Subexponential Parameterized Algorithms and Kernelization on Almost Chordal Graphs
(Journal article; Peer reviewed, 2020)We study algorithmic properties of the graph class Chordal-ke, that is, graphs that can be turned into a chordal graph by adding at most k edges or, equivalently, the class of graphs of fill-in at most k. We discover that ... -
Subexponential Parameterized Algorithms and Kernelization on Almost Chordal Graphs
(Journal article; Peer reviewed, 2021)We study algorithmic properties of the graph class CHORDAL−ke, that is, graphs that can be turned into a chordal graph by adding at most k edges or, equivalently, the class of graphs of fll-in at most k. It appears that a ... -
Subglacial sediment distribution from constrained seismic inversion, using MuLTI software: examples from Midtdalsbreen, Norway
(Journal article; Peer reviewed, 2019)Fast ice flow is associated with the deformation of subglacial sediment. Seismic shear velocities, Vs, increase with the rigidity of material and hence can be used to distinguish soft sediment from hard bedrock substrates. ... -
Subgraph Complementation
(Journal article; Peer reviewed, 2020-02)A subgraph complement of the graph G is a graph obtained from G by complementing all the edges in one of its induced subgraphs. We study the following algorithmic question: for a given graph G and graph class G, is there ... -
Subjective and objective sleep among air ambulance personnel
(Journal article; Peer reviewed, 2021)The present study aimed to investigate the effects of shift work on sleep among pilots and Helicopter Emergency Medical Service crew members (HCM) in the Norwegian Air Ambulance. Sleep was assessed by diaries and actigraphy ... -
Subjective health complaints and exposure to tick-borne infections in southern Norway
(Journal article; Peer reviewed, 2020)Objectives: Whether tick‐borne infections can cause chronic subjective health complaints is heavily debated. If such a causal connection exists, one would expect to find more health complaints among individuals exposed to ... -
Subjective symptoms and serum methadone concentrations: what should guide dose adjustments in methadone maintenance treatment? A naturalistic cohort study from Norway
(Journal article; Peer reviewed, 2021)Background: There is little evidence-based guidance on how to optimize methadone dosages among patients with opioid addiction undergoing methadone maintenance treatment (MMT). This study aims to investigate whether ... -
Subsea permafrost carbon stocks and climate change sensitivity estimated by expert assessment
(Journal article; Peer reviewed, 2020)The continental shelves of the Arctic Ocean and surrounding seas contain large stocks of organic matter (OM) and methane (CH4), representing a potential ecosystem feedback to climate change not included in international ... -
Subsequent ipsi- and contralateral femoral fractures after intramedullary nailing of a trochanteric or subtrochanteric fracture: a cohort study on 2012 patients
(Journal article; Peer reviewed, 2022-04-28)Background: The literature is inconclusive as to whether an intramedullary nail changes the distribution of a subsequent ipsi- or contralateral fracture of the femur. We have compared the incidence, localisation, and ... -
Substance use and symptoms of mental health disorders: a prospective cohort of patients with severe substance use disorders in Norway
(Journal article; Peer reviewed, 2021-02-27)Background:There is high co-occurrence of substance use disorders (SUD) and mental health disorders. We aimedto assess impact of substance use patterns and sociodemographic factors on mental health distress using the ... -
Substance-related problems among adolescents in child welfare services: A comparison between individuals receiving in-home services and those in foster care
(Journal article; Peer reviewed, 2020-11)Background and aims The literature base on substance use among adolescents who receive interventions from child welfare services (CWS) in Nordic countries is limited. The purpose of this study was to investigate whether ... -
Substance-Related Problems in Adolescents with ADHD-Diagnoses: The Importance of Self-Reported Conduct Problems
(Journal article; Peer reviewed, 2022)Background: Attention-deficit/hyperactivity disorder (ADHD) is a known risk factor for substance-related problems (SRP) during adolescence, but the nature of this relationship and the importance of co-occurring conduct ... -
Substantial changes in inflammatory and cardiovascular biomarkers in patients with autonomous cortisol secretion
(Journal article; Peer reviewed, 2023)Objective To map inflammatory biomarkers in patients with autonomous cortisol secretion (ACS) and overt Cushing syndrome (CS). Method Observational study including serum from prospectively included patients with ACS ... -
Substantial Sparing of Organs at Risk with Modern Proton Therapy in Lung Cancer, but Altered Breathing Patterns Can Jeopardize Target Coverage
(Journal article; Peer reviewed, 2022-03-08)Enhancing treatment of locally advanced non-small cell lung cancer (LA-NSCLC) by using pencil beam scanning proton therapy (PBS-PT) is attractive, but little knowledge exists on the effects of uncertainties occurring between ... -
Substantial spatial variation in glacial erosion rates in the Dronning Maud Land Mountains, East Antarctica
(Journal article; Peer reviewed, 2021)The coast-parallel Dronning Maud Land (DML) mountains represent a key nucleation site for the protracted glaciation of Antarctica. Their evolution is therefore of special interest for understanding the formation and ... -
Substituted decision making and the dispositional choice account
(Journal article; Peer reviewed, 2018)There are two main ways of understanding the function of surrogate decision making in a legal context: the Best Interests Standard and the Substituted Judgment Standard. First, we will argue that the Best Interests Standard ... -
Substituted Two- To Five-Ring Polycyclic Aromatic Compounds Are Potent Agonists of Atlantic Cod (Gadus morhua) Aryl Hydrocarbon Receptors Ahr1a and Ahr2a
(Journal article; Peer reviewed, 2021)Polycyclic aromatic hydrocarbons (PAHs) are among the most toxic and bioavailable components found in petroleum and represent a high risk to aquatic organisms. The aryl hydrocarbon receptor (Ahr) is a ligand-activated ... -
Substorm Current Wedge: Energy Conversion and Current Diversion
(Journal article; Peer reviewed, 2020)Using a magnetohydrodynamic simulation of magnetotail reconnection, flow bursts, and dipolarization, we further investigate the current diversion and energy flow and conversion associated with the substorm current wedge ... -
