subjects using a parallel processing environment. Parcellation results with corresponding validity metrics are provided as textual and graphical output. Thus, CBPtools provides a simple plug-and-play, yet customizable way to conduct rCBP analyses. By providing an open-source software we hope to promote reproducible and comparable rCBP analyses and, importantly, make the rCBP procedure readily available. Here, we demonstrate the utility of CBPtools using a voluminous data set on an average compute-cluster infrastructure by performing rCBP on three ROIs prominently featured in parcellation literature.

AIMS: The aim of this study was to evaluate the two-year outcomes of the One Tooth-One Time (1T1T) completely digital workflow, allowing the immediate loading of a single implant in the posterior region with a final CAD-CAM crown made of a polymer-infiltrated ceramic network (PICN). MATERIALS AND METHODS: A series of 10 implants were placed, and an intra-oral scan was taken after the surgery. A final screw-retained PICN crown was manufactured chair-side and placed the same day in full occlusion. Marginal peri-implant bone changes and soft-tissue health were evaluated, as well as restoration performance using World Dental Federation criteria and Pink and White Esthetic Scores. Patient-related outcome measures (PROMs) and time consumption data were collected. RESULTS: After two years, the implant survival rate was 100%. The debonding of one crown from its Titanium Base led to a 90% prosthodontic survival rate and the remaining crowns were all considered successful. The mean marginal peri-implant bone changes yielded 0.87 (SD: 0.96) and 0.55 (SD: 0.53) mm after one and two years, respectively. Mild or no inflammation of peri-implant soft tissue was observed in most implants. The overall treatment time reached 175 min and PROMs displayed high patient satisfaction. CONCLUSIONS: This study constitutes the first report considering immediate loading of a single implant in the posterior region with a final crown in occlusion. In this case-series, the two-year outcomes of the 1T1T protocol seem rather promising and fulfil patient expectations. However, those preliminary results need to be confirmed by randomized control trials and patient selection is probably a key factor in this procedure success. [less ▲]

Je donnerai différents arguments en analysant ces débats (historiques, méthodologiques et cliniques) afin de proposer une lecture singulière des pathologies de la liberté et de voir comment cette lecture s’inscrit dans le champ psychopathologique. L’objectif de ma contribution sera de rencontrer le vécu en première personne du sujet psychotique qui se retrouve mal dans la qualification de son existence comme étant privée de liberté. Comme le titre de cette étude l’annonce, la thèse que je défends est de considérer que l’interrogation des pathologies de la liberté conduit également à interroger son corollaire, la dimension inéluctablement libre inhérente aux personnes affectées de psychopathologies. Ce décalage, que nous permettra d’entrevoir Lacan, nous mènera à interroger la dimension adaptative de l’expérience psychopathologique et, dans la continuité de Canguilhem, à considérer la pathologie comme la création de normes inédites (généralement inaccessibles à autrui).

There appears to be no consensus as yet on the meaning of the term "world" in "world literature". Over the last few years, "world" has indeed been the object of a multitude of responses and readings, which markedly vary according to researchers’ academic backgrounds and theoretical vantage points. How then is the "world" of "world literature" to be apprehended? Combining linguistics-informed and close-reading methods, the present essay seeks to shed light on a notional issue that has especially divided world and postcolonial literary scholars in recent times. More precisely, it will be argued that "world" in the phrase "world literature" has begun to undergo a linguistic process of re-semanticization, whereby this lexical item has come to encode, and be imbued with, values central to the postcolonial agenda – thus providing the postcolonial cause with fresh impetus in the twenty-first century.

Motivated by the problem of bounding the number of iterations of the Simplex algorithm we investigate the possible lengths of monotone paths followed inside the oriented graphs of polyhedra (oriented by the objective function). We consider both the shortest and the longest monotone paths and estimate the monotone diameter and height of polyhedra. Our analysis applies to transportation polytopes, matroid polytopes, matching polytopes, shortest-path polytopes, and the TSP, among others. We begin by showing that combinatorial cubes have monotone diameter and Bland simplex height upper bounded by their dimension and that in fact all monotone paths of zonotopes are no larger than the number of edge directions of the zonotope. We later use this to show that several polytopes have polynomial-size monotone diameter. In contrast, we show that for many well-known combinatorial polytopes, the height is at least exponential. Surprisingly, for some famous pivot rules, e.g., greatest improvement and steepest edge, these same polytopes have polynomial-size simplex paths. [less ▲]

