Optimal receptor-cluster size determined by intrinsic and extrinsic noise.
Biological cells sense external chemical stimuli in their environment using cell-surface receptors. To increase the sensitivity of sensing, receptors often cluster. This process occurs most noticeably in bacterial chemotaxis, a paradigm for sensing and signaling in general. While amplification of weak stimuli is useful in the absence of noise, its usefulness is less clear in the presence of ext...
متن کاملIntrinsic and Extrinsic Size Effects
The processing, electromechanical properties, and microstructure of lead zirconate titanate (PZT) ceramics over the grain-size range of 0.1–10 μm were studied. Using measurements over a large temperature range (15–600 K), the relative role of extrinsic contribution (i.e., domain-wall motion) was deduced to be influenced strongly by the grain size, particularly for donor-doped PZT. Analytical tr...
متن کاملInferring intrinsic and extrinsic noise from a dual fluorescent reporter
Dual fluorescent reporter constructs, which measure gene expression from two identical promoters within the same cell, allow total gene expression noise to be decomposed into an extrinsic component, roughly associated with cell-to-cell fluctuations in cellular component concentrations, and intrinsic noise, roughly associated with inherent stochasticity of the biochemical reactions involved in g...
متن کاملStochastic synchronization of neuronal populations with intrinsic and extrinsic noise
We extend the theory of noise-induced phase synchronization to the case of a neural master equation describing the stochastic dynamics of an ensemble of uncoupled neuronal population oscillators with intrinsic and extrinsic noise. The master equation formulation of stochastic neurodynamics represents the state of each population by the number of currently active neurons, and the state transitio...
متن کاملA Study of Intrinsic and Extrinsic Motivation Iranian mysticism gravamen
Gravamen is a kind of lyrical literature in which human tries own suffering and distress to reveal the audience. There are several types of gravamen. One of them is the mystical breakthrough that comes from the intrinsic and extrinsic motivation. Including Intrinsic motivations can be mentioned the sadness of separation from partner, the sadness of separation from partner, sensual temptations, ...
