Wireless power transfer in the presence of metallic plates: Experimental results
(2013)We demonstrate efficient wireless power transfer between two high Q resonators, especially in a complex electromagnetic environment. In the close proximity of metallic plates, the transfer efficiency stays roughly the same ... -
Changes in fibrinogen availability and utilization in an animal model of traumatic coagulopathy
(2013)Background Impaired haemostasis following shock and tissue trauma is frequently detected in the trauma setting. These changes occur early, and are associated with increased mortality. The mechanism behind trauma-induced ... -
Isocyanate-Free and Dual Curing of Smokeless Composite Rocket Propellants
(2013)Traditional composite rocket propellants are cured by treatment of hydroxyl-terminated prepolymers with polyfunctional aliphatic isocyanates. For development of smokeless composite propellants containing nitramines and/or ... -
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 ... -
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 ... -
Effects of a 7-days military training exercise on inflammatory biomarkers, serum hepcidin, and iron status
(2013)Background Hepcidin, a peptide that is released into the blood in response to inflammation, prevents cellular iron export and results in declines in iron status. Elevated serum and urinary levels of hepcidin have been ... -
A Graphical User Interface for Multivariable Analysis of Silicon Solar Cells Using Scripted PC1D Simulations
(2013)PC1D is an open source computer program for simulation of crystalline semiconductor devices, and is the most commonly used simulation software in the solar cell community today. In this work we present a modified version ... -
EFFECT OF COULOMB COLLISIONS ON THE GRAVITATIONAL SETTLING OF LOW AND HIGH FIRST IONIZATION POTENTIAL ELEMENTS
(2013)We model the effect of gravitational settling in the upper chromosphere on O, Fe, Si, and Ne, studying whether Coulomb collisions between ionized low First Ionization Potential (FIP) elements and protons is sufficient to ... -
Ultrawideband underwater acoustic communication channels
(2013)Traditional channel models for communications research are designed for narrowband systems. Underwater acoustic communication systems use a bandwidth that is not small compared with the center frequency of the signal and ... -
Effects of Infliximab and Hydrocortisone on In Vitro Cytokine Responses after Stimulation with Lipopolysaccharide
(2013)Background: Both glucocorticosteroids and biologic drugs such as the tumor necrosis factor (TNF)-α antagonist infliximab are used often in the treatment of rheumatoid arthritis or inflammatory bowel disease. In severe ... -
Information capacity as a figure of merit for spectral imagers: the trade-off between resolution and coregistration
(2013)The performance of spectral imagers is customarily described by several characteristics including resolution, noise, and coregistration. These must be traded off against each other in a practical imager design. This paper ... -
An ATR architecture for algorithm development and testing
(2013)A research platform with four cameras in the infrared and visible spectral domains is under development at the Norwegian Defence Research Establishment (FFI). The platform will be mounted on a high-speed jet aircraft and ... -
Intracavity molecular spectroscopy in the mid-IR using ultra-broadband optical parametric oscillator
(2013)We have performed intracavity molecular spectroscopy of water vapor, isotopic carbon dioxide, methane, acetylene, carbon monoxide, formaldehyde and other gases using broadband mid-IR sync-pumped OPO sources (PPLN-based OPO ... -
High-pulse-energy, linear optical parametric oscillator with narrow and symmetrical far field
(2013)A new method to obtain a narrow and symmetrical far field from a high-pulse-energy optical parametric oscillator (OPO) with a linear resonator has been tested. The OPO employs two identical nonlinear crystals that are cut ... -
Improved estimation of oceanographic climatology using empirical orthogonal functions and clustering
(2013)Vertical profiles of temperature, salinity, and sound speed velocity are used in numerous applications where accurate vertical profiles are crucial. Conventional climatological representations of vertical oceanographic ... -
Three-dimensional multiple-source focalization in an uncertain ocean environment
(2013)This letter develops a Bayesian focalization approach for three-dimensional localization of an unknown number of sources in shallow water with uncertain environmental properties. The algorithm minimizes the Bayesian ... -
Propagation and scattering effects in underwater acoustic communication channels
(2013)Systematic measurements were performed to characterize shallow-water acoustic propagation channels for applications in the field of underwater communications. The survey was conducted in northern Europe and covers the ...
