| 1 | Defending Against Link Failure in Virtual Network Embedding Using a Hybrid Scheme显示文摘Nowadays network virtualization is utterly popular.As a result,how to protect the virtual networks from attacking on the link is increasingly important.Existing schemes are mainly backup-based,which suffer from data loss and are helpless to such attacks like data tampering.To offer high security level,in this paper,we first propose a multipath and decision-making(MD) scheme which applies multipath simultaneously delivery and decision-making for protecting the virtual network.Considering different security requirement for virtual link,we devise a hybrid scheme to protect the virtual links.For the critical links,MD scheme is adopted.For the other links,we adopt the Shared Backup Scheme.Our simulation results indicate the proposed scheme can significantly increase the security level of the critical link high in the loss of less acceptance ratio. | Jianjian Ai Hongchang Chen Zehua Guo Guozhen Cheng | 2019 | China Communications2019，16，1： | 1 |
| 2 | Applications and grants of National Natural Science Foundation of China’s General Program in cardiovascular research:a 10-year review显示文摘Cardiovascular diseases(CVDs)are the major threats to global human health and the leading causes of mortality and morbidity in China(Liu et al.,2019).Although various strategies have been developed,the prevalence of CVDs is still increasing in China,and many CVDs cannot be managed well(Liu et al.,2019)because of the lack of full elucidation on many basic issues. | Juejin Wang Zhaoyang Chen Hongchang Guo Rui Wang Ruijuan Sun | 2023 | Science China(Life Sciences)2023，66，3： | 1 |
| 3 | Functionalized carbon dots for corrosion protection:Recent advances and future perspectives显示文摘Metal corrosion causes significant economic losses,safety issues,and environmental pollution.Hence,its prevention is of immense research interest.Carbon dots(CDs)are a new class of zero-dimensional carbon nanomaterials,which have been considered for corrosion protection applications in recent years due to their corrosion inhibition effect,fluorescence,low toxicity,facile chemical modification,and cost-effectiveness.This study provides a comprehensive overview of the synthesis,physical and chemical properties,and anticorrosion mechanisms of functionalized CDs.First,the corrosion inhibition performance of different types of CDs is introduced,followed by discussion on their application in the development of smart protective coatings with self-healing and/or self-reporting properties.The effective barrier formed by CDs in the coatings can inhibit the spread of local damage and achieve self-healing behavior.In addition,diverse functional groups on CDs can interact with Fe^(3+)and H^(+)ions generated during the corrosion process;this interaction changes their fluorescence,thereby demonstrating self-reporting behavior.Moreover,challenges and prospects for the development of CD-based corrosion protection systems are also presented. | Li Zhao Jinke Wang Kai Chen Jingzhi Yang Xin Guo Hongchang Qian Lingwei Ma Dawei Zhang | 2023 | International Journal of Minerals,Metallurgy and Materials2023，30，11： | 0 |
