An Initial Residual Stress Inference Method by Incorporating Monitoring Data and Mechanism Model
Chinese Journal of Mechanical Engineering, 2022 Initial residual stress is the main reason causing machining deformation of the workpiece, which has been deemed as one of the most important aspects of machining quality issues.

Microfluidic Adaptation of Density-Gradient Centrifugation for Isolation of Particles and Cells
Bioengineering, 2017 Density-gradient centrifugation is a label-free approach that has been extensively used for cell separations. Though elegant, this process is time-consuming (>30 min), subjects cells to high levels of stress (>350 g) and relies on user skill to ...

A micromorphic approach to stress gradient elasticity theory with an assessment of the boundary conditions and size effects [PDF]
ZAMM - Journal of Applied Mathematics and Mechanics / Zeitschrift für Angewandte Mathematik und Mechanik, 2018 AbstractBasing on thermodynamics principles, a stress gradient elasticity theory is presented whereby the material is modeled as a centro‐symmetric micromorphic anisotropic material. A principle of minimum complementary energy and a stationarity principle of Hellinger–Reissner type are provided, by which the boundary conditions are uniquely determined ...

Distribution of material properties in finite element models of inhomogeneous elements of structures [PDF]
EPJ Web of Conferences, 2019 This paper discusses an approach to finite element modelling of structure elements considering material inhomogeneity. This approach is based on the functional dependence of mechanical properties on the spatial coordinates of finite elements.

Natural Killer Cells in Paediatric Soft Tissue Sarcomas: A Systematic Review
Pediatric Blood &Cancer, EarlyView.ABSTRACT Paediatric soft tissue sarcomas (pSTS) are a rare and heterogeneous group of malignant tumours arising in tissues of mesenchymal origin. The role of natural killer (NK) cells in pSTS remains poorly understood, with evidence fragmented across small preclinical studies and early‐phase clinical trials.
