It is well-known that a classical point charge in 1+1 D hyperbolic motion in space and time is reaction-free. But this is a special case of a larger set of reaction-free trajectories that in general are curved paths through space, i.e. in 2+1 D. This note catalogs the full family of reaction-free trajectories, giving a geometrical interpretation by which means the curved path possibility is eas...

This article discusses the relationship between the divine promises in the Abraham narrative and the use made by this Old Testament material in the New Testament. It is argued that the New Testament's reinterpretation of the Abrahamic Covenant (e.g. relating the promise of blessing to the Gospel of Jesus Christ and applying the promise of multitudinous descendants to the Christian Church) is fu...

Eilon Solan (Tel-Aviv University) Stopping Games with Termination Rates Multiplayer stopping game with termination rates are continuous-time stopping games in which when some players stop at the time interval [t,t+dt), the game does not terminate with probability 1, but rather stops with some probability, which is of the order of dt and may depend on time and on the set of players who stop at t...

Distance-based learning methods, like clustering and SVMs, are dependent on good distance metrics. This paper does unsupervised metric learning in the context of clustering. We seek transformations of data which give clean and well separated clusters where clean clusters are those for which membership can be accurately predicted. The transformation (hence distance metric) is obtained by minimiz...

Climatic and subsequent habitat change has often been invoked as a driving force of evolutionary change in hominins, mammals, and other taxa (Vrba 1988a, 1988b, 1992, 1995; Bromage & Schrenk 1999; Potts 1998; Bobe & Eck 2001; Janis et al. 2002). Global climatic change in the mid Pliocene Epoch has been suggested as a cause for hominin speciation events (Vrba 1995) and is correlated with changes...
