Efficient Cell Impedance Measurement by Dielectrophoretic Cell Accumulation and Evaluation of Chondrogenic Phenotypes

open access: yesMicromachines, 2022
The quantitative and functional analyses of cells are important for cell-based therapies. In this study, to establish the quantitative cell analysis method, we propose an impedance measurement method supported by dielectrophoretic cell accumulation.

Traceable measurements of electrical impedance

open access: yesIEEE Instrumentation & Measurement Magazine, 2015
Scientists and engineers from different backgrounds share the need for measurement of electrical impedance and related quantities. Equivalent lumped resistance, capacitance, or inductance are common parameters in the characterization, specification, and design of electrical and electronic components.

ELECTRIC IMPEDANCE OF ARBACIA EGGS [PDF]

open access: yesJournal of General Physiology, 1936
The alternating current resistance and capacity of suspensions of unfertilized and fertilized eggs of Arbacia punctulata have been measured at frequencies from 103 to 1.64 x 107 cycles per second. The unfertilized egg has a static plasma membrane capacity of 0.73 µf./cm.2 which is practically independent of frequency.

2D electrical impedance tomography dataset

open access: yes, 2018
This is an open access electrical impedance tomography (EIT) dataset. The EIT measurements were collected from a circular body (a flat tank filled with saline) with various choices of conductive and resistive inclusions.

Self‐Regulated Learning Meets AI: Reinterpreting Self‐Regulation, Co‐Regulation, and Socially Shared Regulation in Human–AI Interaction

open access: yesNew Directions for Adult and Continuing Education, EarlyView.
ABSTRACT Advancing artificial intelligence (AI) has transformed learning and work, yet higher education and professional development programs have not systematically equipped learners for AI‐prevalent environments. This lack of preparation creates uncertainty regarding control, responsibility, trust, and accountability.

Analysis of impedance measurements of a suspension of microcapsules using a variable length impedance measurement cell

open access: yesJournal of Electrical Bioimpedance, 2012
Electrical impedance measurements of a suspension have to take into account the double layer impedance that results from a very thin charged layer formed at the electrode-electrolyte interface.

Electrical conductivity of polycrystalline uranium dioxide [PDF]

open access: yes, 1989
The electrical impedance of a disc-shaped sample of polycrystalline UO2 has been measured over a frequency range of 10 Hz to 10 MHz at temperatures between 108 and 380 K.

Elevated Connectivity During Language Processing Is Associated With Cognitive Performance in SeLECTS

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Self‐Limited Epilepsy with Centrotemporal Spikes (SeLECTS) is associated with language impairments despite seizures originating in the motor cortex, suggesting aberrant cross‐network interactions. Here we tested whether functional connectivity in SeLECTS during language tasks predicts language performance.

Optimal finite element modelling and efficient reconstruction in non-linear 3D electrical resistance tomography

open access: yes, 2001
Electrical Impedance Tomography can provide images with well-defined characteristics using a fully non-linear reconstruction process when appropriate constraints are imposed on the solution to allow the ill-posed inverse problem to be solved.
