In molecular biology, transformation efficiency is a crucial parameter, it is used to evaluate the ability of different methods to introduce plasmid DNA into cells and to compare the efficiency of different plasmid, vectors and host cells. This efficiency can be affected by a number of factors, including the method used for introducing the DNA ...
Heritability is a statistic used in the fields of breeding and genetics that estimates the degree of variation in a phenotypic trait in a population that is due to genetic variation between individuals in that population. [ 1] The concept of heritability can be expressed in the form of the following question: "What is the proportion of the ...
Cell counting. Cell counting is any of various methods for the counting or similar quantification of cells in the life sciences, including medical diagnosis and treatment. It is an important subset of cytometry, with applications in research and clinical practice. For example, the complete blood count can help a physician to determine why a ...
In probability theory, the coupon collector's problem refers to mathematical analysis of "collect all coupons and win" contests. It asks the following question: if each box of a given product (e.g., breakfast cereals) contains a coupon, and there are n different types of coupons, what is the probability that more than t boxes need to be bought ...
Coalescent theory. Coalescent theory is a model of how alleles sampled from a population may have originated from a common ancestor. In the simplest case, coalescent theory assumes no recombination, no natural selection, and no gene flow or population structure, meaning that each variant is equally likely to have been passed from one generation ...
The interest in each such period (or partial period) is then computed, and then the amounts are summed over the number of quasi-coupon periods. For details, see or the ISDA paper. [4] This method ensures that all coupon payments are always for the same amount. It also ensures that all days in a coupon period are valued equally.
Biological half-life. Time course of drug plasma concentrations over 96 hours following oral administrations every 24 hours (Ï„). Absorption half-life 1 h, elimination half-life 12 h. Biological half-life ( elimination half-life, pharmacological half-life) is the time taken for concentration of a biological substance (such as a medication) to ...
The definition of the Clopper–Pearson interval can also be modified to obtain exact confidence intervals for different distributions. For instance, it can also be applied to the case where the samples are drawn without replacement from a population of a known size, instead of repeated draws of a binomial distribution.
