Twisted Tin‐Chloride Perovskite Single‐Crystal Heterostructures

Angewandte Chemie, Volume 138, Issue 5, 28 January 2026.
Replacing lead with tin in a single‐crystal halide perovskite heterostructure drives a twist between the perovskite (gray) and intergrowth (blue) layers. The accompanying structural distortions and interfacial strain change the calculated orbital composition of the band edges and enable high in‐plane optical anisotropy in the Sn analog.

Inequalities of Green’s functions and positive solutions to nonlocal boundary value problems

Journal of Inequalities and Applications, 2020
In this paper, we discuss the positive solutions of beam equations with the nonlinearities including the slope and bending moment under nonlocal boundary conditions involving Stieltjes integrals.

Water‐Borne Erosion of Reinforced Polymer Composites: Application to Shallow Offshore Marine Environment

Polymer Composites, EarlyView.
Comparison of experimental and model‐predicted erosion rates for carbon fibre‐reinforced polymer (CFRP) and glass fibre‐reinforced polymer (GFRP) under low‐velocity (2 m/s) and at varying angles and sand concentrations (0.0, 0.05, 0.4 g/L). The results demonstrate good agreement between experimental data and model predictions across different erosive ...

Investigation of the Impact of XLPE Cable Ageing on Impedance Mismatch Characteristics and Unbalanced Behaviour in Hybrid Operation Systems

High Voltage, EarlyView.
ABSTRACT In the Hainan–Guangdong interconnection project, oil leakage in oil‐filled cables required replacing the faulty core with a single core from a three‐core cross‐linked polyethylene (XLPE) cable, leading to mixed operation of XLPE and oil‐filled cables.

On the Rate of Convergence of Kirk-Type Iterative Schemes

Journal of Applied Mathematics, 2012
The purpose of this paper is to introduce Kirk-type new iterative schemes called Kirk-SP and Kirk-CR schemes and to study the convergence of these iterative schemes by employing certain quasi-contractive operators. By taking an example, we will compare

Martingale Problem under Nonlinear Expectations [PDF]

, 2014
We formulate and solve the martingale problem in a nonlinear expectation space. Unlike the classical work of Stroock and Varadhan (1969) where the linear operator in the associated PDE is naturally defined from the corresponding diffusion process, the ...

Positive solutions for a system of $n$th-order nonlinear boundary value problems

Electronic Journal of Qualitative Theory of Differential Equations, 2011
In this paper, we investigate the existence, multiplicity and uniqueness of positive solutions for the following system of $n$th-order nonlinear boundary value problems \[\begin{cases} u^{(n)}(t)+f(t,u(t),v(t))=0 ...

Sublinear Equations and Schur’s Test for Integral Operators [PDF]

, 2018
We study weighted norm inequalities of $(p,r)$-type, $ \Vert \mathbf{G} (f \, d ) \Vert_{L^r( , d )} \le C \Vert f \Vert_{L^p( , )}, \quad \forall \, f \in L^p( ),$ for $0 < r < p$ and $p>1$, where $\mathbf{G}(f d )(x)=\int_ G(x, y) f(y) d (y)$ is an integral operator associated with a nonnegative kernel $G$ on $ \times $, and $

The dynamics of criminal collaboration: Multiplex ties in mafia networks

Criminology, EarlyView.
Abstract This study examines how social embeddedness and multiplex relationships shape criminal collaboration within organized crime networks. Drawing on data from three major investigations into the ‘Ndrangheta, we analyze how kinship, clan affiliation, leadership, and prior interactions influence participation in meetings and phone calls.

Pediatric Versus Adult Shear‐Induced Hemolysis—Are Age‐Related Blood Properties the Main Cause for Differences?

Artificial Organs, EarlyView.
Graphical summary of the experimental comparison of shear‐induced hemolysis in pediatric and adult blood using a Couette shearing device. Pediatric blood shows a trend toward lower increase in hemolysis at higher shear stress amplitudes, while no relevant differences are observed at low and intermediate stresses.
