by David K. Campbell No tribute to the legacy of Stan Ulam would be complete without a discussion of “nonlinear science,” a growing collection of interdisciplinary studies that in the past two decades has excited and challenged researchers from nearly every discipline of the natural sciences, engineering, and mathematics. Through his own research Stan played a major role in founding what we now...

who made all of this possible, for their endless encouragement and patience. iii ACKNOWLEDGEMENTS I owe special thanks to many people, whose support and help were indispensable in completing this thesis. First, I would like to thank my advisors, Dr. and Dr. Jim Rehg, for their thorough guidance of my research and many aspects of my life as a foreign student in this country. The thoughtful discu...

OBJECTIVE To determine the diagnostic value of fetal ST-segment analysis (STAN) in predicting neonatal acidosis. METHODS The STAN S21 was used to monitor singleton fetuses in labor with abnormal FHR. Physicians later reviewed tracings to identify any ST events dictating intervention. Outcome measures were umbilical artery pH< or =7.15 and pH< or =7.05 at birth. The sensitivity, specificity, P...

There is a large body of research devoted to hunting lions in the Sahara Desert [2]. In none of these, however, is any concern given to feeding the lion once it is captured. In this note, we propose feeding Stan Wagon to the lion. Place an orange in the middle of the Sahara Desert. Cut it up into a finite number of pieces and rearrange the pieces to form the Sun. The gravity of the Sun will the...

OBJECTIVE To compare endovascular and standard open repair of abdominal aortic aneurysms in terms of initial in-hospital costs and the costs of secondary interventions and surveillance. DESIGN A retrospective study. SETTING A university-affiliated tertiary care medical centre. PATIENTS Seven patients who underwent elective endovascular (EV) repair of an abdominal aortic aneurysm in 1998 a...

BACKGROUND Exercise is beneficial for breast cancer patients during chemotherapy but adherence to different types and doses of exercise is a challenge. The purpose of this study was to examine predictors of adherence to different types and doses of exercise during breast cancer chemotherapy in a multicenter randomized controlled trial. METHODS Breast cancer patients in Edmonton, Vancouver, an...

Variational inference is a scalable technique for approximate Bayesian inference. Deriving variational inference algorithms requires tedious model-specific calculations; this makes it di cult for non-experts to use. We propose an automatic variational inference algorithm, automatic di erentiation variational inference ( ); we implement it in Stan (code available), a probabilistic programming sy...

This paper is part of a series that focuses on DDI usage and how the metadata specification should be applied in a variety of settings by a variety of organizations and individuals. Support for this working paper series was provided by the authors‘ home institutions; by GESIS Leibniz Institute for the Social Sciences; by Schloss Dagstuhl Leibniz Center for Informatics; and by the DDI Alliance. ...

Die Einführung von Campus-Management-Systemen (CMS) führt zu ei-ner Veränderung der bisherigen dezentralen aufbau-und ablauforganisatorischen Strukturen. Im Rahmen dieser steht die Prozessmodellierung im Vordergrund, wel-che Modellierungswerkzeuge bedingt. Um der Hochschulstruktur und-kultur ge-recht zu werden, erfordert die Modellierung die Verbindung von Standardprozessen mit der in Hochschul...
