Tīmekļa lapu veidošanas metožu efektivitātes salīdzinājums
2020
Mūsdienās ir dažnedažādi veidi kā veidot tīmekļa lapas, taču bieži tehnoloģijas tiek izvēlētas pēc gatavo veidņu pieejamības, ietvariem. Tiek dota priekšroka tīmekļa tehnoloģijām, kas ne būt nav efektīvākās lejupielādes laika ziņā. Protams viss ir atkarīgs no tīmekļa lapas mērķa. Vai ir svarīgs resursu lietojums, vai var atļauties neekonomēt resursus. Darbā ir apskatīta HTML, PHP un JS tīmekļa lapu veidošanas tehnoloģiju efektivitāte -lejupielādes laika ziņā pie vienādas funkcionalitātes tīmekļa pārlūkprogrammā.
Effective lifetime measurements in theBs0→K+K−,B0→K+π−andBs0→π+K−decays
2014
Measurements of the effective lifetimes in the B-s(0) -> K+K-, B-0 -> K+pi(-) and B-s(0) -> pi K-+(-) decays are presented using 1.0 fb(-1)of pp collision data collected at a centre-of-mass energy of 7 TeV by the LHCb experiment. The analysis uses a data-driven approach to correct for the decay time acceptance. The measured effective lifetimes are tau(Bs0 -> K+K-) = 1.407 +/- 0.016 (stat) +/- 0.007 (syst) ps, tau(Bs0 -> K+pi-) = 1.524 +/- 0.011 (stat) +/- 0.004 (syst) ps, tau(Bs0 ->pi+K-) = 1.60 +/- 0.06 (stat) +/- 0.01 (syst) ps. This is the most precise determination to date of the effective lifetime in the B-s(0) -> K+K- decay and provides constraints on contributions from physics beyond…
Endosymbiont communities in Bemisia tabaci: a metagenomic approach
2014
Este trabajo es parte de un programa de investigación que tiene como objetivo dilucidar la evolución de las bacterias endosimbiontes utilizando los consorcios insecto-bacteria como modelo. Los diferentes estudios realizados sobre los insectos y sus bacterias endosimbiontes han arrojado luz sobre los cambios ocurridos tras la adquisición de una forma de vida intracelular, así cómo la interacción entre diferentes endosimbiontes formando comunidades endosimbioticas. Dos son los objetivos principales de este trabajo. El primera (capítulos “Portiera y su socio Hamiltonella” y “El tercer pasajero: Cardinium cBtQ1)” trata de analizar y describir las relaciones de la comunidad endosimbiótica en B. …
Reliability of automated optical determination of capillary refill time
2021
The present study is devoted to assessment of automated optical capillary refill time determination by custom developed optoelectronic device prototype. Study comprised fifteen healthy volunteers; To induce capillary refill time changes the hand position challenge was utilized. During rest conditions slight inter-subject variation was observed: T90 (0.75±0.27 s), TSTB (2.20±0.58 s) and temperature at the measurement site (32.21±1.87 Co), however during hand position challenge results were more consistent. Rising hand substantially increased, while lowering slightly decreased capillary refill time. We conclude that automated determination of refill time have high clinical potential, however …
uMemristorToolbox: Open source framework to control memristors in Unity for ternary applications
2020
This paper presents uMemristorToolbox, a novel open source framework that reads and writes non-volatile ternary states to memristors. The Unity (C#) framework is a port of the open source Java project Memristor-Discovery and adds a closed-loop ternary memory controller to enable both PC and real-time embedded ternary applications. We validate the closed-loop ternary memory controller in an embedded system case study with 16 M+SDC Tungsten dopant memristors. We measure an average switching speed of 3 Hz, worst case energy usage of 1 μW per switch, 0.03% random write error and no decay in (non-volatile) state retention after 15 minutes. We conclude with observations and open questions when wo…
Sensitive Screening of New Psychoactive Substances in Serum Using Liquid Chromatography-Quadrupole Time-of-Flight Mass Spectrometry.
2021
Abstract Analysis of new psychoactive substances (NPS) still poses a challenge for many institutions due to the number of available substances and the constantly changing drug market. Both new and well-known substances keep appearing and disappearing on the market, making it hard to adapt analytical methods in a timely manner. In this study we developed a qualitative screening approach for serum samples by means of liquid chromatography--quadrupole time-of-flight mass spectrometry. Samples were measured in data-dependent auto tandem mass spectrometry mode and identified by fragment spectra comparison, retention time and accurate mass. Approximately 500 NPS, including 195 synthetic cannabino…
Measuring the Rate of Information Transfer in Point-Process Data: Application to Cardiovascular Interactions
2021
We present the implementation to cardiovascular variability of a method for the information-theoretic estimation of the directed interactions between event-based data. The method allows to compute the transfer entropy rate (TER) from a source to a target point process in continuous time, thus overcoming the severe limitations associated with time discretization of event-based processes. In this work, the method is evaluated on coupled cardiovascular point processes representing the heartbeat dynamics and the related peripheral pulsation, first using a physiologically-based simulation model and then studying real point-process data from healthy subjects monitored at rest and during postural …
Prothrombinase-Induced Clotting Time Assay for Determination of the Anticoagulant Effects of Unfractionated and Low-Molecular-Weight Heparins, Fondap…
2008
The prothrombinase-induced clotting time assay (PiCT, Pentapharm, Basel, Switzerland) is a clotting assay sensitive to factor Xa and factor IIa inhibitors. It is based on the addition of factor Xa and snake venom RVV-V (Russell viper venom factor V activator) specifically activating factor V and phospholipids to platelet-poor plasma. Following an incubation time, the mixture is recalcified and the clotting time is determined. An almost linear dose-response and high sensitivity of the assay for unfractionated heparin (UFH), low-molecular-weight heparins (LMWHs), r-hirudin, and argatroban was found. Fondaparinux showed a nonlinear dose-response. By using ex vivo samples, the following Pearson…
Correction: Phylogeny of the Eurasian Wren Nannus troglodytes (Aves: Passeriformes: Troglodytidae) reveals deep and complex diversification patterns …
2020
The Mediterranean Basin represents a Global Biodiversity Hotspot where many organisms show high inter- and intraspecific differentiation. Extant phylogeographic patterns of terrestrial circum-Mediterranean faunas were mainly shaped through Pleistocene range shifts and range fragmentations due to retreat into different glacial refugia. Thus, several extant Mediterranean bird species have diversified by surviving glaciations in different hospitable refugia and subsequently expanded their distribution ranges during the Holocene. Such a scenario was also suggested for the Eurasian Wren (Nannus troglodytes) despite the lack of genetic data for most Mediterranean subspecies. Our phylogenetic mult…
Mutual learning: exploring collaboration, knowledge and roles in the development of recovery-oriented services. A hermeneutic-phenomenological study
2021
ABSTRACT Purpose The concept of recovery is commonly described as multifaceted and contested in the field of mental health and substance abuse. The aim of this study is to explore how understandings of recovery and recovery orientation of services are developed through daily practices and collaboration between service users and professionals. Methods Eight pairs of participants were interviewed together, in accordance with the dyadic interview method. The dyads/pairs consisted of service users and professional helpers. A collaborative hermeneutic-phenomenological analysis was used to analyse data. Results Data were analysed into three overarching and entangled themes, exploring how recovery…
