History dependence of the microstructure on time-dependent deformation during in-situ cooling of a nickel-based single-crystal superalloy by Panwisawas, Chinnapat, D’Souza, Neil, Collins, David M., Bhowmik, Ayan, Roebuck, Bryan

“…Time-dependent plastic deformation through stress relaxation and creep deformation during in-situ cooling of the as-cast single-crystal superalloy CMSX-4® has been studied via neutron diffraction, transmission electron microscopy, electro-thermal miniature testing, and analytical modeling across two temperature regimes. Between 1000 °C and 900 °C, stress relaxation prevails and gives rise to softening as evidenced by a decreased dislocation density and the presence of long segment stacking faults in γ phase. …”

Nanoparticle-induced chemoresistance: the emerging modulatory effects of engineered nanomaterials on human intestinal cancer cell redox metabolic adaptation by Wu, Zhuoran, Setyawati, Magdiel Inggrid, Lim, Hong Kit, Ng, Kee Woei, Tay, Chor Yong

“…By employing a conditioning and challenge treatment regime, we demonstrate that repeated exposure to a non-toxic dose of ZnO NPs (20 μM) could dampen the efficacy of cisplatin, paclitaxel and doxorubicin by 10-50% in monolayer culture and 3D spheroids of human colon adenocarcinoma cells. …”

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. …”

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

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. …”

A reformulation of additive models by Wozniakowski, Alex

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. …”
