Dual‐Mode Nanoporous SiO2 Memristors with Coexisting Volatile and Nonvolatile Dynamics for Reservoir Computing

Advanced Science, Volume 13, Issue 51, 14 September 2026.
A nanoporous SiO2 memristor enabling reconfigurable volatile and non‐volatile switching within a single device is demonstrated. The dual‐mode functionality supports both physical reservoir dynamics and synaptic weight storage, allowing unified hardware implementation of reservoir computing for temporal information processing, including image and ...

Offline Handwritten Signature Database based on Gender Annotation

, 2022
It has been found that the publicly available standard image datasets of handwritten signatures do not have gender annotation. With this motivation, own dataset is created. The nature of this own offline handwritten signature database is described below.

Highly‐Uniform Passive Crossbar Arrays of Resistive Switching Random Access Memory (RRAM) for In‐Memory Computing Applications

Advanced Electronic Materials, Volume 12, Issue 18, 21 September 2026.
Passive resistive memory arrays promise efficient in‐memory computing but suffer from sneak paths and programming variability. Here, highly uniform 32 × 32 passive RRAM crossbars are programmed with multilevel precision below 3% error and 99.5% yield.

Fixed-sized representation learning from offline handwritten signatures of different sizes [PDF]

International Journal on Document Analysis and Recognition (IJDAR), 2018
Methods for learning feature representations for Offline Handwritten Signature Verification have been successfully proposed in recent literature, using Deep Convolutional Neural Networks to learn representations from signature pixels. Such methods reported large performance improvements compared to handcrafted feature extractors.

Programmable van der Waals Heterojunction for Multifunctional Integration

SmartMat, Volume 7, Issue 4, August 2026.
A MoS2/MAPbBr3 van der Waals heterostructure is programmed by gate bias to switch among photodetector, synaptic transistor, and gate‐bias‐assisted optical‐memory modes. Gate‐controlled carrier trapping tunes the response timescale, enabling mode reconfiguration in a single device.
