Import Wheat Tenders and the Effects of the Russian Invasion
ABSTRACT Risk and volatility for many commodities escalated sharply following the Russian invasion of Ukraine, creating numerous uncertainties for trading firms and importers. The purpose of this study is to analyze the bidding behavior in Egyptian wheat import tenders in the pre‐ and post‐invasion periods.

A Homogeneously Catalyzed Paired Electrolytic Cell for Hydrogen Peroxide Production
Cu(tmpa) and Sn‐TMPyP are compatible and efficient catalysts for 2e−‐ORR and 2e−‐WOR, respectively, which have been employed to assemble an efficient paired electrochemical cell for H2O2 production. The presence of a carbonate buffer is essential to achieve a high activity in the anode compartment, while control over mass transport is essential for a ...

AI in chemical engineering: From promise to practice
Abstract Artificial intelligence (AI) in chemical engineering has moved from promise to practice: physics‐aware (gray‐box) models are gaining traction, reinforcement learning complements model predictive control (MPC), and generative AI powers documentation, digitization, and safety workflows.

Aryl and Alkyl Radiotrifluoromethylation via Metallaphotoredox‐Mediated Radical Cross‐Coupling
The metallaphotoredox‐mediated radiotrifluoromethylation of arenes and alkanes is described. The operationally simple protocols make use of substrates bearing thianthrenium salts (TT) or N‐hydroxyphthalimide (NHPI) esters and CF218FI. The reaction proceeds through a Ru‐mediated radical formation followed by a Cu‐mediated radical cross‐coupling step and

Domain‐Aware Implicit Network for Arbitrary‐Scale Remote Sensing Image Super‐Resolution
Although existing arbitrary‐scale image super‐resolution methods are flexible to reconstruct images with arbitrary scales, the characteristic of training distribution is neglected that there exists domain shift between samples of various scales. In this work, a Domain‐Aware Implicit Network (DAIN) is proposed to handle it from the perspective of domain

Automatic Determination of Quasicrystalline Patterns from Microscopy Images
This work introduces a user‐friendly machine learning tool to automatically extract and visualize quasicrystalline tiling patterns from atomically resolved microscopy images. It uses feature clustering, nearest‐neighbor analysis, and support vector machines. The method is broadly applicable to various quasicrystalline systems and is released as part of

Facilitating Genetic Testing for Perinatal Demise: Development of a Multidisciplinary Workflow
ABSTRACT Genetic contributors to perinatal demise are common but frequently undiagnosed due to clinical and logistical barriers. We aimed to improve access to genetic for intrauterine fetal demise (IUFD), stillbirth, and early neonatal death by developing a multidisciplinary workflow.
