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.

From the Arrow of Time to the Arrow of Life
Earth, Moon, and Planets, 2006Astrobiology, like many (but not all) sciences, must take into account questions of the “Why?”, “Where?”, “How?” and “When?” type. In this introductory chapter, we explain why, in this book, we will only consider two of these questions that are, moreover, deeply interrelated. Chronology is by definition related to the “when?” question but as soon as we

Arrow-arrow correlations for the six-vertex model
Physical Review E, 2013The six-vertex model on a square lattice is "exactly solvable" because an exact formula for the free energy can be obtained by the Bethe ansatz. However, exact formulas for the correlations of local bulk observables, such as the orientation of the arrow at a given edge, are, in general, not available.

A drive-by download attack occurs when a user visits a webpage which attempts to automatically download malware without the user's consent. Attackers sometimes use a malware distribution network (MDN) to manage a large number of malicious webpages, exploits, and malware executables.

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

Arrows Pointing at Arrows: Arrow Logic, Relevance Logic, and Relation Algebras
2014Richard Routley and Robert K. Meyer introduced a ternary relational semantics for various relevance logics in the early 1970s. Johan van Benthem and Yde Venema introduced “arrow logic” in the early 1990s and about the same time I showed how a variation of the Routley–Meyer semantics could be used to provide an interpretation of Tarski’s axioms for ...
