The Effect of FIR Emission from SDSS Galaxies on the SFD Galactic Extinction Map
(Oxford University Press (OUP), 2007)We compare the most successful and widely used map of Galactic dust extinction, provided by Schlegel, Finkbeiner & Davis (1998; hereafter SFD), to the galaxy number counts in the Sloan Digital Sky Survey (SDSS) ... -
The effect of first high school science teacher's gender and gender matching on students' science identity in college
(Wiley, 2019-11-12)To encourage the formation of science identity among girls, many scholars and practitioners have suggested to assign samegender science teachers to students so that the teachers can serve as gender role models. However, ... -
The Effect of Growth-Mimicking Continuous Strain on the Early Stages of Skeletal Development in Micromass Culture
(Public Library of Science, 2015)Embryonic skeletogenesis involves proliferation, condensation and subsequent chondrogenic differentiation of mesenchymal precursor cells, and the strains and stresses inherent to these processes have been hypothesized to ... -
Effect of High-Temperature Aging on the Thermal Conductivity of Nanocrystalline Tetragonal Yttria-stabilized Zirconia
(Elsevier, 2012)The thermal conductivity of yttria-stabilized zirconia (YSZ) thermal barrier coatings increases with high-temperature aging. This common observation has been attributed to the densification of the coatings as porosity ... -
Effect of hydrogen-switchable mirrors on the Casimir force
(National Academy of Sciences, 2004)We present systematic measurements of the Casimir force between a gold-coated plate and a sphere coated with a hydrogen-switchable mirror. Hydrogen-switchable mirrors are shiny metals that can become transparent upon ... -
Effect of interactions and disorder on the relaxation of two-level systems in amorphous solids
(American Physical Society, 2017)At low temperatures the dynamical degrees of freedom in amorphous solids are tunneling two-level systems (TLSs). Concentrating on these degrees of freedom, and taking into account disorder and TLS-TLS interactions, we ... -
Effect of intravenous anesthetic propofol on synaptic vesicle exocytosis at the frog neuromuscular junction
(Nature Publishing Group, 2011)Aim: To investigate the presynaptic effects of propofol, a short-acting intravenous anesthetic, in the frog neuromuscular junction. Methods: Frog cutaneous pectoris nerve muscle preparations were prepared. A fluorescent ... -
The Effect of Line-of-Sight Temperature Variation and Noise on Dust Continuum Observations
(American Astronomical Society, 2009)We investigate the effect of line-of-sight temperature variations and noise on two commonly used methods to determine dust properties from dust-continuum observations of dense cores. One method employs a direct fit to a ... -
Effect of Magnesium Ions on Oriented Growth of Calcite on Carboxylic Acid Functionalized Self-Assembled Monolayer
(American Chemical Society (ACS), 2003)The combined effect of templating and solution additives on calcite crystallization was studied. Self-assembled monolayers of mercaptoundecanoic acid supported on silver, as templates, induced the uniform, oriented nucleation ... -
Effect of Marginal Tax Rates on Taxable Income: A Panel Study of the 1986 Tax Reform Act
(University of Chicago Press, 1995)This paper uses a Treasury Department panel of more than 4,000 taxpayers to estimate the sensitivity of taxable income to changes in tax rates based on a comparison of the tax returns of the same individual taxpayers before ... -
The Effect of Milankovitch Variations in Insolation on Equatorial Seasonality
(American Meteorological Society, 2010)Although the sun crosses the equator 2 times per year at the equinoxes, at times in the past the equatorial insolation has had only one maximum and one minimum throughout the seasonal cycle because of Milankovitch orbital ... -
The Effect of Mindfulness on Heart Rate Control
(Springer Verlag, 2009)An experiment was conducted to test the hypothesis that mindful attention to change regarding heart rate (HR) would result in greater control over HR. Experimental groups monitored the changing or stable nature of HR, ... -
Effect of Molecular Structure of Quinones and Carbon Electrode Surfaces on the Interfacial Electron Transfer Process
(American Chemical Society (ACS), 2020-01-28)Quinones can undergo thermodynamically reversible proton-coupled electron transfer reactions and are being applied as electroactive compounds in aqueous organic batteries. However, the electrochemical reversibility of these ... -
The Effect of Noise on the Dust Temperature-Spectral Index Correlation
(American Astronomical Society, 2009)We investigate how uncertainties in flux measurements affect the results from modified blackbody spectral energy distribution (SED) fits. We show that an inverse correlation between the dust temperature T and spectral index ... -
Effect of Non-Hydrostatic Stress on Kinetics and Interfacial Roughness during Solid Phase Epitaxial Growth in Si
(Materials Research Society, 1997)We report preliminary <i>in-situ</i> time-resolved measurements of the effect of uniaxial stress on solid phase epitaxial growth in pure Si (001) for the case of stress applied parallel to the amorphous-crystal interface. ... -
Effect of Nonhydrostatic Stress on Crystal Growth Kinetics
(Materials Research Society, 1991)The effect of nonhydrostatic stresses on the solid phase epitaxial growth rate of crystalline Si(100) into self-implanted amorphous surface layers has been measured. Uniaxial stresses of up to 6 kbar (0.6 GPa) were attained ... -
The effect of one additional driver mutation on tumor progression
(Blackwell Publishing Ltd, 2013)Tumor growth is caused by the acquisition of driver mutations, which enhance the net reproductive rate of cells. Driver mutations may increase cell division, reduce cell death, or allow cells to overcome density-limiting ... -
The Effect of Orbital Configuration on the Possible Climates and Habitability of Kepler-62f
(Mary Ann Liebert, Inc., 2016)Abstract As lower-mass stars often host multiple rocky planets, gravitational interactions among planets can have significant effects on climate and habitability over long timescales. Here we explore a specific case, ... -
Effect of Population III multiplicity on dark star formation
(Oxford University Press, 2012)We numerically study the mutual interaction between dark matter (DM) and Population III (Pop III) stellar systems in order to explore the possibility of Pop III dark stars within this physical scenario. We perform a ...
