The paper utilized a standardized methodology to identify prognostic biomarkers in hepatocellular carcinoma(HCC)by analyzing transcriptomic and clinical data from The Cancer Genome Atlas(TCGA)database.The approach,which included stringent data preprocessing,differential gene expression analysis,and Kaplan-Meier survival analysis,provided valuable insights into the genetic underpinnings of HCC.The comprehensive analysis of a dataset involving 370 HCC patients uncovered correlations between survival status and pathological characteristics,including tumor size,lymph node involvement,and distant metastasis.The processed transcriptome dataset,comprising 420 samples and annotating 26,783 genes,served as a robust platform for identifying differential gene expression patterns.Among the significant differential expression genes,the key genes such as FBXO43,HAGLROS,CRISPLD1,LRRC3.DT,and ERN2,were pinpointed,which showed significant associations with patient survival outcomes,indicating their potential as novel prognostic biomarkers.This study can not only enhance the understanding of HCC’s genetic landscape but also establish a blueprint for a standardized process to discover prognostic biomarkers of various diseases using genetic big data.Future research should focus on validating these biomarkers through independent cohorts and exploring their utility in the development of personalized treatment strategies. 展开更多

Forest biomass resources are available in enormous quantities in China. The development of forest biomass briquetting densification fuel, which has a high calorific value, can ease the energy shortage in China. But the molding technology is still at the primary stage with many questions unresolved, such as unequal distribution of resources, imperfect technology and an inadequate mechanism of market supply and demand. There are no consistent production and quality standards to refer to, which seriously hinder the industrialization of biomass molding technology. Hence, it is imperative to speed up the formulation of production standards of biomass briquetting densification fuel which not only conform to international standards, but are in accordance with national condi- tions in China. Drawing on the standards of biomass briquetting densification fuel in Europe, a standard system should be concerned with raw material collection, transport and storage of the end products, terminology, denomination and classification of molding equipment, as well as with technical conditions, testing methods, safety and environmental protection. The establishment of a stan- dard system is useful for the development of a healthy, orderly and sustainable biomass fuel industry. 展开更多

Objective: to effectively improve the standardized emergency care procedures for patients with ST-segment elevation myocardial infarction. Methods: Seventy-two patients with ST segment elevation myocardial infarction who were admitted to our hospital from January 2020 to December 2020 were selected as the main subjects of this study. They were divided into the control group/observation group. Among them, the control group received routine emergency care while the observation group received standardized emergency care procedures based on the routine emergency care measures, so as to compare the differences in the care procedures and patient care quality of the two patients during the emergency treatment. The difference was large, and the condition of the observation group was better. Finally, through the analysis of two groups of patients after treatment, and then investigate the family members and patients' satisfaction with care. The clinical results showed that the efficacy of 88.9% in the observation group was significantly superior to 66.7% in the control group, and the difference was statistically significant (P < 0.05). Conclusion: through analyzing the different nursing procedures of patients in two groups, it was found that the standardized emergency nursing procedures shortened the basic treatment time of patients and improved the success rate of rescue, providing a larger space for the treatment of patients, and the families were also satisfied with it. 展开更多

Complex industrial process often contains multiple operating modes, and the challenge of multimode process monitoring has recently gained much attention. However, most multivariate statistical process monitoring (MSPM) methods are based on the assumption that the process has only one nominal mode. When the process data contain different distributions, they may not function as well as in single mode processes. To address this issue, an improved partial least squares (IPLS) method was proposed for multimode process monitoring. By utilizing a novel local standardization strategy, the normal data in multiple modes could be centralized after being standardized and the fundamental assumption of partial least squares (PLS) could be valid again in multimode process. In this way, PLS method was extended to be suitable for not only single mode processes but also multimode processes. The efficiency of the proposed method was illustrated by comparing the monitoring results of PLS and IPLS in Tennessee Eastman(TE) process. 展开更多

Ambient air quality standards are the core strategic goal of ambient air quality management.Countries worldwide have given importance to research on the development of ambient air quality standards.To understand the history of the development of China’s ambient air quality standards,this study analyzed the background associated with all previous formulations and revisions of the standards,classification of functional areas,standard grading,pollutants,and evolution of the standard limits over the past 40 years.The results show that since the initial release of the“Ambient Air Quality Standard”by China in 1982,it has been supplemented once,revised twice,and modified twice.The first ambient air quality standard specified the standard limits of six pollutants commonly found in ambient air.With the development of ambient air quality management,the number of pollutants has increased to ten.Since the release of the“Ambient Air Quality Standards”in 2012,the ambient air quality in China has significantly improved.However,the proportion of cities meeting these standards is still low.At present,China is suitably positioned to make the standards associated with 24 hr SO2concentrations more stringent such that it meets the values defined in the World Health Organization(WHO)interim target-2 and the WHO air quality guideline(AQG).We further suggested that the SO2standard should be revised promptly.Simultaneously,regions with a relatively high proportion of cities meeting the standard are encouraged to introduce more stringent interim target limits in due course to manage the local ambient air quality. 展开更多

A new standard parametric modeling method of the micro-structure of plain woven composite is proposed. It is based on good analysis of the mechanical property of the yarn, weaving law of plain woven, and other factors. The method implements a woven fabric composite visual engineering modeling process standardization, and it gives five steps to calculate the key micro-structural parameters of the yarn including the cross-section and the trajectory of the central Line. On the basis, the digital model of a plain woven composite has been constructed. The experimental result shows that the forecast for the mechanical property of the model using finite-element simulation analysis is consistent with the actual value. The shape and the structure of the model are also consistent with the solid. 展开更多
