    • Cyclotomic Factors of Coxeter Polynomials 

      Gross, Benedict H.; Hironaka, Eriko; McMullen, Curtis T. (Elsevier, 2009)
      In this paper we show that the cyclotomic factors of the En Coxeter polynomials depend only on the value of \(n\) mod 360, and come exclusively from spherical subdiagrams.
    • Cyfarwydd as Poet in the Fourth Branch of the Mabinogi 

      McKenna, Catherine (The Ohio State University Press, 2017)
      On two occasions in the Fourth Branch of the Mabinogi , the figure of Gwydion presents himself in a court as a poet and provides entertainment, presumably in prose, in the form of cyfarwyddyd , a term that has been variously ...
    • Cylindrocyclophane Biosynthesis Involves Functionalization of an Unactivated Carbon Center 

      Nakamura, Hitomi; Hamer, Hilary Ann; Sirasani, Gopal; Balskus, Emily Patricia (American Chemical Society, 2012)
      The cylindrocyclophanes are a family of natural products that share a remarkable paracyclophane carbon scaffold. Using genome sequencing and bioinformatic analyses, we have discovered a biosynthetic gene cluster involved ...
    • Cytoplasmic Diffusion: Molecular Motors Mix It Up 

      Brangwynne, Clifford P.; Koenderink, Gijsje H.; MacKintosh, Frederick C.; Weitz, David A. (The Rockefeller University Press, 2008)
      Random motion within the cytoplasm gives rise to molecular diffusion; this motion is essential to many biological processes. However, in addition to thermal Brownian motion, the cytoplasm also undergoes constant agitation ...
    • Cytoprotective Pathways that Contribute to Lifespan Extension in C. elegans 

      Shore, David (2013-02-11)
      Stress tolerance and lifespan are intimately associated. Extension of lifespan is accompanied by increased tolerance of heat, oxidative stress, radiation and other stressors, while genetic perturbations that abrogate ...
    • C–H Functionalization Catalysis via Transition Metal Stabilized Ligand-Based Radicals 

      Dong, Yuyang (2021-04-23)
      Two catalytic systems exploiting the capability of introducing functionalities into C–H bonds using transition metal stabilized ligand-based radicals were explored. The first system utilizes sterically accessible bidentate ...
    • D,L-Cyclic Peptides as Structural Materials 

      Rubin, Daniel James (2015-04-17)
      The bioengineer has a choice of building with proteins, peptides, polymers, nucleic acids, lipids, metals and minerals, each class containing tremendous diversity within its category. While the platforms are diverse, they ...
    • D--branes and Spinning Black Holes 

      Breckenridge, Jason; Myers, Robert; Peet, Amanda; Vafa, Cumrun (Elsevier, 1996)
      We obtain a new class of spinning charged extremal black holes in five dimensions, considered both as classical configurations and in the Dirichlet (D)-brane representation. The degeneracy of states is computed from the ...
    • D-Amino Acids Indirectly Inhibit Biofilm Formation in Bacillus subtilis by Interfering with Protein Synthesis 

      Leiman, Sara A; May, J. M.; Lebar, M. D.; Kahne, Daniel; Kolter, R.; Losick, Richard M. (American Society for Microbiology, 2013)
      The soil bacterium Bacillus subtilis forms biofilms on surfaces and at air-liquid interfaces. It was previously reported that these biofilms disassemble late in their life cycle and that conditioned medium from late-stage ...
    • D-brane Construction of the 5D NHEK Dual 

      Song, Wei; Strominger, Andrew E. (Springer-Verlag, 2012)
      Extremal but non-supersymmetric charged black holes with \(SU(2)_L\) spin in IIB string theory compactified to five dimensions on \(K^3 \times S^1\) are considered. These have a near-horizon or NHEK region with an enhanced ...
    • D-brane Deconstructions in IIB Orientifolds 

      Collinucci, Andres; Denef, Frederik; Esole, Mboyo (Institute of Physics, 2009)
      With model building applications in mind, we collect and develop basic techniques to analyze the landscape of D7-branes in type IIB compact Calabi-Yau orientifolds, in three different pictures: F-theory, the D7 worldvolume ...
    • D-helix influences dimerization of the ATP-binding cassette (ABC) transporter associated with antigen processing 1 (TAP1) nucleotide-binding domain 

      Vakkasoglu, Ahmet; Srikant, Sriram; Gaudet, Rachelle (Public Library of Science (PLoS), 2017)
      ATP-binding cassette (ABC) transporters form a large family of transmembrane importers and exporters. Using two nucleotide-binding domains (NBDs), which form a canonical ATP-sandwich dimer at some point within the transport ...
    • D-instantons and String Field Theory 

      Agmon, Nathan Benjamin (2023-05-12)
      In this thesis, we study D-instanton contributions to supergraviton scattering amplitudes in ten-dimensional type IIB superstring theory beyond the leading non-perturbative order. Our computation is based on the ...
    • D-modules and finite monodromy 

      Esnault, Hélène; Kisin, Mark (Springer Nature, 2016)
      We investigate an analogue of the Grothendieck p-curvature conjecture, where the vanishing of the p-curvature is replaced by the stronger condition, that the module with connection mod p underlies a XDX -module structure. ...
    • D-Modules on Spaces of Rational Maps and on Other Generic Data 

      Barlev, Jonathan (2012-12-13)
      Fix an algebraic curve X. We study the problem of parametrizing geometric data over X, which is only generically defined. E.g., parametrizing generically defined maps from X to a fixed target scheme Y. There are three methods ...
    • D-Modules on the Affine Flag Variety and Representations of Affine Kac-Moody Algebras 

      Frenkel, Edward; Gaitsgory, Dennis (American Mathematical Society, 2009)
      The present paper studies the connection between the category of modules over the affine Kac-Moody Lie algebra at the critical level, and the category of D-modules on the affine flag scheme \(G((t))/I\), where \(I\) is the ...
    • D-π-A Dye System Containing Cyano-Benzoic Acid as Anchoring Group for Dye-Sensitized Solar Cells 

      Katono, Masataka; Bessho, Takeru; Meng, Sheng; Humphry-Baker, Robin; Rothenberger, Guido; Zakeeruddin, Shaik M.; Kaxiras, Efthimios; Grätzel, Michael (American Chemical Society, 2011)
    • The \(D_4\) Root System is Not Universally Optimal 

      Cohn, Henry; Conway, John H.; Elkies, Noam; Kumar, Abhinav (AK Peters, 2007)
      We prove that the \(D_4\) root system (equivalently, the set of vertices of the regular 24-cell) is not a universally optimal spherical code. We further conjecture that there is no universally optimal spherical code of 24 ...
