Adaptive response and enlargement of dynamic range [PDF]

, 2011
Many membrane channels and receptors exhibit adaptive, or desensitized, response to a strong sustained input stimulus, often supported by protein activity-dependent inactivation.

Distributed Strain Measurement Using Power-Based Brillouin Sensor with Three Folded Dynamic Range

Proceedings, 2019
We clarify that, unlike time-domain techniques, slope-assisted Brillouin optical correlation-domain reflectometry has a trade-off relation between the strain dynamic range and the spatial resolution.

Genetically Encoded Ratiometric pH Sensors for the Measurement of Intra- and Extracellular pH and Internalization Rates

Biosensors, 2022
pH-sensitive fluorescent proteins as genetically encoded pH sensors are promising tools for monitoring intra- and extracellular pH. However, there is a lack of ratiometric pH sensors, which offer a good dynamic range and can be purified and applied ...

Dynamic range of hypercubic stochastic excitable media [PDF]

, 2008
We study the response properties of d-dimensional hypercubic excitable networks to a stochastic stimulus. Each site, modelled either by a three-state stochastic susceptible-infected-recovered-susceptible system or by the probabilistic Greenberg-Hastings ...
