Multilayer phosphorene quantum dots in an electric field: Energy levels and optical absorption
(Journal article; Peer reviewed, 2018)Triangular and hexagonal multilayer phosphorene quantum dots with armchair and zigzag terminations are investigated with the orthogonal tight-binding model. The effect of increasing the number of layers is revealed. The ... -
Multilevel CC2 and CCSD in Reduced Orbital Spaces: Electronic Excitations in Large Molecular Systems
(Peer reviewed; Journal article, 2021)We present efficient implementations of the multilevel CC2 (MLCC2) and multilevel CCSD (MLCCSD) models. As the system size increases, MLCC2 and MLCCSD exhibit the scaling of the lower-level coupled cluster model. To treat ... -
Multilevel CC2 and CCSD Methods with Correlated Natural Transition Orbital
(Peer reviewed; Journal article, 2019)In the multilevel coupled cluster approach, an active orbital space is treated at a higher level of coupled cluster theory than the remaining inactive orbitals. We introduce the multilevel CC2 method where CC2 is used for ... -
Multilevel coupled cluster methods for large molecular systems
(Doctoral theses at NTNU;2020:240, Doctoral thesis, 2020)The coupled cluster hierarchy of models can be used to accurately describe electronic excitations in molecular systems. However, the standard coupled cluster models are expensive and their cost severely limits the size of ... -
Multilevel coupled cluster theory: Development, implementation and application of multilevel coupled cluster theory for core and valence excited states
(Doctoral thesis at NTNU;2016:267, Doctoral thesis, 2016)This thesis consist of seven papers and an introduction describing the ongoing development and applications of multilevel coupled cluster theory. Coupled cluster theory is one of the most accurate, but also one of the ... -
Multilevel Screening of Ionic Liquid Absorbents for Simultaneous Removal of CO2 and H2S from Natural Gas
(Peer reviewed; Journal article, 2020)For the selection of practically attractive ionic liquids (ILs) as absorbents for simultaneous CO2 and H2S removal from natural gas (NG), a multilevel screening method combining Henry′s law constant (H) and vapor–liquid ... -
Multilocus Sequence Typing of close Neighbours to Bacillus anthracis isolated from Soil Samples
(Master thesis, 2014)The Bacillus cereus group comprises of B. anthracis, B. cereus, B. thuringiensis, B. mycoides, B. pseudomycoides, B. weihenstephanensis and B. cytotoxicus. B. anthracis is the causative agent of anthrax, whilst B. cereus ... -
Multilocus sequence typing of Clostridium botulinum
(Master thesis, 2011)The construction of the genotyping method Multilocus Sequence Typing (MLST) for the bacteria Clostridium botulinum -
Multiomics analysis of rheumatoid arthritis yields sequence variants that have large effects on risk of the seropositive subset
(Peer reviewed; Journal article, 2022)Objectives To find causal genes for rheumatoid arthritis (RA) and its seropositive (RF and/or ACPA positive) and seronegative subsets. Methods We performed a genome-wide association study (GWAS) of 31 313 RA cases (68% ... -
Multiphysical modeling of a next generation PEM electrolyser
(Master thesis, 2023)Anvendelse av hydrogen som energibærer er en viktig teknologi for å møte verdens økende energibehov på en måte frigjort fra karbon. Elektrolyse av vann er en bærekraftig metode å produsere hydrogen på, men fagfeltet ligger ... -
Multiple aspects of plasticity in clutch size vary among populations of a globally distributed songbird
(Journal article, 2014)Plasticity in life-history characteristics can influence many ecological and evolutionary phenomena, including how invading organisms cope with novel conditions in new locations or how environmental change affects organisms ... -
Multiple Environmental Stressors: Biological Interactions Between Parameters of Climate Change and Perfluorinated Alkyl Substances in Fish
(Doctoral thesis at NTNU;2016:100, Doctoral thesis, 2016)Aquatic organisms continuously acclimatize to fluctuations in environment parameters and contaminant insult. The aim of this thesis was to investigate effects of combined exposure to quantifiable measures of climate ... -
Multiple shooting for training neural differential equations on time series
(Peer reviewed; Journal article, 2021)Neural differential equations have recently emerged as a flexible data-driven/hybrid approach to model time-series data. This work experimentally demonstrates that if the data contains oscillations, then standard fitting ... -
Multiple-Input Single-Output Control for Extending the Steady-State Operating Range—Use of Controllers with Different Setpoints
(Journal article; Peer reviewed, 2019)This paper deals with a case when multiple inputs are needed to cover the steady-state operating range. The most common implementation is to use split range control with a single controller. However, this approach has some ... -
Multiple-stressor effects in an apex predator: combined influence of pollutants and sea ice decline on lipid metabolism in polar bears
(Journal article; Peer reviewed, 2017)There is growing evidence from experimental and human epidemiological studies that many pollutants can disrupt lipid metabolism. In Arctic wildlife, the occurrence of such compounds could have serious consequences for ... -
Multipurpose peptides: The venoms of Amazonian stinging ants contain anthelmintic ponericins with diverse predatory and defensive activities
