  • Huang, Tao; Wang, Junjie; Cai, Yu-Dong; Yu, Hanry; Chou, Kuo-Chen (Public Library of Science, 2012-04)
    Hepatitis C virus (HCV) is a main risk factor for liver cirrhosis and hepatocellular carcinoma, particularly to those patients with chronic liver disease or injury. The similar etiology leads to a high correlation of the ...
  • Kinsy, Michel A.; Pellauer, Michael; Devadas, Srinivas (Association for Computing Machinery (ACM), 2013-02)
    This paper presents Heracles, an open-source, functional, parameterized, synthesizable multicore system toolkit. Such a multi/many-core design platform is a powerful and versatile research and teaching tool for architectural ...
  • Tanji, Haruka; Simon, Jonathan; Ghosh, Saikat; Bloom, Benjamin; Vuletic, Vladan (Royal Swedish Academy of Sciences, 2009-07)
    We describe the mapping of quantum states between single photons and an atomic ensemble. In particular, we demonstrate a heralded quantum memory based on the mapping of a photon polarization state onto a single collective-spin ...
  • Simon, Jonathan; Ghosh, Saikat; Vuletic, Vladan; Bloom, Benjamin; Tanji, Haruka (American Physical Society, 2009-07)
    We demonstrate a heralded quantum memory where a photon announces the mapping of a light polarization state onto a single collective-spin excitation (magnon) shared between two atomic ensembles. The magnon can be converted ...
  • Rosenberg, Danna; Stelmakh, Veronika; Grein, Matthew E.; Bennink, Ryan S.; Dauler, Eric A.; Kerman, Andrew J.; Molnar, Richard J.; Wong, Franco N. C.; Dixon, P. Benjamin (American Physical Society, 2014-10)
    We report on a systematic experimental study of the heralding efficiency and generation rate of telecom-band infrared photon pairs generated by spontaneous parametric down-conversion and coupled to single-mode optical ...
  • Ofer, Oren; Keren, Amit; Brewer, Jess H.; Han, Tianheng; Lee, Young S. (IOP Publishing, 2011-04)
    We present transverse field muon spin rotation/relaxation measurements on single crystals of the spin-1/2 kagome antiferromagnet Herbertsmithite. We find that the spins are more easily polarized when the field is perpendicular ...
  • Cesarini, David Alexander; Johannesson, Magnus; Lichtenstein, Paul; Wallance, Bjorn (MIT Press, 2009-04)
    Empirical evidence suggests that people on average overestimate their own ability in a variety of circumstances. Little is known, however, about the origins of such overconfidence. To shed some light on this issue, we use ...
  • Zhu, Qi; Song, Yiying; Hu, Siyuan; Li, Xiaobai; Tian, Moqian; Zhen, Zonglei; Dong, Qi; Kanwisher, Nancy; Liu, Jia (Elsevier Ltd., 2010-01)
    What makes one person socially insightful but mathematically challenged, and another musically gifted yet devoid of a sense of direction? Individual differences in general cognitive ability are thought to be mediated by ...
  • Lindquist, Susan; Brown, Jessica C.S. (Cold Spring Harbor Laboratory Press, 2009-10)
    Several well-characterized fungal proteins act as prions, proteins capable of multiple conformations, each with different activities, at least one of which is self-propagating. Through such self-propagating changes in ...
  • Lindquist, Susan; Saibil, Helen R.; Seybert, Anja; Habermann, Anja; Winkler, Juliane; Eltsov, Mikhail; Perkovic, Mario; Castano-Diez, Daniel (National Academy of Sciences (U.S.), 2012-08)
    Yeast prions constitute a “protein-only” mechanism of inheritance that is widely deployed by wild yeast to create diverse phenotypes. One of the best-characterized prions, [PSI+], is governed by a conformational change in ...
  • Heimbach, Patrick; Kalmikov, Alex (Society for Industrial and Applied Mathematics, 2014-10)
    Derivative-based methods are developed for uncertainty quantification (UQ) in large-scale ocean state estimation. The estimation system is based on the adjoint method for solving a least-squares optimization problem, whereby ...
  • Koutsoyiannis, D.; Makropoulos, C.; Langousis, Andreas; Baki, S.; Efstratiadis, A.; Christofides, A.; Karavokiros, G.; Mamassis, N. (European Geosciences Union / Copernicus, 2009-02)
    Since 1990 extensive funds have been spent on research in climate change. Although Earth Sciences, including climatology and hydrology, have benefited significantly, progress has proved incommensurate with the effort and ...
  • Jones, Kevin C.; Ganim, Ziad; Tokmakoff, Andrei (American Chemical Society, 2009-11)
    We develop heterodyned dispersed vibrational echo spectroscopy (HDVE) and demonstrate the new capabilities in biophysical applications. HDVE is a robust ultrafast technique that provides a characterization of the real and ...
  • Ren, Y.; Gao, J. R.; Hovenier, J. N.; Higgins, R.; Zhang, W.; Bell, A.; Klein, B.; Klapwijk, T. M.; Shi, S. C.; Kao, Tsung-Yu; Kumar, S.; Hu, Qing; Reno, J. L. (SPIE, 2010-07)
    High-resolution heterodyne spectrometers operating at above 2 THz are crucial for detecting, e.g., the HD line at 2.7 THz and oxygen OI line at 4.7 THz in astronomy. The potential receiver technology is a combination of a ...
  • Yao, Huajian; van der Hilst, Robert D.; Montagner, Jean-Paul (American Geophysical Union, 2010-12)
    Understanding the geotectonic evolution of the southeastern Tibetan plateau requires knowledge about the structure of the lithosphere. Using data from 77 broadband stations in SW China, we invert Rayleigh wave phase velocity ...
  • Ryan, Stephen; Tucker, Catherine Elizabeth (Springer-Verlag, 2011-08)
    We estimate the demand for a videocalling technology in the presence of both network effects and heterogeneity. Using a unique dataset from a large multinational firm, we pose and estimate a fully dynamic model of technology ...
  • Abaluck, Jason; Gruber, Jonathan (American Economic Association, 2011-05)
    This paper investigates the degree to which choice inconsistencies documented in the context of Medicare Part D plan choice vary across consumers and geographic regions. Our main finding is that there is surprisingly little ...
  • Weis, Victoria G.; Sousa, Josane F.; LaFleur, Bonnie J.; Nam, Ki Taek; Weis, Jared A.; Finke, Paul E.; Ameen, Nadia A.; Fox, James G.; Goldenrign, James R. (BMJ Publishing Group, 2012-07)
    Objectives: Spasmolytic polypeptide-expressing metaplasia (SPEM) develops as a preneoplastic lesion in the stomachs of mice and humans after parietal cell loss. To identify the commonalities and differences between phenotypic ...
  • Hu, Jie; Locasale, Jason W; Bielas, Jason H; O'Sullivan, Jacintha; Sheahan, Kieran; Cantley, Lewis C; Vander Heiden, Matthew G.; Vitkup, Dennis (Nature Publishing Group, 2013-04)
    Reprogramming of cellular metabolism is an emerging hallmark of neoplastic transformation. However, it is not known how the expression of metabolic genes in tumors differs from that in normal tissues, or whether different ...
  • Chen, Hui; Joslin, Scott Stephen Walter; Tran, Ngoc-Khanh (American Economic Association, 2010-01)
    We illustrate the effects of heterogeneous beliefs about disasters on the equity premium and individual agents’ trading activities. When investors disagree about the chances or severity of disasters, those optimistic ...
