Bottom-Up/Top-Down Image Parsing with Attribute Grammar
We present a simple attribute graph grammar as a generative representation for made-made scenes and studies an effective top-down/bottom-up inference algorithm for parsing images in the process of maximizing a…

Classification and Selective Collection of Individual Aerosol Particles Using Laser-Induced Fluorescence
We describe the development and performance evaluation of a system for optical interrogation, subsequent selection, and collection of individual aerosol particles entrained in an inlet air stream.

WikiWalk: Random walks on Wikipedia for semantic relatedness
This paper evaluates methods for building the graph, including link selection strategies, and two methods for representing input texts as distributions over the graph nodes: one based on a dictionary…

Combining Semantic and Syntactic Information Sources for 5-W Question Answering
This paper focuses on combining answers generated by a semantic parser that produces semantic role labels (SRLs) and those generated by syntactic parser that produces function tags for answering 5-W…

Enhanced Alpha-Synuclein Expression in Human Neurodegenerative Diseases: Pathogenetic and Therapeutic Implications
Here we discuss the possibility that other mechanisms of alpha-synuclein elevation contribute to the pathogenesis of idiopathic, sporadic Parkinson's disease and other human synucleinopathies.

Morphology of Graphene on Sic (000 1-) Surfaces
Graphene is formed on SiC(000-1) surfaces (the so-called C-face of the crystal) by annealing in vacuum, with the resulting films characterized by atomic force microscopy, Auger electron spectroscopy, scanning Auger…

NASA LaRC Airborne High Spectral Resolution Lidar Aerosol Measurements During MILAGRO: Observations and Validation
This paper presents high spatial and vertical resolution HSRL measurements of aerosol extinction and optical depth from MILAGRO and comparisons of those measurements with similar measurements from other sensors and…

PANTHER Pathway: an Ontology-Based Pathway Database Coupled with Data Analysis Tools
This chapter first discusses how biological knowledge is represented, particularly the importance of ontologies or standards in systems biology research.

Prediction and Discovery of Users’ Desktop Behavior
We show that efficient many-class learning can perform well for action prediction in the Unix domain, significantly improving over previously published results.

Adaptive Security in Broadcast Encryption Systems (With Short Ciphertexts)
We present new techniques for achieving adaptive security in broadcast encryption systems. Previous work on fully collusion resistant broadcast encryption systems with very short ciphertexts was limited to considering only static security.

Status of Genetic Studies of Nicotine Dependence
This volume examines conceptual, theoretical, and methodological considerations in the development of nicotine-dependence phenotypes and endophenotypes.
