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.

Scalable Task Planning via Large Language Models and Structured World Representations
Advanced Robotics Research, EarlyView.This work efficiently combines graph‐based world representations with the commonsense knowledge in Large Language Models to enhance planning techniques for the large‐scale environments that modern robots will need to face. Planning methods often struggle with computational intractability when solving task‐level problems in large‐scale environments ...

Normalisers of primitive permutation groups
, 2020 We present a new approach to computing the normaliser of a primitive group G in an arbitrary subgroup H of S_n. Our method runs in quasipolynomial time O(2^{\log^3 n}), whereas the previous best known algorithm was simply exponential. The main tools used

Overgroups of primitive groups, II
Journal of Algebra, 2009 Assume that \(\Omega\) is a set of finite order \(n\), \(G\in\{\text{Sym}(\Omega),\text{Alt}(\Omega)\}\), and \(H\) is a subgroup of \(G\) acting primitively on \(\Omega\). In this paper it is continued the study of the set \(\mathcal O_G(H)\) of overgroups of \(H\) in \(G\) [for part I cf. J. Aust. Math. Soc. 87, No.

Non-noetherian groups and primitivity of their group algebras
Journal of Algebra, 2017 We prove that the group algebra $KG$ of a group $G$ over a field $K$ is primitive, provided that $G$ has a free subgroup with the same cardinality as $G$, and that $G$ satisfies the following condition $(\ast)$: for each subset $M$ of $G$ consisting of a finite number of elements not equal to $1$, and for any positive integer $m$, there exist distinct $

Learning Highly Dynamic Skills Transition for Quadruped Jumping Through Constrained Space
Advanced Robotics Research, EarlyView.A quadruped robot masters dynamic jumps through constrained spaces with animal‐inspired moves and intelligent vision control. This hierarchical learning approach combines imitation of biological agility with real‐time trajectory planning. Although legged animals are capable of performing explosive motions while traversing confined spaces, replicating ...

On primitive ideals in graded rings [PDF]
, 2008 Let R = circle plus(infinity)(i=1) Ri be a graded nil ring. It is shown,that primitive ideals in R are homogeneous. Let A = circle plus(infinity)(i=1) Ai be a graded non-PI just-infinite dimensional algebra and let I be a prime ideal in A.
