Introduction - Oxford Energy Forum – Issue, 98

“…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. …”

Simulations of radiatively cooled magnetic reconnection driven by pulsed power by Datta, Rishabh, Crilly, Aidan, Chittenden, Jeremy P., Chowdhry, Simran, Chandler, Katherine, Chaturvedi, Nikita, Myers, Clayton E., Fox, William R., Hansen, Stephanie B., Jennings, Chris A., Ji, Hantao, Kuranz, Carolyn C., Lebedev, Sergey V., Uzdensky, Dmitri A., Hare, Jack D.

“…In this paper, we perform two- and three-dimensional simulations to model the MARZ (Magnetic Reconnection on Z) experiments, which are designed to access cooling rates in the laboratory necessary to investigate reconnection in a previously unexplored radiatively cooled regime. These simulations are performed in GORGON, an Eulerian two-temperature resistive magnetohydrodynamic code, which models the experimental geometry comprising two exploding wire arrays driven by 20 MA of current on the Z machine (Sandia National Laboratories). …”

Exchange bias and magnetoresistance effects in Ni50Mn50-yXy (X = In, Sn) alloys by Wang, Baomin

“…The large negative magnetoresistance is observed within the transformation regime across the first-order magnetic transition, which is correlated to the magnetic-field-induced phase transformation from antiferromagnetic martensite to ferromagnetic austenite. …”

Essays in interactional dynamics of financial markets by Chen, Zhenxi

“…Chapter 5 applies Markov-regime switching technique to show the existence of inter-market traders whose trading decision is based on the fundamental value of foreign market under a two-market framework. …”

Taliban resurgence in Afghanistan : the role of post-conflict reconstruction by Sadia Sulaiman

“…Subsequently, the Taliban-led insurgents re-emerged as a potent force by exploiting the Afghan people’s discontent, which arose from the absence of security, especially in the South and East of Afghanistan and the failure to rebuild the country’s economy, as a result of which the weak Karzai regime lost its legitimacy. The international community’s failure to make headway in reconstructing post-Bonn Afghanistan helped the Taliban to draw material and human resources for their movement from the disgruntled population. …”

The road to federalism : finding the middle ground in Nepal, Myanmar and Sri Lanka by Breen, Michael Gerard

“…In particular, when the secession risk is moderate, and when minority ethnic groups have a demonstrable infrastructural capacity, there are incentives for regime change agents from the dominant ethnic group to align with minority ethnic groups to pursue mutual goals of federalism and democratic reform. …”

Inter-organizational competition in humanitarian governance by Corsini, C

“…<p>In a world where humanitarian crises are increasing in severity and frequency, the humanitarian system is often described as a ‘competitive marketplace,’ an international regime densely populated by diverse actors – UN organizations, the Red Cross/Red Crescent Movement, international and local non-governmental organizations (NGOs), private entities, governments, and civil society – all vying for scarce resources from a limited pool of fatigued donors (Weiss 2013). …”

Tunable metasurfaces for active nanophotonics by Omar Abdelrahman Mohamed Abdelraouf

“…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

“…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

“…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. …”

100 THz optical switching with plasmonic metamaterial by Venkatram, Nalla, Stefano, Vezzol, João, Valente, Sun, Handong, Nikolay, Zheludev

“…Finally we evaluate the effect of non linearities, showing that the best coherent modulation is obtained in a very low power regime. We also evaluate the wavelength dependent coherent modulation; maximum modulation is at plasmonic peak.…”

Understanding Drivers of Deforestation using Games on Spatial Networks by Seby, Jean-Baptiste

“…Interestingly, we identify a regime shift (or phase transition) as the local network effect and level of coupling between activities vary. …”

Imaging the wakes of jets with energy-energy-energy correlators by Bossi, Hannah, Kudinoor, Arjun S., Moult, Ian, Pablos, Daniel, Rai, Ananya, Rajagopal, Krishna

“…We find that hadrons originating from wakes are the dominant contribution to the three-point correlator in the kinematic regime in which the three points are well-separated in angle, forming a roughly equilateral triangle. …”

A reformulation of additive models by Wozniakowski, Alex

“…Yet, the traditional methodology neglects the means to explicitly incorporate prior knowledge into the fit of an additive model, which is of great practical importance in regression tasks, especially in the low training example regime, where entirely data-driven learning is not always feasible. …”

Electrical characterization of bias temperature instability in MOSFETs with the ultrathin SiON and la-doped HfSiO gate dielectrics by Du, Guoan.

“…Under certain stress voltage and temperature, the number of E'δ centers is saturated because the reaction of pre-existing oxygen vacancies at shallow regime reaches its dynamic balance. On the other hand, lengthening of the stress time allows the generation of deeper hole trap states arising greater structural relaxation through increased interaction with lattice phonons. …”

Modeling, optimization and thermal characterization of micropillar evaporator based high performance silicon vapor chamber by Wei, Mengyao

“…Investigation on wettability performance of micropillar structures was not systematically extended to a high temperature regime. In this thesis, we developed three semi-analytical models in predicting the capillary-limited dryout heat flux of uniform evaporators, biporous evaporators and sealed silicon vapor chambers. …”

“…This would have allowed efficient overplating and burial of early Martian crust in a stagnant-lid tectonic regime, in which the lithosphere comprised a single tectonic plate, with only the warmer, lower crust involved in mantle convection. …”

Prediction of stable perovskite quantum dots (QDs) using machine learning (ML) algorithms by Cheong, Ivan

“…However, they have not been widely studied, with applications limited to solar cells and catalytic activity, the full extent of possible applications are yet to be realised. At the nano regime the properties are often different and can be controlled, this is due to quantum confinement and larger surface to volume ratio, which can be adjusted by controlling the size, subsequently able to use for various application. …”

Theoretical study on forced convection filmwise condensation inside converging channels in the presence of a non-condensable gas by Liu, Pengfei, Ho, Jin Yao, Kandasamy, Ranjith, Wong, Teck Neng

“…When the air mass fraction is high (W=0.4), the enhancement ratio appears to be insensitive to the Reynolds number in the laminar and turbulent regime, respectively. In addition, the enhancement ratio generally increases as the air mass fraction increases.…”
