Interestingly, one observes that higher harmonic contributions always lead to a deformation of the acoustic wave, such that the leading edge has a steeper slope than the trailing edge. This phenomenon is known as wave steepening and constitutes a well documented non-linear phenomenon [46]. 3.5....
A longitudinal view of the maximal pressure for a monochromatic acoustic field radiated at 0.5 MHz by the 25.40-mm-Ø, 31.75-mm-focus transducer (top). The maximum pressure is reached at 25.9 mm, slightly closer to the transducer than the geometric focal point, which is a ...
A The wave is longitudinal and has a period of 25 ms. B The wave is longitudinal and has a frequency of 50 Hz. C The wave is transverse and has an amplitude of 3 µm. D The wave is transverse and has a wavelength of 20 ms. 23 A cathode-ray oscilloscope (CRO) is used to ...
with the criminal justice system.OBJECTIVE To report national estimates of adolescent sexual violence perpetration and details of the perpetrator experience.DESIGN, SETTING, AND PARTICIPANTS Data were collected online in 2010 (wave 4) and 2011 (wave 5) in the national Growing Up With Media study. ...
Subgrid momentum fluxes are not predicted, but this is not expected to strongly affect the results since we do not have topography that could generate strong gravity wave drag and since tropical convection occurs in regions of relatively weak shear in our simulations. We assume that the subgrid...
When qy≡ 0 (qx≡ 0), the wavevector of the perturbation is parallel (perpendicular) to the wavevector of the roll pattern. The corresponding mode is called longitudinal (transverse). Sign in to download full-size image Fig. 1. Level curves of s(+)(qx,qy;δk): a) for δk = ...
Tested on 4 experimental designs (case-control, longitudinal, irregular block design, scRNA and snRNA integration). Outperforms Seurat, Harmony, LIGER, Symphony integration, as judged by local inverse Simpson’s index (LISI). Python implementation. Paper Zhang, Zhaojun, Divij Mathew, Tristan Lim...
The structure of the data requires the use of structural equation (SEM) methods combining longitudinal, multi-level, path analytic models with confirmatory factor analysis. The psychometric properties of the outcome variables, including measurement invariance between time points T1, T2, and T3, are te...
Longitudinal studies have determined the possible influence of the quarantine period associated with the COVID-19 pandemic on sleep quality in the adult population [50,51]. Alfonsi et al. reported higher scores on sleep latency, sleep efficiency, and medication use components during quarantine, ...
The 𝑋𝑏𝑂𝑏𝑌𝑏XbObYb represents the horizontal ship body-fixed coordinate system. 𝐺G is the center of ship gravity, 𝑢u is longitudinal velocity, 𝑣v is lateral velocity, 𝛿δ is yaw angle, and 𝑟r is the yaw angular velocity. Thus, the horizontal plane motion ...
