The Richardson–Lucy algorithm, also known as Lucy–Richardson deconvolution, is an iterative procedure for recovering an underlying image that has been blurred by a known point spread function. It was named after William Richardson and Leon B. Lucy , who described it independently.
Richardson married Margaret White Peirson in July 1879; they had six children. The six children were Edward Peirson, Mary Tuckerman, Maurice Howe, Henry Barber, Margaret, and Wyman Richardson. [7] The eldest son Edward Peirson Richardson (1881–1944) became a noted physician and father of the lawyer Elliot Richardson. Mary Tuckerman Richardson ...
[citation needed] Vesalius described a variety of hooks and retractors in the 16th century. [citation needed] Jan Mikulicz-Radecki's invention of a hinged rib spreading retractor in 1904 prompted a flurry of development of retractors in the early 20th century, culminating in 1936 in our modern device based on the design of Enrique Finochietto.

A continuous map : [,] is a deformation retraction of a space X onto a subspace A if, for every x in X and a in A, (,) =, (,), (,) =.In other words, a deformation retraction is a homotopy between a retraction and the identity map on X.
The generalized logistic function or curve is an extension of the logistic or sigmoid functions. Originally developed for growth modelling, it allows for more flexible S-shaped curves. The function is sometimes named Richards's curve after F. J. Richards, who proposed the general form for the family of models in 1959.

Modified Richardson iteration is an iterative method for solving a system of linear equations. Richardson iteration was proposed by Lewis Fry Richardson in his work dated 1910. It is similar to the Jacobi and Gauss–Seidel method. We seek the solution to a set of linear equations, expressed in matrix terms as
