International audience; Stochastic resonance is a noise phenomenon that benefits applications such as pattern formation, neural systems, microelectromechanical systems, and image processing. This study experimentally clarifies that the orientation of

Autor: Hiroshi Orihara, Fumiaki Kobayashi, Shuji Fujii, Yuji Sasaki, Tomoyuki Nagaya
Publikováno v: Physical Review E. 101(2):022702
Recently, we reported the discovery of enormous negative viscosity of a nematic liquid crystal in the presence of turbulence induced by ac electric fields, which enabled us to observe unique phenomena related to the negative viscosity, such as sponta

Publikováno v: Physical review. E. 99(1-1)
We report on the discovery of enormous negative viscosity in a nematic liquid crystal in the presence of turbulence induced by electric fields. As the negative viscosity in this system is so large, we are able to observe several phenomena originating

A Pseudo-neuron Device and Firing Dynamics of Their Networks Similar to Neural Synchronizing Phenomena Between Far Local Fields in the Brain
Autor: Ichiro Tsuda, Tomoyuki Yano, Yoshitomo Goto, Tomoyuki Nagaya, Shigetoshi Nara
Publikováno v: Advances in Cognitive Neurodynamics (VI) ISBN: 9789811088537
A pseudo-neuron hardware device called dynamic self-electrooptic effect device (DSEED) is proposed and considered. First, its neuron-like pulsed oscillations ((i) fast spiking type, (ii) threshold spiking type) are theoretically predicted, and their
