Spectroscopic SWIFT

INTRODUCTION Often the ability to obtain chemical-shift information is needed and advantageous in MRI. In addition to providing chemical information, the acquired spectral dimension can also be used to reduce image blur resulting from frequency shifts of all types. This work describes a new 3D and 4D spectroscopic technique involving an intrinsic frequency dimension. The method is based on an o...

Swift Regular Expression Matching

Queries involving Regular Expressions (RegEx) have a wide range of applications including document stores, bioinformatics and information retrieval. However, efficiently executing RegEx queries over large datasets remains a challenging task. Data scans do not scale well with input size; however, existing techniques that avoid data scans — referred to as “black-box” approaches — offer little or ...

Provenance management in Swift

The Swift parallel scripting language allows for the specification, execution and analysis of large-scale computations in parallel and distributed environments. It incorporates a data model for recording and querying provenance information. In this article we describe these capabilities and evaluate interoperability with other systems through the use of the Open Provenance Model. We describe Sw...
