High-Performance Asymmetric Optical Transmission Based on a Dielectric–Metal Metasurface

open access: yesNanomaterials, 2021
Asymmetric optical transmission plays a key role in many optical systems. In this work, we propose and numerically demonstrate a dielectric–metal metasurface that can achieve high-performance asymmetric transmission for linearly polarized light in the ...

Transmissibility of Mycoplasma Dispar under Experimental Conditions [PDF]

open access: yesActa Veterinaria Scandinavica, 1987
Twenty three 1- to 18-week old Ayrshire calves were exposed to infection by Mycoplasma dispar, 1 or 2 at a time, in a series of consecutive experiments. Exposure took place either at direct contact, i. e. with the possibility of physical contact between susceptible and infected calves (type I), or through separation of susceptibles from the nearest ...

Effect of photoperiod and host distribution on the horizontal transmission of Isaria fumosorosea (Hypocreales: Cordycipitaceae) in greenhouse whitefly assessed using a novel model bioassay [PDF]

open access: yes, 2010
A model bioassay was used to evaluate the epizootic potential and determine the horizontal transmission efficiency of Isaria fumosorosea Trinidadian strains against Trialeurodes vaporariorum pharate adults under optimum conditions (25±0.5°C, ~100% RH ...

Existence and uniqueness for a two-point interface boundary value problem

open access: yesElectronic Journal of Differential Equations, 2013
We obtain sufficient conditions, easily verifiable, for the existence and uniqueness of piecewise smooth solutions of a linear two-point boundary-value problem with general interface conditions.

Environmental Determinants of Malaria Transmission Around the Koka Reservoir in Ethiopia

open access: yesGeoHealth, 2018
New dam construction is known to exacerbate malaria transmission in Africa as the vectors of malaria—Anopheles mosquitoes—use bodies of water as breeding sites. Precise environmental mechanisms of how reservoirs exacerbate malaria transmission are yet to

A regularized trace formula for a discontinuous Sturm-Liouville operator with delayed argument

open access: yesElectronic Journal of Differential Equations, 2017
In this study, we obtain a formula for the regularized sums of eigenvalues for a Sturm-Liouville problem with delayed argument at two points of discontinuity.

Solvability and coerciveness of multi-point Sturm–Liouville problems with abstract linear functionals

open access: yesBoundary Value Problems, 2019
In this paper, we consider a Sturm–Liouville problem with finite discontinuous points inside an interval and with abstract linear functionals in the boundary and transmission conditions.

NUMERICAL METHODS FOR DISCONTINUOUS STURM-LIOUVILLE PROBLEMS

open access: yesJournal of New Theory, 2015
− This study is devoted to determining the eigenvalues and eigenfunctions of a discontinuous Sturm-Liouville Problem. By modifying the finite difference method, we have developed anumerical approximation to the eigenvalues and ...

Global Existence of Solutions to a Free Boundary Problem for Viscous Incompressible Magnetohydrodynamics for Small Data

open access: yesMathematics
The motion of viscous incompressible magnetohydrodynamics (MHD) is considered in a domain that is bounded by a free surface. The motion interacts through the free surface with an electromagnetic field located in a domain exterior to the free surface and ...

The Parseval identity for q-Sturm–Liouville problems with transmission conditions

open access: yesAdvances in Difference Equations, 2021
In the present study, we investigate the existence of spectral functions and obtain the Parseval identity and expansion formula in eigenfunctions for the singular q-Sturm–Liouville problem with transmission conditions.
