Fe-Radiation-Induced Alterations in Circulating Leukocyte Populations in the Apoe Mouse Atherosclerosis Model Are Temporary
We irradiated ApoE mice with 56Fe focused to the aorta and carotids to determine how irradiation of the thymus with 56Fe affects circulating lymphocyte number, and ultimately to determine the effect of iron ion irradiation on development of atherosclerosis.

A Semantic Web Reasoner for Rules, Equations and Constraints
We describe a reasoner for OWL ontologies and SWRL policies used on cognitive radios to control dynamic spectrum access.

Sioc Ceramic with High Excess Free Carbon
The correlation between microstructure evolution and increasing processing temperature of a polymer-derived SiOC ceramic with a high volume fraction of free carbon was studied by transmission electron microscopy (TEM).

Synthesis and Biological Evaluation of Alpha- and Beta-6-Amido Derivatives of 17-Cyclopropylmethyl-3, 14 Beta-Dihydroxy-4, 5 Alpha-Epoxymorphinan: Potential Alcohol-Cessation Agents
Substituted aryl and aliphatic amide analogues of 6-naltrexamine were synthesized and used to characterize the binding to and functional activity of human μ-, δ-, and κ-opioid receptors.

Using Spectral Characteristics to Interpret Auroral Imaging in the 731.9 Nm O+ Line
Simultaneous observations were made of dynamic aurora during substorm activity on 26 January 2006 with three high spatial and temporal resolution instruments: the ASK (Auroral Structure and Kinetics) instrument, SIF (Spectrographic Imaging Facility) and ESR (EISCAT Svalbard Radar), all located on Svalbard (78° N, 16.2° E).

Observations of Plasma Line Splitting in the Ionospheric Incoherent Scatter Spectrum
Wide-bandwidth ionospheric incoherent scatter (IS) spectra obtained using the Arecibo IS radar show the occurrence of a split in the plasma line (i.e., two plasma lines) when the plasma frequency is close to the second harmonic of the electron gyro-frequency.

The Mineralogy of Shock-Induced Melt Vein in Martian Meteorite Zagami: Shock Pressure and Ejection Mechanism
This is the first report of Post-stishovite was found in zagami meteorite in the maskelynite outside of shock-induced melt vein. The mineralogy assemblages of melt vein, including stishovite, pyroxene and other high-pressure phases reported by others, indicated the melt-vein crystallization pressure and shock pressure were smaller than 25 GPa.

Threshold Collision-Induced Dissociation of Hydrogen-Bonded Dimers of Carboxylic Acids
Energy-resolved competitive collision-induced dissociation is used to investigate the proton-bound heterodimer anions of a series of carboxylic acids (formic, acetic, and benzoic acid) and nitrous acid with their conjugate bases.

Gender Differences In Science
We present a review of research that looks at alternative explanations for these gender differences in science. Specifically, we consider the significance of girls’ science attitudes and the pervasive influence—both direct and indirect—of science stereotypes.

Leaving Flatland: Realtime 3D Stereo Semantic Reconstruction
We report our first experiences with Leaving Flatland, an exploratory project which studies the key challenges in closing the loop on autonomous perception and action in challenging terrain.
