Lifetime distributions from tracking individual BC3H1 cells subjected to yessotoxin
(2015)This work shows examples of lifetime distributions for individual BC3H1 cells after start of exposure to the marine toxin yessotoxin (YTX) in an experimental dish. The present tracking of many single cells from time-lapse ... -
Linear motion of multiple superposed viscous fluids
(2019-04-16)In this paper the small-amplitude motion of multiple superposed viscous fluids is studied as a linearized initial-value problem. The analysis results in a closed set of equations for the Laplace transformed amplitudes of ... -
Localized mesosphere-stratosphere-troposphere radar echoes from the E region at 69 degrees N: Properties and physical mechanisms
(2011)We present the first observations, to our knowledge, of a new class of high-latitude mesosphere-stratosphere-troposphere radar echoes from the E region as observed with the Arctic Lidar Observatory for Middle Atmosphere ... -
A logical characterisation of SPARQL federation
(2014)The paper provides a logical characterisation of distributed processing of SPARQL queries. The principal notion analysed is that of a distribution scheme; a pair consisting of an evaluation rule and a distribution function. ... -
Long-range tropospheric transport of uranium and plutonium weapons fallout from Semipalatinsk nuclear test site to Norway
(2013)A combination of state-of-the-art isotopic fingerprinting techniques and atmospheric transport modelling using real-time historical meteorological data has been used to demonstrate direct tropospheric transport of radioactive ... -
Long-Term Measurements of Tropospheric Scintillation at Very Low Elevation Angles - Initial Analysis
(2022-05-11)Four years of scintillation measurements at very low elevation angles at Kjeller, Norway are analyzed and compared with the ITU-R model. One year is at Ka band with an elevation angle of 3°, and three years are of simultaneous ... -
A LoRa Mesh Network Asset Tracking Prototype
(2020)Long Range (LoRa) is a low powered wide area communications technology, which uses radio frequencies in the industrial, scientific and medical (ISM) band to transmit data over long distances. Due to these properties, i.e., ... -
Low-Complexity Adaptive Sonar Imaging
(2016)We have studied the low-complexity adaptive (LCA) beamformer in active sonar imaging. LCA can be viewed as either a simplification of the minimum variance distortionless response (MVDR) beamformer, or as an adaptive extension ... -
Low-energy enhancement of nuclear γ strength and its impact on astrophysical reaction rates
(2014)An unexpected enhancement in the low-energy part of the γ-strength function for light and medium-mass nuclei has been discovered at the Oslo Cyclotron Laboratory. This enhancement could lead to an increase in the neutron-capture ... -
LTE for Military Communication - Business Models and Vulnerabilities
(2017)This document outlines security issues concerning military use of LTE. It illustrates implications of different business models, and outlines vulnerabilities that decision makers should be aware of in order to protect the ... -
Making the Milrem Themis UGV ready for autonomous operations
(2021-04-12)The usage of Unmanned Ground Vehicles (UGVs) in defence application is increasing, and much research effort is put into the field. Also, many defence vehicle producers are developing UGV platforms. However, the autonomy ... -
The malleability of competitive preferences
(2023-04-14)Men are more competitive than women, but we do not know how stable competitive preferences are. We conduct a pre-registered data collection in the Norwegian Armed Forces, a traditionally male environment, using survey ... -
Marine mammals and sonar: dose-response studies, the risk-disturbance hypothesis and the role of exposure context
(2017)Marine mammals may be negatively affected by anthropogenic noise. Behavioural response studies (BRS) aim to establish a relationship between noise exposure conditions (dose) from a potential stressor and associated behavioural ... -
Mass analysis of charged aerosol particles in NLC and PMSE during the ECOMA/MASS campaign
(2009)MASS (Mesospheric Aerosol Sampling Spectrometer) is a multichannel mass spectrometer for charged aerosol particles, which was flown from the Andoya Rocket Range, Norway, through NLC and PMSE on 3 August 2007 and through ... -
Maternal deprivation of Lewis rat pups increases the severity of experimental periodontitis in adulthood
(2015)Background and Objective: Early life adverse events may influence susceptibility/resistance to chronic inflammatory diseases later in life by permanently dysregulating brain-controlled immune-regulatory systems. We ... -
Mathematical modelling of the oxygen uptake kinetics during whole-body endurance exercise and recovery
(2017)In this study, we elucidate four different mathematical models of the kinetics of oxygen uptake during whole-body endurance exercise at different intensities and throughout the subsequent recovery periods. We employ the ... -
Mathematical relations related to the lode parameter for studies of ductility
(2016)During plastic flow, hydrostatic pressure and plastic strain control the size of the yield surface while the Lode angle is responsible for its shape. The von Mises yield condition shows no dependency of the Lode angle ... -
Mathematical simulation of enegy expenditure and recovery during sprint cross-country skiing
(2014)Purpose: A cross-country sprint competition relies on maximal effort durations of 3–4 minutes. Significant anaerobic energy contribution is expected. Anaerobic energy contribution has been estimated in different sports to ... -
Measured and modeled spatial rain rate correlation to improve the prediction method for satellite site diversity
(2015)Rainfall rate varies both temporarily and spatially. Radio systems, where rain attenuation causes outages, may take advantage of this effect to increase the radio link or satellite link availability using diversity techniques. ... -
Measurement of point spread function for characterization of coregistration and resolution: Comparison of two commercial hyperspectral cameras
(2018)For spectral cameras, the spatial resolution and coregistration of bands are important performance characteristics. The paper discusses how these can be quantified in a way that is relevant for the spectroscopic processing ...
