Compression de code pour processeurs haute performance

Les systemes embarques sont contraints, pour des raisons de cout et d’autonomie, en memoire et en consommation d’energie tout en requerant de plus en plus de performances. La compression de code permet d’optimiser la taille des codes embarques mais aussi leur performance et leur consommation d’energie. La quasi-totalite des travaux sur le sujet proposent des schemas de compression reposant sur une decompression entre la memoire et le cœur du processeur (pre-cache ou post-cache) afin de ne pas modifier ce dernier. Mais ces methodes sont soit tres penalisantes en temps d’execution, soit tres dures a mettre en œuvre pour des processeurs superscalaires. Dans cet article, nous proposons un schema de compression reposant sur une decompression au sein du pipeline adapte aux processeurs embarques haute performance ; nous montrons qu’il permet d’optimiser les trois criteres simultanement et ce pour differentes caracteristiques architecturales.
Cultural nationalism, neither ethnic nor civic

Soulevant la question d'un nationalisme liberal propre a defendre la souverainete du Quebec et son independance par rapport au Canada, l'A. montre qu'il existe une conception culturelle du nationalisme qui, au-dela des formes civique et ethnique du nationalisme, evite le double ecueil de l'anti-democratisme et du fanatisme et s'avere compatible avec le liberalisme politique
Mesenchymal stem cells impair in vivo T-cell priming by dendritic cells

Dendritic cells (DC) are highly specialized antigen-presenting cells characterized by the ability to prime T-cell responses. Mesenchymal stem cells (MSC) are adult stromal progenitor cells displaying immunomodulatory activities including inhibition of DC maturation in vitro. However, the specific impact of MSC on DC functions, upon in vivo administration, has never been elucidated. Here we show that murine MSC impair Toll-like receptor-4 induced activation of DC resulting in the inhibition of cytokines secretion, down-regulation of molecules involved in the migration to the lymph nodes, antigen presentation to CD4+ T cells, and cross-presentation to CD8+ T cells. These effects are associated with the inhibition of phosphorylation of intracellular mitogen-activated protein kinases. Intravenous administration of MSC decreased the number of CCR7 and CD49dβ1 expressing CFSE-labeled DC in the draining lymph nodes and hindered local antigen priming of DO11.10 ovalbumin-specific CD4+ T cells. Upon labeling of DC with technetium-99m hexamethylpropylene amine oxime to follow their in vivo biodistribution, we demonstrated that intravenous injection of MSC blocks, almost instantaneously, the migration of subcutaneously administered ovalbumin-pulsed DC to the draining lymph nodes. These findings indicate that MSC significantly affect DC ability to prime T cells in vivo because of their inability to home to the draining lymph nodes and further confirm MSC potentiality as therapy for immune-mediated diseases.
Cellular system physical layer throughput: How far off are we from the shannon bound?

Cellular wireless systems have made impressive progress over the past two decades. They currently connect more than five billion people worldwide. With the advent of turbo decoders in the 1990s, the design of optimal decoders very close to the Shannon bound became possible in AWGN channels. Nowadays many researchers believe that this is true for entire wireless systems and that therefore there is not much left to investigate. In this contribution, we take a closer look at WiMAX and HSDPA, two successful cellular systems being operated currently in many countries, and check their truly achievable performance. We have measured the physical layer throughput of WiMAX and HSDPA in various realistic environments (urban and mountainous) with high-quality equipment and different antenna configurations. We furthermore compared the throughput measured to the Shannon bound. Based on our measurements, we analyze the losses in design and implementation (e.g., pilots, guard carriers, coding, equalization, and channel estimation) and report our findings. Surprisingly, we are currently only utilizing 40 percent of the available channel capacity; or roughly equivalently, we are up to 10 dB off the Shannon bound at typical operational points, thus providing a lot of potential improvement for future 4G systems. In advanced four transmit antenna configurations of HSDPA, the losses are even more pronounced, showing that our current standards are not well suited to take advantage of the much higher capacity provided.
La formación profesional, entramado de contenidos, escenarios y actores Professional preparation, a framework of contents, stages and actors

