Modifying exercise and physical therapy in medical rehabilitation to promote a physically active lifestyle: Protocol for a multicenter controlled hybrid type 2 effectiveness-implem...
Published 2025-05-01“…Abstract Introduction Since rehabilitation programs often do not enhance long-term physical activity in persons with a health condition, there is a great need to arrange rehabilitation concepts towards a stronger emphasis on sustainable physical activity promotion. In this regard, the model of physical activity-related health competence (PAHCO) offers the potential for optimizing physical activity promotion. …”

Comparative analysis of the effectiveness of BPG, AGU, AVIF and HEIF compression methods for medical images corrupted by noise of two types
Published 2025-05-01“…The scientific novelty of the obtained results includes: 1) The consideration of noise models and parameter levels typical for medical imaging, namely, additive Gaussian noise of such intensity that it approximately corresponds to just noticeable differences, and signal-dependent Poisson noise; 2) The analysis of the multi-scale structural similarity index (MS-SSIM), which has not been previously explored in studies on lossy compression of noisy medical images; 3) A detailed examination of AVIF and HEIF coders to determine whether the optimal operating point (OOP) is observed for them and under which noise conditions; 4) The use of a dataset comprising ten medical images of varying visual complexity, with generalized tendencies revealed for different structural types; 5) The identification of the ability of many metrics to exhibit an OOP for images of moderate visual complexity or those dominated by homogeneous areas; 6) For Poisson noise, the demonstration of a dependence between the quality factor Q in the OOP and the average image intensity, which can be practically estimated for a given image; 7) The finding that different encoders require different approaches to determine their respective OOPs due to their distinct compression control parameters; 8) The observation that compression ratios achieved at the OOP are generally high, supporting the feasibility of using the OOP or its neighbourhood in practice.…”
