Invasive coronary studies are confined to symptomatic patients and therefore may suffer from a selection bias. Nevertheless, there appears to be good correlation between coronary and peripheral artery endothelial function in the same subjects [51]. Furthermore, no longitudinal studies in humans have ...
Why is it that "high energy" waves have high frequencies and amplitude doesn't affect speed, but at the same time the amplitude of a wave is proportional to the energy of a wave? How is the frequency of a transverse wave determined? What is the frequency of an electromagnetic wave if ...

How can the speed of a mechanical wave be calculated?How do transverse waves move?Why is it that "high energy" waves have high frequencies and amplitude doesn't affect speed, but at the same time the amplitude of a wave is proportional to the energy of a wave?
Since sound is a wave, it has all of the properties attributed to any wave, and these attributes are the four elements that define any and all sounds. They are the frequency, amplitude, wave form and duration, or in musical terms, pitch, dynamic, timbre (tone color), and duration. What...
The shape, frequency and amplitude of the waveforms provide information about the stage and intensity of sleep. MURAMYL PEPTIDES Fragments of peptidoglycans, from the cell walls of Gram-positive bacteria, that are thought to have a crucial role in the generation of the immune response to Gram-...
Intact stabilityand its designated parameters have a great role to play in terms of seakeeping. The more inherently stable the ship is, both in a longitudinal and transverse sense, the higher its seakeeping characteristics. However, caveats are there. We all have heard of “stiff” and “tender...
Sound moves as a longitudinal wave.That means the molecules will move outward with the shockwave, but they will return to their starting position afterward. There is no net movement of the molecules — that’s why sound doesn’t cause wind. ...
How do longitudinal sound waves work? Which can travel in outer space: sound waves or EM waves? Explain you answer. What waves cause back and forth motion? If you increase the frequency of a sound wave four times, what will happen to its speed? What is refraction of sound? What happens...
To reinforce our assessment, we compare the mean speckle size generated by structured light modes with that generated by wave fronts of constant phase and amplitude and show that in both cases the mean speckle size is almost identical. Our findings reveal a fundamental property of speckle, which...
