Group extensions and discrete subgroups of Lie groups [PDF]

Proceedings of the American Mathematical Society, 1972
Let F be a discrete uniform subgroup of a connected simply connected solvable Lie group S. It is shown how S is essentially determined by F, using the point of view of group extensions. Let r be a discrete uniform subgroup of a connected simply connected solvable Lie group S.

Integrating Reinforcement Learning With Explainable Artificial Intelligence for Real‐Time Clinical Decision Support in Dynamic Healthcare Environments

Advanced Intelligent Systems, EarlyView.
A hybrid Reinforcement Learning–Explainable AI framework integrates SHAP and LIME explanations directly into a Deep Q‐Network inference loop for real‐time ICU decision support. Trained on 18 142 mechanically ventilated stays from the eICU database, the system attains 93.0% decision accuracy, 20% fewer errors than RL alone, and a 91% clinician trust ...

Automorphic inflation

Physics Letters B, 2015
A framework of inflation is formulated based on symmetry groups and their associated automorphic functions. In this setting the inflaton multiplet takes values in a curved target space constructed from a continuous group G and a discrete subgroup Γ.

Place‐based risk: Examining relationships between adolescent perceptions of community risk factors and adolescent substance use across geographic contexts

American Journal of Community Psychology, EarlyView.
Abstract Mixed evidence for the influence of structural and social factors on adolescent substance use behaviors exists across the rural–urban continuum. Therefore, this study explores how adolescent perceptions of structural and social community risk factors are associated with lifetime and past 30‐day use of alcohol, marijuana, cigarettes, and ...

Topological fermion condensates from anomalies

Journal of High Energy Physics, 2018
We show that a class of fermion theory formulated on a compact, curved manifold will generate a condensate whose magnitude is determined only by the volume and Euler characteristic of the space.

Discrete and free subgroups of SL₂

, 2020
In this thesis, we study finitely generated subgroups of the matrix group SL₂ (over various locally compact fields) which are both discrete and free. We first examine the existing literature on two- and three-generated subgroups of SL₂(R) and SL₂(C). Some such subgroups are known to be free, and this can be proved by applying a ‘combination’ theorem ...

Distinct Neuropsychiatric Profiles Associated With 17p11.2 Deletions and RAI1 Variants in Smith–Magenis Syndrome

American Journal of Medical Genetics Part A, EarlyView.
ABSTRACT Smith–Magenis syndrome (SMS) results from either a recurrent 17p11.2 deletion or pathogenic variants in the retinoic acid induced 1 gene (RAI1). While neurodevelopmental impairment and behavioral dysregulation are well recognized, systematic genotype‐stratified analyses across psychiatric domains remain limited.

Hidden in the Labour Market: An Intersectional Latent Class Analysis of Discouraged Workers in Australia

Australian Journal of Social Issues, EarlyView.
ABSTRACT This study employs an intersectionality‐informed latent class analysis (LCA) to examine the hidden diversity of discouraged workers in Australia. Drawing on nationally representative data from the Household, Income and Labour Dynamics in Australia Survey, we identified six empirically distinct subgroups defined by intersecting demographic and ...

On Discrete Zariski‐Dense Subgroups of Algebraic Groups [PDF]

Mathematische Nachrichten, 1997
AbstractWe investigate under which conditions an algebraic group G defined over a locally compact field k admitr a subgroup Γ⊂ G(k) which is dense in the Zariski topology, but discerte in the topology induced by the locally compact topology on k. For non—solvable groups we provide a complete answer.

Cohesion Without Consensus: Attitudinal Profiles of Social Cohesion in Australia

Australian Journal of Social Issues, EarlyView.
ABSTRACT Headline indicators of social cohesion in Australia have remained stable in recent years despite rising political polarisation and declining institutional trust worldwide. Yet recent protests and incidents of ethnically and politically motivated violence suggest that cohesion may be under strain. If cohesion is understood not as the pursuit of
