A series of range modulator wheels has been developed to modify the Bragg peak of the 160 MeV proton beam at the Harvard Cyclotron Laboratory. Flat depth-dose distributions up to 15 cm in extent have been produced. Ease of construction ...

To count the number of periodic points ofu(x) brings in very delicate questions about automorphisms of local fields. Using the ideas developed here, we shall give another short proof of Sen's Theorem. We also give an upper bound for the...

This article looks at biotechnology as an emerging technology and whether the optimism generated about it is justified. It discusses whether biotechnology is capable of changing the technological paradigm, and looks at future hopes for ...

A measure of complexity based on a probabilistic description of physical systems is proposed. This measure incorporates the main features of the intuitive notion of such a magnitude. It can be applied to many physical situations and to ...

Reduction of spatial symmetry can remove the degeneracy of energy levels in quantum mechanics. The Womens Nike Shoes break of time-reversal symmetry by inclusion of a dissipative environment can have a similar effect. The corresponding ...

In a model of many goods and countries with specific tariffs and subsidies, the paper proves that a proportional reduction (a radial contraction) of all tariff/subsidy rates improves the world's potential welfare. This generalizes a res...

Using suitable conditions of weak commutativity, we prove theorems for a pair of Nike Shox Women nonself mappings which generalize earlier results due to Rhoades and Assad et al. Some illustrative examples and applications are also disc...

An occasional verse written on Sept. 30, 2003 by Alex Henney, with assistance from people of likeminded ilk, to commemorate the move of Ofgem’s Director-General, Mens Nike Shox Clearance Callum McCarthy, to a new post as Chairman of t...

The standard Clough-Tocher split-domain scheme constructs a surface element with quadratic precision. In this paper, I will look at methods for improving the degrees of freedom in Clough-Tocher schemes. In particular, I will discuss mod...

The discrete variable minimum problem inherent in the determination of the March-Young coefficients for the Fermi term of the three-dimensional TFW equation is solved approximately by a computer iteration procedure. In general, the mini...
