Positioning is a fundamental issue in mobile robot applications that can be achieved in multiple ways. Among these methods, triangulation with active beacons is widely used, robust, accurate, and flexible. In this paper, we analyze the performance of an original system, introduced in a one of our previous papers, that comprises a rotating receiver and beacons that send an On-Off Keying modulated infrared signal. The probability density function of the measured angles is established and discussed. In particular, it is shown that the proposed estimator is a non biased estimator of the beacon angular position. We also evaluate the theoretical results by means of both a simulator and measurements. [less ▲]

The paper reports on a 1996 incident in the Greek power system that had all the characteristics of voltage instability and the subsequent analyses and countermeasures. Voltage stability analysis is performed by both NTUA and ULg software tools that give identical simulation results. After the upgrades performed by PPC a considerable increase in the maximum power that can be fed to the Athens area is achieved. Finally, secure operation limits of the upgraded system are calculated. [less ▲]

Odor is an essential characteristic and a quality marker in baby foodstuff, like a partially hydrolyzed and pregelatinized rice flour. The rice flour study by active sampling and TD-GC/MS highlighted the presence of three aldehydes: Hexanal, Octanal, Nonanal. These compounds are known to be caused by lipid oxidation, one of the major alteration reactions in food. The Method was developed and valited on a large range for the three aldehydes. It was then applied to the rice fllour to determine if it can be used to follow the effect of ageing on the aldehydes production. [less ▲]

The identification of mutations that cause familial Parkinson's disease (PD) provides a framework for studies into pathways that may be perturbed also in the far more common, non-familial form of the disorder. Following this hypothesis, we have examined the gene regulatory network that links alpha-synuclein and parkin pathways with dopamine metabolism in neuropathologically verified cases of sporadic PD. By means of an in silico approach using a database of eukaryotic molecular interactions and a whole genome transcriptome dataset validated by qRT-PCR and histological methods, we found parkin and functionally associated genes to be up-regulated in the lateral substantia nigra (SN). In contrast, alpha-synuclein and ubiquitin carboxyl-terminal hydrolase L1 (UCHL1) gene expression levels were significantly reduced in both the lateral and medial SN in PD. Gene expression for Septin 4, a member of the GTP-binding protein family involved in alpha-synuclein metabolism was elevated in the lateral parkinsonian SN. Additionally, catalase and mitogen-activated protein kinase 8 and poly(ADP-ribose) polymerase family member 1 (PARP1) known to function in DNA repair and cell death induction, all members of the dopamine synthesis pathway, were up-regulated in the lateral SN. In contrast, two additional PD-linked genes, glucocerebrosidase and nuclear receptor subfamily 4, group A, member 2 (NR4A2) showed reduced expression. We show that in sporadic PD, parkin, alpha-synuclein and dopamine pathways are co-deregulated. Alpha-synuclein is a member of all three gene regulatory networks. Our analysis results support the view that alpha-synuclein has a central role in the familial as well as the non-familial form of the disease and provide steps towards a pathway definition of PD.

