This EPJ Plus Focus Point on Marine Citizen Science – Applications, Processes, and Data Integration focuses on the scientific and methodological advances in all areas of ocean and coastal research where citizen science can be shown to expand monitoring capacity and complement traditional observing systems. It specifically addresses challenges related to data quality, validation, and integration, and explores the role of participatory science in model validation, forecasting, and digital twins of the ocean. This collection also examines topics demonstrating strong connections between methodological, environmental or societal issues. By bridging communities and scientists, this collection contributes to building inclusive, resilient, and forward-looking ocean observing systems aligned with the objectives of the UN Ocean Decade and the CoastPredict program.

Submission Details:

Articles should be submitted via the journal's online submission system and clearly identified as intended for the topical issue “Marine Citizen Science – Applications, Processes, and Data Integration”.

Detailed author guidelines, including information on paper types, are available in the Submission Guidelines. For manuscript preparation, authors are encouraged to use the journal’s dedicated LaTeX template (preferably in single-column format).

Open Access: EPJ Plus is a hybrid journal offering Open Access publication via the Open Choice programme and a growing number of Open Access Agreements. If the institution of the CORRESPONDING AUTHOR is part of such an agreement, the Open Access fee may be covered by the agreement partner. All agreements are listed with more details under Open Access Agreements. Eligibility will be verified when the corresponding author is requested to complete the relevant affiliation information after acceptance of the paper during the production process. Corresponding authors not affiliated to institutes with Transformative Agreements are redirected to proceed with “Please select your publishing model” and will have to decide between paying the current Open Access fee or choosing the subscription option without any publication charges.

The study of dynamical systems with memory has advanced rapidly in recent years, largely through two major frameworks: fractional calculus and time-delayed dynamics. Each has developed into a mature discipline with its own theories, methods, and applications, yet they have often evolved in parallel rather than in dialogue.

Fractional derivatives provide a natural framework for hereditary effects and anomalous transport through continuous memory kernels, while time delays capture explicit dependencies on past states arising from finite signal propagation or feedback. Despite their different mathematical formulations, both approaches aim to describe how the past influences the present. Striking parallels have begun to emerge: fractional operators can sometimes be interpreted as infinite-dimensional delay distributions, while time-delayed systems can reproduce long-memory effects in discrete form. This suggests a deeper, underexplored connection between the two perspectives.

In the wave of contemporary materials science and interdisciplinary research, hexagonal boron nitride (hBN) is gradually emerging as a "bridge material" connecting multiple research fields, thanks to its unique physicochemical properties. As a wide-bandgap semiconductor with a graphene-like layered structure, hBN not only exhibits excellent chemical stability, high thermal conductivity, and superior insulating performance but also demonstrates irreplaceable advantages in terms of atomic-level flatness and surface defect regulation. These characteristics enable it to perfectly meet the requirements for constructing low-dimensional material systems, providing an ideal experimental platform for exploring cutting-edge scientific issues in quantum physics, optoelectronics, and other fields. Consequently, hBN has become a highly regarded and excellent carrier in interdisciplinary research.

The science of complex networks has fundamentally reshaped our understanding of interconnected systems across disciplines. Traditionally, network science has relied on pairwise interactions to model system dynamics. However, many real-world systems—from functional brain networks and ecological communities to social systems and collaborative networks—are driven by higher-order interactions (HOIs), where the relationship between elements cannot be decomposed into simple binary links. Concurrently, self-organization, the process where a system's internal interactions lead to the spontaneous emergence of ordered structure and function without external control, is a hallmark of complex adaptive systems. The interplay between self-organization and HOIs is a frontier of modern network science, crucial for developing accurate models of real-world complexity.

The European Physical Journal E 25th Anniversary Collection: Past Insights, Present Voices, Future Horizons

Celebrating 25 years of the European Physical Journal E (EPJE)

From foundational insights in soft condensed matter to emerging frontiers in biological physics.

The year 2025 marks the 25th anniversary of the European Physical Journal E (EPJE). Since its launch in 2000, EPJE has grown from a core focus on polymers, colloids, and complex fluids into a broad and dynamic platform for research in soft matter, flowing matter and biological physics. Over the past quarter-century, the journal has supported the evolution of key fields — from polymer rheology to active matter, from granular flows to biophysical modeling — while cultivating a diverse and interdisciplinary scientific community across Europe and worldwide.

Submissions are invited for a Topical Collection of EPJ D on 3D physics in magnetic confinement fusion (MCF).

The pursuit of magnetic confinement fusion (MCF) as a transformative clean energy source faces critical challenges in plasma confinement and stability. Addressing these necessitates a profound understanding and active exploitation of three-dimensional (3D) magnetic field effects, moving beyond traditional axisymmetric approaches. This special issue focuses on the rapidly evolving frontier of 3D physics in MCF, encompassing resonant magnetic perturbations (RMPs), magnetohydrodynamics (MHD) instabilities and their control, turbulences in 3D magnetic flux surfaces, 3D boundary transport and stellarator optimization using quasi-symmetric configuration, etc.

The quest to understand the behaviours and performance of materials and devices under extreme conditions is a boundary-pushing venture that broadens the scope of human knowledge. Spanning the icy vacuum of space to the high-temperature and high-pressure core of a star, the field of materials and devices for extreme conditions emerges as a critical area of study. The focus lies in deciphering how materials and devices respond to extreme conditions, including, but not limited to, intense radiation, extreme cold, ultrahigh temperature, ultrahigh magnetic fields, and ultrahigh pressures, as well as the conditions induced by high-power lasers. This exploration delves into the physical effects and damage resulting from the interaction between different harsh environments and multidimensional, cross-scale material systems.
