The optimal thresholds and neighboring window sizes are determined for every subband in the wavelet domain using Stein's unbiased risk estimate, and NeighShrink is also extended from orthogonal wavelet transforms to dual-tree complex wavelet transforms in this paper.

该文运用Stein的无偏风险估计，在小波域每一个子带为NeighShrink方法确定一个最优的阈值和邻域窗口，并将NeighShrink方法从正交的小波变换推广到对偶树复数小波变换。

The results indicate that if all the investors all full rational,the equilibrium price,whether using close call auction or open call auction,is the unbiased estimator of the risky assets true value.

研究结论表明，若所有的投资者都是理性的，无论采用封闭式集合竞价还是开放式集合竞价，那么均衡价格均是风险资产真实价值的无偏估计量。

The utilisation of isolator technology to minimise human interventions in processing areas may result in a significant decrease in the risk of microbiological contamination of aseptically manufactured products from the environment.

The paper probed into the following questions :the scope of applying the waiving of right; the difference between life insurance and property insurance in applying the right-waiving rules when an insurant has no insurable interest; that right-waiving and estoppel are only applied when the insured claim the insurance money; that under the good faith principle, disclaiming and estoppel may be applied when the insurent has no insurable interest.

Three simultaneous reports involving more than 32,000 participants uncovered four new diabetes-associated gene variants, bringing to 10 the number of known non-Mendelian genetic risk factors for type 2 diabetes.

这些差异是2007年十几个研究项目的关键，研究人员在这些被称为基因组范围关联研究(genome-wide association studies)中比较几千位患病或无病个体的DNA，来确定哪些小的基因差异带来疾病风险。

"Here we have two variants that have no impact on pigmentation and only affect the risk of basal cell carcinoma," Kari Stefansson, Decode's chief executive, who led the study, said in a telephone interview.
