Molecular biological analysis of remains from Jiangjungou Cemetery in Inner Mongolia

The 364-bp nucleotide sequence in hypervariable region I (HVRI) of mitochondrial DNA is successfully amplified from 9 out of 11 individuals of an ancient population buried in the Jiangjungou Cemetery in Inner Mongolia dated back to the Warring States Period in China. Nine fragments with different variations are obtained. A phylogenetic tree and a multidimensional scaling (MDS) plot are constructed using mtDNA sequences from the ancient population and several modern Asian populations. The results show that ancient population shares a closer genetic relationship with East Asian populations than with North and Central Asian populations. The genetic and historical evidence raise the possibility that the population might be the immigrants from Zhongyuan area, sent by the King Wuling of Zhao State to guard the nation against the attack from Huns.

An efficient method for parallel CRC automatic generation

The State Transition Equation (STE) based method to automatically generate the parallel CRC circuits for any generator polynomial or required amount of parallelism is presented. The parallel CRC circuit so generated is partially optimized before being fed to synthesis tools and works properly in our LAN transceiv-er. Compared with the cascading method, the proposed method gives better timing results and significantly re-duces the synthesis time, in particular.

Deterministic secure quantum communication and authentication protocol based on three-particle W state and quantum one-time pad

Three-particle W states are used as decoy photons, and the eavesdropping detection rate reaches 63 %. The positions of decoy photons in information sequence are encoded with identity string ID of the legitimate users. Authentication is implemented by using previously shared identity string. State 丨φ^- ） is used as the carrier. One photon of 丨φ^-） is sent to Bob; and Bob obtains a random key by measuring photons with bases dominated by ID. The bases information is secret to others except Alice and Bob. Both the eavesdropping detection based on three-particle W state and the secret ID ensure the security of the protocol. Unitary operations are not used.     

A brief introduction to National Laboratory for Superconductivity, Institute of Physics, Chinese Academy of Sciences

In line with the rapid development of research on high-temperature superconductors, the establishment of a National Laboratory for Superconductivity in the Institute of Physics, the Chinese Academy of Sciences (CAS) was ratified by the State Commission of Development & Planning (SCDP) in 1987. The preparations were started in 1988, and in April of 1991,the Laboratory was finally established, accepted and listed as a National Laboratory open to both domestic and foreign researchers. After the joint appraisal and acceptance by the National Natural Science Foundation of China and the Ministry of Science & Technology, it was honored with a title of the Outstanding National Laboratory in 2000.     

Trajectory tracking control of quantum systems

For quantum state trajectory tracking of density matrix in Liouville equation of quantum systems,with the help of concept in quantum system control,one can apply unitary transformation both to controlled system and free-evolutionary target system such as to change the time-variant and non-stationary target system into a stationary state.Therefore,the quantum state trajectory tracking problem becomes a steering one.State steering control law of the system transformed is designed by means of the Lyapunov stability theorem.Finally,numerical simulation experiments are given for a five-level energy quantum system.The comparison analysis of original system’s trajectory tracking with other method illustrates the advantage in control time of the method proposed.     

A Stylistic Study on Barack Obama’s Presidential Victory Speech

Higher-level foreign languages learners have always paid much attention to English public speeches, especially presidential speeches in the United State. The present paper concentrates on the study of Barack Obama’s presidential victory speech from the perspective of literary stylistics based on the levels of lexical, syntax, rhetorical devices, etc,with the aim to study the stylistic features of the speech so as to have a better appreciation of Obama’s art of public speaking and the meaning of the speech. ...
