Monitoring and analysis of COVID-19 pandemic: the need for an empirical approach
(Frontiers Media SA, 2021-07-08)
Article
Open AccessThe current worldwide pandemic produced by coronavirus disease 2019 (COVID-19) has changed the paradigm of mathematical epidemiology due to the high number of unknowns of this new disease. Thus, the empirical approach has ... -
The impact of prioritisation and dosing intervals on the effects of COVID-19 vaccination in Europe: an agent-based cohort model
(Nature, 2021-09-22)
Article
Open AccessDifferent strategies have been used to maximise the effect of COVID-19 vaccination campaigns in Europe. We modelled the impact of different prioritisation choices and dose intervals on infections, hospitalisations, mortality, ... -
Risk diagrams based on primary care electronic medical records and linked real-time PCR data to monitor local covid-19 outbreaks during the summer 2020: a prospective study including 7,671,862 people in Catalonia
(Frontiers Media SA, 2021-07-05)
Article
Open AccessMonitoring transmission is a prerequisite for containing COVID-19. We report on effective potential growth (EPG) as a novel measure for the early identification of local outbreaks based on primary care electronic medical ... -
Conductance heterogeneities induced by multistability in the dynamics of coupled cardiac gap junctions
(2021-07-01)
Article
Open AccessIn this paper, we study the propagation of the cardiac action potential in a one-dimensional fiber, where cells are electrically coupled through gap junctions (GJs). We consider gap junctional gate dynamics that depend on ... -
ESA/ELGRA Gravity-Related Research Summer School: an introduction to microgravity and hypergravity research for university students
(2021-02)
Article
Restricted access - publisher's policyThe European Low Gravity Research Association (ELGRA) and the European Space Agency (ESA) co-organise since 2016 a Summer School on gravity-related research in the frame of ESA Academy’s Training and Learning Programme. ... -
Analysis of bubble management at different gravity levels by means of an acoustic field
(2021-09)
Article
Open AccessMultiphase flows management is a major challenge in many space applications given the different gravity levels involved. While many of the numerical investigations of liquid-gas phenomena deal with the radial bubble behavior ... -
Acoustic effects on heat transfer on the ground and in microgravity conditions
(2021-10)
Article
Open AccessA critical issue in future long-term space exploration missions is the storage and management of cryogenic propellants. Storage tanks are exposed to extreme temperatures and radiation, which can generate hot spots on the ... -
Schools as a Framework for COVID-19 Epidemiological Surveillance of Children in Catalonia, Spain: A Population-Based Study
(Frontiers Media SA, 2021-09-08)
Article
Open AccessObjective: We describe and analyze the childhood (<18 years) COVID-19 incidence in Catalonia, Spain, during the first 36 weeks of the 2020-2021 school-year and to compare it with the incidence in adults. Methods: Data ... -
Ca2+-CaM dependent inactivation of RyR2 underlies Ca2+ alternans in intact heart
(2021-02-19)
Article
Open AccessRationale: Ca2+ alternans plays an essential role in cardiac alternans that can lead to ventricular fibrillation, but the mechanism underlying Ca2+ alternans remains undefined. Increasing evidence suggests that Ca2+ ... -
The ethical use of high-performance computing and artificial intelligence: fighting COVID-19 at Barcelona Supercomputing Center
(Springer Science and Business Media LLC, 2021-05-06)
Article
Restricted access - publisher's policyThe COVID-19 pandemic has created an extraordinary medical, economic and humanitarian emergency. Artificial intelligence, in combination with other digital technologies, is being used as a tool to support the fight against ... -
Negative-tension instability of scroll waves and Winfree turbulence in the Oregonator model
(2006-10-06)
Article
Open AccessExcitable media support self-organized scroll waves which can be unstable and give rise to three-dimensional wave chaos. Winfree turbulence of scroll waves results from the negative-tension instability of scroll waves; it ... -
Wave pattern dynamics in fluctuating media
(2002-11-01)
Article
Open AccessAnalytical and numerical results on the ordering role of external random fluctuations in excitable systems are presented. Our study focuses on a simple model for excitable systems. Regular waves are created and sustained ...
