Spatiotemporal Reservoir Computing with a Reconfigurable Multifunctional Memristor Array

Advanced Materials, EarlyView.
This study presents a hardware physical reservoir computing system using a tri‐modal memristive crossbar array. Stochastic masking, bistable nonlinear activation, and analog readout enable fully in‐memory spatiotemporal processing. Demonstrations on cellular automata, Lorenz prediction, ADHD EEG classification, and chaotic KS modeling highlight its ...

Sigmoid Neural Transfer Function Realised by Percolation

, 1996
An experiment using the phenomenon of percolation has been conducted to demonstrate the implementation of neural functionality (summing and sigmoid transfer). A simple analog approximation to digital percolation is implemented.

Learning Crystallographic Disorder: Bridging Prediction and Experiment in Materials Discovery

Advanced Materials, EarlyView.
Machine learning based computational materials discovery workflows have recently proposed thousands of potentially stable crystalline materials. However, the experimental realization of these predictions is often challenging because the models assume perfectly ordered structures.

Multimaterial Microrobots for pH Sensing Fabricated Using Sequential 3D and 4D Printing with Automated Alignment

Advanced Materials Technologies, EarlyView.
This work proposes the use of multimaterial microrobots for pH sensing. The microrobots consist of a hard polymer backbone and 4D printed sensing elements made of a pH‐responsive hydrogel. The swelling response, reusability, and high mobility of the microrobots make them promising tools for pH sensing at the micro scale.

Coefficient Bounds for Bazilevic Functions Associated with Modified Sigmoid Function [PDF]

Asian Research Journal of Mathematics, 2017
The focus of the present paper is to obtain the sharp upper bounds of  a2 (α) and a3 (α) for functions belonging to the Bazilevic class B(α,n,γ,ø)   associated with modified sigmoid function. The connection of these bounds to the celebrated Fekete-Szego functional | a3(α)- µa22 (α)|  follows as simple consequence.