The direct imaging of rocky exoplanets is one of the major science goals for upcoming large telescopes. The contrast requirement for imaging such planets is challenging. However, the mid-IR (InfraRed) regime provides the optimum contrast to directly detect the thermal signatures of exoplanets in our solar neighbourhood. We aim to exploit novel fast chopping techniques newly developed for astronomy with the aid of adaptive optics to look for thermal signatures of exoplanets around bright stars in the solar neighbourhood. We use the upgraded VISIR (Very Large Telescope Imager and Spectrometer for the mid-InfraRed) instrument with high contrast imaging (HCI) capability optimized for observations at 10~$\mu$m to look for exoplanets around five nearby ($d$ < 4 pc) stars. The instrument provides an improved signal-to-noise (S/N) by a factor of $\sim$4 in the N-band compared to standard VISIR for a given S/N and time. In this work we achieve a detection sensitivity of sub-mJy, which is sufficient to detect few Jupiter mass planets in nearby systems. Although no detections are made we achieve most sensitive limits within $<2''$ for all the observed targets compared to previous campaigns. For $\epsilon$ Indi A and $\epsilon$ Eri we achieve detection limits very close to the giant planets discovered by RV, with the limits on $\epsilon$ Indi A being the most sensitive to date. Our non-detection therefore supports an older age for $\epsilon$ Indi A. The results presented here show the promise for high contrast imaging and exoplanet detections in the mid-IR regime. [less ▲]

Aims: The purpose of this study was to investigate the occurrence of E. coli O157 and O26 on Belgian dairy cattle farms, the presence of virulence genes in the confirmed isolates, and the association of E. coli O26 presence with calf diarrhea. Methods and Results: In total, 233 recto-anal mucosal swabs (RAMS) were obtained from healthy and diarrheic dairy calves on three farms, each alternately visited three consecutive times. RAMS were analyzed for presence of E. coli O157 and O26, and stx1, stx2 and eae virulence genes. Overall, 19% of RAMS tested positive for E. coli O157, while 31% tested positive for E. coli O26. The majority of isolates possessed both stx and eae, denoting a high pathogenic potential to humans. While both serogroups persisted at farm level, persistence within the same animal over time appeared to be relatively rare. Interestingly, E. coli O26 was already abundantly present at a younger age compared to E. coli O157. Calf diarrhea could not be associated with presence of E. coli O26. Conclusions: Young dairy calves are important on-farm reservoirs of potentially pathogenic E. coli O157 and O26. A role of E. coli O26 in calf diarrhea could not be confirmed. Significance and Impact of Study: O157 and O26 are responsible for the majority of human STEC infections. Gaining more epidemiological information regarding their occurrence and persistence on cattle farms will contribute to a better understanding of STEC ecology and risk of human transmission. [less ▲]

Enterohemorrhagic Escherichia coli (EHEC), enteropathogenic E. coli (EPEC) and Shigatoxigenic E. coli (STEC) are carried by healthy adult cattle and even more frequently, young calves in their intestinal tract, especially at the height of the recto-anal junction. The purpose of the present study was to assess the presence of ten EHEC, EPEC and/or STEC O serotypes (O5, O26, O80, O103, O111, O118, O121, O145, O157, O165) in calves sampled by recto-anal mucosal swabs (RAMS) in three dairy farms in Belgium. A total of 233 RAMS were collected on 3 consecutive times from healthy <6-month-old Holstein-Friesian calves and submitted to a PCR targeting the eae, stx1 and stx2 genes after non-selective overnight enrichment growth. The 148 RAMS testing positive were streaked on four (semi-)selective agar media: of the 2146 colonies tested, 294 from 69 RAMS were PCR-confirmed as EHEC, EPEC or STEC. The most frequent virulotype was eae+ EPEC and the second one was stx1+stx2+ STEC while the eae+stx1+ and eae+stx1+stx2+ virulotypes were the most frequent amongst EHEC. The majority of EHEC (73%) tested positive for one of the 5 O serotypes detected (O26, O103, O111, O145, or O157) vs. 23% of EPEC and 45% of STEC. Similarly, more RAMS (73%) harbored EHEC isolates positive for those 5 serotypes, than EPEC (53%) or STEC (52%). This survey confirms that (i) healthy young dairy calves are asymptomatic carriers of EHEC and EPEC in Belgium; (ii) the carrier state rates, the virulotypes and the identified O serotypes differ between farms and in time; and (iii) a majority of EPEC belong to still unidentified O serotypes [less ▲]

In that perspective, we used an improved version of the Shockley-Queisser model including non-radiative recombination via an external parameter defined as the internal quantum efficiency. Based on predicted optimal absorber layer thicknesses, the variation of the solar cell maximal efficiency is studied as a function of the non-radiative recombination rate. Maximal efficiencies of 25.71, 19.85 and 3.10 % are reported respectively for Cu2ZnSnS4, Cu2ZnGeS4 and Cu2ZnSiS4 for vanishing non-radiative recombination rate. Using an internal quantum efficiency value providing experimentally comparable VOC values, cell efficiencies of 15.88, 14.98 and 2.66 % are reported respectively for Cu2ZnSnS4, Cu2ZnGeS4 and Cu2ZnSiS4. We confirm the suitability of Cu2ZnSnS4 in single junction solar cells, with a possible efficiency improvement of nearly 10% enabled through the reduction of the non-radiative recombination rate. In addition, Cu2ZnGeS4 appears to be an interesting candidate as top cell absorber layer for tandem approaches whereas Cu2ZnSiS4 might be interesting for transparent photovoltaic windows. [less ▲]

