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 ...
Image-Based Delineation and Classification of Built Heritage Masonry
(MDPI, 2014-03)
Fundacion Zain is developing new built heritage assessment protocols. The goal is to objectivize and standardize the analysis and decision process that leads to determining the degree of protection of built heritage in the ...
Epitope mapping of antibodies to alpha-synuclein in LRRK2 mutation carriers, idiopathic Parkinson disease patients, and healthy controls
(Frontiers Research Foundation, 2014-07-15)
Alpha-synuclein (Snca) plays a major role in Parkinson disease (PD). Circulating anti-Snca antibodies has been described in PD patients and healthy controls, but they have been poorly characterized. This study was designed ...
