There is an optical diffraction limit for the recording density of conventional optical recording systems. There has been a lot of recent interest in the field of optical storage technologies for the recording methods that are based on near-field optical principles because they have the potential to overcome the limitation by using the localized optical near-field for writing and reading recorded...
Background: Pulse wave velocity (PWV) and ankle-brachial blood pressure index (ABPI) are markers for atherosclerosis, and each predicts mortality in patients undergoing hemodialysis. However, there have been no studies in the past that compared head-to-head the clinical validity of these 2 parameters. Compared with conventional aortic PWV, brachial-ankle PWV (baPWV) is considered simple and thereby...
