  • Gait Detection in Children with and without Hemiplegia Using Single-Axis Wearable Gyroscopes 

    Abaid, Nicole; Cappa, Paolo; Palermo, Eduardo; Petrarca, Maurizio; Porfiri, Maurizio (PLOS, 2013-09-04)
    In this work, we develop a novel gait phase detection algorithm based on a hidden Markov model, which uses data from foot-mounted single-axis gyroscopes as input. We explore whether the proposed gait detection algorithm ...

  • Convenient, Rapid and Accurate Measurement of SVOC Emission Characteristics in Experimental Chambers 

    Liu, Cong; Liu, Zhe; Little, John C.; Zhang, Yinping (PLOS, 2013-08-28)
    Chamber tests are usually used to determine the source characteristics of semi-volatile organic compounds (SVOCs) which are critical to quantify indoor exposure to SVOCs. In contrast to volatile organic compounds (VOCs), ...

  • Energy Dense, Protein Restricted Diet Increases Adiposity and Perturbs Metabolism in Young, Genetically Lean Pigs 

    Fisher, Kimberly D.; Scheffler, Tracy L.; Kasten, Steven C.; Reinholt, Brad M.; van Eyk, Gregory R.; Escobar, Jeffery; Scheffler, Jason M.; Gerrard, David E. (PLOS, 2013-08-26)
    Animal models of obesity and metabolic dysregulation during growth (or childhood) are lacking. Our objective was to increase adiposity and induce metabolic syndrome in young, genetically lean pigs. Pre-pubertal female pigs, ...

  • Risk Map of Cholera Infection for Vaccine Deployment: The Eastern Kolkata Case 

    You, Young Ae; Ali, Mohammad; Kanungo, Suman; Sah, Binod; Manna, Byomkesh; Puri, Mahesh; Nair, G. Balakrish; Bhattacharya, Sujit Kumar; Convertino, Matteo; Deen, Jacqueline L.; Lopez, Anna Lena; Wierzba, Thomas F.; Clemens, John; Sur, Dipika (PLOS, 2013-08-02)
    Background Despite advancement of our knowledge, cholera remains a public health concern. During March-April 2010, a large cholera outbreak afflicted the eastern part of Kolkata, India. The quantification of importance ...

  • Network Effects of Risk Behavior Change Following Prophylactic Interventions 

    Rajaraman, Rajmohan; Sun, Zhifeng; Sundaram, Ravi; Vullikanti, Anil Kumar S. (PLOS, 2013-08-01)
    We formulated a network-based model to understand how risk behavior change in conjunction with failure of prophylactic interventions can lead to unintended outcomes where “less (intervention) is more (effective).” Our model ...
