We previously showed that low levels of day-14 CD3 T and NK (CD56) cells donor chimerism predicted graft rejection, whereas high levels of day-28 CD3 T-cell donor chimerism predicted acute graft-versus-host disease (GVHD) after HCT with nonmyeloablative conditioning. Here we investigate whether assessing chimerism levels among CD4 T cells and CD8 T cells, and also the absolute number of lymphocyte subsets of donor and host origins, would lend greater precision to our initial observations. We analyzed data from 157 patients receiving HCT after conditioning with 2 Gy TBI +/− fludarabine as treatment for AML (n= 22), ALL (n= 4), CML (n= 13), CLL (n= 19), MDS (n= 26), MM (n= 24), NHL (n= 30), HD (n= 14), RCC (n= 4), and WASP deficiency (n= 1). Postgrafting immunosuppression included MMF and CSP. A total of 97 patients received grafts from HLA-identical siblings, and 60 patients received grafts from HLA-matched unrelated donors. Lymphocyte subsets were isolated from peripheral blood by flow cytometry on days 14, 28, and 42. The proportion of cells of donor origin (chimerism levels) were assessed by VNTR-PCR and quantified by phosphor imaging. Eighteen patients (11%) had graft rejection. Day-14 donor chimerism levels< 50% among CD3 T (P =.0007), CD4 T (P =.03), and NK cells (P =.003) but not CD8 T cells predicted graft rejection. High absolute numbers of CD3 T (P =.002) and NK cells (P= .002) of host origin on day 14 were each associated with increased risks of graft rejection when treated as continuous linear variables. Grades 2, 3, and 4 acute GVHD were seen in 40%, 9%, and 5% of patients, respectively. High donor chimerism levels on day 14 among CD3 T (P= .02), CD4 T (P =.03), and CD8 T cells (P =.02) but not NK cells were each associated with increased risks of grades 2–4 acute GVHD. High absolute numbers of CD4 T (P =.04) and CD8 T cells (P =.04) of donor origin on days 14–42 were each associated with increased risks of grade 2–4 acute GVHD when treated as continuous linear variables, whereas high donor CD3 T (P= .002), CD8 T (P= .006), and NK cell (P= .002) chimerism levels from days 14–42 were associated with decreased risks of relapse. No statistically significant correlations between absolute numbers of donor cells and risks of relapse were found. These data suggest that assessing CD3, CD4, CD8, and NK cell donor chimerism levels and determining absolute numbers of CD3 and NK cells of host and donor origins are useful for predicting HCT outcomes after nonmyeloablative conditioning.

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 ▲]

The paper deals with an application of Artificial Neural Networks (ANNs) to predict the geometry of hot forged pieces after cooling. Different ANNs have been considered and evaluated; then a network with two hidden layers has been set up. Training and testing data have been obtained through calibrated numerical simulations of the cooling phase carried out with a finite element (F.E.) code. The good agreement between predicted and numerical results confirms the possibility of using well-trained neural network to foresee final dimensions of pieces after hot forging operations. [less ▲]

The aim of this study was to estimate sedimentation rates in floodplains and to investigate lateral channel migrations over the last centuries. Considering the difficulties in determining these parameters using traditional dating methods, we have used different kinds of slag rejected from former metal works. In the Ardenne region (southern part of Belgium), at the end of 14th century, iron factories moved near to rivers in order to take advantage of the hydraulic energy. At the same time, large quantities of slag produced in primitive blast furnaces were piled onto the floodplains, often very close to rivers. Consequently, microslag could be carried away either during floods or by lateral erosion to be deposited on the floodplains downstream. In order to use slag as a stratigraphical tracer, we located slag waste sites along rivers and we dated the periods of furnace activity from historical studies. Afterwards, we measured slag concentrations in the alluvium and we studied their evolutions in different borings. These results allowed us to reconstruct the appearance of the floodplain at the inception of the metal works and to estimate lateral channel mobility over several centuries. Moreover, different kind of tephra and 14C dating have been used in order to date the deposits that have been established before the settlement of metallurgy. [less ▲]

Whereas human studies keep reporting evidence that acetaldehyde accumulation prevents alcohol drinking and alcoholism, animal studies support a rewarding rather than aversive role for acetaldehyde. In recent years, the reinforcing properties of acetaldehyde were demonstrated in various rodent strains and using different experimental methods. These results led to the hypothesis that acetaldehyde might be involved in the addictive properties of alcohol. The most recent experimental studies suggest that the apparent discrepancies between animal and human studies might be due to the localization of acetaldehyde accumulation. Whereas peripheral acetaldehyde accumulation leads to adverse reactions and prevents alcohol drinking, brain acetaldehyde is believed to be primarily reinforcing in both rodents and humans. In addition to its possible role in the reinforcing properties of alcohol, there is also evidence that acetaldehyde is involved in many other behavioral effects of ethanol. This presentation reviews the latest results about the behavioral properties of acetaldehyde. In both CD1 and C57BL/6J mice, acetaldehyde induces locomotor depressant, sedative and amnesic effects. These effects are observed when acetaldehyde is administered either in the periphery or directly into the brain. In contrast to previous studies in rats, we found no evidence of the stimulant effects of acetaldehyde over a wide range of doses, whether injected in the periphery or administered intracerebroventricularly. Additional studies with cyanamide, an aldehyde dehydrogenase inhibitor leading to peripheral and central acetaldehyde accumulations after ethanol administration, also confirm the role of acetaldehyde in the locomotor depressant, sedative and amnesic effects of ethanol. However, a key issue remains to be addressed in order to demonstrate the role of acetaldehyde in alcohol abuse. To date, it remains uncertain whether pharmacologically relevant acetaldehyde concentrations are formed in the brain after alcohol consumption in vivo. [less ▲]

