Reduced Parasympathetic Activity During Sleep in the Symptomatic Phase of Severe Premenstrual Syndrome
We investigated HRV during sleep, a state that is relatively free of external disruptions, in 9 women with severe PMS and 12 controls.

Scene-Based Nonuniformity Correction and Enhancement: Pixel Statistics and Subpixel Motion
We propose a framework for scene-based nonuniformity correction (NUC) and nonuniformity correction and enhancement (NUCE) that is required for focal-plane array-like sensors to obtain clean and enhanced-quality images.

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.

Measurement of Debris in the Flow from Pyrotechnic Reactions Using an Instrumented Hopkinson Pressure Bar
When an NASA standard initiator (NSI) combusts within the confinement of a pyrovalve, debris is generated and entrained into flow. This debris can originate from the closure disc, the zirconium…

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.
