Active Matter [PDF]

open access: yesThe European Physical Journal E, 2013
The study of systems with sustained energy uptake and dissipation at the scale of the constituent particles is an area of central interest in nonequilibrium statistical physics. Identifying such systems as a distinct category -- Active Matter -- unifies our understanding of autonomous collective move- ment in the living world and in some surprising ...

Amine- and Amino Acid-Based Compounds as Carbonic Anhydrase Activators

open access: yesMolecules, 2021
After being rather neglected as a research field in the past, carbonic anhydrase activators (CAAs) were undoubtedly demonstrated to be useful in diverse pharmaceutical and industrial applications.

Selection of activators in finding the burning number

open access: yesAKCE International Journal of Graphs and Combinatorics, 2023
Graph burning is a model for spread of information in a network. In recent times social networks play a major role in the thought process of people and influences the social movements, election and politics.

Activating Membranes [PDF]

open access: yesPhysical Review Letters, 2014
We present a general dynamical theory of a membrane coupled to an actin cortex containing polymerizing filaments with active stresses and currents, and demonstrate that active membrane dynamics [Phys. Rev. Lett \textbf{84}, 3494 (2000)] and spontaneous shape oscillations emerge from this description. We also consider membrane instabilities and patterns

Active listening

open access: yesHearing Research, 2020
AbstractThis paper introduces active listening, as a unified framework for synthesising and recognising speech. The notion ofactive listeninginherits from active inference, which considers perception and action under one universal imperative: to maximise the evidence for our (generative) models of the world.

Sirtuin activators as an anti-aging intervention for longevity [PDF]

open access: yesExploration of Drug Science
Sirtuins are a family of NAD+-dependent class III histone deacetylases that regulate histones and other proteins. The mammalian sirtuins comprise seven members that have a role in energy metabolism, DNA repair, inflammation, cell survival, apoptosis ...

Development and Experimental Validation of Regularized Machine Learning Models Detecting New, Structurally Distinct Activators of PXR

open access: yesCells, 2022
The pregnane X receptor (PXR) regulates the metabolism of many xenobiotic and endobiotic substances. In consequence, PXR decreases the efficacy of many small-molecule drugs and induces drug-drug interactions.
