Method for retrieval of aerosol optical depth from multichannel irradiance measurements
(Journal article; Peer reviewed, 2023)We present, to the best of our knowledge, a new method for retrieval of aerosol optical depth from multichannel irradiance measurements. A radiative transfer model is used to simulate measurements to create the new aerosol ... -
On the Potential for Optical Detection of Microplastics in the Ocean
(Journal article; Peer reviewed, 2023) -
Behaviour of anadromous brown trout (Salmo trutta) in a hydropower regulated freshwater system
(Journal article; Peer reviewed, 2023)Many Norwegian rivers and lakes are regulated for hydropower, which afects freshwater ecosystems and anadromous fish species, such as sea trout (Salmo trutta). Lakes are an important feature of many anadromous river systems. ... -
Height Determination of a Blue Discharge Observed by ASIM/MMIA on the International Space Station
(Journal article; Peer reviewed, 2023)We analyze simultaneous photometric observations of thundercloud discharges from the Modular Multispectral Imaging Array of the Atmosphere-Space Interactions Monitor (ASIM) on board the International Space Station with ... -
Multi-Task Optimization in Reliability Redundancy Allocation Problem: A Multifactorial Evolutionary-Based Approach
(Journal article; Peer reviewed, 2024)Evolutionary multi-task optimization attempts to solve multiple optimization problems simultaneously by modeling the solution structures of two or more problems within a single encoding. In this paper, we report a novel ... -
Observational and Model Impact of Tonga Volcano Eruption on Schumann Resonance
(Journal article; Peer reviewed, 2023)Tonga volcano eruption on 15 January 2022 was accompanied by an unprecedentedly high lightning activity in the volcano plume which significantly exceeded the lightning activity level of the whole globe. We compare model ... -
Improved multivariable algorithms for estimating oceanic particulate organic carbon concentration from optical backscattering and chlorophyll-a measurements
(Journal article; Peer reviewed, 2024-01-08)The capability to estimate the oceanic particulate organic carbon concentration (POC) from optical measurements is crucial for assessing the dynamics of this carbon reservoir and the capacity of the biological pump to ... -
Limited Link of Common Blood Parameters with Tinnitus
(Journal article; Peer reviewed, 2023)Background: Tinnitus severity is generally assessed by psychometric and audiological instruments. However, no objective measure exists to evaluate the subjective discomfort and suffering caused by this hearing phenomenon. ... -
Nitrite accumulation and anammox bacterial niche partitioning in Arctic Mid-Ocean Ridge sediments
(Journal article; Peer reviewed, 2023)By consuming ammonium and nitrite, anammox bacteria form an important functional guild in nitrogen cycling in many environments, including marine sediments. However, their distribution and impact on the important substrate ... -
Quantifying prior model complexity for subsurface reservoir models
(Journal article; Peer reviewed, 2023)In Bayesian approaches to history matching for subsurface inference, the prior model specifies the uncertain model parameters and the joint probability of those parameters before incorporating production-related data. A ... -
Hardware architecture of Dillon's APN permutation for different primitive polynomials
(Journal article; Peer reviewed, 2023)Cryptographically strong functions used as S-boxes in block cyphers are fundamental for the cypher’s security. Their representation as lookup tables is possible for functions of small dimension. For larger dimensions, this ... -
Application of CRISPR-based gene editing tools in Atlantic salmon
(Doctoral thesis, 2024-05-15)Atlantisk laks er den viktigaste arten i norsk havbruksnæring. Næringa i Noreg er i dag ramma av fleire berekraftsufordringar, til dømes genetisk innblanding av rømt laks, og spreiing av smittsame sjukdommar. Dette påverkar ... -
Vector meson photoproduction in UPCs with FoCal
(Journal article; Peer reviewed, 2023)We discuss the physics prospects of photon-induced measurements using the high-granularity FoCal detector to be installed at the ALICE experiment, covering the pseudorapidity interval 3.4 ≤ η ≤ 5.8. This new detector, ... -
Realistic mask generation for matter-wave lithography via machine learning
(Journal article; Peer reviewed, 2023)Fast production of large-area patterns is crucial for the established semiconductor industry and enables industrial-scale production of next-generation quantum devices. Metastable atom lithography with binary holography ... -
Phonon-Mediated Quasiparticle Lifetime Renormalizations in Few-Layer Hexagonal Boron Nitride
(Journal article; Peer reviewed, 2023)Understanding the collective behavior of the quasiparticles in solid-state systems underpins the field of non-volatile electronics, including the opportunity to control many-body effects for well-desired physical phenomena ... -
Neutral helium atom microscopy
(Journal article; Peer reviewed, 2023)Neutral helium atom microscopy, also referred to as scanning helium microscopy and commonly abbreviated SHeM or NAM (neutral atom microscopy), is a novel imaging technique that uses a beam of neutral helium atoms as an ... -
Operational modelling to assess advective harmful algal bloom development and its potential to impact aquaculture
(Journal article; Peer reviewed, 2023)A particle tracking model is described and used to explore the role of advection as the source of harmful algal blooms that impact the Shetland Islands, where much of Scotland's aquaculture is located. The movement of ... -
Ten priority questions for increasing the consistency and success in hatchery production of the European flat oyster for habitat restoration
(Journal article; Peer reviewed, 2023)The European flat oyster, Ostrea edulis, once formed extensive reef habitats throughout European seas and estuaries. These reefs are now largely functionally extinct, yet interest and support for their restoration is rapidly ... -
