Numerical Quantum Field Theory on the Continuum and a New Look at Perturbation Theory

The Source Galerkin method finds approximate solutions to the functional differential equations of field theories in the presence of external sources. While developing this process, it was recognized that approximations of the spectral representations of the Green’s functions by Sinc function expansions are an extremely powerful calculative tool. Specifically, this understanding makes it not on...

A first look at blazars with BeppoSAX

The ”blazar phenomenon” is due to the presence of relativistic flows (jets) emanating from the nuclei of active galaxies which are radio loud. The power to energize the radio lobes is transported in the jets. Blazars are the subset of radio loud AGN for which the relativistic jet happens to point at small angles to the line of sight. Since the radiation emitted by the jet is relativistically be...

A first look at nurse editors' compensation.

While the compensation for many nursing roles is published and accessible, no data have heretofore been available on monetary compensation for nurse editors. Answers to questions about compensation contained in a 108-question international survey of 88 editors of nursing journals, which was designed to learn about all aspects of the role of editor, are described. This study provides a first loo...

A First Look at Differential Algebra

has no solutions which can be written using elementary functions, or anti-derivatives of elementary functions, or exponentials of such anti-derivatives, or anti-derivative of those, etc. We should note that Equation 1 can be solved using power series, integrals which depend on a parameter, or Bessel functions of order 1/3. However, as we will see, none of these methods of solution are “algebrai...

A first look at browser-based Cryptojacking

In this paper, we examine the recent trend towards in-browser mining of cryptocurrencies; in particular, the mining of Monero through Coinhive and similar codebases. In this model, a user visiting a website will download a JavaScript code that executes client-side in her browser, mines a cryptocurrency—typically without her consent or knowledge—and pays out the seigniorage to the website. Websi...
