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.

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.

Two studies were conducted in order to assess the linearity and stationarity of the pharmacokinetics of tiludronate in horses. For each study, plasma concentrations of tiludronate were measured by HPLC-UV at regular intervals and noncompartmental analysis was performed. First, single intravenous administrations of 0.05 (group 1, n = 5), 0.1 (group 2, n = 5) and 0.2 mg/kg (group 3, n = 5) were performed in healthy male adult horses. A linear relationship between groups was found for C5min (C5min = 0.0726 + 11.8589 * dose) as well as for AUC0-inf (AUC0-inf = -0.632561 + 30.9649 * dose). Clearance ranged from 0.033 to 0.044 L/h/kg and was not significantly different between groups. MRT (h) were 3.96, 4.95 and 9.40 and VDss (L/kg) were 0.16, 0.19 and 0.28 for the 0.05, 0.1 and 0.2 mg/kg doses respectively. Second, 10 daily intravenous administrations at a dosage rate of 0.1 mg/kg were administered to 4 healthy horses. Plasma tiludronate concentrations were measured after the 1st and 10th dose as well as 8 hours after each dose. The mean plasma accumulation ratio between the 1st and the 10th dose was 1.31 ± 0.48. Medians of the tiludronate concentration values measured in plasma 8 hours post-dose were not statistically different between doses. Maximum and minimum concentrations of tiludronate (mg/L) following the last dose were 0.91 and 0.04 respectively. It was concluded that the pharmacokinetics of tiludronate in horses are linear from 0.05 to 0.2 mg/kg IV and stationary after 10 IV administrations of 0.1 mg/kg. [less ▲]

Cet article porte sur les pratiques stratégiques de la circulation en ville et s’interroge sur les méthodes d’analyse (sémiotiques, ethnographiques, etc.) des pratiques conflictuelles. Ce travail choisit un double point de vue sur les pratiques : le premier est celui de l’objectivation et de la textualisation des pratiques à travers le point de vue d’un « œil divin » (explication), le deuxième part d’une observation « située » et d’un point de vue incarné (compréhension). Cette recherche s’attache donc à une analyse des dispositifs spatiaux de gestion et de contrôle de la circulation, ainsi qu’aux pratiques d’ajustement en acte. Le trafic urbain est envisagé comme un corps-à-corps technologique où se croisent et se confrontent les compétences des agents humains et des corps machiniques des voitures (compétences stratégique et relationnelle distribuées entre humains et non-humains).

The purpose of the presented research project is to investigate how present-day EO-technology can support local and regional decision-making, particularly in Belgium, and to develop prototype versions of value-added products that fulfill some of the actual information needs, as expressed by Belgian authorities at the local and at the regional level. One of the technical research modules is focussing on the geometrical aspects of VHR data processing. The geometric precision of VHR data (QuickBird, IKONOS) is systematically evaluated, more specific for an urban and suburban environment using the GCP information obtained by GPS measurements. The 2D-georeferenced images is compared with ortho-rectified images in terms of their geometric accuracy. This will provide useful information about the limitations of 2Dcorrected data, and the necessity of acquiring ortho-rectified data, for different kinds of applications in each of the studied areas. The oblique viewing angle of images produced by VHR sensors like IKONOS and QuickBird has a strong influence on the geometrical displacement of objects, and on the occurrence of hidden areas in the image. The degree of displacement and the percentage of hidden areas are determined by the interaction between viewing angle, position of the sun, object height, and terrain characteristics (slope, aspect). In other words, the range of viewing angles that can be considered acceptable for purchasing an image of a certain area will depend on the morphological characteristics of the area. To study the interaction between all parameters involved, a theoretical model is implemented. First, the model is used to systematically study the impact of viewing angle on object displacement, shadow length and size of hidden areas in an image, by simultaneously varying the different morphological parameters. Next, the impact of viewing angle on the geometry of the image is simulated using the theoretical model and a DSM from aerial photography. The geometrical accuracy of a DSM from VHR data is compared with the accuracy of the DSM, derived from aerial photography at scales of 1:12000 and 1:4000). The satellite-derived DSM is used for ortho-rectification of VHR imagery. The accuracy of the ortho-rectified images is compared with ortho-rectifications of the same images, based on the aerial photo DSM. [less ▲]

In this paper we study the concept of electric power system control, when the responsibility for controlling the entire system is shared by agents controlling their assigned areas. Within this framework, we suggest to study the dynamics created by the interactions of agents. In particular, we discuss the relation that exists between the information available to the different agents and their optimisation objective, and the performance of the overall power system. Simulations results, carried out on a 39-node power system voltage control problem, are provided and analyzed. They highlight, among others, the sub-optimal performance level attained by the system when the different agents exchange information about their area dynamics without sharing a common control objective.

