Defect and structural imperfection effects on the electronic properties of BiTeI surfaces
(IOP Publishing, 2014-07-24)
The surface electronic structure of the narrow-gap seminconductor BiTeI exhibits a large Rashba-splitting which strongly depends on the surface termination. Here we report on a detailed investigation of the surface morphology ...
European economic crisis and health inequities: research challenges in an uncertain scenario
(Biomed Central, 2014-07-25)
Progressive Decrease in the Potential Usefulness of Meningococcal Serogroup B Vaccine (4CMenB, Bexsero (R)) in Gipuzkoa, Northern Spain
(Public Library Science, 2014-12-26)
The effectiveness of a vaccine is determined not only by the immunogenicity of its components, but especially by how widely it covers the disease-causing strains circulating in a given region. Because vaccine coverage ...
Self-Organized Criticality, Plasticity and Sensorimotor Coupling. Explorations with a Neurorobotic Model in a Behavioural Preference Task
(Public Library of Science, 2015-02-23)
During the last two decades, analysis of 1/f noise in cognitive science has led to a considerable progress in the way we understand the organization of our mental life. However, there is still a lack of specific models ...
Nonlinear magnetic vortex dynamics in a circular nanodot excited by spin-polarized current
(Springer International Publishing, 2014-08-08)
We investigate analytically and numerically nonlinear vortex spin torque oscillator dynamics in a circular magnetic nanodot induced by a spin-polarized current perpendicular to the dot plane. We use a generalized nonlinear ...
A uniform phase representation for the harmonic model in speech synthesis applications
(Springer International Publishing, 2014-10-16)
Feature-based vocoders, e.g., STRAIGHT, offer a way to manipulate the perceived characteristics of the speech signal in speech transformation and synthesis. For the harmonic model, which provide excellent perceived quality, ...
Plastidic Phosphoglucose Isomerase Is an Important Determinant of Starch Accumulation in Mesophyll Cells, Growth, Photosynthetic Capacity, and Biosynthesis of Plastidic Cytokinins in Arabidopsis
(Public Library of Science, 2015-03-26)
Phosphoglucose isomerase (PGI) catalyzes the reversible isomerization of glucose-6-phosphate and fructose-6-phosphate. It is involved in glycolysis and in the regeneration of glucose-6-P molecules in the oxidative pentose ...
Physiological modules for generating discrete and rhythmic movements: Component analysis of EMG signals
(Frontiers Research Foundation, 2015-01-09)
A central question in Neuroscience is that of how the nervous system generates the spatiotemporal commands needed to realize complex gestures, such as handwriting. A key postulate is that the central nervous system (CNS) ...
A Data Dropout Compensation Algorithm Based on the Iterative Learning Control Methodology for Discrete-Time Systems
(Hindawi Publishing Corporation, 2015)
This paper deals with the convergence of a remote iterative learning control system subject to data dropouts. The system is composed by a set of discrete-time multiple input-multiple output linear models, each one with its ...
Mindfulness training for reducing anger, anxiety, and depression in fibromyalgia patients
(Frontiers Reseach Foundation, 2015-01-12)
Fibromyalgia is a disabling syndrome. Results obtained with different therapies are very limited to date.The goal of this study was to verify whether the application of a mindfulnessbased training program was effective in ...
