Development of a biodosimeter for radiation triage using novel blood protein biomarker panels in humans and non-human primates
We are developing a rapid screening method to assess whether an individual received an absorbed dose of ≥2 Gy based on the analysis of a specific panel of blood proteins in…

How accurate is automated gap filling of metabolic models?
Here we compare the results of applying an automated likelihood-based gap filler within the Pathway Tools software with the results of manually gap filling the same metabolic model.

Evaluation of reaction gap-filling accuracy by randomization
We report on computational experiments of reaction gap filling in which we generated degraded versions of the EcoCyc-20.0-GEM model by randomly removing flux-carrying reactions from a growing model.

Design and Verification for Transportation System Security
In this work, we propose an integrated framework that combines hybrid modeling, formal verification, and automated synthesis techniques for analyzing the security and safety of transportation systems and carrying out…

Modification of the Loss Cone for Energetic Particles
The optimal pitch angle which maximizes the penetration distance, along the magnetic field, of relativistic charged particles injected from the midplane of an axisymmetric field is investigated analytically and numerically.

Evaluation of OMI Operational Standard NO2 Column Retrievals Using in Situ and Surface-Based NO2 Observations
We assess the standard operational nitrogen dioxide data product retrieved from the Ozone Monitoring Instrument onboard NASA's Aura satellite using a combination of aircraft and surface in situ measurements.

A Framework for Application of Metabolic Modeling in Yeast to Predict the Effects of Nssnv in Human Orthologs
Here we present the next step in the workflow toward using yeast metabolic modeling to predict human metabolic behavior resulting from nsSNV.

Studies of a Prototype Linear Stationary X-Ray Source for Tomosynthesis Imaging
A prototype linear x-ray source to implement stationary source–stationary detector tomosynthesis (TS) imaging has been studied.

NV-CMOS HD Camera for Day/Night Imaging
SRI International (SRI) has developed a new multi-purpose day/night video camera with low-light imaging performance comparable to an image intensifier, while offering the size, weight, ruggedness, and cost advantages enabled…

Effects of Thermal Treatment on Radiative Properties of HVPE Grown InP Layers
We have studied radiative properties of 21 micron thick InP layers grown by HVPE and found them comparable to those of best luminescent bulk InP virgin wafers. This opens up…

Tracking Elevated Pollution Layers with a Newly Developed Hyperspectral Sun/Sky Spectrometer (4STAR): Results from the TCAP 2012 and 2013 Campaigns
We compare results with coincident measurements. We find 0.045 g/cm2 (4.2%) negative bias and 0.28 g/cm2 (26.3%) root-mean-square difference (RMSD) in water vapor layer comparison with an in situ hygrometer and an overall RMSD…
