Journal ArticleDOI
An optical coherence tomography (OCT)-based air jet indentation system for measuring the mechanical properties of soft tissues.
TL;DR: A novel noncontact indentation system with the combination of an air jet and optical coherence tomography (OCT) was presented in this paper for the quantitative measurement of the mechanical properties of soft tissues.
Journal ArticleDOI
Estimating the effective Young's modulus of soft tissues from indentation tests--nonlinear finite element analysis of effects of friction and large deformation.
TL;DR: It is found that the factor kappa increases almost proportionally to the increase of the indentation depth, especially obvious with a larger Poisson's ratio v and a larger aspect ratio a/h.
Journal ArticleDOI
An ultrasound indentation system for biomechanical properties assessment of soft tissues in-vivo
Yongping Zheng,Arthur F.T. Mak +1 more
TL;DR: An ultrasound indentation system for biomechanical assessment of soft tissues in vivo was developed and the specific application is for stump tissue assessment in the design of prosthetics.
Journal ArticleDOI

TL;DR: The role of lysyl oxidase‐like 2 (LOXL‐2) in the biology of HCC metastasis is investigated, finding not only that LOXL2 was regulated by hypoxia/hypoxia‐inducible factor 1 alpha (HIF‐1α), but also that TGF‐β activated LOXL 2 transcription through mothers against decapentaplegic homolog 4 (Smad4).
Journal ArticleDOI
Review / Sythèse Nonlinear acoustic applications for material characterization: A review
TL;DR: In this paper, the effects of nonlinearity, dissipation, dispersion, and diffraction on material characterization applications are reviewed and the general theoretical analysis of these effects is presented.
