  • Barkeshli, Maissam; Wen, Xiao-Gang (American Physical Society, 2010-12)
    A large class of fractional quantum Hall (FQH) states can be classified according to their pattern of zeros, which describes the way ideal ground-state wave functions go to zero as various clusters of electrons are brought ...
  • Boyallian, Carina; Liberati, José I.; Kac, Victor (Springer-Verlag, 2012-11)
    We classify all continuous degenerate irreducible modules over the exceptional linearly compact Lie superalgebra E(1, 6), and all finite degenerate irreducible modules over the exceptional Lie conformal superalgebra ...
  • Chen, Xie; Gu, Zheng-Cheng; Wen, Xiao-Gang (American Physical Society, 2011-01)
    Quantum many-body systems divide into a variety of phases with very different physical properties. The questions of what kinds of phases exist and how to identify them seem hard, especially for strongly interacting systems. ...
  • Wang, Chong; Potter, Andrew C.; Todadri, Senthil (American Association for the Advancement of Science (AAAS), 2014-02)
    A fundamental open problem in condensed-matter physics is how the dichotomy between conventional and topological band insulators is modified in the presence of strong electron interactions. We show that there are six ...
  • Cantarini, Nicoletta; Kac, Victor (Springer-Verlag, 2010-04)
    We classify simple linearly compact n-Lie superalgebras with n > 2 over a field F of characteristic 0. The classification is based on a bijective correspondence between non-abelian n-Lie superalgebras and transitive Z-graded ...
  • Gu, Zheng-Cheng; Wang, Zhenghan; Wen, Xiao-Gang (American Physical Society, 2015-03)
    The string-net approach by Levin and Wen, and the local unitary transformation approach by Chen, Gu, and Wen, provide ways to classify topological orders with gappable edge in two-dimensional (2D) bosonic systems. The two ...
  • Varshney, Kush R.; Willsky, Alan S. (Association for Computing Machinery (ACM), 2010-02)
    A variational level set method is developed for the supervised classification problem. Nonlinear classifier decision boundaries are obtained by minimizing an energy functional that is composed of an empirical risk term ...
  • Morrison, David R.; Taylor, Washington (Versita (Central European Science Journals), 2012-10)
    We classify six-dimensional F-theory compactifications in terms of simple features of the divisor structure of the base surface of the elliptic fibration. This structure controls the minimal spectrum of the theory. We ...
  • Wen, Xiao-Gang (American Physical Society, 2013-08)
    In this paper, we systematically study gauge anomalies in bosonic and fermionic weak-coupling gauge theories with gauge group G (which can be continuous or discrete) in d space-time dimensions. We show a very close relation ...
  • Singh, Vivek Kumar; Freeman, Laura; Lepri, Bruno; Pentland, Alex Paul (Academy of Science and Engineering, 2013-06)
    Human spending behavior is essentially social. This work motivates and grounds the use of mobile phone based social interaction features for classifying spending behavior. Using a data set involving 52 adults (26 couples) ...
  • Wei, Yifeng; Funk, Michael Andrew; Rosado, Leonardo A.; Baek, Jiyeon; Drennan, Catherine L.; Stubbe, JoAnne (National Academy of Sciences (U.S.), 2014-08)
    The class III anaerobic ribonucleotide reductases (RNRs) studied to date couple the reduction of ribonucleotides to deoxynucleotides with the oxidation of formate to CO[subscript 2]. Here we report the cloning and heterologous ...
  • Costantino, Cristina Maria; Hafler, David A.; Spooner, Eric; Ploegh, Hidde (Public Library of Science, 2012-01)
    Human CD4[superscript +] T cells process and present functional class II MHC-peptide complexes, but the endogenous peptide repertoire of these non-classical antigen presenting cells remains unknown. We eluted and sequenced ...
  • Cavicchi, Elizabeth (Springer Science+Business Media, 2011-02)
    What do you see in a mirror when not looking at yourself? What goes on as a pendulum swings? Undergraduates in a science class supposed that these behaviors were obvious until their explorations exposed questions with no ...
  • Chiu, Han-Pang; Liu, Huan; Kaelbling, Leslie P.; Lozano-Perez, Tomas (Institute of Electrical and Electronics Engineers, 2010-12)
    Our goal is to grasp 3D objects given a single image, by using prior 3D shape models of object classes. The shape models, defined as a collection of oriented primitive shapes centered at fixed 3D positions, can be learned ...
  • Grunwald, Stephan; Mottet, Alexis; Grousseau, Estelle; Plassmeier, Jens K.; Uribelarrea, Jean-Louis; Gorret, Nathalie; Sinskey, Anthony J.; Popovic, Milan K.; Guillouet, Stephane E. (Wiley Blackwell, 2014-08)
    Formic acid, acting as both carbon and energy source, is a safe alternative to a carbon dioxide, hydrogen and dioxygen mix for studying the conversion of carbon through the Calvin–Benson–Bassham (CBB) cycle into value-added ...
  • Bazant, Martin Z. (American Physical Society, 2010-02)
    Experiments now quantitatively confirm the standard model of electrokinetics, in which electric fields drive the flow of electrolytes, potentially leading to better sensors and biomedical diagnostic devices.
  • Gollakota, Shyamnath; Adib, Fadel M.; Katabi, Dina; Seshan, Srinivasan (Association for Computing Machinery, 2011-08)
    Recent studies show that high-power cross-technology interference is becoming a major problem in today’s 802.11 networks. Devices like baby monitors and cordless phones can cause a wireless LAN to lose connectivity. The ...
  • Swager, Timothy Manning; Liu, Shuang; Muller, Peter; Takase, Michael K. (American Chemical Society (ACS), 2011-07)
    Efficient synthesis of heteroleptic tris-cyclometalated Ir(III) complexes mer-Ir(C/\N)[subscript 2](trpy) (trpy = 2-(1H-[1,2,3]triazol-4-yl)pyridine) is achieved by using the Cu(I)-triazolide intermediates formed in “click” ...
  • Deschenes, Oliver; Greenstone, Michael; Guryan, Jonathan (American Economic Association, 2009-05)
    There is a growing consensus that emissions of greenhouse gases due to human activity will alter the earth’s climate, most notably by causing temperatures, precipitation levels, and weather variability to increase. The ...
  • Zhang, Yanxu; Friedman, Carey; Selin, Noelle Eckley (American Chemical Society (ACS), 2013-11)
    We investigate effects of 2000–2050 emissions and climate changes on the atmospheric transport of three polycyclic aromatic hydrocarbons (PAHs): phenanthrene (PHE), pyrene (PYR), and benzo[a]pyrene (BaP). We use the GEOS-Chem ...
