Infectious diseases depend on intensified social intercourse within large cities, resulting in a super-linear allometric scaling law with city size. But how this scaling relationship changes throughout an evolving pandemic is seldom studied and remains unclear. Here, we investigate allometric...

Tournament competition is viewed as motivating bureaucrats in promoting growth. This paper examines how this incentive leads to economic performance manipulation. Using data from Chinese cities, the analysis shows that performance exaggeration increases over the course of the first term of the...

In this paper, the exergoeconomic analysis was conducted to an existing ultra-supercritical coal-fired power plant in China to understand the cost-formation process, to evaluate the economic performance of each component and to find possible solutions for more cost-effective designs. The total...

Utilizing 1998–2020 matched data consisting of a sample of both listed firms and always-non-listed firms, this study establishes the causal impacts of listing on the financial behavior of private firms in China. Our results are as follows. First, initial public offerings (IPOs) cause private...

While anti-corruption policies are generally believed to be crucial for investment and economic growth, we argue that such policies may backfire by impairing local officials’ incentives to grow the economy in a society featuring weak formal institutions and a state-led development model where...

Health, as an important human capital, is fundamental for bureaucrats to properly perform duties so as to deliver the function of the state. Based on a nationally representative longitudinal survey and using a difference-in-differences identification strategy, we study whether and how the recent...

Adjustment of the pH value is an effective method to control the morphology of nanostructures. In this work, the W18O49 nanowires with crystalline@amorphous homogenous core-shell composite structures were prepared by controlling the pH of the precursor during the hydrothermal reaction. Due to...

Compressed air energy storage (CAES) is a large-scale technology that provides long-duration energy storage. It is promising for balancing the large-scale penetration of intermittent and dispersed sources of power, such as wind and solar power, into electric grids. The existing CAES plants...

Compared to conventional vehicles Hybrid Electric Vehicles (HEVs) provide fairly high fuel economy with lower emissions. To enhance HEV performance in terms of fuel economy and emissions, and ensure user satisfaction with driving performance, the need for simultaneous optimization for the main...

In this study, an improved CO₂ separation and purification system is proposed based on in-depth analyses of cryogenic separation and distillation theory as well as the phase transition characteristics of gas mixtures containing CO₂. Multi-stage compression, refrigeration, and separation are...
