      Summary Transcription-factor-induced somatic cell conversions are highly relevant for both basic and clinical research yet their mechanism is not fully understood and it is unclear whether they reflect normal differentiation ...
    • C/o and Snowline Locations in Protoplanetary Disks: The Effect of Radial Drift and Viscous Gas Accretion 

      Piso, Ana-Maria Adriana; Oberg, Karin; Birnstiel, Tilman David; Murray-Clay, Ruth Ann (IOP Publishing, 2015)
      The C/O ratio is a defining feature of both gas giant atmospheric and protoplanetary disk chemistry. In disks, the C/O ratio is regulated by the presence of snowlines of major volatiles at different distances from the ...

      Cecchi-Pestellini, Cesare; Dalgarno, Alexander (Oxford University Press (OUP), 2002)
      The excitation of the diatomic carbon molecule in diffuse interstellar clouds is discussed for a cloud with large density fluctuations of small linear filling factor along the line of sight. Possible implications for the ...
    • C60-Propylamine Adduct Monolayers at the Gas/Water Interface: A Brewster Angle Microscopy and X-Ray Scattering Study 

      Fukumo, Masafumi; Penanen, Konstantin; Heilmann, Ralf K.; Pershan, Peter S.; Vaknin, David (American Institute of Physics, 1997)
      Brewster angle microscopy (BAM), x-ray specular reflectivity and grazing-incidence x-ray diffraction (GID) studies of C60-propylamine adduct monolayers at the gas/water interface as a function of molecular area are reported. ...
    • C9orf72 suppresses systemic and neural inflammation induced by gut bacteria 

      Burberry, Aaron; Wells, Michael; Limone, Francesco; Couto, Alexander; Smith, Kevin; Van Gastel, Nick; Wang, Jin-Yuan; Pietilainen, Olli; Qian, Menglu; Cantrell, Chris; Mok, Woon Jong Joanie; Scadden, David; Eggan, Kevin (Springer Science and Business Media LLC, 2020-05-13)
      A hexanucleotide repeat expansion in C9ORF72 is the most common genetic variant contributing to Amyotrophic lateral sclerosis (ALS) and Frontotemporal dementia (FTD)1,2. The C9ORF72 mutation acts through gain and loss of ...
    • Cache Craftiness for Fast Multicore Key-Value Storage 

      Mao, Yandong; Kohler, Edward W; Morris, Robert (Association for Computing Machinery, 2012)
      We present Masstree, a fast key-value database designed for SMP machines. Masstree keeps all data in memory. Its main data structure is a trie-like concatenation of \(B^+\)-trees, each of which handles a fixed-length slice ...
    • Cache-Fair Thread Scheduling for Multicore Processors 

      Fedorova, Alexandra; Seltzer, Margo I.; Smith, Michael D. (2006)
      We present a new operating system scheduling algorithm for multicore processors. Our algorithm reduces the effects of unequal CPU cache sharing that occur on these processors and cause unfair CPU sharing, priority inversion, ...
    • Cache-Oblivious Streaming B-Trees 

      Bender, Michael A.; Farach-Colton, Martin; Fineman, Jeremy T.; Fogel, Yonatan R.; Kuszmaul, Bradley C.; Nelson, Jelani (Association for Computer Machinery, 2007)
      A streaming B-tree is a dictionary that efficiently implements insertions and range queries. We present two cache-oblivious streaming B-trees, the shuttle tree, and the cache-oblivious lookahead array (COLA). For block-transfer ...
    • Cadden, Laqueur, and the "One-Sex Body" 

      Park, Katharine (Society for Medieval Feminist Scholarship, 2010)
    • Caesurae, Bridges, and the Colometry of Four Tocharian B Meters 

      Bross, Christoph; Ryan, Kevin M; Gunkel, Dieter (Brill Academic Publishers, 2014)
      The Tocharians composed verse in hierarchical structures, with the verse dominating major cola, and the major colon in turn dominating one or more minor cola. After providing much-needed descriptive data on Tocharian meter, ...
    • Calcified Metazoans in Thrombolite-stromatolite Reefs of the Terminal Proterozoic Nama Group, Namibia 

      Grotzinger, John P.; Watters, Wesley A.; Knoll, Andrew Herbert (Paleontological Society, 2000)
      Reefs containing abundant calcified metazoans occur at several stratigraphic levels within carbonate platforms of the terminal Proterozoic Nama Group, central and southern Namibia. The reef-bearing strata span an interval ...
    • Calcium Carbonate Storage in Amorphous Form and Its Template-Induced Crystallization† 

      Han, T. Yong-Jin; Aizenberg, Joanna (American Chemical Society (ACS), 2008)
      Calcium carbonate crystallization in organisms often occurs through the transformation from the amorphous precursor. It is believed that the amorphous phase could be temporarily stabilized and stored, until its templated ...

    • Calculating Standard Errors of Predicted Values Based on Nonlinear Functional Forms 

      King, Gary (The Society for Political Methodology, 1991)
      Whenever we report predicted values, we should also report some measure of the uncertainty of these estimates. In the linear case, this is relatively simple, and the answer well-known, but with nonlinear models the answer ...
