SIDMAP:A Service-oriented Mapping System for Loc/ID split Internet Naming
Daochao Huang,Dong Yang,Fei Song,Hongke Zhang
Journal of Communications , 2011, DOI: 10.4304/jcm.6.8.601-609
Abstract: While locator/identifier split makes Internet routing more scalable, the promise of a mapping system that resolves a service to corresponding location is yet to be realized. Part of the challenge is due to most current approaches only focusing on how to find the location of a host, not the location of a service, which make these systems rely on extra naming system to provide applications the requested service's location and introduce complex load interactions between the locator/identifier mapping system and naming system. Another challenge is due to the vast majority of current Internet usage changed from host-centric applications to data retrieval and service access, traditional domain name system (DNS) is unable to support today's Internet needs such as service migration and composition. We introduce SIDMAP--a novel,efficient service-oriented naming scheme for incorporating service identifier/identifier mapping system that returns appropriate locators in response to mapping requests for specific service identifiers,service migration and service composition into one system. According to the result of evaluations, our mechanism has good scalability and low resolution latency.

PLOS ONE , 2012, DOI: 10.1371/journal.pone.0047013
Abstract: Background Obesity is a risk factor for the development of certain respiratory diseases, and neonatal overfeeding results in an early onset of obesity in adulthood. However, the influence of neonatal overfeeding on respiratory diseases has rarely been studied. Therefore, this paper is aimed at investigating the effect of neonatal overfeeding on airway responsiveness and inflammation. Methodology/Principal Findings The neonatal overfeeding was induced by reducing litter size to three pups per litter (small litter, SL) in contrast to the normal litter size with ten pups per litter (NL) on postnatal day 3 (P3) in male ICR mice. On P21, mice were weaned to standard chow diet. Airway responsiveness to methacholine was measured either on P21 or P150. Total and classified inflammatory cells in bronchoalveolar lavage fluid (BALF) were counted, lung inflammatory cells were evaluated through staining with hematoxylin & eosin and F4/80 immunohistochemistry; lung fibrosis was evaluated through staining with Masson and α-SAM immunohistochemistry. Leptin levels in serum were measured by RIA; TNF-α levels in serum and BALF were quantified by ELISA; mRNA levels of TNF-α, CTGF and TGF-β1 in lung tissues were measured using real-time PCR. Mice from SL exhibited accelerated body weight gain, impaired glucose tolerance and hyperleptinemia. Enhanced airway responsiveness to methacholine was observed in SL mice on P150, but not on P21. Pulmonary inflammation was evident in SL mice on P150, as reflected by inflammatory cells especially macrophages around bronchi and interstitium. BALF and serum TNF-α levels and lung TNF-α mRNA expression were significantly increased in SL mice on P150. More collagen accumulated surrounding the bronchi on P150; lung mRNA levels of TGF-β1 and CTGF were also increased on P150. Conclusion In addition to inducing a variety of metabolic defects, neonatal overfeeding enhanced lung inflammation, which may lead to airway remodeling and airway hyperresponsiveness in adulthood.

Abstract: 为明确河南省小麦纹枯病病原组成及对三唑酮的敏感性,采用番红O-KOH染色并结合培养性状观察,对2016年分离自河南省18个县(区、市)的132株菌株进行了鉴定,采用菌丝生长速率法测定了病菌对三唑酮的敏感性,并比较了同一地块不同年份采集菌株对药剂的敏感性变化。结果表明:132株菌株全部为禾谷丝核菌Rhizoctonia cerealis。病菌对三唑酮的EC50在0.69~8.32 μg/mL之间,EC50平均值为2.66 μg/mL;敏感性频率分布图显示,病菌群体中已出现对三唑酮敏感性下降的亚群体,可将其中呈连续单峰频次分布的大多数菌株EC50的平均值2.21 μg/mL作为2016年小麦纹枯病菌对三唑酮的相对敏感基线。同一县(区、市)的菌株对三唑酮的敏感性差异较大,EC50最大值与最小值比在1.21~10.27倍之间;而不同县(区、市)的菌株对三唑酮的敏感性差异不明显,EC50平均值变化范围在1.34~4.68 μg/mL之间,相差3.50倍。采自同一地块的菌株,2016年的菌株对药剂的敏感性相较于2015年有所降低,2016年的菌株对三唑酮的敏感基线是2015年的1.77倍。研究表明,尽管三唑酮依然可以用于小麦纹枯病的综合防控,但生产中应持续监测小麦纹枯病菌对药剂敏感性的动态变化。
In order to identify the pathogen composition of wheat sharp eyespot from Henan Province and detect the sensitivity of pathogenic fungi to triadimefon, 132 isolates were collected from 18 counties in 2016. All of the isolates belonged to Rhizoctonia cerealis based on safranine nuclear staining and culture characteristics grown on PSA medium. Their sensitivity to triadimefon was determined in vitro by mycelial growth rate method. The results showed that 50% effective concentration (EC50) of all isolates to triadimefon ranged from 0.69 μg/mL to 8.32 μg/mL, and the average value was 2.66 μg/mL. The results of the frequency analysis showed that the subpopulation that was less sensitive to triadimefon had been discovered in the tested isolates. The mean EC50 of 2.21 μg/mL for most isolates showed a unimodal curve distribution, which was treated as the sensitive baseline of R. cerealis to triadimefon. The results of both variance analysis by LSD test and hierarchical cluster analysis by SPSS indicated that the isolates separated from the same region demonstrated different sensitivities, which implied that the ratio of maximum and minimum EC50 of the isolates from the same region ranged from 1.21 to 10.27. However, there was no significant difference in the sensitivity to triadimefon among the isolates from most of the regions, showing that the average EC50 of the isolates from all the regions ranged from 1.34 μg/mL to 4.68 μg/mL and the ratio of maximum and minimum average EC50 was 3.50. The isolates collected in 2016 was less sensitive to triadimefon than those in 2015 from the same field. The sensitive baseline to triadimefon of the isolates collected in 2016 was 1.77 times that in 2015, which implied that its sensitivity to triadimefon in Henan Province should be monitored continuously.

