Statistical Model on the Time and Time Difference Error of Arrival in TDOA Location Estimation

Additional time delay of arrival resulted from non-line of sight(NLOS)propagation and muti-path effect in(cellular) environment is the dominant factor resulting in TDOA location error,study on the statistical property of TDOA error is useful for improving the accuracy of TDOA location.Based on the exponential distribution property of NLOS propagation delay,and considering the system error resulted from the signal detection,the authors establish a statistical model of arrival time and a model of TDOA error distribution by statistics when non-light of sight and multi-path propagation exist.The models reflect the statistical property of arrival time and TDOA error in cell network,the simulation shows that the proposed models have a good accuracy and a satisfactory behavior.

八个竹种海涂引种试验报告

本文从土壤含盐量着手对八个竹种在引种成活率、新竹抽发数及其质量、角竹笋产量等方面进行了较系统的研究。结果表明,土壤盐分影响竹子的生长发育,此影响一般随含盐量的增加而增加;不同竹种对土壤盐分的适应能力不同;角竹笋能获得高产,单产达20800kg/ha。参照产地母竹和引种地新竹的生长情况,我们建议:海涂地区发展竹子时可选用角竹、桂竹和红竹。     

亲环素基因在烟草不同器官及叶片不同发育时期的表达规律研究

通过对烟草中3个亲环素家族基因（CyPl、CyP2、CyP40）表达模式的研究,结果显示：在不同发育时期中,CyPI在烟草移栽后40、50、60d时表达量较高,CyP2则是在移栽后30、40、60d表达量较高,而CyP40只在移栽后60d表达量较高。在不同组织部位及器官的表达中,3个亲环素家族基因在中部叶和下部叶中表达均较强。在烟草根中主要表达CyPl和CyP40基因,CyP40还在花中表达较高,而CyP2基因的主要表达器官为叶片。

Changes in the blood lactate dehydrogenase measurements in canines and felines following the international standardization of the assay method

Lactate dehydrogenase (LDH) in blood is measured using the Japanese Society of Clinical Chemistry (JSCC) method in Japan and the International Federation of Clinical Chemistry (IFCC) method in other countries. In human clinical practice, the IFCC method replaced the JSCC method due to international standardization. Moreover, veterinary LDH measurement will also eventually shift to the IFCC method. However, the relationship between the IFCC and JSCC methods for LDH in various animals and whether they can be equated or not have not yet been investigated. This study aimed to present the changes in measurements in canines and felines after switching to the IFCC method. The plasma LDH activity of canines (N=177) and felines (N=115), who visited a secondary care veterinary clinic, was measured using the JSCC and IFCC methods. The IFCC/JSCC ratio was <1.0 in 85% of canines and 88% of felines, indicating that the IFCC method tended to show lower values than the JSCC method, presumably because LDH5 is dominant among the LDH isozymes in canines and felines. The increase in the systematic errors of both assays was in the high value range, with some samples exceeding the error tolerance from near the upper end of the reference range. When switching to the IFCC method for LDH measurement in canines and felines, each institution should consider whether the reference range and clinical diagnostic values established by the JSCC method are appropriate for continued use.
