Detection of a Far-Infrared Bow-Shock Nebula Around R Hya: the First MIRIAD Results
(American Astronomical Society, 2006)
We present the first results of the MIRIAD (MIPS InfraRed Imaging of AGB Dust shells) project using the Spitzer Space Telescope. The primary aim of the project is to probe the material distribution in the extended
circumstellar ...
Applying the Polarization Memory Effect in Polarization-gated Subsurface Imaging
(The Optical Society of America, 2006-05)
Polarization memory is a well established phenomenon occurring when circularly polarized light propagates in turbid media of larger particles. Recent studies have demonstrated that the circularly crosspolarized imaging can ...
Expression of Target Optical Properties in Subsurface Polarization-gated Imaging
(The Optical Society of America, 2005-05)
We examined the expression of target optical properties in subsurface polarization imaging under linearly and circularly polarized illumination. Reflecting, scattering, and absorption targets were imaged in tissue mimic ...
Transillumination Optical Tomography of Tissue-Engineered Blood Vessels: A Monte Carlo Simulation
(The Optical Society of America, 2005-07)
A Monte Carlo technique has been developed to simulate the transillumination laser computed tomography of tissue-engineered blood vessels. The blood vessel was modeled as a single cylinder layer mounted on a tubular mandrel. ...
What's the best treatment for CIN 2 or 3?
(Family Physicians Inquiries Network, 2007)
Excision or ablation of the transformation zone are equally effective for treating an initial diagnosis of cervical intraepithelial neoplasia (CIN) grades 2 or 3 in women with a satisfactory colposcopy and no suggestion ...
Lowpass Filtering of Rate-Distortion Functions for Quality Smoothing in Real-Time Video Communication
(IEEE, 2005)
In variable-bit-rate (VBR) video coding, the video is pre-processed to collect sequence-level statistics, which are used
for global bit allocation in the actual encoding stage to obtain a smoothed video presentation ...
(Mis-) Measuring the Relative Pay of Public School Teachers
(Education Finance and Policy, 2006)
Statistics on the relative pay of public school teachers are routinely cited by plaintiffs in school finance (“adequacy”) lawsuits. However, comparisons of pay and
benefits for public school teachers to those of professional ...
A Firework of H2 Knots in the planetary nebula NGC 7293 (The Helix Nebula)
(American Astronomical Society, 2009)
We present a deep and wide field-of-view (4 × 7 ) image of the planetary nebula (PN) NGC 7293 (the Helix Nebula) in the 2.12 μm H2 v = 1 → 0 S(1) line. The excellent seeing (0. 4) at the Subaru Telescope, allows
the ...
Using stochastic models calibrated from nanosecond nonequilibrium simulations to approximate mesoscale information
(American Institute of Physics, 2009)
We demonstrate how the surrogate process approximation (SPA) method can be used to compute both the potential of mean force along a reaction coordinate and the associated diffusion coefficient using a relatively small ...
X-Ray and Radio Interactions in the Cores of Cooling Flow Clusters
(American Astronomical Society, 2000)
We present high-resolution ROSAT X-ray and radio observations of three cooling Ñow clusters containing steep-spectrum radio sources at their cores. All three systems exhibit strong signs of interaction
between the radio ...
On the Carriers of the 21 Micron Emission Feature in Post-Asymptotic Giant Branch Stars
(arXiv, 2009)
The mysterious 21micron emission feature seen in sixteen C-rich proto-planetary nebulae (PPNe) remains unidentified since its discovery in 1989. Over a dozen of materials are suggested as the carrier candidates. In this ...
Feels like home
(MU Alumni Association, University of Missouri, 2006)
In this special section, rediscover Columbia - aka Collegetown USA. Remember how it once was, check out Homecoming details, and get the latest on Tiger football.
Ice chemistry in embedded young stellar objects in the Large Magellanic Cloud
(American Astronomical Society, 2009)
We present spectroscopic observations of a sample of 15 embedded young stellar objects (YSOs) in the Large Magellanic Cloud (LMC). These observations were obtained with the Spitzer Infrared Spectrograph (IRS) as part
of ...
Characterization of Corning EPMA Standard Glasses 95IRV, 95IRW, and 95IRX
(Journal of Research of the National Institute of Standards and Technology, 2002)
The preparation, synthesis, and characterization of Corning trace-element glasses 95IRV, 95IRW, and 95IRX by bulk
chemical and electron microprobe techniques is discussed. Working values for the doped elements in the ...
Comparative study of normal and branched alkane monolayer films adsorbed on a solid surface. II. Dynamics
(American Institute of Physics, 2007)
The dynamics of monolayer films of the n-alkane tetracosane (n-C24H52) and the branched alkane squalane (C30H62) adsorbed on graphite have been studied by quasielastic and inelastic neutron scattering and molecular dynamics ...
Optical Constants of Silicon Carbide for Astrophysical Applications. II. Extending Optical Functions from Infrared to Ultraviolet Using Single-Crystal Absorption Spectra
(American Astronomical Society, 2009)
Laboratory measurements of unpolarized and polarized absorption spectra of various samples and crystal structures of silicon carbide (SiC) are presented from 1200-35000 cm−1 (λ ∼ 8-0.28 μm) and used to improve the
accuracy ...
The Origins Billions Star Survey: Galactic Explorer
(The Astronomical Society of the Pacific, 2006)
The Origins Billions Star Survey is a mission concept addressing the astrophysics of extrasolar planets, Galactic structure, the Galactic halo and tidal streams, the Local Group and local supercluster of galaxies, dark ...
The Calibration of Mid-Infrared Star Formation Rate Indicators
(American Astronomical Society, 2007)
With the goal of investigating the degree to which the MIR emission traces the SFR, we analyze Spitzer 8 and 24 m data of star- forming regions in a sample of 33 nearby galaxies with available HST NICMOS images in the Pa ...
