Normal automorphisms of relatively hyperbolic groups
, 2010 An automorphism of a group G is normal if it fixes every normal subgroup of G setwise. We give an algebraic description of normal automorphisms of relatively hyperbolic groups.

Advanced Engineering Materials, EarlyView.This study applies machine learning regression to predict chromium layer thickness in decorative trivalent chromium electroplating, using 441 experiments from laboratory‐scale (1L) and pilot‐scale (14L) setups. Tree‐based models, particularly CatBoost, outperformed linear regression by capturing nonlinear parameter interactions (R2$R^2$ up to 0.77 ...

KK-groups of twisted crossed products by groups acting on trees [PDF]
Pacific Journal of Mathematics, 1996 Using a description, in terms of twisted crossed products, of a similarity between the \(C^*\)-algebra \(M_n\) of \(n\times n\) complex entried matrices and the \(C^*\)-algebra \(C^*(G)\) for a discrete group, the author generalizes to the case of crossed products twisted by a circle-valued cocycle an exact sequence of Pimsner for \(KK\)-groups of ...

Advanced Functional Materials, EarlyView.Shellac, a centuries‐old natural resin, is reimagined as a green material for flexible electronics. When combined with silver nanowires, shellac films deliver transparency, conductivity, and stability against humidity. These results position shellac as a sustainable alternative to synthetic polymers for transparent conductors in next‐generation ...

Groups acting on trees with Tits' independence property (P)
, 2022 A 1970 article of J. Tits concerning groups acting on trees introduced an independence property $(\mathrm{P})$ as a condition to produce the first examples of nonlinear nondiscrete locally compact simple groups, answering a question of J. P. Serre.

Geometric interpretations for Fourier multipliers on groups acting on trees
, 2023 In this paper, we study Fourier multipliers on groups that admit actions on trees, using a geometric argument. In particular, we obtain the boundedness of the multipliers we construct on the non-commutative Lp-spaces (1 < p < ∞) associated with the

Machine Learning‐Assisted Inverse Design of Soft and Multifunctional Hybrid Liquid Metal Composites
Advanced Functional Materials, EarlyView.A machine learning framework is presented for inverse design of synthesizable multifunctional composites containing both liquid metal and solid inclusions. By integrating physics‐based modeling, data‐driven prediction, and Bayesian optimization, the approach enables intelligent design of experiments to identify optimal compositions and realize these ...

, 2023 The primary tool for analysing groups acting on trees is Bass--Serre Theory. It is comprised of two parts: a decomposition result, in which an action is decomposed via a graph of groups, and a construction result, in which graphs of groups are used to ...

Amenability of groups acting on trees
, 2002 This note describes the first example of a group that is amenable, but cannot be obtained by subgroups, quotients, extensions and direct limits from the class of groups locally of subexponential growth. It has a balanced presentation \[Δ= < b,t|[b,t^2]b^{-1},[[[b,t^{-1}],b],b]>.\] I show that it acts transitively on a 3-regular tree, and that $Γ=&
