Correct ordering in the Zipf-Poisson ensemble
We consider a Zipf--Poisson ensemble in which X_i\sim\poi(Ni^{-\alpha}) for
and and integers . As the first
random variables have their proper order relative to each
other, with probability tending to 1 for up to
for an explicit constant . The
rate cannot be achieved. The ordering of the first
entities does not preclude for some interloping . The first
random variables are correctly ordered exclusive of any interlopers, with
probability tending to 1 if for . For
a Zipf--Poisson model of the British National Corpus, which has a total word
count of , our result estimates that the 72 words with the
highest counts are properly ordered
Empirical stationary correlations for semi-supervised learning on graphs
In semi-supervised learning on graphs, response variables observed at one
node are used to estimate missing values at other nodes. The methods exploit
correlations between nearby nodes in the graph. In this paper we prove that
many such proposals are equivalent to kriging predictors based on a fixed
covariance matrix driven by the link structure of the graph. We then propose a
data-driven estimator of the correlation structure that exploits patterns among
the observed response values. By incorporating even a small fraction of
observed covariation into the predictions, we are able to obtain much improved
prediction on two graph data sets.Comment: Published in at http://dx.doi.org/10.1214/09-AOAS293 the Annals of

Scoping Review of the development of artificial eyes throughout the years
Losing an eye following trauma can lead to profound psychosocial difficulties making it imperative for the wearer to be fitted with an aesthetically pleasing custom-made artificial eye. Despite recent technological advancements, current design and manufacturing processes have remained unchanged in over 55 years. With the aim of portraying current knowledge regarding the development of artificial eyes in order to aid future development, a scooping review was conducted. Six online search engines were used: Scopus, PubMed, MedLine Complete, Web of Science, Science Direct and Google Scholar. Thirty-eight articles met the inclusion criteria and underwent numerical and thematic analysis with three thematic themes emerging. History and the current process of artificial eyes has been well documented, however, the impact of wearing artificial eyes is sparse. On-going research and development into the design and manufacturing processes of artificial eyes and the psychosocial impact of wearing an artificial eye is needed

The importance of incorporating technological advancements into the artificial eye process: a perspective commentary
Application of technology into healthcare has typically been targeted to high demand illnesses and treatments. However, with an increasing need to meet patient’s expectations combined with increased accessibility and reduced costs, smaller healthcare fields are starting to investigate its function and usability. Services have historically been led by skills and expertise, and recent developments are being seen by ocularists in the field of prosthetic eyes who acknowledge the potential benefit from technological advancement. Utilising the technologies recently investigated in maxillofacial prosthesis can start the evolutionary process where products are continually re-designed and re-developed to achieve excellent patient outcome and satisfaction levels

Retinoblastoma: Identifying the Diagnostic Signs for Early Treatment
Retinoblastoma is a rare but significant cause of childhood eye cancer world-wide. The prognosis depends upon early diagnosis and treatment but also upon accurate classification of the tumours. Unilateral incidence is normally non-hereditary compared with bilateral incidence where secondary tumours are more common. Survivorship is much better for unilateral compared with bilateral and trilateral retinoblastoma. Early signs are important to detect and photography can assist in identifying no return of “red-eye” during flash photography and yellow appearance of the tumour. Treatment options are discussed together with new psycho-oncology approaches that address potential trauma in the survivor as well as in the family of the survivor

Combustion of hydrogen injected into a supersonic airstream (a guide to the HISS computer program)
A computer program based on a finite-difference, implicit numerical integration scheme is described for the prediction of hydrogen injected into a supersonic airstream at an angle ranging from normal to parallel to the airstream main flow direction. Results of calculations for flow and thermal property distributions were compared with 'cold flow data' taken by NASA/Langley and show excellent correlation. Typical results for equilibrium combustion are presented and exhibit qualitatively plausible behavior. Computer time required for a given case is approximately one minute on a CDC 7600. A discussion of the assumption of parabolic flow in the injection region is given which demonstrates that improvement in calculation in this region could be obtained by a partially-parabolic procedure which has been developed. It is concluded that the technique described provides an efficient and reliable means for analyzing hydrogen injection into supersonic airstreams and the subsequent combustion
