Stochastic impedance [PDF]

open access: yesPhysica A: Statistical Mechanics and its Applications, 2020
The concept of impedance, which characterises the current response to a periodical driving, is introduced in the context of stochastic transport. In particular, we calculate the impedance for an exactly solvable model, namely the stochastic transport of particles through a single-level quantum dot.

Cryopreservation of engineered tissues and organoids [PDF]

open access: yesOrganoid, 2023
Although engineering transplantable tissues for clinical applications is difficult, cryopreserving those tissues to create pre-made engineered tissue for emergency transplantation is an even greater challenge.

Preliminary study on parameterization of raw electrical bioimpedance data with 3 frequencies

open access: yesScientific Reports, 2022
This study tests the geometrical parameterization method for Electrical Bio-Impedance Spectroscopy (EBIS) readings previously proposed by one of the authors. This method uses the data of just three frequencies (therefore called 3P method).

Impedance scaling and impedance control [PDF]

open access: yesProceedings of the 1997 Particle Accelerator Conference (Cat. No.97CH36167), 2002
When a machine becomes really large, such as the Very Large Hadron Collider (VLHC), of which the circumference could reach the order of megameters, beam instability could be an essential bottleneck. This paper studies the scaling of the instability threshold vs. machine size when the coupling impedance scales in a "normal" way.
