Abstract ：
The article selects socioeconomic data related to 146 prefecture-level cities included in nine city clusters from 2014 to 2018 to establish a city-level socioeconomic system in China. A sensitivity analysis of regional entrepreneurship and economic quality development based on system dynamics was conducted to explore the changes in regional entrepreneurship and economic quality development over time and their sensitivity factors. In this way, the dynamic evolution mechanism of the system can be portrayed, and the optimization of the system can be achieved through the coordination of the factors within the system. The article sets up three scenarios to explore the fluctuations in regional entrepreneurship and economic quality development when three sensitive factors, namely, business environment, financial services scale, and innovation environment, change. Findings: There are differences in the development of cities within city clusters. The business environment and high-quality economic development of the central cities within the city cluster are stronger than those of the non-central cities. Therefore, regions should focus on synergistic development within city clusters when formulating related policies. The variation of regional entrepreneurship development and economic quality development, after a factor in the system is changed, is asymmetric. Because the sensitivity of different urban clusters and the way they are affected by sensitive factors varies, the state should pay more attention to the adaptability of cities when formulating corresponding policy measures and adapt its policy measures to the sensitivity characteristics of each region according to local conditions.

Abstract ：
The evolution of financial structure is not only a persistent issue but also a key factor affecting the financial risk. Concerns over the financial structure evolution and risk prevention have been voiced, but studies documented the interaction between financial risk and financial structure are still in their infancy. Therefore, this study investigates it by using detrended cross-correlation analysis, its multifractal asymmetric version, and detrended cross-correlation based on time-delay. Empirical research finds that the market-based financial structure increases financial risk in China. The characteristics of financial risk and financial structure are asymmetry, multifractal, bidirectional transmission, and nonlinear causality. The financial structure's influence on financial risk is strengthened within 15 months, while financial risk's influence on the financial structure strengths within 7 months. These findings support financial supervisory authorities to seek effective strategies to facilitate the evolution of the financial structure and establish a more stable financial system.(c) 2022 Elsevier B.V.

Abstract ：
Purpose Steered by upper echelon theory, this study aims to scrutinize the prevalence of project manager demographic factors (age, education and experience) in project sustainability management and project performance. Design/methodology/approach We used a sample of 209 project managers/supervisor/team leaders who were working in the projects of the China-Pakistan Economic Corridor (CPEC). Findings The results indicate that project manager demographic factors have a significant influence on project performance (except experience) and project sustainability management. Moreover, project sustainability management partially mediates the relationship between age, education and project performance while it fully mediates the path between experience and project performance. Practical implications The research recommends senior, high educated and experienced managers for CPEC who promote sustainability and gain high project performance. Originality/value A number of studies have been carried out to assess the relationship between top managers' attributes and environmental activities. However, so far, none of the studies has paid attention to the CPEC and projects working in Pakistan.

Abstract ：
Improvement of high-temperature mechanical properties of W-Cu based composites is highly desirable but still a challenge. Here it is achieved by combined effects of solid solution, dispersed nano-precipitation and highly stabilized nanostructure in the W-Cu-Cr-ZrC composite, which takes advantage of the in-situ precipitated Zr-Cr-C nanoparticles and phase-separated Cr thin films. The grain size of W phase in the W-Cu-Cr-ZrC composite retained at the nanoscale up to 1000 degrees C (close to Cu melting point) for a long duration. The high thermal stability of the nanostructure endows the composite with a compressive strength of 1150 MPa at 900 degrees C, which is approximately four times as high as that of the binary coarse-grained W-Cu composite. The effects of microstructure evolution on the mechanical properties at high temperatures and its mechanisms were disclosed. The results indicated the crucial role of the microstructural stability of W phase skeleton in the overall strength of the W-Cu based composites.

Abstract ：
In this study, based on the National Centers for Environmental Prediction (NCEP) Final Analysis (FNL) data, the reliability and performances of their application on clean days and polluted days (based on the PM2.5 mass concentrations) in Beijing were assessed. Conventional meteorological factors and diagnostic physical quantities from the NCEP/FNL data were compared with the L-band radar observations in Beijing in the autumns and winters of 2017-2019. The results indicate that the prediction reliability of the temperature was the best compared with those of the relative humidity and wind speed. It is worth noting that the relative humidity was lower and the near-surface wind speed was higher on polluted days from the NCEP/FNL data than from the observations. As far as diagnostic physical quantity is concerned, it was revealed that the temperature inversion intensity depicted by the NCEP/FNL data was significantly lower than that from the observations, especially on polluted days. For example, the difference in the temperature inversion intensity between the NCEP/FNL data and the observation ranged from -0.56 to -0.77 degrees C on polluted days. In addition, the difference in the wind shears between the NCEP/FNL reanalysis data and the observations increased to 0.40 m/s in the lower boundary layer on polluted days compared with that on clean days. Therefore, it is suggested that the underestimation of the relative humidity and temperature inversion intensity, and the overestimation of the near-surface wind speed should be seriously considered in simulating the air quality in the model, particularly on polluted days, which should be focused on more in future model developments.
