As a simple example of the "blurring" influence of noncommutative geometry, a noncommutative version of a high-frequency perturbation of a background metric is calculated. The relation between the principal null vectors of the wave and those of the induced symplectic structure is in this case particularly clear.

High frequency phonocardiography
The American Journal of Cardiology, 1961Abstract A systematic study of the high frequency components of the heart sounds and murmurs was made by means of a new standardized and calibrated phonocardiograph provided with a variable band pass filter. The frequency bands 500–1000 c.p.s. and higher were particularly studied but comparison was also made with the vibrations found in lower bands.

High-frequency ventilation (HFV) provides respiratory gas exchange using positive airway pressure-driven tidal breaths that are often smaller than anatomic dead space and breathing frequencies several times faster than normal. Gas transport with HFV involves nonconvective mechanisms such as Taylor dispersion, coaxial flow, and augmented diffusion ...

Abstract:The 1990s have seen a dramatic resurgence of interest in high frequency ventilation (HFV). The role of HFV in the rescue of infants failing conventional mechanical ventilation (CMV) is now relatively well established. However, the wider role of HFV in the routine management of respiratory failure in the newborn is more contentious.

High-frequency traders in financial markets have been making media headlines. As a relatively new phenomenon, much of the discussion is not backed by solid academic research. In this special issue of the Journal of Financial Markets on High-Frequency Trading, we present several research papers that aim to inform the discussion on this important issue.

Bioinspired Soft Magnetic Composites (SMCs) with nacre-like structure were fabricated using highly planar arranged flaky-Sendust. These SMCs show particularly high permeability and low loss, thus exhibiting great potential for high frequency magnetic ...

The adaptive market hypothesis in the high frequency cryptocurrency market
International Review of Financial Analysis, 2019This paper investigates the adaptive market hypothesis (AMH) with respect to the high frequency markets of the two largest cryptocurrencies — Bitcoin and Ethereum, versus the Euro and US Dollar.

High‐Frequency Oscillations in the Normal Human Brain
Annals of Neurology, 2018High‐frequency oscillations (HFOs) are a promising biomarker for the epileptogenic zone. It has not been possible, however, to differentiate physiological from pathological HFOs, and baseline rates of HFO occurrence vary substantially across brain ...

The current state of high frequency oscillation (HFO) in Japan is reviewed. The discussion is focused on the following: (i) the repeated application of short duration SI (sustained inflation) is effective in recruiting lung volume and increasing PaO2; (ii) HFO can prevent the formation of granulocytes related to lung injury; and (iii) HFO does not ...
