Trust mechanisms can be computed by modeling a set of agents in a trust graph, a directed weighted graph in which agents are represented as vertices and relative trust as edges. Liu, Parkes, and Seuken [LPS16] present trust mechanisms that are robust against sybil attacks, including the proposed personalized hitting time (PHT) mechanism. In this paper, we propose a scalable algorithm for produc...

In any large software organization, the street cred of source code is of principle concern. Often-times we find that a given code base can talk a mean game, but when time comes to “throw down,” that code base is nowhere to be seen. While intuitively we as software developers come to gain a sense of which code bases are trust-worthy (or, “will ball ‘till they fall”), some systematic method for m...

In open multi-agent systems such as grid-based virtual organizations [1], agents typically need to rely on others for the delivery of information or resources or for the execution of tasks. Since trustworthiness can not be taken for granted, however, an agent needs to build up a measure of her trust in other agents in her environment, and to update it on the basis of her experiences with those ...

Label-free detection of the interaction between hexahistidine-tagged human κ-opioid receptor membrane protein and anti-His antibody is demonstrated in liquid by an optical microelectromechanical system utilizing electromagnetically actuated microresonators. Shift in resonance frequency due to accretion of mass on the sensitive surface of microresonators is monitored via an integrated optical re...

We build a simple model of trust as an equilibrium phenomenon, departing from standard “selfish” preferences in a minimal way. Agents who are on the receiving end of an offer to transact can choose whether to cheat and take away the entire surplus, taking into account a “cost of cheating.” The latter has an idiosyncratic component (an agent’s type), and a socially determined one. The smaller th...

This paper presents a model for more interactive interface agents. This more interactive style of agents aims to increase the trust and understanding between user and agent, by allowing the agent, under certain conditions, to solicit further input from the user about his preferences and desires. With the user and agent engaging in specific clarification dialogues, the user’s input is employed t...

We evaluate the ability of hexahistidine (His6) tags on peptide and protein substrates to recruit deoxyribozymes for modifying those substrates. For two different deoxyribozymes, one that creates tyrosine-RNA nucleopeptides and another that phosphorylates tyrosine side chains, we find substantial improvements in yield, kobs, and Km for peptide substrates due to recruiting by His6/Cu(2+). Howeve...

The field of Multi-agent systems (MAS) has been an active area for many years due to the importance that agents have to many disciplines of research in computer science. MAS are open and dynamic systems where a number of autonomous software components, called agents, communicate and cooperate in order to achieve their goals. In such systems, trust plays an important role. There must be a way fo...
