Simulation du comportement humain en situation d’évacuation de bâtiment en feu

L’objectif de cette these est de proposer un modele comportemental de l’etre humain pour la simulation d’evacuation de bâtiment en cas d’incendie et de l’integrer dans un outil de simulation d’evacuation de bâtiment. Le modele propose represente une approche individu-centre du comportement et repond aux axiomes de la Rationalite Limitee enonces par Herbert Simon grâce a une conception hierarchique des moyens cognitifs des agents simules. L’implementation du modele du comportement presente la particularite d’etre integralement realisee en GPU (via OpenGL 2.0). Ainsi la frequence du moteur de comportement est tres proche de celle du simulateur et permet une adaptation quasi temps reel des comportements des agents a un changement de perception de leur environnement. Le logiciel d’evacuation developpe permet :– l’importation de scenario d’incendie de bâtiment simule grâce au logiciel FDS,– la configuration des archetypes de comportement des agents evacuant, notamment :– la description des hypotheses sur le monde (connaissance individuelle),– la configuration des comportements des agents (moyens cognitifs individuels). – le positionnement des agents dans le bâtiment,– la simulation de l’evacuation,– l’enregistrement et le play-back d’un scenario d’evacuation.Les contraintes (feu, fumee, obstacles, autres agents) captees par un agent sont interpretees par ce dernier en fonction de son archetype de comportement afin de determiner si sa strategie d’evacuation doit etre remise en cause.
PlantRT : a Distributed and Diversified Recommendation Tool for Citizen Sciences

De nombreux domaines scientifiques produisent et consomment des volumes de donnees considerables (e.g.biologie, astronomie, physique). Dans ce travail, nous nous interessons au traitement de donnees de type images, produites a grande echelle par des botanistes via Pl@ntNet. L'objectif de notre prototype, PlantRT, est de permettre l'etude de l'evolution et des correlations de familles de plantes diverses. Chaque image, ou observation, est ainsi produite de facon personnelle - par chaque citoyen ou botaniste participant au projet -, et peut etre stockee sur differents types de sites (e.g. ordinateurs personnels, smartphones, serveurs, clouds). Par ailleurs, l'emergence des systemes de recommandation distribues favorise le partage, la decouverte et la mise en relation de ces donnees produites par chaque citoyen implique. Cet article presente PlantRT, un prototype de systeme de recommandation multi-sites, prenant en compte la diversite des profils des utilisateurs, et des donnees, favorisant, par exemple, la decouverte de nouvelles especes de plantes d'une meme famille ou de la meme zone geographique, ainsi que le passage a l'echelle. Nous montrons ici, en particulier, plusieurs cas d'utilisations, de meme que le deploiement de PlantRT en detail.
Associations between the atrial electromechanical interval, atrial remodelling and outcome of catheter ablation in paroxysmal atrial fibrillation

Objective The atrial electromechanical (PA–PDI) interval was reported to be a useful predictor of new-onset atrial fibrillation (AF) and the occurrence of AF after coronary artery bypass surgery. The aim of this study was to investigate the associations of the electromechanical interval with atrial substrate properties and the outcome of catheter ablation in paroxysmal AF patients. Methods 132 paroxysmal AF patients who had received catheter ablation were enrolled. The electromechanical interval was determined as the time interval from the initiation of P-wave deflection to the peak of the mitral inflow A-wave on pulse-wave Doppler imaging. The left atrial voltage and total activation time were collected before pulmonary vein isolation. Every patient underwent standard follow-up after catheter ablation. Results The PA–PDI interval was significantly correlated with the left atrial dimension (r=0.419, p=0.003), left atrial volume (r=0.827, p<0.001), left atrial voltage (r=−0.451, p<0.001) and left atrial activation time (r=0.547, p<0.001). During a follow-up of 23±13 months, 36 patients (27% of the study population) had AF recurrence. The PA–PDI interval and left atrial volume were independent predictors of AF recurrence. At a cut-point of 160 ms, the Kaplan–Meier survival analysis showed that a long PA–PDI interval significantly predicted AF recurrence. Conclusions The PA–PDI interval can reflect the process of left atrial remodelling, such as a left atrial enlargement, prolonged activation time and decreased voltage. It was a convenient parameter for predicting recurrence after catheter ablation of paroxysmal AF.

