Street, R. A.,Choi, J.-Y.,Tsapras, Y.,Han, C.,Furusawa, K.,Hundertmark, M.,Gould, A.,Sumi, T.,Bond, I. A.,Wouters, D.,Zellem, R.,Udalski, A.,Snodgrass, C.,Horne, K.,Dominik, M.,Browne, P.,Kains, N.,Br IOP Publishing 2013 The Astrophysical journal Vol.763 No.1

<P>We present an analysis of the anomalous microlensing event, MOA-2010-BLG-073, announced by the Microlensing Observations in Astrophysics survey on 2010 March 18. This event was remarkable because the source was previously known to be photometrically variable. Analyzing the pre-event source light curve, we demonstrate that it is an irregular variable over timescales >200 days. Its dereddened color, (V - I)(S),(0), is 1.221 +/- 0.051 mag, and from our lens model we derive a source radius of 14.7 +/- 1.3 R-circle dot, suggesting that it is a red giant star. We initially explored a number of purely microlensing models for the event but found a residual gradient in the data taken prior to and after the event. This is likely to be due to the variability of the source rather than part of the lensing event, so we incorporated a slope parameter in our model in order to derive the true parameters of the lensing system. We find that the lensing system has a mass ratio of q = 0.0654 +/- 0.0006. The Einstein crossing time of the event, t(E) = 44.3 +/- 0.1 days, was sufficiently long that the light curve exhibited parallax effects. In addition, the source trajectory relative to the large caustic structure allowed the orbital motion of the lens system to be detected. Combining the parallax with the Einstein radius, we were able to derive the distance to the lens, D-L = 2.8 +/- 0.4 kpc, and the masses of the lensing objects. The primary of the lens is an M-dwarf with M-L,M-1 = 0.16 +/- 0.03 M-circle dot, while the companion has M-L,M-2 = 11.0 +/- 2.0 M-J, putting it in the boundary zone between planets and brown dwarfs.</P>

Printed Polymer and a-Si TFT Backplanes for Flexible Displays

Street, R.A.,Wong, W.S.,Ready, S.E.,Chabinyc, M.L.,Arias, A.C.,Daniel, J.H.,Apte, R.B.,Salleo, A.,Lujan, R.,Ong, Beng,Wu, Yiliang The Korean Infomation Display Society 2005 Journal of information display Vol.6 No.3

The need for low cost, flexible, thin film transistor (TFT) display backplanes has focused attention on new processing techniques and materials. We report the development of TFT backplane technology based entirely on jet-printing, using a combination of additive and subtractive processing, to print active materials or etch masks. The technique eliminates the use of photolithography and has the potential to reduce the array manufacturing cost. The printing technique is demonstrated with both amorphous silicon and polymer semiconductor TFT arrays, and we show results of small prototype displays.

Beating Obesity: Factors Associated with Interest in Workplace Weight Management Assistance in the Mining Industry

Street, Tamara D.,Thomas, Drew L. Occupational Safety and Health Research Institute 2017 Safety and health at work Vol.8 No.1

Background: Rates of overweight and obese Australians are high and continue to rise, putting a large proportion of the population at risk of chronic illness. Examining characteristics associated with preference for a work-based weight-loss program will enable employers to better target programs to increase enrolment and benefit employees' health and fitness for work. Methods: A cross-sectional survey was undertaken at two Australian mining sites. The survey collected information on employee demographics, health characteristics, work characteristics, stages of behavior change, and preference for workplace assistance with reaching a healthy weight. Results: A total of 897 employees participated; 73.7% were male, and 68% had a body mass index in the overweight or obese range. Employees at risk of developing obesity-related chronic illnesses (based on high body mass index) were more likely to report preference for weight management assistance than lower risk employees. This indicates that, even in the absence of workplace promotion for weight management, some at risk employees want workplace assistance. Employees who were not aware of a need to change their current nutrition or physical activity behaviors were less likely to seek assistance. This indicates that practitioners need to communicate the negative effects of excess weight and promote the benefits of a healthy lifestyle to increase the likelihood of weight management. Conclusion: Weight management programs should provide information, motivation. and trouble-shooting assistance to meet the needs of at-risk mining employees, including those who are attempting to change and maintain behaviors to achieve a healthy weight and be suitably fit for work.

<P>We report the detection of a cold Neptune m(planet) = 21 +/- 2M(circle plus) orbiting a 0.38M(circle dot) M dwarf lying 2.5-3.3 kpc toward the Galactic center as part of a campaign combining ground-based and Spitzer observations to measure the Galactic distribution of planets. This is the first time that the complex real-time protocols described by Yee et al., which aim to maximize planet sensitivity while maintaining sample integrity, have been carried out in practice. Multiple survey and follow. up teams successfully combined their efforts within the framework of these protocols to detect this planet. This is the second planet in the Spitzer Galactic distribution sample. Both are in the near. to. mid-disk and are clearly not in the Galactic bulge.</P>

A Study on Theme of Attitudes

Barbara Streets,Yong Deuk Choi 한국노인복지학회 2013 International Journal of Welfare for the Aged Vol.28 No.-

In this study, we analyzed various factors for attitudes about old people and aging. In purpose of this study was twofold: first, we examined the relationships between demographic variables such as age, gender, education, marital status and attitude toward aging; and second we examined the relationships between personality traits such as neuroticism, extraversion, and conscientiousness and attitude toward aging. Subjects were a convenience sample of 312 college students (mean age = 20.8, SD = 3.1) at a university in Upstate New York. Questionnaires included demographic factors, the Reaction to Ageing Questionnaire (RAQ), and three personality traits from NEO-Five Factor Inventory (NEO-FFI). The most influential factors for improving positive attitudes are experiences with old people. Pearson correlations showed that two personality traits such as neuroticism and conscientiousness were correlated with overall attitude toward aging.

