In this paper we introduce an instant online community (IOC) solution as an add-on for existing websites. The IOC enables social interaction between the main content provider and visitors of one or more websites. We present the successful application of the sixgroups.com Livecommunity in the context of a joint conference to support communication between organizers and attendees, and attendees a...

We examine the welfare effects of price and disclosure regulation in a model where firms can shroud add-on costs, such as penalty fees for consumer financial products. Such regulation can increase or decrease welfare even when there are no direct costs. There are, however, strong complementarities between price controls and disclosure mandates: conditional on disclosure be­ ing mandated, price ...

This paper describes a Web proxy architecture called WebPADS, short for “Web Proxy for Actively Deployable Services.” The WebPADS was developed to enhance Web applications running on a wireless network. The WebPADS provides mechanisms to automatically locate and configure a flexible and adaptive wireless Web proxy. In addition, it provides a framework that facilitates the development of add-on ...

For a very general class of probability distributions in disordered Ising spin systems, in the thermodynamical limit, we prove the following property for overlaps among real replicas. Consider the overlaps among s replicas. Add one replica s + 1. Then, the overlap q as+1 between one of the rst s replicas, let us say a, and the added s + 1 is either independent of the former ones, or it is ident...

This introductory presentation describes the Overlap Dirac Operator, why it could be useful in numerical QCD, and how it can be implemented.

Regge theory provides an excellent description of small-x structurefunction data from Q = 0 up to the highest available values. The large-Q data should also be described by perturbative QCD: the two descriptions must agree in the region where they overlap. However, at present there is a serious lack in our understanding of how to apply perturbative QCD at small x. The usual lowestorder or next-...

An overlap method for regularizing Majorana–Weyl fermions interacting with gauge fields is presented. A mod(2) index is introduced in relation to the anomalous violation of a discrete global chiral symmetry. Most of the paper is restricted to 2 dimensions but generalizations to 2+8k dimensions should be straightforward.

What is it about context that determines whether a target will be assimilated to the context or contrasted away from it? We suggest that it is the dimensional overlap in the range of values that contextual and target stimuli might take. Four experiments demonstrate that overlap or lack thereof between context and target ranges determines context effects. Assimilation occurs when the context and...

| Additive synthesis is a powerful tool for the analysis/modiication/synthesis of complex audio or speech signals. However, the cost of wavetable sinusoidal synthesis can become prohibitive for large numbers of sinusoids (more than a few hundred). In that case, techniques based on the inverse Fourier transform ooer an attractive alternative, being 200% to 300% more eecient than wavetable synthe...
