In this paper, we propose a technique based on 3D information (also called depth or range) for the detection of humans. First, a background subtraction technique operates to detect the silhouettes of humans and objects moving in the scene. Then, a machine learning algorithm is used to predict if a silhouette annotated with depth matches a human silhouette or not. The complete method is designed to cope with defects introduced during the segmentation step. Results, obtained on computer generated data, show that 3D depth data is a valuable information for detecting humans in that it improves over techniques based on binary silhouettes. In our experiments, we have reached an accuracy of 99.9% thanks to the depth information. [less ▲]

OBJECTIVE: In this study, we have evaluated the organ procurement and transplantation activity from donors after cardiac death (DCD) at our institution over an 8-year period. Our aim was to determine whether this program influenced transplantation programs, or donation after brain death (DBD) activity. METHODS: We prospectively collected our procurement and transplantation statistics in a database for retrospective review. RESULTS: We observed an increasing trend in potential and actual DCD number. The mean conversion rate turning potential into effective donors was 58.1%. DCD accounted for 16.6% of the deceased donor (DD) pool over 8 years. The mean age for effective DCD donors was 53.9 years (range, 3-79). Among the effective donors, 63.3% (n = 31) came from the transplant center and 36.7% (n = 18) were referred from collaborative hospitals. All donors were Maastricht III category. The number of kidney and liver transplants using DCD sources tended to increase. DCD kidney transplants represented 10.8% of the DD kidney pool and DCD liver transplants made up 13.9% of the DD liver pool over 8 years. The DBD program activity increased in the same time period. In 2009, 17 DCD and 33 DBD procurements were performed in a region with a little >1 million inhabitants. CONCLUSION: The establishment of a DCD program in our institution enlarged the donor pool and did not compromise the development of the DBD program. In our experience, DCD are a valuable source for abdominal organ transplantation. [less ▲]

The objective of this technical note is to explore the applicability of nonlinear system identification techniques to spacecraft structures. To this end, numerical experiments carried out using the finite element model of the SmallSat spacecraft are used, without, however, having access to the model itself. The constraints imposed by the considered techniques for breadboard testing are also highlighted. [less ▲]

Un logiciel appelé EOL-OS a été développé dans le cadre des WP4 et 5 du projet « Windsteel : développement de solutions en acier pour la construction éolienne ». Cet outil informatique est essentiellement destiné au dimensionnement et à l’optimisation structurelle des éoliennes offshores de type monopile en acier. Toutefois, lors des développements effectués dans le courant du second semestre de l’année 2010, son application aux éoliennes onshore en acier a été rendue également possible. Ce document s’inscrit dans la continuité du rapport technique semestriel S1 de 2010. Il est laissé au lecteur le soin de se référer à ce dernier pour ce qui concerne la nomenclature utilisée pour décrire les structures étudiées ainsi que le détail des modules implémentés au terme des 6 premiers mois de 2010. La première partie du présent rapport concerne les développements effectués sur le logiciel EOL-OS et se focalise en particulier sur les modules implémentés dans le courant du semestre S2 de 2010. La seconde partie traite des résultats d’optimisation obtenus au terme des différentes simulations et tirent des conclusions générales sur le dimensionnement des structures support des éoliennes.

Convergence analysis of consensus algorithms is revisited in the light of the Hilbert distance. The Lyapunov function used in the early analysis by Tsitsiklis is shown to be the Hilbert distance to consensus in log coordinates. Birkhoff theorem, which proves contraction of the Hilbert metric for any positive homogeneous monotone map, provides an early yet general convergence result for consensus algorithms. Because Birkhoff theorem holds in arbitrary cones, we extend consensus algorithms to the cone of positive definite matrices. The proposed generalization finds applications in the convergence analysis of quantum stochastic maps, which are a generalization of stochastic maps to non-commutative probability spaces. [less ▲]

