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 ... -
Experimental investigation of residual stress distribution on girth welds fabricated at proximity using neutron diffraction technique
(Peer reviewed; Journal article, 2022)Maintaining minimum distance between repair and existing welds often becomes impractical due to the presence of compact layouts, original welds of branches, nozzles, etc. on offshore structural elements, pipelines, and ... -
Experimental Investigation on Effect of Weight Fraction of Sisal Fiber on Mechanical Properties of Sisal-E-Glass Hybrid Polymer Composites
(Peer reviewed; Journal article, 2023)Currently, hybridizing natural fibers with synthetic fiber is considered as the best solution for reducing the environmental pollution and the cost of materials. This is due to the lower mechanical properties and high water ... -
Families of Proper Holomorphic Embeddings and Carleman-Type Theorem with parameters
(Peer reviewed; Journal article, 2023)We solve the problem of simultaneously embedding properly holomorphically into C2 a whole family of n-connected domains Omega_r in P1 such that none of the components of P1 \ Omega_r reduces to a point, by constructing a ... -
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. ... -
Field theories with higher-group symmetry from composite currents
(Peer reviewed; Journal article, 2021)Higher-form symmetries are associated with transformations that only act on extended objects, not on point particles. Typically, higher-form symmetries live alongside ordinary, point-particle (0-form), symmetries and they ... -
Flavor structure of GUTs and uncertainties in proton lifetime estimates
(Peer reviewed; Journal article, 2019)We study the flavor aspects of proton lifetime estimates in simple grand-unified models, paying particular attention to their inherent fragility due to the notorious lack of control of some of the key parameters governing ... -
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 ... -
Further insight into the genetic diversity of Entamoeba coli and Entamoeba hartmanni
(Peer reviewed; Journal article, 2022)Despite the species' wide distribution, studies of the genetic diversity within Entamoeba coli and Entamoeba hartmanni remain limited. In the present study, we provide further insight into the genetic diversity of both ... -
Further Investigation of Solvent Synergists for Improved Performance of Poly(N-vinylcaprolactam)-Based Kinetic Hydrate Inhibitors
(Peer reviewed; Journal article, 2021)Poly(N-vinylcaprolactam) (PVCap) and related copolymers have been used as kinetic hydrate inhibitors (KHIs) to combat gas hydrate formation in oil and gas field production flow lines. It is known that the addition of certain ... -
Gaidai-Xing reliability method validation for 10-MW floating wind turbines
(Peer reviewed; Journal article, 2023)In contrast to well-known bivariate statistical approach, which is known to properly forecast extreme response levels for two-dimensional systems, the research validates innovative structural reliability method, which is ... -
Gain-scheduled observer-based consensus for linear parameter varying multi-agent systems
(Peer reviewed; Journal article, 2022)This paper investigates the gain-scheduled observer-based consensus of linear parameter varying (LPV) multi-agent systems (MASs). The main contribution of the paper is that, differently from LPV observer-based consensus ... -
Genomics and transcriptomics yields a system-level view of the biology of the pathogen Naegleria fowleri
(Peer reviewed; Journal article, 2021)Background The opportunistic pathogen Naegleria fowleri establishes infection in the human brain, killing almost invariably within 2 weeks. The amoeba performs piece-meal ingestion, or trogocytosis, of brain material ... -
Geometric surfaces: An invariant characterization of spherically symmetric black hole horizons and wormhole throats
(Peer reviewed; Journal article, 2021)We consider a spherically symmetric line element which admits either a black hole geometry or a wormhole geometry and show that in both cases the apparent horizon or the wormhole throat is partially characterized by the ... -
A GIT construction of degenerations of Hilbert schemes of points
(Peer reviewed; Journal article, 2019)We present a Geometric Invariant Theory (GIT) construction which allows us to construct good projective degenerations of Hilbert schemes of points for simple degenerations. A comparison with the construction of Li and Wu ... -
Granular sludge bed processes in anaerobic digestion of particle-rich substrates
(Peer reviewed; Journal article, 2019-07)Granular sludge bed (GSB) anaerobic digestion (AD) is a well-established method for efficient wastewater treatment, limited, however, by the wastewater particle content. This review is carried out to investigate how and ... -
Harmfulness mapping for the Pechora Sea
(Peer reviewed; Journal article, 2019)Pechora Sea is characterized with many species including birds, fishes, benthic fauna and marine mammals. The food chains in the Pechora Sea ecosystems are simple and vulnerable to contamination even in a small concentration ... -
Heavy quarkonium in extreme conditions
(Peer reviewed; Journal article, 2020)In this report we review recent progress achieved in the understanding of heavy quarkonium under extreme conditions from a theory perspective. Its focus lies both on quarkonium properties in thermal equilibrium, as well ... -
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 ... -
Homeostasis at different backgrounds: The roles of overlayed feedback structures in vertebrate photoadaptation
(Peer reviewed; Journal article, 2023)We have studied the resetting behavior of eight basic integral controller motifs with respect to different but constant backgrounds. We found that the controllers split symmetrically into two classes: one class, based on ...
