1Ag/Ag_3PO_4/g-C_3N_4三元复合光催化剂的制备及其可见光驱动下的光催化活性增强(英文)显示文摘报道了一种新型Ag/Ag3PO4/g-C3N4三元复合光催化剂的制备及其半导体界面处的快速载流子分离所引起的光催化活性的显著增强效应.通过X射线衍射,扫描电子显微镜,紫外-可见吸收光谱以及光致发光光谱等就其晶体结构、形貌、组分、光学吸收以及载流子的快速分离行为进行了表征与分析.以罗丹明B作为模型化合物分子,研究发现,所制备的Ag/Ag3PO4/g-C3N4三元复合光催化剂在可见光照射下表现出比Ag3PO4以及Ag3PO4/g-C3N4二元催化剂更为优异的光催化活性.研究认为,Ag3PO4表面尺寸约为40 nm的Ag纳米粒子在可见光下受激所产生的等离子表面共振效应以及Ag3PO4与g-C3N4界面处所形成的类似异质结结构对所制备的Ag/Ag3PO4/g-C3N4三元复合光催化剂光催化活性的显著增强起到重要作用.沈凯 Mohammed Ashraf Gondal Rashid Ghulam Siddique 施珊 王斯琦 孙江波 徐庆宇 2014催化学报2014,35,1:14
2Survey of intrusion detection systems:techniques,datasets and challenges显示文摘Cyber-attacks are becoming more sophisticated and thereby presenting increasing challenges in accurately detecting intrusions.Failure to prevent the intrusions could degrade the credibility of security services,e.g.data confidentiality,integrity,and availability.Numerous intrusion detection methods have been proposed in the literature to tackle computer security threats,which can be broadly classified into Signature-based Intrusion Detection Systems(SIDS)and Anomaly-based Intrusion Detection Systems(AIDS).This survey paper presents a taxonomy of contemporary IDS,a comprehensive review of notable recent works,and an overview of the datasets commonly used for evaluation purposes.It also presents evasion techniques used by attackers to avoid detection and discusses future research challenges to counter such techniques so as to make computer systems more secure.Ansam Khraisat Iqbal Gondal Peter Vamplew Joarder Kamruzzaman 2019Cybersecurity2019,2,1:13
3Current systematic reviews and meta-analyses of COVID-19显示文摘BACKGROUND Coronavirus disease 2019(COVID-19)has left a significant impact on the world's health,economic and political systems;as of November 20,2020,more than 57 million people have been infected worldwide,with over 1.3 million deaths.While the global spotlight is currently focused on combating this pandemic through means ranging from finding a treatment among existing therapeutic agents to inventing a vaccine that can aid in halting the further loss of life.AIM To collect all systematic reviews and meta-analyses published related to COVID-19 to better identify available evidence,highlight gaps in knowledge,and elucidate further meta-analyses and umbrella reviews that are yet to be performed.METHODS We explored studies based on systematic reviews and meta-analyses with the keyterms,including severe acute respiratory syndrome(SARS),SARS virus,coronavirus disease,COVID-19,and SARS coronavirus-2.The included studies were extracted from Embase,Medline,and Cochrane databases.The publication timeframe of included studies ranged between January 01,2020,to October 30,2020.Studies that were published in languages other than English were not considered for this systematic review.The finalized full-text articles are freely accessible in the public domain.RESULTS Searching Embase,Medline,and Cochrane databases resulted in 1906,669,and 19 results,respectively,that comprised 2594 studies.515 duplicates were subsequently removed,leaving 2079 studies.The inclusion criteria were systematic reviews or meta-analyses.860 results were excluded for being a review article,scope review,rapid review,panel review,or guideline that produced a total of 1219 studies.After screening articles were categorized,the included articles were put into main groups of clinical presentation,epi-demiology,screening and diagnosis,severity assessment,special populations,and treatment.Subsequently,there was a second subclassification into the following groups:gastrointestinal,cardiovascular,neurological,stroke,thrombosis,anosmia and dysgeusia,ocular manifestations,nephrology,cutaneous manifestations,D-dimer,lymphocyte,anticoagulation,antivirals,convalescent plasma,immunosuppressants,corticosteroids,hydroxychloroquine,renin-angiotensin-aldosterone system,technology,diabetes mellitus,obesity,pregnancy,children,mental health,smoking,cancer,and transplant.CONCLUSION Among the included articles,it is clear that further research is needed regarding treatment options and vaccines.With more studies,data will be less heterogeneous,and statistical analysis can be better applied to provide more robust clinical evidence.This study was not designed to give recommendations regarding the management of COVID-19.Mahmoud Nassar Nso Nso Mostafa Alfishawy Anastasia Novikov Salim Yaghi Luis Medina Bahtiyar Toz Sofia Lakhdar Zarwa Idrees Yungmin Kim Dawa Ongyal Gurung Raheel S Siddiqui David Zheng Mariam Agladze Vikram Sumbly Jasmine Sandhu Francisco Cuevas Castillo Nadya Chowdhury Ravali Kondaveeti Sakil Bhuiyan Laura Guzman Perez Riki Ranat Carlos Gonzalez Harangad Bhangoo John Williams Alaa Eldin Osman Joyce Kong Jonathan Ariyaratnam Mahmoud Mohamed Ismail Omran Mariely Lopez Akwe Nyabera Ian Landry Saba Iqbal Anoosh Zafar Gondal Sameen Hassan Ahmed Daoud Bahaaeldin Baraka Theo Trandafirescu Vincent Rizzo 2021World Journal of Virology2021,10,4:2
4Continuing challenges in the diagnosis and management of obscure gastrointestinal bleeding显示文摘The diagnosis and management of obscure gastrointestinal bleeding(OGIB) have changed dramatically since the introduction of video capsule endoscopy(VCE) followed by deep enteroscopy and other imaging technologies in the last decade. Significant advances have been made, yet there remains room for improvement in our diagnostic yield and treatment capabilities for recurrent OGIB. In this review, we will summarize the latest technologies for the diagnosis of OGIB, limitations of VCE, technological enhancement in VCE, and different management options for OGIB.Veronica Baptista Neil Marya Anupam Singh Abbas Rupawala Bilal Gondal David Cave 2014World Journal of Gastrointestinal Pathophysiology2014,5,4:2
