back. The frame rate is calculated by first finding the span of time that the program consumes for 20 frames, and then calculating how many spans can be contained within 100s. The number of spans in 100s is multiplied by 20 to draw several frames within 100s, and the number of frames drawn within 1s can be obtained by dividing by 100. 5.MainActivity class Mai

fundamentally solve the problem.Java output stream InputStream: when the input stream of the socket is read, it blocks until the following three events occur. have data to read; The available data has been read; A null pointer or IO exception occurred. This means that when the other side sends the data request or the response message is slow (the network transmission is slow), the read write stream side of the communication thread will be blocked for a long time, if the ot

. Linkage disequilibrium: Nonrandom Association of alleles at the or more loci. Linked selection: Change of the allele frequency of loci genetically Linked to a locus under selection. Includes allele frequency change due to any action of selection positive selection or Negative/purifying selection (also R Eferred to as background selection). Locus/loci: A position in the genome, could is a single nucleotide position or 1000s of base pairs of DNA sequence , it can correspond to a gene or

For details, see this GitHub commit, a new change that composer just introduced: https://github.com/composer/composer/commit/ac676f47f7bbc619678a29deae097b6b0710b799 The change is to use the gc_disable() function (PHP 5.3+) to turn off PHP's cyclic reference collector before calculating dependencies. The test in the comment area shows that the efficiency of this change is enormous (246s->100s, 196->104s,138->26s, etc.). What is the underlying reason
