Facility Location in the Sublinear Geometric Model [PDF]
, 2023 In the sublinear geometric model, we are provided with an oracle access to a point set P of n points in a bounded discrete space [Δ]², where Δ = n^O(1) is a polynomially bounded number in n. That is, we do not have direct access to the points, but we can

Flexoelectric Suppression of Interfacial Carrier Loss in BaTiO3 Thin‐Film Bulk Photovoltaic Systems
Advanced Science, EarlyView.In single‐crystalline BaTiO3 thin films, flexoelectric strain gradients strongly enhance photocurrent by suppressing interfacial carrier loss. Loading experiments reveal a ∼35‐fold photocurrent increase with applied force. Self‐consistent electrostatic modeling shows that strain gradients reshape the interfacial potential landscape, strengthen local ...

A note on sublinear separators and expansion [PDF]
European Journal of Combinatorics, 2021 For a hereditary class C of graphs, let s_C(n) be the minimum function such that each n-vertex graph in C has a balanced separator of order at most s_C(n), and let nabla_C(r) be the minimum function bounding the expansion of C, in the sense of bounded expansion theory of Nešetřil and Ossona de Mendez.

Positive and monotone solutions of an m-point boundary-value problem
Electronic Journal of Differential Equations, 2002 We study the second-order ordinary differential equation $$ y''(t)=-f(t,y(t),y'(t)),quad 0leq tleq 1, $$ subject to the multi-point boundary conditions $$ alpha y(0)pm eta y'(0)=0,quad y(1)=sum_{i=1}^{m-2}alpha_iy(xi_i),.

Advanced Electronic Materials, EarlyView.This work presents a dual‐band photodetector based on the large‐scale, precise synthesis of Cs2AgBiBr6 single crystals. A rapid and efficient synthesis method is demonstrated, yielding high‐quality Cs2AgBiBr6 crystals with an average size of 2 × 2 × 1.5 mm3 and a production yield of 12.66%.

Quasilinear problems with two parameters including superlinear and gradient terms
Electronic Journal of Differential Equations, 2014 In this article, we establish conditions for the existence of solutions for a quasilinear elliptic two-parameter problem with dependence on the gradient term in smooth bounded domains or in the whole space R^N.

A Strong Law of Large Numbers for Weighted Sums of i.i.d. Random Variables under Capacities
Journal of Applied Mathematics, 2014 With the notion of independent identically distributed (i.i.d.) random variables under sublinear expectations initiated by Peng, a strong law of large numbers for weighted sums of i.i.d. random variables under capacities induced by sublinear expectations

Testing hereditary properties of nonexpanding bounded-degree graphs [PDF]
, 2007 We study graph properties that are testable for bounded-degree graphs in time independent of the input size. Our goal is to distinguish between graphs having a predetermined graph property and graphs that are far from every graph having that property. It

Advanced Energy Materials, EarlyView.Transient electron spin resonance distinguishes interfacial charge‐transfer states from separated charges, revealing competing charge separation pathways in organic photovoltaic blends. The relative contributions of fast charge separation and a pathway mediated by spin‐polarized charge‐transfer states vary across different blends, with high‐efficiency ...

On positive solutions for classes of quasilinear singular problems
Electronic Journal of Qualitative Theory of Differential EquationsWe study classes of quasilinear singular problems, involving the $p$-Laplacian operator and a potential, with homogeneous Dirichlet boundary condition. First, we prove the existence and regularity of positive solutions to a purely singular problem. Then,
