There is a large body of evidence to suggest that the anomalous OH emission sources—particularly those which are classified as class I sources—are associated with protostars. It is also known, from the theories brought forward over the past four years, that maser action can be caused by quite a variety of non-equilibrium situations. It is argued here that one particular kind of non-equilibrium situation which can plausibly be expected to exist in protostars is very similar to that proposed previously in the electron-pumping model, and that, in this new context, it can mimic most of the observed features of class I sources.

AbstractThe out-of-equilibrium situation in which an initially sharp-edged cylindrical electron beam, that could, e.g., model electrons flowing within a wire, is injected into a plasma is considered. A detailed computation of the subsequently produced magnetic field is presented. The control parameter of the problem is shown to be the ratio of the beam radius to the electron skin depth. Two alternative ways to address analytically the problem are considered: one uses the usual Laplace transform approach, the other one involves Riemann's method in which causality conditions manifest through some integrals of triple products of Bessel functions.

In this chapter, Ober and Weingast find the roots of some of the most unusual features of Archaic/Classical-era Sparta in the “proportionality principle.” That principle holds that the stability of a regime in which ruling elites extract revenues from nonelites through violence (or its threat) requires that each elite receive a share of rents proportionate to his potential to employ disruptive violence. When proportionality is respected, no one with the power to disrupt society has an incentive to do so. This equilibrium situation helps explain the high degree of stability in Sparta’s sociopolitical system, but it also held the seeds of Sparta’s demise. Proportionality meant that rents could not be redistributed in ways that would have been more economically productive, and the Spartans’ failure to redistribute rents led to the regular demotion of the least successful Spartiates from the ruling class and hence to demographic and military collapse.

ABSTRACTThe formation of a continuous metallic layer in the doped region of LiF crystals implanted at low temperature, has been explained by the formation of bridges between next neighbouring alkali ions of the lattice around-each implanted ion. For a critical concentration of implanted ions it is possible to show using statistical arguments that conducting chains are formed by the union of these links, according to a percolation mechanism. We show that the assumption of a distribution of isolated implanted ions at low temperature is justified by the observation of their precipitation when the crystal is warmed up to room temperature. The transformation of the metallic optical absorption into the colloidal band associated with precipitates of implanted ions is correlated with the transition from a conducting state to an insulating state of the implanted layer. We show that this evolution towards an equilibrium situation may be reversed by a reirradiation, which is used as an external perturbation and that the conducting state associated with dispersed implanted ions is then once again obtained.

The World

This paper attempts to put the present mutation of the world economy in historical perspective. It uses a meso-analytical framework to examine the economic transformation we are experiencing. The main force at work, it is claimed, is a progressive dematerialization of economic activity which has triggered a reorganization of the world economy as instituted process. The extent to which a new international industrial order is in the making is examined together with the forces at work to transform the present conflictive equilibrium situation into a situation of creative disequilibrium.

Noncooperative Differential Games

A linear-quadratic positional differential game of N persons is considered. The solution of a game in the form of Nash equilibrium has become widespread in the theory of noncooperative differential games. However, Nash equilibrium can be internally and externally unstable, which is a negative in its practical use. The consequences of such instability could be avoided by using Pareto maximality in a Nash equilibrium situation. But such a coincidence is rather an exotic phenomenon (at least we are aware of only three cases of such coincidence). For this reason, it is proposed to consider the equilibrium of objections and counterobjections. This article establishes the coefficient criteria under which in a differential positional linear-quadratic game of N persons there is Pareto equilibrium of objections and counterobjections and at the same time no Nash equilibrium situation; an explicit form of the solution of the game is obtained.

Storage Properties

This contribution is concerned with the control parameters for arriving at defined, electrochemically relevant materials. The treatment is precise as far as the equilibrium situation of simple crystals is concerned, but becomes more and more qualitative if the distance from equilibrium or the (structural or compositional) complexity increases. It proves useful to distinguish between in situ parameters and ex situ parameters, the number ratio of which decreases with increasing distance from equilibrium. A particularly complex situation is met if not only size, shape and phase distribution are important, but even morphological details are of relevance, as it is the case for modern battery electrodes (“electrochemical integrated circuits”). For such cases archetypical examples along with their advantages or disadvantages for electrochemical storage properties are discussed. In this context, special emphasis is placed upon the dimensionality and distribution topology of building elements.

Patrolling Game

Many of us will have seen uniformed guards patrolling in museums, airports, and other places where thefts or attacks are possible. In other similar places, we may have been unaware of undercover agents carrying out similar patrols. The latter type of patrollers has been modeled in recent literature. However, when the patroller is visible (wears a uniform), the potential thief or terrorist may be able to spot him when he is nearby and to time his theft appropriately. For example, the thief may wait a specified time after the uniformed patroller leaves his area. In “The Uniformed Patroller Game,” Steve Alpern, Paul Chleboun, Stamatios Katsikas, and Kyle Y. Lin study the effect on the patrolling game of having a visible (uniformed) patroller. It turns out that putting a uniform on the patroller greatly reduces his effectiveness in intercepting thefts or attacks. Of course, the visibility of a uniform may act as a deterrent to having the theft take place at all.
