1650 Western manuscripts written between the year 800 AD and the year 1500 AD have been subjected to digital codicological analysis. The analysis involved approximately 600,000 high-resolution images (400 dpi), enabling the automatic extraction of 8 codicological parameters: Filling coefficient, percentage of ink on the entire page, percentage of ink in the written area, number of rows, line spacing, text height, page size, and page ratio. This study shows the evolution of these 8 parameters over the centuries, and finally a first neural network capable of automatically dating Western medieval manuscripts has been built.

The proliferation of deepfakes—AI-generated or manipulated media—has transformed the landscape of contemporary art. Deep generative models, including GANs, VAEs, diffusion models, and Transformers, have enabled artists to explore new creative realms while simultaneously raising critical questions around authenticity, ethics, and detection. This paper presents a comprehensive analysis of deepfake technologies across five key media modalities: image, video, text, speech, and music. We examine the architectures that enable content creation, and the state-of-the-art techniques used for detection. Further, we evaluate detection accuracy, robustness, and practical implementation, incorporating diagrams, comparative tables, and performance formulas. This work aims to provide a balanced perspective on the opportunities and challenges posed by synthetic media in the artistic domain.

Digitalization of the cultural heritage can be considered from multiple perspectives. In this work, we present a case study based on the ancient city of Karkemish to propose a structured pipeline for developing an Artificial Intelligence (AI)-assisted Virtual Reality (VR) system. The framework outlines a roadmap for creating a user-friendly and gamified VR interface, incorporating qualitative and quantitative evaluation methods before deployment. Qualitative assessments focus on User Interface/User Experience (UI/UX) design, while quantitative evaluations utilize electroencephalogram (EEG) data to monitor cognitive and emotional responses, aiming to promote a positive user experience. Moreover, we introduce a privacy-preserving approach to ensure the user's privacy during the system interaction. The study’s aim is twofold: a) preservation and dissemination of endangered cultural heritages, and b) improving the quality of life for individuals with limited mobility (handicapped, elderly, heritage site restrictions, poverty) by enabling virtual access to cultural heritages.

This study re-evaluates the manuscript corpus attributed to the Serbian copyist Damijan-Iosif through the application of the Cyrillic Palaeography Toolkit, a digital instrument enabling detailed script analysis. By reassessing six manuscripts bearing his name or monogram and examining two additional codices previously linked to an anonymous collaborator, the study attributes them all to Damijan-Iosif. A further manuscript reveals the presence of a collaborator, distinguished through palaeographic and layout features. These findings shed new light on collaborative practices within the Hilandar scriptorium and demonstrate the potential of digital methodologies to enhance traditional palaeographic attribution frameworks in South Slavonic manuscript studies.

Open Science (OS) is a global movement that transforms the way research is conducted, shared, and utilised by promoting transparency, accessibility, and collaboration. Bulgaria has embraced these principles by implementing policies and practices aligned with European frameworks to facilitate Open Access, FAIR (Findable, Accessible, Interoperable, and Reusable) data management, and collaborative research infrastructures. As a member of the European Open Science Cloud Steering Board, Bulgaria showcases its commitment to building a European ecosystem for OS. It urges national research communities to engage in European initiatives such as Openaire, NI4OS-Europe and Skills4eosc. These initiatives seek to establish the foundations of OS by sharing scientific knowledge products (research articles, data, and software) and actively participating in the process of knowledge production (citizen science, crowdsourcing). This paper presents Bulgaria's participation in the Skills4EOSC project, the benefits of the project for advancing Open Science in Bulgaria, and its contribution to the country's integration into the European Research Area.
