  • Wu, You; Picard, Mathieu; Baelden, Camille; Slocum, Alexander H.; Chang, Le (American Nuclear Society, 2014-11)
    Uranium present in low concentration in ocean water has the potential to greatly augment the current fuel reserve for nuclear power generation, but the challenge of extracting it economically remains. Two new designs of ...
  • Brar, B.; Kim, D. H.; del Alamo, Jesus A.; Antoniadis, Dimitri A. (Institute of Electrical and Electronics Engineers, 2010-03)
    We have experimentally extracted the virtual-source electron injection velocity, vx0, of various III-V HFETs at room temperature. This is the carrier velocity that matters for logic applications of these transistors. Sub-100 ...
  • Conlon, David; Fox, Jacob; Zhao, Yufei (Elsevier, 2014-02)
    Szemeredi's regularity lemma is a fundamental tool in extremal combinatorics. However, the original version is only helpful in studying dense graphs. In the 1990s, Kohayakawa and Rodl proved an analogue of Szemeredi's ...
  • Sindelka, Radek; Chen, Justin; Rothman, Alyssa; Dickinson, Amanda J.; Jacox, Laura A.; Sive, Hazel L. (Elsevier, 2014-07)
    The extreme anterior domain (EAD) is a conserved embryonic region that includes the presumptive mouth. We show that the Kinin-Kallikrein pathway is active in the EAD and necessary for craniofacial development in Xenopus ...
  • Spokoyny, Alexander M.; Lewis, Calvin D.; Teverovskiy, Georgiy; Buchwald, Stephen Leffler (American Chemical Society (ACS), 2012-11)
    We have prepared the first examples of B9-connected trivalent aryl and alkyl phosphinoborane species via Pd-catalyzed phosphination of 9-iodo-meta-carborane. Our studies highlight the unique electronic features of the ...
  • Simcoe, Robert A.; Sullivan, Peter W.; Kao, Melodie M.; Burgasser, Adam J.; Cooksey, Kathy; Matejek, Michael Scott (Nature Publishing Group, 2012-12)
    In typical astrophysical environments, the abundance of heavy elements ranges from 0.001 to 2 times the solar value. Lower abundances have been seen in selected stars in the Milky Way’s halo(1, 2, 3) and in two quasar ...
  • Yunes, Nicolas; Buonanno, Alessandra; Hughes, Scott A.; Pan, Yi; Barausse, Enrico; Miller, M. Coleman; Throwe, William T. (American Physical Society, 2011-02)
    We construct effective-one-body waveform models suitable for data analysis with the Laser Interferometer Space Antenna for extreme mass-ratio inspirals in quasicircular, equatorial orbits about a spinning supermassive black ...
  • Gou, Lijun; McClintock, Jeffrey E.; Reid, Mark J.; Orosz, Jerome A.; Steiner, James F.; Narayan, Ramesh; Xiang, Jingen; Remillard, Ronald Alan; Arnaud, Keith A.; Davis, Shane W. (Institute of Physics/American Astronomical Society, 2011-12)
    The compact primary in the X-ray binary Cygnus X-1 was the first black hole to be established via dynamical observations. We have recently determined accurate values for its mass and distance, and for the orbital inclination ...
  • Vucelja, M.; Chertkov, M.; Turitsyn, Konstantin (American Physical Society, 2015-02)
    We analyze the statistics of work generated by a gradient flow to stretch a nonlinear polymer. We obtain the large deviation function (LDF) of the work in the full range of appropriate parameters by combining analytical ...
  • Cai, Yang; Daskalakis, Konstantinos (Institute of Electrical and Electronics Engineers (IEEE), 2011-10)
    We provide a Polynomial Time Approximation Scheme for the multi-dimensional unit-demand pricing problem, when the buyer's values are independent (but not necessarily identically distributed.) For all ϵ >; 0, we obtain a ...
  • Wang, Jingfeng; Bras, Rafael L. (American Meteorological Society, 2010-02)
    An extremum hypothesis of turbulent transport in the atmospheric surface layer is postulated. The hypothesis has led to a unique solution of Monin–Obukhov similarity equations in terms of simple expressions linking shear ...
