    en.wikipedia.org/wiki/Broadbent's_filter_model_of...

    Broadbent was the first to describe the human attentional processing system using an information processing metaphor. [2] In this view, Broadbent proposed a so-called "early selection" view of attention, such that humans process information with limited capacity and select information to be processed early.

    Additionally, many schools add .33 for a plus (+) grade and subtract .33 for a minus (−) grade. Thus, a B+ yields a 3.33 whereas an A− yields a 3.67. [ 18 ] A-plusses, if given, are usually assigned a value of 4.0 (equivalent to an A) due to the common assumption that a 4.00 is the best possible grade-point average, although 4.33 is awarded ...

    In a problem-solving context, it can be used to formally represent a problem as a theorem to be proved, and to represent the knowledge needed to solve the problem as the premises to be used in a proof that the problem has a solution. The use of computers to prove mathematical theorems using formal logic emerged as the field of automated theorem ...

    en.wikipedia.org/wiki/Beta-propeller

    Four-bladed beta-propellers function mainly as transport proteins, and because of its structure, they have a conformation that is favorable for substrate binding. [4] Unlike larger beta-propellers, four-bladed beta-propellers usually cannot perform catalysis themselves, but act instead to aid in catalysis by performing the aforementioned functions.

    en.wikipedia.org/wiki/Regularized_least_squares

    Regularized least squares (RLS) is a family of methods for solving the least-squares problem while using regularization to further constrain the resulting solution. RLS is used for two main reasons. The first comes up when the number of variables in the linear system exceeds the number of observations.
