We address the question to what extent polyhedral knowledge about individual knapsack constraints suffices or lacks to describe the convex hull of the binary solutions to their intersection. It turns out that the sign patterns of the weight vectors are responsible for the types of combi- natorial valid inequalities appearing in the description of the convex hull of the intersection. In particular, we introduce the notion of an incom- plete set inequality which is based on a combinatorial principle for the intersection of two knapsacks. We outline schemes to compute nontrivial bounds for the strength of such inequalities w.r.t. the intersection of the convex hulls of the initial knapsacks. An extension of the inequalities to the mixed case is also given. This opens up the possibility to use the inequalities in an arbitrary simplex tableau. [less ▲]

Recently, our phylogenetic study revealed that the Bovine herpesvirus 4 (BoHV 4) Bo17 gene has been acquired from an ancestor of the African buffalo around 1.5 million years ago, implying that cattle subsequently acquired BoHV 4 by cross species transmission (Markine-Goriaynoff et al., 2003, 77:1784-1792). In the present study, we pursued our investigation on the origin and the evolution of BoHV 4. Firstly, with the goal in mind to further precise the origin of the Bo17 gene, the C2GnT M gene sequence was determined for each subspecies of African buffalo and for three types of Asian buffalo. Phylogenetic analyses of these new sequences further supported our conclusion that the Bo17 gene has been acquired from an ancestor of the African buffalo, possibly of the Syncerus caffer caffer subspecies from East-Africa origin. Secondly, to investigate the phylogeographical relationships among BoHV-4 strains isolated from four different continents, phylogenetic analyses were performed based on six different regions distributed throughout the genome. Analyses of these regions revealed a clear correlation between the phylogenetic relationships among BoHV-4 strains and their geographical origin, leading to the concept of BoHV-4 geographical clades. These analyses also demonstrated that since the acquisition of the Bo17 gene, recombination events occurred at different time in the past between ancestors of actual geographical clades. These recombinations provided an opportunity to learn how after acquisition of the Bo17 gene in Africa around 1.5 million years ago, BoHV-4 has spread to the world to form phylogenetically related geographical clades.

MARE gathers 24 laboratories of the Faculties of Science, Applied Science, Law and Veterinary Medicine. It integrates complementary disciplines of Oceanology through both pluridisciplinary field works and modeling. Major research themes of MARE are: 1) The detection and prediction of changes in coastal ecosystems integrating data collection, the development of statistical tools and 3D interdisciplinary models used conjointly with specific diagnostic tools tailored to management purposes; 2) The study of the CO2 dynamics in order to budget fluxes in major coastal areas and the Southern Ocean, through data collection, satellite imagery and modeling studies; 3) The dynamic and diversity of the Ocean Pelagic Ecosystem; 4) Biodiversity and taxonomic studies in different coastal and deep-sea areas; 5) Study of marine trophic webs using stable carbon and nitrogen isotopes; 6) Ecotoxicology and Ecophysiology: study of the effects of pollutants on marine organisms including marine mammals and investigations on genetic diversity, pathology and causes of death of marine mammals and seabirds; 7) Ecology of macrophytes systems and of benthic algae; 8) Sediments studies (e.g. sediment transport, sediment structure analysis, benthic habitats characterization and diversity); 9) Reconstruction of paleocirculations using isotope analysis (Nd, Pb); 10) Study of coastal evolution and management. This includes the study of coastal geomorphology using remote sensing data and coastal engineering. Moreover, MARE researchers have access to the research station STARESO in Corsica (http://www.stareso.com/), and to the Belgian R.V. Belgica, which operates in the North Sea and adjacent areas (http://www.mumm.ac.be/EN/Monitoring/Belgica/). Finally, the MARE centre supports the extant set of second and third cycle Teachings (master in Oceanography; http://www.ulg.ac/oceanbio/, DEA in Oceanology, European DEA in Marine Environment Modeling) - unique in the French-speaking Community of Belgium -, of a Doctoral School, and of international Conferences and Colloquia (The International Liège Colloquium on Ocean Dynamics and associated Symposia).

