In the design and construction process of Next Generation Internet, it is important to identify the source of each IP packet forwarding accurately, especially for the support of precise fine-grained management,control, traceability and improving the trustworthiness of the Internet. This paper designed a scalable Network Identity(NID) scheme for the Internet users, proposed NIDTGA(Network Identity and Time Generated Address), an IPv6 address generation algorithm embedded NID and time information, then designed and implemented an IPv6 address generation and traceback system based on NIDTGA. The design of NIDTGA, which reflects the length, time and owner attributes of the IP address, can be a good support to ADN(Address Driven Network). At the same time, by embedding the key elements of user identity and time in the IPv6 address,and by taking into account both the traceability and privacy, NIDTGA can provide a technical basis for the establishment of the network trust mechanism, and achieve the traceability of security event.

The electronic properties of van der Waals(vd W) structures can be substantially modified by the moiré superlattice potential, which strongly depends on the twist angle among the compounds. In twisted bilayer graphene(TBG), two lowenergy Van Hove singularities(VHSs) move closer with decreasing twist angles and finally become highly non-dispersive flat bands at the magic angle(~1.1°). When the Fermi level lies within the flat bands of the TBG near the magic angle,Coulomb interaction is supposed to exceed the kinetic energy of the electrons, which can drive the system into various strongly correlated phases. Moreover, the strongly correlated states of flat bands are also realized in other graphene-based vd W structures with an interlayer twist. In this article, we mainly review the recent scanning tunneling microscopy(STM)advances on the strongly correlated physics of the magic-angle TBG(MATBG) and the small-angle twisted multilayer graphene. Lastly we will give out a perspective of this field.

N-ethyl-N-nitrosourea （ENU） mutagenesis has led to the elucidation of several regulator genes for melanocyte and skin development. here we characterized a mutant from ENU mutagenesis with similar phenotype as that of Splotch mutant, including exencephaly, spina bifida and abnormal limbs in homozygotes as well as white belly spotting and occasionally loop-tail in heterozygotes. This novel mutant was named as SpxG. Through genome-wide linkage analysis in backcross progenies with microsatellite markers, the SpxG was confined to a region between DIMIT415 and DIMIT7 on chromosome 1, where notable Pax3 gene was located. Direct sequencing revealed that SpxG carried a nucleotide A894G missense transition in exon 6 of Pax3 gene that resulted in Asn to Asp substitution at amino acid 269 within the highly-conserved homeodomain （HD） DNA recognition module, which was the first point mutation found in this domain in mice. This N269D mutation impaired the transactivation capacity of Pax3 protein, but exerted no effect on Pax3 protein translation. The characterization of the new mutation expanded our understanding the transactivation and DNA-binding structure of Pax3 protein.

Fluorescently labeled universal primer directed differential display polymerase chain reaction technique (FLUPD-DD-PCR), an improved DD-PCR, is reported for the study of mRNA expression of glioma cells cultured with the serum starvation. The fluorescently labeled universal primer (FLUP) facilitates analysis of PCR products on an auto-sequencer. Compared with the traditional DD-PCR, FLUPD-DD-PCR has advantages of separation of target bands and measurement of mRNA expression quantitatively by adopting Cy5-labeled universal primer. And then the silver staining method has been used to recover the bands for use as template in re-pcr. in this study, 4 differential ESTs, of which 3 are novel ESTs, have been obtained. This work indicates some special novel genes, which can be induced to express under serum absent condition, are involved in coping with serum starvation stress on glioma cells growth.
