  • Busza, Wit (Elsevier, 2009-11)
    In June 2005 the PHOBOS Collaboration completed data taking at RHIC. In five years of operation PHOBOS recorded information for Au+Au at √sNN = 19.6, 62.4, 130, and 200 GeV, Cu+Cu at 22.4, 62.4 and 200 GeV, d+Au at 201 ...
  • Willsky, Alan S.; Pravia, Marco A.; Babko-Malaya, Olga; Schneider, Michael K.; White, James V.; Chong, Chee-Yee (Institute of Electrical and Electronics Engineers, 2009-08)
    Recent experiences in urban operations highlight the need for automated methods to help execute the data collection and association functions in the intelligence process. Technology development in this area has been ...
  • Gurtan, Allan; Ravi, Arvind; Bosson, Andrew David; JnBaptiste, Courtney Kenneil; Bhutkar, Arjun; Whittaker, Charles A.; Young, Richard A.; Sharp, Phillip A.; Rahl, Peter B. (Cold Spring Harbor Laboratory Press, 2013-04)
    MicroRNAs (miRNAs) are critical to proliferation, differentiation, and development. Here, we characterize gene expression in murine Dicer-null adult mesenchymal stem cell lines, a fibroblast cell type. Loss of Dicer leads ...
  • Ackerman, Joshua; Griskevicius, Vladas; Li, Norman P. (American Psychological Association., 2011-06)
    Are men or women more likely to confess love first in romantic relationships? And how do men and women feel when their partners say “I love you”? An evolutionary–economics perspective contends that women and men incur ...
  • Sheng, Morgan Hwa-Tze; Fisher, Daniel; Xing, Bin; Dill, John; Li, Hui; Hoang, Hai Hiep; Zhao, Zhenze; Yang, Xiao-Li; Bachoo, Robert; Cannon, Stephen; Longo, Frank M.; Silver, Jerry; Li, Shuxin (Society for Neuroscience, 2011-10)
    Chondroitin sulfate proteoglycans (CSPGs) are a family of extracellular matrix molecules with various functions in regulating tissue morphogenesis, cell division, and axon guidance. A number of CSPGs are highly upregulated ...
  • Milbradt, Konstantin (Oxford University Press, 2011-11)
    Fair value accounting forces institutions to revalue inventory whenever a transaction occurs. An institution that faces a balance sheet constraint may have incentives to suspend trading in Level 3 assets (traded on opaque ...
  • Cantuti-Castelvetri, Ippolita; Keller-McGandy, Christine E.; Kett, Lauren R.; Landy, Alex; Hollingsworth, Zane R.; Saka, Esen; Crittenden, Jill R.; Nillni, Eduardo A.; Young, Anne B.; Standaert, David G.; Graybiel, Ann M.; F. Hernandez, Ledia (Public Library of Science, 2010-11)
    Background Dyskinesias associated with involuntary movements and painful muscle contractions are a common and severe complication of standard levodopa (L-DOPA, L-3,4-dihydroxyphenylalanine) therapy for Parkinson's ...
  • Williams, M. (Institute of Physics Publishing for SISSA Medialab, 2013-04)
    This paper presents the design of the LHCb trigger and its performance on data taken at the LHC in 2011. A principal goal of LHCb is to perform flavour physics measurements, and the trigger is designed to distinguish charm ...
  • Gill, Mark E.; Hu, Yueh-Chiang; Lin, Yanfeng; Page, David C. (National Academy of Sciences, 2011-05)
    Mammalian oocytes and spermatozoa derive from fetal cells shared by the sexes. These primordial germ cells (PGCs) migrate to the developing somatic gonad, giving rise to oocytes or spermatozoa. These opposing sexual fates ...
  • Hamma, Alioscia; Markopoulou, Fotini; Premont-Schwarz, Isabeau; Severini, Simone (American Physical Society, 2009-01)
    We apply the Lieb-Robinson bounds technique to find the maximum speed of interaction in a spin model with topological order whose low-energy effective theory describes light [see X.-G. Wen, Phys. Rev. B 68, 115413 (2003)]. ...
  • De Sole, Alberto; Kac, Victor (Springer Berlin / Heidelberg, 2009-08)
    We find an interpretation of the complex of variational calculus in terms of the Lie conformal algebra cohomology theory. This leads to a better understanding of both theories. In par- ticular, we give an explicit ...
  • Etingof, Pavel I.; Freund, Rebecca L.; Ma, Xiaoguang (American Mathematical Society, 2009-02)
    Let G=GL(N), K=GL(p) x GL(q), where p+q=N, and let n be a positive integer. We construct a functor from the category of Harish-Chandra modules for the pair (G,K) to the category of representations of the degenerate affine ...
  • Lothon, Marie; Campistron, Bernard; Chong, Michel; Couvreux, Fleur; Guichard, Françoise; Rio, Catherine; Williams, Earle R. (American Meteorology Society, 2011-05)
    On 10 July 2006, during the Special Observation Period (SOP) of the African Monsoon Multidisciplinary Analysis (AMMA) campaign, a small convective system initiated over Niamey and propagated westward in the vicinity of ...
  • Helmreich, Stefan; Roosth, Hannah Sophia (Regents of the University of California, 2010-09)
    We deliver a "keyword" account of the term life form as it has been used in natural philosophy and biology over the last two hundred years, beginning with its appearance in German as Lebensform. We argue that life form ...
  • Raymond, Scott Bruce; Boas, David A.; Kumar, Anand T. N.; Bacskai, Brian J. (SPIE, 2010-08)
    Near-infrared (NIR) fluorescence tomography of multiple fluorophores has previously been limited by the bandwidth of the NIR spectral regime and the broad emission spectra of most NIR fluorophores. We describe in vivo ...
  • Demirtas, Sefa; del Alamo, Jesus A.; Gajewski, Donald A.; Hanson, Allen (CS ManTech, 2009-05)
    We have studied the reliability of intrinsic SiN MIM capacitors designed for 48 V and 125 [superscript 0]C operation and manufactured in a GaN process flow. It is shown that very small area capacitors (10um x 10um) with a ...
  • Szulczewski, Michael Lawrence; MacMinn, Christopher W.; Herzog, Howard J.; Juanes, Ruben (National Academy of Sciences (U.S.), 2012-04)
    In carbon capture and storage (CCS), CO[subscript 2] is captured at power plants and then injected underground into reservoirs like deep saline aquifers for long-term storage. While CCS may be critical for the continued ...
  • Le, Jia-Liang; Bazant, Zdenek P.; Bazant, Martin Z. (American Institute of Physics, 2009-11)
    The two-parameter Weibull distribution has been widely adopted to model the lifetime statistics of dielectric breakdown under constant voltage, but recent lifetime testing for high-k gate dielectrics has revealed a systematic ...
  • Maznev, Alexei; Hofmann, Felix; Jandl, Adam Christopher; Esfarjani, Keivan; Bulsara, Mayank; Fitzgerald, Eugene A.; Chen, Gang; Nelson, Keith Adam (American Institute of Physics (AIP), 2013-01)
    We measure the lifetime of the zone-center 340 GHz longitudinal phonon mode in a GaAs-AlAs superlattice excited and probed with femtosecond laser pulses. By comparing measurements conducted at room temperature and liquid ...
