The purpose of this study is to examine how economic development and stability are affected by carbon trading pilot programs. Using panel data from 31 Chinese provinces and autonomous regions between 2005 and 2021, two hypotheses were tested using the DID model. The findings indicate that (1) the carbon trading market pilot program has an immediate...

Under the background of high-quality development, the e-commerce industry needs to seek more comprehensive development, and the logistics industry should not only maintain higher efficiency, but also meet the requirements of green and low-carbon transportation. This study aims to investigate the link between the logistic density and the proportion...

Development that is eco-friendly, coordinated, sustainable, and of the highest caliber is crucial to China’s modernization. Based on the Cobb–Douglas production function and environmental Kuznets curve analysis, this paper investigates the link between green finance and the reduction of carbon emissions and high-quality economic development, then p...

The Belt and Road Initiative (BRI) is a development plan proposed by China that aims to build a new platform for international cooperation and create new drivers of shared development. South Asia is a key area in the Belt and Road Initiative, including eight countries. As the BRI implemented, China’s trade with South Asia has been gradually strengt...

The Carbon trading price (CTP) can best reflect the fluctuations of the carbon trading market. This paper comprehensively analyzes the CTP mechanism of China’s carbon trading market, discusses the main factors affecting China’s CTP, which include macroeconomic factors, energy price factors, policy factors, and environmental factors, and provides th...

Fasteners are critical components of railways that maintain the rail tracks in a fixed position. Their failure can lead to serious accidents such as train derailments, so their condition needs to be inspected periodically. Conventional image-based inspection methods fail to take full advantage of the structural features of fasteners, making them le...

Phase ranging method of distance measurement usually sacrifices the simplicity of the ranging system by adding complex circuit and multi-frequency ruler to achieve high accuracy. Laser pulse ranging has the counting error of the number of round-trip pulses which affects the accuracy of flight time calculation. Hence a novel method to measure a dist...

A novel method to measure a distance by triangular-wave amplitude modulation laser based on the least squares is proposed. We designed two identical channels of referenced signal and measured signal with optical path difference in this system. Their return signals are fitted by using the improved straight-line fitting algorithm based on the least s...

Despite the progress made in selective plane illumination microscopy, high-resolution 3D live imaging of multicellular specimens remains challenging. Tiling light-sheet selective plane illumination microscopy (TLS-SPIM) with real-time light-sheet optimization was developed to respond to the challenge. It improves the 3D imaging ability of SPIM in r...
