The tapestry of biofeedback history has been woven from many independent threads. Some contributors started with much vigor and nurtured others, and then they faded away. Yet they seeded ideas that the next generation rediscovered as their own. Others blossomed and disappeared, whereas still others have continued to actively nurture the field. Interest in biofeedback has waxed and waned in resp...

From classical mechanics to quantum field theory, the physical facts at one point in space are held to be independent of those at other points in space. I propose that we can usefully challenge this orthodoxy in order to explain otherwise puzzling correlations at both cosmological and microscopic scales. “Nature uses only the longest threads to weave her patterns, so that each small piece of he...

Peer-to-peer overlay networks such as CAN, Chord, Pastry, and Tapestry can be used to implement Internet-scale application-level multicast. There are two general approaches to accomplishing this: tree building (used by Bayeux and Scribe); and flooding (used by CAN Multicast). This paper presents of an evaluation of these two approaches using CAN and Pastry as the underlying overlay networks. We...

We addressed the problem of recovering or “rejuvenating” colors in a faded tapestry (the target image) by automatically mapping colors from digital images of the reference painting or cartoon (the source image). We divided the overall computational challenge into several subproblems, and implemented their solutions in Matlab: 1) quantizing the colors in both the tapestry and the referent painti...

Structured peer-to-peer overlay networks such as CAN, Chord, Pastry, and Tapestry can be used to implement Internet-scale application-level multicast. There are two general approaches to accomplishing this: tree building and flooding. This paper evaluates these two approaches using two different types of structured overlay: 1) overlays which use a form of generalized hypercube routing, e.g., Ch...

In aspect-oriented programming (AOP) a cross-cutting concern is implemented in an aspect. An aspect weaver blends code from the aspect into a program’s code at programmer-specified cut points, yielding an aspectenhanced program. In this paper we apply some of the concepts from the AOP paradigm to data. Like code, data also has cross-cutting concerns such as versioning, security, privacy, and re...
