By monitoring the unloaded signal in the shielding environment of the ground laboratory, it is observed that the signal fluctuation range is almost concentrated between − 0.02 and 0.02 pC, indicating the signal in this amplitude range could be considered noise interference (Fig. 7). Therefore, ...

They are not capable of giving quantitative measurements on cement quality, and combined with the aforementioned material and operational challenges, it is evident that a risk of leaks is present. Even though NORSOK D-010 (2013) provides zero leak acceptance criteria for abandoned wells, there are...
Understanding coal permeability as impacted by thermal damage is crucial to the detection of coal and gas hazards in deep coal mining. In this study, tri-axial compression experiments were performed to examine the damage and the permeability evolution process of methane-containing coal under different...
Budget request of $813.3 billion for national defense. The FY 2023 DoD Budget request is a 4.1% increase from the FY 2022 enacted amount. The US military expenditure accounts for nearly half of the world total and is equivalent to the military expenditure of more than 100 countries combined...
The complex connections between China and the US have comprised a mixture of economic and financial interdependence for years that is combined with a strategic rivalry. Trump’s influence on Australia-China relations International Relations experts have often coined Australia as America's 'little brother...
1e). We model it by a stochastic process Xt, which, depending on a control parameter λ < 0, is at risk of undergoing a critical transition through a saddle-node bifurcation for λ = λc = 0. The system is initially in a statistically stable state, i.e., it follows ...
Combined with the large number of real-life cases from developed countries discussed in the introduction, this phenomenon does exist and we proposed the hypothesis below: H1: The current shape of the global EKC is N-shaped. H2: The N-shaped EKC remains robust with additional variables. The ...
Natural dew is a ubiquitous phenomenon, which can be encountered at night in many places of the world when the conditions for its formation are met (clear sky, high relative humidity, low windspeed). Dew has been long studied by agrometeorologists for its impact in agriculture [1,2,3], po...
Based on this limited sample, a 4 -h battery that is sized at roughly 25 % of the PV capacity adds about $4/MWh-delivered to the overall PPA price for the combined plant. As the battery capacity increases to 50 % and 75 % of the PV capacity, the levelized battery adder increases ...
