Informācijas sistēmu testēšanas stratēģijas un automatizācija
2015
Maģistra darbā aprakstīts testēšanas stratēģijas izstrādes un ieviešanas process, kā apakšprocesu uzsverot regress testēšanas automatizāciju. Veiksmīgi izstrādāta un ieviesta testēšanas stratēģija ļauj saīsināt projekta kalendāros laikus, samazināt uzturēšanas izmaksas un veicināt gala lietotāju apmierinātību. Maģistra darba ietvaros autore izstrādāja un kontrolēja testēšanas stratēģijas ieviešanas procesu projektā DAS ar kopējo projekta mērķi: minimizēt kvalitātes mazināšanās riskus, veicot testēšanas automatizāciju un uzkrājot zināšanas par sistēmu. Darba autore piedāvāja jaunu testēšanas stratēģiju projektā WP, iekļaujot tajā testu automatizācijas procesa pielāgošanu sistēmas izstrādes p…
Libri di lettura per la scuola primaria: strumenti di promozione e valutazione della reading literacy
2013
A scuola, per insegnare a comprendere un testo, di solito, si propongono agli alunni una serie di compiti da svolgere prevalentemente dopo la lettura, utilizzando un apparato didattico di cui i libri scolastici sono dotati. La definizione di quali abilità di lettura promuovono i testi di scuola primaria costituisce il tema della ricerca. Il campione dell’indagine è composto da 70 libri di lettura; usando una griglia di analisi appositamente costruita, sono state accertate le operazioni richieste all’alunno da esercizi e verifiche sul testo, presenti nell’apparato didattico, che dovrebbero sviluppare negli alunni la capacità di comprensione, interpretazione e valutazione della lettura. I dat…
E-Sports y brecha de género: la percepción de las profesionales españolas
2019
The present paper aims to identify the causes of under-representation of women in E-sports. According to a genre perspective, interest in videogames at the amateur level is quite similar. However, in its professional level, female participation becomes very limited. The fact that physical effort is irrelevant (a requirement for ?traditional sports?) could be considered a variable that would negatively affect greater to equality in the conditions of access and participation of women in electronic sports. Against any predictions, the data on the presence of women are elocuent: few women, with much lower wages than men to remunerate same skills, and a general complaint by the female profession…
Decompressive Craniectomy Improves QTc Interval in Traumatic Brain Injury Patients
2020
Background: Traumatic brain injury (TBI) is commonly associated with cardiac dysfunction, which may be reflected by abnormal electrocardiograms (ECG) and/or contractility. TBI-related cardiac disorders depend on the type of cerebral injury, the region of brain damage and the severity of the intracranial hypertension. Decompressive craniectomy (DC) is commonly used to reduce intra-cranial hypertension (ICH). Although DC decreases ICH rapidly, its effect on ECG has not been systematically studied. The aim of this study was to analyze the changes in ECG in patients undergoing DC. Methods: Adult patients without previously known cardiac diseases treated for isolated TBI with DC were studied. EC…
Problem Transformation Methods with Distance-Based Learning for Multi-Target Regression
2020
Multi-target regression is a special subset of supervised machine learning problems. Problem transformation methods are used in the field to improve the performance of basic methods. The purpose of this article is to test the use of recently popularized distance-based methods, the minimal learning machine (MLM) and the extreme minimal learning machine (EMLM), in problem transformation. The main advantage of the full data variants of these methods is the lack of any meta-parameter. The experimental results for the MLM and EMLM show promising potential, emphasizing the utility of the problem transformation especially with the EMLM. peerReviewed
Decagram-Scale Synthesis of Multicolor Carbon Nanodots: Self-Tracking Nanoheaters with Inherent and Selective Anticancer Properties
2022
Carbon nanodots (CDs) are a new class of carbon-based nanoparticles endowed with photoluminescence, high specific surface area, and good photothermal conversion, which have spearheaded many breakthroughs in medicine, especially in drug delivery and cancer theranostics. However, the tight control of their structural, optical, and biological properties and the synthesis scale-up have been very difficult so far. Here, we report for the first time an efficient protocol for the one-step synthesis of decagram-scale quantities of N,S-doped CDs with a narrow size distribution, along with a single nanostructure multicolor emission, high near-infrared (NIR) photothermal conversion efficiency, and sel…
Intravenous iron therapy in patients with heart failure. A double-edged sword
2013
We read with interest the article of Beck-da-Silva et al., who recently concluded that intravenous (IV) iron seems to be superior over oral supplementation for improving functional capacity of heart failure patients [1]. Irrespective of the study design, involving comparison of functional outcomes between two different means of iron supplementation, we raise some clinical issues about the rationale underlying this investigation. According to the data published by Beck-da-Silva et al., the modest number of patients (n = 23) enrolled in this multicenter investigation had moderate anemia (i.e., hemoglobin concentration comprised between 90 and 120 g/L) but no evidence of iron deficiency, which…
Thiazole Analogues of the Marine Alkaloid Nortopsentin as Inhibitors of Bacterial Biofilm Formation
2020
Anti-virulence strategy is currently considered a promising approach to overcome the global threat of the antibiotic resistance. Among different bacterial virulence factors, the biofilm formation is recognized as one of the most relevant. Considering the high and growing percentage of multi-drug resistant infections that are biofilm-mediated, new therapeutic agents capable of counteracting the formation of biofilms are urgently required. In this scenario, a new series of 18 thiazole derivatives was efficiently synthesized and evaluated for its ability to inhibit biofilm formation against the Gram-positive bacterial reference strains Staphylococcus aureus ATCC 25923 and S. aureus ATCC 6538 a…
Reducing the Time to Detect Cyber Attacks : Combining Attack Simulation With Detection Logic
2021
Cyber attacks have become harder to detect, causing the average detection time of a successful data breach to be over six months and typically costing the target organization nearly four million dollars. The attacks are becoming more sophisticated and targeted, leaving unprepared environments easy prey for the attackers. Organizations with working antivirus systems and firewalls may be surprised when they discover their network has been encrypted by a ransomware operator. This raises a serious question, how did the attacks go undetected? The conducted research focuses on the most common pitfalls regarding late or even non-existent detection by defining the root cause behind the failed detec…
