Direct evidence and quantification of homologous recognition between DNA duplexes

Andrew Stannard, Ehud Haimov, Jonathan Hedley, Yaxuan Xiao, Marco Di Antonio, Gleb Oshanin, Claudia Danilowicz, Mara Prentiss, Lorenzo Di Michele, Alexei Kornyshev

Stretches of double-stranded DNA sharing the same sequence can recognize each other in cells. This phenomenon, known as homologous recognition, is essential for DNA recombination and repair. Yet, its mechanism remains debated, with purely physical interactions proposed as a contributing factor.…

Stochastic Pairwise Forces Enhance Tracer Diffusion in Nonmotile Active Matter

Henry Alston, Raphaël Voituriez, Thibault Bertrand

Stochasticity is a defining feature of the pairwise forces governing interactions in biological systems—from molecular motors to cell-cell adhesion—yet its consequences on large-scale dynamics remain poorly understood. Here, we show that reciprocal but randomly fluctuating interactions between…

Effects of fermions in one-loop propagators in the Curci-Ferrari-Delbourgo-Jarvis gauge

Santiago Cabrera, Marcela Peláez, Matthieu Tissier

We present the one-loop computation of the quark propagator in the Curci-Ferrari-Delbourgo- Jarvis (CFDJ) gauge, extending previous analyses to include dynamical quarks. Using the infrared- safe renormalization scheme, we study how finite gauge parameters affect the infrared behavior of QCD…

Perturbative analysis of singularity-free cosmological solutions in unimodular Kaluza-Klein theory

J.C Fabris, S Faller, R Kerner

The unimodular version of the Kaluza-Klein theory is briefly recalled, and its projection on the $4$-dimensional spacetime is constructed. Imposing unimodularity condition on the $5$-dimensional Kaluza-Klein metric, det$g_{AB}=1$ is equivalent with introducing cosmological term in Einstein's…
