Quantum entanglement has been focus of fundamental debate since the original paper of Einstein, Podolsky and Rosen [1] and the work of Bell [2], discussing its implications on fundamental issues related to the concepts of physical reality and locality. It has only been during the last few years when it has been recognized that this feature of Quantum Mechanics may also have important applications in the fields of communication and computation. In particular, it has been shown that using entanglement would (...) allow to perform certain computational tasks, such as factoring, much faster. On the other hand, it provides the basis for provably secure secret communication and cryptography. (shrink)

The selfish goal metaphor is interesting and intriguing. It accounts for the idiosyncrasies and inconsistencies in peoples' goal pursuits without invoking free will, self-regulatory, or self-control failures. However, people pursue multiple goals, sometimes simultaneously. We argue that the model proposed in the target article may gain significant theoretical and practical value if the principles underlying goal selection and/or balancing on a moment-to-moment basis are clearly specified and integrated with the notion of the selfish goal.

It is demonstrated with the help of an example that in general one cannot derive a constant of motion from a conservation law even if one assumes that the field under consideration and all its derivatives with respect to the space coordinates vanish rapidly as the space coordinates tend to infinity.

A simple model of an exciton-phonon system is studied in connection with quantum chaos.

'Uncertainty and chance' is a subject with a broad span, in that there is no academic discipline or walk of life that is not beset by uncertainty and chance. In this book a range of approaches is represented by authors from varied disciplines: natural sciences, mathematics, social sciences and medical sciences. At one extreme, this volume is concerned with the foundations of probability. At the other extreme, we have scholars who acknowledge the concept of chance and uncertainty but do not (...) cope with it by means of systematic measurement or quantative analysis. (shrink)
