Polybrominated diphenyl ethers(PBDEs)are a group of aromatic organic bromine compounds,which have been used in a broad array of polymeric materials(plastics,foams,resins,and adhesives)as brominated flame *** are used in commercial and household products,including textiles,electronic equipment,airplanes,and automobiles,especially in China and the USA,because they are inexpensive with excellent flame-retardant effects[1].During the past decade,over 14,000 tonnes of PBDEs have entered the market,and have become ubiquitous environmental contaminants[2].

A novel rational protocol to share two arbitrary qubits among multiple parties is investigated in this paper. First, the protocol is presented, which is learned from Li et al.’s protocol. Second, the utility,security, correctness, fairness, Nash equilibrium, and Pareto optimality of our scheme are discussed in detail,where the utility, correctness, and fairness of rational quantum state sharing protocols are creatively given because the agent who recovers the state plays a different and more important role. Another important point is that assumptions about our protocol are more practical and suitable than existing protocols.

In this paper, close-coupling method was applied to the He-H2 （D2,T2） system, and the first vibrational excitation cross sections of ＇00-10, 00-12, 00-14, 00-16＇ at different incident energy have been calculated. By analyzing the ditferences of these partial wave cross sections, this paper have obtained the change rules of the partial wave cross sections with increases of quantum number, and with change of reduced mass of system. Based on the calculation, influence on the partial wave cross sections brought by the variations in the reduced mass of systems and in the relative kinetic energy of incident atoms is discussed.

The pleiotropic drug resistance（PDR） sub-family of adenosine triphosphate（ATP）-binding cassette（ABC） transporter had been reported to participate in diverse biological processes of plant. In this study, we cloned three novel PDR genes in Fusarium head blight（FHB） resistant wheat cultivar Ning 7840, which were located on wheat chromosomes 6A, 6B and 6D. In phylogeny, these genes were members of cluster I together with Ae PDR7 and Bd PDR7. Subcellular localization analysis showed that Ta PDR7 was expressed on the plasmalemma. The quantitative real time PCR（RT-PCR） analysis showed that this gene and its probable orthologues in chromosomes 6B and 6D were both up-regulated sharply at 48 h after infected by Fusarium graminearum and trichothecene deoxynivalenol（DON） in spike. When knocking down the transcripts of all Ta PDR7 members by barely stripe mosaic virus-induced gene silencing（BSMV-VIGS） system, it could promote the F. graminearum hyphae growth and made larger pathogen inoculation points in Ning 7840, which suggested that Ta PDR7 might play an important role in response to F. graminearum. Although salicylic acid（SA）, methyl jasmonate（Me JA） and abscisic acid（ABA） had been reported to possibly regulate wheat FHB resistance, here, we found that the three members of Ta PDR7 were negatively regulated by these three hormones but positively regulated by indoleacetic acid（IAA）.
