High-energy bow tie multi-pass cells for nonlinear spectralbroadening applications
(2022-01-24)
Multi-pass cells (MPCs) have emerged as very attractive tools for spectral broadening and
post-compression applications. We discuss pulse energy limitations of standard MPCs considering
basic geometrical scaling principles ...
Den nye russiske hærreserven – Russlands mobilisering av reservister innen rammen av BARS høsten 2021
(2022-04-19)
Høsten 2021 startet Russland mobilisering av reservister over store deler av landet til en stående hærreserve.
Reservistene som tas opp i hærreserven vil få lønn fra forsvarsministeriet og bli innkalt til månedlige øvelser. ...
A global metagenomic map of urban microbiomes and antimicrobial resistance
(2021-06-24)
We present a global atlas of 4,728 metagenomic samples from mass-transit systems in 60 cities over 3 years, representing the first systematic, worldwide catalog of the urban microbial ecosystem. This atlas provides an ...
Sivil støtte til Forsvaret – en funksjonsbasert tilnærming for modellering av totalforsvarsevne
(2022-05-18)
Formålet med dette arbeidet har vært å utvikle nye metoder for analyse av totalforsvarsevnen som skal understøtte den nasjonale og allierte forsvarsinnsatsen. Basert på systemtenkning for komplekse systemer, har et ...
Unimolecular Decomposition Reactions of Picric Acid and its Methylated Derivatives — A DFT Study
(2022-04-26)
To handle energetic materials safely, it is important to have knowledge about their sensitivity. Density functional theory (DFT) has proven a valuable tool in the study of energetic materials, and in the current work, DFT ...
Quantification of aerosol dispersal from suspected aerosol-generating procedures
(2021-12-06)
Background Oxygen-delivering modalities like humidified high-flow nasal cannula (HFNC) and noninvasive positive-pressure ventilation (NIV) are suspected of generating aerosols that may contribute to transmission of disease ...
Behavioral responses to predatory sounds predict sensitivity of cetaceans to anthropogenic noise within a soundscape of fear
(2022-03-21)
As human activities impact virtually every animal habitat on the planet, identifying species at-risk from disturbance is a priority. Cetaceans are an example taxon where responsiveness to anthropogenic noise can be severe ...
Numerical study of premixed gas explosion in a 1-m channel partly filled with 18650 cell-like cylinders with experiments
(2022-03-22)
Abused and defective Li-ion cells can cause a catastrophic failure of a Li-ion battery (LIB), leading to severe fires and explosions. In recent years, several numerical and experimental studies have been conducted on the ...
A weakening transatlantic relationship? Redefining the EU-US security and defence cooperation
(2022-05-18)
The aim of this article is to discuss how a weakening transatlantic relationship influences European defence cooperation and integration. It also asks how these observed patterns of weakening EU–US relations can be explained ...
Security for Autonomous and Unmanned Devices: Cryptography and its Limits
(2022-02-07)
We survey existing literature on protecting resource constrained autonomous and unmanned devices. The goal is to secure data both during transmission and at rest, also when facing highly skilled and motivated adversaries. ...
