Formality properties of finitely generated groups and Lie algebras

open access: yes, 2019
We explore the graded and filtered formality properties of finitely generated groups by studying the various Lie algebras over a field of characteristic 0 attached to such groups, including the Malcev Lie algebra, the associated graded Lie algebra, the ...

Steroidopathies and hormonal imbalance in children and adolescents with autism spectrum disorder

open access: yesJCPP Advances, EarlyView.
Abstract Background Autism Spectrum Disorder (ASD) is a complex neurodevelopmental condition with a multifactorial etiology, many aspects of which remain unclear. Emerging evidence suggests a potential association between ASD and clinical manifestations resulting from hormonal imbalances, henceforth named “steroidopathies.” The present study aims to ...

Fuzzy Logic Approach for Power Transformer Asset Management Based on Dissolved Gas-in-Oil Analysis

open access: yesChemical Engineering Transactions, 2013
Dissolved gas analysis (DGA) of transformer oil is one of the most effective power transformer condition monitoring tools which can be facilitated to determine transformer criticality ranking and hence identifying a suitable condition-based asset ...

Adaptive Dynamic Meta-Heuristics for Feature Selection and Classification in Diagnostic Accuracy of Transformer Faults

open access: yesIEEE Access, 2021
Detection of transformer faults avoids the transformer’s undesirable loss from service and ensures utility service continuity. Diagnosis of transformer faults is determined using dissolved gas analysis (DGA).

On the notion of gauge symmetries of generic Lagrangian field theory

open access: yes, 2008
General Lagrangian theory of even and odd fields on an arbitrary smooth manifold is considered. Its non-trivial reducible gauge symmetries and their algebra are defined in this very general setting by means of the inverse second Noether theorem.

A Randomized Single‐Center Proof of Principle Study to Evaluate the Effectiveness and Safety of a Hydrogel Laser Treatment Patch in Laser Hair Removal

open access: yesLasers in Surgery and Medicine, EarlyView.
ABSTRACT Background Laser hair removal (LHR) is a commonly performed aesthetic procedure known to generate a hazardous laser plume composed of toxic chemicals, ultrafine particles, and potentially infectious biological materials. Current mitigation strategies, such as smoke evacuation systems, are costly and often used inconsistently, highlighting the ...