Judah Folkman was the first in 1971 to observe and report that cancer growth and dissemination were dependent on angiogenesis - the formation of new blood vessels from pre-existing vasculature. For almost 40 years, this concept has inspired generations of researchers to identify anti-angiogenic molecules that could be used therapeutically to stop blood vessels formation and starve tumors of nutrients and oxygen. Tumor angiogenesis requires complex cellular and molecular interactions between endothelial and cancer cells. In response to external stimuli such as hypoxia, cancer cells secrete pro-angiogenic factors into the extracellular matrix that activate the surrounding endothelial cells to proliferate, migrate and form new blood vessels. So, vascularization of malignant lesions depends on the expression of specific genes in both endothelial and tumor cells and accumulating evidences shows that several members of the histone deacetylase (HDAC) family play key roles in the regulation of these genes. Indeed, numerous in vitro and in vivo studies demonstrated that inhibitors of HDAC modulate angiogenic gene expression in both endothelial and cancer cells and disturb the delicate and complex balance between the collective action of pro-angiogenic factors and angiogenesis inhibitors. Thus, HDAC are currently recognized as promising targets for the development of anti-cancer drugs. This review is an effort to present and discuss the role, functions and mechanisms of action of HDAC during tumor-driven angiogenesis as well as a brief summary of the clinical status of the main HDAC inhibitors (HDACi) currently under development in cancer therapy.

This paper proposes simple feedback loops, inspired from extremum-seeking, that use the photon emission times of a single quantum system following quantum Monte-Carlo trajectories in order to lock in real time a probe frequency to the system’s transition frequency. Two specific settings are addressed: a 3-level system coupling one ground to two excited states (one highly unstable and one metastable) and a 3-level system coupling one excited to two ground states (both metastable). Analytical proofs and simulations show the accurate and robust convergence of probe frequency to system-transition frequency in the two cases. [less ▲]

The hydrodynamic modelling system WOLF 2D enables to combine different hydrodynamic sub-models within one single computation domain. For instance, for the purpose of simulating flows in the vicinity of spillways, the following three hydrodynamic sub-models are interconnected: (i) a conventional “shallow-water” model, (ii) a suitable model for the simulation of the flow on the topographic step directly upstream of the spillway and (iii) a model able to accurately account for the bottom curvature near the spillway crest, along the spillway and at its bottom. In the latter model, based on curvilinear coordinates in the vertical plane, takes into consideration not only the bottom slope but also the bottom curvature in the vertical plane. As a result, the velocity profile along the water depth is generalized compared to the uniform profile usually assumed in the standard shallow-water equations and the pressure distribution is also modified as a function of the bottom curvature and is thus not purely hydrostatic but accounts for the effect of centrifugal forces. This extended mathematical model has been implemented within the modelling system WOLF 2D, based on a new finite volume scheme. Several validation examples and a real application demonstrate the accuracy and the practical applicability of the new model. [less ▲]

Background: Human cytomegalovirus (HCMV) has established itself as the most significant cause of congenital infection in the developed world. The objective of this research was prenatal identification of pregnant women at risk for developing active infection due to HCMV as well as to diagnose congenitally infected newborns. Methods: A diagnostic algorithm based on specific immunoglobulin G (IgG), IgM, and, IgG avidity was used to screen serum from 1131 pregnant women enrolled prospectively from 3 municipalities from Havana City, Cuba during 2007–2008. Qualitative multiplex nested PCR and quantitative real time-based PCR testing for HCMV DNA were performed on urine and saliva specimens from women detected with active infection and from their newborns. Results: Most women were seropositive to HCMV (92.7%), with 2.38% (27 women) having active infection. Primary infection was detected in 20 pregnant women (1.77%) while 7 patients (0.62%) had active nonprimary infection. HCMV DNA was detected in specimens from 9 of the 27 pregnant women by both PCR methods. HCMV congenital infection was diagnosed in 12 (1.06%) of the 26 live children born from 25 mothers with active infection, for a vertical transmission rate of 46.2%. Two fetal deaths were reported from 2 women with active infection; furthermore 2 newborns were symptomatic at birth and 2 showed sequelae during the follow-up done until 6 months age. Conclusions: Mothers with active infection during the pregnancy and with HCMV excretion had significant risks, RR = 1.16 and RR = 1.35, respectively, to have congenitally infected children. [less ▲]

Whereas it is obvious that the failure process can vary from one firm to another (Argenti, 1976; D'Aveni, 1989; Laitinen, 1991), to date, few researchers have worked on the detection of several explanatory failure patterns. In addition, none of the reviewed research really focuses on small firms while their failure is important and particular (Julien, 2005). Considering these observations and on the basis of two complementary statistical analyses (Thiétart, 2003), this article identifies, among a sample of 208 small Belgian distressed firms, a taxonomy of five explanatory business failure patterns, i.e. five homogeneous groups of small firms on the basis of the reasons for their failure. As the detection of the fundamental explanatory failure factors is the basis of failure prevention (Argenti, 1976), the identification of these patterns is of crucial importance for a better understanding and for a better prevention of this phenomenon [less ▲]
