Joint Stiffness Identification of a Heavy Kuka Robot with a Low-cost Clamped End-effector Procedure [PDF]
, 2014 This paper proposes two new methods for the identification of static stiffnesses of multi degrees of freedom heavy industrial robots. They are based on a locked link joint procedure obtained with an end-effector fixed to the environment. The first method

Effect of matrix stiffness on osteoblast functionalization [PDF]
Cell Proliferation, 2017 AbstractObjectivesStiffness of bone tissue differs response to its physiological or pathological status, such as osteoporosis or osteosclerosis. Consequently, the function of cells residing in bone tissue including osteoblasts (OBs), osteoclasts and osteocytes will be affected.

Frontiers in Physiology, 2022 The activation of Yes-associated protein (YAP) pathway is mutually causal with the increase of extracellular matrix (ECM) stiffness. Polydatin (PD) has been proved to have anti-fibrosis effect in diabetic kidney disease (DKD), but it is still a mystery ...

Matrix Stiffness and Colorectal Cancer.
OncoTargets and therapy, 2020 In recent years, a growing consensus is emerging that the mechanical microenvironment of tumors is far more critical in the onset of tumor, tumor progression, invasion, and metastasis. Matrix stiffness, one of the sources of mechanical stimulation, affects tumor cells as well as non-tumor cells in multiple different molecular signaling pathways in ...

TRPV4 Plays a Role in Matrix Stiffness-Induced Macrophage Polarization
Frontiers in Immunology, 2020 Phenotypic polarization of macrophages is deemed essential in innate immunity and various pathophysiological conditions. We have now determined key aspects of the molecular mechanism by which mechanical cues regulate macrophage polarization. We show that
