The ubiquitin‐proteasome system and autophagy as guardians of the cellular proteome

FEBS Letters, EarlyView.
This Perspective covers the three principles governing the crosstalk between the ubiquitin‐proteasome system and autophagy in cellular proteostasis: (1) a shared ubiquitin code routing substrates via shuttle factors or autophagy receptors; (2) spatial compartmentalization into phase‐separated degradation hubs and organelle‐specific modules (exemplified

Probabilistic projections of distributions of kin over the life course [PDF]

Demographic Research
BACKGROUND: Mathematical kinship demography is an expanding area of research. Recent papers have explored the expected number of kin a typical individual should experience.

Branching Bisimilarity of Normed BPA Processes as a Rational Monoid [PDF]

Logical Methods in Computer Science, 2017
The paper presents an elaborated and simplified version of the structural result for branching bisimilarity on normed BPA (Basic Process Algebra) processes that was the crux of a conference paper by Czerwinski and Jancar (arxiv 7/2014 and LiCS 2015 ...

Branching Random Walks with Two Types of Particles on Multidimensional Lattices

Mathematics, 2022
We consider a continuous-time branching random walk on a multidimensional lattice with two types of particles and an infinite number of initial particles.

Cell geometry and membrane protein crowding constrain Escherichia coli growth rate, overflow metabolism, respiration, and maintenance energy

FEBS Letters, EarlyView.
The physical dimensions and shape of bacterial cells define the surface area available to acquire nutrients and the volume available for synthesizing proteins and DNA. Here, we use computational systems biology to decode the importance of cell geometry as a major determinant of prokaryotic phenotype, including growth rate and metabolic efficiency. This

Lévy-driven polling systems and continuous-state branching processes

Stochastic Systems, 2011
In this paper we consider a ring of N ≥ 1 queues served by a single server in a cyclic order. After having served a queue (according to a service discipline that may vary from queue to queue), there is a switch-over period and then the server serves the ...

Information properties of the nonparametric maximum likelihood estimators in branching processes with random migration

Biomath
We consider the nonparametric maximum likelihood estimation of single type discrete time branching processes with random migration. These processes occur naturally in situations where besides the random reproduction both emigration and immigration of ...

Spreading of memes on multiplex networks

New Journal of Physics, 2019
A model for the spreading of online information or ‘memes’ on multiplex networks is introduced and analyzed using branching-process methods. The model generalizes that of (Gleeson et al 2016 Phys. Rev. X) in two ways.

Application of branching processes to solve boundary value problems for the semi-linear Helmholtz equation [PDF]

E3S Web of Conferences
This work devoted to construct a probabilistic model for solving boundary value problems for the semi-linear Helmholtz equation. Probabilistic representations of problem solving in the form of the mathematical expectation of some random variable are ...

Microbiome−host proteostasis crosstalk—An emerging perspective on mechanisms and interventions toward healthy longevity

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.
