Homogenization of nonlocal spectral problems
(Journal article; Tidsskriftartikkel; Peer reviewed, 2024-11-11)We consider a spectral problem for convolution-type operators in environments with locally periodic microstructure and study the asymptotic behavior of the bottom of the spectrum. We show that the bottom point of the spectrum converges as the microstructure period tends to zero, and identify the limit in terms of an additive eigenvalue problem for effective Hamilton–Jacobi equation. In the periodic ... -
Seroprevalence and risk factors of brucellosis in pastoralists and their livestock in Central Equatoria State, South Sudan
(Journal article; Tidsskriftartikkel; Peer reviewed, 2024-12-19)Background Brucellosis poses serious public health implications and substantial economic losses in pastoral rural settings in South Sudan. In humans, brucellosis is almost always originating from animals. Current literature provides scant data regarding the seroprevalence of brucellosis in South Sudan. This cross-sectional study investigates the seroprevalence of brucellosis among the pastoral ... -

(Journal article; Tidsskriftartikkel; Peer reviewed, 2024-12-19)Introduction: Tumor-infiltrating lymphocytes are both prognostic and predictive biomarkers for immunotherapy response. However, less is known about the survival benefits of their subpopulations.<p> <p>Methods: Using machine learning models, we assessed the clinical association of the CD8+, PD1+, TCF1+ cel l subset by multiplex immunohistochemistry using tissue microarrays in 553 non-small cell ... -
Proton therapy versus conventional radiotherapy for the treatment of cavernous sinus benign meningioma, a randomized controlled phase III study protocol (COG-PROTON-01)
(Journal article; Tidsskriftartikkel; Peer reviewed, 2024-12-30)Background Proton therapy (PRT) is an innovative radiotherapeutic modality for the treatment of cancer with unique ballistic properties. The depth-dose distribution of a proton beam reduces exposure of healthy tissues to radiations, compared with photon-therapy (XRT). To date, only few indications for proton-therapy, like pediatric cancers, chordomas, or intra-ocular neoplasms, are reimbursed by ... -

Tvangsevakueringen på Sørøya - Overvintring på Sørøya 1944-1945
(Mastergradsoppgave; Master thesis, 2024-11-01)Masteroppgaven «Tvangsvevakueringen på Sørøya - overvintring på Sørøya 1944-1945» tar for seg tvangsevakueringen på Sørøya, med fokus på de mange sivile som overvintret på Sørøya 1944-1945. På Sørøya var det ca. 1000 sivile som hadde unndratt seg den tyske tvangsevakueringen, og levde på flukt fra tyskerne, som stadig landsatte tropper på jakt etter sivile. Problemstillingene som opptar oppgaven, ... -
Meiji restaureringen og nasjonalismen.
(Mastergradsoppgave; Master thesis, 2024-05-15)Oppgaven er et blikk på forholdet mellom nasjonalisme og Meiji-restaureringen som tok sted i Japan ved midten av 1800-tallet. Oppgaven skal se på hva stillingen til nasjonalisme var før, under, og etter restaureringen. Det skal samt forklares hvordan dette vannskillepunktet i japansk historie også var et viktig steg i landet for framveksten av det moderne Japans syn på et internt fellesskap basert ... -
Norske navn på alle karplantefamilier og -ordener
(Journal article; Tidsskriftartikkel; Peer reviewed, 2024)Over time, Norwegian vernacular names have been coined for all vascular plant species, genera, families and orders represented in Norway. Imported, economically important species (used as food, medicine etc.) have also frequently acquired Norwegian names. This still leaves numerous exotic plant families and plant orders without a Norwegian name, albeit sometimes requested e.g. by translators. ... -
En fremmedartet steinalderøks
(Chapter; Bokkapittel, 2024)Hvorfor er en av de veldig få enkle skafthulløksene i Nord-Norge funnet i Rødbergshamna på Lenvikhalvøya? En øksetype som forbindes med jordbruk og rydding av innmark ved slutten av steinalderen i Sør-Norge, men som her må ha befunnet seg i et jakt-, fangst - og fiskelandskap. Tromsø Museum, Universitetsmuseet ved UiT - Norges arktiske universitet, er ett av fem museer i Norge med ansvar for at funn ... -
The Upper Devonian to Lower Carboniferous Billefjorden Group on Bjørnøya, Svalbard, and Its North-Eastern Greenlandic Provenance
(Journal article; Tidsskriftartikkel; Peer reviewed, 2024-12-13)In this contribution, we document changes in detrital zircon ages in the upper Devonian (Famennian) to lower Carboniferous (Mississippian) Billefjorden Group on Bjørnøya, the southernmost island of Svalbard. This alluvial, coal-bearing clastic succession is widely distributed across the archipelago and the Barents Shelf. The sediments were deposited in subsidence-induced lowlands that formed just ... -

