Colonic preparation with SPS-Mg is better tolerated, associated with significantly fewer side effects, and results in higher quality bowel cleansing than preparation with PEG-EL.

Traditional file systems provide a weak and inadequate structure for meaningful representations of file interrelationships and other context-providing metadata. Existing designs, which store additional file-oriented metadata either in a database, on disk, or both are limited by the technologies upon which they depend. Moreover, they do not provide for user-defined relationships among files. To address these issues, we created the Linking File System (LiFS), a file system design in which files may have both arbitrary user-or application-specified attributes, and attributed links between files. In order to assure performance when accessing links and attributes, the system is designed to store metadata in non-volatile memory. This paper discusses several use cases that take advantage of this approach and describes the user-space prototype we developed to test the concepts presented.
