Understanding the Impact of Cu-In-Ga-S Nanoparticles Compactness on Holes Transfer of Perovskite Solar Cells

open access: yesNanomaterials, 2019
Although a compact holes-transport-layer (HTL) film has always been deemed mandatory for perovskite solar cells (PSCs), the impact their compactness on the device performance has rarely been studied in detail. In this work, based on a device structure of

A compact group which is not Valdivia compact [PDF]

open access: yesProceedings of the American Mathematical Society, 2005
A compact space $K$ is {\em Valdivia compact} if it can be embedded in a Tikhonov cube $I^A$ in such a way that the intersection $K\cap $ is dense in $K$, where $ $ is the sigma-product (= the set of points with countably many non-zero coordinates).

The Variable Effect of Polyploidization on the Phenotype in Escallonia

open access: yesFrontiers in Plant Science, 2018
To induce new variation within the Escallonia genus, chromosome doubling was performed in E. rubra, E. rosea, and E. illinita, three important species within this genus of mainly evergreen woody ornamental species.

Compactness and blow up results for doubly perturbed Yamabe problems on manifolds with non umbilic boundary

open access: yesElectronic Research Archive, 2022
We study the stability of compactness of solutions for the Yamabe boundary problem on a compact Riemannian manifold with non umbilic boundary. We prove that the set of solutions of Yamabe boundary problem is a compact set when perturbing the mean ...

Analysis of the Mechanism of Ground Fissures in the Nairobi–Malaba Railway Rift Valley Area in Kenya

open access: yesFrontiers in Earth Science, 2022
During the rainy season from March to May 2018, four ground fissures were generated in the rift valley area along the first phase of the Nairobi–Malaba Railway in Kenya, among which the ground fissures B3 highway, DK76, and DK77 were larger in scale ...

Compactness and collective compactness in spaces of compact operators

open access: yesJournal of Mathematical Analysis and Applications, 1981
AbstractThis is a study of compactness in (a) spaces Kb(X, Y) of compact linear operators, (b) injective tensor products X \̃boϵ Y, and (c) spaces Lc(X, Y) of continuous linear operators, and its various relationships with equicontinuity and collective compactness.

Blow-up solutions with minimal mass for nonlinear Schrödinger equation with variable potential

open access: yesAdvances in Nonlinear Analysis, 2021
This paper studies the mass-critical variable coefficient nonlinear Schrödinger equation. We first get the existence of the ground state by solving a minimization problem.

A topological proof of Sklar’s theorem in arbitrary dimensions

open access: yesDependence Modeling, 2022
Copulas are appealing tools in multivariate probability theory and statistics. Nevertheless, the transfer of this concept to infinite dimensions entails some nontrivial topological and functional analytic issues, making a deeper theoretical understanding
