Oxygen‐Scavenging‐Driven Interlayer Engineering for Balancing Linearity and Retention in IGZO Synaptic Memristors

Advanced Electronic Materials, EarlyView.
Oxygen‐scavenging‐induced self‐formed interlayers regulate Schottky‐barrier modulation in IGZO memristors, producing a fundamental trade‐off between synaptic update linearity and retention. A preserved AlOx interlayer moderates voltage distribution and enables gradual, nearly linear conductance updates, whereas a soft‐broken SiO2 interlayer provides a ...

Reliable Ru‐Based CBRAM Synapses for Energy‐Efficient Neuromorphic Computing: Suppressing Filament Overgrowth and Read Noise via Ru‐Pt Alloy and AlOx Engineering

Advanced Electronic Materials, EarlyView.
Ru–Pt alloying suppresses filament overgrowth and an AlOx switching layer enhances reliable switching, hopping transport enables conductance tuning via hopping distance modulation, Ru7Pt3/AlOx/Pt device yields 16 low‐noise conductance states, a 2–3‐fold improvement over prior Ru‐based CBRAM, and CSNN inference on FMNIST reaches 81% accuracy with 103 ...

A Comprehensive Review of Fault‐Current Limiter Technologies for Smart and Resilient Power Systems

Energy Science &Engineering, EarlyView.
This review compares superconducting, solid‐state, and hybrid fault‐current limiters (FCLs) for modern alternating current, direct current, and hybrid grids. It shows that optimal FCL selection depends on fault characteristics, network configuration, voltage level, protection coordination, and resilience requirements rather than on a universally ...

Ultra‐Efficient Memristive Voltage‐Resistance Logic Framework With Integrated Readout Strategy Based on Hafnium Zirconium Oxide

Small Methods, EarlyView.
Spatiotemporal efficiency is a key concern in memristor‐based logic‐in‐memory architectures, where separate read operations to access resistance states fundamentally limit efficiency. This work demonstrates that logic outputs can be directly inferred from the intrinsic discharge dynamics of a two‐terminal memristive device.

Targeting ligament boundaries rather than alignment boundaries in augmented‐reality‐assisted total knee arthroplasty ensures comparable gait patterns between operated and contralateral limbs

Knee Surgery, Sports Traumatology, Arthroscopy, Volume 34, Issue 10, Page 3664-3674, October 2026.
Abstract Purpose Modern personalised total knee arthroplasty (TKA) techniques aim to mimic natural knee kinematics by focusing on soft‐tissue dynamics rather than static alignment. However, a consistent definition of the optimal ligamentous balance has not yet been established.

A novel multi-task learning method for evaluating short-term voltage stability with incomplete PMU measurements

Complex & Intelligent Systems, 2023
Methods for short-term voltage stability (STVS) assessment based on phasor measurement unit (PMU) data have become quite abundant. However, most of them are challenged to deal with the commonly encountered incomplete PMU data.
