We study the critical energy and magnetization profiles for the Ising quantum chain with a marginal extended surface perturbation of
We consider the influence on the surface critical behaviour of a quantum Ising chain of quenched random surface perturbations decaying
We present an analysis of Hipparcos astrometric measurements of Upsilon Andromedae, a nearby main-sequence star around which three planet candidates
A toy model of a neural network in which both Hebbian learning and reinforcement learning occur is studied. The problem
An ensemble approach for force networks in static granular packings is developed. The framework is based on the separation of
In a previous paper, we have described a method to perform Fixed-Node Quantum Monte Carlo calculations for lattice fermions. In
This paper gives an introduction to the Keldysh formalism, with emphasis on its usefulness in time-dependent density functional theory. In
Several recent papers conclude that radio-pulsar magnetic fields decay on a time-scale of 10 Myr, apparently contradicting earlier results. We
We consider an arbitrarily charged polymer driven by a weak field through a gel according to the rules of the
This contribution is intended as a `rough guide' to the Hipparcos Catalogue for the non-expert user. Some general aspects of
Hipparcos trigonometrical parallaxes of Mira-type variables have been combined with ground-based angular diameter measurements to derive linear diameters. Of eight

Using the 2dF multi-fibre instrument at the AAT, we have carried out a spectroscopic survey of over 1500 stars brighter
The effectiveness of the recently developed Fixed-Node Quantum Monte Carlo method for lattice fermions, developed by van Leeuwen and co-workers,
