By combining time-frequency analysis with a broadband acoustic excitation source, the dispersion of multiple Lamb modes over a wide frequency range can be determined from as little as a single measurement. In addition, the technique provides a direct measurement of the group velocity dispersion. The...
Because of the unique tectonic, sedimentary background of the region, velocity model building and time-depth conversion have been an important and difficult problem for a long time. Recent researches in this direction have revealed three major problems for deepwater areas, i.e., the way to ...
Implementing the feedback of your users is a logical first step to optimize your analytics solution. There may also be opportunities to remove latency in the process, for example, ensuring the data refresh occurs in the allotted time. Optimization could also mean more accurately refle...
terminal velocity- the constant maximum velocity reached by a body falling through the atmosphere under the attraction of gravity rate- a magnitude or frequency relative to a time unit; "they traveled at a rate of 55 miles per hour"; "the rate of change was faster than expected" ...
When the observed pattern of solar magnetic fields is decomposed in its spherical-harmonic components and a time series analysis is performed, a resonant g... JO Stenflo - 《Astrophysics & Space Science》 被引量: 45发表: 1988年 A constrained-mode analysis of the fluidelastic instability of a...
To infer the differentiation trajectories of B cells in MIBC, we performed RNA velocity analysis. This analysis predicted that plasma-MZB1, plasma-IGHG1, plasma-IGHA1 and plasma-IGHG2 likely originate from proliferative B cells (B-STMN1) and that B-IL4R subtype cells could develop into B-...
The size of the points is proportional to the p.d.f of the time spent at each distance. Full size image Figure 15 Scatter plot of the average angle between the velocity of the players and their distance to the ball vector at (a) attacking and (b) defending phases. Goalkeepers (blue)...
笔者综合前人资料和遥感影像特征认为,区域上比较典型的穿越重要城市圈、活动性较为显著且对区域地壳稳定性可能具有显著影响的北东向断裂主要分布在渝东—鄂西山地、江汉—洞庭湖盆地周边和皖江河谷等区域。 4.1.1 渝东—鄂西山地的主要活动断裂 渝东—鄂西山地最显著且最具代表性的活动断裂是黔江—建始断裂带(又称黔江...
Two-dimensional Laplace-domain waveform inversion using adaptive meshes: an experience of the 2004 BP velocity-analysis benchmark data set To delineate the Earth's structure precisely by time- or frequency-domain waveform inversions, an appropriate initial model that contains long-wavelength s... CY...
Branch expression analysis modeling (BEAM) was used to analyze the pseudo-time-dependent or branch-dependent genes. The genes that were significantly branch-dependent were visualized by the “plot_genes_branched_heatmap” function. RNA velocity analysis...
