Advanced Science, EarlyView.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 ...

Modeling polycrystals with regular polyhedra
Materials Research, 2006 Polycrystalline structure is of paramount importance to materials science and engineering. It provides an important example of a space-filling irregular network structure that also occurs in foams as well as in certain biological tissues.

Semisimplicity and von Neumann's regularity
Semigroup Forum, 1971 The purpose of this paper is to link semigroup theory and category theory by using Green's relations to study regular morphisms and semisimple objects in a category which is filtering in the sense that every morphism admits an epic-monic factorization. For example, the following results are shown for a filtering category C ∶ (1)C is regular if and only

Anisotropic Memristive Switching in NbOCl2 Enabled by Directional Oxygen Ion Migration
Advanced Science, EarlyView.This study investigates strongly orientation‐dependent memristive switching in anisotropic NbOCl2, observed exclusively along the in‐plane c‐axis. The switching originates from direction‐selective oxygen‐ion migration and vacancy propagation that modulate the Pd/NbOCl2 Schottky barrier, enabling short‐term plasticity.

Advanced Science, EarlyView.A non‐filamentary self‐rectifying HfO2/TiOx resistive random‐access memory integrates H2 annealing with an incremental step pulse with verify algorithm to achieve stable and linear analog conductance modulation. The device enables low‐current 6‐bit multilevel operation while suppressing sneak current in crossbar arrays. Implemented in Transformer‐based

Investigation of Flow Control for the Hypersonic Inlets via Counter Flow
International Journal of Aerospace Engineering, 2015 Experimental results show that there exist two flow fields in the hypersonic inlets when the forebody waves interact with the lip boundary, which is similar to the shock reflection ion hysteresis phenomenon.

Hierarchical Multi‐Mode Computing in Interlayer‐Coupled 3D RRAM Crossbar Arrays
Advanced Science, EarlyView.2‐deck RRAM crossbar array provides a versatile hardware platform for multifunctional in‐memory computing. Stacked, series, and entropy node configurations enable multi‐layer conductance modulation, logic‐in‐memory operation, genetic learning, and reconfigurable physical unclonable functions.
