Due to the UN and EU’s strong interest in digitizing cultural heritage, the application of 3D scanning technology is gaining importance, even in the case of under-explored areas, such as the 3D scanning of historical clothes. This article discovers and compares methodologies of 3D scanning of historical clothes presented in the literature in order to determine if a new methodology is needed. PRISMA protocol was used to browse scientific sources in an organized way. We posed the following research question: How have 3D scanners been used to digitize historical clothes? The very limited number of works identified, despite our thorough search, allows us to conclude that this topic is very new, and a lot of research can be conducted in the future. We analyzed the methodologies proposed by other authors, taking into account factors such as what was scanned, what was the purpose of scanning, what hardware and software was used, how detailed the description was, etc. It was revealed that other authors explored the topic insufficiently and no complex and coherent methodology of 3D digitization of historical clothes is present. Generally, the field of 3D scanning of historical clothing remains, at this point, very small and fragmented. This work is one of steps to change it.

The development of information technology (IT) now allows for rapid, semi-automatic digitization of cultural heritage objects, both typical museum exhibits and architectural monuments. However, the same IT development makes it possible to disseminate the results of digitization, i.e., to reach a wide audience. This article presents the methodology of 3D scanning and processing of the acquired data on the surface condition of large architectural objects to develop their models and make various variants of their visualization. The developed methodology was divided into many stages and steps. It provides methods, techniques, and recommendations on how to solve specific problems that interfere with the process of data acquisition under typical conditions of continuous access to the objects by tourists and the impossibility of turning the object off from the visitors. The methodology prepared was used and tested during field trips to Kazakhstan and Uzbekistan in 2018--2019 to prepare digital visualizations of objects belonging to the group of monuments called Timurid architecture. Preparation and in situ verification of 3D data acquisition procedures under different traditions, cultures, religions, customs, administrative procedures, time constraints, technical resources, and climatic conditions is of great importance for effectively equipping research expeditions dealing with the digitization of architecture in different areas of the world.

Three dimensional digitization of cultural heritage resources gains a lot of attention from the European Union and the United Nations, which is clearly revealed in current strategic goals and financing perspectives. Existing methodological approaches to 3D scanning in a prevailing number of cases assume that the procedure of scanning is performed in places that are closed to tourists, at least for the time of scanning. However, closing an exhibition for tourists or moving an artifact to be scanned is not always possible. Thanks to the long-term experience of the authors with 3D scanning of cultural heritage, the special procedure was designed for small and medium size objects to overcome difficulties expected in such cases. The procedure has been successfully implemented during 3D scanning of objects exhibited in the Silk Road region (on the territory of modern Uzbekistan), as well as objects being parts of wooden sacral architecture of the Maramures region (in Romania). It was revealed that the proposed procedure was successfully allowed to counteract organizational problems during 3D scanning of heritage objects being under continuous display, and that the achieved results of scanning were nevertheless of good quality.

In the rapidly evolving field of multi-omics data analysis, understanding the stability of feature selection is critical for reliable biomarker discovery and clinical applications. This study investigates the stability of feature-selection methods across various cancer types by utilizing 15 datasets from The Cancer Genome Atlas (TCGA). We employed classifiers with embedded feature selection, including Support Vector Machines (SVM), Logistic Regression (LR), and Lasso regression, each incorporating L1 regularization. Through a comprehensive evaluation using five-fold cross-validation, we measured feature-selection stability and assessed the accuracy of predictions regarding TP53 mutations, a known indicator of poor clinical outcomes in cancer patients. All three classifiers demonstrated optimal feature-selection stability, measured by the Nogueira metric, with higher regularization (fewer selected features), while lower regularization generally resulted in decreased stability across all omics layers. Our findings indicate differences in feature stability across the various omics layers; mirna consistently exhibited the highest stability across classifiers, while the mutation and rna layers were generally less stable, particularly with lower regularization. This work highlights the importance of careful feature selection and validation in high-dimensional datasets to enhance the robustness and reliability of multi-omics analyses.

People with visual impairment are excluded from experiencing the cultural heritage presented by museums in a traditional manner. To enable them to touch the museum exhibits, a set of touchable copies needs to be made. The article presents the use of latest computer graphics technologies, such as 3D scanning, postprocessing and 3D printing, in improving such an enterprise. The current state of research is discussed both in the technical and organisational aspect of preparing "tactile expositions". This is followed by a step-by-step description of preparing touchable museum objects, with a discussion of the possible use of 3D technologies to aid this task. Attention is also paid to issues connected with engineering education of students. The authors think that the problem of creating objects accessible to the blind is socially useful and will encourage students to be active in this area. Finally, a genuine museum object is described as an illustration of preparing a touchable exhibit, clearly showing the advantages of using 3D technologies to this end.
