| 2 | Personalized Recommendation Algorithm Based on Preference Features显示文摘A hybrid collaborative filtering algorithm based on the user preferences and item features is proposed. A thorough investigation of Collaborative Filtering(CF) techniques preceded the development of this algorithm. The proposed algorithm improved the user-item similarity approach by extracting the item feature and applying various item features' weight to the item to confirm different item features. User preferences for different item features were obtained by employing user evaluations of the items. It is expected that providing better recommendations according to preferences and features would improve the accuracy and efficiency of recommendations and also make it easier to deal with the data sparsity. In addition, it is expected that the potential semantics of the user evaluation model would be revealed. This would explain the recommendation results and increase accuracy. A portion of the MovieLens database was used to conduct a comparative experiment among the proposed algorithms,i.e., the collaborative filtering algorithm based on the item and the collaborative filtering algorithm based on the item feature. The Mean Absolute Error(MAE) was utilized to conduct performance testing. The experimental results show that employing the proposed personalized recommendation algorithm based on the preference-feature would significantly improve the accuracy of evaluation predictions compared to two previous approaches. | Liang Hu Guohang Song Zhenzhen Xie Kuo Zhao | 2014 | Tsinghua Science and Technology2014,19,3: | 8 |

| 4 | Effect of Multiple Coatings of One-step Self-etching Adhesive on Microtensile Bond Strength to Primary Dentin显示文摘Objective To investigate the effect of multiple coatings of the one-step self-etching adhesive on immediate microtensile bond strength to primary dentin.Methods Twelve caries-free human primary molars were randomly divided into 2 groups with 6 teeth each.In group 1,each tooth was hemisected into two halves.One half was assigned to control subgroup 1,which was bonded with a single-step self-etching adhesive according to the manufacturer's instructions;the other half was assigned to experimental subgroup 1 in which the adhesive was applied three times before light curing.In group 2,the teeth were also hemisected into two halves.One half was assigned to control subgroup 2,which was bonded with the single-step self-etching adhesive according to the manufacturer's instructions;the other half was assigned to experimental subgroup 2 in which three layers of adhesive were applied with light curing each successive layer.Microtensile bond strength was immediately tested after specimen preparation.Results When the adhesive was applied three times before light curing,the bond strength of the experimental subgroup 1(n=33,57.49±11.61 MPa) was higher than that of the control subgroup 1(n=31,49.71±11.43 MPa,P<0.05).When using the technique of applying multiple layers of adhesive with light curing each successive layer,no difference of immediate bond strength was observed between the control subgroup 2 and the experimental subgroup 2(P>0.05).Conclusion Multiple coatings of one-step self-etching adhesive can increase the immediate bond strength to primary dentin when using the technique of light-curing after applying three layers of adhesive. | Lin Ma Jian-feng Zhou Jian-guo Tan Quan Jing Ji-zhi Zhao Kuo Wan | 2011 | Chinese Medical Sciences Journal2011,26,3: | 4 |
| 5 | Probing primordial gravitational waves: Ali CMB Polarization Telescope显示文摘In this paper, we will give a general introduction to the Ali CMB Polarization Telescope(Ali CPT) project,which is a Sino–US joint project led by the Institute of High Energy Physics and involves many different institutes in China. It is the first ground-based Cosmic Microwave Background(CMB) polarization experiment in China and an integral part of China's Gravitational-wave Program. The main scientific goal of the Ali CPT project is to probe the primordial gravitational waves(PGWs) originating from the very early Universe. The AliCPT project includes two stages. The first stage, referred to as AliCPT-1, is to build a telescope in the Ali region of Tibet at an altitude of 5250 meters. Once completed, it will be the highest ground-based CMB observatory in the world and will open a new window for probing PGWs in the northern hemisphere. The AliCPT-1 telescope is designed to have about 7000 transition-edge sensor detectors at 95 GHz and 150 GHz. The second