This paper introduces the Jade File System, which provides a uniform way to name and access files in an internet environment. Jade is a logical system that integrates a heterogeneous collection of existing file systems, where by heterogeneous we mean that the underlying file systems support different file access protocols. Because of autonomy, Jade is(More)
Slot waveguides allow for high optical confinement in a planar optical waveguide. Here we show a method for maintaining this high degree of confinement in slot waveguides with sharp bends. This high confinement can be achieved by using an asymmetric slot-based structure, where the mode in the bend remains localized in the slot region. We show that the(More)
The paper introduces a transparent service .for synchronized replication across loosely-connected, heterogeneous file systems, and it focuses on the part of the service that supports transactional synchronization. The transaction paradigm is useful for grouping together the file accesses in a program that are logically connected, such that each group of(More)
