Galvenie akūta retrovirāla sindroma simptomi, ādas un gļotādas izpausmes HIV pozitīviem pacientiem korelācijā ar imūnsupresiju un CD4 T šūnu skaitu L…

2018

Ievads: HIV ir viens no visplašāk izplatījiem vīrusu patogēniem pasaulē. Slimības akūtās fāzes izpausmes ir grūti pamanāmas. Pašreizējie pētījumi liecina, ka svaigi inficēti pacienti gūst priekšrocības no agrīnas diagnostikas attiecībā uz slimības gaitu un dzīves pagarināšanu. Tā kā ādas izpausmes ir vienas no visbiežāk sastopamajām, ir svarīgi tās kritiski izvērtēt gadījumā, ja tās parādās citādi veselīga izskata pacientam. Mērķi: Pētījuma mērķis ir analizēt akūtā retrovīrusu sindroma (ARS) galvenos simptomus, lai veicinātu diagnostiku jau akūtas HIV infekcijas laikā, un noteikt, vai pastāv cieša saikne starp noteiktu ādas bojājumu rašanos un CD4 T šūnu skaitu. Materiāli un metodes: pētīju…

Représentation, analyse et caractérisation de surfaces rugueuses

2020

Nous présentons un projet de recherche dans lequel, nous proposons d’aborder la problématique de la représentation numérique, de l’analyse et de la caractérisation de surfaces rugueuses. La rugosité est un concept complexe, par nature multi-échelle et reposant sur l’étude du comportement local d’une surface dans un voisinage donné. Son évaluation sur les surfaces est essentielle pour de nombreux problèmes expérimentaux. Cela explique les nombreuses études réalisées dans les domaines applicatifs liés à la physique et la mécanique, là où le contrôle et la maîtrise de l’état des surfaces constituent un besoin majeur pour les industriels. Un grand nombre de paramètres conventionnels normalisés …

The focus and timing of gaze matters : Investigating collaborative knowledge construction in a simulation-based environment by combined video and eye…

2022

Although eye tracking has been successfully used in science education research, exploiting its potential in collaborative knowledge construction has remained sporadic. This article presents a novel approach for studying collaborative knowledge construction in a simulation-based environment by combining both the spatial and temporal dimensions of eye-tracking data with video data. For this purpose, we have investigated two undergraduate physics student pairs solving an electrostatics problem in a simulation-based environment via Zoom. The analysis of the video data of the students’ conversations focused on the different collaborative knowledge construction levels (new idea, explication, eval…

Simon Starling, A l’ombre du pin tordu

2018

L’exposition consacrée à l’artiste britannique Simon Starling (1967/) à Sérignan témoigne exemplairement du tournant pris depuis les œuvres des années 1990 et 2000 dont l’une, Shedboatshed, lui a valu le prix Turner en 2005. À vrai dire, l’inflexion de son art vers une interrogation portant non sur l’identité, mais sur la présence était sensible dans une précédente exposition dédoublée entre le Mac/Val et le Parc Saint Léger en 2009. Pratiques de la déconstruction et de la reconstruction, le...

Conditional predictive inference for online surveillance of spatial disease incidence

2011

This paper deals with the development of statistical methodology for timely detection of incident disease clusters in space and time. The increasing availability of data on both the time and the location of events enables the construction of multivariate surveillance techniques, which may enhance the ability to detect localized clusters of disease relative to the surveillance of the overall count of disease cases across the entire study region. We introduce the surveillance conditional predictive ordinate as a general Bayesian model-based surveillance technique that allows us to detect small areas of increased disease incidence when spatial data are available. To address the problem of mult…

Highly-parallelized simulation of a pixelated LArTPC on a GPU

2023

The rapid development of general-purpose computing on graphics processing units (GPGPU) is allowing the implementation of highly-parallelized Monte Carlo simulation chains for particle physics experiments. This technique is particularly suitable for the simulation of a pixelated charge readout for time projection chambers, given the large number of channels that this technology employs. Here we present the first implementation of a full microphysical simulator of a liquid argon time projection chamber (LArTPC) equipped with light readout and pixelated charge readout, developed for the DUNE Near Detector. The software is implemented with an end-to-end set of GPU-optimized algorithms. The alg…

Spatial Cognition 2020/1: Book of abstracts : August 2-4, 2021, University of Latvia

2021

Spatial Cognition is concerned with the acquisition, development, representation, organization, and use of knowledge about spatial objects in real, virtual or hybrid environments and processed by human or artificial agents. Spatial Cognition includes research from different fields insofar as they are concerned with cognitive agents and space, such as cognitive and developmental psychology, linguistics, computer science, geography, cartography, philosophy, neuroscience, and education. Research issues in the field range from the investigation of human spatial cognition to mobile robot navigation, including topics such as wayfinding, spatial planning, spatial learning, internal and external re…