  • Skow, Bradford (Oxford University Press (OUP), 2010-02)
    When distinguishing absolute, true, and mathematical time from relative, apparent, and common time, Newton wrote: “absolute, true, and mathematical time, in and of itself and of its own nature, without reference to ...
  • Tambe, Prasanna; Hitt, Lorin M.; Brynjolfsson, Erik (Institute for Operations Research and the Management Sciences (INFORMS), 2012-01)
    We gather detailed data on organizational practices and information technology (IT) use at 253 firms to examine the hypothesis that external focus—the ability of a firm to detect and therefore respond to changes in its ...
  • Trifonova, Radiana; Jhunjhunwala, Siddharth; Hartoularos, George C.; Eyerman, Alexandra T.; Lytton-Jean, Abigail; Angin, Mathieu; Sharma, Siddhartha; Poceviciute, Roberta; Mao, Shirley; Heimann, Megan; Liu, Sophia; Talkar, Tanya; Khan, Omar F.; Addo, Marylyn M.; von Andrian, Ulrich H.; Langer, Robert; Lieberman, Judy; Jensen, Klavs F.; Sharei, Armon Reza; Anderson, Daniel Griffith (Public Library of Science, 2015-04)
    Intracellular delivery of biomolecules, such as proteins and siRNAs, into primary immune cells, especially resting lymphocytes, is a challenge. Here we describe the design and testing of microfluidic intracellular delivery ...
  • Kim, Ki-Hean; So, Peter T. C.; Sun, Tzu-Lin; Liu, Yuan; Sung, Ming-Chin; Yang, Chun-Hui; Hovhannisyan, Vladimir; Chen, Wei-Liang; Chen, Yang-Fang; Chen, Hsiao-Ching; Chiou, Ling-Ling; Huang, Guan-Tarn; Lin, Wei-Chou; Jeng, Yung-Ming; Lee, Hsuan-Shu; Dong, Chen-Yuan (SPIE, 2010-06)
    Conventionally, liver fibrosis is diagnosed using histopathological techniques. The traditional method is time-consuming in that the specimen preparation procedure requires sample fixation, slicing, and labeling. Our goal ...
  • Bryan, Bradley; Wang, Yihong; Connolly, James L.; Zhou, Chao; Aguirre, Aaron Dominic; Tsai, Tsung-Han; Fujimoto, James G. (Society of Photo-optical Instrumentation Engineers, 2009-02)
    We report an imaging study using integrated 3D-OCT and OCM for the assessment of various human thyroid and breast pathologies. The 3D-OCT data sets enable en face projection imaging, which provides large field of view with ...
  • Fujimoto, James G.; Zhou, Chao; Tsai, Tsung-Han; Aguirre, Aaron Dominic; Wang, Yihong; Cohen, David W.; Connolly, James L. (Society of Photo-optical Instrumentation Engineers, 2010-02)
    We evaluate the feasibility of optical coherence tomography (OCT) and optical coherence microscopy (OCM) for imaging of benign and malignant thyroid lesions ex vivo using intrinsic optical contrast. 34 thyroid gland specimens ...
  • Huang, Fu-Chung; Wetzstein, Gordon; Barsky, Brian A.; Raskar, Ramesh (Association for Computing Machinery, 2014-07)
    Millions of people worldwide need glasses or contact lenses to see or read properly. We introduce a computational display technology that predistorts the presented content for an observer, so that the target image is ...
  • Rus, Daniela L.; Vona, Marsette A.; Quigley, Kevin (Institute of Electrical and Electronics Engineers, 2010-03)
    It is never too early to introduce students to robotics. Inspired by courses that use Lego Mindstorms as platform, by the huge success of the FIRST competition, and by the interest and enthusiasm of many local robotics ...
  • Temereanca, Simona; Hamalainen, Matti S.; Kuperberg, Gina R.; Stufflebeam, Steven M.; Halgren, Eric; Brown, Emery N. (Society for Neuroscience, 2012-03)
    Active reading requires coordination between frequent eye movements (saccades) and short fixations in text. Yet, the impact of saccades on word processing remains unknown, as neuroimaging studies typically employ constant ...
