“…DOAS has been widely used in studies of the vertical distribution characteristics of atmospheric components in different environments (suburban, regional, island, and offshore) in different regions, e.g., the Beijing-Tianjin-Hebei [9,[17][18][19], the Pearl River Delta region [13,20,21] and the YRD region [22][23][24][25][26][27]. This technology provides a promising method for the accurate monitoring and management of air pollution.…”

“…The most important advantage of the MAX-DOAS is that it can simultaneously monitor various atmospheric components, including aerosols, NO 2 , and HCHO, thereby overcoming the errors of atmospheric component monitoring using different instruments.

Due to the difference of industrialization degree and meteorological conditions, there are obvious differences in the composition of air pollution between islands and inland areas. With Zhoushan (ZS) and Nanjing (NJ) representing islands and inland cities in the Yangtze River Delta, the differences in vertical distribution of atmospheric components were investigated. A combination of multi-axial differential optical absorption spectroscopy (MAX-DOAS), weather research and forecasting (WRF), and potential source contribution function (PSCF) models were used to obtain vertical distribution data for aerosols, nitrogen dioxide (NO2) and formaldehyde (HCHO), meteorological factors, and pollution sources in summer 2019. The findings indicate that, except for the aerosol extinction coefficient (AE), the atmospheric composition at the ZS site was not significantly stratified. However, the AE, NO2, and HCHO at NJ all displayed a decreasing trend with altitude. Here is the interesting finding that the ZS site has a higher AE value than the NJ site, while NJ displays higher NO2 and HCHO columns than the ZS site. This discrepancy was primarily attributable to Zhoushan City’s extremely low traffic emissions when compared to inland cities. In addition, HCHO in the YRD region was significantly affected by human activities. Analysis of potential pollution sources found that regional transport contributed to differences in atmospheric composition at different altitudes in different regions. Aerosols, NO2, and HCHO in Nanjing were significantly affected by transport in inland areas. Aerosols in Zhoushan were easily affected by transport in the Yellow Sea and East China Sea, and NO2 and HCHO were significantly affected by transport contributions from surrounding areas in inland areas. The study strongly suggests that land and sea breezes play an important role in the vertical distribution of aerosols over island regions.

“…Theoretically, protein-based biological computers can be made by using protein molecules as components. Because protein molecules are not only much smaller than electronic components on silicon chips, but also have low impedance and low energy consumption, they have not only huge storage capacity and the ability to process information at high speed, but also better solve the heat dissipation problem [30]. Proteins are capable of performing complex computations with high accuracy and speed.…”

Moore's Law is a concept that notes the doubling of the number of transistors on a microchip around every two years, resulting in exponential advancement in computing power and diminishing costs. However, as transistor sizes have approached the physical limits of silicon-based technology, maintaining this pace of growth has become increasingly challenging. As a result, researchers have been exploring alternative solutions, such as System-in-package(SiP), Chiplets, Non-volatile memory, Biocomputing, quantum computing, and photonics. While these technologies are still in the early stages of development, they offer promising solutions to the challenges facing the continued growth of computing power. As we continue to explore new avenues for technological advancement, we may find that Moore's Law continues to hold true in unexpected and exciting ways.
