Microwave Resonant and Zero-Field Absorption Study of Doped Magnetite Prepared by a Co-Precipitation Method
(MDPI, 2014-06)
Fe3O4 and ZnxFe3-xO4 pure and doped magnetite magnetic nanoparticles (NPs) were prepared in aqueous solution (Series A) or in a water-ethyl alcohol mixture (Series B) by the co-precipitation method. Only one ferromagnetic ...
Subtypes of Patients Experiencing Exacerbations of COPD and Associations with Outcomes
(Public Library Science, 2014-06-03)
Chronic obstructive pulmonary disease (COPD) is a complex and heterogeneous condition characterized by occasional exacerbations. Identifying clinical subtypes among patients experiencing COPD exacerbations (ECOPD) could ...
Effectiveness of a Multi-Component Smoking Cessation Support Programme (McSCSP) for Patients with Severe Mental Disorders: Study Design
(MDPI, 2014-01)
Only a few studies have examined the efficacy and safety of smoking cessation programmes in patients with mental disorders. The aim of this paper is to describe in detail the methodology used in the study as well as the ...
Hole-Phonon Relaxation and Photocatalytic Properties of Titanium Dioxide and Zinc Oxide: First-Principles Approach
(Hindawi Publishing, 2014)
First-principles calculations for the temporal characteristics of hole-phonon relaxation in the valence band of titanium dioxide and zinc oxide have been performed. A first-principles method for the calculations of the ...
von Neumann spin measurements with Rashba fields
(IOP Publishing, 2014-01-10)
We show that dynamics in the spin-orbit coupling field simulate the von Neumann measurement of a particle spin. We demonstrate how the measurement influences the spin and coordinate evolution of a particle by comparing two ...
Hyers-Ulam-Rassias Stability of Functional Differential Systems with Point and Distributed Delays
(Hindawi Publishing Corporation, 2015)
This paper investigates stability and asymptotic properties of the error with respect to its nominal version of a nonlinear time-varying perturbed functional differential system subject to point, finite-distributed, and ...
Effects of Small-Sided Games vs. Interval Training in Aerobic Fitness and Physical Enjoyment in Young Elite Soccer Players
(Public Library Science, 2015-09-02)
The purpose of this study was to compare the effects of Small-Sided Games (SSG) vs. Interval Training (IT) in soccer training on aerobic fitness and physical enjoyment in youth elite soccer players during the last 8 weeks ...
Neurolinguistic measure of typological effects in multilingual transfer: introducing an ERP methodology
(Frontiers Media, 2015-08-07)
This article has two main objectives. First, we offer an introduction to the subfield of generative third language (L3) acquisition. Concerned primarily with modeling initial stages transfer of morphosyntax, one goal of ...
The Spanish corporate structure through interlocking directorates
(Instituto de Economía Aplicada a la Empresa (Universidad del País Vasco UPV/EHU), 2016-01)
[EN] The aim of this paper is to determine to what extent globalization pressures are changing interlocking directorate networks modeled on continental capitalism into Anglo-Saxon models. For this purpose we analyse the ...
Dealing with the Effects of Sensor Displacement in Wearable Activity Recognition
(MDPI, 2014-06)
Most wearable activity recognition systems assume a predefined sensor deployment that remains unchanged during runtime. However, this assumption does not reflect real-life conditions. During the normal use of such systems, ...
