The integrated water resource management problems require studying efficiently seawater intrusion at local and regional scale and identifying in real time the seawater/freshwater interface dynamic. Hydrogeological modeling is widely used to predict seawater intrusion if additional natural or man‐made factors are modified. These models are currently calibrated using measured heads and salt mass fractions in boreholes, which generally result in sparse data coverage. Within this scope, non to minimally invasive geophysical techniques like electrical resistivity tomography (ERT) or time‐domain electromagnetic method are becoming increasingly popular, given their relatively greater spatial horizontal resolution compared to borehole observations. We present a comparison between both a sequential and joint approach to calibrate seawater intrusion models using ERT. The former consists of constraining hydrogeological parameters using ERT derived parameters and relies on sequential inversions of the geophysical and hydrogeological data using a given petrophysical relationship. The second approach in based on simultaneous inversion of petrophysical and hydrogeological data using electrical resistance data as data. It is performed by coupling an inversion code with two hydrogeological and geophysical modeling codes through a petrophysical conversion. This investigation was performed on a densitydependent flow and transport numerical (three/two‐dimensional) simulation study from complex and realistic heterogeneous models. In the sequential approach, the simulations showed that only the shallow salt concentration of the seawater/freshwater transition zone could be recovered for different time‐lapse, due to poorly resolved regions in depth. The capability of image appraisal indicators (cumulative sensitivity and resolution) has been analyzed to emphasize the discrepancy between the targeted and imaged parameter values. On the other hand, the preliminary coupled inversion avoids the regularization bias introduced by ERT and addresses the non‐stationarity of the petrophysical relationship. [less ▲]

The Guidelines for Myocardial Revascularization of the European Society of Cardiology (ESC) and European Association for Cardio-Thoracic Surgery (EACTS) are the very first reported consensus document, by a writing committee balanced between non-interventional and interventional cardiologists as well as cardiac surgeons, on this specific issue. Given the strong impact that ischaemic heart disease has on the survival and quality of life of the individual as well as the economic implications for society, the importance of the ESC/EACTS guidelines is obvious.

A strategy for multitrait genetic evaluation of US Jersey type traits that integrates an accounting for heterogeneous (co) variances was developed. The proposed method allows joint estimation of variances and effects. The new model is theoretically better than the current one and should give less biased rankings of animals, especially for cows. The heterogeneous variance adjustment reduced standard deviations and linear regression coefficients of sampling variances on time substantially. Mendelian sampling variances for 1997 animals with and without adjustments were nearly identical. [less ▲]

Decision forests such as Random Forests and Extremely randomized trees are state-of-the-art supervised learning methods. Unfortunately, they tend to consume much memory space. In this work, we propose an alternative algorithm to derive decision forests under heavy memory constraints. We show that under such constraints our method usually outperforms simpler baselines and can even sometimes beat the original forest. [less ▲]

The basic mechanisms of hernia formation remain mostly unknown, but several studies suggest that a connective-tissue pathology, affecting mainly the collagen metabolism, could play a role in the genesis of groin hernias. It would be interesting to know if this pathology can express some clinical signs other than the hernia. Our study focused on the joint mobility and the diagnostic criteria for benign joint hypermobility syndrome. Sixty male adult patients with inguinal hernias and 62 control subjects without hernias, age-matched, were compared, taking into account anamnestic criteria (family history of groin hernia, joint sprain, joint dislocation, skin striae, major arthralgia) and joint mobility. This was assessed by using Beighton criteria and measuring the range of movement of five joints (extension of the fifth finger, thumb, wrist, elbow, and knee). The frequency of the positive anamnestic criteria was not statistically different between the two groups. Nevertheless, a family history of groin hernia was observed in 25% of the hernia patients, against 16% in the control subjects ( P=0.23). The mean Beighton score was 0.30 in the hernia patients and 0.29 in the control population. The movement range of the five examined joints was similar in the two groups. In conclusion, patients with a groin hernia presented neither joint hypermobility nor clinical evidence of a benign joint hypermobility syndrome. Although abnormal collagen metabolism is likely implicated in hernia formation, this pathology does not seem to have clinical repercussion on joint mobility. [less ▲]

Density functional theory (DFT) calculations have been performed to address the structure of nitroxide intermediates in controlled radical polymerization. In a preliminary step, the reliability of different theoretical methods has been substantiated by comparing calculated hyperfine coupling constants (HFCCs) to experimental data for a set of linear and cyclic alkylnitroxyl radicals. Considering this tested approach, the nature of different nitroxides has been predicted or confirmed for (a) the reaction of C-phenyl-N-tert-butylnitrone and AIBN, (b) N-tert-butyl-α-isopropylnitrone and benzoyl peroxide, (c) tert-butyl methacrylate polymerization in the presence of sodium nitrite as mediator, and (d) for the reaction of a nitroso compound with AIBN. Values of HFCC experimentally determined have been confirmed by DFT calculations. [less ▲]

In this paper, recent developments aiming at characterising the behaviour of joints met in building structures subjected to exceptional events will be summarised. Section 2 gives an overview of the investigations conducted on joints subjected to combined bending moments and axial loads. The behaviour of joints subjected to elevated temperatures associated to some specific exceptional events is then addressed in Section 3. Finally, the development of strain rate effects in joint components when subjected to dynamic actions is considered in Section 4. [less ▲]
