Lung cancer susceptibility locus at 5p15.33

We carried out a genome-wide association study of lung cancer (3,259 cases and 4,159 controls), followed by replication in 2,899 cases and 5,573 controls. Two uncorrelated disease markers at 5p15.33, rs402710 and rs2736100 were detected by the genome-wide data (P = 2 x 10(-7) and P = 4 x 10(-6)) and replicated by the independent study series (P = 7 x 10(-5) and P = 0.016). The susceptibility region contains two genes, TERT and CLPTM1L, suggesting that one or both may have a role in lung cancer etiology.     

Adaptive detection of range-spread targets in homogeneous and partially homogeneous clutter plus subspace interference

Adaptive detection of range-spread targets is considered in the presence of subspace interference plus Gaussian clutter with unknown covariance matrix. The target signal and interference are supposed to lie in two linearly independent subspaces with deterministic but unknown coordinates. Relying on the two-step criteria, two adaptive detectors based on Gradient tests are proposed, in homogeneous and partially homogeneous clutter plus subspace interference, respectively. Both of the proposed dete...     

软土地层基坑群模型试验相似材料研制及应用

针对基坑群连续开挖存在的耦合效应,首先确定相似材料配比方案,其次通过正交试验得出合理的配比材料,进而设计基坑群模型试验,研究了两侧基坑叠加作用影响下车站基坑的围护结构和土体表层变形。研究结果表明：满足该软土地层相似常数的土层材料配比为石英砂：滑石粉：双飞粉：膨润土：水=0.27：0.27：0.232：0.058：0.17;相较于无邻近基坑开挖的地铁站,旁侧存在基坑开挖时由于相邻墙体引起的墙后土拱效应叠加而减小了坑间土体水平应力,进而减小开挖引起的围护结构受力和变形,但坑间土体沉降较大;基坑间距是支护结构变形的主要影响因素,两侧基坑间距位于1-2H之间（H为基坑深度）,接近1倍开挖深度一侧的叠加影响大于接近2倍开挖深度一侧。基于所配相似材料开展的基坑群模型试验具有很好的试验效果,对相关基坑群模型试验有一定参考作用。

黑尾近红鲌个体繁殖力的研究

研究了长江上游泸州地区64尾黑尾近红鱼白的个体繁殖力变动及其与雌亲体多项形态学指标的关系.结果表明黑尾近红鱼白的个体绝对繁殖力(F)平均为35726.81(4541～114356)粒;个体相对繁殖力(F/l)平均为1604.03(273.55～4462.61)粒/cm,F/mo平均为277.28(42.76～601.42)粒/g.个体绝对繁殖力(F)、个体相对繁殖力(F/l)与体长(l)、净体质量(mo)、年龄(t)、成熟系数(M)均呈显著线性正相关;相对繁殖力(F/mo)除与成熟系数(M)成直线正相关外,与其它形态指标相关不显著;个体繁殖力随丰满度(K)变化不明显.     

双倍余额递减折旧方法探讨

折旧问题是业主十分关心的技术经济问题,国外发达国家对技校更新迅速的设备采用各种快速折旧方法使设备在早期能积累较高的折旧费。为设备更新及早提供资金准备,双倍余额递减折旧 法（DDB法）是近年发展较快的一种折旧方法,在这种方法基础上发展起来的折旧转换尚有一些理论上的问题需要解决。本文在对DDB法进行分析后,重点探索了折旧转换的三种方法,为工程界、企业界更好地了解DDB法及折旧转换提供理论基础和实用途径。
