Mechanical pathophysiology of some heart diseases: a theoretical model studyMedical & Biological Engineering & Computing - Tập 28 - Trang 237-248 - 1990
R. Beyar, S. Sideman
Sarcomere dynamics are related to the global left ventricular (LV) function in some representative pathological states, by using a theoretical model which combines sarcomere function, LV fibrous structure and geometry with the haemodynamic loading conditions. The analysis shows that pressure (concentric) hypertrophy due to hypertension or aortic stenosis is associated with an increase of the norma...... hiện toàn bộ
An extensometer for skin—Its construction and applicationMedical & Biological Engineering & Computing - Tập 4 - Trang 533-542 - 1966
M. D. Ridge, V. Wright
For the investigation of the rheological properties of human skin an extensometer has been constructed which is capable of extending specimens at a constant rate under controlled temperature and humidity, recording the results in the form of a stress-strain curve. Sections of the curve have been attributed to various phases of extension. Empirical equations have been fitted to these phases of exte...... hiện toàn bộ
Cellular automation model of ventricular conductionMedical & Biological Engineering & Computing - Tập 30 - Trang 481-486 - 1992
R. H. Mitchell, A. H. Bailie, J. McC Anderson
A computer simulation of ventricular conduction is presented with a discrete element ventricular conduction model. The model is shown to be capable of demonstrating normal ventricular rhythm, including QRS and T-waves, plus a variety of rhythm disturbances including missed beats, electrical alternans and self-sustaining instability with arrythmias. The morphology of the range of alternans produced...... hiện toàn bộ
Fluorescence microscopy image classification of 2D HeLa cells based on the CapsNet neural networkMedical & Biological Engineering & Computing - - 2019
XiaoQing Zhang, Shu-Guang Zhao
The development of computer technology now allows the quick and efficient automatic fluorescence microscopy generation of a large number of images of proteins in specific subcellular compartments using fluorescence microscopy. Digital image processing and pattern recognition technology can easily classify these images, identify the subcellular location of proteins, and subsequently carry out relat...... hiện toàn bộ
