Abstract: Results on the determination of the interval within which the coefficients of a globally positive multivariate polynomial might fluctuate without altering the positivity property are given.

In this paper we introduce a Python package designed to aid in the analysis of differences in large spatio-temporal datasets, such as those produced by global climate models. While the new package is ...

A quadratic polynomial regression model was developed to assess the non-linear ... The improved fit over a linear model (as shown by BIC) reflects the mathematical characteristics of the dataset ...

pwtools is a Python package for pre- and postprocessing of atomistic calculations, mostly targeted to Quantum Espresso, CPMD, CP2K and LAMMPS. It is almost, but not quite, entirely unlike ASE, with ...