Evolutionary insights into gymnosperm genomes resulting from the Norway spruce genome project

Nathaniel Street 한국육종학회 2013 한국육종학회 심포지엄 Vol.2013 No.07

Conifers have been the dominant tree species of many forests for more than 200 million years and are currently ecologically and economically extremely important species. Despite their importance there has, to date, been no gymnosperm genome sequence available. We produced a draft assembly of the 20 Gbp Norway spruce (Picea abies) genome. Ab initio gene prediction identified 28,354 well-supported genes representing a gene number similar to the >100 times smaller genome of Arabidopsis thaliana. Analysis of synonymous substitutions per synonymous site (Ks) identified no evidence of a recent whole-genome duplication suggesting that genome expansion resulted from other mechanisms. Repeat analysis showed that the large genome resulted from the slow and steady accumulation of a diverse set of LTR TEs that were not subsequently removed by unequal recombination, as evidenced by a high abundance of complete LTRs with few solo LTRs being identified. We performed low coverage sequencing of Pinus sylvestris, Abies sibirica, Juniperus communis, Taxus baccata and Gnetum gnemon to enable comparative analyses, revealing that the TE diversity is shared among extant conifers. Profiling of 24nt sRNAs, which are known to silence TEs via methylation, was highly tissue-specific and much lower than in other plants. We further identified numerous long (>10,000 bp) introns that arose due to TE insertions and that seem to be shared across gymnosperm species in addition to the genome containing numerous gene-like fragments, most likely representing pseudogenes. We additionally identified 13,031 spruce-specific and 9,686 conserved long non-coding RNAs, 2,719 miRNA candidates and show that the 21nt sRNA population is highly diverse, as reported previously for other conifer species. The availability of a conifer genome will enable further advances in conifer forestry and breeding as well as enabling evolutionary analysis including this previously missing group of land plants.

다중해상도 탐색을 이용한 반복 일반화 허프 변환

이경미(Kyoung-Mi Lee),W. Nick Street(W. Nick Street) 한국정보과학회 2003 정보과학회논문지 : 소프트웨어 및 응용 Vol.30 No.9·10

이 논문은 주어진 영상에 존재하는 물체를 자동적으로 탐지하기 위한 시간과 공간 효율적인 방법을 소개한다. 일반화 허프 변환(Generalized Hough Transform: GHT)은 다양한 모양의 물체를 찾기 위해 자동 물체 탐지를 하는 강력한 템플릿(template) 매칭 알고리즘이다. 다양한 모양과 크기의 물체를 찾기 위해 서로 다른 많은 템플릿을 GHT에 적용해야 한다. GHT로 찾아진 모든 경계선은 보다 정교한 경계선을 찾기 위한 초기 외곽선으로 사용된다. 그러나, GHT의 주요 단점은 과도한 시간과 공간을 요구하는 것이다. 이런 단점을 극복하기 위해서, 제안된 알고리즘은 공간 효율적 방법인 반복적 GHT(iterative GHT: IGHT)를 사용한다. 또한, 원래 영상의 크기를 이분의 일 크기와 사분의 일 크기로 줄여서 다중 해상도 탐색을 이용한다. 사분의 일 영상에서 첫 번째 IGHT를 수행하여 획득한 정보를 이용하고, 세포 크기의 범위를 줄여 이분의 일 크기의 영상에서 탐색공간을 제한한다. 이분의 일 크기의 영상에서 두 번째 IGHT를 수행한 후, 세포핵은 세부 탐색에 의해 찾아지고, 정확한 경계선을 결정하기 위한 에지 정보에 의해 분할된다. 실험결과는 이 방법이 정확도의 손실이 없으면서, 수행시간과 메모리 사용을 줄이고 있음을 보여준다. This paper presents an efficient method for automatically detecting objects in a given image. The GHT is a robust template matching algorithm for automatic object detection in order to find objects of various shapes. Many different templates are applied by the GHT in order to find objects of various shapes and size. Every boundary detected by the GHT scan be used as an initial outline for more precise contour-finding techniques. The main weakness of the GHT is the excessive time and memory requirements. In order to overcome this drawback, the proposed algorithm uses a multiresolution search by scaling down the original image to half-sized and quarter-sized images. Using the information from the first iterative GHT on a quarter-sized image, the range of nuclear sizes is determined to limit the parameter space of the half-sized image. After the second iterative GHT on the half-sized image, nuclei are detected by the fine search and segmented with edge information which helps determine the exact boundary. The experimental results show that this method gives reduction in computation time and memory usage without loss of accuracy.
