Résumé : Les études en oncologie pédiatrique décrivent une relativement bonne qualité de vie chez les enfants survivants de cancer. À ce jour, peu d’études se sont intéressées aux parents d’un enfant survivant de cancer. Soixante-et-un parents sont recrutés dans les hôpitaux belges. Trois groupes de parents sont constitués : les parents dont l’enfant est à 4 ans de rémission (groupe 1), à 5 ans de rémission (groupe 2) et à 6 ans de rémission (groupe 3). Des échelles cliniques et une tâche de Stroop émotion sont administrées. Les parents (des 3 groupes) présentent une faible tolérance à l’incertitude, ont des inquiétudes excessives quant à l’évolution de la santé de leur enfant et souffrent de symptômes anxieux. Le Stroop émotion révèle un biais cognitif de l’attention en faveur des stimuli de nature menaçante. L’étude met en exergue l’importance de détecter les parents intolérants à l’incertitude lors du diagnostic d’annonce du cancer et leur suivi psychologique continu une fois les traitements terminés.

Paedomorphosis is an alternative process to metamorphosis in which adults retain larval traits at the adult stage. It is frequent in newts and salamanders, where larvae reach sexual maturity without losing their gills. However, in some populations, larvae overwinter in water, while remaining immature. These alternative ontogenetic processes are of particular interest in various research fields, but have different causes and consequences, as only paedomorphosis allows metamorphosis to be bypassed before maturity. It is thus relevant to efficiently identify paedomorphs versus overwintering larvae. In this context, the aim of this paper was threefold: firstly, to perform a meta-analysis of the identification procedures carried out in the literature; secondly, to determine the effectiveness of body size to make inferences about adulthood by surveying natural newt populations of Lissotriton helveticus and Ichthyosaura alpestris, and thirdly, to propose easy guidelines for an accurate distinction between large larvae and paedomorphs based on an external sexual trait, which is essential for reproduction — the cloaca. More than half of the studies in the literature do not mention the diagnostic criteria used for determining adulthood. The criteria mentioned were the presence of mature gonads (10%), eggs laid (4%), courtship behaviour (10%), and external morphological sexual traits (39%) including the cloaca (24%). Body-size thresholds should not be used as a proxy for paedomorphosis, because overwintering larvae can reach a larger size than paedomorphs within the same populations. In contrast, diagnosis based on cloacal external morphology is recommended, as it can be processed by the rapid visual assessment of all caught specimens, thus providing straightforward data at the individual level for both sexes.

Paedomorphosis is a major evolutionary process that bypasses metamorphosis and allows reproduction in larvae. In newts and salamanders, it can be facultative with paedomorphs retaining gills and metamorphs dispersing. The evolution of these developmental processes is thought to have been driven by the costs and benefits of inhabiting aquatic versus terrestrial habitats. In this context, we aimed at testing the hypothesis that climatic drivers affect phenotypic transition and the difference across sexes because sex-ratio is biased in natural populations. Through a replicated laboratory experiment, we showed that paedomorphic palmate newts (Lissotriton helveticus) metamorphosed at a higher frequency when water availability decreased and metamorphosed earlier when temperature increased in these conditions. All responses were sex-biased, and males were more prone to change phenotype than females. Our work shows how climatic variables can affect facultative paedomorphosis and support theoretical models predicting life on land instead of in water. Moreover, because males metamorphose and leave water more often and earlier than females, these results, for the first time, give an experimental explanation for the rarity of male paedomorphosis (the ‘male escape hypothesis’) and suggest the importance of sex in the evolution of paedomorphosis versus metamorphosis.

Pliosaurids are iconic marine reptiles that dominated marine ecosystems during the Jurassic and the Cretaceous. These giant predators met their demise during the early Late Cretaceous but the final chapter of their long evolutionary history remains barely documented. Prompted by the discovery of a peculiar and very well preserved new taxon from Russia, we compute the evolution of pliosaurid disparity from their Early Jurassic radiation to their Late Cretaceous extinction. Despite a patchy Early Cretaceous fossil record, we show pliosaurids reached their maximal disparity during the Hauterivian-Barremian interval, suggesting a strong Early Cretaceous recovery from the apparently low phenotypic disparity of Late Jurassic pliosaurids. By using cladistic and ecomorphological data, we show that pliosaurids have repeatedly evolved slender-snouted polycotylid-like morphologies in each of their temporal radiations (Early Jurassic, Middle Jurassic and Early Cretaceous), demonstrating a more complex evolutionary history than their traditional representation as gigantic apex predators of Mesozoic marine ecosystems suggests. The extinction of pliosaurids during the Turonian (early Late Cretaceous) appears preceded by a late Early Cretaceous contraction of their disparity, the trajectory documented in ichthyosaurs, another successful marine reptile clade that disappeared during the Cenomanian-Turonian interval.

Les illégalités liées au traitement différentiel des genres reposent notamment sur la présence de stéréotypes sexistes. L’article illustre comment les attitudes subjectivement positives à l’égard des femmes que l’on peut qualifier de stéréotypes sexistes bienveillants influencent tant positivement que négativement la façon dont les femmes sont perçues par le système judiciaire. L’article souligne également au travers des représentations liées aux violences sexuelles l’impact des stéréotypes sexistes hostiles sur la perception de la légalité, de la légitimité perçue du passage à l’acte et du statut des victimes.

Nonlinear aeroelasticity has become an increasingly popular research area over the last 20-30 years. There have been many driving forces behind this development, including faster computers, increasingly flexible structures, automatic control systems for aircraft and other engineering products, new materials with nonlinear characteristics etc. Introduction to Nonlinear Aeroelasticity covers the theoretical basics in nonlinear aeroelasticity and applies the theory to practical problems. As nonlinear aeroelasticity is a combined topic, necessitating expertise from different areas, this book also covers areas such as nonlinear dynamics, bifurcation analysis, numerical methods and others. The emphasis throughout is on the practical application of the theories and methods, so as to enable the reader to apply their newly acquired knowledge [less ▲]

Les perforations intestinales grêles sont rares et ont de multiples étiologies. Nous rapportons le cas d'un patient âgé de 52 ans présentant des douleurs chroniques en fosse iliaque gauche depuis plus de 9 mois. L'imagerie par entéro-IRM et CT scanner a permis de mettre en évidence d'une manière rétrospective une perforation intestinale grêle couverte par un corps étranger. L'intérêt de cette observation est de montrer d'une part les signes indirects de la perforation grêle et d'autre part le caractère migrant du corps étranger. [less ▲]

In this paper, we study the problem of predicting Internet path changes and path performance using traceroute measurements and machine learning models. Path changes are frequently linked to path inflation and performance degradation; therefore, predicting their occurrence is highly relevant for performance monitoring and dynamic traffic engineering. We introduce NETPerfTrace, an Internet Path Tracking system capable of forecasting path changes and path latency variations. By relying on decision trees and using empirical distribution based input features, we show that NETPerfTrace can predict (i) the remaining life time of a path before it actually changes and (ii) the number of path changes in a certain time-slot with high accuracy. Through extensive evaluation, we demonstrate that NETPerfTrace highly outperforms DTRACK, a previous system with the same prediction targets. NETPerfTrace also offers path performance forecasting capabilities. In particular, it can predict path latency metrics, providing a system which could not only predict path changes but also forecast their impact in terms of performance variations. As an additional contribution, we release NETPerfTrace as open software to the networking community. [less ▲]