| 4 | Expression and purification of cysteine mutation isoforms of rat lipocalin-type prostaglandin D synthase for nuclear magnetic resonance study显示文摘Lipocalin 类型前列腺素(PG ) D 合酶(L-PGDS ) 是显示酶的活动的 lipocalin 总科的唯一的成员。它与高亲密关系并且也绑脂性的 ligands 能催化 PGH (2 ) 生产 PGD (2 ) 。三半胱氨酸残余, Cys (65 ) , Cys (89 ) ,和在 L-PGDS 的 Cys (186 ) ,在所有种类之中被保存,哪个 Cys (89 ) 和 Cys (186 ) 残余形式一座二硫化物桥。在这研究,我们在蛋白质的结构上澄清了 thiol 组的效果并且由指导地点的傻瓜发育不全调查了老鼠 L-PGDS 的 Cys 残余的结构的意义。四异种被与丙氨酸代替 Cys 残余在这三残余之中识别二硫键的正确形成构造。老鼠 L-PGDS 的结构上的 thiol 组的效果被这些异种也识别。HSQC 实验的分析显示这些酶都适当地与明确的三级结构被合拢。当第一向 3-D 走原子磁性的回声答案结构,我们在 Escherichia 关口 i 优化了 recombinant 老鼠 L-PGDS 的表示并且证实产出大量纯同位素的联盟者的一个有效、经济的纯化协议把老鼠 L-PGDS 标记。任务的结果显示用这个表达式系统获得的野类型的老鼠 L-PGDS 对 3-D 的决心合适原子磁性的回声解决方案结构。 | Jiafu Liu Kejiang Lin Chenyun Guo Hongchang Gao Yihe Yao and Donghai Lin | 2008 | Acta Biochimica et Biophysica Sinica2008，40，6： | 0 |
| 5 | Single somatic cell development and differentiation in the gametiphytic blades of Pyropia suborbiculata (Bangiales, Rhodophyta)显示文摘Conchospores released from a wild-type strain of Pyropia suborbiculata were cultured in the laboratory for 20-80 days.Mother blades of different ages were enzymatically isolated to obtain single cells,which then developed into different types of regenerative plants within a liquid medium.These regenerative plant types includes:normal blades,abnormal blades,cell-masses,and sexual cell-masses.The age of mother blades distinctly affected the number and proportion of each type of regenerative plants.When the age of mother blades increased from 20 to 80 days,the proportion of normal blades in the isolated cells sharply decreased,the percentage of abnormal blades increased,and the proportion of cell-masses was relatively unchanged.After 40 days of cultivation,sexual cell-masses appeared in regenerated plants derived from the single blade cells of the PS-WT strain,and gradually increased with mother cell age.In addition,the proportion of normal blades decreased in regenerated plants sourced from the basal to apical parts of the same alga,while the proportion of abnormal blades and cell-masses increased.In summary,the isolated cells of the gametophytic blade of P.suborbiculata developed into different types of regenerated plantlets in vivo due to the different stages of cell differentiation.We preliminarily concluded that the differentiation from conchospores to the sexual cells could be divided into at least seven different groups. | Wenxia Guo Hongchang Ding Xinghong Yan | 2021 | Aquaculture and Fisheries2021，6，5： | 0 |
| 6 | Microbiologically Influenced Corrosion Behavior of Fe_(40)(CoCrMnNi)_(60) and Fe_(60)(CoCrMnNi)_(40) Medium Entropy Alloys in the Presence of Pseudomonas Aeruginosa显示文摘In this work,the microbiologically influenced corrosion(MIC)of Fe_(40)(CoCrMnNi)_(60) and Fe_(60)(CoCrMnNi)_(40) medium entropy alloys(MEAs)induced by Pseudomonas aeruginosa(P.aeruginosa)was investigated.Corrosion behaviors during 14 days of immersion in sterile and P.aeruginosa-inoculated culture media are presented.Under sterile conditions,both MEAs exhibited good corrosion resistance against the culture medium solution.In the presence of P.aeruginosa,the pitting corrosion of MEAs was promoted.The results of inductively coupled plasma‒mass spectrometry(ICP‒MS)and potentiodynamic polarization tests showed that the presence of P.aeruginosa promoted the selective dissolution of passive film and accelerated the corrosion of MEAs.The results of X-ray photoelectron spectroscopy(XPS)and Mott-Schottky measurements further demonstrated the degradation effect of P.aeruginosa on the passive film.Compared with Fe_(60)(CoCrMnNi)_(40),Fe_(40)(CoCrMnNi)_(60) manifested better resistance to the MIC caused by P.aeruginosa,which may be attributed to more Cr oxides and fewer Fe oxides of the passive film. | Weiwei Chang Yangyang Li Huaibei Zheng Hongchang Qian Dawei Guo Shuyuan Zhang Yuntian Lou Chi Tat Kwok Lap Mou Tam Dawei Zhang | 2023 | Acta Metallurgica Sinica(English Letters)2023，36，3： | 0 |
