  • Jung, Sung Mi; Jung, Hyun Young; Dresselhaus, Mildred; Jung, Yung Joon; Kong, Jing (Nature Publishing Group, 2012-11)
    Aerogels have numerous applications due to their high surface area and low densities. However, creating aerogels from a large variety of materials has remained an outstanding challenge. Here, we report a new methodology ...
  • Manna, Cesar M.; Nassar, Mostafa Y.; Tofan, Daniel; Chakarawet, Khetpakorn; Cummins, Christopher C. (Royal Society of Chemistry, 2014)
    We herein report the preparation of several mononuclear-metaphosphate complexes using simple techniques and mild conditions with yields ranging from 56% to 78%. Treatment of cyclo-tetrametaphosphate ([TBA]4[P4O12]·5H2O, ...
  • Cho, Daehwan; Kim, Moonkyoung; Hwang, Jeonghyun; Park, Jay Hoon; Joo, Yong Lak; Jeong, Youngjin (Biomed Central Ltd., 2015-10)
    We report a facile fabrication of porous silicon nanofibers by a simple three-stage procedure. Polymer/silicon precursor composite nanofibers are first fabricated by electrospinning, a water-based spinning dope, which ...
  • Mehta, Soham Uday; Yao, JiaXian; Ramamoorthi, Ravi; Durand, Fredo (Association for Computing Machinery (ACM), 2014-07)
    Monte Carlo (MC) ray-tracing for photo-realistic rendering often requires hours to render a single image due to the large sampling rates needed for convergence. Previous methods have attempted to filter sparsely sampled ...
  • Bauer, Christian W.; Tackmann, Frank; Walsh, Jonathan R.; Zuberi, Saba (American Physical Society, 2012-04)
    Multijet cross sections at the LHC and Tevatron are sensitive to several distinct kinematic energy scales. When measuring the dijet invariant mass mjj between two signal jets produced in association with other jets or weak ...
  • Tackmann, Frank; Waalewijn, Wouter Jonathan; Stewart, Iain (American Physical Society, 2010-05)
    We study proton-(anti)proton collisions at the LHC or Tevatron in the presence of experimental restrictions on the hadronic final state and for generic parton momentum fractions. At the scale Q of the hard interaction, ...
  • Slotine, Jean-Jacques E.; Belabbas, M. -A. (Institute of Electrical and Electronics Engineers (IEEE), 2010-07)
    In this paper, we introduce new results in the analysis of convergence of nonlinear systems. The point of view we take is the one of contraction theory and we focus in particular on convergence to smooth manifolds. A main ...
  • Pridgen, Eric; Molnar, Linda K.; Farokhzad, Omid C.; Alexis, Frank (American Chemical Society (ACS), 2008-08)
    Nanoparticle (NP) drug delivery systems (5−250 nm) have the potential to improve current disease therapies because of their ability to overcome multiple biological barriers and releasing a therapeutic load in the optimal ...
  • Lee, Wonyoung; Yildiz, Bilge (Electrochemical Society, 2013-10)
    As the oxygen reduction reaction (ORR) becomes more critical for development of solid oxide fuel cells (SOFCs) that operate at 500-700 °C, the correlation between the surface chemistry and electrochemical performance is ...
  • Molaei, Mehdi; Barry, Michael; Stocker, Roman; Sheng, Jian (American Physical Society, 2014-08)
    Understanding how bacteria move close to surfaces is crucial for a broad range of microbial processes including biofilm formation, bacterial dispersion, and pathogenic infections. We used digital holographic microscopy to ...
  • Gilbertson, Eric W.; Hover, Franz S.; Colina, Ed (American Society of Mechanical Engineers, 2010-06)
    Gas-lifted oil wells are susceptible to failure through malfunction of gas lift valves. This is a growing concern as offshore wells are drilled thousands of meters below the ocean floor in extreme temperature and pressure ...
  • Paparcone, Raffaella; Buehler, Markus J. (Elsevier, 2011-02)
    Amyloid fibrils and plaques are detected in the brain tissue of patients affected by Alzheimer’s disease, but have also been found as part of normal physiological processes such as bacterial adhesion. Due to their highly ...
  • Thompson, Todd Wesley; Waskom, Michael L.; Garel, Keri-Lee Alyson; Cardenas-Iniguez, Carlos; Reynolds, Gretchen O.; Winter, Rebecca; Chang, Patricia; Pollard, Kiersten; Lala, Nupur; Alvarez, George A.; Gabrieli, John D. E. (Public Library of Science, 2013-05)
    Fluid intelligence is important for successful functioning in the modern world, but much evidence suggests that fluid intelligence is largely immutable after childhood. Recently, however, researchers have reported gains ...
  • Evans, David S.; Schmalensee, Richard (Walter de Gruyter, 2010-12)
    Platform businesses add value by facilitating interactions between customers who are attracted in part by network externalities. Two-sided platform businesses with low costs of reversing participation status have become ...
  • Altamirano, D.; Belloni, Tomaso M.; Linares, Manuel Alegret; van der Klis, M.; Wijnands, R.; Curran, P. A.; Kalamkar, M.; Stiele, H.; Motta, S.; Munoz-Darias, T.; Casella, P.; Krimm, H. A. (Institute of Physics/American Astronomical Society, 2011-12)
    We report on the first 180 days of Rossi X-Ray Timing Explorer observations of the outburst of the black hole candidate IGR J17091-3624. This source exhibits a broad variety of complex light curve patterns including periods ...
  • Alesina, Alberto; Angeletos, George-Marios; Cozzi, Guido (American Economic Association, 2013-02)
    This paper responds to the comment of Di Tella and Dubra (2013). We first clarify that the model of Alesina and Angeletos (2005) admits two distinct types of multiplicity: one that is at the core of their contribution, and ...
  • Bertsimas, Dimitris J.; Farias, Vivek F.; Trichakis, Nikolaos (2013-02)
    We propose a scalable, data-driven method for designing national policies for the allocation of deceased donor kidneys to patients on a waiting list in a fair and efficient way. We focus on policies that have the same form ...
  • Jagabathula, Srikanth; Shah, Devavrat (Institute of Electrical and Electronics Engineers (IEEE), 2011-03)
    We consider the problem of designing a fair scheduling algorithm for discrete-time constrained queuing networks. Each queue has dedicated exogenous packet arrivals. There are constraints on which queues can be served ...
  • Pi, So-Young; Jackiw, Roman (American Physical Society, 2015-03)
    We examine the local conformal invariance (Weyl invariance) in tensor-scalar theories used in recently proposed conformal cosmological models. We show that the Noether currents associated with Weyl invariance in these ...
  • Burko, Lior M.; Hughes, Scott A. (American Physical Society, 2010-11)
    The goal of much research in relativity is to understand gravitational waves generated by a strong-field dynamical spacetime. Quantities of particular interest for many calculations are the Weyl scalar psi4, which is simply ...
