Modelling stem cell differentiation related processes—A practical overview for biologists

open access: yesFEBS Letters, EarlyView.
Stem cell differentiation is complex and difficult to control experimentally. This review introduces suitable computational modelling approaches that can support stem cell research, from mechanistic ODE and abstract models to multiscale and deep learning methods.

On the Fontaine–Mazur Conjecture for Number Fields and an Analogue for Function Fields

open access: yesJournal of Number Theory, 2000
The conjecture of Fontaine-Mazur says that if \(k\) is a number field, \(l\) a prime, and \(M\) an unramified \(l\)-adic analytic \(l\)-extension of \(k\), then \(M/k\) is a finite extension. This conjecture is wrong for function fields. But the authors show that, if we start with an equivalent conjecture and restrict to special cases, it is possible ...

Design and analysis strategies for robust microbiome ageing research

open access: yesFEBS Letters, EarlyView.
The gut microbiome changes with age and associates with age‐related morbidity and mortality, establishing it as a potential biomarker and intervention target for ageing. Realising this potential requires methodological rigour, yet distinguishing biological signals from methodological artefacts remains challenging across cohorts. This review provides an

Conserved binding mode but diverse interfaces of MreC‐PBP2 interactions

open access: yesFEBS Letters, EarlyView.
The crystal structure of abMreC reveals a conserved two β‐barrel architecture and provides structural insights into its role within the bacterial elongasome. The abMreC–abPBP2 complex model identifies the molecular basis of MreC‐mediated PBP2 recognition, contributing to the regulation of peptidoglycan synthesis.

On upper bounds of the complexity of functions over nonprime finite fields in some classes of polarized polynomials

open access: yesИзвестия Иркутского государственного университета: Серия "Математика", 2016
Recently, the interest to polynomial representations of functions over finite fields and over finite rings is being increased. Complexity of those representations is widely studied.

The phase sensitivity of a fully quantum three-mode nonlinear interferometer

open access: yesNew Journal of Physics, 2018
We study a nonlinear interferometer consisting of two consecutive parametric amplifiers, where all three optical fields (pump, signal and idler) are treated quantum mechanically, allowing for pump depletion and other quantum phenomena. The interaction of

Microbiome‐blood–brain barrier interactions in aging — mechanisms and therapeutic potential

open access: yesFEBS Letters, EarlyView.
Aging reshapes the gut microbiome (↓SCFA‐producing commensals; ↑pro‐inflammatory outputs), shifting circulating metabolites (↓SCFAs; ↑LPS, ↑TMAO, ↑PAA) that act at the BBB to increase nonspecific transcytosis, alter transport, and promote astrocyte reactivity, heightening brain vulnerability.

Dynamics and resonance fluorescence from a superconducting artificial atom doubly driven by quantized and classical fields

open access: yesPhysical Review Research

A strategy to unveil transient sources of ultra-high-energy cosmic rays

open access: yesEPJ Web of Conferences, 2013
Transient generation of ultra-high-energy cosmic rays (UHECRs) has been motivated from promising candidates of UHECR sources such as gamma-ray bursts, flares of active galactic nuclei, and newly born neutron stars and magnetars.
