陕西及邻区瑞雷波相速度层析成像

open access: yesDizhen xuebao, 2019
本文利用布设于陕西及其邻区的喜马拉雅二期流动地震台阵和区内的固定地震台网共计257个台站于2014—2015年记录到的连续波形资料,采用基于图像分析的相速度提取方法,得到了7 185条瑞雷波相速度频散曲线,反演获得了周期为5—40 s的瑞雷波相速度分布图像,其最小分辨率约为20 km。结果表明:各周期瑞雷波相速度图像具有明显的横向不均匀性,能够较好地反映出地壳及上地幔顶部的地质构造特征。周期为5—10 s的瑞雷波相速度分布与地表地质构造密切相关,且高低速异常的分界线与地块边界高度吻合;周期为15 ...

The Repolarization Phase of the Spatial Velocity Electrocardiogram

open access: yesJapanese Circulation Journal, 1968
The repolarization complex of the spatial velocity electrocardiogram was studied in 502 cases. Normal repolarization was composed of two main deflections, τ1 and τ2, and τ1 was smaller than τ2. Most typically in left ventricular hypertrophy and in left bundle branch block τ1 was smaller and τ2 Was larger than in the normal state.

Wave propagation in a hygrothermoelastic half-space along with non-local variable

open access: yesJournal of Applied Science and Engineering
This particular work is an effort to investigate the propagation of wave in hygrothermoelastic medium in the light of Eringen’s nonlocal theory of elasticity. The coupled wave equations in terms of displacement, temperature and moisture concentration are

Acoustoelectric Effect for Rayleigh Wave in ZnO Produced by an Inhomogeneous In-Depth Electrical Conductivity Profile

open access: yesSensors, 2023
The acousto-electric (AE) effect associated with the propagation of the Rayleigh wave in ZnO half-space was theoretically investigated by studying the changes in wave velocity and propagation loss induced by in-depth inhomogeneous changes in the ZnO ...

Solving the Christoffel equation: Phase and group velocities [PDF]

open access: yesComputer Physics Communications, 2016
Abstract We provide christoffel , a Python tool for calculating direction-dependent phase velocities, polarization vectors, group velocities, power flow angles and enhancement factors based on the stiffness tensor of a solid. It is built in a modular way to allow for efficient and flexible calculations, and the freedom to select and combine results ...

Effectiveness of Resistance Intradialytic Exercise Compared to Aerobic Intradialytic Exercise for Patients With Chronic Kidney Disease: A Randomized Controlled Clinical Trial

open access: yesTherapeutic Apheresis and Dialysis, EarlyView.
ABSTRACT Background Patients with chronic kidney disease undergoing hemodialysis commonly experience reduced physical function, fatigue, poor sleep quality, and impaired health‐related quality of life. Intradialytic exercise has been proposed as a non‐pharmacological strategy to improve these outcomes.

Serum Myonectin Levels Are Positively Associated With Physical Function and Lower Frailty‐Related Limitation in Maintenance Hemodialysis Patients: A Cross‐Sectional Study

open access: yesTherapeutic Apheresis and Dialysis, EarlyView.
ABSTRACT Background Maintenance hemodialysis (MHD) patients frequently suffer from frailty, characterized by reduced physical function and poor prognosis. Myokines, such as myonectin, secreted by muscle, are emerging regulators of systemic health. This study investigated the relationship between serum myonectin, adipokines (adiponectin, omentin), and ...
