FEBS Letters, EarlyView.Proteostasis and the gut microbiota play a key role in shaping host physiology. Microbiota‐derived metabolites, vitamins, and RNA modulate host proteostasis. Findings from model systems, including C. elegans, indicate microbes can either stabilize or disrupt host proteostasis.

Interval estimation of trigonometrical splines [PDF]
MATEC Web of Conferences, 2019 Quite often, it is necessary to quickly determine variation range of the function. If the function values are known at some points, then it is easy to construct the local spline approximation of this function and use the interval analysis rules.

Approximation Errors of Online Sparsification Criteria [PDF]
IEEE Transactions on Signal Processing, 2015 Many machine learning frameworks, such as resource-allocating networks, kernel-based methods, Gaussian processes, and radial-basis-function networks, require a sparsification scheme in order to address the online learning paradigm. For this purpose, several online sparsification criteria have been proposed to restrict the model definition on a subset ...

From mice to humans—divergent strategies for intestinal homeostasis and regeneration
FEBS Letters, EarlyView.Recent advances such as organoid genome editing, xenotransplantation, imaging, and whole‐genome sequencing have enabled direct studies of human intestinal stem cells (ISCs). These studies reveal species‐specific features, including slower ISC proliferation, distinct injury responses, slower somatic mutation accumulation in humans, and an inverse ...

On approximating the error function [PDF]
Mathematical Inequalities & Applications, 2018 Summary: In the article, we find the best possible parameters \(p\) and \(q\) on the interval \((7/5, (7\pi-20)/(5\pi-15))\) such that the double inequality \[ \sqrt{1-\lambda(p)e^{-px^2}-(1-\lambda(p))e^{-\mu(p)x^2}}

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

A Closed-Form Cubic–Logistic Approximation to the Normal Cumulative Distribution Function
MathematicsAccurate evaluation of the standard normal cumulative distribution function is fundamental in many areas of mathematics, statistics, and applied computation, yet no closed-form expression in elementary functions exists.

Design and analysis strategies for robust microbiome ageing research
FEBS 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

Approximations for standard normal distribution function and its invertible
Journal of Algorithms & Computational TechnologyIn this paper, we introduce a new approximation of the cumulative distribution function of the standard normal distribution based on Tocher's approximation.
