A compact, low‐frequency, memristor‐based oscillator
International Journal of Circuit Theory and Applications, 2014SummaryA relaxation oscillator using a memristor is hereby presented. The memristor is used to substitute the function of a capacitor in an equivalent RC oscillator. The voltage across the memristor changes according to the quantity and polarity of the current passing through, thus substituting the changing voltage across a capacitor in the equivalent ...

Low-Frequency Brain Oscillations in Schizophrenia
JAMA Psychiatry, 2016Understanding thebrainnetworks thatproduce thesymptomsof schizophrenia is a major goal of modern neuroscience. There is increasing evidence that brain function depends critically on oscillations, and ithas thereforebeenof interest todeterminewhether the oscillatorypropertiesof thebrain areabnormal in schizophrenicpatients.

Low frequency temperature forcing of chemical oscillations
Physical Chemistry Chemical Physics, 2011The low frequency forcing of chemical oscillations by temperature is investigated experimentally in the Belousov-Zhabotinsky (BZ) reaction and in simulations of the Oregonator model with Arrhenius temperature dependence of the rate constants. Forcing with temperature leads to modulation of the chemical frequency.

Since the early 1970s and the early 1980s, the Madden-Julian Oscillation (MJO) in the tropics and some teleconnections in worldwide have respectively become two important topics in climate study. The former is moving low-frequency fluctuations while the latter is standing oscillations.

Nonlinear analysis of low frequency Oscillations in gyrotrons
2009 IEEE International Conference on Plasma Science - Abstracts, 2009Summary form only given: Low frequency oscillations attributed to reflected electrons bouncing between the electron gun and the interaction space have been observed in many gyrotrons. A nonlinear model is considered which allows one to develop the theory based on PIC simulations and apply it to the analysis of these oscillations.

Weak low-frequency electromagnetic oscillations in water
Electromagnetic Biology and Medicine, 2016Recent observations of low-frequency electromagnetic oscillations in water suggest an inductive structural component. Accordingly, we assume a helical basis enabling us to model water as an LC tuned oscillator. A proposed tetrahedral structure consisting of three water molecules and one hydronium ion is incorporated into the Boerdijk-Coxeter tetrahelix

Low Frequency Rotary Traveling Wave Oscillators
2018 IEEE International Symposium on Circuits and Systems (ISCAS), 2018A methodology is presented in order to automate the selection of a design style for low frequency operation of ultra low power rotary traveling wave oscillators (RTWOs). The methodology systemically analyzes the power dissipation profiles of design styles with two priori known resonant frequency dividers, a static and a dynamic frequency divider.

Low frequency oscillations in oscillators using Gunn diodes
International Journal of Electronics, 1973Abstract Experiments are reported which indicate that simultaneous oscillations at two frequencies may be generated in a Gunn diode oscillator. The lower frequency is within the range 1·8-0·44GHZ, while the higher frequency lies between 1·8 and 3·75 GHz, the transit-time frequency being l·8GHz.

Design of a Low-Frequency Oscillator with PTC Memristor and an Inductor
International Journal of Bifurcation and Chaos, 2016An electronic oscillator circuit is designed by connecting an inductor in series with a locally-active PTC Memristor and a battery. The PTC Memristor is locally active on the negative resistance region of its DC [Formula: see text]–[Formula: see text] curve.
