Road to Open: Despite Challenges, Mathematics Journals Remain Open Access through Subscribe to Open in 2025
- Details
- Published on 16 April 2025

As part of EDP Sciences’ ongoing commitment to furthering open science, this news update is the latest in our “Road to Open” series, which highlights developments in open access publishing through models such as Subscribe to Open (S2O). This edition focuses on the continued, though increasingly fragile, support for open access in mathematics journals. Despite a notably more difficult renewal campaign in 2025, the collaborative efforts of libraries, academic institutions, and the wider mathematical community have once again made it possible to disseminate high-quality research without article processing charges.

SCOPE
Sensitivity Analysis (SA) and Uncertainty Quantification (UQ) are highly cross-disciplinary fields. UQ is the process of characterizing all significant uncertainties in a model, simulation, or experiment and of quantifying their effect on computed or experimental results. SA in the context of UQ is the determination of how much uncertainty an individual source contributes to the total uncertainty in a simulated or experimental quantity. Both SA and UQ have established themselves as unifying tools within applied mathematics and computer science over the last few decades. They have created synergies between different fields such as statistics, probability, numerical analysis, machine learning and deep learning. They have also encouraged collaborations between mathematics and other disciplines such as biology, earth and environmental sciences, and engineering.
The Eleventh International Conference on Sensitivity Analysis of Model Output (SAMO) was held in Grenoble (France) in April, 2025. Since 1995, SAMO conferences are devoted to advances in research on sensitivity analysis methods and their interdisciplinary applications, bringing together researchers involved in the development and application of such methods. Following the 2025 conference but not restricted to SAMO 2025 participants, the aim of this special issue of ESAIM P&S journal is to present original /or theoretical ideas and advanced methodological developments in sensitivity analysis and uncertainty quantification connected subjects. Within this framework, topics of interest include (but are not limited to) active learning, complex data and/or models, conformal prediction, feature selection, kernel methods, optimal sampling, physics informed learning, reduced order modelling. Ideally, papers are expected to achieve a balance between academic material and practical applications.
