Pharmacogenetic Smoking Cessation Intervention in a Health Care Setting: A Pilot Feasibility Study
We conducted a multiphased, mixed-methods feasibility study with current smokers to develop and evaluate a patient-centered, theoretically grounded personalized medicine treatment protocol.

Design-Based Implementation Research: An Emerging Model for Transforming the Relationship of Research and Practice
We describe the need for DBIR as a research approach that challenges educational researchers and practitioners to transcend traditional research/practice barriers to facilitate the design of educational interventions that are effective, sustainable, and scalable.

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.

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.

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.

Alpha7 Neuronal Nicotinic Receptors as a Drug Target in Schizophrenia
Preclinical and clinical data suggest that neuronal α7nAChRs play an important role in cognitive functions. Moreover, some, but not all, early clinical trials conducted with α7nAChR agonists show cognitive benefits in schizophrenics.

Sparse Conditional Mixture Model: Late Fusion with Missing Scores for Multimedia Event Detection
We present the Sparse Conditional Mixture Model (SCMM) which models only the observed detection scores for each example, thereby avoiding making any assumptions about the distributions of the scores that are made by backoff models.
