    Islet transplantation is a feasible therapeutic alternative for metabolically labile patients with type 1 diabetes. The primary therapeutic target is stable glycemic control and prevention of complications associated with ...
  • Yip, Alexander; Wang, Xi; Zeldovich, Nickolai; Kaashoek, M. Frans (Association for Computing Machinery, 2009-10)
    Resin is a new language runtime that helps prevent security vulnerabilities, by allowing programmers to specify application-level data flow assertions. Resin provides policy objects, which programmers use to specify assertion ...
  • Li, William; Sellers, Clara (Institute of Electrical and Electronics Engineers, 2010-04)
    Assistive technology (AT) describes any device or other solution that is used by people with disabilities to assist in performing tasks or activities. While potentially useful, the availability of appropriate AT for people ...
  • Vosoughi, Soroush (Association for Computing Machinery, 2014)
    In this paper, we present a multimodal speech recognition system for real world scene description tasks. Given a visual scene, the system dynamically biases its language model based on the content of the visual scene and ...
  • Ananthakrishnan, Ashwin N.; Cai, Tianxi; Savova, Guergana; Cheng, Su-Chun; Chen, Pei; Perez, Raul Guzman; Gainer, Vivian S.; Murphy, Shawn N.; Szolovits, Peter; Xia, Zongqi; Shaw, Stanley; Churchill, Susanne; Karlson, Elizabeth W.; Kohane, Isaac; Plenge, Robert M.; Liao, Katherine P. (Lippincott Williams & Wilkins, 2013-06)
    Background: Previous studies identifying patients with inflammatory bowel disease using administrative codes have yielded inconsistent results. Our objective was to develop a robust electronic medical record–based model ...
  • Chen, Kuang; Chen, Harr; Conway, Neil; Dolan, Heather; Hellerstein, Joseph M.; Parikh, Tapan S. (Institute of Electrical and Electronics Engineers, 2010-03)
    Organizations in developing regions want to efficiently collect digital data, but standard data gathering practices from the developed world are often inappropriate. Traditional techniques for form design and data quality ...
  • Banerjee, Abhijit; Duflo, Esther; Glennerster, Rachel; Kothari, Dhruva (BMJ Publishing Group, Ltd., 2010-05)
    Objective To assess the efficacy of modest non-financial incentives on immunisation rates in children aged 1-3 and to compare it with the effect of only improving the reliability of the supply of services. Design ...
  • Pesterev, Aleksey; Strauss, Jacob; Zeldovich, Nickolai; Morris, Robert Tappan (Association for Computing Machinery (ACM), 2012-04)
    Incoming and outgoing processing for a given TCP connection often execute on different cores: an incoming packet is typically processed on the core that receives the interrupt, while outgoing data processing occurs on the ...
  • Qureshi, Asfandyar; Shih, Eugene; Fan, Irene; Carlisle, Jennifer; Brezinski, Donna; Kleinman, Monica; Guttag, John V. (AMIA, 2010-11)
    Telemedicine has had a positive impact on some aspects of patient care. However, existing telemedicine systems that use high-quality video are inflexible, requiring investment in fixed infrastructure. We have overcome a ...
  • Gustavsson, Simon; Zwier, Olger; Bylander, Jonas; Yan, Fei; Yoshihara, Fumiki; Nakamur, Yasunobu; Orlando, Terry Philip; Oliver, William D. (American Physical Society, 2013-01)
    We present a new method for determining pulse imperfections and improving the single-gate fidelity in a superconducting qubit. By applying consecutive positive and negative π pulses, we amplify the qubit evolution due to ...
  • Berwick, Robert C.; Malioutov, Igor Mikhailovich (Institute of Electrical and Electronics Engineers (IEEE), 2011-01)
