Presupernova Structure of Massive Stars

Issues concerning the structure and evolution of core collapse progenitor stars are discussed with an emphasis on interior evolution. We describe a program designed to investigate the transport and mixing processes associated with stellar turbulence, arguably the greatest source of uncertainty in progenitor structure, besides mass loss, at the time of core collapse. An effort to use precision observations of stellar parameters to constrain theoretical modeling is also described.Comment: Proceedings for invited talk at High Energy Density Laboratory Astrophysics conference, Caltech, March 2010.

Comprehensive Rare Variant Analysis via Whole-Genome Sequencing to Determine the Molecular Pathology of Inherited Retinal Disease

Inherited retinal disease is a common cause of visual impairment and represents a highly heterogeneous group of conditions. Here, we present findings from a cohort of 722 individuals with inherited retinal disease, who have had whole-genome sequencing (n = 605), whole-exome sequencing (n = 72), or both (n = 45) performed, as part of the NIHR-BioResource Rare Diseases research study. We identified pathogenic variants (single-nucleotide variants, indels, or structural variants) for 404/722 (56%) individuals. Whole-genome sequencing gives unprecedented power to detect three categories of pathogenic variants in particular: structural variants, variants in GC-rich regions, which have significantly improved coverage compared to whole-exome sequencing, and variants in non-coding regulatory regions. In addition to previously reported pathogenic regulatory variants, we have identified a previously unreported pathogenic intronic variant in $\textit{CHM}$ in two males with choroideremia. We have also identified 19 genes not previously known to be associated with inherited retinal disease, which harbor biallelic predicted protein-truncating variants in unsolved cases. Whole-genome sequencing is an increasingly important comprehensive method with which to investigate the genetic causes of inherited retinal disease.This work was supported by The National Institute for Health Research England (NIHR) for the NIHR BioResource – Rare Diseases project (grant number RG65966).

Automating workflows with service oriented media applications

This paper describes the infrastructure we have built for the automation of several typical workflows in a professional media production environment. We fully adopted the service oriented architecture and business process management vision in which stand-alone services provide modular functionality, service invocations are being orchestrated by a process engine and human interaction is possible in the business process through human tasks. The architecture was designed, the infrastructure was built, services were implemented, and several workflows were automated

Automating media processes in a Service Oriented Architecture

This paper describes how an infrastructure can be built for automating workflows in content production using a service oriented architecture (SOA). We fully adopted the SOA and the Business Process Management (BPM) vision in which stand-alone services provide modular functionality, service invocations are being orchestrated by a process engine, and human interaction is possible in the business processes through human tasks. We aimed at increased efficiency and control, shorter setup times, and increased flexibility. Our architecture is illustrated with a use case in which we automated a process that deals with the intake, review, transcoding and publishing of user-generated content
