Scientific Workflows at Fermilab Using On-demand Services in the Cloud
No full text
The FermiCloud project exists to provide on-demand computing and data
movement services to the various experiments at Fermilab. We face a
dynamically changing demand for compute resources and data movement, which
we meet by enabling our users to run on our own site, remote grid sites, and
cloud sites. We also instantiate on-demand data movement and web caching
services to support this remote analysis. In this presentation we will
briefly summarize some of the recent research results of our recent students
and outline the challenges of the research problems in our current project.
These include coordinated launches of compute nodes plus data movement
servers, interoperability with new commercial clouds, and exploration of new
distributed storage models.

Steven Bryant’s Solace: a conductor’s analysis and performance guide
No full textThe purpose of this study was to examine Solace, a musical composition for wind ensemble, by Steven Bryant composed for the University of North Carolina at Greensboro Wind Ensemble and premiered at the 2013 College Band Directors National Association National Conference. Through a conductor's analysis and performance guide, the author provided insight and background knowledge to all future performers and interpreters of the work through unique first hand accounts from commission to premiere performance. The research method included three processes: 1. A detailed analysis of the musical score, 2. The observation of rehearsals and recording sessions during preparation for the premiere performance of Solace by the University of North Carolina at Greensboro Wind Ensemble, Kevin M. Geraldi, conductor, 3. Extensive interviews of Steven Bryant, composer and Kevin M. Geraldi, conductor. Through examination of prior research on electro-acoustic works for wind ensemble, the author examined Solace within those constructs. Because of the blurring of lines between electronics and acoustic sound, the author further identified Solace as a unique musical composition within the electro-acoustic genre

Unified mathematical treatment of complex cascaded bipartite networks: The case of collections of journal papers
No full textIn this study, a mathematical treatment is proposed for analysis of entities and relations among entities in
complex networks consisting of cascaded bipartite networks. This treatment is applied to the case of
collections of journal papers. In this case, entities are distinguishable objects and concepts, such as papers,
references, paper authors, reference authors, paper journals, reference journals, institutions, terms, and term
definitions. Relations are associations between entity-types such as papers and the references they cite, or
paper authors and the papers they write. An entity-relationship model is introduced that explicitly shows
direct links between entity-types and possible useful indirect relations. From this a matrix formulation and
generalized matrix arithmetic are introduced that allow easy expression of relations between entities and
calculation of weights of indirect links and co-occurrence links. Occurrence matrices, equivalence
matrices, membership matrices and co-occurrence matrices are described. A dynamic model of growth
describes recursive relations in occurrence and co-occurrence matrices as papers are added to the paper
collection. Graph theoretic matrices are introduced to allow information flow studies of networks of papers
linked by their citations. Similarity calculations and similarity fusion are explained. Derivation of feature
vectors for pattern recognition techniques is presented. The relation of the proposed mathematical
treatment to seriation, clustering, multidimensional scaling, and visualization techniques is discussed. It is
shown that most existing bibliometric analysis techniques for dealing with collections of journal papers are
easily expressed in terms of the proposed mathematical treatment: co-citation analysis, bibliographic
coupling analysis, author co-citation analysis, journal co-citation analysis, Braam-Moed-vanRaan (BMV)
co-citation/co-word analysis, latent semantic analysis, hubs and authorities, and multidimensional scaling.
This report discusses an extensive software toolkit that was developed for this research for analyzing and
visualizing entities and links in a collection of journal papers. Additionally, an extensive case study is
presented, analyzing and visualizing 60 years of anthrax research through a collection of journal papers.
When dealing with complex networks that consist of cascaded bipartite networks, the treatment presented
here provides a general mathematical framework for all aspects of analysis of static network structure and
network dynamic growth. As such, it provides a basic paradigm for thinking about and modeling such
networks: computing direct and indirect links, expressing and analyzing statistical distributions of network
characteristics, describing network growth, deriving feature vectors, clustering, and visualizing network
structure and growth
Provenance-based trust for grid computing: Position Paper
No full textCurrent evolutions of Internet technology such as Web Services, ebXML, peer-to-peer and Grid computing all point to the development of large-scale open networks of diverse computing systems interacting with one another to perform tasks. Grid systems (and Web Services) are exemplary in this respect and are perhaps some of the first large-scale open computing systems to see widespread use - making them an important testing ground for problems in trust management which are likely to arise. From this perspective, today's grid architectures suffer from limitations, such as lack of a mechanism to trace results and lack of infrastructure to build up trust networks. These are important concerns in open grids, in which "community resources" are owned and managed by multiple stakeholders, and are dynamically organised in virtual organisations. Provenance enables users to trace how a particular result has been arrived at by identifying the individual services and the aggregation of services that produced such a particular output. Against this background, we present a research agenda to design, conceive and implement an industrial-strength open provenance architecture for grid systems. We motivate its use with three complex grid applications, namely aerospace engineering, organ transplant management and bioinformatics. Industrial-strength provenance support includes a scalable and secure architecture, an open proposal for standardising the protocols and data structures, a set of tools for configuring and using the provenance architecture, an open source reference implementation, and a deployment and validation in industrial context. The provision of such facilities will enrich grid capabilities by including new functionalities required for solving complex problems such as provenance data to provide complete audit trails of process execution and third-party analysis and auditing. As a result, we anticipate that a larger uptake of grid technology is likely to occur, since unprecedented possibilities will be offered to users and will give them a competitive edge