Aim: The aim of this case series was to evaluate the 4-year outcomes of implants placed in the aesthetic area using static computer-assisted implant surgery (s-CAIS) and restored with a one-abutment one-time (OAOT) protocol using custom-made zirconia abutments and cemented provisional crowns manufactured prior to surgery. Material and methods: Ten consecutive implants were placed in the aesthetic area. Based on a digital implant and prosthodontic planning, surgical guides were ordered and used for the preparation of definitive custom-made zirconia abutments and polymethylmethacrylate provisional crowns. Implants were placed using the s-CAIS guide, and prosthetic components were placed immediately. Implant outcomes were evaluated at the time of surgery, after 4 months and after 4 years. Results: All implants were successfully placed with s-CAIS and restored with final abutments and provisional crowns. No major prosthetic adverse events were observed. After 4 years, the implant survival rate was 100%, minor peri-implant bleeding on probing was reported, and very stable peri-implant bone levels were observed. The pink aesthetic score showed that the prosthetic components were well integrated, and the peri-implant soft tissues were stable. Conclusions: Within the limits of this case series, these results suggest that emerging digital workflows allow the manufacture of final custom-made abutments and provisional crowns prior to surgery. This individualised OAOT procedure may reduce cement-related complications and improve aesthetic outcomes by optimising soft tissue healing with prosthetic components. However, such protocols have evolved towards full digital workflows, and comparative clinical trials are needed. [less ▲]

Background: Considering the heavy economic burden of osteoporotic fractures, the limits of healthcare resources, and the recent availability of new anti-osteoporosis drugs, there is continuing interest in economic evaluation studies of osteoporosis management strategies. Objectives This study aims to (1) systematically review recent economic evaluations of drugs for osteoporosis and (2) to apply an osteoporosis-specific guideline to critically appraise them. Methods: A literature search was undertaken using PubMed, EMBASE, National Health Service Economic Evaluation database, and the Cost-Effectiveness Analysis Registry to identify original articles containing economic evaluations of anti-osteoporosis drugs, published between 1 July, 2013 and 31 December, 2019. A recent European Society for Clinical and Economic Aspects of Osteoporosis, Osteoarthritis and Musculoskeletal Diseases-International Osteoporosis Foundation (ESCEO-IOF) guideline for the conduct and reporting of economic evaluations in osteoporosis was used to assess the quality of included articles. Results: The database search retrieved 3860 records, of which 27 studies fulfilled the inclusion criteria. These studies were conducted in 15 countries; 12 active drugs were assessed, including various traditional pharmacological treatments such as bisphosphonates, raloxifene, strontium ranelate, denosumab, and teriparatide, and new agents such as abaloparatide, romosozumab, and gastro-resistant risedronate. Eight out of 12 studies that compared traditional oral bisphosphonates to other active interventions (denosumab, zoledronic acid, gastro-resistant risedronate, and teriparatide) suggested that the other active agents were generally cost-effective or dominant. Additionally, the cost-effectiveness of sequential therapy has recently been assessed and indications are that it can lead to extra health benefits (larger gains in quality-adjusted life-year). The key drivers of cost effectiveness included baseline fracture risk, drug effect on the risk of fracture, drug cost, and medication adherence/persistence. The current average score for quality assessment was 17 out of 25 (range 2–15); room for improvement was observed for most studies, which could potentially be explained by the fact that most studies were published prior to the osteoporosis-specific guideline. Greater adherence to guideline recommendations was expected for future studies. The quality of reporting was also suboptimal, especially with regard to treatment side effects, treatment effect after discontinuation, and medication adherence. Conclusions: This updated review provides an overview of recently published cost-effectiveness analyses. In comparison with a previous review, recent economic evaluations of anti-osteoporosis drugs were conducted in more countries and included more active drugs and sequential therapy as interventions/comparators. The updated economic evidence could help decision makers prioritize health interventions and the unmet/unreported quality issues indicated by the osteoporosis-specific guideline could be useful in improving the transparency, quality, and comparability of future economic evaluations in osteoporosis.

Aromatase converts androgens into estrogens in the brain of vertebrates including humans. This enzyme is also expressed in other tissues where its action may result in negative effects on human health (e.g., promotion of tumor growth). To prevent these effects, aromatase inhibitors were developed and are currently used to block human estrogen-dependent tumors. In vertebrates including quail, aromatase is expressed in a highly conserved set of interconnected brain nuclei known as the social behavior network. This network is directly implicated in the expression of a large range of social behaviors. The primary goal of this study was to characterize in Japanese quail the potential impact of brain aromatase on sexual behavior, aggressiveness and social motivation (i.e., tendency to approach and stay close to conspecifics). An additional goal was to test the feasibility and effectiveness of long-term delivery of an aromatase inhibitor directly into the third ventricle via Alzet™ osmotic minipumps using male sexual behavior as the aromatase dependent measure. We demonstrate that this mode of administration results in the strongest inhibition of both copulatory behavior and sexual motivation ever observed in this species, while other social behaviors were variably affected. Sexual motivation and the tendency to approach a group of conspecifics including females clearly seem to depend on brain aromatase, but the effects of central estrogen production on aggressive behavior and on the motivation to approach males remain less clear.

