This study aims to examine the policy effects of the “Three-Year Action Plan to Win the Blue Sky War” on the steel industry and air pollution in China. Specifically, we analyze the impact of the “Blue Sky Plan” on Chinese steel companies’ ESG investments, corporate financial performance, and the emissions of sulfur dioxide and nitrogen oxides in the exhaust gas. Our evidence suggests that ESG investment in steel companies can lead to a significant decrease in financial performance. The “Blue Sky Plan” compensated for about one-third of corporate ESG investment losses and played a significant role in promoting the ESG investment of steel companies. In addition, we found that after the implementation of the “Blue Sky Plan,” the emissions of sulfur dioxide and nitrogen oxides in the exhaust gases were significantly reduced.

Prosopis is a regional cash crop that is widely grown in arid, semiarid, tropical, and subtropical areas. Compared with other legume plants, Prosopis is underutilized and has great potentialities. Prosopis not only is a good source of timber, construction, fencing material, and gum, but also can be applied for food, beverage, feed, and medicine. Prosopis contains numerous phytochemical constituents, including carbohydrates, proteins, fatty acids, minerals, and vitamins, while varieties of phenolic compounds have also been identified from different parts of Prosopis. Flavonoids (especially C-glycosyl flavonoids), tannins, catechin, 4′-O-methyl-gallocatechin, mesquitol, and quercetin O-glycosides are significant phenolic contents in Prosopis. Various extracts of Prosopis displayed a wide range of biological properties, such as antioxidant, antihyperglycemic, antibacterial, anthelmintic, antitumor, and anticancer. Additionally, Prosopis has the potential to be an ideal diet that contains abundant dietary fiber, minerals, galactomannans, and low-fat content. However, the bioactivity and pharmacological properties associated with Prosopis were influenced by the bioavailability of phytochemicals, various antinutritional compounds, and the interactions of protein and phenolic compounds. The bioavailability of Prosopis is mainly affected by phenolic contents, especially catechin. The antinutritional compounds negatively affect the nutritional qualities of Prosopis, which can be prevented by heating. The protein-phenolic compound interactions can help the human body to absorb quercetin from Prosopis. This literature review aimed to provide systematic information on the physical, biochemical, pharmacological, and nutritional properties and potential applications of Prosopis.

Execution anomaly detection is important for development, maintenance and performance tuning in large-scale systems. System console logs are the significant source of troubleshooting and problem diagnosis. However, manually inspecting logs to detect anomalies is unfeasible due to the increasing volume and complexity of log files. Therefore, this is a substantial demand for automatic anomaly detection based on log analysis. In this paper, we propose a general method to mine console logs to detect system problems. We first give some formal definitions of the problem, and then extract the set of log statements in the source code and generate the reachability graph to reveal the reachable relations of log statements. After that, we parse the log files to create log messages by combining information about log statements with information retrieval techniques. These messages are grouped into execution traces according to their execution units. We propose a novel anomaly detection algorithm that considers traces as sequence data and uses a probabilistic suffix tree based method to organize and differentiate significant statistical properties possessed by the sequences. Experiments on a CloudStack testbed and a Hadoop production system show that our method can effectively detect running anomalies in comparison with existing four detection algorithms.

The G protein-coupled receptor 30 (GPR30) is a transmembrane estrogen receptor that binds to estrogen, and has been confirmed to have an important role in testicular cell proliferation and development. The main objective of this study was to examine GPR30 gene expression and localization in the testis and epididymis of sheep at different developmental stages. Testes, including the epididymis, were collected from Polled Dorset x Mongolian cross rams at one (n=4; wt), three (n=4; wt), six (n=4; wt), nine (n=4; wt) and 12 (n=4; wt) months of age. The 12-month-old hybrid crossbred sheep were exsanguinated via puncture of the jugular vein. Relative abundance of GPR30 mRNA was detected by quantitative PCR, and localization of the protein was examined by immunohistochemistry. Semi-quantitative analysis of GPR30 protein was performed by western blotting. The relative abundance of GPR30 mRNA was similar in the epididymis tail for rams at 6, 9, and 12mo of age. Further, relative abundance of GPR30 mRNA in the testes and caput epididymis of 1-, 3-, 6-, 9-, and 12-month-old crossbred rams did not increase with age. The GPR30 mRNA was detected in epididymal interstitial and principal cells, and in the epididymal cavity, spermatocytes, spermatogonial stem cells, Sertoli and Leydig cells, and spermatozoon of ram testes. Western blotting indicated the GPR30 protein was present in 9- and 12-month-old crossbred sheep corpus, cauda epididymis (P0.05). The results suggest that relative abundance of GPR30 mRNA is time-dependent and localization-specific.
