    Longitudinal assessment of changes in muscle composition using proton density fat fraction and T2* in patients with and without incidental vertebral compression fractures by Yannick Stohldreier, Yannik Leonhardt, Jannik Ketschau, Florian T. Gassert, Marcus R. Makowski, Jan S. Kirschke, Georg C. Feuerriegel, Philipp Braun, Benedikt J. Schwaiger, Dimitrios C. Karampinos, Nina Hesse, Alexandra S. Gersing, Alexandra S. Gersing

    Published 2025-03-01
    “…ObjectiveChemical shift encoded-based water-fat separation magnetic resonance imaging (CSE-MRI) is an emerging noninvasive tool for the assessment of bone and muscle composition. This study aims to examine both the predictive value and the longitudinal change of proton density fat fraction (PDFF) and T2* in the paraspinal muscles (PSM) in patients with and without the development of an incidental vertebral compression fracture (VCFs) after 6 months of follow-up.MethodsPatients (N=56) with CT and 3T CSE-MRI of the lumbar spine at baseline and CSE-MRI at 6 months follow-up were included in this retrospective study. …”

    Using Modeling and Simulation to Study the Influence of TiO2 Shape on the Dielectric Properties of TiO2/PVDF Composite by SHAN Xue-wen, YIN Jing-hua

    Published 2022-02-01
    “…By establishing two dimensional and three dimensional models, the breakdown mechanism of composite material was systematically studied from the perspectives of electric field intensity, leakage current density, and system energy density distribution, studying the influence of TiO2 shape on the dielectric performance of composite material.The results of the research show that doping 5 vol% TiO2 components, compared to the spherical TiO2/PVDF composites, the linear TiO2/PVDF composites system of electric field intensity, the leakage current density and energy density distribution is relatively uniform, the distortion of the three physical quantities is small, high electric field intensity, leakage current density and energy density area decreased significantly.On the surface of the composite, the highest electric field strength, leakage current density and energy density are reduced 1.42 times, 1.41 times, 2.01 times. …”

    Wolf Population Size and Composition in One of Europe's Strongholds, the Romanian Carpathians by Ruben Iosif, Tomaž Skrbinšek, Nándor Erős, Marjeta Konec, Barbara Boljte, Maja Jan, Barbara Promberger‐Fürpass

    Published 2025-04-01
    “…We delineated six wolf packs, with pack size varying between two and seven individuals, and documented yearly changes in pack composition. Using a spatial capture–recapture approach, we estimated population density at 2.35 wolves/100 km2 (95% BCI = 1.68–3.03) and population abundance at 70 individuals (95% BCI = 49–89). …”
