Slow phase velocity
Webb13 sep. 2004 · The nystagmus intensity is defined as the slow-phase velocity (SPV). To measure SPV for one nystagmus beat, the examiner has to determine the distance that … WebbThe phase velocity is: vp = ω/k . The function ω(k), which gives ω as a function of k, is known as the dispersion relation . If ω is directly proportional to k, then the group …

WebbFör 1 dag sedan · The slow phase velocity approximates stimulus velocity. The second response corresponds to a slower buildup of stored neuronal activity. The neural pathway controlling OKN involves the cortex, brainstem, and cerebellum. 2-5 Anatomical pathways of the OKN are known from animal studies, lesions in humans and, recently, by … Webb23 maj 2024 · Each of the subjects with peripheral vestibular lesions generated an appropriately directed horizontal nystagmus after head shaking that then suppressed the induced angular slow phase velocity on average 52 ± 17.6% following tilt down of the head.
Webb27 sep. 2024 · reduced are patients with fast phase disorders. The most common clinical disorder of this type is a degenerative disorder of the brainstem called progressive supranuclear palsy (PSP), in which saccades are slowed and difficult to initiate. Accordingly, patients with PSP may have normal pursuit to a sinusoid or triangular WebbCircular synthetic aperture radar (CSAR), which can observe the region of interest for a long time and from multiple angles, offers the opportunity for moving-target detection (MTD). However, traditional MTD methods cannot effectively solve the problem of high probability of false alarm (PFA) caused by strong clutter. To mitigate this, a novel, three-step …
WebbPerformance for a runner can be represented by the relation of his/her personal power (velocity) to time to exhaustion (time limit).1 There are particular velocities that delineate intensity domains which are determined by oxygen uptake (V̇o2) and blood lactate response versus time.2,3 We are going to use them to define the slow phase of V̇o2 …
