How this list is built · 这份榜单怎么来的
Sources. PubMed, OpenAlex and bioRxiv are polled daily for aptamer-related publications; records are de-duplicated by DOI.
Topic filter. A paper enters this list when its title or abstract matches any of: food, agricult*, mycotoxin*, aflatoxin*, ochratoxin*, pesticide*, veterinary drug*, antibiotic residue*, Salmonella, E coli, Listeria (SQLite FTS5, case-insensitive, * is a prefix wildcard). A paper can belong to several topics.
Ranking. composite = 0.45×log(IF) + 0.35×log(citation velocity) + 0.10×social + 0.10×recency, scaled to 100. Citation velocity is citations per day since publication, so a recent paper accruing citations quickly can outrank an older one with a larger total. The recency term decays linearly to zero at 30 days, so anything older than a month is ranked on impact and citation velocity alone — this list therefore tilts towards recent work by design.
What this is not. The ranking is computed from metadata — journal impact factor, citation counts, recency — not from reading the papers. It is a triage aid for deciding what to read, not a quality judgement or a substitute for a systematic review. Impact factor is missing for some venues (preprints in particular) and those papers score lower than their content may deserve.
这份榜单由元数据算出——期刊影响因子、引用数、时效性——而不是通过阅读论文得到。它是决定「先读哪篇」的分诊工具，不是质量判断，也不能替代系统综述。部分来源（尤其预印本）没有影响因子，其得分会低于内容应得的水平。
