Hurdles to widespread adoption of these techniques include the quality, uncertainty, and variability of the measurements. The objective of this paper is to evaluate the multifactor effects of collecting ride quality measurements from smartphones and how crowdsourcing using measurements from a population of different vehicles can be used to overcome or mitigate the effects of less resolute and more variable measurements. This investigation was carried out using two experiments. First, a full factorial design of experiment (DOE) was developed to evaluate the multifactor effects on ride quality measurements using the average rectified slope (ARS). Second, a custom DOE with the objective of analyzing the ARS from a population of vehicles from different classifications was carried out. The results from the first experiment suggested that individual factors contribute to statistical differences in ARS measurements. However, the second experiment showed that when looking into a population of vehicles with randomly sampled factors, the ARS measurements converge, and the statistical analysis showed no significance. This approach can be successfully implemented using a crowdsourcing approach where the focus is to analyze a population of vehicles instead of individual measurements.}, number={4}, journal={JOURNAL OF TRANSPORTATION ENGINEERING PART B-PAVEMENTS}, author={Medina, Jose R. and Salim, Ramadan and Underwood, B.

Fruit}, volume={63}, ISSN={["1520-5118"]}, url={http://www.scopus.com/inward/record.url?eid=2-s2.0-84949504941&partnerID=MN8TOARS}, DOI={10.1021/acs.jafc.5b04781}, abstractNote={Extracts of Styrax ramirezii Greenm., a fruit traditionally valued for health and wellness in Mexico, were analyzed phytochemically and evaluated for antioxidant and anti-inflammatory activity. Six norneolignans were identified by HPLC-TOF-MS, and the two major compounds were isolated for further evaluation. The effects of the isolated norneolignans, egonol and homoegonol, on lipopolysaccharide (LPS)-induced nitric oxide (NO) production, reactive oxygen species (ROS) production, and biomarkers of inflammation were evaluated. Of the tested compounds, egonol potently inhibited the production of NO and also significantly reduced the release of ROS. Consistent with these observations, the mRNA expression levels of inducible nitric oxide synthase (iNOS) (0.668 ± 0.108), cyclooxygenase-2 (COX-2) (0.553 ± 0.007), interleukin-1β (IL-1β) (0.093 ± 0.005), and interleukin-6 (IL-6) (0.298 ± 0.076) were reduced by egonol. The activity for both egonol and homoegonol increased in a concentration-dependent manner. These results suggest the potential of S. ramirezii Greenm. fruit to contribute to a healthy diet, rich in antioxidant and anti-inflammatory compounds.}, number={48}, journal={JOURNAL OF AGRICULTURAL AND FOOD CHEMISTRY}, author={Timmers, Michael A. and Guerrero-Medina, Jorge L. and Esposito, Debora and Grace, Mary H. and Paredes-Lopez, Octavio and Garcia-Saucedo, Pedro A. and Ann Lila, Mary}, year={2015}, month={Dec}, pages={10459–10465} }

Polyphenolics were concentrated (10-42 mg/g range) in dry muscadine-protein matrices. Kale-fortified protein matrices also captured polyphenolics (8 mg/g), carotenoids (69 μg/g) and glucosinolates (7 μmol/g). Neither total phenolics nor glucosinolates were significantly diminished even after long term (6 months) storage at 4, 20, or 37 °C, whereas carotenoids degraded over time, particularly at higher temperatures. Dry biofortified phytoactive-protein ingredients allowed delivery of immunoprotective compounds from fruits and vegetables in a stable, lightweight matrix.}, number={4}, journal={PLANT FOODS FOR HUMAN NUTRITION}, author={Yousef, Gad G. and Grace, Mary H. and Medina, Jorge L.
