Automated fault detection in violation enforcement cameras within electronic toll collection systems
To address this problem, we present algorithmic tools that can be used to automatically review images to detect any potential camera faults, thus, reduce human workload and increase maintenance efficiency.

Closing the Rural Education Math Gap – A Program with Promising Results
Developing strong foundational math skills has been a challenge for schools in rural areas, which serve almost 10 million U.S. students—more than 20 percent of the student population. By engaging rigorous evaluation techniques, SRI International researchers will develop an understanding of the critical factors in closing the rural education math gap. Our research will help a…

Racial/Ethnic Differences in Hospital Use and Cost among a Statewide Population of Children with Down Syndrome
This study generated population-based estimates of hospital use and cost to 3 years of age by race/ethnicity among children with DS in Massachusetts using birth certificates linked to birth defects registry and hospital discharge data from 1999 to 2004.

Multiple CNS Nicotinic Receptors Mediate L-Dopa-Induced Dyskinesias: Studies with Parkinsonian Nicotinic Receptor Knockout Mice
Accumulating evidence supports the idea that drugs acting at nicotinic acetylcholine receptors (nAChRs) may be beneficial for Parkinson’s disease.

A Selective Insular Perfusion Deficit Contributes to Compromised Salience Network Connectivity in Recovering Alcoholic Men
We propose that attenuated insular CBF is a mechanism underlying compromised connectivity among salience network nodes. This local perfusion deficit in alcoholics has the potential to impair ability to switch from cognitive states of interoceptive cravings to cognitive control for curbing internal urges.

Measuring Mitochondrial Metabolism in Rat Brain in Vivo Using Mr Spectroscopy of Hyperpolarized [2-C-13]Pyruvate
In this study, single-time-point chemical shift imaging data were acquired from rat brain in vivo. [5-13C]Glutamate, [1-13C]acetylcarnitine and [1-13C]citrate were detected in addition to resonances from [2-13C]Pyr and [2-13C]Lac.

Quantitative LC-MS/MS Analysis of Seven Ginsenosides and Three Aconitum Alkaloids in Shen-Fu Decoction
We successfully developed a rapid resolution liquid chromatography coupled with tandem mass spectrometry (RRLC-MS/MS) method for the simultaneous analysis of seven ginsenosides and three aconitum alkaloids in Shen-Fu decoction, the decoction of Radix ginseng and Fuzi ( Radix Aconiti lateralis praeparata ).
