Architecting the cyberinfrastructure for National Science Foundation Ocean Observatories Initiative (OOI)
The NSF Ocean Observatories Initiative (OOI) is a networked ocean
research observatory with arrays of instrumented water column moorings and
buoys, profilers, gliders and autonomous underwater vehicles (AUV) within different
open ocean and coastal regions. OOI infrastructure also includes a cabled
array of instrumented seafloor platforms and water column moorings on the
Juan de Fuca tectonic plate. This networked system of instruments, moored and
mobile platforms, and arrays will provide ocean scientists, educators and the
public the means to collect sustained, time-series data sets that will enable examination
of complex, interlinked physical, chemical, biological, and geological
processes operating throughout the coastal regions and open ocean. The seven
arrays built and deployed during construction support the core set of OOI multidisciplinary
scientific instruments that are integrated into a networked software
system that will process, distribute, and store all acquired data. The OOI
has been built with an expectation of operation for 25 years.Peer Reviewe
Guest Editors Introduction: Extreme Data
The guest editors discuss work that can accelerate insights from extreme data, from innovative algorithmic formulations to implementation frameworks and software stacks
Guest Editors Introduction: Cloud Computing
The guest editors discuss this special issue on cloud computing, exploring how cloud platforms and abstractions can be effectively used to support real-world science and engineering applications
Survey and Analysis of Production Distributed Computing Infrastructures
This report has two objectives. First, we describe a set of the production
distributed infrastructures currently available, so that the reader has a basic
understanding of them. This includes explaining why each infrastructure was
created and made available and how it has succeeded and failed. The set is not
complete, but we believe it is representative.
Second, we describe the infrastructures in terms of their use, which is a
combination of how they were designed to be used and how users have found ways
to use them. Applications are often designed and created with specific
infrastructures in mind, with both an appreciation of the existing capabilities
provided by those infrastructures and an anticipation of their future
capabilities. Here, the infrastructures we discuss were often designed and
created with specific applications in mind, or at least specific types of
applications. The reader should understand how the interplay between the
infrastructure providers and the users leads to such usages, which we call
usage modalities. These usage modalities are really abstractions that exist
between the infrastructures and the applications; they influence the
infrastructures by representing the applications, and they influence the ap-
plications by representing the infrastructures
Acute ST elevation myocardial infarction after intravenous immunoglobulin infusion in a young patient: a rare but probable adverse effect of immunoglobulin
Intravenous immunoglobulin (IVIG) is used in the treatment of a variety of disorders, including autoimmune conditions. IVIG has been considered a safe medication, with minor and transient adverse effects. With the wider use of IVIG, the reported rate of adverse effects has been increased, some of them are potentially fatal cardiovascular reactions due to induction of hypercoagulable state. We report a 40-year-old female treated with IVIG for Guillain-Barre syndrome, who developed chest pain 1 hr following IVIG infusion. The symptoms were associated with ST elevation in anterior leads on electrocardiogram. This anterior wall myocardial infarction (MI) is compatible with IVIG-induced hypercoagulability and considered as a probable adverse effect of this medication. To the best of our knowledge, this is probably the first case report where a young patient developed acute MI without any cardiac risk factors after IVIG infusion
