The modulation of gene expression in response to oscillations in cell-population density is thanks to the QS techniques regulating bacterial communication natural and artificial cultures. It is also clear that intra- and inter-species cell–cell communication occurs and is regulated by quorum sensing systems.
It is not only the presence or absence of a signal that is important but also the strength. Using a chemical gradient to coordinate cell growth and differentiation continues to be important as multicellular animals and plants become more complex. This type of intercellular communication within an organism is commonly referred to as cell signalling.
The molecules are delivered into communications media such as air and water for transmission. The technique also is not subject to the requirement of using antennas that are sized to a specific ratio of the wavelength of the signal. Molecular communication signals can be made biocompatible and require very little energy. [2] [3]
ChemComm (or Chemical Communications), formerly known as Journal of the Chemical Society D: Chemical Communications (1969–1971), Journal of the Chemical Society, Chemical Communications (1972–1995), [1] is a peer-reviewed scientific journal published by the Royal Society of Chemistry. [2]
In supramolecular chemistry, [1] host–guest chemistry describes complexes that are composed of two or more molecules or ions that are held together in unique structural relationships by forces other than those of full covalent bonds. Host–guest chemistry encompasses the idea of molecular recognition and interactions through non-covalent ...
The physical manifestation of leaving group ability is the rate at which a reaction takes place. Good leaving groups give fast reactions. By transition state theory, this implies that reactions involving good leaving groups have low activation barriers leading to relatively stable transition states.
Elon Musk said Starlink satellite internet is inactive in India, his first comments since authorities seized two of the company's devices in recent weeks, one in an armed conflict zone and another ...
The Shannon limit or Shannon capacity of a communication channel refers to the maximum rate of error-free data that can theoretically be transferred over the channel if the link is subject to random data transmission errors, for a particular noise level.
