基因编辑婴儿的伦理、法律和社会蕴含

 同试管婴儿、克隆人、商业化代孕、干细胞治疗等医疗新技术引发的伦理争议相比，贺建奎基因编辑婴儿事件引发的关注更大、社会反响更为猛烈。探讨贺建奎基因编辑婴儿事件引发国际国内热议的原因，讨论了基因编辑婴儿的伦理、法律和社会蕴含。建议明确界定基因编辑技术的适用对象和范围，建立健全新型医疗技术临床应用的伦理审查和监管体系，提升全社会的伦理意识。

Path integral quantization corresponding to the deformed Heisenberg algebra

In this paper, the deformation of the Heisenberg algebra, consistent with both the generalized uncertainty principle and doubly special relativity, has been analyzed. It has been observed that, though this algebra can give rise to fractional derivative terms in the corresponding quantum mechanical Hamiltonian, a formal meaning can be given to them by using the theory of harmonic extensions of function. Depending on this argument, the expression of the propagator of the path integral corresponding to the deformed Heisenberg algebra, has been obtained. In particular, the consistent expression of the one dimensional free particle propagator has been evaluated explicitly. With this propagator in hand, it has been shown that, even in free particle case, normal generalized uncertainty principle and doubly special relativity show very much different result.     

非线性叠加效应研究

对非线性叠加效应进行了研究,在Toda晶格中,当两孤立子运动方向相同时,其速度波的振幅的极大值是原来两波振幅之差,两波叠加的最大振幅是原来两波振幅之和。这些结果跟线性波叠加情况是完全不同的。
