Rest‐Frame Ultraviolet to Near‐Infrared Observations of an Interacting Lyman Break Galaxy at z = 4.42
(American Astronomical Society, 2007)
Mammalian Plasma Membrane Ecto-nucleoside Triphosphate Diphosphohydrolase 1, Cd39, Is Not Active Intracellularly. The N-glycosylation State of Cd39 Correlates with Surface Activity and Localization
(American Society for Biochemistry and Molecular Biology, 2001)
Are most low-luminosity active galactic nuclei really obscured?
(Oxford University Press, 2009)
At low Eddington ratios ((m)over dot), two effects make it more difficult to detect certain active galactic nuclei (AGN) given a particular set of selection methods. First, even allowing for fixed accretion physics, at low ...
Constraining the Nature of the Galactic Center X-Ray Source Population
(American Astronomical Society, 2005)
We searched for infrared counterparts to the cluster of X-ray point sources discovered by Chandra in the Galactic center region (GCR). While the sources could be white dwarfs, neutron stars, or black holes accreting from ...
Velocity Structure of the Interstellar Medium as Seen by the Spectral Correlation Function
(American Astronomical Society, 2002)
We use the statistical tool known as the "spectral correlation function" (SCF) to intercompare simulations and observations of the atomic interstellar medium ( ISM). The simulations considered, which mimic three distinct ...
Identification of Ald6p as the target of a class of small-molecule suppressors of FK506 and their use in network dissection
(National Academy of Sciences, 2004)
FK506 inhibits the Ca2+ /calmodulin-dependent protein phosphatase calcineurin, which plays a critical role in yeast subjected to salt stress. A chemical genetic screen for small molecules that suppress growth inhibition ...
Spectra of the X‐Ray Emission Induced in the Interaction between the Solar Wind and the Heliospheric Gas
(American Astronomical Society, 2004)
Spectra of the heliospheric EUV and X-ray emission induced in the charge transfer collisions of the highly charged solar wind ions with the interstellar gas have been calculated. Cascading photon spectra of individual Oq+, ...
Theory and application of Fermi pseudo-potential in one dimension
(AIP Publishing, 2002)
The theory of interaction at one point is developed for the one-dimensional Schrodinger equation. In analog with the three-dimensional case, the resulting interaction is referred to as the Fermi pseudo-potential. The ...
Quantum electrodynamics of accelerated atoms in free space and in cavities
(American Physical Society, 2006)
We consider a gedanken experiment with a beam of atoms in their ground state that are accelerated through a single-mode cavity. We show that taking into account of the "counterrotating" terms in the interaction Hamiltonian ...
Are We Beyond Good and Evil?
(2004)
In this essay, we criticize the tacit radical psychological materialist reduction of mental to brain behavior and the consequent ‘elimination’ of ethical categories from ‘scientific’ discourse. Our argument, following ...
