Quasi-normal modes from non-commutative matrix dynamics
Journal of High Energy Physics, 2017 We explore similarities between the process of relaxation in the BMN matrix model and the physics of black holes in AdS/CFT. Focusing on Dyson-fluid solutions of the matrix model, we perform numerical simulations of the real time dynamics of the system ...

Black Hole Growth, Baryon Lifting, Star Formation, and IllustrisTNG
The Astrophysical Journal, 2023 Quenching of star formation in the central galaxies of cosmological halos is thought to result from energy released as gas accretes onto a supermassive black hole.

Using fluorescence fluctuation spectroscopy to quantify molecular dynamics within cells
FEBS Open Bio, EarlyView.Microscopy techniques like fluorescence correlation spectroscopy (FCS) and number and brightness analysis (N&B) allow to quantify concentrations, diffusion rates, and oligomerization of fluorescently labeled molecules in the living cell. In this protocol the principles of how to set up these types of experiments are described including calibration ...

Topological Point Defects of Liquid Crystals in Quasi-Two-Dimensional Geometries
Frontiers in Physics, 2020 We review the interactions and dynamics of topological defects in liquid crystals (LCs) in quasi-two-dimensional (2D) geometries. Such spatial restrictions can be realized in thin freely suspended smectic C films, in thin sandwich cells filled with ...

In vitro generation of regulatory T cells: A challenging tool for studying immune aging in humans
FEBS Open Bio, EarlyView.In vitro induction of human regulatory T cells using standard protocols generates suppressive, Foxp3‐expressing CD4+ T cells independently of TGF‐β supplementation and donor age. Regulatory T (Treg) cells play a key role in immune tolerance and homeostasis.

Characterization of the key membrane protein cytochrome Cyc2 from Ghiorsea bivora
FEBS Open Bio, EarlyView.This study reports the first detailed biochemical analysis of Cyc2TAG1_1, a cytochrome protein involved in microbial iron oxidation. We produced and purified this enzyme in E. coli, then measured its iron‐oxidizing efficiency, and characterized its electrical and structural properties.

Numerical simulation of quenching process using an adaptative levelset method
, 2011 International audienceWe present in this paper the thermal modelling of the quenching process. Different stages of such process need to be treated, from nucleate boiling to generation and growth of a vapour film.
