Artificial Intelligence for Benign Esophageal Stricture Dilation: An Evidence‐Transferability Framework and Safety‐First Roadmap

open access: yesAI &Innovation, EarlyView.
ABSTRACT Background Endoscopic dilation is first‐line therapy for symptomatic benign esophageal strictures but remains operator‐dependent. Artificial intelligence (AI) could support assessment, risk stratification, and documentation; however, evidence from adjacent tasks is often mistaken for procedure‐specific validation.

Molecular Recognition by Halogen Bonding With Atomic Precision in a Covalent Organic Cage

open access: yesAngewandte Chemie, EarlyView.
A covalent organic cage embedding a single inward‐facing halogen‐bond (XB) donor enables recognition of DMMP, a Sarin surrogate, with atomic precision through halogen bonding, while both the hydrogen bonding donor encaged analogue and the XB donor open model ‐lacking cavity‐ show no affinity.

Discovery of the Cyclic Form of MRI pH‐Sensor Z‐OMPD Enables >5% 13C Hyperpolarization by SABRE

open access: yesAngewandte Chemie International Edition, EarlyView.
With “c‐OMPD”, we discovered a previously unknown 5‐membered lactol structure that arises from the homoaldol condensation of the central metabolite pyruvic acid. We demonstrate that the cyclization equilibrium is of crucial importance for OMPD's function as MRI‐based pH sensor and achieve for the first time 13C polarization levels (>5%) by SABRE in the

Radiative Hybrid Nanofluid Flow Over a Porous Riga Surface: A Fuzzy–ANN Modeling Approach

open access: yesAsia-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.