Context. Hot exozodiacal dust has been shown to be present in the innermost regions of an increasing number of main sequence stars over the past fifteen years. The origin of hot exozodiacal dust and its connection with outer dust reservoirs remains however unclear. Aims. We aim to explore the possible connection between hot exozodiacal dust and warm dust reservoirs (≥ 100 K) in asteroid belts. Methods. We use precision near-infrared interferometry with VLTI/PIONIER to search for resolved emission at H band around a selected sample of 62 nearby stars showing possible signposts of warm dust populations. Results. Our observations reveal the presence of resolved near-infrared emission around 17 out of 52 stars with sufficient data quality, four of which are shown to be due to a previously unknown stellar companion. The 13 other H-band excesses are thought to originate from the thermal emission of hot dust grains, close to their sublimation temperature. Taking into account earlier PIONIER observations, where some stars with warm dust were also observed, and after re-evaluating the warm dust content of all our PIONIER targets through spectral energy distribution modeling, we find a detection rate of 17.1(+8.1)(-4.6)% for H-band excess around main sequence stars hosting warm dust belts, which is statistically compatible with the occurrence rate of 14.6(+4.3)(-2.8)% found around stars showing no signs of warm dust. After correcting for the sensitivity loss due to partly unresolved hot disks, under the assumption that they are arranged in a thin ring around their sublimation radius, we however find tentative evidence at the 3σ level that H-band excesses around stars with outer dust reservoirs (warm or cold) could be statistically larger than H-band excesses around stars with no detectable outer dust. Conclusions. Our observations do not suggest a direct connection between warm and hot dust populations, at the sensitivity level of the considered instruments, although they bring to light a possible correlation between the level of H-band excesses and the presence of outer dust reservoirs in general.

Inhibitory control underlies the ability to inhibit inappropriate responses and involves processes that suppress motor excitability. Such motor modulatory effect has been largely described during action preparation but very little is known about the neural circuit responsible for its implementation. Here, we addressed this point by studying the degree to which the extent of preparatory suppression relates to brain morphometry. We investigated this relationship in patients suffering from severe alcohol use disorder (AUD) because this population displays an inconsistent level of preparatory suppression and major structural brain damage, making it a suitable sample to measure such link. To do so, 45 detoxified patients underwent a structural magnetic resonance imaging (MRI) and performed a transcranial magnetic stimulation (TMS) experiment, in which the degree of preparatory suppression was quantified. Besides, behavioral inhibition and trait impulsivity were evaluated in all participants. Overall, whole-brain analyses revealed that a weaker preparatory suppression was associated with a decrease in cortical thickness of a medial prefrontal cluster, encompassing parts of the anterior cingulate cortex and superior-frontal gyrus. In addition, a negative association was observed between the thickness of the supplementary area (SMA)/pre-SMA and behavioral inhibition abilities. Finally, we did not find any significant correlation between preparatory suppression, behavioral inhibition and trait impulsivity, indicating that they represent different facets of inhibitory control. Altogether, the current study provides important insight on the neural regions underlying preparatory suppression and allows highlighting that the excitability of the motor system represents a valuable read-out of upstream cognitive processes.

Background. After a period of coma, a proportion of individuals with severe brain injury remain in an altered state of consciousness before regaining partial or complete recovery. Individuals with disorders of consciousness (DOC) classically receive hydration and nutrition through an enteral feeding tube. However, the real impact of the level of consciousness on an individual’s swallowing ability remains poorly investigated. Objective. We aimed to document the incidence and characteristics of dysphagia in DOC individuals and to evaluate the link between different components of swallowing and the level of consciousness. Methods. We analyzed clinical data on the respiratory status, oral feeding and otolaryngologic examination of swallowing in DOC individuals. Univariate and multivariate logistic regression was used to analyse the association of components of swallowing and participant groups (i.e., unresponsive wakefulness syndrome [UWS] and minimally conscious state [MCS]). Results. We included 92 individuals with DOC (26 UWS and 66 MCS). Overall, 99% of the participants showed deficits in the oral and/or pharyngeal phase of swallowing. As compared with the MCS group, the UWS group more frequently had a tracheostomy (69% vs 24%), with diminished cough reflex (27% vs 54%) and no effective oral phase (0% vs 21%). Conclusion. Almost all DOC participants had severe dysphagia. Some components of swallowing (i.e., tracheostomy, cough reflex and efficacy of the oral phase of swallowing) were related to consciousness. In particular, no UWS participant had an efficient oral phase, which suggests that its presence may be a sign of consciousness. In addition, no UWS participant could be fed entirely orally, whereas no MCS participant orally received ordinary food. Our study also confirms that objective swallowing assessment can be successfully completed in DOC individuals and that specific care is needed to treat severe dysphagia in DOC. [less ▲]

