Number theory and automata theory
Nous mettons en évidence un certain nombre de liens entre la théorie des nombres et celle des automates :- étude de sous-suites de la suite "somme des chiffres", étude des itérées de cette suite ;- utilisation de suites automatiques particulières (baptisées q-miroirs) dans le problème de l'itération des fonctions continues unimodales réelles ;- étude d'

POM‐Based Water Splitting Catalyst Under Acid Conditions Driven by Its Assembly on Carbon Nanotubes
A newly‐engineered POM‐based electrocatalyst incorporating non‐innocent counter cations exhibits fast kinetics for either the OER or HER under strongly acidic conditions (1 m H2SO4), depending on whether it is assembled on carbon nanotubes (1@CNT) or physically mixed with them (1/CNT). In water‐splitting tests using a two‐electrode setup, these systems

Automata Theory and Formal Languages
In this book we present some basic notions and results on Automata Theory, For- mal Language Theory, Computability Theory, and Parsing Theory. In particular, we consider the class of regular languages which are related to the class of finite automata, and the class of the context-free languages which are related to the class of pushdown automata.

Unravelling the Secret of Sulfur Confinement and High Sulfur Utilization in Hybrid Sulfur‐Carbons
Thermal condensation of inverse vulcanized sulfur‐carbon hybrids enables a bottom‐up sulfur confinement strategy, in which a protective carbon phase is progressively constructed around sulfur species. The resulting carbon nanodomains covalently tether sulfur chains and stabilize radical intermediates. This integrated architecture effectively suppresses

Tailored Xenogeneic‐Free Polymer Surface Promotes Dynamic Migration of Intestinal Stem Cells
This study introduces a PoLymer‐coated Ultra‐stable Surface (PLUS), a nitrogen plasma‐treated poly(ethyleneglycoldimethacrylate), as a stable xenogeneic‐free platform for intestinal stem cell culture. PLUS enhances cell attachment, supports actin‐driven migration, and retains functionality after 3 years of storage. Promoting cytoskeletal reorganization,
