INTRODUCTION The reproducibility of results is one of the underlying principles of science.
An observation can only be accepted by the scientific community when it can be confirmed …

This extensively revised edition of this popular text deals with the problems and issues
facing entrepreneurs and small business today. It now includes: a number of new …

The potentially hard oxides ZrO 2 and HfO 2 are investigated using ab initio electronic
structure calculations and structural properties of the lowest phases compared. In general …

The enigmatic interplay between electronic and magnetic phenomena observed in many
early experiments and outlined in Maxwell's equations propelled the development of …

A new parameter-free approximation for the exchange-correlation kernel f xc of time-
dependent density-functional theory is proposed. This kernel is expressed as an algorithm in …

Time-dependent density functional theory (TDDFT) is implemented in an all electron solid-
state code for the case of fully unconstrained noncollinear spins. We use this to study …

economic performance in Great Britain: 1977–1991, Reg. Studies 30, 31–40. Movements in …

The free energy principle, an influential framework in computational neuroscience and
theoretical neurobiology, starts from the assumption that living systems ensure adaptive …

Reduced density matrix functional theory for the case of solids is presented and an
exchange-correlation functional based on a fractional power of the density matrix is …

Laser pulses induce spin-selective charge flow that we show to generate dramatic changes
in the magnetic structure of materials, including a switching of magnetic order from …
