He accepted a version of the inheritance of acquired characteristics (which after Darwin's death came to be called Lamarckism), and Chapter V discusses what he called the effects of use and disuse; he wrote that he thought "there can be little doubt that use in our domestic animals strengthens and enlarges certain parts, and disuse diminishes them; and that such modifications are inherited", and that this also applied in nature.

他接受的一个形式是获得性状遗传(在达尔文去世后被称为拉马克主义)。第五章讨论他所说的使用或废弃的影响;他写道,他认为"毫无疑问,在我们的家养动物中,使用加强和扩大某些部分,而废弃使它们变小;而这种修改被继承",而且这也适用于自然界。

The strongest evidence for linkage in 147 families with late-onset PD was on chromosome 17 near the tau gene -- previously shown to be involved in other neurodegenerative diseases including frontotemporal dementia with parkinsonism and progressive supranuclear palsy.

147个患有迟发型帕金森氏症的家庭在遗传研究中被发现,该病与17号染色体上的tau基因有关联。以前tau基因被认为与其它的神经变性疾病有关,如伴有震颤麻痹的额颞型痴呆以及进行性核上性麻痹有关。

Meme, considered to be passed on by monogenetic unit, is defined as an element of culture.

After some generations the population diversity would be greatly reduced and the algorithm might lead to a premature convergence to a local optimum. To circumvent these shortcomings, the chaotic dynamic system is introduced in the studies of chemometric algorithms. The chaotic mapping itself is very sensitive to the initial state in a manner similar to the statistical randomness but with its underlying patterns appearing to be phantasmagoric in a deterministic style.

神经网络是一个优异的非线性建模工具,但其突出的缺点就是潜在的预收敛到局部最优点或过拟合导致的错误预报模式;遗传算法用于优化过程其目的是为了避免陷入局部最优点,但事实上由于在传统遗传算法的进化过程中只有少数最好的成员被保留下来用于产生子代成员,经过一定代数的进化后群体成员的多样性就会显著下降,也很可能过早收敛到局部最优点。

Begg argues that all risk factors for breast cancer are overrepresented in incident cases of breast cancer, so that a sample of women who have been diagnosed with breast cancer and who are identified as mutation carriers are more likely to have other breast cancer risk factors than similar mutation carriers who are disease-free.

Dr。 Begg认为,所有的乳腺癌危险因子在乳腺癌病例中都被高估,所以一些已经被诊断为乳腺癌,且确认是某种基因突变的携带者妇女,比起具有相似的遗传突变的健康携带者,更可能是其他乳腺癌的危险因子导致疾病发生。