Prion pathogenesis following oral exposure is thought to involve gut-associated lymphoid tissue, which includes Peyer’s patches (PP). Before neuroinvasion, early accumulation of infectious prion protein (PrPsc) takes place on follicular dendritic cells (FDC) which are resident cells in germinal centres. The strain, the infection pathway and the lesions in the central nervous system are similar between bovine spongiform encephalopathy (BSE) and variant Creutzfeldt Jakob diseases. But in BSE, the agent tropism differs from lymphoid organs. Only bovine ileal PP are infectious. In order to study the replication and the possible ways of neuroinvasion of PrPsc in bovine PP, we studies the expression of cellular prion protein (PrPc), necessary for PrPsc accumulation, and compared the innervation of germinal centres related to FDC on ileal and jejunal PP of cows and calves. We performed classical immunoperoxydase staining and double immunofluorescence staining analyzed with a confocal microscopy. Differences in the innervation of germinal centres and expression of PrPc were evident. More contacts between FDC and nerve fibres are observed in calves PP. PrPc expression, carried out with different anti-PrPc antibodies, highlighted a heterogeneous labelling between calves and cows PP. Such results permit us to show that the innervation of PP is a dynamic process which could influence the first way of neuroinvasion in prion diseases. Moreover differences in the affinity of some antibody for PrPc allow us to postulate that PrPc glycoforms differ with age of bovines and thus could interfere with PrPsc tropism. [less ▲]

In this paper, we present a new simulation tool for process engineers. During process design phases, several aspects of machining have to be taken into account. Classical CAD/CAM suites still lack some crucial issues. The goal of the developed tool is to predict the geometric errors of machined surfaces. For classical applications of the automotive domain, form errors are mainly due to the machined part and clamping system flexibility. They are modeled thanks to the FE method. The major peculiarity of the adopted model is to apply numerous load cases. To achieve a low computational coast, we have combined the SAMCEF superelement feature and a specific code to solve the reduced system. This original scheme allows solving efficiently large industrial applications. [less ▲]

In this paper, we propose a method for sleep apnea and hypopnea detection by analyzing the mandibular movements recorded during sleep. This signal, highly correlated with the esophageal pressure during apnea or hypopnea, is a good marker of respiratory efforts. The respiratory efforts and their background activity are used to detect salient mandibular movements related to sleep apnea and hypopnea, to delineate and to recognize episodes of sleep apnea and hypopnea. The method presented may be extended to others breathing disorders such as Respiratory Efforts Related Arousals (RERA). [less ▲]

Two groups (A and B) of 6 piglets, weaned at 21 days (D0), received ad libitum the same diet during three weeks. The piglets of group A were not submitted to a colostrum supplementation while those of the group B received daily and orally 5 g of bovine colostrum. Each week, piglets were weighed and blood was taken on each one of them. One piglet of each group was sacrified on D0 and the rest of the animals on D21. Mesenteric lymph nodes (ML), iléal Peyer patches (iPP), jejunum and spleen biopsies were taken on each piglet before death. The haematological values and the intestinal histo-morphological data between the two groups were not significantly different, but FACS analyses on the lymphocytes in the biopsies and the determination of stimulation index suggested a significative effect of colostrum on the lymphocytes populations, with, in the ML, an increase of the LB population (14 % vs 28 %, P < 0,05) and, in the iPP, a reduction of the LB's (54,99 % vs 8,44 %, P < 0,01) with an increase of the LT cells (16,87 % vs 72,00 %, P < 0,001). An increase of the lymphocyte stimulation index from piglets receiving colostrum was observed the second day of in vitro stimulation with colostrum. In brief, the answer of the immunity system to bovine colostrum seems to be restricted to the intestinal immunity system and is characterised by an activation, a multiplication and a modification of the lymphocytes ratios.

Parmi les canaux ioniques impliqués dans le contrôle de l'activité neuronale, les canaux potassiques calcium-dépendants de basse conductance, dénommés canaux SK, constituent une cible thérapeutique intéressante. En effet, ils sous-tendent la posthyperpolarisation ("AfterHyperPolarization") de durée moyenne (mAHP) qui limite l'excitabilité de divers types de neurones du système nerveux central (SNC). Leur blocage pourrait être ainsi bénéfique dans le traitement de divers troubles du SNC comme la maladie de Parkinson, la dépression ou encore les désordres cognitifs. Jusqu'à présent, le bloqueur de référence des canaux SK est l’apamine, un octadécapeptide issu du venin d'abeille. En revanche, peu de composés synthétiques avec une affinité proche de celle de l’apamine ont été caractérisés. Dans ce contexte, nous avons développé un modèle pharmacophorique de bloqueurs non-sélectifs qui a révélé, entre autres, une distance optimale de 5.6 Å entre deux charges positives. Ce modèle sera le point de départ de futures investigations dans le développement de nouveaux bloqueurs des canaux SK. [less ▲]

Synthetic radial velocities for a population of 2300+ known spectroscopic binaries are generated according to the present scanning law. The effect of the distribution of the observations and of the noise on the orbit fitting is investigated. According to our preliminary results short periods, below one day, will be hard to identify among the many aliases, even in the absence of noise. Requirements in terms of computing power for this shell task are estimated in conjunction with the adopted algorithm for the period search part of the orbit reconstruction. These results are for binaries detected in the Radial Velocity Spectrometer only. [less ▲]

