Regresa testēšanas automatizācijas rīka izvēle darbvirsmas lietotnēm
2015
Programmatūras testēšanai mūsdienās ir arvien lielāka nozīme, tiek izmantotas dažādas testēšanas metodes un rīki. Uzņēmumi, kas nodarbojas ar programmatūras izstrādi, arvien vairāk sāk skatīties uz iespējām automatizēt vismaz daļu no uzņēmuma ierastā darba, ja šis ierastais darbs sastāv no atkārtoti veicamām darbībām. Darba mērķis ir atrast uzņēmuma SIA ZZ Dats darbvirsmas lietojumprogrammu testēšanas vajadzībām atbilstošāko regresa testu automatizācijas rīku. Darba apjoms - 64 lpp., 49 attēli, 3 tabulas, 21 bibliogrāfiskā norāde, 1 pielikums. Darbs sastāv no teorētiskās un praktiskās daļas. Teorētiskajā daļā aprakstīta regresa testēšana un kāpēc tā būtu jāveic, kā arī aplūkoti dažādi rīki,…
Fitting linear models and generalized linear models with large data sets in R
2009
We present an estimating algorithm to fit linear and generalized linear models not involving the QR decomposition. Some new R functions are presented and discussed. For large data sets, comparisons with respect to the well-known lm() and glm(), as well as to biglm() and bigglm() from the package biglm, show that the proposed functions speed up computation while preserving numerical stability and accuracy
Regularization operators for natural images based on nonlinear perception models.
2006
Image restoration requires some a priori knowledge of the solution. Some of the conventional regularization techniques are based on the estimation of the power spectrum density. Simple statistical models for spectral estimation just take into account second-order relations between the pixels of the image. However, natural images exhibit additional features, such as particular relationships between local Fourier or wavelet transform coefficients. Biological visual systems have evolved to capture these relations. We propose the use of this biological behavior to build regularization operators as an alternative to simple statistical models. The results suggest that if the penalty operator take…
Epigenetic regulation of stemness maintenance in the neurogenic niches
2015
In the adult mouse brain, the subventricular zone lining the lateral ventricles and the subgranular zone in the dentate gyrus of the hippocampus are two zones that contain neural stem cells (NSCs) with the capacity to give rise to neurons and glia during the entire life of the animal. Spatial and temporal regulation of gene expression in the NSCs population is established and maintained by the coordinated interaction between transcription factors and epigenetic regulators which control stem cell fate. Epigenetic mechanisms are heritable alterations in genome function that do not involve changes in DNA sequence itself but that modulate gene expression, acting as mediators between the environ…
Multiplex RT-PCR Expression Analysis of Developmentally Important Genes in Individual Mouse Preimplantation Embryos and Blastomeres1
2009
We have developed a microfluidic chip-based qualitative assay for sensitive (10 RNA copies) detection of multiple transcripts in single cells. We determined the expression patterns of 17 developmentally important genes and isoforms in individual mouse preimplantation embryos from superovulated matings and blastomeres. The ubiquitously expressed histone variant H3f3a and the transcription factor Pou5f1 generated mRNA-derived products in all analyzed (1-cell, 2-cell, 4-cell, and morula stage) embryos and in all analyzed blastomeres from 16-cell embryos, indicating a uniform reactivation of pluripotency gene expression during mouse preimplantation development. In contrast, mRNA expression of d…
Role of non-coding RNAs as biomarkers of deleterious cardiovascular effects in sepsis.
2021
The mechanisms occurring during sepsis that produce an increased risk of cardiovascular (CV) disease (CVD) are poorly understood. Even less information exists regarding CV dysfunction as a complication of sepsis, particularly for sepsis-induced cardiomyopathy. However, recent research has demonstrated that non-coding RNAs, including microRNAs, long non-coding RNAs, and circular RNAs, play a crucial role in genetic reprogramming, gene regulation, and inflammation during the development of CVD. Here we describe experimental findings showing the importance of non-coding RNAs mediating relevant mechanisms underlying CV dysfunction after sepsis, so contributing to sepsis-induced cardiomyopathy. …
Impacts of tailored, rehabilitation nursing care on functional ability and quality of life in hospitalized elderly patients after rib fractures
2021
Objectives: We aimed to analyze the effects of a tailored rehabilitation nursing care program on functional ability and quality of life in patients with conservative treatment for rib fractures. Design: Randomized controlled trial. Setting: Inpatient rehabilitation hospital. Subjects: Rib fracture patients treated conservatively were randomized into two groups (experimental and control group). Interventions: Patients in control group received Treatment as Usual (TAU) and patients included in experimental group received TAU and an added tailored rehabilitation nursing care program (RNT). Main measures: At baseline, and end of hospitalization treatment, the functional ability was assessed wit…
Evaluating the feasibility of the Italian version of the computerized interactive remediation of cognition training for schizophrenia (circuits)
2020
Background: Circuits is a computerized cognitive remediation program for individuals with schizophrenia. this study aimed to evaluate the feasibility of the italian version of circuits. MethODs: Feasibility was measured through ad-hoc questionnaires in a non-clinical sample (N.=30; target-score 70%; study 1); in patients with schizophrenia (N.=5; target-score 60%; study 2) and cr therapists (N.=3; target-score 60%; study 2). study 3 was a pilot study investigating: 1) enrolment, compliance, and retention rates; 2) satisfaction; 3) potential post-treatment and follow-up improvements in patients with schizophrenia (N.=20). these results were used to estimate sample size and feasibility for a …

Kvalifikācijas darbā ir izstrādāta Android lietotne ceļa locītavu rehabilitācijai. Tā sastāv no divām daļām, kas katra paredzēta savai lietotāju grupai. Pirmā daļa ir paredzēta pacientam, kurš veic rehabilitācijas procesu. Tā komunicē ar iegulto ierīci, kas tiek stiprināta pie pacienta locītavas un ar sensoru palīdzību raida informāciju uz Android ierīci. Tā nodrošina iespēja sekot līdzi vingrinājumu pildīšanas kvalitātei reāllaikā, papildus sūtot datus ārstam. Savukārt otrā daļa ir paredzēta ārstam.

Los predictores clave de la reincidencia en participantes en un programa de intervención para agresores de pareja: un análisis de supervivencia
2020
ABSTRACT Strategies to reduce intimate partner violence against women (IPVAW) can be targeted at different levels. Batterer intervention programs (BIPs) are among the main treatment approaches for IPVAW offenders. The most common outcome used in the evaluation of BIP effectiveness is recidivism. Efforts to increase BIP effectiveness in reducing recidivism should focus on key predictive variables of this outcome. The aim of this study was to identify key predictors of official recidivism from a large set of variables drawn from a sample of IPVAW offenders court-mandated to a community-based BIP (N = 393), with a follow-up period of between 0 and 69 months. To this end, a survival analysis wa…
