2015
Maģistra darbs ir uzrakstīts latviešu un angļu valodās, datorsalikumā uz 48 lapām. Tas satur 34 attēlus, 6 tabulas, 37 atsauces uz literatūras avotiem. Mērķis: izveidot spektrāli maināmu gaismas avotu, kas uzlabotu diabēta radītu tīklenes bojājumu un citu tīklenes struktūru kompjūter-diagnostiku. Metode: Spektrāli maināms gaismas avots, kas ir balstīts uz digitālās mikrospoguļu ierīces (DMD) un modificētas fundus kameras, kas komplektēti ar monohromatisku kameru tīklenes attēlu iegūšanai. Tīklenes attēli uzņemti, gan no vesela pētījuma dalībnieka, gan diabēta pacientiem. Secinājumi: Ar spektrāli maināmu gaismas avotu ar optimizētiem apgaismojumiem var uzņemt uzlabota kontrasta tīklenes stru…
Investigation of the Sympathetic Regulation in Delayed Onset Muscle Soreness: Results of an RCT
2021
Sports-related pain and injury is directly linked to tissue inflammation, thus involving the autonomic nervous system (ANS). In the present experimental study, we disable the sympathetic part of the ANS by applying a stellate ganglion block (SGB) in an experimental model of delayed onset muscle soreness (DOMS) of the biceps muscle. We included 45 healthy participants (female 11, male 34, age 24.16 ± 6.67 years [range 18–53], BMI 23.22 ± 2.09 kg/m2) who were equally randomized to receive either (i) an SGB prior to exercise-induced DOMS (preventive), (ii) sham intervention in addition to DOMS (control/sham), or (iii) SGB after the induction of DOMS (rehabilitative). The aim of the study was t…
Behind the scenes of artificial intelligence: a study of micro-work platforms in France
2019
Este artículo es una versión resumida del informe “Le Micro-travail en France. Derrière l’automatisation de nouvelles précarités au travail?» This article is a summarized version of the report "Le Micro-travail en France. Derrière l’automatisation de nouvelles précarités au travail?" .; International audience; Micro-work internet services allocate small, standardized tasks of data generation and annotation to crowds of providers. The outputs are mainly used to produce artificial intelligence solutions. It is an exemplary instance of the “platformization” of the economy, and of the transformations of labour that digital technologies bring about. To uncover the conditions under which micro-wo…
Stochastic gravito-inertial modes discovered by CoRoT in the hot Be star HD 51452
2012
International audience; Context. Be stars are rapidly rotating stars with a circumstellar decretion disk. They usually undergo pressure and/or gravity pulsation modes excited by the κ-mechanism, i.e. an effect of the opacity of iron-peak elements in the envelope of the star. In the Milky Way, p-modes are observed in stars that are hotter than or equal to the B3 spectral type, while g-modes are observed at the B2 spectral type and cooler. Aims. We observed a B0IVe star, HD 51452, with the high-precision, high-cadence photometric CoRoT satellite and high-resolution, ground-based HARPS and SOPHIE spectrographs to study its pulsations in great detail. We also used the lower resolution spectra a…
Pre-sleep arousal and sleep quality during the COVID-19 lockdown in Italy
2021
Abstract Objective The COVID-19 pandemic has strongly affected daily habits and psychological wellbeing, and many studies point to large modifications in several sleep and sleep-related domains. Nevertheless, pre-sleep arousal during the pandemic has been substantially overlooked. Since hyperarousal represents one of the main factors for the development and the perpetuation of chronic insomnia disorder, the assessment of variables associated with high levels of pre-sleep arousal during the pandemic is clinically relevant. The study aimed to assess the prevalence and predictors of perceived sleep quality and pre-sleep arousal in an Italian sample during the COVID-19 lockdown. Methods We used…
Aizsarglietu stāstījumu folklora Latgalē (pēc 2018. un 2019. gada lauka pētījumu materiāliem)
2019
Bakalaura darba tēma ir “Aizsarglietu stāstījumu folklora Latgalē (pēc 2018. un 2019. gada lauka pētījumu materiāliem)”. Bakalaura darba mērķis bija noskaidrot, kas ir raksturīgs aizsarglietu stāstījumu folklorai Latgalē, kāda ir tās specifika, vai un kā ir transformējušās ar aizsarglietām saistītās latviešu tautas tradīcijas, salīdzinot ar latviešu folkloras materiālu. Darbs sastāv no ievada, trim nodaļām un, secinājumiem. Pirmajā nodaļā tika analizēti aizsarglietu stāstījumi, kas vēsta par mājas aizsardzību (māju, īpašumu aizsargājošiem augiem, ornamentālajām zīmēm, baznīcā svētītajām aizsarglietām), un tika noskaidroti aizsarglietu izmantošanas dažādie nolūki. Otrajā nodaļā tika raksturo…
Institutional arrangements for sustainable development: Cases from the Navarra Province (Spain).
2015
After more than 20 years of the Earth Summit, Sustainable development is still recognized as one of the main challenges of the XXIst century. World leaders are putting new emphasis on the need to resolve urgent environmental challenges underlining their link with the wellbeing of humankind and the very conditions that made life possible on the planet. We are immersed in complex socio-ecological systems where sectoral or simplified responses are not adequate. A more systemic vision is imperative to effectively address the challenges faced. New approaches are being developed to integrate social, environmental and economic concerns in all human activities. Particular attention is given to deco…
Fault-proneness of open source software: Exploring its relations to internal software quality and maintenance process
2013
The goal of this study is to explore how fault-proneness of open source software (OSS) could be explained in terms of internal quality attributes and maintenance process metrics. We reviewed earlier studies and performed a multiple case study of eight Java-based projects based on data available in the Source Forge repository. Overall, we studied 342 re- leases of those systems. As is usual, software quality was regarded as a set of internal and external quality attributes. A to- tal of 76 internal quality attributes were measured from the source code of the selected systems via the tool SoftCalc. Two external quality attributes contributing to fault-proneness were in turn obtained from the …
Are they different? affect, feeling, emotion, sentiment, and opinion detection in text
2014
A major limitation in the automatic detection of affect, feelings, emotions, sentiments, and opinions in text is the lack of proper differentiation between these subjective terms and understanding of how they relate to one another. This lack of differentiation not only leads to inconsistency in terminology usage but also makes the subtleties and nuances expressed by the five terms difficult to understand, resulting in subpar detection of the terms in text. In light of such limitation, this paper clarifies the differences between these five subjective terms and reveals significant concepts to the computational linguistics community for their effective detection and processing in text.
