One-dimensional potential for image-potential states on graphene
(IOP Publishing, 2014-02-05)
In the framework of dielectric theory, the static non-local self-energy of an electron near an ultra-thin polarizable layer has been calculated and applied to study binding energies of image-potential states near free-standing ...
Higher order vortex gyrotropic modes in circular ferromagnetic nanodots
(Nature Publishing Group, 2014-04-25)
Magnetic vortex that consists of an in-plane curling magnetization configuration and a needle-like core region with out-of-plane magnetization is known to be the ground state of geometrically confined submicron soft magnetic ...
Microwave absorption properties of permalloy nanodots in the vortex and quasi-uniform magnetization states
(IOP Publishing, 2014-06-19)
When the in-plane bias magnetic field acting on a flat circular magnetic dot is smaller than the saturation field, there are two stable competing magnetization configurations of the dot: the vortex and the quasi-uniform ...
Pata contractions and coupled type fixed points
(Springer International Publishing, 2014-06-02)
A new coupled fixed point theorem related to the Pata contraction for mappings having the mixed monotone property in partially ordered complete metric spaces is established. It is shown that the coupled fixed point can be ...
Do Nutritional Supplements Have a Role in Age Macular Degeneration Prevention?
(Hindawi Publishing, 2014)
Purpose. To review the proposed pathogenic mechanisms of age macular degeneration (AMD), as well as the role of antioxidants (AOX) and omega-3 fatty acids (omega-3) supplements in AMD prevention. Materials and Methods. ...
Linear Chromatic Adaptation Transform Based on Delaunay Triangulation
(Hindawi Publishing, 2014)
Computer vision algorithms that use color information require color constant images to operate correctly. Color constancy of the images is usually achieved in two steps: first the illuminant is detected and then image is ...
An enactive and dynamical systems theory account of dyadic relationships
(Frontiers Research Foundation, 2014-05-30)
Many social relationships are a locus of struggle and suffering, either at the individual or interactional level. In this paper we explore why this is the case and suggest a modeling approach for dyadic interactions and ...
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 ...
