  • Giles, M. B.; Vidal-Codina, Ferran; Nguyen, Ngoc Cuong; Peraire, Jaime (Society of Industrial and Applied Mathematics, 2016-01)
    We present an empirical interpolation and model-variance reduction method for the fast and reliable computation of statistical outputs of parametrized stochastic elliptic partial differential equations. Our method consists ...
  • Beesemyer, J. Clark; Rhodes, Donna H.; Ross, Adam Michael (Elsevier, 2012-03)
    Maintaining system performance in the presence of uncertainties in design and operating environments is both challenging and increasingly essential as system lifetimes grow longer. In response to perturbations brought on ...
  • Grinberg, Victoria; Steiner, James F.; McClintock, Jeffrey E.; Pottschmidt, Katja; Rothschild, Richard E.; Garcia, Javier A. (IOP Publishing, 2016-02)
    We have developed a correction tool to improve the quality of Rossi X-ray Timing Explorer (RXTE) High Energy X-ray Timing Experiment (HEXTE) spectra by employing the same method we used earlier to improve the quality of ...
  • McClintock, Jeffrey E.; Steiner, James F.; Grinberg, Victoria; Garcia, Javier A.; Remillard, Ronald Alan (IOP Publishing, 2014-09)
    We fitted all of the several hundred RXTE PCA spectra of the Crab individually to a simple power-law model; the total number of counts in the composite spectrum is >10[superscript 9]. We then used the spectrum of residuals ...
  • Gayeski, Nicholas; Zakula, Tea; Armstrong, Peter R.; Norford, Leslie Keith (American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE), 2010-10)
    Inverter-driven variable-capacity air conditioners, heat pumps, and chillers can provide energy-efficient cooling, particularly at part-load capacity. Varying the capacity of vapor compression systems enables operation at ...
  • Agarwal, Nikhil (American Economic Association, 2015-07)
    This paper develops a framework for estimating preferences in a many-to-one matching market using only observed matches. I use pairwise stability and a vertical preference restriction on one side to identify preferences ...
  • Rambeloarison, Muriel L.; Feizi-Khankandi, Soheil; Angelopoulos, Georgios; Medard, Muriel (Institute of Electrical and Electronics Engineers (IEEE), 2012-11)
    In this paper, we present an empirical rate-distortion study of a communication scheme that uses compressive sensing (CS) as joint source-channel coding. We investigate the rate-distortion behavior of both point-to-point ...
  • Mandelbaum, Tal; Lee, Joon; Scott, Daniel J.; Mark, Roger Greenwood; Malhotra, Atul; Howell, Michael D.; Talmor, Daniel (Springer-Verlag, 2012-12)
    Purpose: The observation periods and thresholds of serum creatinine and urine output defined in the Acute Kidney Injury Network (AKIN) criteria were not empirically derived. By continuously varying creatinine/urine output ...
  • Wang, Pu; Liu, Like; Li, Xiamiao; Li, Guanliang; Gonzalez, Marta C. (Institute of Physics Publishing, 2014-01)
    Navigation problem in lattices with long-range connections has been widely studied to understand the design principles for optimal transport networks; however, the travel cost of long-range connections was not considered ...
  • Hager, Bradford H; Tal, Yuval (American Geophysical Union (AGU), 2015-09)
    Whether fault slip occurs seismically or aseismically depends on the frictional properties of the fault, which might be expected to depend on rock type and depth, as well as other factors. To examine the effect of rock ...
  • Weis, Jonathan Garrett; Ravnsbaek, Jens Bomholdt; Mirica, Katherine; Swager, Timothy M (American Chemical Society (ACS), 2015-11)
    This paper reports the use of halogen bonding interactions for gas-phase detection of pyridine in SWCNT-based chemiresistive sensors with sub-ppm theoretical detection limits. The chemiresistors are prepared by solvent-free ...
  • Tackmann, Frank J.; Waalewijn, Wouter J.; Moult, Ian James; Stewart, Iain (American Physical Society, 2016-05)
    Many state-of-the-art QCD calculations for multileg processes use helicity amplitudes as their fundamental ingredients. We construct a simple and easy-to-use helicity operator basis in soft-collinear effective theory (SCET), ...
  • Christia, Fotini; Beath, Andrew; Enikolopov, Ruben (Cambridge University Press, 2013-07)
    In societies with widespread gender discrimination, development programs with gender quotas are considered a way to improve women's economic, political, and social status. Using a randomized field experiment across 500 ...
  • Shibue, Tsukasa; Weinberg, Robert A (Nature Publishing Group, 2017-04)
    The success of anticancer therapy is usually limited by the development of drug resistance. Such acquired resistance is driven, in part, by intratumoural heterogeneity-that is, the phenotypic diversity of cancer cells ...
  • Shapiro, Irina M.; Cheng, Albert W.; Flytzanis, Nicholas C.; Balsamo, Michele; Condeelis, John S.; Oktay, Maja H.; Burge, Christopher B.; Gertler, Frank (Public Library of Science, 2011-08)
    Epithelial-mesenchymal transition (EMT), a mechanism important for embryonic development, plays a critical role during malignant transformation. While much is known about transcriptional regulation of EMT, alternative ...
  • Kröger, Cornelia; Ye, Xin; Guen, Vincent; Chavarria, Tony E; Weinberg, Robert A; Lees, Jacqueline (National Academy of Sciences (U.S.), 2017-11)
    Tissue regeneration relies on adult stem cells (SCs) that possess the ability to self-renew and produce differentiating progeny. In an analogous manner, the development of certain carcinomas depends on a small subset of ...
  • Zhao, Fang; Qin, Zhengquan; Pereira, Francisco; Li, Corinna Lubin; Zegras, Pericles C; Shahid, Ayesha; Ben-Akiva, Moshe E; Zhao, Jinhua (Transportation Research Board of the National Academies, 2017)
    The growing ubiquity of smartphones offers public transit agencies an opportunity to transform ways to measure, monitor, and manage service performance. The potential of a new tool is demonstrated for engaging customers ...
  • Shapira, Ofer; Abouraddy, Ayman F.; Hu, Qichao; Shemuly, Dana; Joannopoulos, John D.; Fink, Yoel (Optical Society of America, 2010-06)
    The ability to precisely and selectively excite superpositions of specific fiber eigenmodes allows one in principle to control the three dimensional field distribution along the length of a fiber. Here we demonstrate the ...
  • Helmer, Karl G.; Ambite, Jose Luis; Ames, Joseph; Ananthakrishnan, Rachana; Burns, Gully; Chervenak, Ann L.; Foster, Ian; Liming, Lee; Keator, David; Macciardi, Fabio; Madduri, Ravi; Navarro, John-Paul; Potkin, Steven; Rosen, Bruce R.; Ruffins, Seth; Schuler, Robert; Turner, Jessica A.; Toga, Arthur; Williams, Christina; Kesselman, Carl; Biomedical Informatics Research Network (BMJ Publishing Group on behalf of the American Medical Informatics Association, 2011-04)
    Objective As biomedical technology becomes increasingly sophisticated, researchers can probe ever more subtle effects with the added requirement that the investigation of small effects often requires the acquisition of ...
  • Zhen, Bo; Chua, Song Liang; Lee, Jeongwon; Rodriguez, Alejandro; Liang, Xiangdong; Johnson, Steven G; Joannopoulos, John; Soljacic, Marin; Shapira, Ofer (National Academy of Sciences (U.S.), 2013-08)
    The nature of light interaction with matter can be dramatically altered in optical cavities, often inducing nonclassical behavior. In solid-state systems, excitons need to be spatially incorporated within nanostructured ...
