On Compressible Fluid Flows of Forchheimer‐Type in Rotating Heterogeneous Porous Media
Mathematical Methods in the Applied Sciences, EarlyView.ABSTRACT We study the dynamics of compressible fluids in rotating heterogeneous porous media. The fluid flow is of Forchheimer‐type and is subject to a mixed mass and volumetric flux boundary condition. The governing equations are reduced to a nonlinear partial differential equation for the pseudo‐pressure.

Magnetic Resonance in Medicine, EarlyView.ABSTRACT Purpose To improve the accuracy of diffusion‐weighted powder average signals for diffusion encoding with arbitrary b‐tensors. Methods We identify an intrinsic dihedral (D2$$ {D}_2 $$) symmetry of diffusion signals for arbitrary diffusion encoding, which defines their natural signal space (a quotient of 3D rotations).

International Journal for Numerical and Analytical Methods in Geomechanics, EarlyView.ABSTRACT This study proposes a novel geometrically regularized gradient‐damage model for simulating dynamic mixed‐mode fracture in orthotropic materials with tension–compression asymmetry. In this model, a thermodynamic framework is formulated by incorporating damage dissipation into internal energy evolution, from which the constitutive relation and ...

Information Design for Early‐Stage Dose‐Finding Trials
Naval Research Logistics (NRL), EarlyView.ABSTRACT To enhance enrollment rates in early‐stage dose‐finding clinical trials, we propose an information design approach, where the clinical investigator (CI) commits to an information releasing mechanism (IRM) based on the treatment's uncertain efficacy and toxicity to encourage patients to participate in the trial.

Naval Research Logistics (NRL), EarlyView.ABSTRACT This paper addresses two‐dimensional orthogonal packing within a confined space, integrating bin packing principles with facility layout concepts to address scenarios in which items must not only fit but also be arranged according to spatial priorities.

Interdiction Models and Heuristics for Graph Propagation
Networks, EarlyView.ABSTRACT Given a graph G=(V,E)$$ G=\left(V,E\right) $$ and a set S⊂V$$ S\subset V $$ of activated/infected nodes, we consider the problem of determining the set of c$$ c $$ nodes that minimizes the network propagation on the subgraph that results from the removal of those c$$ c $$ nodes. To measure network propagation, we assume that a node i$$ i $$ is

Otolaryngology–Head and Neck Surgery, EarlyView.Abstract Objective Chronic rhinosinusitis (CRS) affects all sociodemographic groups. While studies have explored social determinants of health (SDOH), sociodemographics, and health behaviors, their specific effects on CRS outcomes are unclear, making tailored care difficult.

A Framework for Understanding and Evaluating Localization: The Case of HelpAge International
Public Administration and Development, EarlyView.ABSTRACT Many transnational non‐governmental organizations (TNGOs) are reevaluating their organizational forms and norms as they pursue localization. Localization itself is a contested and multifaceted concept, however, complicating the design, implementation, and evaluation of localization efforts.

AI‐Ready Bureaucracies? Assessing Capacity‐Building Approaches in European National AI Strategies
Public Administration and Development, EarlyView.ABSTRACT The global expansion of Artificial Intelligence (AI) strategies is reshaping expectations about state capacity, yet the role of civil servants in this transition remains insufficiently theorized. This study examines how EU Member States address the civil service workforce in their national AI strategies, employing content and cluster analysis ...

People and Nature, EarlyView.Abstract Governments worldwide are committed to eliminating hunger and conserving biodiversity, reflected in United Nations Sustainable Development Goals 2 (Zero Hunger) and 15 (Life on Land). Expanding agricultural lands to meet growing food demands often threatens biodiversity, creating potential trade‐offs between these objectives. To understand the
