    • An Epithelial-Mesenchymal Gene Regulatory Network that Controls Tooth Organogenesis 

      O'Connell, Daniel Joseph (2013-02-25)
      Many vertebrate organs form via the sequential, reciprocal exchange of signaling molecules between juxtaposed epithelial (E) and mesenchymal (M) tissues. For example, the instructive signaling potential for tooth development ...
    • The Eponym of Cnogba 

      O Cathasaigh, Tomas (National University of Ireland, 1989)

      Li, Pulin; Lahvic, Jamie L.; Binder, Vera; Pugach, Emily K.; Riley, Elizabeth B.; Tamplin, Owen J.; Panigrahy, Dipak; Bowman, Teresa V.; Barrett, Francesca G.; Heffner, Garrett C.; McKinney-Freeman, Shannon; Schlaeger, Thorsten M.; Daley, George Q.; Zeldin, Darryl C.; Zon, Leonard I. (2015)
      Haematopoietic stem and progenitor cell (HSPC) transplant is a widely used treatment for life-threatening conditions including leukemia; however, the molecular mechanisms regulating HSPC engraftment of the recipient niche ...
    • Epsilon-near-zero behavior from plasmonic Dirac point: Theory and realization using two-dimensional materials 

      Mattheakis, Marios; Valagiannopoulos, Constantinos A.; Kaxiras, Efthimios (American Physical Society, 2016)
      The electromagnetic response of a two-dimensional metal embedded in a periodic array of a dielectric host can give rise to a plasmonic Dirac point that emulates epsilon-near-zero (ENZ) behavior. This theoretical result is ...
    • Epstein – Barr Virus Evasion of Intrinsic and Innate Immune Pathways During the Viral Lytic Cycle 

      Yiu, Stephanie Pei Tung (2023-05-12)
      Epstein-Barr virus (EBV) persistently infects most people worldwide and causes infectious mononucleosis. It is associated with 200,000 cancers per year and a major multiple sclerosis trigger. EBV colonizes the B-cell ...
    • Epstein–Barr virus latent genes 

      Kang, Myung-Soo; Kieff, Elliott (Nature Publishing Group, 2015)
      Latent Epstein–Barr virus (EBV) infection has a substantial role in causing many human disorders. The persistence of these viral genomes in all malignant cells, yet with the expression of limited latent genes, is consistent ...
    • Equal Opportunity Law and the Construction of Internal Labor Markets 

      Dobbin, Frank; Sutton, John R.; Meyer, John W.; Scott, W. Richard (University of Chicago Press, 1993)
      Internal labor markets have been explained with efficiency and control arguments; however, retrospective event-history data from 279 organizations suggest that federal Equal Employment Opportunity (EEO) law was the force ...
    • Equal, Similar, but Different: Convergent Bonobos and Conserved Chimpanzees 

      Hare, Brian; Wrangham, Richard (Harvard University Press, 2017-12-31)
      A critical goal for human evolutionary biology is understanding when and how traits evolved in our ancestral lineage during the 6.5-9.3 million years since our split with the ancestors of chimpanzees and bonobos. Comparisons ...
    • Equality of Resources and Equality of Welfare: A Forced Marriage? 

      Scanlon, Thomas (University of Chicago Press, 1986)
    • Equality, Efficiency, and Market Fundamentals: The Dynamics of International Medical Care Reform. 

      Cutler, David (American Economic Association, 2002)
      Public opinion surveys uniformly show low support for medical-care systems in developed countries. The longstanding conflict between equal access to care and efficient service provision partly explains this dissatisfaction. ...
    • The Equatorial Thermocline Outcropping—A Seasonal Control on the Tropical Pacific Ocean–Atmosphere Instability Strength 

      Galanti, Eli; Tziperman, Eli; Harrison, Matthew; Rosati, Antony; Giering, Ralf; Sirkes, Ziv (American Meteorological Society, 2002)
      One of the major factors determining the strength and extent of ENSO events, is the instability state of the equatorial Pacific coupled ocean-atmosphere system and its seasonal variations. This study analyzes the coupled ...
    • Equi-energy sampler with applications in statistical inference and statistical mechanics 

      Kou, Shingchang; Zhou, Qing; Wong, Wing Hung (Institute of Mathematical Statistics, 2006)
      We introduce a new sampling algorithm, the equi-energy sampler, for efficient statistical sampling and estimation. Complementary to the widely used temperature-domain methods, the equi-energy sampler, utilizing the ...
    • Equilibrating Nanoparticle Monolayers Using Wetting Films 

      Pontoni, Diego; Alvine, Kyle J.; Checco, Antonio; Gang, Oleg; Ocko, Benjamin M.; Pershan, Peter S. (American Physical Society, 2009)
      Monolayers of bimodal gold nanoparticles on silicon are investigated by a combination of microscopy (dry monolayers) and x-ray diffraction (dry and wet monolayers). In the presence of an excess of small particles, the ...
    • Equilibrium configurations from gravitational collapse 

      Joshi, Pankaj S; Malafarina, Daniele; Narayan, Ramesh (IOP Publishing, 2011)
      We develop here a new procedure within Einstein's theory of gravity to generate equilibrium configurations that result as the final state of gravitational collapse from regular initial conditions. As a simplification, we ...
    • Equilibrium Distribution of Mutators in the Single Fitness Peak Model 

      Tannenbaum, Emmanuel; Deeds, Eric J.; Shakhnovich, Eugene I. (American Physical Society, 2003)
      This Letter develops an analytically tractable model for determining the equilibrium distribution of mismatch repair deficient strains in unicellular populations. The approach is based on the single fitness peak model, ...
    • An Equilibrium Model of "Global Imbalances" and Low Interest Rates 

      Caballero, Ricardo J.; Farhi, Emmanuel; Gourinchas, Pierre-Olivier (American Economic Association, 2008)
      Three of the most important recent facts in global macroeconomics — the sustained rise in the US current account deficit, the stubborn decline in long run real rates, and the rise in the share of US assets in global ...
    • Equilibrium rotational stability and figure of Mars

      Most retroviruses require translational recoding of a viral messenger RNA stop codon to maintain a precise ratio of structural (Gag) and enzymatic (Pol) proteins during virus assembly. Pol is expressed exclusively as a ...
    • Equity for Open-Access Journal Publishing 

      Shieber, Stuart M. (Public Library of Science, 2009)
