Hygroscopic Salts and the Potential for Life on Mars
We modeled the climate conditions in a region on Mars with chloride-bearing evaporites, and modeled the evolution of the water activity of the deliquescence solutions of three possible chloride salts as a function of temperature.

Initial Ionospheric Observations Made By the New Resolute Incoherent Scatter Radar and Comparison to Solar Wind IMF
A summary of 8 days of observations is presented and 10 IMF Bz southward turning events during this period are analyzed in terms of the time delay of plasma density enhancements and ionospheric convection intensification with respect to the timing of Bz southward turning.

Biological Impact of Low Dose-Rate Simulated Solar Particle Event Radiation in Vivo
C57Bl6-lacZ animals were exposed to a range of low dose-rate simulated solar particle event (sSPE) radiation at the NASA-sponsored Research Laboratory (NSRL) at Brookhaven National Laboratory (BNL).

Preclinical Pharmacokinetic, Toxicological and Biomarker Evaluation of SR16157, a Novel Dual-Acting Steroid Sulfatase Inhibitor and Selective Estrogen Receptor Modulator
SR16157 is a novel dual-acting inhibitor of estrogen action that irreversibly inhibits the estrogen biosynthetic enzyme steroid sulfatase and releases the selective estrogen receptor modulator SR16137, which blocks the estrogen receptor.

The Importance of Fuel Dissociation and Propargyl + Allyl Association for the Formation of Benzene in a Fuel-Rich 1-Hexene Flame
Fuel decomposition and benzene formation processes in a premixed, laminar, low-pressure, fuel-rich flame of 1-hexene are investigated.

Middle School Student Mathematics Learning: An Analysis of a Student Population in Texas
We examined the population of students who participated in the seventh-grade year 1 randomized controlled experiment in Texas designed to test the effectiveness of SimCalc in improving student mathematics learning in middle school.

Scaffolding Group Explanation and Feedback with Handheld Technology: Impact on Students’ Mathematics Learning
We compared group and individual learning feedback, using two technologies: (1) Technology-mediated, Peer-Assisted Learning and (2) a popular desktop product, which provides feedback to individual students as they solve fractions problems individually.

Efficient Variable Elimination for Semi-Structured Simple Temporal Networks with Continuous Domains
We show that for an Simple Temporal Network, messages can be represented compactly as sub-STNs. We then present an efficient message-passing scheme for computing the minimal constraints of an STN.

Scaffolding Group Explanation and Feedback with Handheld Technology: Impact on Students’ Mathematics Learning
We compared group and individual feedback, using two technologies: Technology-mediated, Peer-Assisted Learning (TechPALS), and a popular desktop product, which provides feedback to individual students as they solve fractions problems individually.

High-Enthalpy Test Environments, Flow Modeling and in Situ Diagnostics for Characterizing Ultra-High Temperature Ceramics
We describe the test environments generated by two types of these ground test facilities – subsonic inductively coupled plasma tunnels and supersonic arc-jet tunnels – and discuss the important roles of computational fluid dynamics modeling and in situ optical diagnostics for interpreting test results from a materials science perspective.
