Back to the Future with Higher Ed: A Sample of Drupal Sites at UGA
Consisting of a show and tell of a selection of large and small site installations from various departments, schools and colleges at the University of Georgia, panelists including back end and front end developers, public relations experts, librarians, and web coordinators will share their ship\u27s timeline with Drupal versions and examples from the past, present and future. A moderator will then ask questions of panelists including: the biggest challenges they have faced with migrations and upgrades, the issues or blessings of more cohesive branding initiatives over the last few years, and their visions, concerns, and hopes for the future. In a post pandemic world, everyone contributes to digital content creation and curation. What is the shifting and evolving landscape of open source web development in higher ed? We hope for a vibrant segment of questions and look forward to engaging discussions. This session will be accessible to those new to Drupal as well as experts. This session will give an overview of Drupal websites at UGA, and compare that to the other site installs (both paid and open source) across campus. Attendees will walk away having learned a variety of different uses from small internal sites to large scale implemebtations in higher ed (intranets, student portals, faculty and research sites, libraries, and entire school websites).
The site-specific examples will be sure to inspire attendees, and the questions and answers to encourage a collaborative discussion to include sharing trouble-shooting tips and give rise to ideas or solutions. Panelists come from the University Libraries, Franklin College of Arts & Sciences, the School of Law & Law Library, and a moderator from Terry College of Business
An investigation of susceptibility loci in benign, aggressive and primary progressive mutiple sclerosis in Northern Irish population
Coherent Population Trapping of Electron Spins in a Semiconductor
In high-purity n-type GaAs under strong magnetic field, we are able to
isolate a lambda system composed of two Zeeman states of neutral-donor bound
electrons and the lowest Zeeman state of bound excitons. When the two-photon
detuning of this system is zero, we observe a pronounced dip in the
excited-state photoluminescence indicating the creation of the coherent
population-trapped state. Our data are consistent with a steady-state
three-level density-matrix model. The observation of coherent population
trapping in GaAs indicates that this and similar semiconductor systems could be
used for various EIT-type experiments.Comment: 5 pages, 4 figures replaced 6/25/2007 with PRL versio

Experimental demonstration of a classical analog to quantum noise cancellation for use in gravitational wave detection
We present results that are a classical analog to quantum noise cancellation. It is possible to breach the standard quantum limit in an interferometer by the use of squeezing to correlate orthogonal quadratures of quantum noise, causing their effects on the resulting sensitivity to cancel. A laser beam incident on a Fabry-Perot cavity was imprinted with classical, correlated noise in the same quadratures that cause shot noise and radiation pressure noise. Couplings between these quadratures due to a movable mirror, sensitive to radiation pressure, cause the excess classical noise to cancel. This cancellation was shown to improve the signal to noise ratio of an injected signal by approximately a factor of 10
Hyperfine splittings in the system
Recent measurements of the , the ground state of the
system, show the splitting between it and the \Up(1S) to be 69.53.2 MeV,
considerably larger than lattice QCD and potential model predictions, including
recent calculations published by us. The models are unable to incorporate such
a large hyperfine splitting within the context of a consistent description of
the energy spectrum and decays. We demonstrate that in our model, which
incorporates a relativistic kinetic energy term, a linear confining term
including its scalar-exchange relativistic corrections, and the complete
one-loop QCD short distance potential, such a consistent description, including
the measured hyperfine splitting, can be obtained by not softening the delta
function terms in the hyperfine potential. We calculate the hyperfine splitting
to be 67.5 MeV.Comment: 5 pages, 3 tables, text revision
Squeezing in the audio gravitational wave detection band
We demonstrate the generation of broad-band continuous-wave optical squeezing
down to 200Hz using a below threshold optical parametric oscillator (OPO). The
squeezed state phase was controlled using a noise locking technique. We show
that low frequency noise sources, such as seed noise, pump noise and detuning
fluctuations, present in optical parametric amplifiers have negligible effect
on squeezing produced by a below threshold OPO. This low frequency squeezing is
ideal for improving the sensitivity of audio frequency measuring devices such
as gravitational wave detectors.Comment: 5 pages, 6 figure
Mastering the Master Space
Supersymmetric gauge theories have an important but perhaps under-appreciated
notion of a master space, which controls the full moduli space. For
world-volume theories of D-branes probing a Calabi-Yau singularity X the
situation is particularly illustrative. In the case of one physical brane, the
master space F is the space of F-terms and a particular quotient thereof is X
itself. We study various properties of F which encode such physical quantities
as Higgsing, BPS spectra, hidden global symmetries, etc. Using the plethystic
program we also discuss what happens at higher number N of branes. This letter
is a summary and some extensions of the key points of a longer companion paper
