Analysis of striatal connectivity corresponding to striosomes and matrix in de novo Parkinson’s disease and isolated REM behavior disorder
(Nature Publishing Group, 2024)Striosomes and matrix are two compartments that comprise the striatum, each having its own distinct immunohistochemical properties, function, and connectivity. It is currently not clear whether prodromal or early manifest ... -
Short Review of the Use of Brain Morphometry in Gait Impairments Analysis in Parkinson’s Disease
(Gr. T. Popa University of Medicine and Pharmacy, 2022)With Parkinson's Disease (PD) being a neurodegenerative disease, it is necessary to understand the brain pathophysiology and its influence on the appearance of impairments in patients. One of the main fields influenced by ... -
Post-process updating of model parameters to approximate thermal errors of machine tools operating in different configurations
(Elsevier, 2024)Machine tool (MT) thermal errors induced by external and internal heat sources (e.g. changing environment, friction and power losses in MT components) are an important element in machined workpiece inaccuracies. In the ... -
CORROSION RESISTANCE AND HIGH-TEMPERATURE BEHAVIOUR OF ZR-BASED CLADDING MATERIALS WITH CHROMIUM-BASED PVD COATINGS
(European Nuclear Society, 2021)Following the Fukushima Daiichi accident, new nuclear fuel cladding designs improving the performance and enhancing nuclear power plants' safety have been extensively investigated. The chromium-based accident tolerant fuel ... -
Harmonizing Safety Perspectives: Integrating STPA outputs into MBSA for Comprehensive Aircraft Safety Assessment
