Dual-Band Band-Pass Filter with Fixed Low Band and Fluidically-Tunable High Band
In this work, we present a dual-band band-pass filter with fixed low-band resonant frequency and tunable high-band resonant frequency. The proposed filter consists of two split-ring resonators (SRRs) with a stub and microfluidic channels.

Control of scroll wave turbulence using resonant perturbations [PDF]
Turbulence of scroll waves is a sort of spatio-temporal chaos that exists in three-dimensional excitable media. Cardiac tissue and the Belousov-Zhabotinsky reaction are examples of such media.

Bayesian models for the determination of resonant frequencies in a DI diesel engine [PDF]
A time series method for the determination of combustion chamber resonant frequencies is outlined. This technique employs the use of Markov-chain Monte Carlo (MCMC) to infer parameters in a chosen model of the data.
