Can Third Country Nationals Be Banned From Schengen? Assessing Member State Unilateral Measures Against Russian Citizens and the Commission's Response

open access: yesJCMS: Journal of Common Market Studies, Volume 63, Issue 6, Page 1726-1742, November 2025.
Abstract Russia's invasion of Ukraine in February 2022 led the European Union (EU) to take several measures to support Ukraine and sanction Russia. Still further measures have been discussed, including the question of whether Russians, and especially Russian tourists, should be banned from travelling in the Schengen area.

Environmentally Sustainable Development: The Role of Supply Chain Digitalization in Firms' Green Productivity

open access: yesSustainable Development, Volume 33, Issue 5, Page 7807-7825, October 2025.
ABSTRACT In the midst of the global push for environmental protection and sustainable development, supply chain digitalization (SCD) has become a key enabler of both operational efficiency and green production. The existent literature, however, has mainly focused on SCD's impact on operational efficiency, neglecting its role in advancing environmental ...

Evening Chronotype Associates With Worse Physical and Mental Health and Headache‐Related Disability Among Migraine Patients

open access: yesJournal of Sleep Research, Volume 34, Issue 5, October 2025.
ABSTRACT Migraine has been linked to chronotype, but with mixed results. Here, we tested chronotype in association with physical and mental health and headache characteristics in a large database of migraine patients and controls. A sample of the UK Biobank (n = 360,081; 58.3% female, mean age: 56.38) was used.

Performance Optimization of Dual Active Bridge Converter Based on Improved Linear Active Disturbance Rejection Control

open access: yesEngineering Reports, Volume 7, Issue 9, September 2025.
In this paper, an improved linear active disturbance suppression control method is introduced to optimize the current stress and dynamic response of the dual active bridge DC‐DC converter through extended phase‐shift modulation, which improves the overall efficiency of the converter in microgrid systems.