This article investigates how policy narratives developed by proponents and opponents of infrastructure megaprojects generate controversies that affect the megaproject implementation. Drawing evidence from the Lyon-Turin high-speed railway, we argue that megaproject implementation is a complex public management endeavour which can hardly be considered a rational, straightforward process. It is rather a non-linear process involving stakeholders with divergent interests and logics of action engaging in a battle over competing narratives to influence implementation outcomes. Institutional settings opened to opponents’ voice in megaproject decision-making facilitate and streamline the resolution of controversies, whereas difficult and conflictual conditions emerge in the opposite case.

Pedophilia is a disorder of public concern because of its association with child sexual offense and recidivism. Previous neuroimaging studies of potential brain abnormalities underlying pedophilic behavior, either in idiopathic or acquired (i.e., emerging following brain damages) pedophilia, led to inconsistent results. This study sought to explore the neural underpinnings of pedophilic behavior and to determine the extent to which brain alterations may be related to distinct psychopathological features in pedophilia. To this aim, we run a coordinate based meta-analysis on previously published papers reporting whole brain analysis and a lesion network analysis, using brain lesions as seeds in a resting state connectivity analysis. The behavioral profiling approach was applied to link identified regions with the corresponding psychological processes. While no consistent neuroanatomical alterations were identified in idiopathic pedophilia, the current results support that all the lesions causing acquired pedophilia are localized within a shared resting state network that included posterior midlines structures, right inferior temporal gyrus and bilateral orbitofrontal cortex. These regions are associated with action inhibition and social cognition, abilities that are consistently and severely impaired in acquired pedophiles. This study suggests that idiopathic and acquired pedophilia may be two distinct disorders, in line with their distinctive clinical features, including age of onset, reversibility and modus operandi. Understanding the neurobiological underpinnings of pedophilic behavior may contribute to a more comprehensive characterization of these individuals on a clinical ground, a pivotal step forward for the development of more efficient therapeutic rehabilitation strategies.

This paper advocates for a progressive rethinking of the day-ahead/intra-day power system security management practice in the low-carbon energy transition era. As a starting point, the need for multi-TSO coordination in order to efficiently exploit the value of grid flexibility towards operating the low-carbon, multi-area power system securely and economically is established. On this basis, the core proposal of this paper is the adoption of a new approach to day-ahead/intra-day multi-area power system security management, inspired from the principles of cooperative game theory. The proposed approach relies on counterfactual analysis to evaluate the (positive and/or negative) impact of each distinctive control-area to the common security of the multi-area system, thus providing clear economic incentives to achieve the required coordination. This proposal is not a marginal approach and notably facilitates the integration of more detailed physical modeling (including the non-convexities of the power system) in the inter-TSO settlement of the multi-area interconnected system security management cost. The proposed framework allows some level of subsidiarity and the definition of hedging products to cover ex-post costs. Further from the blueprint of the proposed approach, the paper discusses prominent research and development pathways in order to progressively put such vision into practice. [less ▲]