A comparison of four treatments for generalized convulsive status epilepticus. Veterans Affairs Status Epilepticus Cooperative Study Group.

BACKGROUND AND METHODS Although generalized convulsive status epilepticus is a life-threatening emergency, the best initial drug treatment is uncertain. We conducted a five-year randomized, double-blind, multicenter trial of four intravenous regimens: diazepam (0.15 mg per kilogram of body weight) followed by phenytoin (18 mg per kilogram), lorazepam (0.1 mg per kilogram), phenobarbital (15 mg per kilogram), and phenytoin (18 mg per kilogram). Patients were classified as having either overt generalized status epilepticus (defined as easily visible generalized convulsions) or subtle status epilepticus (indicated by coma and ictal discharges on the electroencephalogram, with or without subtle convulsive movements such as rhythmic muscle twitches or tonic eye deviation). Treatment was considered successful when all motor and electroencephalographic seizure activity ceased within 20 minutes after the beginning of the drug infusion and there was no return of seizure activity during the next 40 minutes. Analyses were performed with data on only the 518 patients with verified generalized convulsive status epilepticus as well as with data on all 570 patients who were enrolled. RESULTS Three hundred eighty-four patients had a verified diagnosis of overt generalized convulsive status epilepticus. In this group, lorazepam was successful in 64.9 percent of those assigned to receive it, phenobarbital in 58.2 percent, diazepam plus phenytoin in 55.8 percent, and phenytoin in 43.6 percent (P=0.02 for the overall comparison among the four groups). Lorazepam was significantly superior to phenytoin in a pairwise comparison (P=0.002). Among the 134 patients with a verified diagnosis of subtle generalized convulsive status epilepticus, no significant differences among the treatments were detected (range of success rates, 7.7 to 24.2 percent). In an intention-to-treat analysis, the differences among treatment groups were not significant, either among the patients with overt status epilepticus (P=0.12) or among those with subtle status epilepticus (P=0.91). There were no differences among the treatments with respect to recurrence during the 12-hour study period, the incidence of adverse reactions, or the outcome at 30 days. CONCLUSIONS As initial intravenous treatment for overt generalized convulsive status epilepticus, lorazepam is more effective than phenytoin. Although lorazepam is no more efficacious than phenobarbital or diazepam plus phenytoin, it is easier to use.
High Voltage Stress Induced in Transparent Polycrystalline Diamond Field-Effect Transistor and Enhanced Endurance Using Thick Al2O3 Passivation Layer

A transparent polycrystalline diamond field-effect transistor (FET) was fabricated and measured in room temperature measurements, which reveals comparatively high maximum current density and high breakdown voltage of more than 1000 V. A harsh stress environment is proposed for simple and time-effective reliability stress measurement of the FET using a method of 50 continuous cycles of 500-V voltage stress. A 400-nm-thick Al<sub>2</sub>O<sub>3</sub> counter-destructive passivation layer was implemented on the FET for the stress measurements. Devices with wide gate–drain length (<inline-formula> <tex-math notation="LaTeX">${L}_\text {GD}$ </tex-math></inline-formula>) retain their FET characteristics after the harsh stress measurements by only 50% reductions maximum current density.
Reliability Evaluation of Distribution Network Power Supply Based on Improved Sampling Monte Carlo Method

As the scale of power system continues to expand and the conditions for system operation become complicated, more random factors need to be considered in power system reliability evaluation, which leads to considerable increase in calculation workload. The commonly used reliability assessment method - analytical method cannot meet the demand. The appropriate Monte Carlo method needs to be selected and improved to meet the needs of speed and accuracy. The Monte Carlo method has unique advantages in calculating large complex distribution networks. This paper improves the sampling method of Monte Carlo method. The improved important sampling algorithm realizes the optimization of state probability distribution for power system. Test results show that the method has good engineering application value.

