Monolithic 3D‐Integrated All‐Solid Ion‐Gated Carbon Nanotube Transistors With Tunable Ionic Conductance for Multi‐Timescale Reservoir Computing

Advanced Materials, EarlyView.
A dual‐timescale reservoir based on monolithically 3D (M3D)‐integrated CNT solid ion‐gated transistors is demonstrated. Tunable ionic dynamics and pulse‐engineered operation enable linear and symmetric synaptic updates. The M3D‐integrated array achieves robust temporal encoding and accurate classification of moving MNIST sequences, highlighting its ...

Robustness of mean-square exponential dichotomies for linear stochastic equations

Electronic Journal of Differential Equations, 2017
We present the notion of mean-square exponential dichotomies for linear stochastic differential equations. We study the robustness of the mean-square exponential dichotomies, in the sense of the existence of a mean-square exponential dichotomy for a ...
