Detecting Current Noise with a Josephson Junction in the Macroscopic Quantum Tunneling Regime
, 2006 We discuss the use of a hysteretic Josephson junction to detect current fluctuations with frequencies below the plasma frequency of the junction. These adiabatic fluctuations are probed by switching measurements observing the noise-affected average rate ...

Advanced Functional Materials, EarlyView.This study uncovers a new switching mechanism in HfO2 and ZrO2, where the absence of a non‐polar layer along the a‐direction induces interaction between polar layers. Consequently, the switching barriers for growth are lower than those for nucleation in this direction, leading to a size‐dependent coercive field that matches experimental observations ...

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.

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