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 ▲]

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 ▲]

We find [O/Fe] to gradually increase with decreasing [Fe/H], though considerably slower than has earlier been obtained from OH lines in the UV. A scatter in [O,Mg,Ca,Ti/Fe] at a given [Fe/H] is found and we argue that this scatter is partly real. The deviations from the mean trends of abundance ratios vs [Fe/H] are found to correlate in non-trivial ways for different abundances. Similar trends are found from results of accurate studies by other groups. This seems to give further evidence for the hypothesis that the stars once formed in different subsystems, with different star-formation rates.The paper is in press in A&A, may be obtained as astro-ph/0505118.

Many CAD tools already allow to design and directly manipulate ideas in a digital way. However, designers still use pen and paper during the early design phase of their projects. Indeed, existing CAD tools constraint creative work. There is a need for a spontaneous human computer interaction in design computing. In order to answer to this need, we develop an integrated aided design tool based on a Virtual Desktop. The designer sits in front of a classical desk where s/he can design and manipulate drawings and generated models. This paper describes the observations made during experiment about Virtual Desktop’s use by a designer. The experiment demonstrates that the immersive aspect of our system interface modifies the relationship between the designer and his/her model and, by the way, how this relation generates a new type of augmented interaction.

A 1D coupled physical-biogeochemical model has been built to study the pelagic food web of the Ligurian Sea (NW Mediterranean Sea). The physical model is the turbulent closure model (version 1D) developed at the GHER (University of Liège, Belgium). The ecosystem model contains nineteen state variables describing the carbon and nitrogen cycles of the pelagic food web. Silicate is considered as a potential limiting nutrient of diatoms’ growth. The aggregation model described in Kriest and Evans (2000) is used to evaluate the sinking rate of particulate detritus. The model is forced at the air-sea interface by the METEO France meteorological data. The DYFAMED time series data of year 2000 are used to calibrate and validate the biological model (Raick et al., 2005). By combining the numerical model and the available observations, data assimilation techniques are useful to improve the state estimation of the ocean. A Singular Fixed Extended Kalman filter (Pham et al., 1998) has been implemented in this way. Twin experiments are first performed to choose the suitable experimental protocol, which is then applied to perform real data assimilation experiments using DYFAMED data (Raick et al., submitted). To be coupled in a 3D environment, the ecosystem model is too complex. Our ongoing work is to perform a simplification, by studying simplified structures in comparison with the original ecosystem model. The advantage of deriving a simplified model from the complex one, is that we would be able to identify the most important processes of the Ligurian Sea ecosystem. [less ▲]

Title Inside-out transobturator vaginal tape (TVT-O): One-year results of a prospective study Introduction and Objectives The aim of this study was to prospectively assess the efficacy of a new surgical technique, the inside-out transobturator vaginal tape (TVT-O), for the treatment of female stress urinary incontinence (SUI). Study design, materials and methods From 03/2003 through 10/2003, a TVT-O tape was inserted in 83 consecutive patients with clinical evidence of SUI. Preoperative evaluation included complete history, physical examination, urodynamics, urine analysis, and cystoscopy. None of the patients presented the following exclusion criteria: post-void residual (PVR) >100 cc, detrusor overactivity or acontractility, pregnancy, neurological pathology, active urinary or vaginal infection, age >85 years, negative stress test, and maximum cystometric capacity <300 mL. Post-operative evaluation was carried out using symptom scoring and quality of life (QoL) questionnaires, visual analog scales, physical examination, uroflowmetry, and PVR measurement. Cure was defined as no leakage based on both symptom scale scoring and physical examination. Improvement was defined as ≥50% decrease in symptoms based on the questionnaire’s results. Results Mean age of the patients was 61 years. The TVT-O procedure was associated with pelvic organ prolapse cure in 15 patients (18%). Follow-up time was ≥12 months in all women (mean = 13.6); 3 patients were lost to follow-up. No significant blood loss (≥100 cc), vaginal wall, urethral, or bladder perforation was encountered. No hematoma, vaginal or urethral erosion, or neurological complication was observed. No patient complained of persistent pain. At the latest follow-up visit, max flow rate was ≥10 mL/sec and PVR was <100 cc in 90% and 94% patients, respectively. Two patients underwent an immediate tape release procedure while the tape was sectioned in 2 other patients for retention and/or urgency associated with obstruction. Sixty eight patients (85%) were cured of their SUI while 9 patients (11%) were improved. Urgency questionnaire’s results showed that 5 (5/46) patients developed de novo urgency. Twenty and 14 out of the 34 patients with preoperative urge symptoms reported either disappearance or no change of urgency, respectively. Obstruction symptoms appeared or worsened in 3 patients and were unchanged or decreased in all other patients. Analysis of the incontinence visual analog and QoL scale scores showed that the majority of patients reported disappearance of incontinence together with significant improvement of their QoL. Conclusions The one-year results of this study suggest that TVT-O is associated with a low incidence of peri- and post-operative complications and high objective and subjective SUI cure rates.
