Growing amount of high dimensional data requires robust analysis techniques. Tree-based ensemble methods provide such accurate supervised learning models. However, the model complexity can become utterly huge depending on the dimension of the dataset. Here we propose a method to compress such ensemble using random tree induced space and L1-norm regularisation. This leads to a drastic pruning, preserving or improving the model accuracy. Moreover, our approach increases robustness with respect to the selection of complexity parameters. [less ▲]

PURPOSE: Increasing the dose to prostatic adenocarcinoma in conformal external beam therapy (EBT) has resulted in increased levels of PSA normalization and increased percentage of biochemical disease-free survival rates. However technical problems due to prostate motion inside the pelvis or patients' set-up make difficult the realization of the EBT boost fields above 72 Gy. Brachytherapy which overcomes these problems was investigated to deliver the boost dose to achieve 85 Gy. PSA nadir which has been identified as the strongest independent predictor of any failure in many studies has been used as the end point for early evaluation of this work. PATIENTS AND METHODS: In a retrospective way we report on 163 patients' PSA kinetics after EBT alone to 68 Gy or EBT first and a brachytherapy boost up to 75 or 85 Gy. RESULTS: At 12 months follow-up, PSA nadirs percentage < or = 0.5 or < or = 1 ng/ml increased from 7.5 and 20.7% after 68 Gy EBT to 49.8 and 71.2% after a brachytherapy boost to deliver 85 Gy (p < 0.0001). In the Cox PH model analysis, the total dose remained the most important factor for predicting PSA normalization. CONCLUSIONS: These results are in accordance with the most recent results published after conformal EBT at the same 80 Gy level of dose. If confirmed on a higher number of patients they could place brachytherapy among the most accurate methods of boosting in the radiation treatment of prostatic carcinoma. [less ▲]

Aortic pseudo-aneurysm is a well-known late complication after surgical repair of aortic coarctation. We report two cases of pseudo-aneurysm of the aortic isthmus evidenced after previous surgical repair of congenital aortic coarctation. These clinical observations give us the opportunity to underline the importance of a specific lifelong medical follow-up for patients who have undergone such surgery. [less ▲]

This report is devoted to the elastic response of hyperbolic notch hinges. Circular, elliptic and parabolic notch hinges have been treated in ealier reports. The adopted step is the same : firstly, for each fundamental load case, the analytical solution is developed in the frame of the classical beam theory ; from this, the asymptotic solution for very narrow hinges is produced ; thirdly, a correction factor is defined, which relates the exact theory to the asymptotic one ; finally, and this is perhaps our main originality, simple but very fair approximations of these correction factors are presented.

Cette démarche fournit des solutions très bien approchées et beaucoup plus simples à utiliser que celles de la littérature, un fait appréciable au niveau de la conception. [less ▲]

Pseudo-Bartter syndrome presents the same clinical and biological characteristics as Bartter syndrome but without primary renal tubule abnormalities. We relate the case of a premature baby presenting at birth with severe hypokalemic metabolic alkalosis associated with hyponatremia and hypochloremia. Maternal blood at the time of delivery showed the same electrolyte perturbations. The baby's mother had suffered from anorexia and vomiting during pregnancy. A few weeks after birth the baby's blood abnormalities had almost returned to normal. Chloride depletion is at the origin of both maternal and fetal hypokalemic alkalosis. [less ▲]

Graphical representations of power systems are systematically used for planning and operation. The coordinate systems commonly used by Transmission System Operators are static and reflect the geographical positions of each equipment of the system. We propose in this work to position on a twodimensional map the different buses of a power system in a way such that their coordinates also highlight some other physical information related to them. These pseudo-geographical representations are computed by formulating multidimensional scaling problems which aim at mapping a distance matrix combining both geographical and physical information into a vector of two-dimensional bus coordinates. We illustrate through examples that these pseudo-geographical representations can help to gain insights into the power system physical properties. [less ▲]

A 85 years old patient was hospitalized because of thoracic pain, lasting since three months. He suffered of Parkinson's disease and he was a smoker. The pain increased with cough and Vansalva's test. His left arm was cianotic. An arterial obstruction was suspected. Dopler ultrasound of the left arm confirmed a partial obstruction of the left axillar artery. Surprisingly, thoracic scan and MRI found an important cardiomegaly. The heart was in contact with the diaphragmatic and gastric region. Ecocardiography confirmed a 7 cm pseudo aneurysm of the left ventricle. Coronarography showed extreme hypokinesia of the left ventricle. There was also an obstruction of the right coronary and 50 % stenosis of the left coronary. Pseudo aneurysm was a complication of myocardial infarction of the left ventricle. Surgery was offered to the patient, but he declined the intervention. He was dismissed with medical treatment and anticoagulation. The patient deceased three months later. [less ▲]
