The yellowtail clownfish Amphiprion clarkii is able to close its mouth very quickly by means of the cerato-mandibular (c-md) ligament, a synapomorphic trait of Pomacentridae joining the hyoid bar to the medial part of the lower jaw. This fast closure induces tooth collision, thus producing sounds that the clownfish uses during agonistic behaviors. To investigate whether this rapid jaw movement is also used during feeding, we analyzed the kinematics of sound production and feeding. Sound production, feeding on live planktonic prey, and feeding on food attached to tweezers were filmed with a high-speed camera. Three kinds of kinematic patterns were detected and were associated with the two different types of food presented: one performed to catch planktonic prey (PP), and two (called B-1 and B-2) to bite attached food items. The kinematic pattern of B-2 is similar to that observed during sound production (SP) and the transection of the c-md ligament highlights that sound production and biting-2 motions are dependent on this morphological trait. Our data show that the c-md ligament in addition to its role in sound production allows duplication of the mouth closing mechanism during feeding. This highlights the key role played by the c-md ligament in sound production and feeding on attached prey. [less ▲]

Objective: Based on the case study of Jeanne, the objective of this article is to study patterns of anorexic people’s specific being-in-the-world. We seek to identify the core vulnerability features of anorexic existence, beyond the dimension of feeding alone. The identification of a psychopathological structure will result in a better understanding of Jeanne’s clinical situation and will help to formulate psychotherapeutic and prophylactic recommendations. Method: A phenomenological and ethological approach allows us to see past the strictly medical symptoms (eating disorder). The evolutionary perspective highlights the adaptive dimension of this disorder (e.g., in extreme situations such as famine). Specifically, Demaret’s ethological hypothesis identifies altruism (feeding altruism and generalized altruism) as the core feature of anorexic conduct. Phenomenological reflection (phenomenological psychopathology and phenomenological philosophy) appears to complement the ethological approach. Phenomenology distinguishes two kinds of bodies: the Leib (emotional, subjective and experienced in the first person) and the Körper (devitalized, objective and experienced in the second person). Merleau-Ponty’s works highlight the difference between the touching body and the touched body. These proposals show the problematic of the other in body configuration. It is in precisely this connection that anorexic existence is specific. Sartre’s phenomenology and the lived-body-for-others is the final step of our reasoning to arrive at a configuration of intersubjectivity. Results: The analysis of Jeanne’s case, combined with ethological and phenomenological perspectives, demonstrates that the real psychopathological structure of anorexic subjectivity rests on specific interaction modes. The notions of altruism, lived-body-for-others, and intersubjectivity highlight an emotional existence including shame in the eyes of others, and especially an imbalance between self-preservation and care for others. Conclusions: All our thinking suggests that so-called “denial” is a psychological mechanism that should be reconsidered. Denial is not a mechanism of anorexic subjects alone, but is also a process encountered both in the patient’s family and in the therapeutic environment. Anorexic denial is based on anosognosia and the refusal to see one’s own thinness, while other people’s denial constitutes a widespread inability to perceive the altruism and intersubjective problematic on which the existence of an anorexic subject fundamentally depends.

Fossils of Mesozoic vertebrates are rare in Scotland, particularly specimens of marine reptiles such as plesiosaurs and ichthyosaurs. We describe a suite of ichthyosaur fossils from the Early to Middle Jurassic of Skye, which to our knowledge are the first ichthyosaurs from Scotland to be described and figured in detail. These fossils span approximately 30 million years, from the Sinemurian to the Bathonian, and indicate that ichthyosaurs were a major component of Scottish marine faunas during this time. The specimens include isolated teeth that could represent the most northerly known occurrences of the widespread Sinemurian species Ichthyosaurus communis, a characteristic component of the famous Lyme Regis faunas of England, suggesting that such faunas were also present in Scotland during the Early Jurassic. An associated humerus and vertebrae from Toarcian–Bajocian-aged deposits are named as a new genus and species of basal neoichthyosaurian, Dearcmhara shawcrossi. The taxonomic affinities of this taxon, which comes from a critical but poorly sampled interval in the fossil record, suggest that non-ophthalmosaurid neoichthyosaurians dominated European assemblages around the Early–Middle Jurassic boundary, and were later replaced by ophthalmosaurids, whose radiation likely took place outside Europe. Many of these specimens were collected by amateurs and donated to museum collections, a co-operative relationship essential to the preservation of Scotland’s fossil heritage. [less ▲]

Anatomical, systematic, and paleobiogeographical data on the Devonian antiarchs from Belgium are reviewed, updated and completed thanks to new data from the field and re-examination of paleontological collections. The material of Bothriolepis lohesti Leriche, 1931 is enhanced and the species better described. An undetermined species of Bothriolepis is recorded from the Famennian of Modave (Liège Province), one species of Asterolepis redescribed from the Givetian of Hingeon and another one described from the Givetian of Mazy (Namur Province). Grossilepis rikiki sp. nov. is recorded from the Famennian tetrapod-bearing locality of Strud (Namur Province) and from the Famennian of Moresnet (Liège Province). It is the first occurrence of Grossilepis after the Frasnian and on the central southern coast of the Euramerican continent. Its occurrence in the Famennian of Belgium may be the result of a late arrival from the Moscow Platform and the Baltic Depression, where the genus is known from Frasnian deposits. Remigolepis durnalense sp. nov. is described from the Famennian of Spontin near Durnal (Namur Province). Except for the doubtful occurrence of Remigolepis sp. in Scotland, this is the first record of this genus in Western Europe. Its occurrence in Belgium reinforces the strong faunal affinities between Belgium and East Greenland and the hypothesis of a hydrographical link between the two areas during the Late Devonian.

