Inverse scattering of dispersive stratified structures
(2012)
We consider the inverse-scattering problem of retrieving the structural parameters of a stratified medium consisting of dispersive materials, given knowledge of the complex reflection coefficient in a finite frequency ...
Electron loss and meteoric dust in the mesosphere
(2012)
The ionosphere is always assumed to contain equal numbers of positive and negative charges in a given volume (quasineutrality). Hence fewer electrons than positive charges are an indication of negative charges other than ...
On the Big Bang Cosmology as a Kinematic Event in Newtonian Cosmology Modified by Dark Energy
(2012)
The concepts dark matter and dark energy are commonly used to explain the universe.
The dark energy can be conceived as a property of vacuum or the ether. However, a
quite different but also common approach is to modify ...
Standoff detection of biological agents using laser induced fluorescence - a comparison of 294 nm and 355 nm excitation wavelengths
(2012)
Standoff detection measuring the fluorescence spectra of seven different biological agents excited by 294 nm as well as 355 nm wavelength laser pulses has been undertaken. The biological warfare agent simulants were released ...
Wideband Interferometry in Synthetic Aperture Sonar
(2013)
Synthetic aperture sonar (SAS) interferometry can provide very high resolution images and topographic maps of the seafloor over large swaths. Processing of interferometric data to retrieve reliable depth estimates of the ...
The perirhinal cortex of rats: An intricate area for microinfusion of anticonvulsants against soman-induced seizures
(2013)
Microinfusion of anticonvulsants into the perirhinal cortex through 1 guide cannula in each hemisphere only invades a small area of this seizure controlling site in rats exposed to soman. The purpose of the present study ...
Serial Ricinine Levels in Serum and Urine after Ricin Intoxication
(2013)
Ricinine is an alkaloid present in the castor bean plant (Ricinus communis) that can be used as a biomarker for ricin poisoning. Serial ricinine levels are reported in the serum and urine of a patient suffering from ...
Pilot Whales Attracted to Killer Whale Sounds: Acoustically-Mediated Interspecific Interactions in Cetaceans
(2012)
In cetaceans’ communities, interactions between individuals of different species are often observed in the wild. Yet, due to methodological and technical challenges very little is known about the mediation of these ...
Using stereo SAR and InSAR by combining the COSMO-SkyMed and the TanDEM-X mission satellites for estimation of absolute height
(2013)
The objective of this work is to estimate absolute height in synthetic aperture radar (SAR) interferograms. Since height in interferograms is relative, we use stereo SAR with several satellites to achieve absolute height ...
Reciprocity and the scattering matrix of waveguide modes
(2013)
The implications of the Lorentz reciprocity theorem for a scatterer connected to waveguides with arbitrary modes, including degenerate, evanescent, and complex modes, are discussed. In general it turns out that a matrix ...
