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 ... -
Enhancing far-field thermal emission with thermal extraction
(2013)The control of thermal radiation is of great current importance for applications such as energy conversions and radiative cooling. Here we show theoretically that the thermal emission of a finite-size blackbody emitter can ... -
Large scale MALDI-TOF MS based taxa identification to identify novel pigment producers in a marine bacterial culture collection
(2013)A challenge in the rational exploitation of microbial culture collections is to avoid superfluous testing of replicas. MALDI-TOF MS has been shown to be an efficient dereplication tool as it can be used to discriminate ... -
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 ... -
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 ... -
Validation of replay-based underwater acoustic communication channel simulation
(2013)This paper discusses validation methods for underwater acoustic communication channel simulators, and validates direct and stochastic replay of underwater acoustic communication channels as implemented in a channel simulator ... -
Estimating temperature and salinity profiles using empiricalorthogonal functions and clusteringon historical measurements
(2013)Oceanographic climatology is normally estimated by dividing the world’s oceans into geographical boxes of fixed shape and size, where each box is represented by a climatological salinity and temperature profile. The ... -
Construction and demonstration of a multispectral tomographic scanning imager (TOSCA)
(2013)This work presents the first experimental demonstrator of an imager based on a tomographic scanning (TOSCA) principle. The device described generates a stream of multispectral images of a scene or target using simple conical ... -
Estimating the capture and loss of cold plasma from ionospheric outflow
(2012)An important source of magnetospheric plasma is cold plasma from the terrestrial ionosphere. Low energy ions travel along the magnetic field lines and enter the magnetospheric lobes where they are convected toward the tail ... -
Bringing the economy back in: The political economy of security sector reform
(2013)The mechanisms underlying the relation between development and security are difficult to define and poorly understood. This has not hindered various donor countries, NGOs, or international organizations from designing and ... -
A simulation of cross-country skiing on varying terrain by using a mathematical power balance model
(2013)The current study simulated cross-country skiing on varying terrain by using a power balance model. By applying the hypothetical inductive deductive method, we compared the simulated position along the track with actual ... -
Methicillin-Resistant Staphylococcus aureus (MRSA) Is Increasing in Norway: A Time Series Analysis of Reported MRSA and Methicillin-Sensitive S. aureus Cases, 1997–2010
(2013)The current study simulated cross-country skiing on varying terrain by using a power balance model. By applying the hypothetical inductive deductive method, we compared the simulated position along the track with actual ... -
A model for the viscous dissipation rate in stably stratified, sheared turbulence
(2013)A model for the turbulence dissipation rate in stably stratified shear turbulence is developed and validated. The functional dependence of the model is derived from first principles and it represents a conceptually new ... -
Legionella and non-Legionella bacteria in a biological treatment plant
(2013)Legionella pneumophila were previously identified in the aeration ponds (up to 1010 CFU/L) of a biological wastewater treatment plant at Borregaard Ind. Ltd., Sarpsborg, Norway, and in air samples (up to 3300 CFU/m3) ... -
Physical Working Principles of Medical Radar
(2013)There has been research interest in using radar for contactless measurements of the human heartbeat for several years. While many systems have been demonstrated, not much attention have been given to the actual physical ... -
Rapid Identification of Bacillus anthracis Spores in Suspicious Powder Samples by Using Matrix-Assisted Laser Desorption Ionization-Time of Flight Mass Spectrometry (MALDI-TOF MS)
(2013)Rapid and reliable identification of Bacillus anthracis spores in suspicious powders is important to mitigate the safety risks and economic burdens associated with such incidents. The aim of this study was to develop and ... -
Pixel scaling in infrared focal plane arrays
(2013)We discuss effects that arise in pixels of IR focal plane arrays (FPAs) when pixel size scales down to approach the wavelength of the incident radiation. To study these effects, we perform first-principles electromagnetic ... -
Responses of male sperm whales (Physeter macrocephalus) to killer whale sounds: implications for anti-predator strategies
(2013)Interactions between individuals of different cetacean species are often observed in the wild. Killer whales (Orcinus orca) can be potential predators of many other cetaceans, and the interception of their vocalizations ... -
Payload charging events in the mesosphere and their impact on Langmuir type electric probes
(2013)Three sounding rockets were launched from Andøya Rocket Range in the ECOMA campaign in December 2010. The aim was to study the evolution of meteoric smoke particles during a major meteor shower. Of the various instruments ... -
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 ...
