Multiple sequence alignment ( MSA) is the process or the result of sequence alignment of three or more biological sequences, generally protein, DNA, or RNA. These alignments are used to infer evolutionary relationships via phylogenetic analysis and can highlight homologous features between sequences. Alignments highlight mutation events such as ...
A measurement system analysis ( MSA) is a thorough assessment of a measurement process, and typically includes a specially designed experiment that seeks to identify the components of variation in that measurement process. Just as processes that produce a product may vary, the process of obtaining measurements and data may also have variation ...
The Huber loss function describes the penalty incurred by an estimation procedure f. Huber (1964) defines the loss function piecewise by [1] This function is quadratic for small values of a, and linear for large values, with equal values and slopes of the different sections at the two points where . The variable a often refers to the residuals ...
Specific surface area ( SSA) is a property of solids defined as the total surface area (SA) of a material per unit mass, [1] (with units of m 2 /kg or m 2 /g). Alternatively, it may be defined as SA per solid or bulk volume [2] [3] (units of m 2 /m 3 or m −1 ). It is a physical value that can be used to determine the type and properties of a ...
Provided that the probability distribution of X is such that the above expectation exists, ...
An income of $0.88 in Birmingham equals an income of $1.27 in San Jose with the U.S as a whole having an average PCPI of $1.00. To put it another way, the purchasing power of a dollar compared to the U.S. average is $1.13 in Birmingham and $0.79 in San Jose. The net impact of accounting for differences in the purchasing power of a dollar in ...
Business portal. Money portal. v. t. e. A medical savings account ( MSA) is an account into which tax-deferred amounts from income can be deposited. The amounts are often called contributions and may be made by a worker, an employer, or both, depending on a country's laws. The money in such accounts is to be used to pay for medical expenses.
Mass separating agent. In chemical separation processes, a mass separating agent ( MSA) is a chemical species that is added to ensure that the intended separation process takes place. It is analogous to an energy separating agent, which aids separations processes via addition of energy. An MSA may be partially immiscible with one or more ...