In the present study, deep drawing simulations were investigated using a recently developed mixed type finite element (FE): the BWD3D. The main formulation of the element is described, with particular focus on the shear locking treatment. Two hardening models used in the presented simulations are described: the isotropic Swift’s model and the physically based microstructural Teodosiu and Hu model. Finally, deep drawing results, in terms of earing profile, are compared to experiment. Special attention is paid to the effects of texture evolution and hardening models; the method used to implement Teodosiu and Hu hardening model is also discussed. [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.

Human beings have continuously attempted to adapt their environment to their needs. However, many natural phenomena still remain challenging to control and the populations must undergo sometimes heavily damaging consequences. It is consequently essential to study these phenomena in order to assess their potential hazards. In particular, the scope of the present paper focus on floods. The intense floods met these last years showed the importance of this phenomenon as well as its many devastating effects. Thanks to recent important breakthroughs, both in the field of conceptual and numerical modelling of complex flows and in the calculation power of computers, it is henceforth possible to study the effects of potential floods on the basis of numerical simulations, with an accuracy never reached beforehand. The Laboratory of Applied Hydrodynamics and Hydraulic Constructions (HACH) of the University of Liege has always made this kind of study one of its core competencies, thanks to • the development of modern and powerful modelling tools (quasi-three dimensional software for flow simulation by finite volume), • the use of a broad range of data enabling a proper representation of the studied fields (topography, occupation of the ground...) • the systematic validation of simulation results. These tools are currently intensively used within the framework of a general study of the flood-prone zones of the Walloon area of Belgium, which corresponds to more than 800 km of rivers. [less ▲]

We consider random matrix models for the thermodynamic competition between chiral symmetry breaking and diquark condensation in QCD at finite temperature and finite baryon density. The models produce mean field phase diagrams whose topology depends solely on the global symmetries of the theory. We discuss the block structure of the interactions that is imposed by chiral, spin, and color degrees of freedom and comment on the treatment of density and temperature effects. Extension of the coupling parameters to a larger class of theories allows us to investigate the robustness of the phase topology with respect to variations in the dynamics of the interactions. We briefly study the phase structure as a function of coupling parameters and the number of colors. [less ▲]

Many CAD tools already allow to create and manipulate directly ideas in a digital way. However, designers still use the pen and paper technique during the early design phase of their projects. Indeed, existing CAD tools con-straint the creative work. There is a need for a sponta-neous human computer interaction in design computing. In order to answer to this need, we develop an integrated aided design tool based on an Virtual Desktop. The de-signer sits in front of a classical desktop where s/he can create and manipulate drawings and generated models. The paper relates the observations made from an ex-periment about the use of the Virtual Desktop by a de-signer. That experiment demonstrates that the immersive aspect of our system interface modifies the relation exist-ing between the designer and his/her model and, this way, its generates a new type of augmented interaction.

Single-point incremental forming (SPIF) is a sheet metal forming technique that has gained particular interest in rapid prototyping and small volume production. The study of the underlying forming mechanisms is supported by new developments in finite element simulations and experimental full field strain measurements. This article aims to describe the possibilities and difficulties encountered during validation of finite element predictions of the incremental forming process. The drawing of a straight line into a metal plate was selected as a first test case for this kind of validation. Results of both finite element simulation and experimental work will be discussed.

For an underground storage of nuclear waste, it is necessary to minimize the excavation damage zone (EDZ) that could be a higher permeability zone. This paper deals with the FE modelling of the EDZ extent during tunnelling. A Drucker – Prager law with cohesion strain softening is used. Results show a shear banding around the excavation. Its extent and the tunnel convergence are highly dependent on the hydraulic boundary condition within the tunnel (imposed pore pressure – suction or unilateral flow condition). [less ▲]

