To Learn or not to Learn: On the Importance of Mode Switching in Educational Wargames
(2022-09-19)
Conventional wisdom holds that educational wargames come with certain challenges – factors that can potentially hinder, rather than increase, learning – and that these must be mitigated. In this article, we argue that ...
Glioblastoma microenvironment contains multiple hormonal and non-hormonal growth-stimulating factors
(2022-06-04)
Background
The growth of malignant tumors is influenced by their microenvironment. Glioblastoma, an aggressive primary brain tumor, may have cysts containing fluid that represents the tumor microenvironment. The aim of ...
Practical Jamming of a Commercial 5G Radio System at 3.6 GHz
(2022-09-22)
Fifth-generation (5G) mobile technology has attracted interest from armed forces worldwide due to its many new possibilities for communication. Military operations may face threats in the electromagnetic spectrum, such as ...
Collision Avoidance for Underactuated Surface Vehicles in the Presence of Ocean Currents
(2022-11-29)
This paper considers the problem of collision avoidance for surface vehicles moving under the influence of ocean currents. The vehicles we consider have underactuated dynamics, where the vehicle cannot directly control its ...
Spawning Atlantic cod (Gadus morhua L.) exposed to noise from seismic airguns do not abandon their spawning site
(2022-11-15)
Seismic airgun surveys may disturb and displace fish at large ranges. If such displacement causes fish to abandon spawning grounds, reproductive success could be impacted. To investigate whether airgun sound causes cod ...
Wargaming for the Purpose of Knowledge Development: Lessons Learned from Studying Allied Courses Of Action
(2022-09-19)
We present a series of four wargames intended to improve our ability to analyze the alliance aspect of Norwegian military operations. We discuss the objectives, the set-up, and the lessons learned. The wargames proved to ...
Freezing Unicast Paths in Sensor Swarms
(2022-09-22)
Drone swarms have great potential to convey sensor information. However, a swarm may have a very high degree of topology dynamics. This impedes the sensor data distribution from the sensor node to consumers which are ...
Realising benefits in public IT projects: A multiple case study
(2022-12-13)
Information Technology (IT) investments in the public sector are large, and it is essential that they lead to benefits for the organisations themselves and wider society. While there is evidence suggesting a positive ...
Effect of the Series Resistance on the Current Response of a HgCdTe Avalanche Photodiode Under High-intensity Nanosecond Irradiation
(2022-05-10)
We investigate the nonlinear signal current response of a Hg0.72Cd0.28Te avalanche photodiode (APD) irradiated by high-intensity, finite-duration laser pulses. At high irradiation levels and/or high gains, carrier-induced ...
Pro-inflammatory cytokines in cystic glioblastoma: A quantitative study with a comparison with bacterial brain abscesses. With an MRI investigation of displacement and destruction of the brain tissue surrounding a glioblastoma
(2022-07-29)
Cystic glioblastomas are aggressive primary brain tumors that may both destroy and displace the surrounding brain tissue as they grow. The mechanisms underlying these tumors’ destructive effect could include exposure of ...