Survival of Salmonella typhimurium, Listeria monocytogenes and indicator bacteria on cooked uncured turkey loaf stored under vacuum at 3°C
No full textSterile slices of cooked uncured turkey loaf were inoculated with 106 CFU of either Salmonella typhimurium, Listeria monocytogenes, Escherichia coli, Enterococcus faecalis, Citrobacter freundii, Klebsiella pneumoniae, or Enterobacter cloacae. Inoculated samples were vacuum‐packaged and stored at 3 ± 1°C. Microorganisms were enumerated at 0, 3, 6, 9, 12, and 15 days on nonselective media. K. pneumoniae exhibited the least cold‐tolerance with a log10 1.70 decrease in numbers. The coliforms E. cloacae, E. coli, and C. freundii had a survival pattern similar to that of S. typhimurium, with population decreases of log10 0.65, 0.82, 1.13, and 0.79, respectively. E. faecalis and L. monocytogenes were significantly more cold‐resistant, with a decrease of log10 0.20 and no significant change in numbers, respectively. Survival of E. faecalis was not significantly (p < 0.01) different than that of L. monocytogenes, suggesting the use of enterococci as indicators of L. monocytogenes contamination of processed meats.Peer reviewedfinal article publishe

Is the debt crisis history? Recent private capital inflows to developing countries
No full textThe outlook for economic development for an important group of middle-income countries has again been buoyed by substantial private capital inflows in the 1990s. As in the 1970s, this development has been met with cautious optimism. It is generally accepted that these countries need resource transfers from the rest of the world to support capital formation and growth. It is also generally accepted that these private capital flows make the allocation of resources more efficient. But there is concern that a rapid reversal of market sentiment could impose considerable adjustment costs on these same economies. The authors try to quantify what many consider to be the main reasons debtor countries have access to capital markets again: (a) Domestic policy reform in the debtor countries. (b) Debt and debt service reduction, usually associated with Brady Plan restructuring. (c) Changes in the external market, such as changes in interest rates in industrial countries. They argue that a useful barometer for access to new loans is the market value of existing sovereign debt. It follows that a quantitative analysis of the factors that caused the market value of sovereign debts to rise rapidly after 1989 would also improve understanding of the forces behind the renewed access to international capital. Empirical historical evidence suggests that fiscal reform, privatization, and debt reduction are useful in explaining relative improvements in the standing of debtor countries in international credit markets. Debtor countries with strong reform programs, in other words, are better prepared to withstand deterioration in the external environment. But the reduction in dollar interest rates since 1989 appears to be the chief factor in the debtor countries'renewed access to international loans. The authors estimate the effect of increases in dollar interest rates and conclude that the typical debtor country remains vulnerable to increases in interest rates that are well within the range of recent experience.Economic Theory&Research,Environmental Economics&Policies,Banks&Banking Reform,Strategic Debt Management,Financial Intermediation
