      We compare eight pollen records reflecting climatic and environmental change from northern and southern sites in the tropical Andes. Our analysis focuses on the last 30 000 years, with particular emphasis on the Pleistocene ...
    • mioC transcription, initiation of replication, and the eclipse in Escherichia coli 

      Bogan, Joseph A.; Helmstetter, Charles E. (1996-04)
      The potential role of mioC transcription as a negative regulator of initiation of chromosome replication in Escherichia coli was evaluated. When initiation was aligned by a shift of dnaC2(Ts) mutants to nonpermissive ...
    • Morphology predicts suction feeding performance in centrarchid fishes 

      Carroll, Andrew M.; Wainwright, Peter C.; Huskey, Stephen H.; Collar, David C.; Turingan, Ralph G. (2004-10)
      Suction feeding fish differ in their capacity to generate subambient pressure while feeding, and these differences appear to relate to morphological variation. We developed a morphological model of force transmission in ...

    • A NEW METHOD FOR IMPROVED FIXATION OF THE CHICK'S INNER EAR 

      Otto, Joseph V.; Park, Janie C.; Fermin, Cesar D.; Cohen, Glenn M. (1984)
      Our method for fixation of the chick's inner ear involves puncturing the soft temporal bone with a needle and directly flushing the membranous labyrinth with cold glutaraldehyde. The temporal bone is trimmed and immersed ...
    • nGASP - The nematode genome annotation assessment project 

      Coghlan, Avril; Fiedler, Tristan J.; McKay, Sheldon J.; Flicek, Paul R.; Harris, Todd W.; Blasiar, Darin; Stein, Lincoln D. (2008-12-19)
      Background: While the C. elegans genome is extensively annotated, relatively little information is available for other Caenorhabditis species. The nematode genome annotation assessment project (nGASP) was launched to ...

    • Numerical investigations of tip clearance flow characteristics of a pumpjet propulsor 

      Lu, Lin; Gao, Yuefei; Li, Qiang; Du, Lin (2018)
      In this study, numerical investigations of the tip clearance flow characteristics of a pumpjet propulsor based on Computational Fluid Dynamics (CFD) method have been presented. The Zwart-Gerber-Belamri (Z-G-B) cavitation ...
    • Numerical simulation of tip clearance impact on a pumpjet propulsor 

      Lu, Lin; Pan, Guang; Wei, Jing; Pan, Yipeng (2016-05)
      Numerical simulation based on the Reynolds Averaged NaviereStokes (RANS) Computational Fluid Dynamics (CFD) method had been carried out with the commercial code ANSYS CFX. The structured grid and SST k-ω turbulence model ...
    • The orisome: structure and function 

      Grimwade, Julia E.; Leonard, Alan C. (2015-06-02)
      During the cell division cycle of all bacteria, DNA-protein complexes termed orisomes trigger the onset of chromosome duplication. Orisome assembly is both staged and stringently regulated to ensure that DNA synthesis ...
    • Overexpression of TIMP-3 in chondrocytes produces transient reduction in growth plate length but permanently reduces adult bone quality and quantity 

      Poulet, Blandine; Liu, Ke; Plumb, Darren A.; Vo, Phoung; Shah, Mittal; Staines, Katherine Ann; Sampson, Alexandra; Nakamura, Hiroyuki; Nagase, Hideaki; Carriero, Alessandra (2016-12-21)
      Bone development and length relies on the growth plate formation, which is dependent on degradative enzymes such as MMPs. Indeed, deletion of specific members of this enzyme family in mice results in important joint and ...
    • Persistence and change in community composition of reef corals through present, past, and future climates 

      van Woesik, Robert; Edmunds, Peter J.; Adjeroud, Mehdi; Baskett, Marissa L.; Baums, Iliana B.; Budd, Ann F.; Carpenter, Robert C. C.; Fabina, Nicholas S.; Fan, Tungyung; Franklin, Erik C. (2014-10-01)
      The reduction in coral cover on many contemporary tropical reefs suggests a different set of coral community assemblages will dominate future reefs. To evaluate the capacity of reef corals to persist over various time ...
    • Phase shifts and stable states on coral reefs 

      Dudgeon, Steve R.; Aronson, Richard B.; Bruno, John F.; Precht, William F. (2010-08-26)
      Recent transitions from coral to macroalgal dominance on some tropical reefs have engendered debate about their causes and effects. A widely accepted view is that reef environments support stable, alternative coral or ...
    • Phenotypic variance predicts symbiont population densities in corals: A modeling approach 

      van Woesik, Robert; Shiroma, Kazuyo; Köksal, Semen (2010-02-12)
      We test whether the phenotypic variance of symbionts (Symbiodinium) in corals is closely related with the capacity of corals to acclimatize to increasing seawater temperatures. Moreover, we assess whether more specialist ...
    • Photographic survey of benthos provides insights into the Antarctic fish fauna from the Marguerite Bay slope and the Amundsen Sea 

      Eastman, Joseph T.; Amsler, Margaret O.; Aronson, Richard B.; Thatje, Sven; McClintock, James B.; Vos, Stephanie C.; Kaeli, Jeffrey W.; Singh, Hanumant; Mesa, Mario La (2012-10-09)
      We reviewed photographic images of fishes from depths of 381–2282 m in Marguerite Bay and 405–2007 m in the Amundsen Sea. Marguerite Bay fishes were 33% notothenioids and 67% non-notothenioids. Channichthyids (47%) and ...
