The Coating Hypothesis for Ammonia Ice Particles in Jupiter: Laboratory Experiments and Optical Modeling
We report laboratory experiments and modeling calculations investigating the effect of a hydrocarbon coating on ammonia ice spectral signatures.

Energetics of SixOyCz Polymer-Derived Ceramics Prepared Under Varying Conditions
In this work, we support earlier studies that the resistance to crystallization of these nanodomain networks is due to thermodynamic as well as kinetic factors.

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.

Hypoxia Signals Autophagy in Tumor Cells Via AMPK Activity, Independent of HIF-1, BNIP3, and BNIP3L
Here we report that oxygen deprivation can activate the autophagic pathway in human cancer cell lines. We observed that hypoxia induced distinct cellular changes characteristic of autophagy such as an…

Image-Guided Surgical Navigation in Implant-Based Auricular Reconstruction
In cases where surgical reconstruction is not an option, placement of osseo-integrated implants for an auricular prosthesis can be done in 1 or 2 stages in a relatively short period…

Scene-Based Nonuniformity Correction Using Local Constant Statistics
Our method proposes a local-constant statistics that assumes that the temporal signal distribution is not constant at each pixel but is locally true.