The present study was geared to analyze professional preparation processes from the perspective of actors (tutors and tutees) in a masters program in Educational Psychology. The experience suggests that professional preparation requires guided as well as independent activities in which students employ their knowledge, carry out actions, and reflect about them in order to build a complex, functional and flexible professional consciousness. Processes analyzed were: 1) learning and change, 2) practice, 3) mediation and 4) reflection; all in educational settings. Participants (tutors and tutees) engaged in processes of analyses, reflection and learning which evolved gradually into a personal epistemology of practice. Results indicated that students acquired deep and well structured understandings of their own strengths and needs. Tutors continue to evolve in their conceptions and actions to guide the formative processes of highly qualified professionals in educational settings.
Performance profile of sodium hyaluronate in patients with lipid tear deficiency: randomised, double-blind, controlled, exploratory study

Aim: To assess the short-term efficacy of hypotonic 0.18% sodium hyaluronate in patients with evaporative tear-sufficient dry eye due to lipid tear deficiency (LTD). Methods: This was a randomised, double-blind, controlled, exploratory study. A total of 10 patients with dry eye due to LTD were treated as follows: one drop of hypotonic 0.18% sodium hyaluronate in one eye and one drop of isotonic 0.3% hydroxypropyl-methylcellulose (HPMC)/0.1% dextran in the other eye. Non-invasive tear film break-up time (NIBUT) evaluated by using a tear scope with grid pattern and subjective ocular symptoms of dry eye were assessed at 15, 30, 60 and 90 min after instillation. Results: Both sodium hyaluronate and HPMC/dextran caused a significant (p<0.05) improvement in NIBUT and symptoms. Mean (SD) NIBUT in the sodium hyaluronate group was 3.2 (1.0), 6.4 (2.8), 5.5 (1.9), 5.3 (1.3) and 3.9 (1.7) s at 0, 15, 30, 60 and 90 min, respectively, compared with 3.6 (1.9), 5.5 (3.2), 5.0 (1.5), 4.4 (2.2) and 3.5 (1.2) s in the HPMC/dextran group. However, increase in NIBUT was significantly (p<0.05) greater and longer in the sodium hyaluronate group than in the HPMC/dextran group. Conclusion: Treatment with sodium hyaluronate and HPMC/dextran eye drops is useful for treating patients with dry eye due to LTD. However, sodium hyaluronate caused a significantly (p<0.05) greater increase in NIBUT values than HPMC/dextran in such patients.
The transputer

The transputer is a programmable VLSI component with communication links for point-to-point connection to other transputers. Occam (*) is a language that enables a multi-transputer system to be described as a collection of processes that ogerate concurrently and communicate using message passing via named channels. The INMOS transputer architecture is standardized at the level off the definition of occam (rather than at the level of the definition of an instruction set). The implementation of the first commercially available transputers is illustrated by describing the implementation of occam. The paper concludes with outline examples of some applications. 1 Introduction The transp~ater architecture has been developed to fulfil four main objectives: To create a commercial product range that sets new standards in ease of programming and ease of engineering. To provide the maximum performance to the user. To exploit future developments in VLSI technology within a compatible family. To create a programmable component that can be used to build systems with large numbers of concurrent computing elements. VLSI currently permits 5-10 MIP processors to be manufactured in volume for low prices. There is therefore no economic barrier to the construction of very powerful computer systems containing many processing elements, The challenge is a technical one: how to engineer a system with, say, 1000 processors so as to make the inherent concurrency usable, and how to support the design of applications to take advantage of this amount of concurrency. (*) oceam is a trade mark of the INMOS Group of Companies In the transputer architecture, the exploitation of a high degree of concurrency is made possible through a decentralized model of computation, in which local computation takes place on local data, and concurrent processes communicate by passing messages on point to point channels. The localized communications architecture also has substantial engineering advantages, described below. An important design objective of oecam and the transputer was to provide the same concurrent programming techniques both for a single transputer and for a network of transputers. Consequently, the features of occam were chosen to ensure an efficient distributed implementation on transputer systems. The concurrent processing mechanisms within the transputer were then designed to match. The result is that a program ultimately intended for a network of transputers can be compiled and executed efficiently by a single computer used for program development. Once the logical behaviour of the program has been verified, the program may be configured for …

Rendering Railway Scenes in Cyberspace Based on Route Panoramas

The high demand from railway safety has promoted the sensing technology to avoid manual inspection that is error-prone, low efficiency, labor-intensive and high costs. However, few works have emphasized railway environmental monitoring so far which is equally important in railway safety maintenance. In this paper, we propose a railway scene rendering system for virtual maneuver and inspection. Based on the route panoramas extracted from a real train-borne video, we generate the compact and high fidelity scenes over a long distance route in cyberspace. We analyze the relation between train motion and the video sampling in order to obtain the route panoramas of the railways at the just-sampling rate. Then, we render scene tunnels based on the route panorama in a virtual space for interactive navigation, inspection, and scene indexing. The experimental results show remarkable advantages in the data storage and automatic inspection. The compact data format with sufficient visual information can be transmitted and released in cyberspace for fast access, maneuver, and automatic retrieval in railway environment monitoring.
THE MULTIPLICATION OF AVIAN ENCEPHALOMYELITIS VIRUS IN CHICKEN EMBRYO TISSUES.

