Bowling maidens over: 1931 and the beginnings of women's cricket in a Yorkshire town
This article focuses on the development of women's cricket in a West Yorkshire town - Brighouse - in the 1930s. It situates this subject within the context of the growth of women's cricket more generally, and goes on to explore the personality and uniqueness of women's cricket in the town. The article identifies key issues in the way that women's cricket was perceived at the time, particularly in the pages of the Brighouse & Elland Echo, the local newspaper. As such, it considers the novelty of the sport, the gender stereotyping that was an important aspect of newspaper coverage, the relationship between women's and men's cricket, and also the marketing of key fixture

The Improvement Program in Nonrelativistic Lattice QCD
Progress in the improvement program in nonrelativistic lattice QCD is
outlined. The leading radiative corrections to the heavy-quark mass
renormalization, energy shift, and two important kinetic coupling coefficients
are presented. The reliability of tadpole-improved perturbation theory in
determining the energy shift and mass renormalization is demonstrated.Comment: 3 pages in uuencoded-compressed-PostScript format, to appear in the

Decoherence-free quantum-information processing using dipole-coupled qubits
We propose a quantum-information processor that consists of decoherence-free
logical qubits encoded into arrays of dipole-coupled qubits. High-fidelity
single-qubit operations are performed deterministically within a
decoherence-free subsystem without leakage via global addressing of bichromatic
laser fields. Two-qubit operations are realized locally with four physical
qubits, and between separated logical qubits using linear optics. We show how
to prepare cluster states using this method. We include all
non-nearest-neighbor effects in our calculations, and we assume the qubits are
not located in the Dicke limit. Although our proposal is general to any system
of dipole-coupled qubits, throughout the paper we use nitrogen-vacancy (NV)
centers in diamond as an experimental context for our theoretical results.Comment: 7 pages, 5 figure
The Heavy Quark Self-Energy in Nonrelativistic Lattice QCD
The heavy quark self-energy in nonrelativistic lattice QCD is calculated to
in perturbation theory. An action which includes all
spin-independent relativistic corrections to order , where is the
typical heavy quark velocity, and all spin-dependent corrections to order
is used. The standard Wilson action and an improved multi-plaquette action are
used for the gluons. Results for the mass renormalization, wavefunction
renormalization, and energy shift are given; tadpole contributions are found to
be large. A tadpole improvement scheme in which all link variables are rescaled
by a mean-field factor is also studied. The effectiveness of this scheme in
offsetting the large tadpole contributions to the heavy quark renormalization
parameters is demonstrated.Comment: 28 pages, SLAC-PUB-598
