High frequency volatility co-movements in cryptocurrency markets

Journal of international financial markets, institutions, and money, 2019
Through the application of Diagonal BEKK and Asymmetric Diagonal BEKK methodologies to intra-day data for eight cryptocurrencies, this paper investigates not only conditional volatility dynamics of major cryptocurrencies, but also their volatility co ...

High-frequency dynamics of wave localisation

, 1999
We study the effect of localisation on the propagation of a pulse through a multi-mode disordered waveguide. The correlator of the transmitted wave amplitude u at two frequencies differing by delta_omega has for large delta_omega the stretched ...

A stability criterion for high-frequency oscillations [PDF]

, 2015
We show that a simple Levi compatibility condition determines stability of WKB solutions to semilinear hyperbolic initial-value problems issued from highly-oscillating initial data with large amplitudes.

High frequency homogenisation for elastic lattices [PDF]

, 2014
A complete methodology, based on a two-scale asymptotic approach, that enables the homogenisation of elastic lattices at non-zero frequencies is developed. Elastic lattices are distinguished from scalar lattices in that two or more types of coupled waves

Spatial interpolation of high-frequency monitoring data

, 2009
Climate modelers generally require meteorological information on regular grids, but monitoring stations are, in practice, sited irregularly. Thus, there is a need to produce public data records that interpolate available data to a high density grid ...

CMOS OTA-C high-frequency sinusoidal oscillators [PDF]

, 1991
Several topology families are given to implement practical CMOS sinusoidal oscillators by using operational transconductance amplifier-capacitor (OTA-C) techniques. Design techniques are proposed taking into account the CMOS OTA's dominant nonidealities.

High‐frequency oscillations: The state of clinical research

Epilepsia, 2017
Modern electroencephalographic (EEG) technology contributed to the appreciation that the EEG signal outside the classical Berger frequency band contains important information.

Cryogenic InP HEMTs With Enhanced f_max and Reduced On-Resistance Using Double Recess

IEEE Journal of the Electron Devices Society
Cryogenic InP High-electron-mobility transistors (HEMTs)-based low-noise amplifiers (LNAs) have been applied in deep space exploration, which demands high performance from InP HEMTs.
