3D reconstruction does not improve agreement and results in an increase in surgical indications in proximal humeral fractures
(2018-12-01)
Article
Accés obertThe objective of this study is to analyze the effect of different imaging modalities in treatment decision making in proximal humeral fractures. After evaluation of 116 consecutive proximal humeral fractures, observers ... -
A balance index for phylogenetic trees based on rooted quartets
(2019-06-17)
Article
Accés obertWe define a new balance index for rooted phylogenetic trees based on the symmetry of the evolutive history of every set of 4 leaves. This index makes sense for multifurcating trees and it can be computed in time linear in ... -
A data mining approach for Visual and Analytic identification of neurorehabilitation ranges in traumatic brain injury cognitive rehabilitation
(2015-01-15)
Article
Accés restringit per decisió de l'autorTraumatic brain injury (TBI) is a critical public health and socioeconomic problem throughout the world. Cognitive rehabilitation (CR) has become the treatment of choice for cognitive impairments after TBI. It consists of ... -
A data science approach for spatiotemporal modelling of low and resident air pollution in Madrid (Spain): implications for epidemiological studies
(2019-05-01)
Article
Accés obertModel developments to assess different air pollution exposures within cities are still a key challenge in environmental epidemiology. Background air pollution is a long-term resident and low-level concentration pollution ... -
A hazard ratio was estimated by a ratio of median survival times, but with considerable uncertainty
(2014-10-01)
Article
Accés obertObjectives: To evaluate the empirical concordance between the hazard ratio (HR) and the median ratio (MR) in survival cancer studies. Study Design and Setting: We selected all cancer survival articles from the New England ... -
A likelihood ratio approach for identifying three-quarter siblings in genetic databases
(2021-01-15)
Article
Accés obertThe detection of family relationships in genetic databases is of interest in various scientific disciplines such as genetic epidemiology, population and conservation genetics, forensic science, and genealogical research. ... -
A low dimensional surrogate model for a fast estimation of strain in the thrombus during a thrombectomy procedure
(Elsevier, 2023-01-01)
Article
Accés restringit per política de l'editorialBackground Intra-arterial thrombectomy is the main treatment for acute ischemic stroke due to large vessel occlusions and can consist in mechanically removing the thrombus with a stent-retriever. A cause of failure of the ... -
A lower olfactory capacity Is related to higher circulating concentrations of endocannabinoid 2-arachidonoylglycerol and higher body mass index in women
(2016)
Article
Accés obertThe endocannabinoid (eCB) system can promote food intake by increasing odor detection in mice. The eCB system is over-active in human obesity. Our aim is to measure circulating eCB concentrations and olfactory capacity in ... -
A mathematical model coupling tumor growth and angiogenesis
(Public Library of Science (PLOS), 2016-02-18)
Article
Accés obertWe present a mathematical model for vascular tumor growth. We use phase fields to model cellular growth and reaction-diffusion equations for the dynamics of angiogenic factors and nutrients. The model naturally predicts ... -
A mathematical model for the COVID-19 pandemic in Tokyo through changing point calculus
(Multidisciplinary Digital Publishing Institute, 2023-11-12)
Article
Accés obertThe great social and economic impact that the COVID-19 pandemic has had on a global level has encouraged the development of new mathematical models that make it possible to better manage this and future pandemics. Here, ... -
A mathematical model of tumour angiogenesis: growth, regression and regrowth
(2017-01)
Article
Accés obertCancerous tumours have the ability to recruit new blood vessels through a process called angiogenesis. By stimulating vascular growth, tumours get connected to the circulatory system, receive nutrients and open a way to ... -
A multi-scale clutch model for adhesion complex mechanics
(Public Library of Science (PLOS), 2023-07-14)
Article
Accés obertCell-matrix adhesion is a central mechanical function to a large number of phenomena in physiology and disease, including morphogenesis, wound healing, and tumor cell invasion. Today, how single cells respond to different ... -
A multiparametric advection-diffusion reduced-order model for molecular transport in scaffolds for osteoinduction
(Springer Nature, 2022-05-05)
Article
Accés obertScaffolds are microporous biocompatible structures that serve as material support for cells to proliferate, differentiate and form functional tissue. In particular, in the field of bone regeneration, insertion of scaffolds ... -
A network algorithm for the X chromosomal exact test for Hardy–Weinberg equilibrium with multiple alleles
(2021-07-01)
Article
Accés obertStatistical methodology for testing the Hardy-Weinberg equilibrium at X chromosomal variants has recently experienced considerable development. Up to a few years ago, testing X chromosomal variants for equilibrium was ... -
A neural networks approach to aerofoil noise prediction
(2009)
Report de recerca
Accés obertA neural network noise prediction model for a turbulent boundary layer noise mechanism has been created using a feed forward multilayer perceptron and a noise spectrum database collected from a family of NACA 0012 areofoils. ... -
