Incorporating lexicon knowledge into SVM learning to improve sentiment classification
We present an alternative method that incorporates sentiment lexicons as prior knowledge with machine learning approaches such as SVM to improve the accuracy of sentiment analysis.

Uncertainty Quantification of a Graphite Nitridation Experiment Using a Bayesian Approach
A stochastic system based Bayesian approach is applied to estimate different model parameters and hence quantify the uncertainty of a graphite nitridation experiment.

Infrared Linear Tapered Slot Antenna
For the first time, a tapered slot antenna coupled to a metal-oxide-metal diode is designed, fabricated, and characterized at an infrared wavelength of 10.6 μm.

Geo-Localization of Street Views with Aerial Image Databases
We study the feasibility of solving the challenging problem of geolocalizing ground level images in urban areas with respect to a database of images captured from the air such as satellite and oblique aerial images.

Isotopic Reinforcement of Essential Polyunsaturated Fatty Acids Diminishes Nigrostriatal Degeneration in a Mouse Model of Parkinson’s Disease
We tested the hypothesis that isotopic reinforcement, by deuteration of the bisallylic sites most susceptible to oxidation in PUFA may provide at least partial protection against nigrostriatal injury.

Examining Teachers’ Instructional Moves Aimed at Developing Students’ Ideas and Questions in Learner-Centered Science Classrooms
We examined teachers’ instructional moves to elicit and develop students’ ideas and questions as they orchestrated discourse with their fifth grade students during a learner-centered environmental biology unit.

Toxicogenomics and Metabolomics of Pentamethylchromanol (PMCol)-Induced Hepatotoxicity
The objectives of this study were to determine the mechanisms of the observed toxicity of Pentamethyl-6-chromanol and identify sensitive early markers of target organ injury.

Differential Effects of Nocicetin/Orphanin FQ (NOP) Receptor Agonists in Acute Versus Chronic Pain: Studies with Bifunctional NOP/μ Receptor Agonists in the Sciatic Nerve Ligation Chronic Pain Model in Mice
We identified a novel nociceptin/orphanin FQ (NOP)/μ-opioid receptor agonist, SR 16435, with high binding affinity and partial agonist activity at both receptors.

Sleep, Rhythms, and the Endocrine Brain: Influence of Sex and Gonadal Hormones
This a summary of recent work illustrating how sex differences and gonadal hormones influence sleep and circadian rhythms that was presented at a Mini-Symposium at the 2011 annual meeting of the Society for Neuroscience.

Synthesizing Switching Logic Using Constraint Solving
We present an approach for solving the switching logic synthesis problem in the case when the dynamics in each mode are given using differential equations and the synthesized system is a hybrid system, and the desired property is a safety property.
