    • The Global Lettered City: Humanism and Empire in Colonial Latin America and the Early Modern World 

      McManus, Stuart Michael (2016-05-10)
      Historians have long recognized the symbiotic relationship between learned culture, urban life and Iberian expansion in the creation of “Latin” America out of the ruins of pre-Columbian polities, a process described most ...

    • Global Lifetime of Elemental Mercury Against Oxidation by Atomic Bromine in the Free Troposphere 

      Holmes, Christopher; Jacob, Daniel J.; Yang, Xin (American Geophysical Union, 2006)
      We calculate the global mean atmospheric lifetime of elemental mercury (Hg0) against oxidation by atomic bromine (Br) in the troposphere by combining recent kinetic data for the Hg-Br system with modeled global concentrations ...

    • A Global Model for Forecasting Political Instability 

      Goldstone, Jack A.; Bates, Robert H.; Epstein, David L.; Gurr, Ted Robert; Lustik, Michael B.; Marshall, Monty G.; Ulfelder, Jay; Woodward, Mark (Wiley Blackwell (Blackwell Publishing), 2010)
      Examining onsets of political instability in countries worldwide from 1955 to 2003, we develop a model that distinguishes countries that experienced instability from those that remained stable with a two-year lead time and ...

    • Global Modeling of Persistent Organic Pollutants in an Era of Changing Emissions and Climate 

      Wagner, Charlotte (2021-07-12)
      Certain anthropogenic organic pollutants persist in the environment, bioaccumulate and are toxic to humans and wildlife. They accumulate in the global oceans where marine biogeochemical cycles drive their fate and distribution. ...

      Henze, D. K.; Seinfeld, J. H.; Ng, N. L.; Kroll, J. H.; Fu, Tian-Ming; Jacob, Daniel J.; Heald, C. L. (European Geosciences Union, 2008)
      Formation of SOA from the aromatic species toluene, xylene, and, for the first time, benzene, is added to a global chemical transport model. A simple mechanism is presented that accounts for competition between low and ...

    • Global modeling of tropospheric chemistry with assimilated meteorology: Model description and evaluation 

      Bey, Isabelle; Jacob, Daniel James; Yantosca, Robert M.; Logan, Jennifer A.; Field, Brendan D.; Fiore, Arlene M.; Li, Qinbin; Liu, Honguy Y.; Mickley, Loretta J.; Schultz, Martin G. (Wiley-Blackwell, 2001)
      We present a first description and evaluation of GEOS-CHEM, a global threedimensional (3-D) model of tropospheric chemistry driven by assimilated meteorological observations from the Goddard Earth Observing System (GEOS) ...

    • Global modelling of the early martian climate under a denser \(CO_2\) atmosphere: Water cycle and ice evolution 

      Wordsworth, Robin; Forget, F.; Millour, E.; Head, J.W.; Madeleine, J.-B.; Charnay, B. (Elsevier BV, 2013)
      We discuss 3D global simulations of the early martian climate that we have performed assuming a faint young Sun and denser CO2 atmosphere. We include a self-consistent representation of the water cycle, with atmosphere–surface ...

    • Global Nucleosome Occupancy in Yeast 

      Bernstein, Bradley E.; Liu, Chih Long; Humphrey, Emily L; Perlstein, Ethan O; Schreiber, Stuart L. (BioMed Central, 2004)
      A genome-wide study of nucleosome occupancy at yeast promoters shows that promoters that regulate active genes, contain multiple conserved motifs, or contain Rap1 binding sites tend to be depleted of nucleosomes.

    • Global Operations For Protected Quantum Memories In Atomic Spin Lattices 

      Brennen, Gavin K.; Hammerer, Klemens; Jiang, Liang; Lukin, Mikhail D.; Zoller, Peter (2009)
      Quantum information processed in strongly correlated states of matter can provide built in hardware protection against errors. We may encode information in highly non local degrees of freedom, such as using three dimensional ...

    • Global Ozone–CO Correlations from OMI and AIRS: Constraints on Tropospheric Ozone Sources 

      Kim, Philip; Jacob, Daniel James; Liu, Xueliang; Warner, J. X.; Yang, K.; Chance, Kelly V.; Thouret, V.; Nedelec, P. (European Geosciences Union, 2013)
      We present a global data set of free tropospheric ozone–CO correlations with 2° × 2.5° spatial resolution from the Ozone Monitoring Instrument (OMI) and Atmospheric Infrared Sounder (AIRS) satellite instruments for each ...

    • Global patterns of water storage in the rooting zones of vegetation 

      Stocker, Benjamin D.; Tumber-Dávila, Shersingh Joseph; Konings, Alexandra G.; Anderson, Martha B.; Hain, Christopher; Jackson, Robert B.; Tumber (Springer Science and Business Media LLC, 2023-02-09)
      <jats:title>Abstract</jats:title><jats:p>The rooting-zone water-storage capacity—the amount of water accessible to plants—controls the sensitivity of land–atmosphere exchange of water and carbon during dry periods. How the ...

    • Global Phase Diagrams of Frustrated Quantum Antiferromagnets in Two Dimensions: Doubled Chern-Simons Theory 

      Xu, Cenke; Sachdev, Subir (The American Physical Society, 2009)
      We present a general approach to understanding the quantum phases and phase transitions of quantum antiferromagnets in two spatial dimensions. We begin with the simplest spin liquid state, the \(Z_2\) spin liquid, whose ...

      Wong, John (2012-07-23)
      This study unearths the lost world of early-nineteenth-century Canton. Known today as Guangzhou, this Chinese city witnessed the economic dynamism of global commerce until the demise of the Canton System in 1842. Records ...

    • Global post-transcriptional regulators in Pseudomonas aeruginosa 

      Kambara, Tracy K. (2018-08-17)
