The collection addresses open problems, challenges, and benchmarks for data-driven and equation-informed tools for data assimilation, prediction, (subgrid-scale) modeling, inpainting, classification, and (optimal) control of Eulerian and Lagrangian problems in complex flows.
The goal is to move from proof-of-concept to quantitative benchmarks and grand challenges, including scaling of algorithms and complexity of datasets.
The original research papers, presented in a colloquium format, focus on the latest experimental, theoretical, or computational advances and address the interpretability, superiority, and usability of data-driven tools when applied to realistic fluid dynamics problems in engineering, geophysics, biophysics, and other fields. Key topics covered include: (i) Modeling and controlling complex flows with data-driven methods. (ii) Prediction and data-assimilation of multiscale flows. (iii) Reconstruction, super-resolution of fluid flows with data-driven and physics-informed tools. (iv) Optimization of navigation and other tasks in complex flows. (v) Animal behavior in flows.

Predictions of the behaviour of super-heavy elements that have not yet been observed on Earth may help explain the properties of dense asteroids further motivating potential asteroid miners.
Some asteroids have measured densities higher than those of any elements known to exist on Earth. This suggests that they are at least partly composed of unknown types of ‘ultradense’ matter that cannot be studied by conventional physics. Jan Rafelski and his team at the Department of Physics, The University of Arizona, Tucson, USA, suggest that this could consist of superheavy elements with atomic number (Z) higher than the limit of the current Periodic Table. They modelled the properties of such elements using the Thomas-Fermi model of atomic structure, concentrating particularly on a proposed ‘island of nuclear stability’ at and around Z=164 and extending their method further to include more exotic types of ultra-dense material. This work has now been published in EPJ Plus.

A new graphene-based optical logic gate uses collective oscillations of electrons to process light waves in a far smaller space than existing designs. The device also benefits from low information loss and high stability.
Research into artificial intelligence (AI) network computing has made significant progress in recent years, but has so far been held back by the limitations of logic gates in conventional computer chips. Through new research published in EPJ D, a team led by Aijun Zhu at Guilin University of Electronic Technology, China, introduce a graphene-based optical logic gate, which addresses many of these challenges.

Combining a bulky chain with a stable polymer can enhance liquid crystal performance
From laptop screens to navigation systems, liquid crystals are ubiquitous in modern life. These materials flow like liquids, but their molecules align with one another in a way that resembles the orientational order of a crystal. Electrically switching between different molecular orientations – or phases – in a liquid crystal changes how the material transmits light, hence their use/utility in visual displays.
In a study published in EPJ E, Ashok Kumar, of Jawaharlal Nehru Technological University, Kakinada, India, and his colleagues now report on a new design that adds a bulky chemical side chain to a polymer liquid crystal. The approach combines components that, separately, avoid optical degradation and enhance thermal stability; and could lead to improved switching speeds.
EPJ Plus Focus Point Issue: Progress in Medical Physics in Times of CoViD-19 and Related Inflammatory Diseases

Guest editors: E. Cisbani, S. Majewski, A. Gori, F. Garibaldi
COVID-19 is a systemic disease attacking the total body; one of the signatures of the disease is inflammation, an extremely complex phenomenon, in different parts of the body, that can benefit of a multidisciplinary imaging approach. Understanding inflammation is an important step for curing from COVID-19; its role must be understood, in particular for the strategies and technologies to be used against COVID-19, its consequences and potential future pandemics. Among the molecular imaging technologies that can play a central role is the Nuclear Medicine imaging. New advanced technologies that are under development could translate into increased sensitivity of early detection, avoiding the long-term side effects of inflammation. In this context, the Focus Point presents the most promising developments for more effective imaging in Nuclear Medicine. The intrinsic multidisciplinary and the related difficulty to address complex, specific, questions to the different scientific communities have been taken into account in the selection of the contributions, their scientifically sounding relevance and at the same time their capability to be understandable outside their reference discipline.
EPJ Plus Highlight - Introducing the European strategy for accelerator-based photon science (ESAPS 2022)
- Published on 25 September 2023
Through new plans detailed in ESAPS 2022, the LEAPS consortium aims to strengthen Europe as a global leader in accelerator-based photon science.
The League of European Accelerator-based Photon Sources (LEAPS) is made up of 19 large-scale synchrotron (SR) and Free-electron Laser (FEL) facilities, situated across 10 European countries. This contribution to the EPJ Plus Focus Point “Accelerator-based Photon Science Strategy, Prospects and Roadmap in Europe: a Forward View to 2030” introduces the European Strategy for Accelerator-based Photon Science (ESAPS 2022): a pan-European plan formulated by LEAPS aimed at addressing the future challenges and needs in science and innovation, which strengthens Europe as a global leader in many areas of research and technology. Through the plans set out in ESAPS 2022, LEAPS could soon provide valuable new resources for more than 35,000 researchers using its facilities today, spanning fields as wide-ranging as materials science, drug design, biochemistry, quantum technology, geology, and planetary science.

The AGATA project could eventually lead to a deeper understanding of the strong nuclear force. This paper details the project’s highly sophisticated management structure, which will be essential to achieving this goal.
The Advanced Gamma Tracking Array (AGATA) is a European gamma-ray spectrometer that is already achieving unparalleled levels of sensitivity in nuclear gamma-ray spectroscopy. Ensuring success in the project’s construction and operation has involved developing a highly sophisticated structure of management and organisation. This contribution to the EPJ A topical collection “AGATA: Advancements in Science and Technology” describes the roles and responsibilities of each of AGATA’s management committees, and details the project’s scientific organisation. As AGATA promises to make major breakthroughs in our understanding of the strong nuclear force and nuclear structure in the coming decades, the paper offers a new degree of transparency for the many research groups which stand to benefit from its future discoveries.
