Do's and Don'ts When Visiting Circularly Polarized Luminescence
Advanced Optical Materials, EarlyView.This perspective presents our insights into the principles, challenges, and opportunities of circularly polarized luminescence (CPL). Highlighting key concepts such as the dissymmetry factor (glum) and molecular design strategies, we discuss advances in CPL efficiency, emerging NIR emitters, solid‐state applications, and the growing role of theory and ...

On Conformal Vector Fields Parallel to The Observer Field
, 2008 We review a theorem by Hasse and Perlick establishing a result characterizing parallax-free cosmological models via three equivalent properties -- namely the existence of a redshift potential, the existence of a conformal vector field parallel to the observer field, and the vanishing of the shear of the observer field together with some integrability ...

Conformal Mappings of Mixed Generalized Quasi-Einstein Manifolds Admitting Special Vector Fields
Extracta Mathematicae, 2017 It is known that Einstein manifolds form a natural subclass of the class of quasi-Einstein manifolds and plays an important role in geometry as well as in general theory of relativity.

2-conformal and conformal vector fields on Riemannian manifolds
FilomatIn this paper, we study 2-conformal vector fields on Riemannian manifolds. Some relations between 2-conformal vector fields, conformal vector fields, Killing and 2-Killing vector fields have been obtained. Also, relation between monotone vector fields and 2-conformal vector fields is investigated.

Foliations Transverse to a Closed Conformal Vector Field
Results in MathematicsIn this article, we study the geometric properties of codimension one foliations on Riemannian manifolds equipped with vector fields that are closed and conformal. Apart from its singularities, these vector fields define codimension one foliations with nice geometric features, which we call Montiel Foliations.

TreeSpider: In‐Canopy Exploration With Tether‐Based Aerial Modular Arms
Advanced Robotics Research, EarlyView.A tethered drone with perching arms and a 360° ring enables unprecedented maneuverability within dense forest canopies. By dynamically adjusting tether length and decoupling pitch from the frame, it navigates between branches, senses multiple trees, and interacts physically with foliage.

Advanced Robotics Research, EarlyView.Automated poultry processing lines still rely on humans to lift slippery, easily bruised carcasses onto a shackle conveyor. Deformability, anatomical variance, and hygiene rules make conventional suction and scripted motions unreliable. We present ChicGrasp, an end‐to‐end hardware‐software co‐designed imitation learning framework, to offer a ...
