American Journal of Agricultural Economics, EarlyView.Abstract This paper derives a firm‐level threshold, the Herfindahl Neutral Point, from the standard concentration index used in merger review. At this threshold, a marginal expansion leaves the index unchanged. Firms below the threshold reduce concentration when they expand; firms above it increase concentration.

Angewandte Chemie, EarlyView.A mechano‐triggered polythiourethane (PTU) synthesis mediated by a two‐electron pathway. The polymerization proceeds efficiently (<1 h) under focused ultrasound, achieving >90% conversion without any conventional base catalyst. The approach demonstrates broad compatibility with various thiol/isocyanate monomer combinations, highlighting its synthetic ...

Risk management externalities in agrifood supply chains
American Journal of Agricultural Economics, EarlyView.Abstract Firms may under‐ or over‐invest in risk management from the social planner's perspective, resulting in a negative externality on other economic agents in the supply chain. The externality of risk management is particularly relevant for agrifood supply chains, which frequently experience disruptions and play a primary role in preventing major ...

Advanced NanoBiomed Research, EarlyView.This study presents a label‐free spectroscopic platform to evaluate membrane protein conformation on patient‐derived glioblastoma cell membrane‐coated magnetic nanovectors. This work demonstrates that preserving membrane protein integrity during nanoparticle fabrication enhances homotypic tumor targeting and reduces hard protein corona formation ...

Radiative Hybrid Nanofluid Flow Over a Porous Riga Surface: A Fuzzy–ANN Modeling Approach
Asia-Pacific Journal of Chemical Engineering, EarlyView.ABSTRACT This study proposes a fuzzy–ANN model to investigate the nonlinear thermal transport in a tangent hyperbolic (Tanh) hybrid nanofluid flow past a porous Riga surface, considering the effects of Rosseland diffusion, chemical reactions, and internal volumetric heating.

Scale‐space image analysis for mapping spotted knapweed in grassland ecosystems
Applications in Plant Sciences, EarlyView.Abstract Premise This study investigates the value of scale‐space representations of spatial features for the identification and mapping of invasive plants using high‐resolution multispectral imagery. Scale‐space representations combine the two‐dimensional spatial domain with a third dimension representing spatial scale, such that features can be ...
