Multi-resolution quality-based video coding system for DASH scenarios
2021
Today, more than 85% of Internet traffic has a multimedia component. Video streaming occupies a large part of this percentage mainly because this type of content is provided by the most used applications on the Internet (e.g. Twitch, TikTok, Disney+, YouTube, Netflix, etc.). Most of these platforms use HTTP Adaptive Streaming (HAS) to send this media content to end users in order to ensure a good quality of experience (QoE). But, this QoE should be guaranteed from the video to be transmitted, i.e., the video should have an adequate quality by minimizing the bitrate before transmission. In order to solve this issue, we present a system capable of encoding a video in several resolutions given…
Autonomy and patient prisoners
2007
Los autores estudian una reciente sentencia de la Sala 3ª del Tribunal Supremo en la que se declara la responsabilidad patrimonial de la Administración por la muerte de un paciente preso. Se analizan los argumentos de la Sala desde una perspectiva jurídica, ética, médica y social. Concluyen que: 1: la Administración no está legitimada para imponer tratamientos médicos a los reclusos, salvo que medie riesgo grave y cierto para su vida, incapacidad para decidir o riesgo para la salud de terceros; 2: que la sentencia supone un ataque frontal a la autonomía de los pacientes presos en la toma de decisiones sanitarias que les afecten; 3: que desde un punto de vista médico es discriminatoria, ya q…
Twenty-year trends in the prevalence of Down syndrome and other trisomies in Europe : impact of maternal age and prenatal screening
2013
This study examines trends and geographical differences in total and live birth prevalence of trisomies 21, 18 and 13 with regard to increasing maternal age and prenatal diagnosis in Europe. Twenty-one population-based EUROCAT registries covering 6.1 million births between 1990 and 2009 participated. Trisomy cases included live births, fetal deaths from 20 weeks gestational age and terminations of pregnancy for fetal anomaly. We present correction to 20 weeks gestational age (ie, correcting early terminations for the probability of fetal survival to 20 weeks) to allow for artefactual screening-related differences in total prevalence. Poisson regression was used. The proportion of births in …

Singular Neumann (p, q)-equations
2019
We consider a nonlinear parametric Neumann problem driven by the sum of a p-Laplacian and of a q-Laplacian and exhibiting in the reaction the competing effects of a singular term and of a resonant term. Using variational methods together with suitable truncation and comparison techniques, we show that for small values of the parameter the problem has at least two positive smooth solutions.
Multiple solutions for (p,2)-equations at resonance
2019
We consider a nonlinear nonhomogeneous Dirichlet problem driven by the sum of a p-Laplacian and a Laplacian and a reaction term which is (p− 1)-linear near ±∞ and resonant with respect to any nonprincipal variational eigenvalue of (−∆p, W01,p(Ω)). Using variational tools together with truncation and comparison techniques and Morse Theory (critical groups), we establish the existence of six nontrivial smooth solutions. For five of them we provide sign information and order them.
A cultural comparison study of smartphone adoption in Uzbekistan, South Korea and Turkey
2017
Smartphone popularity is increasing due to the technological advances that mean manufacturers can make more sophisticated devices, and telecommunication companies can provide better connections. Gartner reported that 403 million smartphones were sold in the fourth quarter of 2015, a 9.7% increase over the same period in 2014. It is a common perception that users tend to utilise advanced technology to increase productivity. However, there are studies indicating quite opposite or alternatively slow rates of adoption. To avoid this, companies invest in studying consumer behaviour. The purpose of the study is to examine the effects of drivers and cultural differences on smartphone acceptance in…
The origin of lecithodesmus (Digenea: Campulidae) based on ND3 gene comparison
2000
Species of Lecithodesmus (Campulidae) occur almost exclusively in baleen whales throughout a wide geographical distribution. Other campulids occur only in odontocetes and, secondarily, in pinnipeds and the sea otter. Therefore, the ancestor of Lecithodesmus might have either cospeciated with mysticetes during the early divergence of mysticete and odontocete cetaceans or originated later via host switching. We evaluate both possibilities based on a phylogenetic analysis. The ND3 mitochondrial gene sequence of a species of Lecithodesmus was included in a previous partial molecular phylogeny of the Campulidae. Fasciola hepatica and Dicrocoelium dendriticum were used as outgroups. Maximum parsi…
Gianfrancesco Maineri, Paolo da San Leocadio i la gènesi d?un model de Crist portacreu
2020
[CA] El present article es centra en la vinculació entre els diversos exemplars de Crist portacreu de Gianfrancesco Maineri i els homònims de Paolo da San Leocadio. A través de diverses comparacions, tractarà d¿explicar-se la gènesi d¿aquest model, aportant, a més, dades que permetran una millor classificació dels exemplars leocadians. Finalment, es realitzen una sèrie de reflexions entorn de l¿hipotètic retorn de San Leocadio a Itàlia (1485-1489) i a la seua possible vinculació amb Maineri.
El consentimiento informado en los pacientes privados de libertad
2013
Fundamento y objetivo: El consentimiento informado (CI) médico constituye hoy el pilar fundamental sobre el que se asienta la asistencia sanitaria a la población. Cualquier persona competente y capaz para tomar decisiones puede dar o negar su permiso para cualquier intervención médica que le afecte, incluso una intervención que vaya a salvar su vida, siempre que esa decisión no amenace intereses de terceros. A pesar de este principio general hay un grupo de personas, que son los presos, que tienen restringida su aplicación y no pueden decidir libremente sobre aceptar o rechazar un tratamiento médico en casos extremos, cuando su salud o su vida corran peligro. El objetivo del trabajo es resp…
