Studies carried out in natural forests are few. It is in this context that this inventory of entomofauna was carried out from April to July 2022 in the Scientific City Forest. The general objective is to contribute to the knowledge of the trapping, mowing and sight hunting;the three types of traps used are: Barber pots, colored plates and aerial traps. This study made it possible to invent 1523 specimens belonging to 106 species, 99 genera, 59 families and 12 orders. The order Diptera is the most abundant and richest in species (47% and 26%). This order is followed by Hymenoptera (23% and 23%). Formicidae (14%) and Calliphoridae (13%) are the most abundant families. The Formicidae family presents the greatest species richness (7%), Calliphora sp and Polyrhachis cyaniventris present the highest specific relative abundance of the entire collection. These preliminary results of the entomofauna of Scientific City constitute a database. However, this study must be continued and extended to other areas of Brazzaville, using other capture techniques and taking into account the seasons.展开更多

文摘With the rise of data-intensive research,data literacy has become a critical capability for improving scientific data quality and achieving artificial intelligence(AI)readiness.In the biomedical domain,data are characterized by high complexity and privacy sensitivity,calling for robust and systematic data management skills.This paper reviews current trends in scientific data governance and the evolving policy landscape,highlighting persistent challenges such as inconsistent standards,semantic misalignment,and limited awareness of compliance.These issues are largely rooted in the lack of structured training and practical support for researchers.In response,this study builds on existing data literacy frameworks and integrates the specific demands of biomedical research to propose a comprehensive,lifecycle-oriented data literacy competency model with an emphasis on ethics and regulatory awareness.Furthermore,it outlines a tiered training strategy tailored to different research stages—undergraduate,graduate,and professional,offering theoretical foundations and practical pathways for universities and research institutions to advance data literacy education.

文摘Knowledge graphs convey precise semantic information that can be effectively interpreted by neural networks,and generating descriptive text based on these graphs places significant emphasis on content consistency.However,knowledge graphs are inadequate for providing additional linguistic features such as paragraph structure and expressive modes,making it challenging to ensure content coherence in generating text that spans multiple sentences.This lack of coherence can further compromise the overall consistency of the content within a paragraph.In this work,we present the generation of scientific abstracts by leveraging knowledge graphs,with a focus on enhancing both content consistency and coherence.In particular,we construct the ACL Abstract Graph Dataset(ACL-AGD)which pairs knowledge graphs with text,incorporating sentence labels to guide text structure and diverse expressions.We then implement a Siamese network to complement and concretize the entities and relations based on paragraph structure by accomplishing two tasks:graph-to-text generation and entity alignment.Extensive experiments demonstrate that the logical paragraphs generated by our method exhibit entities with a uniform position distribution and appropriate frequency.In terms of content,our method accurately represents the information encoded in the knowledge graph,prevents the generation of irrelevant content,and achieves coherent and non-redundant adjacent sentences,even with a shared knowledge graph.

文摘The article reviews the history and scientific contributions of the soil zoology school at Moscow Pedagogical State University,founded by Academician Mercury Sergeevich Gilyarov and led by Professor Nina Mikhailovna Chernova.A key theoretical contribution from this school was the development of succession theory,which describes changes in soil invertebrate communities during plant litter decomposition.The school’s primary research focus has been on soil microarthropods,particularly springtails(Collembola)and mites—groups that are crucial for soil fertility and bioindication yet remain understudied.We trace the school’s progress in the taxonomy,faunistic studies,and ecology of soil invertebrates,emphasizing its foundation in field studies and laboratory experiments.Though its development was further strengthened through national and international collaborations,many of N.M.Chernova’s seminal ideas are not widely known outside Russia due to language barriers and limited access to publications.Her students continue to address this issue while advancing the study of soil zoology,ecology,and its history.
