    • Axiomatization and Measurement of Quasi-Hyperbolic Discounting 

      Montiel Olea, J. L.; Strzalecki, Tomasz (Oxford University Press (OUP), 2014)
      This article provides an axiomatic characterization of quasi-hyperbolic discounting and a more general class of semi-hyperbolic preferences. We impose consistency restrictions directly on the intertemporal trade-offs by ...
    • Axion experiments to algebraic geometry — Testing quantum gravity via the Weak Gravity Conjecture 

      Heidenreich, Benjamin; Reece, Matthew; Rudelius, Tom (World Scientific Pub Co Pte Lt, 2016)
      Common features of known quantum gravity theories may hint at the general nature of quantum gravity. The absence of continuous global symmetries is one such feature. This inspired the Weak Gravity Conjecture, which bounds ...

    • Axionic Black Holes and an Aharonov-Bohm Effect for Strings 

      Bowick, Mark J.; Giddings, Steven B.; Harvey, Jeffrey A.; Horowitz, Gary T.; Strominger, Andrew (American Physical Society, 1988)
    • The Axis of Progression of Disease 

      Tartakoff, Alan M; Wu, Di (Libertas Academica, 2014)
      Starting with genetic or environmental perturbations, disease progression can involve a linear sequence of changes within individual cells. More often, however, a labyrinth of branching consequences emanates from the initial ...
    • AXIS: Generating Explanations at Scale with Learnersourcing and Machine Learning 

      Williams, Joseph Jay; Kim, Juho; Rafferty, Anna; Maldonado, Samuel; Gajos, Krzysztof Z; Lasecki, Walter; Heffernan, Neil (2016)
      While explanations may help people learn by providing information about why an answer is correct, many problems on online platforms lack high-quality explanations. This paper presents AXIS (Adaptive eXplanation Improvement ...
    • Azuchi Castle: Architectural Innovation and Political Legitimacy in Sixteenth-Century Japan 

      Erdmann, Mark Karl (2016-05-10)
      This study seeks to clarify the limits of knowledge regarding Azuchi Castle (Azuchi-jō) and, in turn, offers a multifaceted interpretation of its crowning glory―the six-story, lavishly decorated, timber-framed tower known ...
    • B cell homeostasis and follicle confines are governed by fibroblastic reticular cells 

      Cremasco, Viviana; Woodruff, Matthew C.; Onder, Lucas; Cupovic, Jovana; Nieves-Bonilla, Janice M.; Schildberg, Frank A.; Chang, Jonathan; Cremasco, Floriana; Harvey, Christopher J.; Wucherpfennig, Kai; Ludewig, Burkhard; Carroll, Michael C.; Turley, Shannon J. (2014)
      Fibroblastic reticular cells (FRCs) are known to inhabit T cell-rich areas of lymphoid organs where they function to coordinate T cell and dendritic cell interactions. However, in vivo manipulation of FRCs has been limited ...
    • B-MYB and FOXM1 drive cell division through cooperative regulation of cell cycle genes. 

      Rivas, Hembly (2024-03-12)
      Transcription facilitates cell cycle division and progression as it orchestrates the timely expression of genes crucial for each cell cycle phase. Two waves of gene expression prime the cell for replication: the first wave ...
    • Baby Universes and String Theory 

      Dijkgraaf, Robbert; Gopakumar, Rajesh; Ooguri, Hirosi; Vafa, Cumrun (American Physical Society, 2006)
      The description of 4D BPS black holes in terms of branes wrapped on various cycles in a Calabi-Yau space gives us the opportunity to study various issues in quantum gravity in a definite way by means of the worldvolume ...
    • Bacillus spores as building blocks for stimuli-responsive materials and nanogenerators 

      Chen, Xi; Mahadevan, Lakshminarayanan; Driks, Adam; Sahin, Ozgur (Nature Publishing Group, 2014)
    • Back to the Drawing Board: Ed Ruscha 1956 – 68 

      Quick, Jennifer Eileen (2015-05-15)
      This dissertation considers Ed Ruscha’s work through the theoretical lens of tacit knowledge, thereby making the argument that the commercial artist’s drawing board, and the world that it embodies, constitutes the material ...
    • Back to the future 

      Rosenberg, Charles (Elsevier BV, 2013)
    • Background ozone over the United States in summer: Origin, trend, and contribution to pollution episodes 

      Fiore, Arlene M.; Jacob, Daniel James; Bey, Isabelle; Yantosca, Robert M.; Field, Brendan; Fusco, Andrew; Wilkinson, James (Wiley-Blackwell, 2002)
      Observations indicate that ozone (O3) concentrations in surface air over the United States in summer contain a 20–45 ppbv background contribution, presumably reflecting transport from outside the North American boundary ...
    • Backward Raising 

      Potsdam, Eric; Polinsky, Maria (Wiley Blackwell (Blackwell Publishing), 2012)
      This paper documents and analyzes an instance of covert A-movement, specifically covert subject-to-subject raising, in the Northwest Caucasian language Adyghe. We argue that Adyghe has a subject-to-subject raising ...
    • Bacteria activate sensory neurons that modulate pain and inflammation 

      Chiu, Isaac M.; Heesters, Balthasar A.; Ghasemlou, Nader; Von Hehn, Christian A.; Zhao, Fan; Tran, Johnathan; Wainger, Brian; Strominger, Amanda; Muralidharan, Sriya; Horswill, Alexander R.; Wardenburg, Juliane Bubeck; Hwang, Sun Wook; Carroll, Michael C.; Woolf, Clifford J. (2013)
      Summary Nociceptor sensory neurons are specialized to detect potentially damaging stimuli, protecting the organism by initiating the sensation of pain and eliciting defensive behaviors. Bacterial infections produce pain ...
    • Bacteria Pattern Spontaneously on Periodic Nanostructure Arrays 

      Hochbaum, Allon I.; Aizenberg, Joanna (American Chemical Society (ACS), 2010)
      Surface-associated bacteria typically form self-organizing communities called biofilms. Spatial segregation is important for various bacterial processes associated with cellular and community development. Here, we demonstrate ...