Zik1, a Transcriptional Repressor That Interacts with the Heterogeneous Nuclear Ribonucleoprotein Particle K Protein*

The heterogeneous nuclear ribonucleoprotein particle (hnRNP) K protein is comprised of multiple modular domains that serve to engage a diverse group of molecular partners including DNA, RNA, the product of the proto-oncogene vav, and tyrosine and serine/threonine kinases. To identify additional K protein molecular partners and to further understand its function, we used a fragment of K protein as a bait in the yeast two-hybrid screen. The deduced primary structure of one of the positive clones revealed a novel zinc finger protein, hereby denoted as Zik1. In addition to the nine contiguous zinc fingers in the C terminus, Zik1 contains a KRAB-A domain thought to be involved in transcriptional repression. Zik1 and K protein bound in vitro and co-immunoprecipitated from cell extracts indicating that in vivo their interaction is direct. Expression of Gal4 DNA-binding domain-Zik1 fusion protein repressed a gene promoter bearing Gal4-binding elements, indicating that from cognate DNA elements Zik1 is a transcriptional repressor. The known diverse nature of K protein molecular interactions and now the identification of a K protein partner that is a transcriptional repressor lends support to the notion that K protein is a remarkably versatile molecule that may be acting as a docking platform to facilitate communication among molecules involved in signal transduction and gene expression.

Native Cell Wall Organization Shown by Cryo-Electron Microscopy Confirms the Existence of a Periplasmic Space in Staphylococcus aureus

ABSTRACT The current perception of the ultrastructure of gram-positive cell envelopes relies mainly on electron microscopy of thin sections and on sample preparation. Freezing of cells into a matrix of amorphous ice (i.e., vitrification) results in optimal specimen preservation and allows the observation of cell envelope boundary layers in their (frozen) hydrated state. In this report, cryo-transmission electron microscopy of frozen-hydrated sections of Staphylococcus aureus D2C was used to examine cell envelope organization. A bipartite wall was positioned above the plasma membrane and consisted of a 16-nm low-density inner wall zone (IWZ), followed by a 19-nm high-density outer wall zone (OWZ). Observation of plasmolyzed cells, which were used to artificially separate the membrane from the wall, showed membrane vesicles within the space associated with the IWZ in native cells and a large gap between the membrane and OWZ, suggesting that the IWZ was devoid of a cross-linked polymeric cell wall network. Isolated wall fragments possessed only one zone of high density, with a constant level of density throughout their thickness, as was previously seen with the OWZs of intact cells. These results strongly indicate that the IWZ represents a periplasmic space, composed mostly of soluble low-density constituents confined between the plasma membrane and OWZ, and that the OWZ represents the peptidoglycan-teichoic acid cell wall network with its associated proteins. Cell wall differentiation was also seen at the septum of dividing cells. Here, two high-density zones were sandwiched between three low-density zones. It appeared that the septum consisted of an extension of the IWZ and OWZ from the outside peripheral wall, plus a low-density middle zone that separated adjacent septal cross walls, which could contribute to cell separation during division.
Assumed oxygen consumption based on calculation from dye dilution cardiac output: an improved formula.

This study was performed because of observed differences between dye dilution cardiac output and the Fick cardiac output, calculated from estimated oxygen consumption according to LaFarge and Miettinen, and to find a better formula for assumed oxygen consumption. In 250 patients who underwent left and right heart catheterization, the oxygen consumption VO2 (ml.min-1) was calculated using Fick's principle. Either pulmonary or systemic flow, as measured by dye dilution, was used in combination with the concordant arteriovenous oxygen concentration difference. In 130 patients, who matched the age of the LaFarge and Miettinen population, the obtained values of oxygen consumption VO2(dd) were compared with the estimated oxygen consumption values VO2(lfm), found using the LaFarge and Miettinen formulae. The VO2(lfm) was significantly lower than VO2(dd); -21.8 +/- 29.3 ml.min-1 (mean +/- SD), P < 0.001, 95% confidence interval (95% CI) -26.9 to -16.7, limits of agreement (LA) -80.4 to 36.9. A new regression formula for the assumed oxygen consumption VO2(ass) was derived in 250 patients by stepwise multiple regression analysis. The VO2(dd) was used as a dependent variable, and body surface area BSA (m2). Sex (0 for female, 1 for male), Age (years), Heart rate (min-1) and the presence of a left to right shunt as independent variables. The best fitting formula is expressed as: VO2(ass) = (157.3 x BSA + 10.0 x Sex - 10.5 x In Age + 4.8) ml.min-1, where ln Age = the natural logarithm of the age. This formula was validated prospectively in 60 patients. A non-significant difference between VO2(ass) and VO2(dd) was found; mean 2.0 +/- 23.4 ml.min-1, P = 0.771, 95% Cl = -4.0 to +8.0, LA -44.7 to +48.7. In conclusion, assumed oxygen consumption values, using our new formula, are in better agreement with the actual values than those found according to LaFarge and Miettinen's formulae.
ST-segment elevation resolution in lead aVR: a strong predictor of adverse outcomes in patients with non-ST-segment elevation acute coronary syndrome.

