On a Nonlinear Hyperbolic–Elliptic System Modeling Chemotaxis

Mathematics
In this paper, we study a hyperbolic–elliptic system with L1-initial data, which arises as a mathematical model for chemotaxis. In particular, after introducing the notion of entropy solutions in this setting, we prove results concerning the existence of

US Consumer Appetite for Climate Claims on Beef Products: Does Country‐of‐Origin Matter?

Australian Journal of Agricultural and Resource Economics, EarlyView.
ABSTRACT Beef cattle producers have been receiving pressure to reduce methane emissions from production. Beef products with varying climate claims have recently been introduced to the retail sector, stemming from various countries‐of‐origin. Using data from a US consumer survey, we find a subset of US consumers is willing to pay a premium for Lower ...

Simulating the Brio model via generalized Rusanov scheme in magnetohydrodynamics

Results in Physics
The Brio system is a nonlinear system of conservation laws that is used to analyze plasmas. The current research presents numerical solutions to this model exposed to initial conditions using the generalized Rusanov (G. Rusanov) scheme.

GOVERNING THE CLOUD: Infrastructural Statecraft and the Political Ecology of Digital Expansion in Oregon

International Journal of Urban and Regional Research, EarlyView.
Abstract Oregon's wave of data center and semiconductor projects shows how cloud capitalism reorganizes resource systems and territorial governance. Examining Amazon, Google, and Intel, the article traces how fiscal incentives, utility programs, and land‐use instruments are recalibrated to secure hyperscale loads.

Heterogeneous Spillover Effects: How FDI in Resources Extraction, Manufacturing, and Services Affect Sectoral Carbon Emissions in the MENA Region

Natural Resources Forum, EarlyView.
ABSTRACT The MENA region faces a critical challenge: balancing economic growth spurred by foreign direct investment (FDI) with environmental sustainability. While FDI can bring technological advancements and capital, concerns exist about its potential to exacerbate environmental degradation, particularly carbon emissions.

Landowners' Willingness to Participate in Temporary and Permanent Agri‐Environmental Schemes

Journal of Agricultural Economics, EarlyView.
ABSTRACT Within the EU and beyond, voluntary agri‐environmental and climate schemes (AES) are used to curtail externalities from agricultural production including nitrate leaching, biodiversity degradation and greenhouse gas emissions. This paper investigates and compares Danish landowners' preferences for temporary and permanent AES using a choice ...

US Farm Bill in 2025: Ad Hoc Assistance becomes an Expanded Multi‐Year Safety Net Loi agricole américaine de 2025 : l'aide ponctuelle devient un filet de sécurité pluriannuel élargi US Farm Bill in 2025: Ad‐hoc‐Beihilfen werden zu einem erweiterten mehrjährigen Sicherheitsnetz

EuroChoices, EarlyView.
Summary The 2025 US farm bill converts ad hoc farm assistance since 2018 into a projected US$ 62 billion farm safety net expansion within multi‐year legislation. Usually stand‐alone with strong bipartisan support, the 2025 edition is largely provisions in a far‐reaching, partisan budget law. The farm safety net is expanded by cutting food assistance to

Cenozoic Tectonics Ignite Mitochondrial Codon Innovations Propelling Canid Body Size Evolution and Transcontinental Radiations

Integrative Zoology, EarlyView.
We decode mitochondrial genomes across all extant canids, revealing lineage‐specific codon optimization driven by altitude, predation, and body size. A tripartite framework integrates geological events, metabolic constraints, and adaptive radiation to explain carnivore evolution.
