摘要： Two software-only prefix encoding techniques employ encoding look-up tables to produce contributions to the encoded bit stream that are incremented in integral numbers of bytes to facilitate accelerated encoding rates at the expense of an acceptable trade-off in increased memory size requirements. The first technique, referred to as offset-based encoding, employs encoding tables which eliminate most of the bit-based operations that need to be performed by a prefix encoder without inordinately expanding memory requirements. In offset-based encoding, a Huffman table is employed which contains information for each number of bits by which the length of a Huffman word is offset from an integral number of bytes. The encoding method generates bytes of encoded data, even though the Huffman code has variable length code words for each symbol to be encoded. The second technique, referred to as byte-based encoding, employs a byte-based Huffman encoding table which operates even faster than the offset-based encoding scheme because it does not employ any bit-based operations at all; however, this is achieved at the expense of a considerable expansion in memory requirements.
摘要翻译：两个仅软件前缀编码技术采用编码查找表来产生对以字节为单位递增的编码比特流的贡献，以便以增加的存储器大小要求的可接受的折衷为代价来加速编码速率。称为基于偏移的编码的第一种技术使用编码表，其消除了需要由前缀编码器执行的大部分基于位的操作，而不会不断扩大存储器需求。在基于偏移的编码中，使用霍夫曼表，其包含每个比特数的信息，通过该信息，霍夫曼字的长度与整数字节偏移。编码方法生成编码数据的字节，即使霍夫曼代码对于要编码的每个符号具有可变长度代码字。被称为基于字节的编码的第二种技术采用基于字节的霍夫曼编码表，其基于偏移的编码方案运行甚至更快，因为它完全不采用任何基于位的操作; 然而，这是以大量的内存需求扩张为代价的。

摘要： According to an allele determining device 1 that determines a single nucleotide polymorphism of a gene, an approximating unit 4 approximates an optical measurement result obtained by observing a reagent that reacts with a specific base sequence of a gene, to a logistic curve that is a curve using light intensity and time as parameters. A determining unit 5 determines a single nucleotide polymorphism using a plateau value or an inflection point that is a characteristic point of the approximated logistic curve, the measured light intensity, and the like.

摘要： A batch or continuous process produces highly pure 3,3',5,5'-tetra-t-butylbiphenol suitable as a starting material for the synthesis of 4,4'-biphenol. The process for producing 3,3',5,5'-tetra-t-butylbiphenol comprises conducting an oxidation coupling of purified 2,6-di-t-butylphenol(i) or crude 2,6-di-t-butylbiphenol(ii), said crude 2,6-di-t-butylphenol being obtained by reacting isobutylene with phenol in the presence of an aluminum catalyst, and removing the aluminum catalyst. The 2,6-di-t-butylphenol is oxidatively coupled in an alkali metal catalyst mixture comprising (1) an alkali metal catalyst and alkylphenols, or (2) alkali metal catalyst, alkylphenols and phenol to produce 3,3',5,5'-tetra-t-butylbiphenol. The oxidative coupling is conducted together with 10-30% by weight of phenol and/or t-butylphenol per 100% by weight of 2,6-di-t-butylphenol in the presence of an alkali metal catalyst.
