Natural transformations

1992
Abstract Given a parallel pair of functors F, G: A→B, a natural transformation from F to G is a family of arrows vA: FA→ GA, one for each object A of A, such that for every arrow f: A→ A' of A the following square commutes: Suppose that A is Cartesian closed and take any object A of A.

Natural transformation in river epilithon

Applied and Environmental Microbiology, 1996
Natural transformation was demonstrated in unenclosed experiments incubated in river epilithon. Strains of Acinetobacter calcoaceticus were transformed to prototrophy by either free DNA (lysates) or live donor cells. The sources of transforming DNA and recipient culture were immobilized on filters, secured to stones, and incubated midstream in the ...

An investigation of the nature of parameterization for the Hough transform

Pattern Recognition, 1996
A novel parameterization method for the Hough transform is reported. Instead of the conventional non-parametric form, the parametric form is used and copies of the transformed shape are plotted on two-dimensional slices of the Hough space. It is shown that the corresponding parameterization has uniform precision with respect to translation, and cancels

On the Nature of Oncogenic Transformation of Cells

1981
Publisher Summary This chapter presents a class of genes in the genome of higher cells, which is called “growth genes.” The existence of the growth genes in multiplicity in a genome is envisaged as necessitated by the participation of each growth gene in a distinct pathway or related pathways of differentiation.

Transformations of Natural Law

2016
Abstract This chapter examines the transformation of ideas about international power that took place in the idiom of natural law between 1648 and 1815, a key period of early Western modernity. Pressed in part by external events and in part by developments in the relations between the Holy Roman Empire’s constituent units, university ...
