The time symmetry of the physical laws is discussed. The asymmetry in all statistical processes is found to be related to the tendency for radiation to diverge and that in turn is related to the expansion of the universe. No asymmetry is contained in the laws of electrodynamics, and the choice of the retarded potentials is not a time unsymmetrical step.

Consider this simple Haskell definition, of a function which counts the number of occurrences of a given word w in a string: count w = length . filter (==w) . words This is an example of “point-free” programming style, where we build a function by composing others, and make heavy use of higher-order functions such as filter.

We study a number of embedded DSLs for autonomous ordinary differential equations (autonomous ODEs) in Haskell. A naive implementation based on the lazy tower of derivatives is straightforward but has serious time and space leaks due to the loss of sharing when handling cyclic and infinite data structures.

Meniscus arrow in meniscal arrow.
Surgical technology international, 2012The meniscus arrow is a T-shaped fastener that provides an "all inside" technique for repair of longitudinal meniscal tears in the vascular zone through arthroscopic portals. No posterior incisions are needed and there are no sutures to tie. The arrow is made of proprietary self-reinforced polylactic acid and is rigid enough to allow impaction across a

A modal theory of arrows. Arrow logics I
2005The notion of arrow structure /a.s./ is introduced as an algebraic version of the notion of directed multi graph. By means of a special kind of a representation theorem for arrow structures it is shown that the whole information of an a.s. is contained in the set of his arrows equipped with four binary relations describing the four possibilities for ...
