Electromagnetic absorption of quasi-1D Majorana nanowires [PDF]

open access: yes, 2015
We calculate the electromagnetic absorption cross section of long and narrow nanowires, in the so-called quasi-1D limit. We consider only two transverse bands and compute the dipole absorption cross section taking into account quasiparticle transitions ...

A catalogue of absorption-line systems in QSO spectra

open access: yes, 2003
We present a new catalog of absprption-line systems identified in the quasar spectra. It contains data on 821 QSOs and 8558 absorption systems comprizing 16139 absorption lines with measured redshifts in the QSO spectra.

Detection of OH absorption against PSR B1849+00

open access: yes, 2003
We have searched for OH absorption against seven pulsars using the Arecibo telescope. In both OH mainlines (at 1665 and 1667 MHz), deep and narrow absorption features were detected toward PSR B1849+00. In addition, we have detected several absorption and

Transmission, reflection and localization in a random medium with absorption or gain

open access: yes, 2005
We study reflection and transmission of waves in a random tight-binding system with absorption or gain for weak disorder, using a scattering matrix formalism.

The measurement of ionospheric absorption using extraterrestrial radio waves [PDF]

open access: yes, 1957
Introduction: The discovery by Jansky in 1932 of the presence of radio waves incident upon the earth from outer space has led to several new methods of studying the earth's upper atmosphere.

Galaxy Morphology - Halo Gas Connections

open access: yes, 2005
We studied a sample of 38 intermediate redshift MgII absorption-selected galaxies using (1) Keck/HIRES and VLT/UVES quasar spectra to measure the halo gas kinematics from MgII absorption profiles and (2) HST/WFPC-2 images to study the absorbing galaxy ...

Increased coproporphyrin serum levels in healthy volunteers treated with the cholesterol uptake inhibitor ezetimibe

open access: yesClinical and Translational Science
Ezetimibe undergoes glucuronidation that results in the active metabolite ezetimibe phenoxy‐glucuronide (ezetimibe‐glucuronide). This phase‐II metabolite was shown to interact with the clinically relevant hepatic transporter organic anion transporting ...

The convolution theorem for nonlinear optics

open access: yes, 2007
We have expressed the nonlinear optical absorption of a semiconductor in terms of its linear spectrum. We determined that the two-photon absorption coefficient in a strong DC-electric field of a direct gap semiconductor can be expressed as the product of

Hyperspectral Differentiation of Phytoplankton Taxonomic Groups: A Comparison between Using Remote Sensing Reflectance and Absorption Spectra

open access: yesRemote Sensing, 2015
The emergence of hyperspectral optical satellite sensors for ocean observation provides potential for more detailed information from aquatic ecosystems.

Sensitivity of p-mode absorption on magnetic region properties and kernel functions

open access: yes, 2011
Aims. Magnetohydrodynamic (MHD) sausage tube waves are excited in magnetic flux tubes by p-mode forcing. These tube waves carry energy away from the p-mode cavity which results in a source of absorption.