BACKGROUND The impact of ST-segment elevation resolution in lead aVR on outcomes in patients with non-ST-segment elevation acute coronary syndromes (NSTE-ACS) is unclear. METHODS AND RESULTS Electrocardigrams (ECGs) were recorded on admission and 6 h later in 367 patients with NSTE-ACS. ST-segment deviation >or=0.5 mm was considered significant: 92 patients had ST-segment elevation in lead aVR on admission ECG (ST upward arrowaVR), and 275 did not. Among patients with ST upward arrowaVR, 50 had ST resolution, defined as a reduction >50% in the degree of ST-segment elevation in lead aVR from admission to 6 h later, and 42 did not. ST upward arrowaVR without ST resolution was associated with older age, greater ST-segment depression in other leads on admission and 6 h later, higher rates of positive troponin T, left main and/or 3-vessel coronary disease, and adverse events such as death, (re)infarction, or urgent revascularization within 30 days after admission. Multivariate analysis showed that ST upward arrowaVR without ST resolution was the strongest independent predictor of death or (re)infarction within 30 days after admission (hazard ratio 5.62, p=0.018). CONCLUSIONS ST upward arrowaVR without ST resolution is a strong predictor of 30-day adverse outcomes and correlates with the extent and severity of coronary artery disease in patients with NSTE-ACS.
Explicit adaptive synchronization of multi-agent uncertain systems with heterogeneous dynamic networks

This paper proposes an explicit adaptive algorithm to solve the problem of heterogeneous dynamic synchronization of multi-agent uncertain systems. Different from the existing works, the proposed algorithm depends on less control parameters and achieves zero synchronization error between the agents of heterogeneous uncertain dynamic networks and virtual target. By introducing appropriate assumptions, a class of explicit adaptive synchronization protocols is designed based on a combination of the virtual target's states, distributed feedback gain, and the limited neighboring agents' information. By using Lyapunov function approach, it is proved that the explicit adaptive synchronization problem of closed-loop multi-agent uncertain systems with heterogeneous dynamic networks can be solved, if the control parameters of the explicit adaptive synchronization algorithm are suitably selected. Finally, an example is given to demonstrate the proposed theory.
Gamifying E-learning Course Content

Nowadays, the ability to design teaching and learning tools and content in the form of innovative ICT based educational applications is an essential skill given the increasing time that people spend on mobile devices and the transformation of educational systems to accommodate both formal and non-formal education and align them with life – long learning and the increasing demand for distance education. Persuasive technologies and methodologies, such as gamification, have been adjusted and developed to conform with Learning Management Systems used for online education in order to foster the students' motivation and boost their performance. In this paper, we introduce a methodology for developing educational applications based on well-established behavioral and cognitive models making use of gamification elements. Guidelines for developing a gamified course are offered and instances of a sample gamified course offered on the Moodle platform are presented to illustrate the use of the available mechanics.

Intelligent adaptive observer-based optimal control of overhead transmission line de-icing robot manipulator

Graphical Abstract In cold season, wet snow ice accretion on overhead transmission lines increases wind load effects which in turn increases line tension. This increased line tension causes undesirable effects in power systems. This paper discusses the design of an observer-based boundary sliding mode control (BSMC) for 3 DOF overhead transmission line de-icing robot manipulator (OTDIRM). A robust radial basis functional neural network (RBFNN) observer-based neural network (NN) controller is developed for the motion control of OTDIRM, which is a combination of BSMC, NN approximation and adaptation law. The RBFNN-based adaptive observer is designed to estimate the positions and velocities. The weights of both NN observer and NN approximator are tuned off-line using particle swarm optimization. Using Lyapunov analysis the closed loop tracking error was verified for a 3 DOF OTDIRM. Finally, the robustness of the proposed neural network-based adaptive observer boundary sliding mode control (NNAOBSMC) was verified against the input disturbances and uncertainties.