Attempts have been made to propagate the virus of avian encephalomyelitis (AE) in a variety of systems including cell cultures (1), laboratory animals (5), and embryonating chicken eggs (7,9). The success reported by Hwang et al. (1) in growing this virus in cell cultures was in error; the tissueculture agent was later identified as a CELO virus and was found to be a contaminant of the AE stock virus (4). Embryonating chicken eggs from susceptible dams (8) have become the system of choice in working with AE virus in the laboratory. Various routes of inoculation have been used to grow this virus in eggs (2,3,7), but no report has been found which indicates the concentration of virus in the various tissues and fluids of the embryonating chicken egg.

Multiple Program Participation and Exits from Food Stamps among Elders

This article uses population-level administrative data from Rhode Island's Food Stamp Program to examine exits from the Food Stamp Program by elders. Multivariate event history models estimate the relations of multiple program participation and the timing of eligibility reviews to the probability of exiting food stamps. Results suggest that elders who are age 65 or older and who receive both Supplemental Security Income and food stamps have a higher probability of exiting the Food Stamp Program than do elders who receive only food stamps. The timing of eligibility reviews is also found to be positively associated with the probability of exit from food stamps. This article is argued to extend conceptual models of the determinants of food stamp exits.
Physicochemical and Spectroscopic Characterization of p-Chlorobenzaldehyde: An Impact of Biofield Energy Treatment

p-Chlorobenzaldehyde (p-CBA) is used as an important chemical intermediate for the preparation of pharmaceuticals, agricultural chemicals, dyestuffs, optical brighteners, and metal finishing products. The study aimed to evaluate the effect of biofield energy treatment on the physicochemical and spectroscopic properties of p-CBA. The study was accomplished in two groups i.e. control and treated. The control group was remained as untreated, while the treated group was subjected to Mr. Trivedi’s biofield energy treatment. Finally, both the samples (control and treated) were evaluated using various analytical techniques. The surface area analysis showed a substantial increase in the surface area by 23.06% after biofield treatment with respect to the control sample. The XRD analysis showed the crystalline nature of both control and treated samples. The X-ray diffractogram showed the significant alteration in the peak intensity in treated sample as compared to the control. The XRD analysis showed the slight increase (2.31%) in the crystallite size of treated sample as compared to the control. The TGA analysis exhibited the decrease (10%) in onset temperature of thermal degradation form 140°C (control) to 126°C in treated sample. The T max (maximum thermal degradation temperature) was slightly decreased (2.14%) from 157.09°C (control) to 153.73°C in treated sample of p-CBA. This decrease in T max was possibly due to early phase of vaporization in treated sample as compared to the control. The FT-IR spectrum of treated p-CBA showed the increase in wavenumber of C=C stretching as compared to the control. The UV spectroscopic study showed the similar pattern of wavelength in control and treated samples. Altogether, the surface area, XRD, TGA-DTG and FT-IR analysis suggest that Mr. Trivedi’s biofield energy treatment has the impact to alter the physicochemical properties of p-CBA. This treated p-CBA could be utilized as a better chemical intermediate than the control p-CBA for the synthesis of pharmaceutical drugs and organic chemicals.

Personalized intelligent question answering algorithm in e-learning

A personalized intelligent question answering algorithm is put up, which takes learners' personality into account based on learners' information. By introducing principal component analysis, the algorithm got comprehensive variables, and constructed the learner model. Subsequently, the paper analyzed how to integrate the learner's characteristic and his question using harmony theory to dynamically produce a question model. Using the question model, this algorithm obtained the parameters of answer depth and presentation pattern adapted to the learner's personality. Finally, according to parameters, personalized answer was matched for the learner by the application of adaptive neuron-fuzzy inference system (ANFIS). For that reason, the personalized intelligent question answering algorithm is able to make learners understand the answer better, and guarantee the efficiency of intelligent question answering.
Fine-tune your smile: Correction to Hagan et al

