Salen refers to a tetradentate C 2-symmetric ligand synthesized from salicylaldehyde (sal) and ethylenediamine (en).It may also refer to a class of compounds, which are structurally related to the classical salen ligand, primarily bis-Schiff bases.
At date t = 1, this investment opportunity is considered favorable; hence, this function is: −δC + δ^2 B > 0. Now consider from the perspective of date t = 2, this investment opportunity is still viewed as favorable given −C + δB > 0. To view this mathematically, observe that the new expression is the old expression multiplied by 1/δ.
Ligand efficiency is a measurement of the binding energy per atom of a ligand to its binding partner, such as a receptor or enzyme. [1]Ligand efficiency is used in drug discovery research programs to assist in narrowing focus to lead compounds with optimal combinations of physicochemical properties and pharmacological properties.
The prediction model can have varying levels of sophistication and accuracy, ranging from a crude heuristic to the use of complex predictive analytics techniques. Customer lifetime value can also be defined as the monetary value of a customer relationship, based on the present value of the projected future cash flows from the customer ...
The concept of the stochastic discount factor (SDF) is used in financial economics and mathematical finance. The name derives from the price of an asset being computable by "discounting" the future cash flow x ~ i {\displaystyle {\tilde {x}}_{i}} by the stochastic factor m ~ {\displaystyle {\tilde {m}}} , and then taking the expectation.

Chemometrics is the science of extracting information from chemical systems by data-driven means. Chemometrics is inherently interdisciplinary, using methods frequently employed in core data-analytic disciplines such as multivariate statistics, applied mathematics, and computer science, in order to address problems in chemistry, biochemistry, medicine, biology and chemical engineering.
Econophysics is a non-orthodox (in economics) interdisciplinary research field, applying theories and methods originally developed by physicists in order to solve problems in economics, usually those including uncertainty or stochastic processes and nonlinear dynamics.
The parameter is a constant which denotes the discount value subtracted from the count of each n-gram, usually between 0 and 1. The value of the normalizing constant λ w i − 1 {\displaystyle \lambda _{w_{i-1}}} is calculated to make the sum of conditional probabilities p K N ( w i | w i − 1 ) {\displaystyle p_{KN}(w_{i}|w_{i-1})} over all ...