Following the entry into force of the ‘Decree defining the landscape of Higher Education’ in the French-speaking Community of Belgium (18-12-2013), the opportunity is given to First year students to break their first academic year into two and receive a reduced curriculum, thus reflecting a legislator’s awareness of the need to support First Year students in reaching a certain level of success during this crucial transitional phase of their studies. More specifically, at the Faculty of Veterinary Medicine of the University of Liège, each First-Year student, is offered the option to sign an agreement for a reduced program during the second quarter (according to the ‘Decree related to the studies of Veterinary Sciences’, 13-7-2016) including a maximum of 35 ECTS and comprising all the courses of the first quarter. Since very limited studies exist on such reduced programs as possible vectors of integration or as success factors, this communication aims to present the results of a research investigating the positive and negative perceptions of a group of students who experienced an accordingly adapted curriculum during the academic year 2017/2018. For each of the five courses constituting their second quarter program, those students have benefited from original remediation activities (including various formative evaluation activities, methodological support, online assignments and theoretical revisions) designed by the concerned faculties with the help of a pedagogical advisor (also available to offer an adequate follow-up to those students in the context of an ULiège FYE project called ‘Feedbacks 1st Year’). Among the fourteen First Year students who chose to sign the agreement (with all its implication in terms of waiving various aspects of their First-Year cursus), ten agreed to join the assessment process of this program, taking part in semi-directed interviews. The interview data were then analyzed thematically using NVivo qualitative analysis software in order to explore students self-reported behaviors and perceptions positively / negatively related to the studied program : reflective and self-regulation abilities (Nicol, 2009), sense of controllability (Viau, 2005), perceived quality of interactions with both faculties and peers (Tinto, 1993), judgements of competence and task difficulty (Wiegfield & Eccles, 2000). Since several of the analyzed factors are described as predictors of further engagement or performance of students according to the literature, those results (as the experience itself) could be both inspiring and transferable to various kinds of adapted First Year programmes aiming to give students a second chance to make a successful transition from high school to university.

Serum samples of goats experiencing natural and experimental infections and/or reactivation of caprine herpesvirus 1 (CpHV.1) were analysed with neutralization and Western blotting (WB) tests. WB immunological patterns resulted differently and related to neutralizing titers. In serum samples having neutralizing titer 1:2-1:4, antibodies to two proteins of Mw of 150 and 34 kDa were present. Antibodies against several proteins, two of those being characterized by monoclonal antibodies as gB and gC, were visualized by WB in sera having titer >= 1:8. The neutralizing antibody titers and the pattern of antibody reactivity were hypothesized to modulate the reactivation and re-excretion process of CpHV.1.

A combination of 3MeV proton PIXE-PIGE, MA-XRF and 10-15 MeV proton activation analysis has been recently applied on the external beam line of the cyclotron of IPNAS/CEA laboratory from the University of Li`ege, and thus, to a wide variety of archaeological specimens (glass, pottery (terra sigillata), mortars and pigments) all provided by on-going studies and excavations of housing materials, wall decorations, and vessels led on two remarkable Roman sites: First, from an important agricultural complex excavated on an artificial terrace from a republican town, Artena, located, 40 km South-East from Rome, near the Via Latina and the Campania and second, from the Domus dei bucrani, a house dating from the end of the Republican era discovered on the site of the Schola of the Trajan in Ostia. The aim of the present work is to explore and report the specific analytical interests of Charge Particle Activation Analysis implemented with protons ranging from 10 to 15 MeV, as a non-invasive analytical technique for the detection of elements with Z = 11-40 and beyond, and to address its suitability to solve questions raised by archaeologists. We present in this paper the preliminary results obtained following methodologies reported in recent pioneering and more recent works [1-4] and emphasize on the achieved sensitivities (Limits of Detections) for elements as Ca, Ti, V, Cr, Fe, Cu, Zn, As, Sr, Y, Zr and Sb ranging from percentage to parts per million (ppm) levels.

Bovine herpesvirus 4 (BHV-4) DNA sequences located outside the gene blocks conserved among the gammaherpesviruses BHV-4, herpesvirus saimiri (HVS) and Epstein-Barr virus (EBV) were analysed. Twelve potential open reading frames (ORFs) were found. Protein database comparisons showed that no ORF translation products were similar to proteins encoded by alpha- or betaherpesviruses. Nevertheless, six of the ORFs were homologous in amino acid sequences to proteins encoded by HVS but apparently not to those encoded by EBV. Furthermore, the location and orientation of these six ORFs in the BHV-4 genome were similar to the corresponding ORFs in the HVS genome. No genes homologous to known cellular genes were found in the BHV-4 genome; this feature is the major difference between the BHV-4 and HVS genomes with regards to the overall gene content. [less ▲]
