Possible highT c superconductivity in the Ba?La?Cu?O system

Contracted Gaussian basis sets for molecular calculations. I. Second row atoms, <i>Z</i>=11–18

Contracted Gaussian basis sets for molecular calculations are derived from uncontracted (12,8) and (12,9) sets for the neutral second row atoms, Z=11–18, and for the negative io...

On the implementation of an interior-point filter line-search algorithm for large-scale nonlinear programming

Highly dynamic Destination-Sequenced Distance-Vector routing (DSDV) for mobile computers

An ad-hoc network is the cooperative engagement of a collection of Mobile Hosts without the required intervention of any centralized Access Point. In this paper we present an in...

Modeling by shortest data description

Roothaan-Hartree-Fock atomic wavefunctions

Mixed-state entanglement and quantum error correction

Entanglement purification protocols (EPP) and quantum error-correcting codes (QECC) provide two ways of protecting quantum states from interaction with the environment. In an EP...

The Design and Implementation of FFTW3

FFTW is an implementation of the discrete Fourier transform (DFT) that adapts to the hardware in order to maximize performance. This paper shows that such an approach can yield ...

Gaussian-Type Functions for Polyatomic Systems. I

In view of rapid progress of computer capability, it is very desirable to have a reliable assessment of the usefulness of Gaussian-type orbitals as basis functions for large-sca...
