First Estimates of Global Free-Tropospheric NO2 Abundances Derived Using a Cloud-Slicing Technique Applied to Satellite Observations from the Aura Ozone Monitoring Instrument (OMI)
We derive free-tropospheric NO2 volume mixing ratios (VMRs) by applying a cloud-slicing technique to data from the Ozone Monitoring Instrument (OMI) on the Aura satellite.

Development of a Novel Bioadhesive Microbicide Gel Formulation for Prophylactic Protection against Hiv and Hsv-2
Over-the-counter access to an inexpensive, effective topical microbicide could reduce the transmission of HIV and would increase women’s control over their health and eliminate the need to obtain their partners’…

Diagnostics of an Artificial Relativistic Electron Beam Interacting with the Atmosphere
We use a Monte Carlo model to simulate the interaction of a beam of relativistic electrons with the upper atmosphere as they are injected downward from a notional high-altitude injection…

Smten with Satisfiability-Based Research
We present Smten, a high-level language for orchestrating and constructing satisfiability-based search queries. We show that applications developed using Smten require significantly fewer lines of code and less developer effort…

A Framework for High-Assurance Quasi-Synchronous Systems
In this paper, we examine the foundations of a quasi-synchronous model of computation Our version of the quasi-synchronous model is inspired by the Robot Operating System (ROS).

Mechanized Support for Assurance Case Argumentation
We propose simple ways in which an assurance case, formalized in a mechanized verification system to support the first purpose, can be adapted to serve the second.

A Computational Photography Shootout: Wavefront Coding Vs. Lattice Focal Imaging
We systematically compared the optical performance of two computational photography (CP) approaches used to extend the depth of field of an imaging system: wavefront coding and lattice focal lens imaging.

On the Generation/Decay of the Storm-Enhanced Density Plumes: Role of the Convection Flow and Field-Aligned Ion Flow
We present observations of SED plumes during six storms between 2010 and 2013 and comprehensively analyze the associated ionospheric parameters within the plumes.
