Frontiers in Neuroscience, 2021 Brain activity is composed of oscillatory and broadband arrhythmic components; however, there is more focus on oscillatory sensorimotor rhythms to study movement, but temporal dynamics of broadband arrhythmic electroencephalography (EEG) remain ...

Broadband Chaos Generated by an Optoelectronic Oscillator [PDF]
Physical Review Letters, 2010 We study an opto-electronic time-delay oscillator that displays high-speed chaotic behavior with a flat, broad power spectrum. The chaotic state coexists with a linearly-stable fixed point, which, when subjected to a finite-amplitude perturbation, loses stability initially via a periodic train of ultrafast pulses. We derive an approximate map that does

Broadband amplitude-stabilized oscillator [PDF]
The Eighth International Conference on Advanced Semiconductor Devices and Microsystems, 2010 In many applications we need oscillators tunable over a considerable frequency range by simple LC circuits with broadly varying dynamic resistances (quality factor Q of the reactances), while insisting on keeping a rather constant amplitude of the A.C.

Optical Parametric Oscillation with Ultra-Low Power Threshold in a Dimer of Active-Passive Cavities
Crystals, 2021 Optical parametric oscillation can convert the input laser into a couple of coherent optical output with signal and idler frequencies. It is an important method for the realization of the broadband middle infrared tunable lasers.

Broadband distortion modeling in Lyman-$\alpha$ forest BAO fitting [PDF]
, 2015 In recent years, the Lyman-$\alpha$ absorption observed in the spectra of high-redshift quasars has been used as a tracer of large-scale structure by means of the three-dimensional Lyman-$\alpha$ forest auto-correlation function at redshift $z\simeq 2.3$,

All-Optical Quantum Random Bit Generation from Intrinsically Binary Phase of Parametric Oscillators [PDF]
, 2012 True random number generators (RNGs) are desirable for applications ranging from cryptogra- phy to computer simulations. Quantum phenomena prove to be attractive for physical RNGs due to their fundamental randomness and immunity to attack [1]- [5 ...
