Confounding factors in ultrasound liver elastography. Part 2. Distortion of measurement results due to the characteristics of the state of the body and external influences [PDF]
Вестник Витебского государственного медицинского университета, 2023 The purpose of the study was to analyze the external influences and characteristics of the state of the organism being examined, which affect the results of ultrasonic elastography of the liver. Internal confounding factors include: inflammation and some

Journal of Hand and Microsurgery, 2015 Background Finger stiffness varies substantially in patients with hand and upper extremity illness and can be notably more than expected for a given pathophysiology. In prior studies, pain intensity and magnitude of disability consistently correlate with coping strategies such as catastrophic thinking and kinesiophobia, which can be characterized as ...

Physical Review E, 2007 We report on the geometry and mechanics of knotted stiff strings. We discuss both closed and open knots. Our two main results are: (i) Their equilibrium energy as well as the equilibrium tension for open knots depend on the type of knot as the square of the bridge number; (ii) Braid localization is found to be a general feature of stiff strings ...

Stiffness Modeling and Dynamics Co-Modeling for Space Cable-Driven Linkage Continuous Manipulators
Mathematics, 2023 The space cable-driven continuous manipulator (SCCM) has a slender structure, ultra-high degrees of freedom, and a low mass, which make it suitable for equipment inspection and maintenance operations in an unstructured and limited space environment.
