Nonexistence of invariant measures [PDF]
Proceedings of the American Mathematical Society, 1983 Let G G be a group acting on a set X X . Suppose that for some positive integer r r , G G contains a free group F F of rank > r > r and the intersection of any stabilizer with F F has rank ⩽

Does Participating in Agricultural Global Value Chains Promote Agricultural Growth?
Agribusiness, EarlyView.ABSTRACT This study examines the relationship between GVC participation and agricultural value‐added growth in 43 countries over the period 1995–2022. In contrast to prior literature, we disaggregate the agricultural sector into four sub‐sectors namely crop cultivation, animal production, forestry and fishing.

Electronic Journal of Qualitative Theory of Differential Equations, 2015 We obtain results on nonexistence of nontrivial nonnegative solutions for some elliptic and parabolic inequalities with functional parameters involving the $p(x)$-Laplacian operator. The proof is based on the test function method.

Remarks on two fourth order elliptic problems in whole space
, 2014 We are interested in entire solutions for the semilinear biharmonic equation $\Delta^{2}u=f(u)$ in $\R^N$, where $f(u)=e^{u}$ or $-u^{-p}\ (p>0)$. For the exponential case, we prove that any classical entire solution verifies $-\Delta u>0$ without any ...

The Insistence of Blackness and the Persistence of Antiblackness in Ireland
Australian Journal of Social Issues, EarlyView.ABSTRACT This paper positions Ireland as a critical site for examining the insistence of blackness and an antiblackness created and sustained through Irish ethnonationalist imaginaries and exclusionary processes. Drawing on connected sociologies and Irish Black Studies, this enquiry argues that antiblackness in Ireland operates as a generational force,

Nonexistence of an integral of the 6th degree in momenta for the Zipoy-Voorhees metric
, 2011 We prove nonexistence of a nontrivial integral that is polynomial in momenta of degree less than 7 for the Zipoy-Voorhees spacetime with the parameter $\delta=2$Comment: 7 pages, no ...

The Progress of Orbitronics: The Enhancement of Orbital Torque Efficiency
Advanced Physics Research, EarlyView.Orbit‐torque (OT) devices attract significant attention for their low‐power consumption and high stability in applications. This review systematically outlines strategies for enhancing OT efficiency. We categorize approaches into boosting orbital currents/torques and improving the orbital‐to‐spin conversion coefficient.

Animal Research and One Health, EarlyView.Antimicrobial resistance (AMR) is an escalating global threat driven by antimicrobial use in aquaculture and livestock. Resistant pathogens and genes can spread across humans, animals, and the environment through interconnected ecosystems. Using a One Health approach, this review emphasizes antimicrobial stewardship, regulatory strengthening, enhanced ...

Nonexistence of stable solutions to quasilinear elliptic equations on Riemannian manifolds
, 2016 We prove nonexistence of nontrivial, possibly sign changing, stable solutions to a class of quasilinear elliptic equations with a potential on Riemannian manifolds, under suitable weighted volume growth conditions on geodesic ...

Business Strategy and the Environment, EarlyView.ABSTRACT Considering the growing attention to sustainability and the increasing regulatory pressure in the European landscape, this study evaluates whether greenhouse gas emissions affect firms' cost of debt. A panel regression was conducted from 2021 to 2024 on two samples of European firms.
