Ultra‐Fast Non‐Volatile Resistive Switching Devices with Over 512 Distinct and Stable Levels for Memory and Neuromorphic Computing

open access: yesAdvanced Functional Materials, EarlyView.
A materials and device design concept that comprises a self‐assembled ultra‐thin epitaxial ion‐transporting layer, an amorphous oxide overcoat oxygen‐blocking layer, and a partial filament formed during an electroforming step is proposed for low‐current multilevel resistive switching devices.

Two-stage Temporal Modelling Framework for Video-based Depression Recognition using Graph Representation [PDF]

open access: yesarXiv, 2021
Video-based automatic depression analysis provides a fast, objective and repeatable self-assessment solution, which has been widely developed in recent years. While depression clues may be reflected by human facial behaviours of various temporal scales, most existing approaches either focused on modelling depression from short-term or video-level ...

Tin‐Based 2D/3D Perovskite Vertical Heterojunction for High‐Performance Synaptic Phototransistors

open access: yesAdvanced Functional Materials, EarlyView.
Phototransistors based on tin‐based 2D/3D perovskite heterostructures show an ultrahigh responsivity and detectivity at a low gate voltage across a broad wavelength region from ultraviolet to near‐infrared. The devices can replicate neuromorphic learning and remembering behaviors to light stimuli, in addition to electric depression and memory erasure ...

Information cascades and the distribution of economic recessions in the United States [PDF]

open access: yes, 2004
The American economy can be thought of as a highly connected random network in terms of both its technological and informational connections. The cumulative size of economic recessions, the fall in output from peak to trough, is analysed for the US economy 1900-2002.

Supercompliant Lattice Boosts n‐type AgSbTe2 Thermoelectrics

open access: yesAdvanced Functional Materials, EarlyView.
The supercompliant lattice design enables the first realization of n‐type electrical transport in AgSbTe2 by overcoming intrinsic electron‐killer defects and exceeding the doping limits imposed by the conventional Hume–Rothery rule. Accordingly, the best performance n‐type Ag0.8Na0.3Sb0.6Bi0.4Te2 sample achieves a low κ of 0.27 W·m−1·K−1 that ...

“Riffraff” On the Waterfront: A Critical Analysis of Labor Imagery on the Imagined Docks of the Hollywood Dream Factory, 1934–1937

open access: yesOpen Cultural Studies, 2021
At the height of the Great Depression, the American Labor Movement was ascendant as union strongholds and the belief in the power of collective action and labor solidarity were re-asserted. The energy and activism along the west-coast waterfront fomented

Hollow‐Structured Nanorobot with Excellent Magnetic Propulsion for Catalytic Pollutant Degradation, Anti‐Bacterial and Biofilm Removal

open access: yesAdvanced Healthcare Materials, EarlyView.
A hollow‐structured Fe3O4@AgAu@PDA‐ZnPc nanosphere has been developed, exhibiting controllable catalytic activity and “photothermal‐photodynamic‐Ag+” coupling antibacterial characteristics. When subjected to a rotating magnetic field, these performances are uniquely enhanced by magnetic propulsion, allowing the nanosphere to function as a magnetic ...

Claim Detection in Biomedical Twitter Posts [PDF]

open access: yesarXiv, 2021
Social media contains unfiltered and unique information, which is potentially of great value, but, in the case of misinformation, can also do great harm. With regards to biomedical topics, false information can be particularly dangerous. Methods of automatic fact-checking and fake news detection address this problem, but have not been applied to the ...