In developmental neuropsychology, attentional and executive impairments are commonly reported following acquired neurological/developmental disorders such as Traumatic Brain Injury (TBI), epilepsy, ADHD… Unfortunately, most of attentional tests used in child neuropsychology were originally developed for adults and are of limited interest for children (notably because of their lack of attractiveness or because they require some non-developed skills). From a cognitive perspective, it is therefore often difficult to interpret the results obtained with such tools in children. The aim of this study was to develop assessment tasks of attentional/executive functioning which are more attractive (by using colored/familiar stimuli) and more theoretically relevant for young children. The tasks are based on Posner’s attentional model, which includes selective and sustained attention, attentional shifting and cognitive inhibition. Eighty children aged from 5 to 11 with no developmental/neurological deficits were administered tasks assessing visual selective attention (selecting a specific character among distractors), sustained attention (crossing dinosaurs in 5 minutes), flexibility (shifting between name and colour of stimuli), and inhibition (naming the real colour of a red banana or a yellow strawberry). Results confirmed the interest of these tasks in the assessment of attentional functioning in children, thanks to both their limited duration of administration and the stimuli’s attractiveness. Furthermore, results showed that tasks are sensitive to attentional development from 5 to 11 years old (p < .05). Finally, a preliminary study showed that some tasks can be particularly sensitive to attentional disorders in a clinical population of TBI children. [less ▲]

The histaminergic neurotransmission is involved in many biological functions, including the modulation of arousal, fluid balance, food intake, reinforcement and learning. Recently, the results of several studies have also suggested that the central histaminergic system, and particularly the H3 receptors, plays a role in drug addiction. For example, in animal experiments, the administration of H3 agonists and antagonists modulate the self-administration of various drugs including cocaine, amphetamine and alcohol. In the present studies, we used the locomotor stimulant effects of drugs as an index of their abuse potential (most of addictive drugs stimulate locomotor activity, at least at some doses, and this effect is often considered as an intrinsic feature of drug addiction). In two independent experiments, we tested the effects of thioperamide, a histamine H3 antagonist/inverse agonist, on the locomotor stimulant effects of cocaine and ethanol. Our results show that thioperamide modulates the locomotor stimulant effects of both cocaine and ethanol. However, this modulatory effect was surprisingly opposite in direction depending upon the tested drug. Whereas thioperamide potentiated the locomotor stimulant effect of cocaine, it prevented the hyperactivity induced by 2 g/kg ethanol in mice. In the brain, H3 receptors is both a histamine autoreceptor modulating the synaptic release of histamine and a heteroreceptor that modulates the release of other neurotransmitters such as dopamine, acetylcholine and GABA. It is therefore likely that the modulatory action of thioperamide on cocaine and ethanol stimulant effects involves different neurotransmitter system. This conclusion is supported by our preliminary results on knock-out mice genetically devoid of histamine. In such knock-out mice, ethanol retains its stimulant properties, suggesting that histamine release is not involved in this effect. In contrast, these knock-out mice showed a reduced cocaine-induced hyperactivity, indicating that histamine release play a significant role in the stimulant effect of cocaine. [less ▲]

This paper describes a methodology for the study of long-term network planning under uncertainties. In this approach the major external uncertainties during the planning horizon are modelled as macro-scenarios at different future time instants. The random nature of actual operating conditions is taken into account by using a probabilistic model of micro-scenarios based on past statistics. MonteCarlo simulations are used to generate and simulate a specified number of scenarios. Data mining techniques are then applied to the simulations results collected in a database, so as to extract information and to rank scenarios and network reinforcements according to different performance criteria. The paper describes the application of this approach on a real transmission planning problem faced by the Belgian transmission system operator. [less ▲]

An abstract numeration system is a triple S = (L, Sigma, <) where (Z, <) is a totally ordered alphabet and L a regular language over Z; the associated numeration is defined as follows: by enumerating the words of the regular language L over Z with respect to the induced genealogical ordering, one obtains a one-to-one correspondence between N and L. Furthermore, when the language L is assumed to be exponential, real numbers can also be expanded. The aim of the present paper is to associate with S a self-replicating multiple tiling of athe space, under the following assumption: the adjacency matrix of the trimmed minimal automaton recognizing L is primitive with a dominant eigenvalue being a Pisot unit. This construction generalizes the classical constructions performed for Rauzy fractals associated with Pisot substitutions [16], and for central tiles associated with a Pisot beta-numeration [23].

This research developed at University of Liege aims to optimize the complete semi-continuous casting process at LBP Company, a producer of copper-nickel alloys (or cupro-nickels). The process consists in vertical casting of 7m long ingots. Some problems recurrently occur during casting process: formation of oscillations (wave length of about 500 mm), unsuitable concave cross-sections or internal cracks. In order to reduce the occurrence of such defects and to better understand their formation, we have been asked to develop a finite element model. The research focuses on two main topics: identification of material properties through laboratory tests and literature survey and the development of the numerical tool. The laboratory tests provide thermal and mechanical properties of the ingot and the mould, as well as heat transfer coefficients between the ingot and its surroundings (mould, air and water). These parameters are required for the numerical simulations of the process. In the second part of the research, numerical calculations have been performed using finite element method. Two types of 2D models have already been studied: horizontal slice and vertical slice. This first choice has been guided by the high coupling between thermal and mechanical aspects of the problem, leading to highly complex systems of equations and subsequent long CPU times. However, due to the limitations of such 2D models, a 3D formulation has then been considered and it is still in progress. [less ▲]
