A longitudinal wave, also known as P waves, refers to waves in which the direction of propagation aligns with the direction of vibration of the medium. These waves are responsible for the intense sounds heard during major earthquakes and can travel at speeds of approximately 5 miles per second...
Longitudinal wave, wave consisting of a periodic disturbance or vibration that takes place in the same direction as the advance of the wave. A coiled spring that is compressed at one end and then released experiences a wave of compression that travels it

Longitudinal waves are the mechanical waves in which the vibration of the particles takes place in the same direction as that of the wave. Sound waves, seismic waves are the examples of longitudinal waves.
Clinically, flow-mediated vasodilation (FMD) measurements have been used as a method to assess endothelial function in populations16. The lower the FMD value is, the worse the vascular endothelial function. Brachial-ankle pulse wave velocity (baPWV) is the velocity at which a pulse wave travels ...
in the community. Unlike newly established studies which have collected exposure data during the pandemic, the long-running data collections in both LS and EHR allowed us to studyprospectiveassociations of risk factors with long COVID, meaning results will not have arisen from reverse causation, ...
23 For individuals who did not report an exact diagnosis date or for those whose dementia was ascertained with Informant Questionnaire on Cognitive Decline in the Elderly, we considered the midpoint between the wave where dementia was first ascertained and the previous wave where it was not. ...
[ 1 ], as long as the covariates have certain qualities. the covariates are required to be external, meaning their future values are known in advance and unaffected by the occurrence (or non-occurrence) of the event under study [ 2 ]. in addition, the covariates are assumed to be ...
Carbon nanotubes (CNTs) Wave propagation Magnetic field Elastic matrix 1. Introduction Since the discovery of carbon nanotubes (CNTs) in the early 1990’s by Iijima [1], the CNTs has attracted worldwide attention in many areas of science and industry and stimulated extensively experimental and the...
In addition, Fryer and Ainley (2019) found that self-efficacy and utility value consistently contributed to the maintenance of learning interest. As mentioned above, the longitudinal relation between competence beliefs and interest value might differ depending on the value components considered, meaning ...
