| 1 | Sparse discriminant analysis for breast cancer biomarker identification and classification显示文摘Biomarker identification and cancer classification are two important procedures in microarray data analysis.We propose a novel unified method to carry out both tasks.We first preselect biomarker candidates by eliminating unrelated genes through the BSS/WSS ratio filter to reduce computational cost,and then use a sparse discriminant analysis method for simultaneous biomarker identification and cancer classification.Moreover,we give a mathematical justification about automatic biomarker identification.Experimental results show that the proposed method can identify key genes that have been verified in biochemical or biomedical research and classify the breast cancer type correctly. | Yu Shi Daoqing Dai Chaochun Liu Hong Yan | 2009 | Progress in Natural Science:Materials International2009，19，11： | 4 |

| 12 | Status and development of the comprehensive utilization of the steel slag at Baosteel显示文摘The steel slag at Baosteel mainly comes from basic oxygen furnaces(BOF),electric arc furnaces(EAF),continuous casting and hot metal pretreatment.The output of the steel slag at Baosteel was 4.43 Mt in 2010.The steel slag was utilized both within the company and across the society,and the utilization rate within the company achieved was 16%.This study describes the current status and existing problems in those technologies of treating and using steel slag,in the aspects of primary treatment,secondary treatment and advanced treatment,and it points out the development's direction. | LIU Jianping GUO Daoqing ZHU Juanyue CHEN Xiaofeng | 2011 | Baosteel Technical Research2011，5，2： | 0 |
| 13 | Development and applications of Baosteel sintering flue gas desulphurization technology显示文摘The research background and technical features of Baosteel sintering flue gas desulphurization(FGD)—swirl-jet-absorbing wet limestone-gypsum sintering FGD technology,process and equipment are introduced in this paper.Main contents and achievements of the pilot experiment and the engineering practice of Baosteel FGD are analyzed and discussed systematically.Past engineering practice experiences indicate that Baosteel FGD has the following merits:wide applicability to sintering flue gas features,such as frequently changing temperatures,unstable SO2 concentration,intensively fluctuating flow rates,etc.,high pollutants removal efficiency,low investment and energy consumption;stable and reliable operation,utilizable byproduct(gypsum),etc.It indicates that Baosteel sintering FGD is of extensive application value for the FGD of large and medium-scaled sintering machines. | SHEN Xiaolin LIU Daoqing LIN Yu SHI Lei WANG Ruyi | 2010 | Baosteel Technical Research2010，4，2： | 0 |
| 14 | Biomineralized nanoparticles for the immobilization and degradation of crude oil-contaminated soil显示文摘Accidental oil leaks and spills often cause server soil pollution,and in situ remediation is a powerful and economical treatment technology.While during in situ remediation process,unpredicted migration of petroleum hydrocarbon in heterogeneous soil will lead to a long-term source of persistent aquifer contamination.To reduce the migration of petroleum hydrocarbon and effectively improve the in situ remediation efficiency,herein,fungal biomineralization strategy was proposed for the immobilization of petroleum contaminants.A ureolytic fungi strain with crude oil-degradation ability was screened and identified as Chaetomium globosum.When incubated in medium containing Ca2+and crude oil,a mineral corona with spiny nanoparticles was formed at the edge of oil and the interface characters were analyzed using fluorescent pH and dissolved oxygen(DO)sensing films,respectively.Results indicated that biominerals preferred to aggregate around the edge of crude oil,providing favorable microenvironment for fungal growth and then leading to the increase of pH in the microenvironment,eventually accompanied by the formation of mineral corona.The mineral corona with numerous nanoparticles may act as a solid and stable shell,limiting or reducing the mobility of crude oil,and providing enough time for fungal biodegradation.After 28 days incubation,oilcontaminated soil treated with fungal biomineralization showed better immobilization ability for total petroleum hydrocarbon(TPH)under simulated acid-rain condition and higher TPH removal efficiency.This is the first demonstration for the immobilization of oil through fungal biomineralized nanoparticles,thus providing a novel strategy for the in situ remediation of oilcontaminated sites. | Daoqing Liu Qianwei Li Enhui Liu Miao Zhang Jicheng Liu Chunmao Chen | 2023 | Nano Research2023，16，10： | 0 |
| 15 | Study on influencing factors of Baosteel’s swirl-jet sintering FGD technology显示文摘This paper introduced the research background and technical features of Baosteel's sintering flue gas desulfurization (FGD).It was also named swirl-jet-absorbing wet limestone-gypsum sintering FGD technology.By means of industrial online pilot plants,through continuous running and orthogonal tests,the effects of various influencing factors on SO2 removal efficiency of Baosteel sintering flue gas desulgurization (BSFGD) were studied carefully.The results indicate that the slurry pH value,temperature (T) and flow rate (Q) of inlet flue gas,liquid level (H) in the absorber and flue gas jet velocity (V) are the main influencing factors.Furthermore,when pH is between 5.0 and 5.5,H is between 4.2 m and 4.3 m,Q is 43 000 m3/h,T is below 65℃ and V is between 20 m/s and 28 m/s,the best desulfurization efficiency can be available. | LIU Daoqing SHEN Xiaolin SHI Lei | 2013 | Baosteel Technical Research2013，7，1： | 0 |
