Advanced Optical Materials, EarlyView.Nearly hyperuniform disordered photonic slabs guide light along prescribed freeform pathways without relying on lattice symmetry. A pathway‐first design embeds curved channels within a photonic bandgap hyperuniform network, maintaining high transmission through freeform bends.

Advanced Optical Materials, EarlyView.This work presents an electrically controllable approach to spin–valley polarization in monolayer WS2 by integrating it with a dual‐mode liquid crystal laser. Applying an external field triggers phase transitions that switch the laser emission between helicity‐defined band‐edge lasing and unpolarized random lasing.

On φ-pseudo symmetric LP-Sasakian manifolds with respect to quarter-symmetric non-metric connections [PDF]
, 2016 The object of the present paper is to study φ-pseudo symmetric and φ-pseudo Ricci symmetric LP-Sasakian manifolds with respect to Levi–Civita connections and quarter-symmetric non-metric connections. We obtain a necessary and sufficient condition for a φ-

Advanced Optical Materials, EarlyView.A maskless, SLM‐driven approach enables the deterministic inscription of arbitrary topographical features in azopolymer films by mapping complex vectorial light fields onto local viscoplastic stress. This platform allows for the rapid generation and dynamic erasure of high‐aspect‐ratio micro‐spikes, offering a versatile tool for reconfigurable flat ...

Echinoderm‐Inspired Autonomy for Soft‐Legged Robots
Advanced Robotics Research, EarlyView.Inspired by echinoderms, a modular soft robot achieves autonomous phototaxis without a central controller or explicit communication. Each limb independently adapts its actuation timing through local sensing and short‐term memory. Coordination emerges purely from physical interactions, demonstrating resilience to changes in morphology, environment, and ...

Continuum Mechanics Modeling of Flexible Spring Joints in Surgical Robots
Advanced Robotics Research, EarlyView.A new mechanical model of a tendon‐actuated helical extension spring joint in surgical robots is built using Cosserat rod theory. The model can implicitly handle the unknown contacts between adjacent coils and numerically predict spring shapes from straight to significantly bent under actuation forces.

Semi-Symmetry Properties of S-Manifolds Admitting a Quarter-Symmetric Metric Connection
, 2020 In this study S-manifolds admitting a quarter-symmetric metric connection naturally related with the S-structure are considered and some general results concerning the curvature of such a connection are given. In addition, we prove that an S-manifold has
