Defined benefit pension plans are the predominant method of retirement compensation for state government employees. They create entitlements to annuities whose value is ...

Background: Better understanding of aortic root geometry could improve diagnosis and reconstruction of pathologic aortic valves. In this study, a previous model of ...

We describe a simple implementation of the Takagi factorization of symmetric matrices A=U L UT with unitary U and diagonal L e T, e >= 0 in terms of the square root of an ...

We present a Mathematica package for simulation of spectral-angular distributions and energy spectra of planar channeling radiation of relativistic electrons and positrons ...

We prove that nearest-neighbor percolation in dimensions d  11 displays mean-field behavior by proving that the infrared bound holds, in turn implying the finiteness of the ...

This textbook takes a broad yet thorough approach to mechanics, aimed at bridging the gap between classical analytic and modern differential geometric approaches to the ...

A new, very fast code, SSFPQL, which solves the steady state quasi-linear kinetic equation describing the ion distribution function during ion cyclotron heating in two ...

Currently there is a "reform" taking place in the teaching of beginning differential equations. Rather than focusing upon various types of equations and the techniques ...

In this article we discuss several principles and tools which should expedite description of the electrostatic potentials and electrostatic interactions of molecules, and ...

As Mathematica in Education acquires new capabilities with its electronic version this article shows how to link the color and sound capabilities of Mathematica to ...
