Pulse: Revived in ‘The Pulse of Asia’
Blood flow in arteries is pulsatile, and palpating arterial pulse has a long history and is full of brilliant surprises. The finding that very ancient physicians applied this technique when diagnosing and treating sick people dates back to 600 BC in Eastern countries. It is thought that arterial pulse was first mentioned in the ‘Classic of Internal Medicine’ Nei Ching written by the Yellow Empe...
متن کاملExtending the Radar Dynamic Range using Adaptive Pulse Compression
The matched filter in the radar receiver is only adapted to the transmitted signal version and its output will be wasted due to non-matching with the received signal from the environment. The sidelobes amplitude of the matched filter output in pulse compression radars are dependent on the transmitted coded waveforms that extended as much as the length of the code on both sides of the target loc...
متن کاملInter-pulse Interval Affects the Size of Single-pulse TMS-induced Motor Evoked Potentials: a Reliability Study
Introduction: Measuring the size of motor evoked potentials (MEPs) induced by transcranial magnetic stimulation (TMS) is an investigational technique to show the level of corticospinal excitability however, some of the fundamental methodological aspects of TMS (such as the effects of inter-pulse intervals (IPI) on MEP size) are not fully understood, this issue raises concerns about the re...
متن کاملArbitrary Pulse Width in the Four-Pulse NMR Experiment
The classical four-pulse experiment as invented by W A U G H , H U B E R , and H Ä B E R L E N 2 has been proven to be very effective in reducing the dipolar broadening in the nmr spectra of solids and unravelling weaker interactions such as magnetic shielding anisotropics, /-coupling etc. 3. There is a considerable amount of other types of line narrowing experiments which are capable of reduci...
متن کاملOn checking the pulse.
From the earliest of times physicians have been taught to evaluate the character of the pulse as an essential feature of the physical examination. This recommendation was based entirely on clinical impression; only recently has rigorous scientific evidence been provided in support of this ‘vital sign’. Now, in addition to the resting heart rate, heart rate variability and the heart rate respons...
