| 1 | Onboard GRB trigger algorithms of SVOM-GRM显示文摘The Gamma-Ray Monitor(GRM)is a high energy detector onboard the future Chinese-French satellite named the Space-based multi-band astronomical Variable Object Monitor which is dedicated to studies of gamma-ray bursts(GRBs).This paper presents an investigation of the algorithms that look for GRBs by searching for a significant increase in the photon count rate for the computer onboard GRM.The trigger threshold and trigger efficiency,which are based on a given sample of GRBs,are calculated with the algorithms.The trigger characteristics of onboard instruments GRM and ECLAIRs are also analyzed.In addition,the impact of solar flares on GRM is estimated,and a method to distinguish solar flares from GRBs is investigated. | Dong-Hua Zhao Bo-Bing Wu Li-Ming Song Yong-Wei Dong Stphane Schanne Bertrand Cordier Jiang-Tao Liu | 2013 | Research in Astronomy and Astrophysics2013，13，11： | 2 |
| 18 | Defining a species in fungal plant pathology:beyond the species level显示文摘In plant pathology,the correct naming of a species is essential for determining the causal agents of disease.Species names not only serve the general purpose of concise communication,but also are critical for effective plant quarantine,prevent-ing the introduction of new pathogens into a territory.Many phytopathogenic genera have multiple species and,in several genera,disagreements between the multiple prevailing species concept definitions result in numerous cryptic species.Some of these species were previously called by various names;forma speciales(specialised forms),subspecies,or pathotypes.However,based on new molecular evidence they are being assigned into new species.The frequent name changes and lack of consistent criteria to delineate cryptic species,species,subspecies,forms,and races create increasing confusion,often making communication among biologists arduous.Furthermore,such ambiguous information can convey misleading evo-lutionary concepts and species boundaries.The aim of this paper is to review these concepts,clarify their use,and evaluate them by referring to existing examples.We specifically address the question,“Do plant pathogens require a different ranking system?”We conclude that it is necessary to identify phytopathogens to species level based on data from multiple approaches.Furthermore,this identification must go beyond species level to clearly classify hitherto known subspecies,forms and races.In addition,when naming phytopathogenic genera,plant pathologists should provide more information about geographic locations and host ranges as well as host specificities for individual species,cryptic species,forms or races.When describing a new phytopathogen,we suggest that authors provide at least three representative strains together with pathogenicity test results.If Koch’s postulates cannot be fulfilled,it is necessary to provide complementary data such as associated disease severity on the host plant.Moreover,more sequenced collections of species causing diseases should be published in order to stabilise the boundaries of cryptic species,species,subspecies,forms,and races. | Ishara S.Manawasinghe Alan J.L.Phillips Jianping Xu Abhaya Balasuriya Kevin D.Hyde Łukasz Stępień Dulanjalee L.Harischandra Anuruddha Karunarathna Jiye Yan Janith Weerasinghe Mei Luo Zhangyong Dong Ratchadawan Cheewangkoon | 2021 | Fungal Diversity2021，，4： | 0 |
