It reports the early results of Task 2.1 on investigating and modeling the trade-off between energy and performance in concurrent data structures and algorithms, which forms the basis for the whole work package 2 (WP2). The work has been ... -
The NOOP experimental Python programming environment
(Journal article; Tidsskriftartikkel; Preprint; Manuskript, 2014)Python is a dynamic language well suited to build a run-time providing adaptive support to distributed applications. Python has dynamic typing where variables are given a type when they are assigned a value. To introduce type safety, interfaces, and a component model in Python NOOP introduces a type language and a way to apply typing to functions (and methods). This type system is described in the ... -

Quantitative assessment of morphology and sub-cellular changes in macrophages and trophoblasts during inflammation
(Journal article; Tidsskriftartikkel; Peer reviewed, 2020-06-12)In pregnancy during an inflammatory condition, macrophages present at the feto-maternal junction release an increased amount of nitric oxide (NO) and pro-inflammatory cytokines such as TNF-α and INF-γ, which can disturb the trophoblast functions and pregnancy outcome. Measurement of the cellular and sub-cellular morphological modifications associated with inflammatory responses are important in order ... -
Analyse av paleozoiske forkastninger og deres relasjon til devon-karbon avsetninger langs Sassenfjorden og Tempelfjorden, Svalbard, basert på multiverktøy land og fjord-datasett.
(Master thesis; Mastergradsoppgave, 2020-09-02)Ledd i Billefjordforkastningssonen kan man finne på begge sidene av Sassenfjorden. Disse leddene er forsøkt knyttet sammen i denne analysen. Batymetriske data fra Sassenfjordens fjordbunn avslører rygger og andre strukturer som har en spennende innvirkning på de seismiske dataene. Hovedfunnene i denne analysen er kategorisert i tre kategorier. Kategori 1 omtaler en obskur sone på seismikken som ... -
Statistical estimation of global surface temperature response to forcing under the assumption of temporal scaling
(Journal article; Tidsskriftartikkel; Peer reviewed, 2020-04-08)Reliable quantification of the global mean surface temperature (GMST) response to radiative forcing is essential for assessing the risk of dangerous anthropogenic climate change. We present the statistical foundations for an observation-based approach using a stochastic linear response model that is consistent with the long-range temporal dependence observed in global temperature variability. We ... -

Protonation-Induced Hyperporphyrin Spectra of meso-Aminophenylcorroles
(Journal article; Tidsskriftartikkel; Peer reviewed, 2020-04-06)UV–vis spectrophotometric titrations have been carried out on <i>meso-</i>tris(<i>o/m/p</i>-aminophenyl)corrole (H<sub>3</sub>[<i>o/m/p</i>-TAPC]) and <i>meso-</i>triphenylcorrole (H<sub>3</sub>[TPC]) in dimethyl sulfoxide with methanesulfonic acid (MSA). Monoprotonation was found to result in hyperporphyrin spectra characterized by new, red-shifted, and intense Q bands. The effect was particularly ... -
Numerical and experimental investigation of absorbing polymer films suitable for boundary photoacoustic imaging
(Master thesis; Mastergradsoppgave, 2020-07-13)One of the main challenges in conventional photoacoustic methods, is that thin biological samples typically have low optical absorption in the visible region. Therefore, it is often necessary to stain or label the sample with a color which provide sufficient absorption for the laser wavelength used in the scanning system. Unfortunately, the labeling often introduce unwanted properties to the biological ... -
Design and Implementation of a Software Defined Ionosonde. A contribution to the development of distributed arrays of small instruments
(Master thesis; Mastergradsoppgave, 2020-06-29)In order to make advances in studies of mesoscale ionospheric phenomena, a new type of ionosonde is needed. This ionosonde should be relatively inexpensive and small form factor. It should also be well suited for operation in a network of transmit and receiver sites that are operated cooperatively in order to measure vertical and oblique paths between multiple transmitters and receivers in the ... -

