EPJ ST Highlight - Showcasing the possibilities of memristor circuits

The papers presented in this special issue explore several unique capabilities of memristor-based systems: including multistability, nonlinearity, and chaotic dynamics

First demonstrated in 2008, the memristor is an electrical component which can limit the amount of current in a circuit, while remembering the amount of charge it conveyed in the past. Yet despite its numerous potential applications, the memristor’s commercial rollout has so far been restricted by the high manufacturing costs of its nano-scale electrical components.

To improve both the range of applications and theoretical understanding of memristors, there is a need to investigate their fundamental features, while diversifying the tools used to model their behaviours. In this special issue, the journal EPJ ST presents 25 new papers showcasing the widely-varied possibilities by memristor systems, and the mathematical principles required to understand and model them.

Dr Yelena Mejova

EPJ is pleased to announce that Dr Yelena Mejova has been appointed as a co-Editor-in-Chief for EPJ Data Science, effective January 2023. She will be responsible for overseeing the editorial process of the journal, working closely with Dr Ingmar Weber, who continues to serve as co-Editor-in-Chief.

Yelena Mejova is a Senior Research Scientist at the ISI Foundation in Turin, Italy. Specializing in social media analysis and mining, her work concerns the quantification of health and wellbeing signals in social media, as well as tracking of social phenomena, including politics and news consumption. In 2022, she co-chaired International AAAI Conference on Web and Social Media (ICWSM) and the Web & Society track at The Web Conference. As a part of the CRT Foundation's Lagrange Project for Data Science and Social Impact, she is also working with the humanitarian sector including the World Food Program, OCHA, and IMMAP to develop NLP and modeling tools to aid in humanitarian data management and forecasting.

EPJ Web of Conferences Highlight - ConfXV: XVth Quark Confinement and the Hadron Spectrum Conference

More than 230 participants from 31 countries attended ConfXV at the University of Stavanger in August 2022.

Emerging from the pandemic, it was a pleasure to host the 15th edition of the Quark Confinement and the Hadron spectrum conference as in-person event at the University of Stavanger in August 2022.

This conference series has become an important forum for scientists working on the strong nuclear interactions, stimulating exchange among theorists and experimentalists from various fields.

EPJ 25th anniversary logo

The EPJ Publishers would like to thank all editors, authors, referees and readers for contributing to EPJ’s success.

Merry Christmas and Happy New Year!

2023 will see 25 years since of the launch of the European Physical Journal (EPJ), with the first issues of the core EPJ titles being published in 1998. To mark this anniversary, and in keeping with the long-held EPJ tradition of supporting early career researchers, EPJ is making available a number of grants to support meetings for young researchers throughout 2023.

EPJ E Highlight - Modelling the collective movement of bacteria

Research into the movement of packages of bacteria could help better understand the formation of troublesome biofilms.

Biofilms form when microorganisms such as certain types of bacteria adhere to the surface of objects in a moist environment and begin to reproduce resulting in the excretion of a slimy glue-like substance.

These biofilms aren’t just unpleasant and unappealing however, they can be seriously troublesome. For example, in the medical field, the formation of biofilm can reduce the effectiveness of antibiotic treatments. The key to understanding biomass formation lies in understanding how bacteria behave en masse.

A new paper in EPJ E by Heinrich-Heine-Universität, Düsseldorf, Germany, researcher Davide Breoni and his co-authors presents a mathematical model for the motion of bacteria that includes cell division and death, the basic ingredients of the cell cycle.

EPJ D Topical Issue: Advances in Multi-Scale Modelling of Intense Electronic Excitation Processes

Guest Editors: Jorge Kohanoff, Antonio Rivera, Eduardo Oliva Gonzalo, Andrey V Solov'yov and Tzveta Apostolova

Processes occurring in a target after irradiation span many orders of magnitude in space and time, which makes them intractable within a single rigorous approach. Typically, only partial aspects related to the radiation-induced effects in matter are treated. The lack of a systematic methodology to simulate the underlying phenomena hinders advances in various fields, and poses challenges to theoreticians, simulators, and experimentalists. It is therefore important to tackle this problem from a multi-scale perspective. This is the realm of this Topical collection, published in the Eur. Phys. J. D (EJPD Topical collection), which includes articles covering a wide range of methods, namely TDDFT, time-dependent Schrödinger equation in one or two-electron approximation, radiation Monte Carlo, Boltzmann transport equation, radiation-hydrodynamics and ab initio and classical Molecular Dynamics.
