| 1 | Evaluating the reliability of microsatellite genotyping from low-quality DNA templates with a polynomial distribution model显示文摘Molecular studies using trace DNA, such as from museum specimens, ancient or forensic samples and samples obtained noninvasively, often have a common problem of low quality of DNA templates. Amplification errors, such as allelic dropout and false allele, may arise during polymerase chain reaction (PCR) using such samples. A mathematical model which treats homozygotes and heterozygotes discriminately has been developed to measure sample quality and compute the confidence level of using multipletube approaches. We use plucked hair samples collected from 26 individual Sichuan snub-nosed monkeys (Rhinopithecus roxel- lana) to test the model. In this case, a confidence level of 99% can be achieved by three positive PCRs. If the sample quality is very poor and requires many PCR replicates, an alternative multiplestep genotyping method is recommended. This model enables researchers to optimize experimental protocols through pilot studies and obtain reliable genetic information using noninvasive sampling method. | HE Gangi HUANG Kang GUO SongTao JI WeiHong QI XiaoGuang REN Yi JIN XueLin LI BaoGuo | 2011 | Chinese Science Bulletin2011，56，24： | 8 |
| 2 | Capacity bounds of transmit beamforming over MISO time-varying channels with imperfect feedback显示文摘In wireless multiple input single output (MISO) systems, transmit beamforming using feedback of quantized channel state information (CSI) can provide both diversity gain and array gain with simple imple- mentation. Most of previous researches include several ideal assumptions, such as block-fading channels, perfect CSI at the receiver, or error-free and zero-delay feedback link. This paper investigates a more realistic Jakes' time-varying MISO Rayleigh fading channel with CSI estimation error and feedback delay, derives the upper and lower bounds on the ergodic capacity, and obtains the optimal frame length according to the capacity lower bound given the normalized feedback bits. The numerical and simulation results show that the derived upper and lower bounds on the capacity is quite close, increasing channel estimation error or Doppler spread will reduce the capacity bounds, and the optimal frame length can maximize the capacity lower bound. | ZHANG Lei WU Gangi LI ShaoQian | 2010 | Science China(Information Sciences)2010，53，7： | 5 |

| 9 | Evaluating Natural Forest Management Efficiency显示文摘According to the structure-based forest management theory,the appraisal indices system of natural forest management efficiency was established from spatial utilization,species diversity, constructive species competition and tree composition,which could be used to depict stand status,and its metewand was given.Relative weight was endowed by The Analytic Hierarchy Process (AHP),and then the conception of natural forest management efficiency comprehensive appraisal index was put forward for the first time and applied to four different sampling plots of natural forest, three of them from Dongdapo forest region,Jiaohe, Jilin province,and one from Baihua forest area, Xiaolongshan,Gansu province,China.The results are as following:the stand status was obviously improved after being managed and plot A,B got a mark of 'medium' while C and D were 'perfect'. From high to low,the arrangement of forest management efficiency comprehensive appraisal index was C>D>A>B.This appraisal result abided by the phenomenon detected in the practical field.The forest management efficiency comprehensive appraisal index brought up in this paper could be taken as a way of comprehensive quantitative change of stand state which directly reflects the effort of forest management and affords scientific basis of natural forest management effort. | Li Yuanfa Zhao Zhonghua Hu Yanbo Hui Gangying | 2012 | Chinese Forestry Science and Technology2012，11，3： | 0 |
