    • T-Branes and Monodromy 

      Cecotti, Sergio; Cordova, Clay Alexander; Heckman, Jonathan; Vafa, C. (Springer Verlag, 2011)
      We introduce T-branes, or "triangular branes," which are novel non-abelian bound states of branes characterized by the condition that on some loci, their matrix of normal deformations, or Higgs field, is upper triangular. ...
    • T-Lymphoblastic Lymphoma Cells Express High Levels of BCL2, S1P1, and ICAM1, Leading to a Blockade of Tumor Cell Intravasation 

      Feng, Hui; Stachura, David L.; White, Richard; Gutierrez, Alejandro; Zhang, Lu; Sanda, Takaomi; Jette, Cicely A.; Testa, Joseph R.; Neuberg, Donna S.; Langenau, David M.; Kutok, Jeffery Lorne; Zon, Leonard Ira; Traver, David; Fleming, Mark Daniel; Kanki, John P.; Look, A. Thomas (Elsevier BV, 2010)
      The molecular events underlying the progression of T-lymphoblastic lymphoma (T-LBL) to acute T-lymphoblastic leukemia (T-ALL) remain elusive. In our zebrafish model, concomitant overexpression of bcl-2 with Myc accelerated ...
    • Tables et index dans le livre de savoir en Europe moderne

    • Tail probabilities for triangular arrays 

      Fudenberg, Drew; Levine, David Saul (American Institute of Mathematical Sciences (AIMS), 2013)
      Di erent discrete time triangular arrays representing a noisy signal of players' activities can lead to the same limiting di usion process yet lead to di erent limit equilibria. Whether the limit equilibria are equilibria ...
    • Tail-Hedge Discounting and the Social Cost of Carbon 

      Weitzman, Martin L. (American Economic Association, 2013)
      The choice of an overall discount rate for climate change investments depends critically on how different components of investment payoffs are discounted at differing rates reflecting their underlying risk characteristics. ...
    • Tail-propelled aquatic locomotion in a theropod dinosaur 

      Ibrahim, Nizar; Maganuco, Simone; Dal Sasso, Cristiano; Fabbri, Matteo; Auditore, Marco; Bindellini, Gabriele; Martill, David; Zouhri, Samir; Mattarelli, Diego; Unwin, David; Wiemann, Jasmina; Bonadonna, Davide; Amane, Ayoub; Jakubczak, Juliana; Joger, Ulrich; Lauder, George; Pierce, Stephanie (Springer Science and Business Media LLC, 2020-04-29)
      Intensive research on non-avian dinosaurs in recent decades strongly suggests that these animals were restricted to terrestrial environments1. Historical views proposing that some groups, such as sauropods and hadrosaurs, ...
    • Tailoring Light-Matter Interaction with a Nanoscale Plasmon Resonator 

      de Leon, Nathalie Pulmones; Shields, Brendan John; Yu, Chun; Englund, Dirk E.; Akimov, Alexey; Lukin, Mikhail D.; Park, Hongkun (American Physical Society (APS), 2012)
      We propose and demonstrate a new approach for achieving enhanced light-matter interactions with quantum emitters. Our approach makes use of a plasmon resonator composed of defect-free, highly crystalline silver nanowires ...
    • Tailoring re-entrant geometry in inverse colloidal monolayers to control surface wettability 

      Utech, Stefanie; Bley, Karina; Aizenberg, Joanna; Vogel, Nicolas (Royal Society of Chemistry (RSC), 2016)
      Controlling the microscopic wetting state of a liquid in contact with a structured surface is the basis for the design of liquid repellent as well as anti-fogging coatings by preventing or enabling a given liquid to ...
    • Takeover Threats and Managerial Myopia 

      Stein, Jeremy C. (University of Chicago Press, 1988)
      This paper examines the familiar argument that takeover pressure can be damaging because it leads managers to sacrifice long-term interests in order to boost current profits. If stockholders are imperfectly informed, ...
    • Takeovers in the '60s and the '80s: Evidence and Implications 

      Shleifer, Andrei; Vishny, Robert W. (John Wiley and Sons, 1991)
      This paper reviews the evidence on takeover waves of the 1960s and 1980s, and discusses the implications of this evidence for corporate strategy, agency theory, capital market efficiency, and antitrust policy. We conclude ...
    • Taking Another Person’s Perspective Increases Self-Referential Neural Processing 

      Ames, Daniel L.; Jenkins, Adrianna C.; Banaji, Mahzarin; Mitchell, Jason (American Psychological Association / Blackwell Publishing Ltd., 2008)
    • Taking six-dimensional spectra in finite time 

      Goodknight, Joseph Sean Cahill; Aspuru-Guzik, Alan (American Association for the Advancement of Science (AAAS), 2017)
      Pump-probe spectroscopies use ultrafast laser pulses to excite molecules, and then probe them with a time-delayed pulse. If more laser pulses are used, information beyond excited-state spectra can be gained. For example, ...
    • Taking the Human Out of the Loop: A Review of Bayesian Optimization 

      Shahriari, Bobak; Swersky, Kevin; Wang, Ziyu; Adams, Ryan Prescott; de Freitas, Nando (Institute of Electrical & Electronics Engineers (IEEE), 2016)
      Big Data applications are typically associated with systems involving large numbers of users, massive complex software systems, and large-scale heterogeneous computing and storage architectures. The construction of such ...
    • Taking the Law into Our Own Hands: Kant on the Right to Revolution 

      Korsgaard, Christine (Oxford University Press, 2008)
      Kant condemned revolution as a violation of a duty of justice, yet was a supporter of the French Revolution. This chapter defends Kant's view that revolution is a violation of a duty of justice by appeal to the fact that ...
    • A Tale of Two Domes 

      Huang, Dennis; Hoffman, Jennifer Eve (American Physical Society (APS), 2016)
      Superconductivity describes the spectacular ability of electrons in some materials at low temperatures to form Cooper pairs and coherently carry charge without resistance. Creating superconductors that operate at room ...
    • A Tale of Two Frequencies: Determining the Speed of Lexical Access in Mandarin Chinese and English Compounds 

      Janssen, Niels; Bi, Yanchao; Caramazza, Alfonso (Taylor and Francis, 2008)
      Two picture naming experiments show that compound word production in Mandarin Chinese and in English is determined by the compound's whole-word frequency, and not by its constituent morpheme frequency. Four control experiments ...
    • A Tale of Two Secret Books 

      Russell, James R. (The Free Univeristy of Berlin and the Max Planck Institute, 2011)
    • A Tale of Two Tails: Peakedness Properties in Inheritance Models of Evolutionary Theory. 

      Ibragimov, Rustam (Springer International, 2008)
      In this paper, we study transmission of traits through generations in multifactorial inheritance models with sex- and time-dependent heritability. We further analyze the implications of these models under heavy-tailedness ...
