Spatially Correlated Fluctuations and Coherence Dynamics in Photosynthesis
Here we present a generic model in which a strong intermolecular steric restoring force in densely packed pigment-protein complexes results in a spatial correlation in conformational (static) variations of chromophores,…

High throughput membrane-less water purification
This paper describes a highly scalable fluidic technology that presents a transformative approach to the practice of conventional water treatment.

Scalable architecture for context-aware activity-detecting mobile recommendation systems
In this paper we describe the implementation of a mobile recommender system for leisure activities, codenamed Magitti, which was built for commercial deployment under stringent scalability requirements.

An integrated approach to qualitative model-based diagnosis
In this paper we propose a first step towards developing a more integrated multi-faceted approach to qualitative model-based reasoning.

Understanding the efficiency of social tagging systems using information theory
We analyze a social tagging site, namely del.icio.us, with information theory in order to evaluate the efficiency of this social tagging site for encoding navigation paths to information sources.

Using utility and microutility to manage resources in vehicle ad hoc networks
In this paper we describe how sources can model the potential usefulness of their information using utility functions that describe where and at what data rates the information will be…

Using utility and microutility to manage resources in vehicle ad hoc networks
We describe an approach to propagating streams of information in Vehicle Ad-Hoc Networks (VANETs) based on sources of information predicting where the information will be useful---information is pushed "based on…

Low cost, membrane-less water purification
PARC has developed a compact, low-cost purification system that reduces maintenance down-time, increases throughput, decreases power consumption, and shrinks real estate requirements.

Real-Time Global Localization with a Pre-Built Visual Landmark Database
In this paper, we study how to build a vision-based system for global localization with accuracies within 10 cm. for robots and humans operating both indoors and outdoors over wide…

Collision Sensing by Stereo Vision and Radar Sensor Fusion
To take the advantages of both stereo cameras and radar, this paper proposes a fusion approach to accurately estimate the location, size, pose and motion information of a threat vehicle…

HO2: A New Feature for Multi-Agent Event Detection and Recognition
In this paper, we present a new feature to model a class of events that consist of complex interactions among multiple entities captured by tracks and inter-object relationships over space…

Nociceptin Attenuates Methamphetamine Abstinence-Induced Withdrawal-Like Behavior in Planarians
In the present study, we tested the hypothesis that abrupt discontinuation of methamphetamine would also cause withdrawal-like behavior in planarians and that the withdrawal-like behavior would be prevented by nociceptin,…
