Because systole and diastole are coupled and systolic ventricular-vascular coupling has been characterized, we hypothesize that diastolic ventricular-vascular coupling (DVVC) exists and can be characterized in terms of relaxation and stiffness. To characterize and elucidate DVVC mechanisms, we introduce time derivative of pressure (dP/dt) vs. time-varying pressure [P(t)] (pressure phase plane, ...

The design of intersecting nodes in high-rise oblique mesh structures is a critical issue. existing research on the meshes mainly focuses plane and monotonic axial compression loads. cannot consider contribution node’s out-of-plane angle floor beam to stiffness actual structures. In this paper, numerical analysis using ABAQUS was conducted investigate mechanical performance space (OMSIN) under ...

An incremental Contour Method (iCM) of residual stress measurement is proposed where stresses in the body interest are sequentially reduced by successive contour cuts and risk re-distribution plasticity mitigated or eliminated. The cutting-induced known to cause significant inaccuracies when trying measure near-yield using a conventional single cut method. iCM procedure implements new displacem...

In all media in which the elastic stiffness tensor and density vary in space, an implicit, frequency-dependent anisotropy is present, even if the medium is locally isotropic. This predicts a non-linear, frequency-dependent polarization of body waves, and explains shear-wave splitting in heterogeneous media. Examples are presented for compressional and shear waves in a medium in which the elasti...

In this paper, the seismic performance of reinforced concrete moment-resisting frame with cold-joint subjected to monotonic lateral load has been studied numerically using Pushover analysis. Two modes fracture may occur for in a in-plane loading. The are Mode-I (stress orthogonal local plane crack surface) and Mode-II parallel surface but front). order model verify its behavior mode I II mechan...

Using videomicroscopy imaging, we demonstrate the existence of a short-ranged equilibrium attraction between heavy silica colloids diffusing on soft surfaces of cross-linked polymer gels. The intercolloid potential can be tuned by changing the gel stiffness or by coating the colloids with a polymer layer. On sufficiently soft substrates, the interaction induced by the polymer matrix leads to la...

The results of immediate plate fixation of 97 open fractures of the tibial shaft in 95 patients are reported. Significant joint stiffness occurred in 11.4% and angular malunion of greater than 5 degrees in any plane was seen in 3.1%. The infection rate was 10.3%. However, even in those cases which develop delayed union or other complications, plate fixation of open fractures can produce excelle...

Skeletal muscle weakness is frequently associated with stiffness changes [1,2], which may alter functional contraction and passive elongation dynamics. Cine Phase Contrast (CPC) MRI has been successfully used to quantify skeletal muscle strain distribution in a single plane [3,4]. The strain distribution was found to be non-uniform, indicating complex internal dynamics of skeletal muscle. The o...

Abstract Based on the couple-stress theory, elastohydrodynamic lubrication (EHL) contact is analyzed with a consideration of size effect. The lubricant between surface homogeneous coated half-plane and rigid punch supposed to be non-Newtonian fluid. density viscosity are dependent fluid pressure. Distributions film thickness, in-plane stress, pressure calculated by solving nonlinear fluid-solid...

Background : Aortic stiffness, an independent predictor of mortality and cardiovascular events, is common among patients affected by non-ischemic dilated cardiomyopathy (NIDC) and heart failure (HF). Methods : A total of 55 patients with diagnosis of NIDC (aged 60 ± 11 years, mean ejection fraction (EF) 35.2% ± 7.7%) admitted consecutively to our department for mild to moderate HF (NYHA class...
