Innovations in Analyzing Manuscript Images and Using them in Digital Scholarly Publications
Evellum began developing software for the digital analysis and presentation of medieval manuscripts nearly fifteen year ago, when there were very few design and delivery options available to programmers. In the early years, it was not apparent how it would be best to deliver such products nor exactly how they would function and be used, and the question of longevity plagued us. Today there is the TEI to help standardize the mark-up of text and to offer a greater guarantee of longevity than was previously possible, and internet browsers are capable of facilitating the delivery of programmes that integrate text, image and video. Two products designed by Evellum are described here, with comments on the pedagogical issues that have helped determine their shape
Geographical variation in certification rates of blindness and sight impairment in England, 2008-2009
To examine and interpret the variation in the incidence of blindness and sight impairment in England by PCT, as reported by the Certificate of Vision Impairment (CVI).
Design:
Analysis of national certification data.
Setting:
All Primary Care Trusts, England.
Participants:
23â
773 CVI certifications issued from 2008 to 2009.
Main Outcome measures:
Crude and Age standardised rates of CVI data for blindness and sight loss by PCT.
Methods:
The crude and age standardised CVI rates per 100â
000 were calculated with Spearman's rank correlation used to assess whether there was any evidence of association between CVI rates with Index of Multiple Deprivation (IMD) and the Programme Spend for Vision.
Results:
There was high-level variation, almost 11-fold (coefficient of variation 38%) in standardised CVI blindness and sight impairment annual certification rates across PCTs. The mean rate was 43.7 and the SD 16.7. We found little evidence of an association between the rate of blindness and sight impairment with either the IMD or Programme Spend on Vision.
Conclusions:
The wide geographical variation we found raises questions about the quality of the data and whether there is genuine unmet need for prevention of sight loss. It is a concern for public health practitioners who will be interpreting these data locally and nationally as the CVI data will form the basis of the public health indicator âpreventable sight lossâ. Poor-quality data and inadequate interpretation will only create confusion if not addressed adequately from the outset. There is an urgent need to address the shortcomings of the current data collection system and to educate all public health practitioners
Possibility of "magic" trapping of three-level system for Rydberg blockade implementation
The Rydberg blockade mechanism has shown noteworthy promise for scalable
quantum computation with neutral atoms. Both qubit states and gate-mediating
Rydberg state belong to the same optically-trapped atom. The trapping fields,
while being essential, induce detrimental decoherence. Here we theoretically
demonstrate that this Stark-induced decoherence may be completely removed using
powerful concepts of "magic" optical traps. We analyze "magic" trapping of a
prototype three-level system: a Rydberg state along with two qubit states:
hyperfine states attached to a J=1/2 ground state. Our numerical results show
that, while such a "magic" trap for alkali metals would require prohibitively
large magnetic fields, the group IIIB metals such as Al are suitable
candidates.Comment: 5 pages, 3 figure
Possibility of "magic" co-trapping of two atomic species in optical lattices
Much effort has been devoted to removing differential Stark shifts for atoms
trapped in specially tailored "magic" optical lattices, but thus far work has
focused on a single trapped atomic species. In this work, we extend these ideas
to include two atomic species sharing the same optical lattice. We show
qualitatively that, in particular, scalar J = 0 divalent atoms paired with
non-scalar state atoms have the necessary characteristics to achieve such Stark
shift cancellation. We then present numerical results on "magic" trapping
conditions for 27Al paired with 87Sr, as well as several other divalent atoms.Comment: 5 pages, 2 figures, 1 tabl

A study of the dielectric constant of bound water
It is the purpose of this thesis to show that a study
of the dielectric loss properties of water adsorbed upon a
mineral may yield information concerning the properties of
'bound' water, by which is meant adsorbed water bonded so
strongly to a surface that it does not exhibit the normal
properties of water in bulk
