Dynamical Aspects of Sandpile Cellular Automata
, 1991 The Bak, Tang, and Wiesenfeld cellular automaton [(1987)] is analysed with respect to the dynamical behavior. The scaling of the power spectrum derives from the assumption that the instantaneous dissipation rate of the individual avalanches obeys a simple scaling relation.

Authorship attribution based on Life-Like Network Automata. [PDF]
PLoS ONE, 2018 The authorship attribution is a problem of considerable practical and technical interest. Several methods have been designed to infer the authorship of disputed documents in multiple contexts.

Percolation and Internet Science
Future Internet, 2019 Percolation, in its most general interpretation, refers to the “flow„ of something (a physical agent, data or information) in a network, possibly accompanied by some nonlinear dynamical processes on the network nodes (sometimes denoted ...

Scientific Reports, 2017 Open-ended evolution (OEE) is relevant to a variety of biological, artificial and technological systems, but has been challenging to reproduce in silico. Most theoretical efforts focus on key aspects of open-ended evolution as it appears in biology.

Invertible linear cellular automata over Zm: Algorithmic and dynamical aspects
, 1997 AbstractWe give an explicit and efficiently computable formula for the inverse ofD-dimensional linear cellular automata overZm(D⩾1, m⩾2). We use this formula to get an easy-to-check necessary and sufficient condition for an invertible one-dimensional linear CA to be expansive, and we prove that this condition is equivalent to topological transitivity.

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.

An epithelial GPR35 isoform supports tumor‐associated transcriptional and metabolic phenotypes
FEBS Letters, EarlyView.GPR35 generates two functionally distinct isoforms with previously unresolved roles. GPR35‐short mediates immune‐cell chemotaxis, while GPR35‐long is enriched in colorectal cancer epithelium, where it supports increased metabolism, proliferation, and tumor‐associated transcriptional programs.

Molecular Oncology, EarlyView.We identify USP29 as the only DUB mirroring CA9 expression, a marker of hypoxia and HIF pathway activation associated with PCA aggressiveness. USP29 stabilizes HIF‐1α and HIF‐2α via a noncanonical mechanism that is independent of PHD/pVHL activity yet relies on proteasomal regulation, establishing USP29 as a previously unrecognized regulator of hypoxic

FEBS Open Bio, EarlyView.This protocol paper outlines methods to establish the success of a time‐resolved serial crystallographic experiment, by means of statistical analysis of timepoint data in reciprocal space and models in real space. We show how to amplify the signal from excited states to visualise structural changes in successful experiments.