Gaia will provide astrometric and photometric observations for about 500 000 quasars distributed over the whole sky. The latter would constitute an isotropic grid of fixed sources perfectly suited to determine the referential frame. However, they must first be properly identified among stars, whose population is about 2000 times larger. Using broad and medium band photometry, we first compare the efficiency of two analysis methods (Ï 2 fitting and Artificial Neural Networks, ANNs) to produce the QSO catalogue with the lowest amount of contamination by stars. We then investigate whether the Gaia photometry could also provide precise values of the QSO astrophysical parameters (APs, like the redshift, the continuum slope, the emission line strength and possibly the extinction). To reach that purpose, we also compare the performances of the Spectral Principal Component Analysis (SPCA) with those of the Ï 2 fitting and ANN analysis. [less ▲]

The Ninth Catalogue of Spectroscopic Binary Orbits1 and the Hipparcos Intermediate Astrometric Data (IAD) are used to retrieve astrometric binaries from the Hipparcos data. It is found that basically all (non-SB2) systems with periods larger than about 100 d, and parallaxes larger than 5-10 mas exhibit an astrometric orbital motion which can be extracted from the IAD. The lessons learned from this kind of approach will be very valuable for the design of the Gaia reduction pipeline. [less ▲]

Atypical myopathy (AM) in grazing horses is a frequently fatal condition that has been reported in several European countries. In Belgium, since autumn 2000, AM was confirmed in 39 equids based on characteristic histological lesions in postural and respiratory muscles. This study describes the history, clinical signs and biochemical changes associated with AM in these confirmed cases. [less ▲]

The Non-Linear Resonant Decay Method is an approach for the identification of non-linear systems with large numbers of degrees of freedom. The identified non-linear model is expressed in linear modal space and comprises the modal model of the underlying linear system with additional terms representing the non-linear behaviour. Potentially, a large number of these non-linear terms will exist but not all of them will be significant. The problem of deciding which and how many terms are required for an accurate identification has previously been addressed using the Forward Selection and Backward Elimination techniques. In this paper, a Genetic Algorithm optimisation is proposed as an alternative to those methods. A simulated 5-DOF lumped parameter non-linear system is used to demonstrate the proposed optimisation. The use of separate data sets for the identification and validation of the modal model is also investigated. It is found that the Genetic Algorithm approach yields significantly better results than the Backward Elimination and Forward Selection algorithms in many cases. [less ▲]

The shoot apical meristem (SAM) of Sinapis alba can be switched from vegetative to reproductive fate by exposure of 2-month old plants to a single long day (LD). Floral transition then occurs in good synchrony within a population, and a number of biochemical, cellular, and morphological changes have been described. Our aim is to integrate gene expression patterns into this timing. We report here the analysis of SaLFY, orthologous to the floral meristem identity gene LEAFY of Arabidopsis. Materials and Methods: Plants of Sinapis were grown in 8-h shorts days for two months before being induced to flower by one 22-h LD. Shoot apices were harvested 24, 32, 40, 48, 56 and 80h after start of the LD, and prepared for in situ hybridization (Melzer et al., 1999). Results and Conclusions: As expected, the expression of SaLFY was very strong in flower primordia. More surprisingly, SaLFY was expressed well before the initiation of flowers. First, a strong signal was detected in the tip of young leaf primordia of vegetative plants. Secondly, SaLFY was transiently expressed in the SAM of induced plants, from 32h after the start of the LD, when cell proliferation increased. The signal formed, in transverse sections, a discontinuous ring with activation where last leaves were to be initiated. Interestingly, this activation in the SAM matched in time and space early growth changes previously described during the transition to flowering, namely an increase of leaf primordia growth and an acceleration of last leaf initiation (Bernier, 1997), suggesting that SaLFY may have dual functions in fate specification during the floral transition of the SAM.

Memory for times of past events depends on direct impressions of the temporal “distances” of the events in the past and the reconstruction of temporal “locations. Two studies shed light on the possible neurological basis of location-based processes. In an ERP study, adults performed tasks thought to bias subjects to use distance or location processes. Late frontal activity was specifically linked to location-based processes. In another study using the same tasks, aging was found to disrupt location-based processes more than distance-based processes. Age-related differences in the use of location-based processes were mediated by speed of processing and by working-memory capacities. [less ▲]

We present a new 3D full-frame profilometer based on structured laser light projection method. This device takes advantage of the polarization states splitting technique for producing and shifting multiple sinusoidal Young’s interference patterns that are projected on the inspected surface. The principle of the technique is presented and we discuss the advantages of monochromatic light projection method as a mean to overcome ambient lighting for in-situ measurement. Some results that we obtained on objects from the Egyptian Department of the British Museum are presented to demonstrate that 3D laser profilometry is a worthwhile technique for epigraphic investigations where naked-eye inspections fail.