(Journal article; Tidsskriftartikkel; Peer reviewed, 2024-03-22)Objectives: This systematic scoping review was conducted to 1) identify and describe labor curves that illustrate cervical dilatation over time; 2) map any evidence for, as well as outcomes used to evaluate the accuracy and effectiveness of the curves; and 3) identify areas in research that require further investigation.<p><p> Methods: A three-step systematic literature search was conducted for ... -
Recognizing Hand-Based Micro Activities Using Wrist-Worn Inertial Sensors: A Zero-Shot Learning Approach
(Chapter; Bokkapittel, 2024-10-23)Zero-shot learning (ZSL) is a machine learning paradigm that enables models to recognize and classify data from classes they have not encountered during training. This approach is particularly advantageous in recognizing activities where labeled data is limited, allowing models to identify new, unseen activities by leveraging semantic knowledge from seen activities. In this paper, we explore the ... -

How well can the fetal heart rate baseline be assessed by intrapartum intermittent auscultation? An interrater reliability and agreement study
(Journal article; Tidsskriftartikkel; Peer reviewed, 2024-08-20)Background: We aimed to examine the inter-reliability and agreement among midwives when assessing the fetal heart rate (FHR) using the handheld Doppler. The primary aim was to measure the reliability and agreement of FHR baseline (baseline) as beats per minute (bpm). The secondary aims were to measure fluctuations from the baseline, defined as increases and decreases, and classifications ... -
“They were sort of in the room with me”: a qualitative study about callers’ experience of video streaming during medical emergency calls
(Journal article; Tidsskriftartikkel; Peer reviewed, 2025-01-08)Background During the recent years, emergency services in several countries have integrated video streaming into medical emergency calls, and research on the topic has gained increased focus. Video streaming during medical emergency calls may change dispatcher’s perspective of the call and can be a helpful tool for supervising bystanders’ first aid. Little research exists, however, about the ... -

Subgroup specific transcriptional regulation of salmonid non-classical MHC class I L lineage genes following viral challenges and interferon stimulations
(Journal article; Tidsskriftartikkel; Peer reviewed, 2024-12-20)Non-classical MHC class I genes which, compared to classical MHC class I, are typically less polymorphic and have more restricted expression patterns are attracting interest because of their potential to regulate immune responses to various pathogens. In salmonids, among the numerous non-classical MHC class I genes identified to date, L lineage genes, including Sasa-LIA and Sasa-LGA1, ... -
Arctic Tectonics and Volcanism: a multi-scale, multi-disciplinary educational approach
(Journal article; Tidsskriftartikkel; Peer reviewed, 2024-12-16)Geologically, the Arctic is one of the least-explored regions of Earth. Obtaining data in the high Arctic is logistically, economically, and environmentally expensive, but the township of Longyearbyen (population of 2617 as of 2024) at 78° N represents a relatively easily accessible gateway to Arctic geology and is home to The University Centre in Svalbard (UNIS). These unique factors provide a ... -
Contrasting two major Arctic coastal polynyas: the role of sea ice in driving diel vertical migrations of zooplankton in the Laptev and Beaufort seas
(Journal article; Tidsskriftartikkel; Peer reviewed, 2024-12-17)The diel vertical migration (DVM) of zooplankton is one of the largest species migrations to occur globally and is a key driver of regional ecosystems and the marine carbon pump. Previously thought to be hampered by the extreme light regime prevailing in the Arctic Ocean, observations have revealed that DVM does occur in ice-covered Arctic waters and suggest the decline in Arctic sea ice may thereby ...
