CP violating phases in mu-e conversion
Experiments are planned to improve the sensitivity of mu-e conversion from
the current ~ 10^{-12} to 10^{-16} - 10^{-18}. If the muon (bound to the
nucleus) could be polarised, a spin asymmetry of the final state electron is
sensitive to CP violating phases on lepton flavour violating operators. This is
similar to extracting phases from asymmetries in the final state spin and phase
space distributions of mu to 3e and mu to e gamma.Comment: 4 pages, no figures, some typos correcte
Basis Independent Measures of R-parity Violation
We construct basis-independent expressions that measure the magnitude of
-parity breaking due to possible superpotential terms in the Minimal
Supersymmetric extension of the Standard Model, in the absence of soft
supersymmetry-breaking terms and spontaneous gauge symmetry breaking. We also
discuss briefly their application to a consistent treatment of cosmological
constraints on -parity violation.Comment: 13 pages, Late
Efficient homogenisation of photographic dispersions
The formation of fine droplets in a photographic emulsion which is forced through an orifice disperser consisting of a tube with one or more abrupt constrictions is considered. Some design ideas for reducing the droplet size are presented

Segment-level evaluation of the simulated aggregation test: US corn and soybean exploratory experiment
An evaluation of the corn and soybean proportion-estimation accuracy and dot labeling accuracy of the Simulated Aggregation Test, U.S. Corn and Soybean Exploratory Experiment, is presented. These results are in turn compared with the corn and soybean proportion-estimation accuracy and dot labeling accuracy of the Classification Procedures Verification Test

Search for Second and Third Generation Leptoquarks at CDF
We report the results of a search for second and third generation leptoquarks
using 88 of data recorded by the Collider Detector at Fermilab.
Color triplet technipions, which play the role of scalar leptoquarks, are
investigated due to their potential production in decays of strongly coupled
color octet technirhos. Events with a signature of two heavy flavor jets and
missing energy may indicate the decay of a second (third) generation leptoquark
to a charm (bottom) quark and a neutrino. As the data is found to be consistent
with Standard Model expectations, mass limits are determined.Comment: Talk given at DPF2000, Columbus (OH), 9-12 Aug 2000. 3 pages, 4

Addressing data management training needs: a practice based approach from the UK
In this paper, we describe the current challenges to the effective management and preservation of research data in UK universities, and the response provided by the JISC Managing Research Data programme.
This paper will discuss, inter alia, the findings and conclusions from data management training projects of the first iteration of the programme and how they informed the design of the second, paying particular attention to initiatives to develop and embed training materials
Genomic control of patterning
The development of multicellular organisms involves the partitioning of the organism into territories of cells of specific structure and function. The information for spatial patterning processes is directly encoded in the genome. The genome determines its own usage depending on stage and position, by means of interactions that constitute gene regulatory networks (GRNs). The GRN driving endomesoderm development in sea urchin embryos illustrates different regulatory strategies by which developmental programs are initiated, orchestrated, stabilized or excluded to define the pattern of specified territories in the developing embryo
The Top Priority: Precision Electroweak Physics from Low to High Energy
Overall, the Standard Model describes electroweak precision data rather well.
There are however a few areas of tension (charged current universality, NuTeV,
(g-2)_\mu, b quark asymmetries), which I review emphasizing recent theoretical
and experimental progress. I also discuss what precision data tell us about the
Higgs boson and new physics scenarios. In this context, the role of a precise
measurement of the top mass is crucial.Comment: 12 pages; invited talk at 21st International Symposium on Lepton and
