Extending Whitney's extension theorem: nonlinear function spaces
(Journal article; Peer reviewed, 2021)We consider a global, nonlinear version of the Whitney extension problem for manifold-valued smooth functions on closed domains , with non-smooth boundary, in possibly non-compact manifolds. Assuming is a submanifold with ... -
Extension of the hard-sphere model for particle-flow simulations
(Journal article; Peer reviewed, 2020)Discrete element methods require appropriate models for particle-particle collisions. Usually, researchers use soft-sphere types of models where the collision dynamics is solved numerically. This makes the simulation ... -
Extensions in graph normal form
(Journal article; Peer reviewed, 2022)Graph normal form, introduced earlier for propositional logic, is shown to be a normal form also for first-order logic. It allows to view syntax of theories as digraphs, while their semantics as kernels of these digraphs. ... -
Extensive bidirectional genetic overlap between bipolar disorder and cardiovascular disease phenotypes
(Journal article; Peer reviewed, 2021)Patients with bipolar disorder (BIP) have a high risk of cardiovascular disease (CVD), despite considerable individual variation. The mechanisms underlying comorbid CVD in BIP remain largely unknown. We investigated polygenic ... -
Extent and Volume of Lava Flows Erupted at 9°50′N, East Pacific Rise in 2005–2006 From Autonomous Underwater Vehicle Surveys
(Journal article; Peer reviewed, 2022)Seafloor volcanic eruptions are difficult to directly observe due to lengthy eruption cycles and the remote location of mid-ocean ridges. Volcanic eruptions in 2005–2006 at 9°50′N on the East Pacific Rise have been well ... -
External Developmental Assets and Positive Identity Among Emerging Adults in Norway, Romania, Slovenia, and Turkey
(Journal article; Peer reviewed, 2021)The present study adopts The Developmental Assets and Positive Youth Development (PYD) perspectives which (in contrast to the deficit-based approaches which highlight risks and deficit in youth development) claim that young ... -
External Hydrocephalus as a Cause of Infant Subdural Hematoma: Epidemiological and Radiological Investigations of Infants Suspected of Being Abused
(Journal article; Peer reviewed, 2022)Background Acute subdural hematoma (ASDH) and chronic subdural hematoma (CSDH) in infants have been regarded as highly specific for abuse. Other causes of CSDH have not been investigated in a large population. Purpose The ... -
An external quality assessment feasibility study; cross laboratory comparison of haemagglutination inhibition assay and microneutralization assay performance for seasonal influenza serology testing: A FLUCOP study
(Journal article; Peer reviewed, 2023)Introduction: External Quality Assessment (EQA) schemes are designed to provide a snapshot of laboratory proficiency, identifying issues and providing feedback to improve laboratory performance and inter-laboratory agreement ... -
External validation of SAPS II score reported to the Norwegian Intensive Care and Pandemic Registry (NIPaR)
(Journal article; Peer reviewed, 2023)Background: Simplified Acute Physiology Score II (SAPS II) is a mortality prediction model widely used to compensate for differences between intensive care units (ICU) in benchmarking and research. Accuracy of SAPS II is ... -
External validation of the RISC, RISC-Malawi, and PERCH clinical prediction rules to identify risk of death in children hospitalized with pneumonia
(Journal article; Peer reviewed, 2021)Background: Existing scores to identify children at risk of hospitalized pneumonia-related mortality lack broad external validation. Our objective was to externally validate three such risk scores. Methods: We applied the ... -
Extra-pair paternity explains cooperation in a bird species
(Journal article; Peer reviewed, 2022)In many social animals, females mate with multiple males, but the adaptive value of female extra-pair mating is not fully understood. Here, we tested whether male pied flycatchers (Ficedula hypoleuca) engaging in extra-pair ... -
The extracellular bone marrow microenvironment — a proteomic comparison of constitutive protein release by in vitro cultured osteoblasts and mesenchymal stem cells
(Journal article; Peer reviewed, 2021)Mesenchymal stem cells (MSCs) and osteoblasts are bone marrow stromal cells that contribute to the formation of stem cell niches and support normal hematopoiesis, leukemogenesis and development of metastases from distant ... -
Extracellular DNA concentrations in various aetiologies of acute kidney injury
(Journal article; Peer reviewed, 2022)Extracellular DNA (ecDNA) in plasma is a non-specific biomarker of tissue damage. Urinary ecDNA, especially of mitochondrial origin, is a potential non-invasive biomarker of kidney damage. Despite prominent tissue damage, ... -
Extracellular Vesicles Derived from Primed Mesenchymal Stromal Cells Loaded on Biphasic Calcium Phosphate Biomaterial Exhibit Enhanced Macrophage Polarization
(Journal article; Peer reviewed, 2022)Mesenchymal stromal cells (MSC) loaded on biphasic calcium phosphate biomaterial (MSC + BCP) have been used as an advanced therapy medicinal product to treat complex maxillofacial bone defects in patients. Further, MSC-derived ... -
Extracting Rules from Neural Networks with Partial Interpretations
(Journal article; Peer reviewed, 2022)We investigate the problem of extracting rules, expressed in Horn logic, from neural network models. Our work is based on the exact learning model, in which a learner interacts with a teacher (the neural network model) via ... -
Extracting Sign Language Articulation from Videos with MediaPipe
(Chapter, 2023)This paper concerns evaluating methods for extracting phonological information of Swedish Sign Language signs from video data with MediaPipe’s pose estimation. The methods involve estimating i) the articulation phase, ii) ... -
Extracting Users: Regimes of Engagement in Norwegian Smart Electricity Transition
(Journal article; Peer reviewed, 2021)Recent efforts to involve digital technologies and renewables in the electricity grid have placed users at center stage in the legitimation of energy transitions. This move has been paralleled by an emphasis on users and ... -
Extraction of form factors from a four-dimensional angular analysis of ¯B→D∗ℓ−¯νℓ
(Journal article; Peer reviewed, 2019-08-30)An angular analysis of the decay ¯B→D∗ℓ−¯νℓ, ℓ∈{e,μ}, is reported using the full e+e−collision data set collected by the BABAR experiment at the Υ(4S) resonance. One B meson from the Υ(4S)→B¯B decay is fully reconstructed ... -
Extrapolating from model organisms in pharmacology
(Chapter, 2020)In this chapter we explore the process of extrapolating causal claims from model organisms to humans in pharmacology. We describe and compare four strategies of extrapolation: enumerative induction, comparative process ... -
