Design and Early Age Performance of Sustainable One-Part Geopolymers for Well Cementing
(Peer reviewed; Journal article, 2023-10)One-part geopolymers, known as “just add water” (JAW), alkali-activated formulation is presented in this work. This work reveals the design and development of short-term properties of JAW geopolymers for use in oilwell ... -
Identification of the flux function of nonlinear conservation laws with variable parameters
(Peer reviewed; Journal article, 2023-09)Machine learning methods have in various ways emerged as a useful tool for modeling the dynamics of physical systems in the context of partial differential equations (PDEs). Nonlinear conservation laws (NCLs) of the form ... -
A new variational discretization technique for initial value problems bypassing governing equations
(Peer reviewed; Journal article, 2023-03)Motivated by the fact that both the classical and quantum description of nature rest on causality and a variational principle, we develop a novel and highly versatile discretization prescription for classical initial value ... -
Rheological Compatibility of a Hardening Spacer Fluid and Oil-based Drilling Fluid
(Peer reviewed; Journal article, 2023-08)In the placement process of the cement slurry, treatment fluids such as the spacer are pumped ahead of the cementitious slurry to minimize the contamination of the slurry by drilling fluid and ensure superior bonding to ... -
Trojan Spoofing: A Threat to Critical Infrastructure
(Peer reviewed; Journal article, 2023)This article explores the phenomenon of location spoofing – where the spoofer is able to ‘teleport’ systems in and out of defined locations, either for the purpose of infiltration into no-go zones or for the ‘teleportation’ ... -
Structural identifiability of biomolecular controller motifs with and without flow measurements as model output
(Peer reviewed; Journal article, 2023-08)Controller motifs are simple biomolecular reaction networks with negative feedback. They can explain how regulatory function is achieved and are often used as building blocks in mathematical models of biological systems. ... -
Factors contributing to healthcare professionals’ adaptive capacity with hospital standardization: a scoping review
(Peer reviewed; Journal article, 2023-07)Background Certain factors contribute to healthcare professionals’ adaptive capacities towards risks, challenges, and changes such as attitudes, stress, motivation, cognitive capacity, group norms, and teamwork. However, ... -
Learning tools used to translate resilience in healthcare into practice: a rapid scoping review
(Peer reviewed; Journal article, 2023-08)Background Historically, efforts to improved healthcare provisions have focussed on learning from and understanding what went wrong during adverse events. More recently, however, there has been a growing interest in seeking ... -
cdem: A macOS program for discrete element modeling of tectonic structures
(Peer reviewed; Journal article, 2023-08)cdem is a macOS document-based application for two-dimensional discrete element modeling of tectonic structures and their associated deformation. Documents encapsulate simulations that can be run and explored simultaneously. ... -
Identification of diagnostic and prognostic biomarkers of PD using a multiplex proteomics approach
(Peer reviewed; Journal article, 2023-10)Given the complexity of Parkinson's disease (PD), achieving acceptable diagnostic and prognostic accuracy will require the support of a panel of diverse biomarkers. We used Proximity extension assays to measure a panel of ... -
Optimizing support vector machines and autoregressive integrated moving average methods for heart rate variability data correction
(Peer reviewed; Journal article, 2023-09)Heart rate variability (HRV) is the variation in time between successive heartbeats and can be used as an indirect measure of autonomic nervous system (ANS) activity. During physical exercise, movement of the measuring ... -
Stakeholder perspectives on the preferred service ecosystem for senior citizens living at home: a qualitative interview study
(Peer reviewed; Journal article, 2023-09)BACKGROUND: Most senior citizens want to live independently at home as long as possible. The World Health Organization recommends an age-friendly community approach by transforming the service ecosystem for senior citizens ... -
Use of Suctioning during Newborn Resuscitation and Its Effects on Heart Rate in a Low-Resource Setting, Tanzania
(Peer reviewed; Journal article, 2023-09)Suctioning of newborns immediately after birth, as part of delivery room resuscitation, is only recommended if the airway is obstructed. The aim of this study was to describe the use of suctioning during newborn resuscitation ... -
Medication-free mental health treatment: a focus group study of milieu therapeutic settings
(Peer reviewed; Journal article, 2023)Background Medication-free treatment within mental health care aims to offer therapeutic support as an alternative to psychotropic medication. Introducing milieu therapy for severely mentally ill persons in a medication-free ... -
Zonal Isolation Material for Low-Temperature Shallow-Depth Application: Evaluation of Early Properties Development
(Peer reviewed; Journal article, 2023)Shallow-depth cementing presents unique challenges due to its low temperature and low pore pressure characteristic. The curing process of the cementitious material is typically prolonged at low temperatures resulting in a ... -
A Second-Order Finite Volume Method for Field-Scale Reservoir Simulation
(Peer reviewed; Journal article, 2023-08)Subsurface reservoirs are large complex systems. Reservoir flow models are defined on complex grids that follow geology with relatively large block sizes to make consistent simulations feasible. Reservoir engineers rely ... -
Effect of urban vs. remote settings on prehospital time and mortality in trauma patients in Norway: a national populationbased study
(Peer reviewed; Journal article, 2023-10)Background Norway has a diverse population pattern and often long transport distances from injury sites to hospitals. Also, previous studies have found an increased risk of trauma-related mortality in remote areas in ... -
