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 ...
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, ...
Germanene: a novel two-dimensional germanium allotrope akin to graphene and silicene
(IOP Publishing, 2014-09-09)
We have grown an atom-thin, ordered, two-dimensional multi-phase film in situ through germanium molecular beam epitaxy using a gold (111) surface as a substrate. Its growth is similar to the formation of silicene layers ...
Altered expression of Alzheimer's disease-related genes in the cerebellum of autistic patients: a model for disrupted brain connectome and therapy
(Nature Publishing Group, 2014-05)
Autism and Alzheimer's disease (AD) are, respectively, neurodevelopmental and degenerative diseases with an increasing epidemiological burden. The AD-associated amyloid-beta precursor protein-alpha has been shown to be ...
Dobutamine in Paediatric Population: A Systematic Review in Juvenile Animal Models
(Public Library Science, 2014-04-22)
Objective: Although dobutamine is widely used in neonatal clinical practice, the evidence for its use in this specific population is not clear. We conducted a systematic review of the use of dobutamine in juvenile animals ...
A behavior model for blood donors and marketing strategies to retain and attract them
(Univ Sao Paulo, Escola de Enfermagem de Ribeirao Preto, 2014-06)
Objective: analyze and propose a theoretical model that describes blood donor decisions to help staff working in blood banks (nurses and others) in their efforts to capture and retain donors. Methods: analysis of several ...
Addressing students' difficulties with Faraday's law: A guided problem solving approach
(Amer Physical, 2014-06-30)
In traditional teaching, the fundamental concepts of electromagnetic induction are usually quickly analyzed, spending most of the time solving problems in a more or less rote manner. However, physics education research has ...
RESTful Discovery and Eventing for Service Provisioning in Assisted Living Environments
(MDPI, 2014-05)
Service provisioning in assisted living environments faces distinct challenges due to the heterogeneity of networks, access technology, and sensing/actuation devices in such an environment. Existing solutions, such as ...
