  • Ji, Peng; Lodish, Harvey F. (Ferrata Storti Foundation, 2010-01)
    The four members of the Rac family of GTPases –Rac1, Rac2, Rac3 and RhoG – are members of the Rho superfamily that regulates the organization, dynamics, and function of the actin cytoskeleton. Rac GTPases play significant ...
  • Williams, Earle R.; Rickenbach, Thomas; Guy, Nick; Nieto Ferreira, Rosana (American Meteorological Society, 2009-12)
    A radar-based analysis of the structure, motion, and rainfall variability of westward-propagating squall-line mesoscale convective systems (SLMCSs) in Niamey, Niger, during the African Monsoon Multidisciplinary Activities ...
  • Nelson, John A. (Institute of Electrical and Electronics Engineers, 2010-10)
    The second generation of the Radar Open Systems Architecture has been developed and put into practice. This approach consists of a layered architecture that isolates applications from underlying hardware and software ...
  • Xue, Chuan; Othmer, Hans G.; Budrene-Kac, Elena O. (Public Library of Science, 2011-12)
    The enteric bacterium Proteus mirabilis, which is a pathogen that forms biofilms in vivo, can swarm over hard surfaces and form a variety of spatial patterns in colonies. Colony formation involves two distinct cell types: ...
  • Huang, Hui; Yao, Huajian; van der Hilst, Robert D. (American Geophysical Union (AGU), 2010-11)
    We use Rayleigh and Love wave Green's functions estimated from ambient seismic noise to study crustal structure and radial anisotropy in the tectonically complex and seismically active region west of the Sichuan Basin and ...
  • Kumar, Shiva; Pai, Srinivasa; Rao, Shrinivasa (Hindawi Publishing Corporation, 2012)
    Radial basis function neural networks (RBFNNs), which is a relatively new class of neural networks, have been investigated for their applicability for prediction of performance and emission characteristics of a diesel ...
  • Davidson, James West; Korolev, Kirill Sergeevich; Nelson, David R. (American Physical Society, 2013-01)
    We study the effect of spatial structure, genetic drift, mutation, and selective pressure on the evolutionary dynamics in a simplified model of asexual organisms colonizing a new territory. Under an appropriate coarse-graining, ...
  • Franse, Jeroen; Foster, Adam; Boyarsky, Alexey; Markevitch, Maxim; Iakubovskyi, Dmytro; Loewenstein, Mike; Miller, Eric; Randall, Scott W.; Ruchayskiy, Oleg; Smith, Randall K.; Bulbul, Gul E; Bautz, Mark; McDonald, Michael A.; Miller, Eric D (IOP Publishing, 2016-10)
    The recent discovery of the unidentified emission line at 3.5 keV in galaxies and clusters has attracted great interest from the community. As the origin of the line remains uncertain, we study the surface brightness ...
  • Arras, Phil; Burkart, Joshua; Quataert, Eliot; Weinberg, Nevin N. (Oxford University Press, 2012-05)
    Close-in, massive exoplanets raise significant tides in their stellar hosts. We compute the radial velocity (RV) signal due to this fluid motion in the equilibrium tide approximation. The predicted RVs in the observed ...
  • Nikurashin, Maxim Anatolevich; Ferrari, Raffaele (American Meteorological Society, 2009-10)
    Observations and inverse models suggest that small-scale turbulent mixing is enhanced in the Southern Ocean in regions above rough topography. The enhancement extends O(1) km above the topography, suggesting that mixing ...
  • Beyerlein, Irene J.; Caro, A.; Mara, Nathan A.; Misra, Amit; Uberuaga, B. P.; Demkowicz, Michael J. (Elsevier, 2013-11)
    Designing a material from the atomic level to achieve a tailored response in extreme conditions is a grand challenge in materials research. Nanostructured metals and composites provide a path to this goal because they ...
  • Swager, Timothy Manning; Lobez, Jose M. (Wiley Blackwell, 2009-11)
    Detection of gamma rays is shown using a non-scintillating organic-based sensor composed of poly(olefin sulfone)/carbon nanotube blends. Functionalization of the polymers can be performed after polymerization to tailor ...
  • Engelward, Bevin P; Yanch, Jacquelyn C (Environmental Health Perspectives, 2012-11)
    Summary - Melzer raises many interesting points regarding our study of low dose-rate radiation (Olipitz et al. 2012). Responding to his letter gives us the opportunity to clarify the rationale behind some of our approaches ...
  • Gouker, Pascale M.; Wyatt, Peter W.; Yost, Donna-Ruth W.; Chen, Chenson K.; Chen, Chang-Lee; Knecht, Jeffrey M.; Keast, Craig L. (Institute of Electrical and Electronics Engineers, 2009-11)
    We characterized TID effects in MITLL 3DIC technology. We found that the effects were comparable for nFETs on the bottom tier with that on single tier wafers. Less positive charge build-up is observed for wide nFETs on the ...
  • Zhang, Liang; Demkowicz, Michael J (Elsevier, 2014-06)
    We use molecular dynamics to study radiation-induced mixing between low solid solubility metals, focusing on the effect of liquid phase properties, by sequentially performing multiple 10 keV collision cascade simulations ...
  • Athanasiou, Christiana; Chesler, Paul Michael; Liu, Hong; Nickel, Marcel Dominik Johannes; Rajagopal, Krishna (American Institute of Physics, 2010-09)
    The energy density and angular distribution of power radiated by a quark undergoing circular motion in strongly coupled N  =  4 supersymmetric Yang‐Mills (SYM) theory is computed using gauge∕gravity duality. The results ...
  • Lee, Julia C.; Neilsen, Joseph M. G.; Remillard, Ronald Alan (IOP Publishing, 2012-04)
    We present a unifying scenario to address the physical origin of the diversity of X-ray light curves within the ρ variability class of the microquasar GRS 1915+105. This "heartbeat" state is characterized by a bright flare ...
  • Carr, Christopher E.; Rowedder, Holli; Vafadari, Cyrus; Lui, Clarissa S.; Cascio, Ethan; Zuber, Maria T.; Ruvkun, Gary (Mary Ann Liebert, 2013-01)
    Life on Mars, if it exists, may share a common ancestry with life on Earth derived from meteoritic transfer of microbes between the planets. One means to test this hypothesis is to isolate, detect, and sequence nucleic ...
  • Carr, Christopher E.; Rowedder, Holli; Lui, Clarissa S.; Zlatkovsky, Ilya; Papalias, Chris W.; Bolander, Jarie; Myers, Jason W.; Bustillo, James; Rothberg, Jonathan M.; Ruvkun, Gary; Zuber, Maria (Mary Ann Liebert, 2013-06)
    Life beyond Earth may be based on RNA or DNA if such life is related to life on Earth through shared ancestry due to meteoritic exchange, such as may be the case for Mars, or if delivery of similar building blocks to ...
  • Rieder, Harald E.; Ivy, Diane J; Solomon, Susan (American Meteorological Society (AMS), 2016-06)
    Radiative and dynamical heating rates control stratospheric temperatures. In this study, radiative temperature trends due to ozone depletion and increasing well-mixed greenhouse gases from 1980 to 2000 in the polar ...
