A study with substantially more genetic loci (352 markers) did not increase support for its position within the family28. Fig. 1: Time-calibrated phylogenetic tree of brush-footed butterflies (Nymphalidae) with biogeographic distribution of extant species and branch net diversification rate estimated ...
The process of using expression trees for analysis starts with a binary tree. First, we compose an expression tree according to the priority of the result of lexical analysis. The leaf nodes of the expression tree are operands, and the internal nodes are operators. In this case, the colon h...
Indexes are numbered beginning with 1, in the same order as shown by SHOW INDEX for the table. The index map value N is a bitmask value that indicates which indexes are candidates. For example, a value of 0x19 (binary 11001) means that indexes 1, 4, and 5 are considered. Recursive...
一.OptimizingQueries with EXPLAIN The EXPLAINstatement can be used either as a way to obtain information about how MySQLexecutes a statement, or as a synonym for DESCRIBE: (1)When youprecede a SELECT statement with the keyword EXPLAIN, MySQL displays informationfrom the optimizer about the query...

Regions with a high prevalence of cases are extracted by means of binary classifiers, then the most relevant variables for the classification are determined, and the robustness of the analysis is assessed. Our results show that the most meaningful features to identify high-prevalence regions include...
