Method of increasing the information capacity of associative memory of oscillator neural networks using high-order synchronization effect

open access: yes, 2018
Computational modelling of two- and three-oscillator schemes with thermally coupled $VO_2$-switches is used to demonstrate a novel method of pattern storage and recognition in an impulse oscillator neural network (ONN) based on the high-order ...

Quantum phase transition in the Dicke model with critical and non-critical entanglement

open access: yes, 2012
We study the quantum phase transition of the Dicke model in the classical oscillator limit, where it occurs already for finite spin length. In contrast to the classical spin limit, for which spin-oscillator entanglement diverges at the transition ...

A controllable superconducting electromechanical oscillator with a suspended membrane

open access: yes, 2019
We fabricate a microscale electromechanical system, in which a suspended superconducting membrane, treated as a mechanical oscillator, capacitively couples to a superconducting microwave resonator.

Wireless Powered Encoding and Broadcasting of Frequency Modulated Detection Signals

open access: yesIEEE Access, 2020
Wireless transmission of locally detected RF signals is necessary for long-term operation of batteryless and embedded transducers. To improve signal transmission efficiency over larger distances, multi-stage circuits were employed to down-convert RF ...

Stochastic Gene Expression in Single Gene Oscillator Variants [PDF]

open access: yes, 2016
It is infeasible to understand all dynamics in cell, but we can aim to understand the impact of design choices under our control. Here we consider a single gene oscillator as a case study to understand the influence of DNA copy number and repressor ...
