    Introduction - Oxford Energy Forum – Issue, 98

    Published 2015
    “…The problem is that lower oil revenues also affect industry, forcing operators to review their investment portfolios to focus on the best regimes and geological prospects.</p> <p>The region’s recent positive developments are taking place against a background where a large number of countries in the region (including Argentina, Venezuela, Bolivia, Ecuador, French Guyana, and Suriname) have fallen out of favour with oil and gas investors, in some cases for a number of years. …”

    Tunable metasurfaces for active nanophotonics by Omar Abdelrahman Mohamed Abdelraouf

    Published 2023
    “…In addition, we experimentally showed tunable light sources based on the amplified spontaneous emission concept in visible and near-infrared regimes by designing two different tunable metasurfaces that support the bound states in the continuum resonance. …”

    Carbon nanomaterial/thermoplastic polyurethane composites for sports application : preparation, characterization and simulation by Jing, Qifei

    Published 2016
    “…The finite-element analysis provided quantification of the effect of GO enhancement on the large-deflection bending performance of PU for regimes typical for shoe soles and can be used as a basis for optimization of real composite products.…”

    Wear behaviour of NiTi shape memory alloys by Yan, Lina

    Published 2016
    “…Furthermore, the wear behaviour of the forged ingot Ni 48.2at% Ti SMA was studied in three temperature regimes where different phases were present, that is, fully martensitic phase when T < Mf, fully austenitic phase when Mf < T < Af, and martensitic phase coexisted with austenitic phase when T > Af. …”

    GPU-based commonsense reasoning for real-time query answering and multimodal analysis by Tran, Ha Nguyen

    Published 2017
    “…Secondly, in order to reason and retrieve information on rule-based knowledge bases, the thesis introduces gSparql, a fast and scalable inference and querying method on mass-storage RDF data with rule-based entailment regimes. Our approach accepts different rulesets and executes the reasoning process at query time when the inferred triples are determined by the set of triple patterns defined in the query. …”

    Towards electrically injected colloidal semiconductor lasers by Thung, Yi Tian

    Published 2025
    “…The NPL-VCSEL demonstrated a low lasing threshold of 21.6 W cm-2 with a single-mode Q-factor of 11800 under continuous-wave (cw) excitation, with good agreement between the cw-pumped lasing spectra and the ps pulse-pumped lasing spectra. to highlighting the NPL-VCSEL’s robustness under different optical pumping regimes, I demonstrated the NPL-VCSEL’s performance under continuous wave optical pump, affirming the suitability of the colloidal NPLs as the preferred gain medium to realize the desired electrically injected colloidal semiconductor lasers. …”

    Studies on plasma assisted molecular beam epitaxial growth of GaN-based multilayer heterostructures on Si for photodetector application by Zheng, Yi

    Published 2019
    “…Tunability of band gap and the possibility of formation of heterostructures with group III-nitride materials allow the design of complex structures to detect both UV and infra-red (IR) spectral regimes (multi band) on a single chip. By growing AlGaN/GaN multiple quantum well layers, IR detector can also be obtained, which means IR and UV detector can be achieved using the same material. …”
