Experimental and Numerical Investigations of Backscatter Patterns of the Blocks of Masking Digital Two-Bit Meta-covers

open access: yesИзвестия высших учебных заведений России: Радиоэлектроника, 2021
Introduction. The scattering patterns of non-absorbing coded checkerboard-like meta-coatings (MCs) applied for reducing the radar cross section (RCS) of metal surfaces inevitably contain side diffraction lobes.

Etiology-Specific Remodeling in Ventricular Tissue of Heart Failure Patients and Its Implications for Computational Modeling of Electrical Conduction

open access: yesFrontiers in Physiology, 2021
With an estimated 64.3 million cases worldwide, heart failure (HF) imposes an enormous burden on healthcare systems. Sudden death from arrhythmia is the major cause of mortality in HF patients.

Magnetic cylindrical colloids at liquid interfaces exhibit non-volatile switching of their orientation in an external field [PDF]

open access: yes, 2016
We study the orientation of magnetic cylindrical particles adsorbed at a liquid interface in an external field using analytical theory and high resolution finite element simulations.

Two dimensional dipolar scattering with a tilt

open access: yes, 2011
We study two body dipolar scattering in two dimensions with a tilted polarization axis. This tilt reintroduces the anisotropic interaction in a controllable manner.

Comparison of Modelled and Measured Tilted Solar Irradiance for Photovoltaic Applications

open access: yesEnergies, 2017
This work assesses the performance of five transposition models that estimate the global and diffuse solar irradiance on tilted planes based on the global horizontal irradiance.

On the relationship between aspect sensitivity, wave activity, andmultiple scattering centers of mesosphere summer echoes: a case study using coherent radar imaging [PDF]

open access: yesAnnales Geophysicae, 2004
A mesosphere-summer-echo layer, observed by the OSWIN VHF radar (54.1°N, 11.8°E) with vertical and 7° oblique radar beams, was examined using the method of coherent radar imaging (CRI).

Complex evolution of the electronic structure from polycrystalline to monocrystalline graphene: generation of a new Dirac point

open access: yes, 2009
First principles calculations, employed to address the properties of polycrystalline graphene, indicate that the electronic structure of tilt grain boundaries in this system displays a rather complex evolution towards graphene bulk, as the tilt angle ...

Momentum Dependence of the Single-Particle Self-Energy and Fluctuation Spectrum of Slightly Underdoped Bi_2 Sr_2 CaCu_2 O_{8+\delta} from High Resolution Laser ARPES [PDF]

open access: yes, 2010
We deduce the normal state angle-resolved single-particle self-energy $\Sigma(\theta, \omega)$ and the Eliashberg function (i.e., the product of the fluctuation spectrum and its coupling to fermions) $\alpha^2 F(\theta,\omega)$ for the high temperature ...

Dielectric and Electro-Optic Effects in a Nematic Liquid Crystal Doped with h-BN Flakes

open access: yesCrystals, 2020
A small quantity of hexagonal boron nitride (h-BN) flakes is doped into a nematic liquid crystal (LC). The epitaxial interaction between the LC molecules and the h-BN flakes rising from the π−π electron stacking between the LC’s ...
