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,…

Identification of a Population of Sleep-Active Cerebral Cortex Neurons
We have identified a population of cells in the cortex that is activated during sleep in three mammalian species. These cortical neurons are a subset of GABAergic interneurons that express…

Imaging Radar Observations of Farley Buneman Waves During the Joule Ii Experiment
Vector electric fields and associated E×B drifts measured by a sounding rocket in the auroral zone during the NASA JOULE II experiment in January 2007, are compared with coherent scatter spectra measured…

Ventricular Expansion After Alcohol Exposure By Vapor Chamber in Wistar Rats
Here, we tested the hypothesis that wild-type Wistar rats, exposed to vaporized alcohol ensuring higher BALs than typically achieved with voluntary consumption in rodents, would model MRI findings in the…

Dynamic Facial Expression Analysis and Synthesis with Mpeg-4 Facial Animation Parameters
This paper describes a probabilistic framework for faithful reproduction of dynamic facial expressions on a synthetic face model with MPEG-4 facial animation parameters while achieving very low bitrate in data…

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.
