[1] [7] The sensitivity towards voltage is largely attributed to the gap junction’s cytoplasmic NH2-terminal which is responsive to small voltages (2-3mV). [ 7 ] [ 9 ] Voltage gating modulation is associated with the charge of connexin ; positively charged connexin close with hyperpolarization and negatively charged connexins close with ...
Acoustic communication is widespread in both aquatic and semi-aquatic invertebrates and vertebrates, [5] with many species capable of using both infrasound and ultrasound for communication. As sound travels faster and over a larger distance in water than in air, aquatic animals can use sound signals for long-distance communication while ...
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]
When the power is expressed in dBm the larger the absolute value of the negative number, the better the receive sensitivity. For example, a receiver sensitivity of −98 dBm is better than a receive sensitivity of −95 dBm by 3 dB, or a factor of two. In other words, at a specified data rate, a receiver with a −98 dBm sensitivity can hear ...
Schematic of energy levels involved in two photons absorption. In atomic physics, two-photon absorption (TPA or 2PA), also called two-photon excitation or non-linear absorption, is the simultaneous absorption of two photons of identical or different frequencies in order to excite an atom or a molecule from one state (usually the ground state), via a virtual energy level, to a higher energy ...
A minimum detectable signal is a signal at the input of a system whose power allows it to be detected over the background electronic noise of the detector system. It can alternately be defined as a signal that produces a signal-to-noise ratio of a given value m at the output. In practice, m is usually chosen to
When scientists found a carcinogen in Santa Rosa's drinking water after the Tubbs fire, it triggered a race to develop measures to keep residents safe. The L.A. fires put them to the test.
In wireless communications, channel state information (CSI) is the known channel properties of a communication link.This information describes how a signal propagates from the transmitter to the receiver and represents the combined effect of, for example, scattering, fading, and power decay with distance.