La crise généralisée qui, depuis quelques années, a affaibli les économies de nombre d’états, a eu des conséquences sur la typologie des migrations internationales : les trajectoires, les projets, les destinations, les départs se sont modifiés en fonction de nouveaux facteurs auxquels les individus et les groupes étaient confrontés . A côté de ces macro-dynamiques globales, la crise a également engendré des changements dans la vie quotidienne des migrants lorsqu’ils étaient déjà partis et qu’ils s’étaient déjà installés ailleurs. Dans ce cadre, ma contribution vise à analyser les pratiques d’approvisionnement alimentaire d’un groupe de migrantes marocaines en Italie mettant en place des stratégies pour faire face aux conséquences concrètes de la crise économique (notamment la diminution de leur pouvoir d’achat en conséquence de leur précarité professionnelle). Au travers de plusieurs déplacements dans la ville où elles habitaient et de la mobilisation des réseaux familiaux alimentant des circuits informels d’échange de biens, ces femmes satisfaisaient leurs différentes exigences – parmi lesquelles le désir de performer des préparations propres à leur mémoire incorporée – tout en répondant aux contraintes économiques déterminées par la crise. Je vais ainsi démontrer qu’en dépit des difficultés rencontrées, ces femmes arrivaient à exercer une agency dans le nouvel espace vécu et à se positionner de façon active au travers de leurs choix et conduites quotidiennes.

In this study, we report the synthesis of a nanoscaled drug delivery system, which is composed of a gold nanorod-like core and a mesoporous silica shell (GNR@MSNP) and partially uploaded with phase-changing molecules (1-tetradecanol, TD, Tm 39 degrees C) as gatekeepers, as well as its ability to regulate the release of doxorubicin (DOX). Indeed, a nearly zero premature release is evidenced at physiological temperature (37 degrees C), whereas the DOX release is efficiently achieved at higher temperature not only upon external heating, but also via internal heating generated by the GNR core under near infrared irradiation. When tagged with folate moieties, GNR@MSNPs target specifically to KB cells, which are known to overexpress the folate receptors. Such a precise control over drug release, combining with the photothermal effect of GNR cores, provides promising opportunity for localized synergistic photothermal ablation and chemotherapy. Moreover, the performance in killing the targeted cancer cells is more efficient compared with the single phototherapeutic modality of GNR@MSNPs. This versatile combination of local heating, phototherapeutics, chemotherapeutics and gating components opens up the possibilities for designing multifunctional drug delivery systems. [less ▲]

The present experiment investigates whether young children are able to reduce their false recognition rate after distinctive encoding by implementing a strategic metacognitive rule. Seventy-two children, aged 4, 6, and 9 years, studied two lists of unrelated items. One of these lists was visually displayed (picture condition) while the other was presented auditorily (word condition). After each study phase, participants completed recognition tests. Finally, they answered questions about their explicit knowledge of the distinctive-encoding effect. The results revealed that even the youngest children in our sample showed a smaller proportion of intrusions in the picture condition than in the word condition. Furthermore, the results of the signal detection analyses were consistent with the hypothesis that the lower rate of false recognitions after picture encoding results from the implementation of a conservative response criterion based on metacognitive expectations (distinctiveness heuristic). Moreover, the absence of correlation between children’s explicit knowledge of the distinctiveness rule and their effective use of this metacognitive heuristic seems to indicate that its involvement in memory decisions could be mediated by implicit mechanisms.

This paper proposes a new control scheme for the Voltage Source Converters (VSCs) of a High Voltage Direct Current (HVDC) grid connecting asynchronous AC systems, so that the latter can mutually support their frequencies after a disturbance. The scheme involves no communication between VSCs. It is activated upon detection of a significant frequency deviation, with the possibility to limit the support requested from other AC systems. It relies on an integral control enforcing the frequency droop characteristics (of classical speed governors), in addition to the voltage-droop control of VSCs. The controller is tuned to emulate the response of a power plant, while avoiding excessive transients in the HVDC system, and limiting the impact on the other AC systems. [less ▲]

