Penning t raps are very useful experimental devices wherever high precision measurements require spatial confinement of charged particles over prolonged periods of time. (For general reviews see [1] and [2].) Some experiments are done with single (or very few) particles, but usually one has to deal with a low density cloud of charged particles containing on the order of 10 to 10 particles. The ...

[1] Abstract: We propose that across-arc differences in the geochemistry of Izu-Bonin arc magmas are controlled by the addition of fertile-slab fluids to depleted mantle at the volcanic front, and residual-slab fluids to fertile mantle in the back arc without slab melting or contemporaneous back arc spreading. The arc consists of a volcanic front, an extensional zone, and seamount chains (the W...

In recent years, many interesting results have been reported by investigators a t tempt ing to identify antigen receptors on T cells, but there has been limited success in the characterization of these molecules. Most efforts have focused on T cells or T cell products that have been demonstrated to bind free antigen (Ag), because in these cases an easily definable function could be used to assa...

In this paper an a t tempt is made to find an answer to the question, "What is the most advantageous size for the retention limit of a risk portfolio, given the fact that a certain stability requirement is to be satisfied ?" This problem will be approached from the viewpoint of an insurer who wishes to obtain a certain degree of stability at lowest cost. I t is assumed that in his choice of rei...

I have been asked to discuss for you some applications of the Rayleigh-Ritz method in physics. Rather than at tempt to survey the whole of a discouragingly large field I have preferred to restrict my attention to some few topics from the theory of atomic and molecular structure. The application of the Rayleigh-Ritz method in this field has been carried out with some care and persistence, and th...

compensation. The guideline states, “The witness should receive compensation that is appropriate to his or her expertise and qualifications. Acceptance of a fee that is disproportionate to those customary for such professional endeavors is improper and unethical. . . . ‘ Unfortunately, since many lawyers and legal firms have difficulty obtaining physicians, they often tempt physicians by their ...

This paper presents the first laboratory study of risk-sharing without commitment. Our experiment captures the main features of a simple model of voluntary insurance between two agents. In the model, two individuals interact over a potential infinite horizon and suffer random income shocks. Risk-averse individuals have incentives to smooth consumption by making transfers to each other. These tr...

Crown gall, a neoplastic disease of plants, is of interest because the inciting bacterium, Agrobacterium tumefaciens (Smith and Town.) Conn, converts normal plant cells to tumor cells in short periods of time. Once the cellular alteration has been accomplished, the continued abnormal proliferation of the affected host cells becomes completely independent of the inciting organism. These findings...