Résumé: Dans le domaine de la santé, la réalité virtuelle (RV) représente une alternative à l’exposition dans le monde réel (in vivo). Elle permet de vivre des situations proches de la réalité, dans le but de développer, d’entrainer, ou de rééduquer des compétences spécifiques dans un environnement contrôlé, en présence du clinicien. La RV est une technologie permettant d’immerger un utilisateur (e.g. un enseignant) dans un environnement en trois dimensions recréé artificiellement (e.g. une salle de classe virtuelle) afin d’y vivre une expérience proche de la réalité (e.g. donner une leçon aux élèves). Cet article présente une synthèse de nos recherches sur l’apport de la RV dans l’apprentissage de comportements vocaux efficaces. Nous évaluons l’applicabilité et l’efficacité d’une salle de classe virtuelle pour l’entrainement des compétences vocales des enseignants. Suite au développement d’une salle de classe virtuelle composée de 16 élèves animés et de bruits typiques d’école, une étude de validation a été menée sur 30 enseignantes. Les résultats suggèrent que cet environnement virtuel représente un outil écologiquement valide et utilisable pour exercer les compétences vocales : une fois immergés dans la classe virtuelle, les enseignants adoptent les adaptations vocales spécifiques aux situations d’enseignement. Une seconde étude a évalué l’efficacité d’un programme d’entrainement utilisant la RV pour l’apprentissage de compétences de communication en environnement bruyant chez des futurs enseignants. Les résultats préliminaires montrent que des simulations virtuelles de situations d’enseignement favorisent l’amélioration du sentiment d’efficacité personnelle de communication en environnement bruyant. La RV représente un outil prometteur, offrant un certain potentiel en termes d’applications puisque l’environnement virtuel peut servir non seulement aux enseignants sur le terrain mais également aux futurs enseignants, dans l’optique de les entraîner (prévention) et aux enseignants en souffrance (rééducation de patients dysphoniques). Abstract: In the field of health care, virtual reality (VR) represents an alternative to exposure in the real world (in vivo). It makes it possible to experience close-to-reality situations with the aim of developing, training or rehabilitating specific competences in a controlled environment with a clinician present. VR is a technology that lets a user (e.g., a teacher) be immersed in an artificially created 3D environment (e.g., a virtual classroom) in order to have a realistic experience (e.g., teaching a lesson). This article presents a summary of our research on the contribution VR can make to the learning of efficient vocal behaviors. We assess the applicability and efficacy of a virtual classroom to train teachers’ vocal skills. Following the development of a virtual classroom with 16 animated pupils and noises typical of a school, a validation study was done with 30 teachers. The results suggest that this virtual environment represents an ecologically valid tool that can be used to exercise vocal skills: once they are immersed in the virtual classroom, teachers adopt the specific vocal adaptations they use in teaching situations. A second study assessed the efficacy of a training program using VR for future teachers learning how to communicate in a noisy environment. The preliminary results show that virtual simulations of teaching situations promote an enhanced feeling of self-efficacy regarding communication in noisy environments. VR represents a promising tool with considerable potential for application since the virtual environment may be used not only for working teachers but also for future teachers, for training purposes (prevention), and injured teachers (rehabilitation of dysphonic patients).

The European Public Prosecutor's Office (hereafter EPPO) was established by way of enhanced cooperation, with the adoption of Council Regulation (EU) 2017/1939 (hereafter EPPO Regulation). It has the power to conduct criminal investigations and to directly act as the prosecuting authority before national criminal courts, which is revolutionary. Interestingly, the EPPO Regulation does not explicitly regulate the relation between the EPPO and national judges at the pre-trial stage, who may intervene punctually or, in some cases, even conduct the investigation. Indeed, some civil law systems have a system of shared investigative competences between the public prosecutor and the investigating judge, meaning that the latter conducts a judicial inquiry, while the former is responsible for the prosecution. This raises the delicate question whether a judicial inquiry is compatible with the EPPO Regulation. This article analyses this question, which hugely impacts the implementation of the EPPO, with respect to the Belgian legal system, based on a close reading of the EPPO Regulation and taking into account its drafting history. It will argue that the EPPO Regulation is not per se irreconcilable with a judicial inquiry as the Member States did not wish the EPPO Regulation to alter the way in which criminal investigations are organised at national level. Subsequently, it will examine how an EPPO investigation conducted by an investigating judge can practically function. While the analysis concentrates on Belgium, the underlying reasoning may also be useful for other Member States with a similar legal system. [less ▲]

DIVAnd (Data-Interpolating Variational Analysis, in n-dimensions) is a tool to interpolate observations on a regular grid using the variational inverse method. We have extended DIVAnd to include additional dynamic constraints relevant to surface currents, including imposing a zero normal velocity at the coastline, imposing a low horizontal divergence of the surface currents, temporal coherence and simplified dynamics based on the Coriolis force and the possibility of including a surface pressure gradient. The impact of these constraints is evaluated by cross-validation using the HF (High-Frequency) radar surface current observations in the Ibiza Channel from the Balearic Islands Coastal Ocean Observing and Forecasting System (SOCIB). A small fraction of the radial current observations are set aside to validate the velocity reconstruction. The remaining radial currents from the two radar sites are combined to derive total surface currents using DIVAnd and then compared to the cross-validation data set and to drifter observations. The benefit of the dynamic constraints is shown relative to a variational interpolation without these dynamical constraints. The best results were obtained using the Coriolis force and the surface pressure gradient as a constraint which are able to improve the reconstruction from the Open-boundary Modal Analysis, a quite commonly used method to interpolate HF radar observations, once multiple time instances are considered together.

Partly or fully renewable (co)polymers are gaining interest in both academia and industry. Polyethylene is a widely used polymer, classically derived from fossil fuels, with a high versatility stemming from the introduction of comonomers altering the mechanical properties. The introduction of renewable functionalities into this polymer is highly attractive to obtain functional, tunable, and at least partially renewable polyethylenes. We herein report the introduction of biosourced cyclic carbonates into polyethylene using organometallic-mediated radical polymerization under mild conditions. Molecular weights of up to 14 600 g mol−1 with dispersities as low as 1.19 were obtained, and the cyclic carbonate content could be easily tuned by the ethylene pressure during the polymerization. As a proof of concept, the hydrolysis of the cyclic carbonates of a representative copolymer was explored, and it provided polyethylene-bearing vicinal diols, with a hydrolysis degree of 71%. Given the multitude of chemoselective modifications possible on cyclic carbonates as well as the fact that many allylic- and alkylidene-type cyclic carbonates are accessible from renewable resources, this work opens up an avenue for the design of functional and more sustainable polyethylenes.