stage is to have a more sensitive telescope(Ali CPT-2) with more than 20 000 detectors. Our simulations show that AliCPT will improve the current constraint on the tensor-to-scalar ratio r by one order of magnitude with three years' observation. Besides the PGWs, Ali CPT will also enable a precise measurement of the CMB rotation angle and provide a precise test of the CPT symmetry. We show that three years' observation will improve the current limit by two orders of magnitude. | Hong Li Si-Yu Li Yang Liu Yong-Ping Li Yifu Cai Mingzhe Li Gong-Bo Zhao Cong-Zhan Liu Zheng-Wei Li He Xu Di Wu Yong-Jie Zhang Zu-Hui Fan Yong-Qiang Yao Chao-Lin Kuo Fang-Jun Lu Xinmin Zhang | 2019 | National Science Review2019,6,1: | 4 |
| 6 | SCC evaluation of a 2297 Al-Li alloy rolled plate using the slow-strain rate technique显示文摘The stress corrosion cracking(SCC) susceptibility of 2297 Al-Li alloy in 1 M Na Cl +0.01 M H2O2 solution(CP solution) and 1 M NaCl + 0.01 M H2O2+ 0.6 M Na2SO4 solution(CPS solution) was investigated by slow-strain rate tests at various strain rates ranging from 10-5s(-1) to 10-7s-1. The roles of H2O2 and SO42-in the corrosion process were estimated by potentiodynamic polarization and electrochemical impedance spectroscopy. 2297 Al-Li alloy does not fracture ascribed to SCC in CP solution, while it undergoes SCC in CPS solution. In CPS solution,with a decreasing strain rate from 10-5s(-1) to 10-7s-1, the SCC susceptibility firstly rises and then declines exhibiting a peak value at a strain rate of 10-6s-1. H2O2 promotes the active dissolution while SO42- lowers the corrosion rate. The SCC fracture is associated with a decline in the dissolution rate of the crack tip by SO42-, which leads to stress concentration. In CPS solution, a reduction in the local dissolution rate of the crack tip leads to stress concentration, resulting in SCC fracture.As the preferred initiation site for a crack, pits also show a noteworthy effect on SCC of 2297 Al-Li alloy. | Kuo ZHAO Jianhua LIU Mei YU Songmei LI | 2019 | Chinese Journal of Aeronautics2019,32,11: | 3 |

| 9 | Overexpression of miR-101 suppresses collagen synthesis by targeting EZH2 in hypertrophic scar fibroblasts显示文摘Background:MicroRNA-101(miR-101)is a tumor suppressor microRNA(miRNA)and its loss is associated with the occurrence and progression of various diseases.However,the biological function and target of miR-101 in the pathogenesis of hypertrophic scars(HS)remains unknown.Methods:We harvested HS and paired normal skin(NS)tissue samples from patients and cultured their fibroblasts(HSF and NSF,respectively).We used quantitative reverse transcriptase polymerase chain reaction(qRT-PCR),fluorescence in situ hybridization(FISH),enzyme-linked immunosorbent assays(ELISA)and Western blot analyses to measure mRNA levels and protein expression of miR-101,enhancer of zeste homolog 2(EZH2),collagen 1 and 3(Col1 and Col3)andα-smooth muscle actin(α-SMA)in different in vitro conditions.We also used RNA sequencing to evaluate the relevant signaling pathways and bioinformatics analysis and dual-luciferase reporter assays to predict miR-101 targets.We utilized a bleomycin-induced fibrosis mouse model in which we injected miR-101 mimics to evaluate collagen deposition in vivo.Results:We found low expression of miR-101 in HS and HSF compared to NS and NSF.Overexpressing miR-101 decreased Col1,Col3 andα-SMA expression in HSF.We detected high expression of EZH2 in HS and HSF.Knockdown of EZH2 decreased Col1,Col3 andα-SMA in HSF.Mechanistically,miR-101 targeted the 3-untranslated region(3UTR)of EZH2,as indicated by the decreased expression of EZH2.Overexpressing EZH2 rescued miR-101-induced collagen repression.MiR-101 mimics effectively suppressed collagen deposition in the bleomycin-induced fibrosis mouse model.Conclusions:Our data reveal that miR-101 targets EZH2 in HS collagen production,providing new insight into the pathological mechanisms underlying HS formation. | Jie Li Yan Li Yunchuan Wang Xiang He Jing Wang Weixia Cai Yanhui Jia Dan Xiao Jian Zhang Ming Zhao Kuo Shen Zichao Li Wenbin Jia Kejia Wang Yue Zhang Linlin Su Huayu Zhu Dahai Hu | 2021 | Burns & Trauma2021,9,1: | 3 |
