Integration of Reconfigurable p‐Bit and 1R Crossbar Array for Memristive Probabilistic Computing
Advanced Science, EarlyView.A memristive probabilistic computing system is demonstrated by integrating stochastic p‐bits based on volatile memristors with a 1R crossbar array encoding interaction weights. The system performs weighted‐sum operations across the array and updates p‐bits iteratively.

Stock Volatility and the Crash of '87 [PDF]
This paper analyzes the behavior of stock return volatility using daily data from 1885 through 1987. The October 1987 stock market crash was unusual in many ways relative to prior history.

Selective Polarity Control of Metal Oxide Semiconductors for Complementary Logic Gates
Advanced Science, EarlyView.A scalable electrochemical doping strategy enables in situ p‐to‐n polarity conversion in tin oxide (SnO) thin films using electrolyte gating. Both the pristine p‐type SnO transistor and the electrochemically converted n‐type SnO2 transistor exhibited noticeable and stable electrical performance.

Battery‐Inspired Electrochemical Synapses for Neuromorphic Applications
Advanced Science, EarlyView.Battery‐ion‐inspired synaptic devices integrate diverse electrolyte systems (solid, ion‐gel, liquid) with transition metal oxides, two‐dimensional materials, and organic channels to regulate ion‐electron coupling. By tailoring ion transport and host interactions, these platforms enable controllable plasticity and energy‐efficient implementations for ...

Advanced Science, EarlyView.A conformal ALD‐IGZO vertical RRAM integrates volatile and nonvolatile switching within a compact 2F architecture. Before forming, tunable volatile dynamics provide fading‐memory reservoir states, while after forming, stable multilevel conductance modulation enables hardware readout.

Advanced Science, EarlyView.Vision begins not with images but with change: the retina fires only when something moves, handing the brain a stream of spikes. A neuromorphic imaging system adopts the same strategy—an event sensor that sees like the retina, a spiking network that thinks like the brain—to track and reconstruct fully randomly moving targets through tissue (phantom ...
