This paper presents a ship impact analysis on lock gates. The case study is the downstream lock gates of the one of the four new locks planned within the framework of the “Seine-Escaut Est (SEE)” project in the Walloon Region of Belgium. The design and optimization process of the gate was realized with the LBR5 lock gate optimization software considering the cost and weight aspects of the structure. This method led to an optimized solution of the lock gate on which further studies were concentrated. After a brief overview of the state of art of ship impact analysis on lock gates, it was decided to perform a quasi-static analysis by finite elements. The non linear finite elements software FINELG was used to conduct a non linear numerical analysis of the effect of a boat impact on the gate. Several analyses were performed that highlighted the influence of the stiffener dimensions and the influence of the impact zone on the gate structural behavior submitted to impact. Finally, two different behaviors have been distinguished, a ductile one and a fragile one. The results showed the importance of the development of a global plastic mechanism, thanks to a ductile behavior, with the purpose of dissipating a large amount of energy. [less ▲]

INTRODUCTION: End-stage renal disease is a major public health problem in Viet Nam. A cooperative project between the University of Liege, Belgium, and the University of Medicine Pham Ngoc Thach, Ho Chi Minh City, Viet Nam, has permitted the establishment of an autonomous program of renal transplantation from living-related donors at the Peoples' Hospital No 115. The aim of this paper was to report the primary results of the project and to draw conclusions for the future. PATIENTS AND METHODS: From January 2004 to July 2008, we performed 33 living-related renal transplantations. Mean ages of donors and recipients were 31.8 +/- 9.5 and 41.6 +/- 13.5 years, respectively. Laparoscopic nephrectomy was performed in 6 donors. The immunosuppressive regimen consisted of three drugs associated with induction therapy using anti-interleukin-2 receptor monoclonal antibody. RESULTS: The 33 donors are in good health at follow-up. Four developed major intra- or postoperative hemorrhage necessitating transfusion, with a surgical re-exploration in 1 donor. Wound infection occurred in 2 donors. Posttransplant recipient and graft survivals at 1 versus 3 years were 82% and 73% versus 82% and 65%, respectively. Eight recipients presented 13 biopsy-proven acute rejection episodes that were reversible in 7, but 1 patient lost his graft due to an irreversible rejection. Two recipients developed cancer. CONCLUSIONS: These initial results have encouraged us to continue the program of renal transplantation from living-related donors. However, they also pointed out the need to develop other donor sources. [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.

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 ▲]

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 ▲]

In this study we report about the investigation of the spectral region 1.22-1.32 µm of the night side of Venus, observed by the VIRTIS instrument (Visible and InfraRed Spectral Imaging Spectrometer) on board the Venus Express spacecraft. This spectral region is characterized by the presence of the extensively studied (a1Δg – X3Σg-) (0,0) O2 nightglow band, the most intense emission observed on the night side of Venus. However, the comparison between data and synthetic spectra from the (0,0) band only, lacks a good match at wavelengths longer than 1.27 μm, especially in the region around 1.28-1.29 μm. The effects of temperature, CO2 and the (8,5) OH emission at 1.28 µm were investigated as a possible cause to the spectral disagreement, but they all are not enough to explain the observed difference. Instrumental effects were also excluded as possible cause of the mismatch. We found that the inclusion of the (1,1) band O2 emission in the synthetic spectra, originating from the upper vibrational level ν=1 of the (a1Δg – X3Σg-) transition centered at 1.28 μm, in addition to the (0,0), significantly improves the agreement between simulated spectra and observed data in the region at 1.28-1.29 μm. A synthetic spectrum, including the (0,0) and the (1,1) is produced and compared to 4 observed VIRTIS spectra, as an example. From the analyzed data, it results that the (1,1) band with an intensity ranging from the 8 to 15% of the (0,0) band is required to best reproduce the observed VIRTIS spectra. This corresponds to a (1,1) band intensity equal to 3.1-5.8 MR, in limb view, in agreement with the upper limit set by Connes et al., (1979), on their ground-based observations of the oxygen nightglow of Venus.

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 ▲]