| 10 | An Efficient Multidimensional Fusion Algorithm for IoT Data Based on Partitioning显示文摘The Internet of Things (IoT) implies a worldwide network of interconnected objects uniquely addressable, via standard communication protocols. The prevalence of IoT is bound to generate large amounts of multisource, heterogeneous, dynamic, and sparse data. However, IoT offers inconsequential practical benefits without the ability to integrate, fuse, and glean useful information from such massive amounts of data. Accordingly, preparing us for the imminent invasion of things, a tool called data fusion can be used to manipulate and manage such data in order to improve process efficiency and provide advanced intelligence. In order to determine an acceptable quality of intelligence, diverse and voluminous data have to be combined and fused. Therefore, it is imperative to improve the computational efficiency for fusing and mining multidimensional data. In this paper, we propose an efficient multidimensional fusion algorithm for IoT data based on partitioning. The basic concept involves the partitioning of dimensions (attributes), i.e., a big data set with higher dimensions can be transformed into certain number of relatively smaller data subsets that can be easily processed. Then, based on the partitioning of dimensions, the discernible matrixes of all data subsets in rough set theory are computed to obtain their core attribute sets. Furthermore, a global core attribute set can be determined. Finally, the attribute reduction and rule extraction methods are used to obtain the fusion results. By means of proving a few theorems and simulation, the correctness and effectiveness of this algorithm is illustrated. | Jin Zhou Liang Hu Feng Wang Huimin Lu Kuo Zhao | 2013 | Tsinghua Science and Technology2013,18,4: | 3 |

| 15 | BLOOD PRESSURE CHANGES OF ELDERLY HYPERTENSIVE PATIENTS DURING DENTAL EXTRACTION UNDER SEDATION WITH CONTINUOUS INTRAVENOUS INFUSION OF MIDAZOLAM显示文摘Objective To evaluate the changes in blood pressure (BP) of elderly hypertensive patients having dental extraction under sedation with continuous intravenous infusion of midazolam. Methods One hundred elderly hypertensive patients undergoing dental extraction were recruited for this single-blind, randomized, controlled study. Patients in intervention group (n=50) were given midazolam dissolved in glucose solution and patients in control group (n=50) were given glucose solution only with communication technique. Systolic BP (SBP) and diastolic BP (DBP) were recorded in five time points. Results Under basal conditions, intervention group did not show significant difference in BP compared with control group. Before sedation, mean values of SBP and DBP (especially SBP) significantly increased compared with basal conditions in both groups (P<0.05). During dental extraction sessions, mean values of BP in intervention group significantly decreased than control group (P<0.05), but coefficient of variation did show significant difference in both groups. Conclusion Continuous intravenous infusion of midazolam has been proved to be very successful in controlling BP of elderly patients having dental extraction. | Ji-zhi Zhao Kuo Wan Quan Jing Xi Chen | 2007 | Chinese Medical Sciences Journal2007,22,2: | 2 |

| 17 | A Novel Routing Method for Social Delay-Tolerant Networks显示文摘The lack of continuous connectivity and a complete path from source to destination makes node communication quite difficult in Delay-Tolerant Networks(DTNs). Most studies focus on routing problems in idealized network environments without considering social properties. Communication devices are carried by individuals in many DTNs; therefore, DTNs are unique social networks to some extent. To design efficient routing protocols for DTNs, it is important to analyze their social properties. In this paper, a more accurate and comprehensive metric for detecting the quality of the relationships between nodes is proposed, by considering the contact time, contact frequency, and contact regularity. An overlapping hierarchical community detection method is designed based on this new metric, and a tree structure is built. Furthermore, we exploit the overlapping community structure and the tree structure to provide message-forwarding paths from the source node to the destination node.The simulation results show that our Routing method based on Overlapping hierarchical Community Detection(ROCD) achieves better delivery rate than SimBet and Bubble Rap, the classic routing protocols, without affecting the average delay. | Xiangyu Meng Gaochao Xu Tingting Guo Yongjian Yang Wenxu Shen Kuo Zhao | 2019 | Tsinghua Science and Technology2019,24,1: | 2 |
