Block locally optimal preconditioned eigenvalue Xolvers (BLOPEX) in Hypre and PETSc

open access: yes, 2007
We describe our software package Block Locally Optimal Preconditioned Eigenvalue Xolvers (BLOPEX) recently publicly released. BLOPEX is available as a stand-alone serial library, as an external package to PETSc (Portable, Extensible Toolkit for ...

Targeting the YAP‐BST2 Axis Overcomes Intrinsic Anti‐PD‐1 Resistance in Metastatic Gastric Cancer

open access: yesAdvanced Science, EarlyView.
Concurrent YAP hyperactivation and Tp53 loss in Atp4b‐expressed parietal cell lineage drives gastric cancer initiation, multi‐organ metastasis, and intrinsic resistance to anti‐PD‐1 therapy. BST2 emerges as a direct YAP‐TEAD transcriptional target that engages PIRA2 on myeloid cells to establish an immunosuppressive microenvironment.

Exceptional Antimodes in Multi‐Drive Cavity Magnonics

open access: yesAdvanced Electronic Materials, EarlyView.
Driven‐dissipative cavity‐magnonics provides a flexible platform for engineering non‐Hermitian physics such as exceptional points. Here, using a four‐port, three‐mode system with controllable microwave interference, antimodes and coherent perfect extinction (CPE) are realized, enabling active tuning to antimode exceptional points.

An eigenvalue problem possessing a continuous family of eigenvalues plus an isolated eigenvalue

open access: yesCommunications on Pure and Applied Analysis, 2011
In this paper we analyze an eigenvalue problem, involving a homogeneous Neumann boundary condition, in a smooth bounded domain. We show that the problem possesses, on the one hand, a continuous family of eigenvalues and, on the other hand, exactly one more eigenvalue which is isolated in the set of eigenvalues of the problem.

Balancing Carrier Cooling in InN/GaN Quantum Wells via Point Defect Engineering

open access: yesAdvanced Electronic Materials, EarlyView.
Nitrogen vacancies in the InN/GaN interface regulate carrier relaxation in polar quantum wells by reconstructing the conduction‐band decay pathway and enhancing nonadiabatic coupling. No deep midgap state is introduced in the neutral single‐vacancy model, enabling faster hot‐electron cooling, improved electron‐hole balance, reduced electron overflow ...

A generalization of the Landesman-Lazer condition

open access: yesElectronic Journal of Differential Equations, 2001
In this paper we prove the existence of solutions to the semi-linear problem $$ displaylines{ u''(x)+m^2 u(x)+g(x,u(x))=f(x)cr u(0)=u(pi)=0 }$$ at resonance.

Keeping Pace or Falling Behind? The Depth of Latin American Trade Agreements

open access: yesApplied Economic Perspectives and Policy, EarlyView.
ABSTRACT This article examines whether Latin American countries are keeping pace with global trends in trade agreement depth or falling behind. Using 681 agreements (1970–2019), we develop the Depth Index of Trade Agreements (DITA) to weight provisions endogenously through factor analysis based on co‐occurrence patterns.

Continuous spectrum of a fourth order nonhomogeneous elliptic equation with variable exponent

open access: yesElectronic Journal of Differential Equations, 2011
In this article, we consider the nonlinear eigenvalue problem $$displaylines{ Delta(|Delta u|^{p(x)-2}Delta u )=lambda |u|^{q(x)-2}uquad hbox{in }Omega, cr u=Delta u = 0quad hbox{on }partialOmega, }$$ where $Omega$ is a bounded domain in $mathbb{R}^

Enhancing Sustainability Label Effectiveness Through Logo Design Modification: An Analysis of the EU Green Leaf Logo

open access: yesAgribusiness, EarlyView.
ABSTRACT Sustainability labels can help support consumers select more socially and environmentally friendly options, thereby enhancing returns for conscientious producers and promoting the transition to a more sustainable food system. However, consumer confusion regarding labels' meaning undermines their effectiveness.
