Multisolving innovations: How digital equity, e‐waste, and right‐to‐repair policies can increase the supply of affordable computers

open access: yesPolicy &Internet, Volume 15, Issue 2, Page 162-177, June 2023., 2023
Abstract Policy debates about the digital divide often focus on the availability and quality of Internet access, despite the fact that device inequities are persistent and widespread. To address this important but often overlooked policy concern, we present findings from a systematic literature review of policy research that informs the supply of low ...

电子学习中的情感计算 [PDF]

open access: yes, 2004
电子学习(E-learning)也称在线学习,是指利用互联网技术来设计、执行、选择、管理、支持和扩展的学习活动,包括电子阅读、多媒体远程教育、虚拟教室、数字图书馆和电子出版等网络学习的各种形式。众所周知,人随时随地都会有喜怒哀乐等情感的起伏变化,而人的情绪状态及其变化会对学习活动的绩效有重要影响。那么,在电子学习过程中,计算机是否能觉察学习者的情绪状态,并见机行事呢?所谓的情感计算(affective computing)就是试图赋予计算机像人一样的观察 ...

Electrically Switchable Altermagnetism in Monolayer MoCl3

open access: yesRare Metals, Volume 45, Issue 9, September 2026.
ABSTRACT Altermagnets intertwine spin‐split bands with vanishing net magnetization, offering great potential for high‐density, stray‐field‐free spintronic devices. However, their development is hindered by both material scarcity and difficulties in external control due to their intrinsic symmetry protection.

Anchoring Polyoxometalate (PMo11Fe) on ZnO Nanosheet for Construction of a Novel S‐Scheme Heterojunction Toward Efficient Photodegradation of Levofloxacin Antibiotics

open access: yesRare Metals, Volume 45, Issue 9, September 2026.
ABSTRACT Currently, the photocatalytic performance of ZnO has been severely limited by its weak light response ability and sluggish charge carrier dynamics, which considerably hinder its extensive application in photocatalytic fields. Herein, through anchoring the synthesized K6PMo11FeO40·nH2O (PMo11Fe) onto ZnO nanosheets, a novel S‐scheme ...

Beyond Photoreceptors: Bio‐Inspired Neuromorphic Vision System Mimicking Drosophila's Downstream Neural Circuitry With 2D β‐Ga2O3 Schottky Diodes

open access: yesRare Metals, Volume 45, Issue 7, July 2026.
ABSTRACT Bio‐inspired artificial vision systems have made significant progress, but most focus on photo‐receptors, neglecting the hardware implementation of the efficient downstream neural circuits for complex computations like motion detection. To overcome this bottleneck, we demonstrate a neuromorphic vision system that mimics Drosophila's motion ...