| 18 | Plasma metabolomics combined with personalized diagnosis guided by Chinese medicine reveals subtypes of chronic heart failure显示文摘Background:Chronic heart failure(CHF)is characterized by insufficient blood supply from heart to meet the body’s metabolic demands.Integrating Western and traditional Chinese medicine to treat CHF has proved a validated therapeutic approach.In recent years,metabolomics has been regarded as a potential platform to provide biomarkers for diseasesubtypes.Objective:To examine 38 patients,combined NMR plasma metabolomics and traditional Chinese medicine diagnosis in order to identify diagnostic biomarkers for two CHF syndrome subtypes.Methods:After processing the spectra,orthogonal partial least square discriminant analysis was performed,and the contributing NMR signals were analyzed using Y-scrambling statistical validation with good reliability.Results:Plasma metabolic patterns of yin deficiency and yang deficiency patients were clearly discriminated.The yin-deficiency group had increased level of lactate,glycoprotein,lipoprotein and lower levels of glucose,valine and proline.The yang-deficiency group had higher levels of lactate,glycoprotein and pyruvic acid,and lower levels of glucose and lipoprotein.Potential biomarkers of CHF based on the two traditional Chinese medicine syndromes indicated alternative modes of metabolites and metabolic pathways in the disease,e.g.dysfunction of energy utilization and disturbance in fatty acids,amino acids.Conclusion:This study suggests that combining metabolomics with traditional Chinese medicine diagnosis can reveal metabolic signatures for CHF syndrome subtypes.The plasma metabolites identified might be of special clinical relevance for subtypes of CHF,which could lead to further understanding of mechanisms involved and an improvement in personalized treatment for CHF. | Juan Wang Shuzhen Guo Kuo Gao Qi Shi Bangze Fu Chan Chen Liangtao Luo Dong Deng Huihui Zhao Wei Wang | 2015 | Journal of Traditional Chinese Medical Sciences2015,2,2: | 2 |
| 19 | Effects of dry/wet ratio and pre-immersion on stress corrosion cracking of 7050-T7451 aluminum alloy under wet-dry cyclic conditions显示文摘The stress corrosion cracking(SCC) behavior and mechanism of 7050-T7451 aluminum alloy under wet-dry cyclic conditions were investigated. Slow strain rate tests(SSRTs) and electrochemical tests were used to study the effects of dry/wet ratio(DWR) and pre-immersion on SCC.Fracture and side surface characterizations were observed by scanning electron microscopy(SEM).The results demonstrate that SCC susceptibility decreases with an increase of the DWR. With an increase of the pre-immersion time, both continuous pre-immersion(CP) and wet-dry cyclic preimmersion(WDP) samples are more sensitive to SCC, and the cracking mode in the SCC fracture region is intergranular. Furthermore, the effect of WDP on SCC is greater than that of CP when the total time immersed in solution before an SSRT is the same with each other. In fact, each single wetdry cycle can be divided into three processes with respect to the change of solution on samples' surface. Volatilization of water on the surface results in an increase in solute concentration, thus accelerating corrosion. | Mei YU Hang ZU Kuo ZHAO Jianhua LIU Songmei LI | 2018 | Chinese Journal of Aeronautics2018,31,11: | 2 |
| 20 | Optimization of the Deployment of Temperature Nodes Based on Linear Programing in the Internet of Things显示文摘The Internet of Things emphasizes the concept of objects connected with each other, which includes all kinds of wireless sensor networks. An important issue is to reduce the energy consumption in the sensor networks since sensor nodes always have energy constraints. Deployment of thousands of wireless sensors in an appropriate pattern will simultaneously satisfy the application requirements and reduce the sensor network energy consumption. This article deployed a number of sensor nodes to record temperature data. The data was then used to predict the temperatures of some of the sensor node using linear programming. The predictions were able to reduce the node sampling rate and to optimize the node deployment to reduce the sensor energy consumption. This method can compensate for the temporarily disabled nodes. The main objective is to design the objective function and determine the constraint condition for the linear programming. The result based on real experiments shows that this method successfully predicts the values of unknown sensor nodes and optimizes the node deployment. The sensor network energy consumption is also reduced by the optimized node deployment. | Liang Hu Zhengyu Zhang Feng Wang Kuo Zhao | 2013 | Tsinghua Science and Technology2013,18,3: | 2 |
