Anatomical location of LPA1 activation and LPA phospholipid precursors in rodent and human brain
(John Wiley & Sons, 2015-04-10)
El ácido lisofosfatídico (LPA) es una molécula de señalización que se une a seis receptores acoplados a proteínas G conocidos: LPA1 -LPA6 . El LPA evoca varias respuestas en el SNC, entre ellas el desarrollo y plegamiento ...
An efficient implementation of kernel density estimation for multi-core and many-core architectures
(Sage, 2015-03-16)
Kernel density estimation (KDE) is a statistical technique used to estimate the probability density function of a sample set with unknown density function. It is considered a fundamental data-smoothing problem for use with ...
An isoperimetric-type inequality for electrostatic shell interactions for Dirac operators
(Springer Nature, 2015-10-17)
Abstract: In this article we investigate spectral properties of the coupling H +Vλ, where
H = −iα ·∇ +mβ is the free Dirac operator in R3 , m > 0 and Vλ is an electrostatic shell
potential (which depends on a parameter ...
Anatomical distribution of lipids in human brain cortex by imaging mass spectrometry
(Springer Verlag, 2011-01-28)
[ES] Las imágenes de masa molecular de los tejidos estarán sesgadas si las diferencias en las propiedades fisicoquímicas del microentorno afectan a la intensidad de los espectros. Para abordar esta cuestión, hemos realizado ...
Analysis of the regimes in the scanner-based laser hardening process
(Elsevier, 2016-10-10)
Laser hardening is becoming a consolidated process in different industrial sectors such as the automotive industry or in the die and mold industry. The key to ensure the success in this process is to control the surface ...
Analysis of the effect of temperature reaction time on yields, compositions and oil quality in 3 catalytic and non-catalytic lignin solvolysis in a formic acid/water media using experimental design.
(Elsevier, 2017-03-01)
[EN] The catalytic solvolysis of Norway spruce (Picea abies L.) lignin in a formic acid/water media was explored at different temperatures and reaction times (283–397 °C and 21–700 min, respectively). Non-catalyzed experiments ...
ECG-based pulse detection during cardiac arrest using random forest classifier
(Springer, 2019)
Sudden cardiac arrest is one of the leading causes of death in the industrialized world. Pulse detection is essential for the recognition of the arrest and the recognition of return of spontaneous circulation during therapy, ...
Analysis of electrical and thermal models and modeling techniques for polymer electrolyte membrane fuel cells
(Elsevier, 2019-07-27)
Polymeric Electrolyte Membrane Fuel Cell (PEMFC) modeling considering thermal and electrical behavior in a coupled manner is a key aspect when evaluating new designs, materials, physical phenomena or control strategies. ...
Analytical and numerical approach of an End Notched Flexure test configuration with an inserted roller for promoting mixed mode I/II
(Elsevier, 2015-06-22)
A test configuration for studying mixed-mode is analyzed analytically and numerically. It is based on the End Notched Flexure test, inserting a roller in the cracked part in order to promote mixed mode I/II. The analytical ...
Automatic Cardiac Rhythm Classification with Concurrent Manual Chest Compressions
(IEEE, 2019-08-13)
Electrocardiogram (EKG) based classification of out-of-hospital cardiac arrest (OHCA) rhythms is
important to guide treatment and to retrospectively elucidate the effects of therapy on patient response.
OHCA rhythms are ...