Abstract: 为探究噻虫嗪对白背飞虱的亚致死效应,采用稻茎浸渍法以噻虫嗪亚致死浓度LC10和LC25胁迫白背飞虱3龄若虫,测定了F0代和F1代若虫的存活率、雌成虫寿命和产卵量,并组建了F1代种群相对适合度生命表。结果表明,经噻虫嗪亚致死浓度胁迫后,F0代白背飞虱若虫的发育历期延长,存活率降低,并且LC10处理组的F0代雌成虫寿命比对照组显著延长,而成虫产卵量显著变化;F1代的若虫发育历期比对照组显著延长,且产卵量有所减少,LC10处理组雌成虫产卵量比对照组减少了22.24,LC25处理组比对照组减少了69.96,且差异显著;LC10和LC25亚致死浓度处理后F1代的种群增长趋势指数均下降,种群相对适合度分别下降了0.12和0.36。研究表明,噻虫嗪亚致死浓度胁迫均可抑制白背飞虱的种群增长。
To figure out the sublethal effects of thiamethoxam on white-backed planthopper Sogatella furcifera(Horváth),the 3rd instar nymphs were exposed to the two sublethal doses LC10 and LC25 of thiamethoxam with the rice stem dipping method.The survival rates of F0 and F1 nymphs,the longevity and fecundity of F0 and F1 adults were investigated.The life-table of F1 generation was constructed.The results showed that both sublethal doses could prolong the developmental duration and decrease the survival rate of F0 nymphs.In addition,F0 female adults treated by LC10 of thiamethoxam had significant longer lifespan compared to that of the control,and the fecundity of adults had no difference from that of the control.As for F1 generation,both treatments significantly prolonged the developmental durations of nymphs.The oviposition amount of adults treated with LC10 of thiamethoxam was 22.24 eggs less than that of the control,while that of the adults treated with LC25 of thiamethoxam was significantly 69.96 eggs less than that of the control.Both sublethal doses of thiamethoxam resulted in declining population trend index.The relative fitness of F1 generation treated by LC10 and LC25 of thiamethoxam was reduced by 0.12 and 0.36,respectively.The results indicated that the sublethal dose of thiamethoxam had negative effect on S.furcifera.

A Real-Time Transient Analysis of a Functionally Graded Material Plate Using Reduced-Basis Methods  [PDF]
Yonghui Huang, Yi Huang
Advances in Linear Algebra & Matrix Theory (ALAMT) , 2015, DOI: 10.4236/alamt.2015.53010
Abstract: Based on the hybrid numerical method (HNM) combining with a reduced-basis method (RBM), the real-time transient response of a functionally graded material (FGM) plates is obtained. The large eigenvalue problem in wavenumber domain has been solved through real-time off-line/on-line calculation. At off-line stage, a reduced-basis space is constructed in sample wavenumbers according to the solved eigenvalue problems. The matrices independent of parameters are projected onto the reduced-basis spaces. At on-line stage, the reduced eigenvalue problems of the arbitrary wavenumbers are built. Subsequently, the responses in wavenumber domain are obtained by the approximated eigen-pairs. Because of the application of RBM, the computational cost of transient displacement analysis of FGM plate is decreased significantly, while the accuracy of the solution and the physics of the structure are still retained. The efficiency and validity of the proposed method are demonstrated through a numerical example.
