Observability of Dual Active Galactic Nuclei in Merging Galaxies
(IOP Publishing, 2012)
Supermassive black holes (SMBHs) have been detected in the centers of most nearby massive galaxies. Galaxies today are not only the products of billions of years of galaxy mergers, but also billions of years of SMBH activity ...
A computational investigation of the impact of aberrated Gaussian laser pulses on electron beam properties in laser-wakefield acceleration experiments
(The American Institute of Physics, 2011-05)
Barrier height of Pt--In[sub x]Ga[sub 1 - x]N (0 <= x <= 0.5) nanowire Schottky diodes
(The American Institute of Physics, 2011-05-02)
Countering beam divergence effects with focused segmented scintillators for high DQE megavoltage active matrix imagers
(IOP Publishing, 2012)
The imaging performance of active matrix flat-panel imagers designed for megavoltage imaging (MV AMFPIs) is severely constrained by relatively low x-ray detection efficiency, which leads to a detective quantum efficiency ...
Nanopore‐Based, Rapid Characterization of Individual Amyloid Particles in Solution: Concepts, Challenges, and Prospects
(World Health OrganizationWiley Periodicals, Inc., 2018-11)
Aggregates of misfolded proteins are associated with several devastating neurodegenerative diseases. These so‐called amyloids are therefore explored as biomarkers for the diagnosis of dementia and other disorders, as well ...
Fluorine Plasma Treatments of Polypropylene Films, 1 – Surface Characterization Part 2: cf. ref. 11
(WILEY-VCH Verlag, 2010-02-22)
In this work, an experimental investigation of fluorine gas (F 2 ) plasma treatment of polypropylene (PP) film reveals the evolution of PP fluorination. Surface analysis of fluorinated PP surfaces describes a surface ...
Beam‐induced redox transformation of arsenic during As K‐edge XAS measurements: availability of reducing or oxidizing agents and As speciation
(International Union of CrystallographyWiley Periodicals, Inc., 2018-05-01)
Dynamics of the Overhauser field under nuclear spin diffusion in a quantum dot
(IOP Publishing, 2011)
The coherence of electron spins can be enhanced significantly by preparing the nuclear spin polarizations to generate an Overhauser field with small fluctuations. We propose a theoretical model for calculating the long ...
The Low-mass Stellar Population in L1641: Evidence for Environmental Dependence of the Stellar Initial Mass Function
(IOP Publishing, 2012)
We present results from an optical photometric and spectroscopic survey of the young stellar population in L1641, the low-density star-forming region of the Orion A cloud south of the Orion Nebula Cluster (ONC). Our goal ...
GPU-accelerated voxelwise hepatic perfusion quantification
(IOP Publishing, 2012)
Voxelwise quantification of hepatic perfusion parameters from dynamic contrast enhanced (DCE) imaging greatly contributes to assessment of liver function in response to radiation therapy. However, the efficiency of the ...