The aim of this study is to evaluate the efficacy of frozen Azawak colostrum supplementation on body weight (BW), average daily gain (ADG), reproductive parameters (mean age at first parturition, fertility, fecundity, prolificacy) and mortality rate among red kids. The study was conducted at the goat farm secondary centre of Maradi in Niger from September 2010 to September 2011. The control animals (n = 20) were left with their mother, while the treatment animals (n = 20) received in addition 50 ml/animal/day of bovine colostrum at birth and 15 ml/animal/day from d2 to d15. Weight was measured weekly from birth to d365. Mortalities were also recorded over the same period. For reproductive parameters, observations began at weaning (d197). Growth rate was higher (p < 0.001) in supplemented animal, and the treatment effects on ADG were observed up to 150 day after the end of supplementation. A similar long-lasting trend was also observed in relation to the mortality rate (25% for ColG vs. 55% for ConG; p = 0.05). The age at first kidding tended to be lower in the treated group (13.8 0.7 vs. 14.1 0.8 month; p < 0.1). In conclusion, mild bovine colostrum supplementation induces a long-lasting positive impact on growth rate and to a lower extent on reproduction parameters and survival rate. [less ▲]

Because of their widely spread use in many industries, composites are the subject of many research campaigns. More particularly, the development of both accurate and flexible numerical models able to capture their intrinsically multiscale modes of failure is still a challenge. The standard finite element method typically requires intensive remeshing to adequately capture the geometry of the cracks and high accuracy is thus often sacrificed in favor of scalability, and vice versa. In an effort to preserve both properties, we present here an extended finite element method (XFEM) for large scale composite fracture simulations. In this formulation, the standard FEM formulation is partially enriched by use of shifted Heaviside functions with special attention paid to the scalability of the scheme. This enrichment technique offers several benefits, since the interpolation property of the standard shape function still holds at the nodes. Those benefits include (i) no extra boundary condition for the enrichment degree of freedom, and (ii) no need for transition/blending regions; both of which contribute to maintain the scalability of the code. Two different cohesive zone models (CZM) are then adopted to capture the physics of the crack propagation mechanisms. At the intralaminar level, an extrinsic CZM embedded in the XFEM formulation is used. At the interlaminar level, an intrinsic CZM is adopted for predicting the failure. The overall framework is implemented in ALYA, a mechanics code specifically developed for large scale, massively parallel simulations of coupled multi-physics problems. The implementation of both intrinsic and extrinsic CZM models within the code is such that it conserves the extremely efficient scalability of ALYA while providing accurate physical simulations of computationally expensive phenomena. The strong scalability provided by the proposed implementation is demonstrated. The model is ultimately validated against a full experimental campaign of loading tests and X-ray tomography analyses for a chosen very large scale. [less ▲]

Context: One in 4 men in the US aged >50 will suffer an osteoporosis-related fracture. Less data are available on osteoporosis treatment in men than women. Objective: Evaluate denosumab therapy in men with low BMD. Design: Phase 3 study with two treatment periods: a previously reported 12-month double-blind, placebo-controlled phase and a 12-month open-label phase. Setting: Multicenter in North America and Europe. Participants: 228 men entered the open-label phase and 219 completed the study. Intervention: Men from the original denosumab (long-term) and placebo (crossover) groups received denosumab 60 mg SC every 6 months. Main Outcome Measures: BMD, serum C-telopeptide (sCTX), and safety. Results: During the open-label phase, continued BMD increases occurred with long-term denosumab treatment (2.2% lumbar spine; 0.9% total hip; 1.3% femoral neck; 1.3% trochanter; and 0.2% 1/3 radius), resulting in cumulative 24-month gains from baseline of 8.0%, 3.4%, 3.4%, 4.6%, and 0.7%, respectively (all P<0.01). The crossover group showed BMD gains after 12 months of denosumab treatment similar to the long-term denosumab group during the first treatment year. Significant reductions in sCTX were observed following denosumab administration. Adverse events rates were similar between groups and no new safety signals identified. Conclusions: In men with low BMD, denosumab treatment for a second year continued to increase BMD, maintained reductions in bone resorption, and was well tolerated. BMD increased in men initiating denosumab during the second year. These effects were similar to those previously seen in postmenopausal women with osteoporosis and men with prostate cancer on androgen deprivation therapy. [less ▲]

Jatropha curcas, ou Pourghère, est un arbuste de la famille des Euphorbiacées, largement répandu dans les pays tropicaux. Ses graines sont riches d'une huile pouvant servir de biocarburant dans les moteurs diesels modifiés. La plante est attaquée par divers insectes ravageurs appartenant principalement aux ordres des Hétéroptères, Coléoptères et Orthoptères. Ils provoquent des dégâts sur les fruits, les inflorescences et les feuilles. Les ravageurs les plus fréquemment observés sur J. curcas sont des punaises du genre Pachycoris (Hétéroptère : Scutelleridae), qui sont largement répandues au Mexique, en Australie, aux États-Unis, au Brésil et au Nicaragua. Ces punaises causent des dégâts importants sur les fruits et provoquent la malformation des graines, et avec elle une réduction de la teneur en huile. Même si les arbustes de Jatropha sont victime d'infestations d'insectes, plusieurs études démontrent l'effet insecticide de son huile contre des ravageurs importants tels que Busseola fusca (Fuller) (Lépidoptère : Noctuidae), Sesamia calamistis Hampson (Lépidoptère : Noctuidae), Aphis gossypii Glover (Homoptère: Aphididae) et Callosobruchus chinensis L.
