Contact stresses associated with the wedge-lock mechanism in a prototype subsea pipeline recovery tool
(Peer reviewed; Journal article, 2019)This paper examines the contact stresses associated with the wedge-lock mechanism in a prototype subsea pipeline recovery tool (PRT) through numerical methods and experimental testing. The prototype PRT studied combines ... -
Gauged Wess-Zumino terms for a general coset space
(Peer reviewed; Journal article, 2019)The low-energy physics of systems with spontaneously broken continuous symmetry is dominated by the ensuing Nambu-Goldstone bosons. It has been known for half a century how to construct invariant Lagrangian densities for ... -
A New Modular Petri Net for Modeling Large Discrete-Event Systems: A Proposal Based on the Literature Study
(Peer reviewed; Journal article, 2019)Petri net is a highly useful tool for modeling of discrete-event systems. However, Petri net models of real-life systems are enormous, and their state-spaces are usually of infinite size. Thus, performing analysis on the ... -
Evidence on the Troubled Assets Relief Program, Bailout Size, Returns and Tail Risk
(Peer reviewed; Journal article, 2019)The US government launched the Troubled Assets Relief Program (TARP) in mid-September 2008. This article analyzes the market response to the TARP launch. We reject the null hypothesis that the bailout size has no effect ... -
Cooperation in Norwegian search and rescue services as seen by voluntary organizations.
(Peer reviewed; Journal article, 2019)The core concept of the search and rescue services is in Norwegian language described with the term samvirke, often translated into English by cooperation. In this article we will explore if samvirke is more than usually ... -
Development of a method for evaluation of measures used for winterization of offshore facilities and units
(Peer reviewed; Journal article, 2019)The environmental conditions in the Barents Sea include low temperatures, wind, snow and precipitation influencing safety, working environment, operations and equipment functionality. The conditions are not extreme compared ... -
Scanning the Medical Terrain : an aid to quicker adoption of guidelines
(Peer reviewed; Journal article, 2019)Guidelines exist in order to ensure efficient, effective and consistent provision of healthcare service. Unfortunately, existing guidelines are often not adopted in a timely manner, even to the point of being outdated at ... -
Nitrogen doped Carbon Nanotubes as Electrocatalyst for Oxygen Reduction Reaction
(Peer reviewed; Journal article, 2019)The oxygen reduction reaction on nitrogen doped multiwalled carbon nanotubes (N-MCNTs) is studied for its application for deoxygenation of seawater. N-MCNTs were synthesized using commercial MCNTs and polyaniline as nitrogen ... -
Exploits, advances, and challenges benefiting beyond Li-ion battery technologies
(Peer reviewed; Journal article, 2019)The battery market is undergoing quick expansion owing to the urgent demand for mobile devices, electric vehicles and energy storage systems, convoying the current energy transition. Beyond Li-ion batteries are of high ... -
Effective kinetic description of event-by-event pre-equilibrium dynamics in high-energy heavy-ion collisions
(Peer reviewed; Journal article, 2019)We develop a macroscopic description of the space-time evolution of the energy-momentum tensor during the pre-equilibrium stage of a high-energy heavy-ion collision. Based on a weak coupling effective kinetic description ... -
Real-time quantum dynamics, path integrals and the method of thimbles
(Peer reviewed; Journal article, 2019)Direct numerical evaluation of the real-time path integral has a well-known sign problem that makes convergence exponentially slow. One promising remedy is to use Picard-Lefschetz theory to flow the domain of the field ... -
Flow in AA and pA as an interplay of fluid-like and non-fluid like excitations
(Peer reviewed; Journal article, 2019)To study the microscopic structure of quark–gluon plasma, data from hadronic collisions must be confronted with models that go beyond fluid dynamics. Here, we study a simple kinetic theory model that encompasses fluid ... -
Open Humans: A platform for participant-centered research and personal data exploration
(Peer reviewed; Journal article, 2019)Background Many aspects of our lives are now digitized and connected to the internet. As a result, individuals are now creating and collecting more personal data than ever before. This offers an unprecedented chance for ... -
Insights into the potential of the Atlantic cod gut microbiome as biomarker of oil contamination in the marine environment
(Peer reviewed; Journal article, 2019)Background: Microorganisms are widespread in all environments, including in and on animal bodies. The gut microbiome has an essential influence on fish health, and is affected by several persistent and harmful organic and ... -
The effect of integral control in oscillatory and chaotic reaction kinetic networks
(Peer reviewed; Journal article, 2019)Integral control is ubiquitously used in industrial processes to keep variables robustly regulated at a given setpoint. Integral control is also present in many biological systems where it, implemented through reaction ... -
Highly thermostable carboxylic acid reductases generated by ancestral sequence reconstruction
(Peer reviewed; Journal article, 2019)Carboxylic acid reductases (CARs) are biocatalysts of industrial importance. Their properties, especially their poor stability, render them sub-optimal for use in a bioindustrial pipeline. Here, we employed ancestral ... -
Spontaneous momentum dissipation and coexistence of phases in holographic Horndeski theory
(Peer reviewed; Journal article, 2019)We discuss the possible phases dual to the AdS hairy black holes in Horndeski theory. In the probe limit breaking the translational invariance, we study the conductivity and we find a nontrivial structure indicating a ... -
Network-Aware Availability Modeling of an End-to-End NFV-Enabled Service