In this article we report on the facile preparation of photoactive antibacterial mussel inspired polymer coatings deposited on a stainless steel (SS) substrate from water based precursors. The coating is prepared by the sequential deposition of aqueous based solutions of an anchoring layer based on bio‐inspired glue, a cationic polymer bearing pendent catechols, a nanogel decorated by ortho‐quinones and a photosensitizer of the aminoacridine type. This latter is grafted to the coating by reaction of its amino group with the o‐quinone of the deposited nanogel. The deposition of all layers is followed in‐line by Quartz crystal microbalance coupled with dissipation (QCM‐D) and AFM shows that the thin polymer film repeated the roughness of the SS substrate. The prepared coatings show good mechanical properties applying nanoindentation techniques. The established antibacterial activity of the prepared photoactive polymer coatings on SS against Gram‐negative E. coli strain demonstrate their potential as a power tool for medical applications.

Based on a survey references to colours in Greek hippiatrics text—especially in the Hippiatrica and in book 16 of the Geoponica—this paper examines the lexicon used by horsedoctors to designate colour and the contexts in which it appears, in order to better understand the importance given to colour terms. Colour adjectives are used in three sections of the texts: the external description of the animal (especially the coat and eyes), body fluids and pharmacology (simple and compound drugs). [less ▲]

Generalized additive models (GAMs) are a well-established statistical tool for modeling complex nonlinear relationships between covariates and a response assumed to have a conditional distribution in the exponential family. To make inference in this model class, a fast and flexible approach is considered based on Bayesian P-splines and the Laplace approximation. The proposed Laplace-P-spline model contributes to the development of a new methodology to explore the posterior penalty space by considering a deterministic grid-based strategy or a Markov chain sampler, depending on the number of smooth additive terms in the predictor. The approach has the merit of relying on a simple Gaussian approximation to the conditional posterior of latent variables with closed form analytical expressions available for the gradient and Hessian of the approximate posterior penalty vector. This enables to construct accurate posterior pointwise and credible set estimators for (functions of) regression and spline parameters at a relatively low computational budget even for a large number of smooth additive components. The performance of the Laplace-P-spline model is confirmed through different simulation scenarios and the method is illustrated on two real datasets. [less ▲]

In this article we challenge the assumption that independent professionals (IPros), that is professionals who work as contractors, freelancers, and self-employed individuals, are not within the remit of talent management (TM) theory and practice. The TM literature is almost exclusively focused on traditional employees and largely ignores the external workforce, even if like IPros, they epitomize high-value talent. Moreover, much of the TM literature takes an organizational perspective while the individual perspective remains marginal. Advancing the notion of institutional factors in the macro environment suggested by King and Vaiman, we draw on interviews with 52 IPros in two contrasted institutional contexts to provide an agentic view of TM from outside of the standard employment relationship. Our findings reveal the importance of volition, emotional stability, internal locus of control, and self-efficacy play in IPros effectively managing personal TM strategies. These strategies allow IPros to overcome the empowerment/powerlessness tensions Daubner-Siva et al. call the “talent paradox.” Importantly, the results do not vary between the two national contexts, suggesting that embracing a “total TM” strategy, attentive to the personal characteristics of talent, regardless of the regulatory issues linked to employment status, will produce superior outcomes for all.

Purpose There has been much debate regarding the use of intra-articular injections of platelet-rich plasma (PRP) as symptomatic treatment for knee osteoarthritis. The objective of this consensus was to develop guidelines for PRP injections in knee osteoarthritis according to the French National Authority for Health recommendations. Methods Fifteen physicians from different French-speaking countries (10 rheumatologists, 4 specialists in rehabilitation and sports medicine and 1 radiologist) were selected for their expertise in the areas of PRP and osteoarthritis. A comprehensive literature review was conducted on Medline including all published therapeutic trials, open studies, meta-analysis and systematic reviews focusing on the effects of PRP in knee OA, as well as fundamental studies concerning the characteristics of the various types of PRP and their mechanisms, indexed before April 2019. Using the method recommended by the French National Authority for Health inspired by the Delphi consensus process, 25 recommendations were finally retained and evaluated. The recommendations were classified as appropriate or not appropriate, with strong or relative agreement, or uncertain if a consensus was not achieved. Results Among the 25 recommendations selected, the main ones are the following: (1) Intra-articular injections of PRP are an effective symptomatic treatment for early to moderate knee osteoarthritis. This recommendation was considered appropriate with a relative agreement (Median = 8; rank = 6–9). Level of evidence 1A. (2) A PRP treatment sequence in knee osteoarthritis may include 1–3 injections. This recommendation was considered appropriate with a strong agreement (Median = 9; rank = 7–9). Level of evidence 1A. (3) Leucocytes-poor PRP should be preferred in knee osteoarthritis. This recommendation was considered appropriate with a relative agreement (Median = 8; rank = 5–9). Level of evidence 5. (4) Intra-articular PRP knee injections should be performed under ultrasound or fluoroscopic guidance. This recommendation was considered uncertain with no consensus (Median = 8; rank = 3–9). Level of evidence 5. (5) PRP should not be mixed with an anesthetic or intra-articular corticosteroid. This recommendation was considered appropriate with a relative agreement (Median = 9; rank = 6–9). Level of evidence 5 Conclusion Those 25 recommendations should standardize and facilitate the use of IA PRP injections, which are considered by experts as an effective treatment especially in early or moderate knee OA. Although a strong or relative agreement from the experts was obtained for most of the recommendations, many of them had a very low level of evidence (Level 5) and were principally based on the clinical experience of the experts.

