Synthesis and Thermoluminescence Characteristics of Gamma and Proton Irradiated Nanocrystalline MgB4o7: Dy, Na
This paper investigates the use of nanocrystalline MgB4O7: Dy, Na thermoluminescent (TL) dosimeter synthesized by the combustion method for the assessment of proton beam and gamma radiation doses, primarily on the shape of the TL glow curves.

Nicotine-Mediated Improvement in L-Dopa-Induced Dyskinesias in MPTP-Lesioned Monkeys is Dependent on Dopamine Nerve Terminal Function
The present work was done to understand the factors that regulate the nicotine-mediated reduction in LIDs in MPTP-lesioned nonhuman primates.

Evaluation of Reagentless pH Modification for in Situ Ocean Analysis: Determination of Dissolved Inorganic Carbon Using Mass Spectrometry
The reagentless electrolytic technique for pH modification presented here was developed primarily to ease and to extend the longevity of dissolved inorganic carbon (DIC) determinations in seawater, but can also be used for other analytical methods.

R-MASTIF: Robotic Mobile Autonomous System for Threat Interrogation and Object Fetch
The SRI-UPenn team fielded a modified Segway RMP 200 robot with multiple cameras and lidars. We implemented a unique computer vision based approach for textureless colored object training and detection to robustly locate previ-ously unseen objects out to 15 meters on moderately flat terrain.

Immunoregulatory Profile of Monocytes from Cutaneous Leishmaniasis Patients and Association with Lesion Size
We evaluated peripheral blood CD14+ monocytes for the expression of immunoregulatory cytokines, co-stimulatory molecules and TLR9 from cutaneous leishmaniasis patients infected with L. braziliensis and noninfected individuals.

Scanning Gate Microscopy of Localized States in Wide Graphene Constrictions
We use a scanning gate microscope to probe a short, wide graphene constriction and observe a set of ring-shaped resonances in maps of the graphene conductance as a function of the local potential perturbation, a signature of quantum dot-mediated transport.

Discovery of a Splicing Regulator Required for Cell Cycle Progression
Here we describe a new G1 mutant from an ancient family of apicomplexan protozoans. Toxoplasma gondii temperature-sensitive mutant 12-109C6 conditionally arrests in the G1 phase due to a single point mutation in a novel protein containing a single RNA-recognition-motif (TgRRM1).
