Optical techniques for river flow monitoring: an automatic procedure for the identification of the best video sequence to process by LS-PIV technique
2022
Technological advances over last decades gave an innovative impulse to the development of new streamflow measurements techniques, especially regarding remote flow monitoring methods that allow for non-intrusive measurements. The most widely used image-based techniques are the optical ones, such as Large-Scale Particle Image Velocimetry (LS-PIV) and Large-Scale Particle Tracking Velocimetry (LS-PTV). The dynamic movement of tracers floating on the water surface of a river is recorded, and the resulting videos are processed by applying a statistical cross-correlation analysis to detect the most probable frame-by-frame displacement, finally deriving the surface velocity field. To obtain river …
Update of the search for supersymmetric particles in scenarios with Gravitino LSP and Sleptons NLSP
2001
An update of the search for sleptons, neutralinos and charginos in the context of scenarios where the lightest supersymmetric particle is the gravitino and the next-to-lightest supersymmetric particle is a slepton, is presented, together with the update of the search for heavy stable charged particles in light gravitino scenarios and Minimal Supersymmetric Standard Models. Data collected in 1999 with the DELPHI detector at centre-of-mass energies around 192, 196, 200 and 202 GeV were analysed. No evidence for the production of these supersymmetric particles was found. Hence, new mass limits were derived at 95% confidence level.
Dinamiskās spēles ar nepilnu informāciju
2019
Bakalaura darba tēma “Dinamiskās spēles ar nepilnu informāciju” izvēlēta, lai dotu priekšstatu par dinamisko (ekstensīvo jeb pozīciju) spēļu būtību (jēdzienu). Bakalaura darba mērķis ir dinamisko spēļu ar nepilnu informāciju izpēte. Darbā tiek aplūkotas tādas dinamiskās spēles, kurās spēlētājam nav informācijas par to, kādu gājienu ir izdarījis viņa pretinieks, tad viņš nevar izšķirt, kurā no spēles mezgliem viņš atrodas. Kā spēles ar nepilnu informāciju tiek apskatītas Beijesa spēle un signālspēle. Lai labāk izprastu doto spēļu jēdzienus, spēļu norises gaita tiek ilustēta ar piemēriem. Darba autors ir veicis signālspēlēs jutīguma analīzi, lai noskaidrotu, cik lielā mērā drīkst izmainīt ieg…
A genomewide association study of smoking relapse in four European population-based samples.
2013
OBJECTIVES: Genomewide association studies (GWAS) have identified clear evidence of genetic markers for nicotine dependence. Other smoking phenotypes have been tested, but the results are less consistent. The tendency to relapse versus the ability to maintain long-term abstinence has received little attention in genetic studies; thus, our aim was to provide a better biological understanding of this phenotype through the identification of genetic loci associated with smoking relapse. METHODS: We carried out a GWAS on data from two European population-based collections, including a total of 835 cases (relapsers) and 990 controls (abstainers). Top-ranked findings from the discovery phase were …
Optical techniques: non-intrusive river monitoring approach
2022
<p>Technological advances over last decades gave an innovative impulse to development of new streamflow measurements techniques, making possible to implement remote flow monitoring methods that allow for non-intrusive measurements. Here, we focus on image-based techniques that involve the use of digital camera, either installed on a bridge or equipped by a drone (UAVs – Unmanned Aerial Vehicles). The most widely known and used optical techniques are the Large-Scale Particle Image Velocimetry and the Large-Scale Particle Tracking Velocimetry. Optical techniques are based on four main steps: (i) seeding and recording, (ii) images pre-processing, (iii) images proces…
Evaluating Assessment. Validation with PLS-SEM of ATAE Scale for the Analysis of Assessment Tasks
2020
One of the essential functions of university teachers lies in the decision-making process regarding the various components included in assessment process design, where the quality of assessment tasks is a key aspect. This study presents both validation of an instrument for students to evaluate the assessment tasks and the model that upholds the relationships between constructs that characterise the assessment tasks. Working from a review of the literature, a theoretical model has been devised featuring the characteristics of the assessment tasks and the relationships between them. The Analysis of the Assessment and Learning Tasks questionnaire (ATAE) has been designed to check them, based o…
DNA methylation changes associated with prenatal mercury exposure:A meta-analysis of prospective cohort studies from PACE consortium
2022
Mercury (Hg) is a ubiquitous heavy metal that originates from both natural and anthropogenic sources and is transformed in the environment to its most toxicant form, methylmercury (MeHg). Recent studies suggest that MeHg exposure can alter epigenetic modifications during embryogenesis. In this study, we examined associations between prenatal MeHg exposure and levels of cord blood DNA methylation (DNAm) by meta-analysis in up to seven independent studies (n = 1462) as well as persistence of those relationships in blood from 7 to 8 year-old children (n = 794). In cord blood, we found limited evidence of differential DNAm at cg24184221 in MED31 (β = 2.28 × 10-4, p-value = 5.87 × 10-5) in relat…
The acetylation of spermidine catalyzed by P/CAF regulates its acetyltransferase activity versus histones
2010
Transcriptional regulation in eukaryotes occurs within a chromatin setting and is strongly inhibited by nucleosomal barriers imposed by histone proteins. Among the well-known covalent modifications of chromatin, the reversible acetylation of specific lysine residues of histones, catalyzed by several acetyltransferase and deacetylases, has been linked to many biological processes including transcriptional regulation. Indeed, many transcriptional coactivators possess histone acetyltransferase (HAT) activity (1). Functional interactions between HAT and polyamines have been previously reported. In particular, it has been shown that polyamines facilitate oligomerization of nucleosomal arrays in …

Although French learners studying at BTS level at the National School of Dairy Industry and Biotechnologies (ENILBio) in Poligny have studied English as a second language for several years, they often have difficulty not only understanding it, but more importantly speaking it. As a teacher, it is a problem I am faced with daily and to which I haven’t been able to find explanations or solutions.The aim of this research is to explore the reasons that explain why students often feel embarrassed when they have to speak the language in and outside school, and to question their own practices and representations. This work aims at understanding why BTS students don’t speak English – or speak it li…
