| 1 | Analysis on Volatile Constituents in Leaves and Fruits of Ficus carica by GC-MS显示文摘Objective To identify and analyze the volatile constituents in the leaves and fruits of Ficus carica. Methods Gas chromatography (GC) and gas chromatography-mass spectrometry (GC-MS) were used. Results The major components detected in volatile oil of the leaves were psoralen (10.12%), β-damascenone (10.17%), benzyl alcohol (4.56%), behenic acid (4.79%), and bergapten (1.99%), etc. The major components detected in volatile oil of the fruits were furfural (10.55%), 5-methyl-2-furaldehyde (10.1%), and benzeneacetaldehyde (6.59%), etc. Conclusion A total of 121 volatile constituents are identified in the leaves and 108 in the fruits of F. carica, among which 103 constituents are identified for the first time in the leaves and 100 in the fruits. Eighteen volatile constituents are identified in both leaves and fruits. | Jun LI Yu-zeng TIAN Bao-ya SUN Dan YANG Ji-ping CHEN Qi-ming MEN | 2012 | Chinese Herbal Medicines2012，4，1： | 4 |

| 3 | Content-adaptive robust error concealment for packet-lossy H.264 video streaming显示文摘In this paper, we present a spatio-temporal post-processing error concealment (EC) algorithm designed initially for a H.264 video-streaming scheme over packet-lossy networks. It aims at optimizing the subjective quality of the restored video under the constraints of low delay and computational complexity, which are critical to real-time applications and portable devices having limited resources. Specifically, it takes into consideration the physical property of motion field in order to achieve more meaningful perceptual video quality, in addition to the improved objective PSNR. Further, a simple bilinear spatial interpolation approach is combined with the improved boundary-match (B-M) based temporal EC approach according to texture and motion activity analysis. Finally, we propose a low complexity temporal EC method based on motion vector interpolation as a replacement of the B-M based approach in the scheme under low-computation requirement, or as a complement to further improve the scheme's performance in applications having enough computation resources. Extensive experiments demonstrated that the proposal features not only better reconstruction, objectively and subjectively, than JM benchmark, but also robustness to different video sequences. | LIAO Ning YAN Dan QUAN Zi-yi MEN Ai-dong | 2006 | Journal of Zhejiang University-Science A(Applied Physics & Engineering)2006，7，z1： | 0 |
| 4 | Robust spatio-temporal error concealment for packet- lossy H.264 video transmission显示文摘In this article, a spatio-temporal post-processing error concealment algorithm designed initially for a H.264 video-streaming scheme over packet-lossy networks has been presented. It aims at optimizing subjective quality of restored video and the conventional objective metric, peak signal-to-noise ratio (PSNR), as well, under the constraints of low delay and computational complexity, which are critical to real-time applications and portable devices having limited resources. Specifically, it takes into consideration physical property of motion to achieve more meaningful perceptual video quality. Further, a content-adaptive bilinear spatial interpolation approach and a temporal error concealment approach are combined under a unified boundary match criterion based on texture and motion activity analysis. Extensive experiments have demonstrated that the proposal not only result in better reconstruction, objectively and subjectively, than the reference software model benchmark, but also results in better robustness to different video sequences. | LIAO Ning YAN Dan QUAN Zi-yi MEN Ai-dong | 2006 | The Journal of China Universities of Posts and Telecommunications2006，13，3： | 0 |
| 5 | Taxonomy on crane flies in family Tipulidae and Limoniidae(Diptera: Tipuloidea) from Yaoluoping National Nature Reserve, Anhui, China显示文摘The paper reports 13 species from Yaoluoping National Nature Reserve, Anhui, China, including a new species and a new subspecies, Tipula(Emodotipula) alexanderi Men, sp. nov. and Nephrotoma impigra anqingensis Men, subsp. nov. The female of Libnotes(Libnotes) pseudonohirai Men, 2015 is described and illustrated for the first time. The males of Holorusia henana Yang, 1999 and Tipula(Vestiplex) jiangi Yang & Yang, 1991 are redescribed and illustrated with new morphological characters. A key to all species is provided. | Qiulei Men Zhiyong Lu Pingping Sheng Xiang Gui Zhizhong Wang Dan Mu | 2017 | Zoological Systematics2017，42，4： | 0 |
| 6 | Cost yield of different treatment strategies against Clonorchis sinensis infection显示文摘Background:Clonorchiasis is attributed to the ingestion of raw freshwater fsh harboring Clonorchis sinensis.Morbid‑ity control is targeted through the administration of antihelminthics.This study modelled the cost yield indicated by efectiveness and utility of diferent treatment strategies against clonorchiasis.Methods:About 1000 participants were enrolled from each of 14 counties selected from four provincial-level administrative divisions namely Guangxi,Guangdong,Heilongjiang and Jilin in 2017.Fecal examination was adopted to detect C.sinensis infection,while behavior of ingesting raw freshwater fsh was enquired.Counties were grouped into four categories based on prevalence,namely low prevalence group(<1%),moderate prevalence group(1–9.9%),high prevalence group(10–19.9%)and very high prevalence group(≥20%),while population were divided into three subgroups,namely children aged below 14 years old,adult female and adult male both aged over 14 years old.The average of cost efectiveness indicated by the cost to treat single infected cases with C.sinensis and of cost utility indicated by the cost to avoid per disability-adjusted life years(DALYs)caused by C.sinensis infection was calculated.Comparisons were performed between three treatment schedules,namely individual treatment,massive and selec‑tive chemotherapy,in which diferent endemic levels and populations were considered.Results:In selective chemotherapy strategy,the cost to treat single infected case in very high prevalence group was USD 10.6 in adult male,USD 11.6 in adult female,and USD 13.2 in children.The cost increased followed the decrease of endemic level.In massive chemotherapy strategy,the cost per infected case in very high prevalence group was USD 14.0 in adult male,USD 17.1 in adult female,USD 45.8 in children,which were also increased when the endemic level decreased.In individual treatment strategy,the cost was USD 12.2 in adult male,USD 15.0 in adult female and USD 41.5 in children in very high prevalence group;USD 19.2 in adult male,USD 34.0 in adult female,and USD 90.1 in children in high prevalence group;USD 30.4 in adult male,USD 50.5 in adult female and over USD 100 in children in moderate prevalence group;and over USD 400 in any population in low prevalence group.As to cost utility,the difer‑ences by treatment strategies,populations and endemic levels were similar to those in cost efectiveness.Conclusions:Both cost efectiveness and cost utility indicators are highly impacted by the prevalence and popula‑tion,as well as the treatment schedules.Adults especially men in the areas with a prevalence over 10%should be prioritized,in which selective chemotherapy was best and massive chemotherapy was also cost efective.In moderate endemic areas,the yield is not ideal,but selective chemotherapy for adult male may also be adopted.In low endemic areas,all strategies were high costly and new strategies need to be developed. | Men‑Bao Qian Chang‑Hai Zhou Hui‑Hui Zhu Ying‑Dan Chen Xiao‑Nong Zhou | 2021 | Infectious Diseases of Poverty2021，10，6： | 0 |
