Non-extensive entropy and holographic thermodynamics: topological insights

European Physical Journal C: Particles and Fields
In this paper, we delve into the thermodynamic topology of AdS Einstein–Gauss–Bonnet black holes, employing non-extensive entropy formulations such as Barrow, Rényi, and Sharma–Mittal entropy within two distinct frameworks: bulk boundary and restricted ...

Molecular dynamics simulations of positively selected codons in FcγRI reveal novel biochemical binding properties

FEBS Open Bio, EarlyView.
Evolutionary analysis across 32 placental mammals identified positive selection at residues H148 and W149 in the immune receptor FcγR1. Ancestral reconstruction combined with molecular dynamics simulations reveals how these mutations may influence receptor structure and dynamics, providing insight into the evolution of antibody recognition and immune ...

Reeb orbits that force topological entropy [PDF]

, 2022
: We develop a forcing theory of topological entropy for Reeb flows in dimension three. A transverse link L in a closed contact 3-manifold (Y, xi) is said to force topological entropy if (Y, xi) admits a Reeb flow with vanishing topological entropy, and ...

Dual native G‐quadruplex folding is associated with chromatin looping at the MYC locus

FEBS Open Bio, EarlyView.
BG4‐detectable G‐quadruplex (G4) in HaCaT and NHEK keratinocytes identified folded and unfolded G4s enriched at promoters/TSSs and active enhancers, whereas unfolded G4s also overlapped weak/poised enhancers. At MYC–PVT1, 3C‐qPCR detected enhancer–promoter looping only when G4s were simultaneously folded at both regulatory elements under native ...

A remark on positive topological entropy of N-buffer switched flow networks

Discrete Dynamics in Nature and Society, 2005
We present a simpler elementary proof on positive topological entropy of the N-buffer switched flow networks based on a new simple theorem on positive topological entropy of continuous map on compact metric space.

Influence Maximization Dynamics and Topological Order on Erdös-Rényi Networks

Mathematics, 2023
This paper concerns the study of the linear threshold model in random networks, specifically in Erdös-Rényi networks. In our approach, we consider an activation threshold defined by the expected value for the node degree and the associated influence ...

Topological sequence entropy of nonautonomous dynamical systems [PDF]

, 2023
Let $f_{0,\infty}=\{f_n\}_{n=0}^{\infty}$ be a sequence of continuous self-maps on a compact metric space $X$. Firstly, we obtain the relations between topological sequence entropy of a nonautonomous dynamical system $(X,f_{0,\infty})$ and that of its ...