Does Arctic warming reduce preservation of organic matter in Barents Sea sediments?
(Journal article; Tidsskriftartikkel; Peer reviewed, 2020-08-31)Over the last few decades, the Barents Sea experienced substantial warming, an expansion of relatively warm Atlantic water and a reduction in sea ice cover. This environmental change forces the entire Barents Sea ecosystem to adapt and restructure and therefore changes in pelagic–benthic coupling, organic matter sedimentation and long-term carbon sequestration are expected. Here we combine new and ... -
Predicting liquid loss of frozen and thawed cod from hyperspectral imaging
(Journal article; Tidsskriftartikkel; Peer reviewed, 2020-08-20)As the ability to appraise the quality of every fish in a delivery in a consistent, objective, and rapid manner has numerous advantages for both sellers and buyers, there has been much research into methods to achieve this. One possible proxy for quality assessment is liquid loss, which correlates with undesirable sensory attributes. This study evaluated whether hyperspectral imaging could predict ... -
miRNAs Predicted to Regulate Host Anti-viral Gene Pathways in IPNV-Challenged Atlantic Salmon Fry Are Affected by Viral Load, and Associated With the Major IPN Resistance QTL Genotypes in Late Infection
(Journal article; Tidsskriftartikkel; Peer reviewed, 2020-09-11)Infectious pancreatic necrosis virus (IPNV) infection has been a major problem in salmonid aquaculture. Marker-assisted selection of individuals with resistant genotype at the major IPN quantitative trait locus (IPN-QTL) has significantly reduced mortality in recent years. We have identified host miRNAs that respond to IPNV challenge in salmon fry that were either homozygous resistant (RR) or ... -

Humanoid Robot handling Hand-Signs Recognition
(Master thesis; Mastergradsoppgave, 2020-08-16)Recent advancements in human-robot interaction have led to tremendous improvement for humanoid robots but still lacks social acceptance among people. Though verbal communication is the primary means of human-robot interaction, non-verbal communication that is proven to be an integral part of the human interactions is not widely used in humanoid robots. This thesis aims to achieve human-robot interaction ... -
Towards Improved Support for Conflict-Free Replicated Data Types
(Master thesis; Mastergradsoppgave, 2020-06-30)Conflict-free Replicated Data Types (CRDTs) are distributed data types which ensure Strong Eventual Consistency (SEL), and also has properties such as commutativity and idempotence. There are many variations of CRDTs, and the ones we will study are state-based delta CRDTs. State-based CRDTs is a variation where the CRDT instances synchronize by sending their state to each other. An improvement to ... -
Structural insights into the enhanced carbapenemase efficiency of OXA-655 compared to OXA-10
(Journal article; Tidsskriftartikkel; Peer reviewed, 2020-07-19)Carbapenemases are the main cause of carbapenem resistance in Gram‐negative bacteria. How β‐lactamases with weak carbapenemase activity, such as the OXA‐10‐type class D β‐lactamases, contribute to anti‐bacterial drug resistance is unclear. OXA‐655 is a T26M and V117L OXA‐10 variant, recently identified from hospital wastewater. Despite exhibiting stronger carbapenemase activity towards ertapenem ... -
Quartz textural analysis from an anastomosing shear zone system: Implications for the tectonic evolution of the Ribeira belt, Brazil
(Journal article; Tidsskriftartikkel; Peer reviewed, 2020-07-18)Strain localization and influence of grain-size reduction processes were investigated from field and microstructural observations, and from quartz textural analysis using EBSD, in rocks deformed along an anastomosing network of shear zones in the Ribeira belt in Brazil. Rocks deformed along the Lancinha shear zone (LSZ) display high percentage of recrystallized grains, in which quartz recrystallized ... -
Transformation weakening: Diffusion creep in eclogites as a result of interaction of mineral reactions and deformation
(Journal article; Tidsskriftartikkel; Peer reviewed, 2020-07-09)The deformation of eclogites and the driving forces for their fabric development are an important topic, potentially allowing to determine deformation rates and stresses in subduction zones, where the greatest number of large earthquakes occurs. Here, fabric studies of grain size and shape, texture, and chemical composition from two locations of Variscan and Alpine eclogites are presented. All samples ...