It is now well-established that regulatory T cells (Treg) represent a heterogeneous group of CD4+ T cells. Previous studies have demonstrated that Treg homeostasis was impacted by allogeneic hematopoietic cell transplantation (allo-HCT) and particularly so in patients with chronic graft-versus-host disease (GVHD). Here, we first assessed the ability of various Treg subsets to phosphorylate STAT5 in response to IL-2 or IL-7 stimulation in vitro. We then compared the frequencies of different Treg subtypes in healthy controls as well as in allo-HCT patients with or without chronic GVHD. The highest phosphorylated STAT5 (pSTAT5) signal in response to IL-2 was observed in the CD45RO+CD26−CD39+HLA-DR+ Treg fraction. In contrast, naive Treg were mostly less susceptible to IL-2 stimulation in vitro. Following IL-7 stimulation, most Treg subpopulations upregulated pSTAT5 expression but to a lesser extent than conventional T cells. Compared to healthy controls, allo-HCT patients had lower frequencies of the naive CD45RAbrightCD26+ Treg subpopulation but higher frequencies of the most differentiated memory CD45RO+CD26−CD39+ Treg subpopulations. Further, unbiased analysis revealed that six Treg clusters characterized by high expression of CD25, HLA-DR, and ICOS were significantly more frequent in patients with no or with limited chronic GVHD than in those with moderate/severe chronic GVHD.

In this paper, we discuss the inherent temporal orientation of fear, a matter on which philosophers seem to have contrasting opinions. According to some, fear is inherently presentoriented; others instead maintain that it is inherently future-oriented or that it has no inherent temporal orientation at all. Despite the differences, however, all these views seem to understand fear’s temporal orientation as one-dimensional—that is, as uniquely determined by the represented temporal location of the intentional object of fear. By contrast, we present a view that introduces a two-dimensional account of fear’s temporal orientation. On such a view, we can say that fear is inherently future-oriented, independently of its being about something in the present or in the future. [less ▲]

Est conservée au Musée des Beaux-Arts de Liège, une suite de dix-sept dessins dédiée à l’histoire du patriarche Joseph, formant un ensemble remarquable de modèles destinés à la production de médaillons de verre peint, communément appelés « rondels ». Naguère rapprochés de l’art de Lambert Lombard, ces dessins, copies d’après des originaux perdus, se signalent par d’étonnantes prises de libertés vis-à-vis des Écritures, parfois sources d’erreurs d’interprétation, et par un contraste saisissant entre tradition iconographique et innovation formelle. L’étude intericonique révèle, en effet, que l’auteur du cycle liégeois puisa à des sources variées et parfois longuement éprouvées pour élaborer ses compositions (dessins de Cornelis Anthonisz. et de Jan Swart van Groningen, tondi du Maître de la vie de Joseph, etc), accordant souvent la primauté au formel sur le textuel. En tant que modèles à l’usage de peintres-verriers, ce cycle vétérotestamentaire donna lieu à une intense production verrière ; l’on estime à plus de 250 le nombre de « rondels » exécutés d’après les dessins liégeois ou d’après des modèles apparentés, preuve du vif succès qu’il rencontra, du dernier tiers du XVIe siècle aux premières décennies du XVIIe siècle.

Background: Recommendations are available for assessment criteria for safe return-to-play (RTP) after a lateral ankle sprain. However, their current use among physicians is unknown. Methods: French-speaking physicians in Belgium, France and Switzerland were asked to complete an online survey and report their clinical assessment of selected RTP criteria. Results:The respondent sample (n = 109) included physicians with and without Sports Medicine education, varied level of experience and proportion of athletes in their practice population. Pain was the most selected criterion for safe RTP (90% of physicians), followed by ability to engage in functional tasks (82%), functional instability (73%), range of motion (61%), proprioception (47%), mechanical instability (39%), strength (38%) and swelling (31%). A low proportion of physicians use quantitative measures to assess these criteria (between 4% and 53%). Conclusions: A large proportion of physicians consider the recommended criteria for RTP decisions. However, physicians do not frequently use quantitative measures. [less ▲]
