Phase transitions in single neurons and neural populations: Critical slowing, anesthesia, and sleep cycles [PDF]
, 2010 The firing of an action potential by a biological neuron represents a dramatic transition from small-scale linear stochastics (subthreshold voltage fluctuations) to gross-scale nonlinear dynamics (birth of a 1-ms voltage spike). In populations of neurons

Advanced Functional Materials, EarlyView.An all‐in‐one analog AI accelerator is presented, enabling on‐chip training, weight retention, and long‐term inference acceleration. It leverages a BEOL‐integrated CMO/HfOx ReRAM array with low‐voltage operation (<1.5 V), multi‐bit capability over 32 states, low programming noise (10 nS), and near‐ideal weight transfer.

A novel soft switching crossing current resonant converter (XCRC) [PDF]
, 1994 Unlike other resonate or soft-switching converter, this novel topology employs only two switches and a very simply control method. The inherent constant power protection feature is another merit. No special resonate chip is needed to control the circuit.

Laser‐Induced Graphene from Waste Almond Shells
Advanced Functional Materials, EarlyView.Almond shells, an abundant agricultural by‐product, are repurposed to create a fully bioderived almond shell/chitosan composite (ASC) degradable in soil. ASC is converted into laser‐induced graphene (LIG) by laser scribing and proposed as a substrate for transient electronics.

Analysis of Intrinsic Switching Losses in Superjunction MOSFETs Under Zero Voltage Switching
Energies, 2020 Switching losses of power transistors usually are the most relevant energy losses in high-frequency power converters. Soft-switching techniques allow a reduction of these losses, but even under soft-switching conditions, these losses can be significant ...
