  • Chesler, Paul Michael; Yaffe, Laurence (American Physical Society, 2011-01)
    Using holography, we study the collision of planar shock waves in strongly coupled N=4 supersymmetric Yang-Mills theory. This requires the numerical solution of a dual gravitational initial value problem in asymptotically ...
  • Iqbal, Nabil; Anninos, Dionysios; Hartnoll, Sean A. (American Physical Society, 2010-09)
    In 2+1 dimensions at finite temperature, spontaneous symmetry breaking of global symmetries is precluded by large thermal fluctuations of the order parameter. The holographic correspondence implies that analogous effects ...
  • Bobev, Nikolay; Elvang, Henriette; Freedman, Daniel Z.; Pufu, Silviu (Springer-Verlag, 2014-07)
    We find the gravity dual of N = 2[superscript *] super-Yang-Mills theory on S [superscript 4] and use holography to calculate the universal contribution to the corresponding S [superscript 4] free energy at large N and ...
  • Freedman, Daniel Z.; Pufu, Silviu S. (Springer-Verlag/International School for Advanced Studies (SISSA), 2014-03)
    We find new supersymmetric backgrounds of N = 8 gauged supergravity in four Euclidean dimensions that are dual to deformations of ABJM theory on S 3. The deformations encode the most general choice of U(1) R symmetry used ...
  • Ferrari, Frank; Rovai, Antonin (Elsevier, 2015-06)
    In many instances of holographic correspondences between a d -dimensional boundary theory and a (d+1)-dimensional bulk, a direct argument in the boundary theory implies that there must exist a simple and precise relation ...
  • Sivarajah, Prasahnt; Teo, Stephanie M; Werley, Christopher A; Ofori-Okai, Benjamin Kwasi; Nelson, Keith Adam (IOP Publishing, 2015-01)
    Electromagnetic homogenization approximation calculates an effective refractive index of a composite material as a weighted average of its components, and has found uses in gradient refractive index and transformation ...
  • Schmuck, Markus; Bazant, Martin Z. (Society for Industrial and Applied Mathematics, 2015-06)
    Effective Poisson--Nernst--Planck (PNP) equations are derived for ion transport in charged porous media under forced convection (periodic flow in the frame of the mean velocity) by an asymptotic multiscale expansion with ...
  • Seidel, Paul (University Press Inc., 2010-01)
    We prove a form of Homological Mirror Symmetry for the genus two curve (on the symplectic or A-model side).
  • Liscombe, David K.; Usera, Aimee R.; O'Connor, Sarah Ellen (National Academy of Sciences (U.S.), 2010-11)
    Madagascar periwinkle (Catharanthus roseus) is the sole source of the anticancer drugs vinblastine and vincristine, bisindole alkaloids derived from the dimerization of the terpenoid indole alkaloids vindoline and ...
  • Sam, Steven V; Weyman, Jerzy; Snowden, Andrew WIlson (Springer-Verlag, 2013-02)
    Let V be a symplectic vector space of dimension 2n. Given a partition λ with at most n parts, there is an associated irreducible representation S[subscript [λ]](V) of Sp(V). This representation admits a resolution by a ...
  • Lin, Zhicong; Csikvari, Peter (Society for Industrial and Applied Mathematics, 2015-08)
    Let hom(G,H) denote the number of homomorphisms from a graph G to a graph H. In this paper we study the number of homomorphisms of trees into a path, and prove that hom(P[subscript m],P[subscript n]) ≤ hom(T[subscript ...
  • Alstott, Jeff; Madnick, Stuart E.; Velu, Chander (Public Library of Science, 2014-04)
    Large-scale mobilization of individuals across social networks is becoming increasingly prevalent in society. However, little is known about what affects the speed of social mobilization. Here we use a framed field experiment ...
  • Behrens, Mark Joseph; Davis, Daniel G. (American Mathematical Society, 2009-09)
    Let E be a k-local profinite G-Galois extension of an E1-ring spectrum A (in the sense of Rognes). We show that E may be regarded as producing a discrete G-spectrum. Also, we prove that if E is a profaithful k-local ...
  • Juels, Ari; Rivest, Ronald L. (Association for Computing Machinery (ACM), 2013-11)
    We propose a simple method for improving the security of hashed passwords: the maintenance of additional ``honeywords'' (false passwords) associated with each user's account. An adversary who steals a file of hashed passwords ...
  • Ge, Xuecai; Frank, Christopher Lee; Calderon de Anda, Froylan; Tsai, Li-Huei (Elsevier, 2010-01)
    Centrosome functions are important in many brain developmental processes. Proper functioning of the centrosome relies on assembly of protein components into the pericentriolar material. This dynamic assembly is mediated ...
  • Yazdani, Navid; List, Nancy B.; Hutchenson, Dwight K.; Royster, Thomas C., IV; Shoup, Ryan C. (Institute of Electrical and Electronics Engineers (IEEE), 2010-01)
  • Polz, Martin F.; Alm, Eric J.; Hanage, William P. (Elsevier, 2013-01)
    Many bacterial and archaeal lineages have a history of extensive and ongoing horizontal gene transfer and loss, as evidenced by the large differences in genome content even among otherwise closely related isolates. How ...
  • Aingaran, Mythili; Zhang, Rou; Law, Sue KaYee; Peng, Zhangli; Undisz, Andreas; Meyer, Evan; Diez Silva, Monica; Burke, Thomas A.; Spielmann, Tobias; Lim, Chwee Teck; Suresh, Subra; Dao, Ming; Marti, Matthias (Wiley-Blackwell Publishers, 2012-07)
    Gametocyte maturation in Plasmodium falciparum is a critical step in the transmission of malaria. While the majority of parasites proliferate asexually in red blood cells, a small fraction of parasites undergo sexual ...
  • Itoe, Maurice A.; Cabal, Ghislain G.; Real, Eliana; Zuzarte-Luis, Vanessa; Bhatia, Sangeeta N.; Frischknecht, Friedrich; Thiele, Christoph; Shevchenko, Andrej; Mota, Maria M.; Sampaio, Julio L.; March-Riera, Sandra; Bhatia, Sangeeta N. (Elsevier, 2014-12)
    During invasion, Plasmodium, the causative agent of malaria, wraps itself in a parasitophorous vacuole membrane (PVM), which constitutes a critical interface between the parasite and its host cell. Within hepatocytes, each ...
  • Park, Woon Ik; Kim, YongJoo; Jeong, Jae Won; Kim, Kyungho; Yoo, Jung-Keun; Hur, Yoon Hyung; Kim, Jong Min; Thomas, Edwin L.; Alexander-Katz, Alfredo; Jung, Yeon Sik (Nature Publishing Group, 2013-11)
    Ultrafine, uniform nanostructures with excellent functionalities can be formed by self-assembly of block copolymer (BCP) thin films. However, extension of their geometric variability is not straightforward due to their ...
