Uncertainty analysis of diffuse-gray radiation enclosure problems: A hypersensitive case study
An uncertainty analysis of diffuse-gray enclosure problems is presented. The genesis was a diffuse-gray enclosure problem which proved to be hypersensitive to the specification of view factors. This genesis is discussed in some detail. The uncertainty analysis is presented for the general diffuse-gray enclosure problem and applied to the hypersensitive case study. It was found that the hypersensitivity could be greatly reduced by enforcing both closure and reciprocity for the view factors. The effects of uncertainties in the surface emissivities and temperatures are also investigated

BSP implementation of the 2017 classification of periodontal diseases: a practice retrospective
Introduction The new world classification of periodontal diseases and conditions was developed in 2017. The British Society of Periodontology and Implant Dentistry (BSP) implemented the classification in a series of papers published in the British Dental Journal in January 2019.
Aims and objectives This study aimed to investigate if the BSP implementation was workable in general dental practice and to reveal if any lessons were learnt from its regular use two years following its release.
Materials and methods This was a cross-sectional, retrospective, non-intervention analysis of a patient population (n = 891) drawn from a complete list of a private dental surgeon. Diagnostic and demographic data were drawn from the patient records, collated and analysed using SPSS Statistics v26.
Results Diagnoses derived from the new classification were identified for 92% of subjects, indicating a high level of implementation. In total, 20.9% of subjects were diagnosed with periodontitis, and of these, 57% were unstable, 39% stable and 4% in remission. The mean bleeding on probing score across the cohort was 7.7%. Moreover, 76% of the non-periodontitis patients were diagnosed with 'clinical gingival health', 23% with localised gingivitis and 1% with generalised gingivitis.
Conclusion The new classification has been found to be readily implemented in a general practice setting. Use of the new classification allows for close monitoring of periodontal status, and as a result, close monitoring of the effectiveness of pathways of care
Old Stellar Populations of the Small Magellanic Cloud
We present WFPC2 and ground-based VI photometry of NGC 121 and a nearby field
in the outer SMC. For NGC 121, we measure a true distance modulus of (m-M)0 =
18.96 +/- 0.04 (distance of 61.9 +/- 1.1 kpc), age of 10.6 +/- 0.5 Gyr,
metallicity of [Fe/H] = -1.03 +/- 0.06, and initial mass of 4.1 +/- 0.4 x 10^5
Msun, assuming a Salpeter IMF with lower cutoff at 0.1 Msun. In the outer SMC
field, we find evidence of stars covering a wide range of ages -- from 2 Gyr
old to at least 9-12 Gyr old. We have measured the distance, extinction, and
star formation history (past star formation rates and enrichment history) using
a CMD fitting algorithm. The distance modulus of the SMC is measured to be
(m-M)0 = 18.88 +/- 0.08, corresponding to a distance of 59.7 +/- 2.2 kpc. The
overall star formation rate appears to have been relatively constant over this
period, although there may be small gaps in the star forming activity too small
to be resolved. The lack of current star-forming activity is a selection
effect, as the field was intentionally chosen to avoid recent activity. The
mean metallicity of this field has increased from an average of [Fe/H] = -1.3
+/- 0.3 for stars older than 8 Gyr to [Fe/H] = -0.7 +/- 0.2 in the past 3 Gyr.Comment: 29 pages, 14 figures accepted for publication in Ap

The NASA X-Ray Mission Concepts Study
The 2010 Astrophysics Decadal Survey recommended a significant technology development program towards realizing the scientific goals of the International X-ray Observatory (IXO). NASA has undertaken an X-ray mission concepts study to determine alternative approaches to accomplishing IXO's high ranking scientific objectives over the next decade given the budget realities, which make a flagship mission challenging to implement. The goal of the study is to determine the degree to which missions in various cost ranges from 2B could fulfill these objectives. The study process involved several steps. NASA released a Request for Information in October 2011, seeking mission concepts and enabling technology ideas from the community. The responses included a total of 14 mission concepts and 13 enabling technologies. NASA also solicited membership for and selected a Community Science Team (CST) to guide the process. A workshop was held in December 2011 in which the mission concepts and technology were presented and discussed. Based on the RFI responses and the workshop, the CST then chose a small group of notional mission concepts, representing a range of cost points, for further study. These notional missions concepts were developed through mission design laboratory activities in early 2012. The results of all these activities were captured in the final X-ray mission concepts study report, submitted to NASA in July 2012. In this presentation, we summarize the outcome of the study. We discuss background, methodology, the notional missions, and the conclusions of the study report
The Fermi GBM Gamma-Ray Burst Spectral Catalog: Four Years Of Data
In this catalog we present the updated set of spectral analyses of GRBs
detected by the Fermi Gamma-Ray Burst Monitor (GBM) during its first four years
of operation. It contains two types of spectra, time-integrated spectral fits
and spectral fits at the brightest time bin, from 943 triggered GRBs. Four
different spectral models were fitted to the data, resulting in a compendium of
more than 7500 spectra. The analysis was performed similarly, but not
identically to Goldstein et al. 2012. All 487 GRBs from the first two years
have been re-fitted using the same methodology as that of the 456 GRBs in years
three and four. We describe, in detail, our procedure and criteria for the
analysis, and present the results in the form of parameter distributions both
for the observer-frame and rest-frame quantities. The data files containing the
complete results are available from the High-Energy Astrophysics Science
Archive Research Center (HEASARC).Comment: Accepted for publication in ApJ
