Risk factors in stock returns of U.S. oil and gas companies: evidence from quantile regression analysis
(Peer reviewed; Journal article, 2022)The boom and bust in oil prices during the last two decades have attracted many investors to oil and gas companies in search of returns and risk diversification benefits. This study analyzes the impact of several risk ... -
Data-driven sensitivity analysis of complex machine learning models: A case study of directional drilling
(Peer reviewed; Journal article, 2020-12)Classical sensitivity analysis of machine learning regression models is a topic sparse in literature. Most of data-driven models are complex black boxes with limited potential of extracting mathematical understanding of ... -
Quench, thermalization, and residual entropy across a non-Fermi liquid to Fermi liquid transition
(Peer reviewed; Journal article, 2020)We study the thermalization, after sudden and slow quenches, in an interacting model having a quantum phase transition from a Sachdev-Ye-Kitaev (SYK) non-Fermi liquid (NFL) to a Fermi liquid (FL). The model has SYK fermions ... -
Fluid-sensitive migration mechanisms predict association between metastasis and high interstitial fluid pressure in pancreatic cancer
(Peer reviewed; Journal article, 2022)A remarkable feature in pancreatic cancer is the propensity to metastasize early, even for small, early stage cancers. We use a computer-based pancreatic model to simulate tumor progression behavior where fluid-sensitive ... -
Usability, acceptability and feasibility of a novel technology with visual guidance with video and audio recording during newborn resuscitation: a pilot study
(Peer reviewed; Journal article, 2022)Objective Inadequate adherence to resuscitation for noncrying infants will have poor outcome and thus rationalise a need for real-time guidance and quality improvement technology. This study assessed the usability, ... -
Two Birds with One Stone: Concurrent Ligand Removal and Carbon Encapsulation Decipher Thickness-Dependent Catalytic Activity
(Peer reviewed; Journal article, 2022)A carbon shell encapsulating a transition metal-based core has emerged as an intriguing type of catalyst structure, but the effect of the shell thickness on the catalytic properties of the buried components is not well ... -
Transition Metal−N/Graphene for advanced Lithium–Sulfur Batteries: A first principles study
(Peer reviewed; Journal article, 2022)Developing highly efficient anchoring materials with strong adsorption to lithium polysulfides to suppress ‘shuttling effect’ is crucial to address the short cycling life issue of lithium sulfur batteries. Herein, we ... -
Aerodynamic influence of an alpine skier’s arms
(Peer reviewed; Journal article, 2022)Understanding how postural changes in alpine skiing affect the overall aerodynamic drag is highly important for enhancing performance. Although the arm configuration of the athlete can have a significant impact on the ... -
Numerical Investigation of Flow around Two Tandem Cylinders in the Upper Transition Reynolds Number Regime Using Modal Analysis
(Peer reviewed; Journal article, 2022)Flow around two tandem cylinders at Re = 3.6 × 106 for different center-to-center spacing ratio (L/D) is investigated numerically using two-dimensional (2D) Unsteady Reynolds-Averaged Navier–Stokes (URANS) equations combined ... -
Experimental Investigation and Numerical Modeling of Two-Phase Flow Development and Flow-Induced Vibration of a Multi-Plane Subsea Jumper
(Peer reviewed; Journal article, 2022)As an essential component in the offshore oil and gas industry, subsea jumpers are likely to encounter the cyclic-induced stresses caused by the alternating movement of gas plugs and liquid slugs while transporting a ... -
Butterfly glioblastoma: Clinical characteristics, treatment strategies and outcomes in a population-based cohort
(Peer reviewed; Journal article, 2022)Butterfly glioblastoma is a rare subgroup of glioblastoma with a bihemispheric tumor crossing the corpus callosum, and is associated with a dismal prognosis. Prognostic factors are previously sparsely described and optimal ... -
Modeling a predictive maintenance management architectureto meet industry 4.0 requirements: A case study
(Peer reviewed; Journal article, 2020)Industry 4.0 is the latest paradigm of industrial production enabling a new level of organizing and controlling the entire value chain within a product life cycle by creating a dynamic and real-time understanding of ... -

The Role of Micro Gas Turbines in Energy Transition
(Peer reviewed; Journal article, 2022)In the progressively rising decentralized energy market, micro gas turbines (MGT) are seen with great potential owing to their low emissions, fuel flexibility, and low maintenance. The current transformation in the landscape ... -
Feasibility Study of a Novel Open Ocean Aquaculture Ship Integrating with a Wind Turbine and an Internal Turret Mooring System
(Peer reviewed; Journal article, 2022)Marine aquaculture has been expanded into more remote areas due to the increasing demand for high value-added fish products, bringing more challenges in fuel supply and mooring safety to open ocean aquaculture farms. ... -
Improved background subtraction and a fresh look at jet sub-structure in JEWEL
(Peer reviewed; Journal article, 2022)Interactions of hard partons in the Quark Gluon Plasma (QGP) created with relativistic heavy ion collisions lead to characteristic modifications of the internal structure of reconstructed jets. A large part of the observed ... -
