Vibrational modes of circular free plates under tension

The vibrational frequencies of a plate under tension are given by the eigenvalues $\omega$ of the equation $\Delta^2u-\tau\Delta u=\omega u$. This paper determines the eigenfunctions and eigenvalues of this bi-Laplace problem on the ball under natural (free) boundary conditions. In particular, the fundamental modes --- the eigenfunctions of the lowest nonzero eigenvalue --- are identified and found to have simple angular dependence.Comment: 17 pages.

Glycemic Control Protocol Comparison using Virtual Trials

DTM2011 handbook/programme is given in files and also available as a hard copyBackground: Several accurate glycemic control (AGC) protocols for critical care patients exist but making comparisons is very hard. Objective: This study uses clinically validated virtual patient methods to compare safety and performance for several published AGC protocols. Method: Clinically validated virtual trials were run on 371 patients (39,481 hours, 26,646 measurements) created from the SPRINT AGC cohort. For protocols that do not modulate feed rates enteral nutrition was held at 100% of ACCP goal (25kcal/kg/day) when the patients were clinically fed, and parenteral nutrition rates were matched to clinical data. Performance was defined as %BG within glycemic bands and BG measurement frequency. Safety was defined as the incidence of severe (number patients with BG<40mg/dL) and moderate (%BG<72mg/dL) hypoglycemia. Clinical data from SPRINT is also compared. Results: Clinical SPRINT performance data matched re-simulated SPRINT with 86% vs. 86% BG in 80-145mg/dL, 2.00% vs. 2.07% BG above 180mg/dL and 7.83% vs. 7.29% BG below 72mg/dL, with 14 measurements (over 8 patients) of BG<40mg/dL. Yale results were 83.5%, 3.20%, 5.18%, with 6 severe hypoglycemic patients, using 37,961 measurements (23.0/day). Glucontrol had 75.2%, 3.70%, 9.45%, 52 cases and 26,199 measurements (15.8/day). Braithwaite had 84.2%, 3.00%, 4.22%, 19 cases and 24,396 measurements (14.8/day). The STAR (Stochastic TARgeted) model-based method had 90.6%, 1.67%, 1.33%, 5 cases and 20,591 measurements (12.3/day). Conclusions: Virtual trials provided an effective comparison across protocols with different target bands/values and different clinical cohorts. The model-based STAR protocol provided the best management of patient variability yielding the best performance and safety

Online change detection for energy-efficient mobilec crowdsensing

Mobile crowdsensing is power hungry since it requires continuously and simultaneously sensing, processing and uploading fused data from various sensor types including motion sensors and environment sensors. Realizing that being able to pinpoint change points of contexts enables energy-efficient mobile crowdsensing, we modify histogram-based techniques to efficiently detect changes, which has less computational complexity and performs better than the conventional techniques. To evaluate our proposed technique, we conducted experiments on real audio databases comprising 200 sound tracks. We also compare our change detection with multivariate normal distribution and one-class support vector machine. The results show that our proposed technique is more practical for mobile crowdsensing. For example, we show that it is possible to save 80% resource compared to standard continuous sensing while remaining detection sensitivity above 95%. This work enables energy-efficient mobile crowdsensing applications by adapting to contexts

Structure, ultrastructure et analyses physico-chimiques des tissus durs dentaires des vipéridés

The present study, using classical microscopy, scanning electron microscopy, transmission electron microscopy, X-ray diffraction, infra-red spectroscopy, has shown the dental hard tissues of the fangs of Viperidae (poisonous serpents with terrestrial or semi-aquatic habits) to be constituted of:a calcified outer layer, 0.4 µm thick, made of very small needle-like crystals, randomly distributed. The calcified outer layer contains organic invaginations inducing pores at the surface and many collagen fibres uncompletely mineralized, which may suggest enameloid.a calcified inner layer, in the wall of the poison canal. The calcified inner layer, 0.6 µm thick, is constituted of very small crystals, which are parallel to each other and perpendicular to the calcified outer layer. It might be the inner layer of enameloid.an orthodentine, whose tubules present a special lateral branching system resembling a fish-bone. The TEM data, which show the dentine to be constituted of very small ill-defined crystals and uncompletely mineralized collagen fibres are corroborated by chemical analyses which reveal a poorly mineralized apatite with high carbonate content.Le présent travail, en microscopie photonique, microradiographie, microscopie électronique à balayage, microscopie électronique à transmission, diffraction X et spectroscopie infra-rouge, a permis de mettre en évidence, dans les tissus dentaires minéralisés des crochets des Vipéridés (serpents venimeux de moeurs terrestres ou semi-aquatiques):une couche externe calcifiée (CEC), d’une épaisseur de 0,4 µm environ, constituée de très petits cristaux aciculaires, sans orientation préférentielle. La CEC renferme des invaginations organiques, pouvant aboutir à un pore en surface et une proportion importante de structures fibrillaires de nature collagénique évoquant un émailoïde.une couche interne calcifiée, au niveau de la paroi du canal à venin. La couche interne calcifiée, d’une épaisseur de 0,6 µm environ, est constituée de très petits cristaux aciculaires parallèles entre eux et perpendiculaires à la couche externe calcifiée. Elle renferme également des fibres de collagène incomplètement minéralisées. Il pourrait s’agir d’un émailoïde interne.une orthodentine, dont les tubuli présentent un système de ramifications latérales donnant une image en arête de poisson. Les données de la MET, montrant que la dentine des crochets est composée de très petits cristaux aciculaires mal définis et de fibres de collagène incomplètement minéralisées sont confirmées par les analyses chimiques indiquant que le minéral est une apatite de faible cristallinité, fortement carbonatée
