This is about 1000 times greater than mutation rates measured in Drosophila and other organisms and much higher than recorded for the sickle-cell locus in Africans. [70] To balance the polymorphism, Anthony Allison estimated that the fitness of the AS heterozygote would have to be 1.26 times than that of the normal homozygote.
The group delay and phase delay properties of a linear time-invariant (LTI) system are functions of frequency, giving the time from when a frequency component of a time varying physical quantity—for example a voltage signal—appears at the LTI system input, to the time when a copy of that same frequency component—perhaps of a different physical phenomenon—appears at the LTI system output.
Mutational robustness (also called mutation tolerance) describes the extent to which an organism's phenotype remains constant in spite of mutation. [9] Robustness can be empirically measured for several genomes [10] [11] and individual genes [12] by inducing mutations and measuring what proportion of mutants retain the same phenotype, function or fitness.
When U is smaller than or considerably larger than one, it becomes relatively useless. [2] While Mason's Invariant can be used as a figure of merit across all operating frequencies, its value at ƒ max is especially useful. ƒ max is the maximum oscillation frequency of a device, and it is discovered when () =.
Resistance to a drug. A resistance mutation is a mutation in a virus gene that allows the virus to become resistant to treatment with a particular antiviral drug.The term was first used in the management of HIV, the first virus in which genome sequencing was routinely used to look for drug resistance.
High-Order Differential Power Analysis (HO-DPA) is an advanced form of DPA attack. HO-DPA enables multiple data sources and different time offsets to be incorporated in the analysis. HO-DPA is less widely practiced than SPA and DPA, as the analysis is complex and most vulnerable devices can be broken more easily with SPA or DPA. [2]
In electrical engineering, antiresonance is the condition for which the reactance vanishes but the resistive impedance of an electrical circuit is none the less very high, approaching infinity. In an electric circuit consisting of a capacitor and an inductor in parallel , antiresonance occurs when the alternating current line voltage and the ...
The Q factor is a parameter that describes the resonance behavior of an underdamped harmonic oscillator (resonator). Sinusoidally driven resonators having higher Q factors resonate with greater amplitudes (at the resonant frequency) but have a smaller range of frequencies around that frequency for which they resonate; the range of frequencies for which the oscillator resonates is called the ...
