Variability of Gaseous Attenuation at Very Low Elevation Angle Slant Paths; Measurements and Modelling
(2020-07-08)
Gaseous attenuation variability for a 3.2° elevation angle satellite link operating at 20 GHz in the Norwegian Arctic is analyzed and compared with different models. At a very low elevation link like this one, gaseous ...
Energy deficit increases hepcidin and exacerbates declines in dietary iron absorption following strenuous physical activity: a randomized-controlled cross-over trial
(2020-11-12)
Background
Strenuous physical activity promotes inflammation and depletes muscle glycogen, which may increase the iron regulatory hormone hepcidin. Hepcidin reduces dietary iron absorption and may contribute to declines ...
Pathologic Blood Samples Tolerate Exposure to Vibration and High Turbulence in Simulated Drone Flights, but Plasma Samples Should be Centrifuged after Flight
(2021-01-30)
Objective. Most of the previous studies of drone transport of blood samples examined normal blood samples transported under tranquil air conditions. We studied the effects of 1- and 2-hour drone flights using random vibration ...
Evaluation of Two Path Following Controllers for an Ackermann Off-road Vehicle in Winter and Summer Conditions
(2021-04-02)
Off-road driving can be a challenging task with rapid changes in the driving conditions, terrain and vehicle behavior. For off-road autonomous vehicles, it is important to be robust to these changes, and parts of this ...
Data-Driven Autocalibration for Swath Sonars
(2020-12-20)
Sidelobes in swath sonar water column imagery can obscure targets of interest and create erroneous bottom detections. Differences between ideal and actual element responses limit the achievable sidelobe level for practical ...
The use of Atlantic hagfish (Myxine glutinosa) as a bioindicator species for studies on effects of dumped chemical warfare agents in the Skagerrak. 2. Biochemical biomarkers
(2020)
The sea bottom of the Skagerrak Strait (North Sea) contains munitions loaded with chemical warfare agents (CWA), mostly stored in shipwrecks scuttled intentionally after the end of the World War II. The munition shells ...
The use of Atlantic hagfish (Myxine glutinosa) as a bioindicator for studies on effect of dumped chemical warfare agents in Skagerrak. 1: Liver histopathology.
(2020)
Within the framework of the international project DAIMON (Decision Aid for Marine Munitions), the impact of dumped chemical munitions on fish health was investigated. The Skagerrak Straight (North Sea, at 600 m depth) ...
Investigating robustness of adversarial camouflage (AC) for naval vessels
(2020-09-20)
The use of camouflage is widespread in the biological domain, and has also been used extensively by armed
forces around the world in order to make visual detection and classification of objects of military interest ...
Training of Neural Network Target Detectors Mentored by SO-CFAR
(2020)
A desirable objective in radar detection theory is the ability to detect and recognize targets in intricate scenarios such as in the presence of clutter or multiple closely spaced targets. Herein we propose the use of ...
Toxic effects of gunshot fumes from different ammunitions for small arms on lung cells exposed at the air liquid interface
(2021-01-14)
Concerns have been raised as to whether gunshot fumes induce prolonged reduced lung capacity or even cancer due to inhalation. Gunshot fumes from three different types of ammunition calibre 5.56 mm × 45 NATO were investigated. ...
