Nanoscale radiofrequency impedance sensors with unconditionally stable tuning. [PDF]
J Appl Phys, 2009 Impedance sensors perform an important role in a number of biosensing applications, including particle counting, sizing, and velocimetry. Detection of nanoparticles, or changes in, e.g., the interfacial Debye–Hückel layer, can also be performed using nanoscale impedance sensors.

Flume Tests to Investigate the Initiation Mechanism of Loess Mudflows on the Chinese Loess Plateau
Frontiers in Earth Science, 2021 Loess has a strong water sensitivity, so loess landslides often transform into loess mudflows when water is added on the Chinese Loess Plateau, which results in high casualties and property loss of the Chinese government. In this study, a series of flume

An unconditionally stable Voltage Regulator [PDF]
2010 IEEE Asia Pacific Conference on Circuits and Systems, 2010 This paper describes a CMOS implementation of a Linear Voltage Regulator (LVR) used to power implanted systems. The topology is based on a classical structure of a Low Dropout Regulator (LDO) and receives his activation energy from a RF link characterizing a passive RFID tag. The LVR was designed to achieve important features like low power consumption,

Unconditionally Stable Algorithm for Copolymer and Copolymer-Solvent Systems
Papers in Physics, 2020 In the time evolution simulation of a copolymer system towards its equilibrium configuration, it is common to use the Otha-Kawasaki approach for free energy and time evolution by means of a Cahn-Hilliard diffusion equation.
