Characterization of soil stiffness anisotropy at small strains based on phase velocities of shear waves measured by novel testing apparatus [PDF]
E3S Web of ConferencesFor the characterization of soil stiffness anisotropy at small strains and the calculation of soil elastic constants derived from the cross-anisotropic model, it is important to obtain stress wave phase velocities of soils in both principal and oblique ...

A Monte-Carlo error analysis for basal sliding velocity calculations [PDF]
, 2006 Since glacier beds are mostly inaccessible, numerical inversion of the surface velocity field provides a valuable method for calculating the basal shear stress and sliding velocity. However, previous theoretical studies (limited either to planar slabs or

Dizhen 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
Japanese 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.

FEBS Letters, EarlyView.Fluorescent probes allow dynamic visualization of phosphoinositides in living cells (left), whereas mass spectrometry provides high‐sensitivity, isomer‐resolved quantitation (right). Their synergistic use captures complementary aspects of lipid signaling. This review illustrates how these approaches reveal the spatiotemporal regulation and quantitative

Wave propagation in a hygrothermoelastic half-space along with non-local variable
Journal of Applied Science and EngineeringThis 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

FEBS Letters, EarlyView.The Ile181Asn variant of human UDP‐xylose synthase (hUXS1), associated with a short‐stature genetic syndrome, has previously been reported as inactive. Our findings demonstrate that Ile181Asn‐hUXS1 retains catalytic activity similar to the wild‐type but exhibits reduced stability, a looser oligomeric state, and an increased tendency to precipitate ...
