Characterization of two pathological gating-charge substitutions in Cav1.4 L-type calcium channels

open access: yesChannels, 2023
Cav1.4 L-type calcium channels are predominantly expressed at the photoreceptor terminals and in bipolar cells, mediating neurotransmitter release. Mutations in its gene, CACNA1F, can cause congenital stationary night-blindness type 2 (CSNB2).

CONTRIBUTIONS OF INTRACELLULAR IONS TO Kv CHANNEL VOLTAGE SENSOR DYNAMICS.

open access: yesFrontiers in Pharmacology, 2012
Voltage sensing domains of Kv channels control ionic conductance through coupling of the movement of charged residues in the S4 segment to conformational changes at the cytoplasmic region of the pore domain, that allow K+ ions to flow.

Research and Experiments on a Unipolar Capacitive Voltage Sensor

open access: yesSensors, 2015
Voltage sensors are an important part of the electric system. In service, traditional voltage sensors need to directly contact a high-voltage charged body. Sensors involve a large volume, complex insulation structures, and high design costs. Typically an

A comparative study of methods for estimating virtual flux at the point of common coupling in grid connected voltage source converters with LCL filter [PDF]

open access: yes, 2016
Grid connected Voltage Source Converters (VSCs) with LCL filters usually have voltage measurements at the filter capacitors, while it can be important to control the active or reactive power injection at the grid-side of the LCL filter, for instance at a

Acoustic energy transmission in cast iron pipelines [PDF]

open access: yes, 2015
In this paper we propose acoustic power transfer as a method for the remote powering of pipeline sensor nodes. A theoretical framework of acoustic power propagation in the ceramic transducers and the metal structures is drawn, based on the Mason ...

Design of a single-chip pH sensor using a conventional 0.6-μm CMOS process [PDF]

open access: yes, 2004
A pH sensor fabricated on a single chip by an unmodified, commercial 0.6-/spl μm CMOS process is presented. The sensor comprises a circuit for making differential measurements between an ion-sensitive field-effect transistor (ISFET) and a reference ...
