Advanced Intelligent Systems, EarlyView.During lengthy minimally invasive surgeries, fatigue can cause surgeon tremor and poor endoscopic coordination. This study proposes a robot‐assisted endoscopic adjustment system. It employs a lightweight instrument detection model and a hierarchical multiconstraint controller for visual servoing.

Language‐Guided Robot Grasping Based on Basic Geometric Shape Fitting
Advanced Intelligent Systems, EarlyView.This article presents a language‐guided, model‐free grasping framework that integrates multimodal perception with primitive‐based geometric fitting. By explicitly modeling object geometry from RGB‐D data, the method enables semantically controllable grasp pose generation and achieves robust performance in both structured and cluttered real‐world ...

Angewandte Chemie International Edition, EarlyView.Catalysts with the isolated Co2+ species in the 6MR (Co2+─Z2) and 8MR ([Co(OH)]+─Z) windows of the SSZ‐13 zeolite were synthesized for non‐oxidative ethane dehydrogenation to ethene. The Co2+─Z2 species demonstrate an unexpectedly high rate of ethene formation in comparison with the ([Co(OH)]+─Z species.

Scanning of Vehicles for Nuclear Materials
, 2013 Might a nuclear-armed terrorist group or state use ordinary commerce to deliver a nuclear weapon by smuggling it in a cargo container or vehicle? This delivery method would be the only one available to a sub-state actor, and it might enable a state to ...

Efficient Dynamics: Reduced‐Order Modeling of the Time‐Dependent Schrödinger Equation
Advanced Physics Research, EarlyView.Reduced‐order modeling (ROM) approaches for the time‐dependent Schrödinger equation are investigated, highlighting their ability to simulate quantum dynamics efficiently. Proper Orthogonal Decomposition, Dynamic Mode Decomposition, and Reduced Basis Methods are compared across canonical systems and extended to higher dimensions.

Predicting ecology and hearing sensitivities in Parapontoporia—An extinct long‐snouted dolphin
The Anatomical Record, EarlyView.Abstract Analyses of the cetacean (whale and dolphin) inner ear provide glimpses into the ecology and evolution of extinct and extant groups. The paleoecology of the long‐snouted odontocete (toothed whale) group, Parapontoporia, is primarily marine with its depositional context also suggesting freshwater tolerance.
