Efficient implementation of symplectic implicit Runge-Kutta schemes with simplified Newton iterations
(2017-03-30)
We are concerned with the efficient implementation of symplectic
implicit Runge-Kutta (IRK) methods applied to systems of (non-necessarily
Hamiltonian) ordinary differential equations by means of Newton-like iterations. ...
Reducing and monitoring round-off error propagation for symplectic implicit Runge-Kutta schemes
(2017-01-31)
We propose an implementation of symplectic implicit Runge-Kutta schemes for highly accurate numerical integration of non-stiff Hamiltonian systems based on fixed point iteration. Provided that the computations are done in ...
Sex differences in the aging pattern of renin–angiotensin system serum peptidases
(Biomed Central, 2017-02-03)
Background: Serum peptidases, such as angiotensin-converting enzyme (ACE), angiotensin-converting enzyme-2 (ACE2), neutral endopeptidase (NEP), aminopeptidase N (APN), and aminopeptidase A (APA), are important elements of ...
Potential miRNA Involvement in the Anti-Adipogenic Effect of Resveratrol and Its Metabolites
(Public Library Science, 2017-09-27)
Objective
Scientific research is constantly striving to find molecules which are effective against excessive body fat and its associated complications. Taking into account the beneficial effects that resveratrol exerts ...
Entanglement and extreme spin squeezing of unpolarized states
(IOP Publishing, 2017-01-20)
We present criteria to detect the depth of entanglement in macroscopic ensembles of spin-j particles using the variance and second moments of the collective spin components. The class of states detected goes beyond traditional ...
Poor phenotype-genotype association in a large series of patients with Type III Bartter syndrome
(Public Library Science, 2017-03-13)
Introduction
Type III Bartter syndrome (BS) is an autosomal recessive renal tubule disorder caused by loss-of-function mutations in the CLCNKB gene, which encodes the chloride channel protein ClC-Kb. In this study, we ...
A Component-Based Approach for Securing Indoor Home Care Applications
(MDPI, 2017-01)
eHealth systems have adopted recent advances on sensing technologies together with advances in information and communication technologies (ICT) in order to provide people-centered services that improve the quality of life ...
Virtual Sensor for Kinematic Estimation of Flexible Links in Parallel Robots
(MDPI, 2017-09)
The control of flexible link parallel manipulators is still an open area of research, endpoint trajectory tracking being one of the main challenges in this type of robot. The flexibility and deformations of the limbs make ...
Fabrication and Characterization of Polymer Optical Fibers Doped with Perylene-Derivatives for Fluorescent Lighting Applications
(MDPI, 2017-08)
Four different dye-doped polymer optical fibers (POFs) have been fabricated following a two-step fabrication process of preform extrusion and fiber drawing, using poly-(methyl methacrylate) (PMMA) as host material and dye ...
Characterization of Chromatic Dispersion and Refractive Index of Polymer Optical Fibers
(MDPI, 2017-12-20)
The chromatic dispersion and the refractive index of poly(methyl methacrylate) polymer optical fibers (POFs) have been characterized in this work by using a tunable femtosecond laser and a Streak Camera. The characterization ...
