  • Acemoglu, Daron; Gancia, Gino; Zilibotti, Fabrizio (Elsevier ScienceDirect, 2010-09)
    We study a dynamic general equilibrium model where innovation takes the form of the introduction of new goods whose production requires skilled workers. Innovation is followed by a costly process of standardization, whereby ...
  • Kushima, Akihiro; Yildiz, Bilge; Yip, Sidney (American Physical Society, 2010-09)
    Planar strain effects on oxygen-vacancy formation and oxygen adsorption on LaCoO[subscript 3] are shown to manifest through competing mechanisms. Through first-principles calculations, we demonstrate that these unit processes ...
  • Gorbenko, Alexander S.; Malenko, Andrey (American Economic Association, 2011-08)
    We study simultaneous security-bid second-price auctions with competition among sellers for potential bidders. The sellers compete by designing ordered sets of securities that the bidders can offer as payment for the assets. ...
  • Korolev, Kirill Sergeevich; Nelson, David R. (American Physical Society, 2011-08)
    Mutualism is a major force driving evolution and sustaining ecosystems. Although the importance of spatial degrees of freedom and number fluctuations is well known, their effects on mutualism are not fully understood. With ...
  • Ciudad, David; Arena, D. A.; Han, X.-F.; Hindmarch, A. T.; Marrows, C. H.; Negusse, E.; Wen, Z.-C. (American Physical Society, 2012-06)
    The transition between Kondo and Coulomb blockade effects in discontinuous double magnetic tunnel junctions is explored as a function of the size of the CoPt magnetic clusters embedded between AlO[subscript x] tunnel ...
  • Pekker, David; Babadi, Mehrtash; Sensarma, Rajdeep; Zinner, Nikolaj; Pollet, Lode; Zwierlein, Martin Wolfram; Demler, Eugene (American Physical Society, 2011-02)
    We study the quench dynamics of a two-component ultracold Fermi gas from the weak into the strong interaction regime, where the short time dynamics are governed by the exponential growth rate of unstable collective modes. ...
  • Avalos, Ana M.; Ploegh, Hidde (Wiley Blackwell, 2011-10)
    TLR9 recognizes unmethylated CpG-containing DNA commonly found in bacteria. Synthetic oligonucleotides containing CpG-motifs (CpG ODNs) recapitulate the activation of TLR9 by microbial DNA, whereas inversion of the CG ...
  • Lopez, Carla M.; Pelkey, Kenneth A.; Chittajallu, Ramesh; Nakashiba, Toshiaki; Toth, Katalin; Tonegawa, Susumu; McBain, Chris J. (Frontiers Research Foundation, 2012-11)
    In the developing nervous system synaptic refinement, typified by the neuromuscular junction where supernumerary connections are eliminated by axon retraction leaving the postsynaptic target innervated by a single dominant ...
  • Martinez-de-Albeniz, Victor; Simchi-Levi, David (Institute for Operations Research and the Management Sciences, 2009-09)
    This paper develops a multiattribute competition model for procurement of short life-cycle products. In such an environment, the buyer installs dedicated production capacity at the suppliers before demand is realized. Final ...
  • Njoroge, Paul; Ozdaglar, Asuman E.; Stier, Nicolas; Weintraub, Gabriel (2009-07)
    We study duopoly competition between two interconnected Internet Service Providers (ISP) that compete in quality and prices for both Content Providers (CP) and consumers. We develop a game theoretic model using a two-sided ...
  • Rutishauser, Ueli; Slotine, Jean-Jacques E.; Douglas, Rodney J. (MIT Press, 2012-06)
    Models of cortical neuronal circuits commonly depend on inhibitory feedback to control gain, provide signal normalization, and selectively amplify signals using winner-take-all (WTA) dynamics. Such models generally assume ...
  • Zuhl, Andrea M.; Mohr, Justin T.; Bachovchin, Daniel A.; Niessen, Sherry; Hsu, Ku-Lung; Berlin, Jacob M.; Dochnahl, Maximilian; Fu, Gregory C.; Cravatt, Benjamin F.; Lopez-Alberca, Maria P. (American Chemical Society (ACS), 2012-03)
    Serine hydrolases are one of the largest and most diverse enzyme classes in Nature. Most serine hydrolases lack selective inhibitors, which are valuable probes for assigning functions to these enzymes. We recently discovered ...
  • Aich, Udayanath; Shriver, Zachary H.; Tharakaraman, Kannan; Raman, Rahul; Sasisekharan, Ram (American Chemical Society, 2011-08)
    Heparin and the low molecular weight heparins are extensively used as medicinal products to prevent and treat the formation of venous and arterial thrombi. In early 2008, administration of some heparin lots was associated ...
  • Parrilo, Pablo A.; Candogan, Utku Ozan; Menache, Ishai; Ozdaglar, Asuman E. (Institute of Electrical and Electronics Engineers, 2009-06)
    We consider a wireless collision channel, shared by a finite number of mobile users who transmit to a common base station. Each user wishes to optimize its individual network utility that incorporates a natural tradeoff ...
  • Schneider, Ben Ross; Karcher, Sebastian (Oxford University Press and the Society for the Advancement of Socio-Economics, 2010-10)
    In a comparative institutional or ‘variety of capitalism’ perspective, the distinctive traits of labour markets in Latin America differ in most respects from labour markets in developed countries. Moreover, there are strong ...
  • Ruppin, F.; Strigari, L.; Billard, Julien; Figueroa-Feliciano, Enectali (American Physical Society, 2014-10)
    Direct detection dark matter experiments looking for WIMP-nucleus elastic scattering will soon be sensitive to an irreducible background from neutrinos which will drastically affect their discovery potential. Here we explore ...
  • Ahmadi, Amir Ali; Parrilo, Pablo A. (Society for Industrial and Applied Mathematics, 2013-05)
    Our first contribution in this paper is to prove that three natural sum of squares (sos) based sufficient conditions for convexity of polynomials, via the definition of convexity, its first order characterization, and its ...
  • Chen, Xie; Gu, Zheng-Cheng; Wen, Xiao-Gang (American Physical Society, 2011-12)
    Quantum phases with different orders exist with or without breaking the symmetry of the system. Recently, a classification of gapped quantum phases which do not break time reversal, parity, or on-site unitary symmetry has ...
  • Bronson, R T; Haigis, K M; Cheung, Ann; Carter, Alia; Kostova, Kamena K.; Woodruff, Joe; Crowley, Denise G.; Jacks, Tyler E. (Nature Publishing Group, 2009-12)
    The adenomatous polyposis coli (APC) gene product is mutated in the vast majority of human colorectal cancers. APC negatively regulates the WNT pathway by aiding in the degradation of β-catenin, which is the transcription ...
  • Smith, Janet L.; Goldberg, Jonathan M.; Grossman, Alan D. (American Society for Microbiology, 2014-07)
    The Gram-positive bacterium Bacillus subtilis is widely used for studies of cellular and molecular processes. We announce the complete genomic sequences of strain AG174, our stock of the commonly used strain JH642, and ...
