已知一组数据10，8，6，10，8，13，11，10，12，7，10，11，10，9，12，11，9，12，9，8，那么频率为0.3的范围是（　　）A．6～7B．8～9C．10～11D．12～13
主讲：赵秀辉
【思路分析】
根据频率的计算公式，求出选项中各段的频率，即可作出判断．
【解析过程】
解：共有20个数据，其中6～7的频率是2÷20=0.1；8～9的频率是6÷20=0.3；10～11的频率是8÷20=0.4；12～13的频率是4÷20=0.2．故选B．
考查了频率的计算方法：频率=频数÷总数．

KEYWORDS: Pharmaceutical Targets for Drug D G-Protein Coupled R Scoring M Hit Rates
JOURNAL NAME:
Sep 05, 2014
Target identification is a
critical step following the discovery of small molecules that elicit a
biological phenotype. G-protein coupled recaptors (GPCRs) are among the most
important drug targets for the pharmaceutical industry. The present work seeks to
provide an in silico model of known GPCR protein fishing technologies in
order to rapidly fish out potential drug targets on the basis of amino acid sequences
and seven transmembrane regions (TMs) of GPCRs. Some scoring matrices were trained
on 22 groups of GPCRs in the GPCRDB database. These models were employed to predict
the GPCR proteins in two groups of test sets. On average, the mean correct rate
of each TM of 38 GPCRs from two test sets (ST23 and ST24)
was found 62% and 57.5%, respectively, using training set 18 (SLD18);
the mean hit rate of each TM of 38 GPCRs from ST23 and ST24 was found 68.1% and 64.7%, respectively. Based on the scoring matrices of
PreMod, the mean correct rate of each TM of GPCRs from ST23 and ST24 was found 62% and 62.04%, the mean
hit rate of each TM of GPCRs from ST23 and ST24 was found 67.7% and 68.0%, respecttively. The means of GPCRs in ST23 based on SLD18 is close to those based on PreM whereas
the means of GPCRs in ST24 based on&SLD18 is less than those based on PreMod. Moreover, the accuracy (“2”) and validity
(“2 + 1”) rates of prediction all seven TMs of 38 GPCRs by the scoring matrices
of PreMod are more than those by SLD18, SLA14 and SLA3; whereas the hit rates (94.74% and 97.37%) by
PreMod are less than those of&SLA3 but bigger than
those of&SLD18 and SLA14,
respectively. This is the reason that we choose PreMod to predict some
potential drug targets. 22 GPCR proteins in the sense chain of chromosome 19
constructing validation set were predicted and validated by PreMod whose hit
rate is up to 90.91%. Further evaluation is under investigation.中国电子资料网--电子元件--电子维修--1S953,1S954,1S955,1SS53,1SS54,1SS55,1S6,1S8,RD2.4M,RD2.7M,RD3.0M,RD3.3M,RD3.6M,RD3.9M,RD4.3M,RD4.7M,RD5.1M,RD5.6M,RD6.2M,RD6.8M,RD7.5M,RD8.2,RD9.1M,RD10M,RD11M,RD12M,RD13M,RD15M,RD16M,RD18M,RD20M,RD22M,RD24M,RD2.0E,RD2.2E,RD2.4E,RD2.7E,RD3.0E,RD3.3E,RD3.6E,RD3.9E,RD2.0F,RD2.2F,RD2.4F,RD2.7F,RD3.0F,RD3.3F,RD3.6F,RD3.9F,RD4.3E,RD4.3F,RD4.7J,RD4.7E,RD4.7F,RD5.1J,RD5.1E,RD5.1F,RD5.6J,RD5.6E,RD5.6F,RD6.2J,RD6.2E,RD6.2F,RD6.8J,RD6.8E,RD6.8F,RD7.5J,RD7.5E,RD7.5F,RD8.2J,RD8.2E,RD8.2F,RD9.1J,RD9.1E,RD9.1F,RD10J,RD10E,RD10F,RD11J,RD11E,RD11F,RD12J,RD12E,RD12F,RD13J,RD13E,RD13F,RD15J,RD15E,RD15F,RD16J,RD16E,RD16F,RD18J,RD18E,RD18F,RD20J,RD20E,RD20F,RD22J,RD22E,RD22F,RD24J,RD24E,RD24F,RD27J,RD27E,RD27F,RD30J,RD30E,RD30F,RD33J,RD33E,RD33F,RD36J,RD36E,RD36F,RD39J,RD39E,RD39F,RD43E,RD43F,RD47E,RD47F,RD51E,RD51F,RD56E,RD56F,RD68E,RD68F,RD75E,RD75F,RD82E,RD82F,RD91E,RD100E,RD110E,RD120E.PDF