In this small note we use results derived in Berestycki et al. to correct the celebrated formulae of Hagan et al. We derive explicitly the correct zero order term in the expansion of the implied volatility in time to maturity. The new term is consistent as $\beta\to 1$. Furthermore, numerical simulations show that it reduces or eliminates known pathologies of the earlier formula.
Patterns and risks in spinal trauma

Background: Spinal injury in children is rare, and poses many difficulties in management. Aims: To ascertain the prevalence of spinal injury within the paediatric trauma population, and to assess relative risks of spinal injury according to age, conscious level, injury severity score (ISS), and associated injuries. Methods: Spine injured children were identified from the UK Trauma Audit & Research Network Database from 1989 to 2000. Relative risks of injury were calculated against the denominator paediatric trauma population. Results: Of 19 538 on the database, 527 (2.7%) suffered spinal column fracture/dislocation without cord injury and 109 had cord injury (0.56% of all children; 16.5% of spine injured children). Thirty children (0.15% of all children; 4.5% of spine injured children) sustained spinal cord injury without radiological abnormality (SCIWORA). Cord injury and SCIWORA occurred more commonly in children aged ⩽8. The risk of spine fracture/dislocation without cord injury was increased with an ISS >25 and with chest injuries. The risk of cord injury was increased with reduced GCS, head injury, and chest injury. Conclusions: Spinal cord injury and SCIWORA occur more frequently in young children. Multiple injuries and chest injuries increase the risk of fracture/dislocation and of cord injury. Reduced GCS and head injuries increase the risk of cord injury.
Educating African American Men about the Prostate Cancer Screening Dilemma: A Randomized Intervention

Background: Until there is a definitive demonstration that early diagnosis and treatment of prostate cancer reduces disease-related mortality, it is imperative to promote informed screening decisions by providing balanced information about the potential benefits and risks of prostate cancer screening. Within a community/academic collaboration, we conducted a randomized trial of a printed booklet and a videotape that were designed for African American (AA) men. The purpose of the trial was to determine the effect of the interventions on knowledge, decisional conflict, satisfaction with the screening decision, and self-reported screening. Methods: Participants were 238 AA men, ages 40 to 70 years, who were members of the Prince Hall Masons in Washington, DC. Men were randomly assigned to the (a) video-based information study arm, (b) print-based information study arm, or (c) wait list control study arm. Intervention materials were mailed to men at home. Assessments were conducted at baseline, 1 month, and 12 months postintervention. Multivariate analyses, including ANCOVA and logistic regression, were used to analyze group differences. Results: The booklet and video resulted in a significant improvement in knowledge and a reduction in decisional conflict about prostate cancer screening, relative to the wait list control. Satisfaction with the screening decision was not affected by the interventions. Self-reported screening rates increased between the baseline and the 1-year assessment, although screening was not differentially associated with either of the interventions. In exploratory analyses, prostate-specific antigen testing at 1 year was more likely among previously screened men and was associated with having low baseline decisional conflict. Conclusions: This study represents one of the first randomized intervention trials specifically designed to address AA men's informed decision making about prostate cancer screening. We have developed and evaluated culturally sensitive, balanced, and disseminable materials that improved knowledge and reduced decisional conflict about prostate cancer screening among AA men. Due to the high incidence and mortality rates among AA men, there is a need for targeted educational materials, particularly materials that are balanced in terms of the benefits and risks of screening.

Poor health-related quality of life in the Swedish general population: The association with disease and lifestyle factors

Aim: Poor health-related quality of life (HRQoL) is associated with increased use of healthcare services, but it remains unclear which individuals have a heightened risk in the general population. Methods: A Swedish population-based cross-sectional survey was conducted in 2008. Predefined risk characteristics including sex, age, educational level, marital status, body mass index, diseases, physical activity, and tobacco smoking were collected by a self-report questionnaire. Five aspects of the EORTC QLQ-C30 were used to assess HRQoL: physical, role, emotional, social, and cognitive function. Participants were defined as having “poor HRQoL” if they scored ≥10 points (scale 0–100) lower than the mean score of the total sample. To assess the characteristics of individuals with poor HRQoL, classification and regression tree (CART) analysis was performed. Results: A total of 4910 (70.5% participation rate) randomly selected individuals participated in the study. The CART analysis showed that for each of the five functional aspects of HRQoL, the most important covariate HRQoL was the number of reported diseases, while the second strongest covariate was physical inactivity. Conclusion: This large population-based study indicates that a higher number of diseases and physical inactivity are the most important covariates of poor HRQoL in the Swedish general population.
