| 1 | Adaptive Spectr um Decision Method for Heterogeneous Cognitive Radio Networks显示文摘To improve spectrum utilization and minimize interference to Primary User (PU), an adaptive spectrum decision method is proposed for Secondary User (SU), while taking traffic load balancing and spectrum heterogeneity into consideration. Long-term statistics and current sensing results are integrated into the proposed decision method of spectrum access. Two decision methods, namely probability based and sensing based, are presented, compared and followed by performance analysis in terms of delay. For probability based spectrum decision, Short-Time-Job-First (STJF) priority queuing discipline is employed to minimize average residual time and theoretical conclusion is derived in a novel way. For sensing based decision we treat the interrupted service of SU as newly incoming and re-decision process is initialized to find available spectrum in a First-Available-First-Access (FAFA) fashion. Effect of sensing error in PHY layer is also analyzed in terms of extended average residual time. Simulation results show that, for relatively low arriving rate of SU traffic, the proposed spectrum decision method yields at least a delay reduction of 39.5% compared with non-adaptive method. The proposed spectrum decision can significantly improve delay performance even facing sensing errors, which cause performance degeneration to both PU and SU. | Sun Wujian Liu Yang Li Na Li Ou Li Caiping | 2012 | China Communications2012，9，11： | 4 |

| 3 | Preliminary Study on Control Effects of Five Kinds of Fungicides against Wheat Scab显示文摘[Objective] This paper was to improve the current status that the fungicide carbendazim as the single agent was largely applied in the control against wheat scab. [Method] Five kinds of fungicides on sales and new agents against wheat scab were selected for field trials. [Result] 25% JS399-19 SC,30% tebuconazole·thiram WP,75% trifloxystrobin·tebuconazole WDG and 10% ZJ0712 JG could effectively control wheat scab,and the control effects of one time or two times application were better than control agent carbendazim; the control efficacy of two times application was improved in different degrees against one time application. [Conclusion] The paper provided basis for the control against wheat scab. | Chen Wujian Ye Xiufen Zhang Changjie Hu Yufeng Wu Jianguo Chai Rongyao Zhang Zhen | 2013 | Plant Diseases and Pests2013，4，3： | 1 |

| 13 | Single mode rate equations for two sections self—pulsating DFB laser显示文摘We Propose a set of single mode rate equations for multi-section distributed feedback(DFB) lasers. On the basis of the rate equations, the self-pulsation in the two-section DFB lasers with asymmetrical injection current was explained. It was found that the dynamic distribution of the power in two sections play key role in the self-pulsation running. | WangChun-Lin WuJian LinJin-Tong | 2003 | Chinese Physics B2003，12，5： | 1 |

| 15 | Advances in studies on concrete durability and countermeasures against freezing-thawing effects显示文摘This paper is a meta-analysis of recent domestic and foreign research on freezing-thawing effects on concrete durability. The main theories on the mechanisms of freeze-thaw damage to concrete are introduced: the hydrostatic pressure theory, the osmotic pressure theory, the critical water saturation degree theory, the dual mechanism theory, and the micro-ice-crystal lens model theory. The influence laws of freezing-thawing on the mechanical properties of concrete are summarized, and countermeasures to improve concrete durability in freezing-thawing circumstances are presented. This work provides valuable references for future engineering constructions in cold regions. | WuJian Yan FuJun Niu XianJun Zhang Jing Luo GuoAn Yin | 2014 | Research in Cold and Arid Regions2014，6，4： | 1 |
| 16 | A Novel Optical Code Division Multiple Access Ring Network System for LAN显示文摘In this paper the impact factors on the optical fiber LAN network with ring topology are considered. The couple ratio, the self-ring effect, the Multiple-Access Interference (MAI), and the channel noises are the main factors degrading the system performance. We develop a systematic method that employs the smallest p multiplication method to analyze the optimization of the ring network. The results show that choosing an optimal couple ratio and power control will enhance the system performance dramatically. In addition, the “self-ring” interference and MAI can be suppressed by power control to some extent. | WANGYu-Bao GAOYi-Ran MAWen-hua WUJian LINJin-Tong | 2004 | The Journal of China Universities of Posts and Telecommunications2004，11，3： | 1 |

| 20 | Single-base resolution mapping of 2′-O-methylation sites by an exoribonuclease-enriched chemical method显示文摘2′-O-methylation(Nm)is one of the most abundant RNA epigenetic modifications and plays a vital role in the post-transcriptional regulation of gene expression.Current Nm mapping approaches are normally limited to highly abundant RNAs and have significant technical hurdles in m RNAs or relatively rare non-coding RNAs(nc RNAs).Here,we developed a new method for enriching Nm sites by using RNA exoribonuclease and periodate oxidation reactivity to eliminate 2′-hydroxylated(2′-OH)nucleosides,coupled with sequencing(Nm-REP-seq).We revealed several novel classes of Nm-containing nc RNAs as well as m RNAs in humans,mice,and drosophila.We found that some novel Nm sites are present at fixed positions in different t RNAs and are potential substrates of fibrillarin(FBL)methyltransferase mediated by sno RNAs.Importantly,we discovered,for the first time,that Nm located at the 3′-end of various types of nc RNAs and fragments derived from them.Our approach precisely redefines the genome-wide distribution of Nm and provides new technologies for functional studies of Nm-mediated gene regulation. | Ping Zhang Junhong Huang Wujian Zheng Lifan Chen Shurong Liu Anrui Liu Jiayi Ye Jie Zhou Zhirong Chen Qiaojuan Huang Shun Liu Keren Zhou Lianghu Qu Bin Li Jianhua Yang | 2023 | Science China(Life Sciences)2023，66，4： | 0 |
