An analysis is presented for both ground- and satellite-based retrievals of total column ozone and nitrogen dioxide levels from the Washington, D.C., and Baltimore, Maryland, metropolitan area during the NASA-sponsored July 2011 campaign of Deriving Information on Surface COnditions from Column and VERtically Resolved Observations Relevant to Air Quality (DISCOVER-AQ). Satellite retrievals of t...

In a joint project with the Netherlands PTT, the Delft University of Technology is developing an interactive protocol design and analysis system named ‘Pandora’. The system provides users with a controlled environment for protocol synthesis and formal analysis, and offers both software and hardware tools for protocol assessment. Pandora can assist the user in the documentation of protocol desig...

We demonstrate that the chaotic orbits of Prometheus and Pandora are due to interactions associated with the 121:118 mean motion resonance. Differential precession splits this resonance into a quartet of components equally spaced in frequency. Libration widths of the individual components exceed the splitting resulting in resonance overlap which causes the chaos. A single degree of freedom mode...

Pattern recognition is the identification of structures and regularities in data. In high energy physics, it is a vital stage in the reconstruction of events recorded by fine-granularity detectors. The development and operation of Liquid Argon Time Projection Chambers (LAr TPCs) for neutrino physics has created a need for new approaches to pattern recognition, in order to fully exploit the supe...

Background: The PANDORA study has recently examined the prevalence of low ankle brachial index (ABI) in subjects with moderate risk of cardiovascular disease. This subanalysis of the PANDORA study examines the prevalence of asymptomatic peripheral arterial disease (PAD), as determined by ABI, in Italian subjects presenting with moderate cardiovascular risk, in the absence of diabetes or overt v...

Accidents have occurred in which failures of digital systems have contributed to property damage, injury, and even loss of life. Most investigative agencies do not know how to investigate these failures comprehensively because the complexity and coupling of a digital system’s functions can obfuscate its design, making it difficult for an investigator to understand the system, and because the un...
