Mean Curvature Flow with a Neumann Boundary Condition in Flat Spaces [PDF]
, 2012 In this thesis I study mean curvature flow in both Euclidean and Minkowski space with a Neumann boundary condition. In Minkowski space I show that for a convex timelike cone boundary condition, with compatible spacelike initial data, mean curvature flow

Internationalization and ESG Controversies: Do Foreign Directors on Corporate Boards Matter?
Business Strategy and the Environment, EarlyView.ABSTRACT This study examines the relationship between internationalization and environmental, social, and governance (ESG) controversies, focusing on whether foreign directors on corporate boards influence this relationship. Drawing on resource dependence theory, we argue that internationalization increases ESG controversies due to the complexity of ...

Chemistry – A European Journal, EarlyView.We present a machine‐learning framework that predicts the electron localization function (ELF) of dense hydrogen directly from atomic geometry, bypassing explicit electronic‐structure calculations. Trained on ab initio data for fluid hydrogen across multiple pressures, the model achieves high accuracy and reveals pressure‐dependent nonlocal ...

Chemistry – A European Journal, EarlyView.The energy level diagrams for the ν(C═O) and the δ(N─H) vibrations, resulting of combining in‐phase and out‐of‐phase modes on the basis of their local symmetries, was built by applying the exciton coupling theory to a new class of chiral macrocycles, based on the 2,5‐diaminoterephthalate scaffold.

On the generalized eigenfunctions system of the Sturm–Liouville problem
Lietuvos Matematikos Rinkinys, 2008 In this paperwe investigate eigenfunctions and generalized eigenfunctions system of the Sturm– Liouville problem with classical boundary condition on the left boundary and nonlocal boundary conditions of four types on the right boundary.

Nitrogen‐Site Isomerism Unlocks Exciton Dissociation in Vinylene‐Linked COF‐Based Photocatalysts
EcoEnergy, EarlyView.Two regioisomeric vinylene‐linked covalent organic frameworks (COFs) constructed from diazine units with different nitrogen positions are developed for photocatalytic hydrogen evolution reaction (HER). Although structurally similar, the isomeric COFs exhibit distinct electron distribution and charge‐separation behaviors, leading to a more than twofold ...

On the Second Order of Accuracy Stable Implicit Difference Scheme for Elliptic-Parabolic Equations
Abstract and Applied Analysis, 2012 We are interested in studying a second order of accuracy implicit difference scheme for the solution of the elliptic-parabolic equation with the nonlocal boundary condition. Well-posedness of this difference scheme is established.
