protein aggregation and precipitation is associated with many debilitating diseases including alzheimer's, parkinson's, and light-chain amyloidosis. β-casein, a member of the casein family, has been demonstrated to exhibit chaperone-like activity to protect protein form aggregation. hofmeister salts (lyotropice series) are a class of ions which have an effect on the solubility and also the stab...

This work is focused in the ID generation problem in mobile environments. We discuss the suitability of traditional mechanisms and techniques to generate IDs in mobile environments. Based on the “Birthday Problem”, we deduced some formulas to evaluate the ID trust that is directly related to the number of entities in the system. The estimation of the system size revels to be the main problem of...

We present a progressive 3D localization algorithm for obtaining fairly precise position estimations in spite of highly imprecise and error-prone distance measurements from low cost hardware. At the same time, we achieve a high localization frequency, reduce energy for wireless data aggregation and require very little memory. We also provide a quality and trust classifier for each estimation. T...

This study extends the previous research framework—the TOE (technological, organizational, and environmental perspectives) model of technological innovation—by using a revised model—the TOIM (technological, organizational, interorganizational, and marketplace perspectives) model. The study tests additional variables, including trust (interorganizational perspective), aggregation, and service qu...

Authenticated dictionaries allow users to send lookup requests to an untrusted server and get authenticated answers. Persistent authenticated dictionaries (PADs) add queries against historical versions. We consider a variety of different trust models for PADs and we present several extensions, including support for aggregation and a rich query language, as well as hiding information about the o...

In this paper we give an overview of the DBin Semantic Web information manager. Then we describe how it enables users to create and experience the Semantic Web by exchanging RDF knowledge in P2P "topic" channels. Once sufficient information has been collected locally, rich and fast browsing of the Semantic Web becomes possible without generating external traffic or computational load. In this w...

The problem of encouraging trustworthy behavior in P2P online communities by managing peers’ reputations has drawn a lot of attention recently. However, most of the proposed solutions exhibit the following two problems: huge implementation overhead and unclear trust related model semantics. In this paper we show that a simple probabilistic technique, maximum likelihood estimation namely, can re...

In this report we address the role of trust in autonomous systems, and our progress in developing a theory of interdependence for the efficient control of hybrid teams and systems composed of robots, machines and humans working interchangeably. Sentient multi-agent systems require an aggregation process like data fusion. But conventional use of fusion for the control of UxV systems hinges on co...

With the development of e-commerce, digital intermediaries have joined the value chain linking suppliers and consumers. These intermediaries add value by undertaking several roles: aggregation, facilitation, matching and providing an environment of trust for transacting parties. In the public sector, the UK Government is driving forward the introduction of electronic service delivery by local a...
