Efficient symmetric multiparty quantum state sharing of an arbitrary m-qubit state

We present a scheme for symmetric multiparty quantum state sharing of an arbitrary $m$-qubit state with $m$ Greenberger-Horne-Zeilinger states following some ideas from the controlled teleportation [Phys. Rev. A \textbf{72}, 02338 (2005)]. The sender Alice performs $m$ Bell-state measurements on her $2m$ particles and the controllers need only to take some single-photon product measurements on their photons independently, not Bell-state measurements, which makes this scheme more convenient than the latter. Also it does not require the parties to perform a controlled-NOT gate on the photons for reconstructing the unknown $m$-qubit state and it is an optimal one as its efficiency for qubits approaches the maximal value.Comment: 6 pages, no figures; It simplifies the process for sharing an arbitrary m-qubit state in Phys.

Multiparty quantum secret sharing with pure entangled states and decoy photons

We present a scheme for multiparty quantum secret sharing of a private key with pure entangled states and decoy photons. The boss, say Alice uses the decoy photons, which are randomly in one of the four nonorthogonal single-photon states, to prevent a potentially dishonest agent from eavesdropping freely. This scheme requires the parties of communication to have neither an ideal single-photon quantum source nor a maximally entangled one, which makes this scheme more convenient than others in a practical application. Moreover, it has the advantage of having high intrinsic efficiency for qubits and exchanging less classical information in principle.Comment: 5 pages, no figure

Efficient high-capacity quantum secret sharing with two-photon entanglement

An efficient high-capacity quantum secret sharing scheme is proposed following some ideas in quantum dense coding with two-photon entanglement. The message sender, Alice prepares and measures the two-photon entangled states, and the two agents, Bob and Charlie code their information on their photons with four local unitary operations, which makes this scheme more convenient for the agents than others. This scheme has a high intrinsic efficiency for qubits and a high capacity.Comment: 5 pages, no figures. A inappreciable error is correcte

High level expression of human epithelial β-defensins (hBD-1, 2 and 3) in papillomavirus induced lesions

BACKGROUND: Epithelial defensins including human β-defensins (hBDs) and α-defensins (HDs) are antimicrobial peptides that play important roles in the mucosal defense system. However, the role of defensins in papillomavirus induced epithelial lesions is unknown. RESULTS: Papilloma tissues were prospectively collected from 15 patients with recurrent respiratory papillomatosis (RRP) and analyzed for defensins and chemokine IL-8 expression by quantitative, reverse-transcriptase polymerase chain reaction (RT-PCR) assays. HBD-1, -2 and -3 mRNAs were detectable in papilloma samples from all RRP patients and the levels were higher than in normal oral mucosal tissues from healthy individuals. Immunohistochemical analysis showed that both hBD-1 and 2 were localized in the upper epithelial layers of papilloma tissues. Expression of hBD-2 and hBD-3 appeared to be correlated as indicated by scatter plot analysis (r = 0.837, p < 0.01) suggesting that they were co-inducible in papillomavirus induced lesions. Unlike hBDs, only low levels of HD5 and HD6 were detectable in papillomas and in oral mucosa. CONCLUSION: Human β-defensins are upregulated in respiratory papillomas. This novel finding suggests that hBDs might contribute to innate and adaptive immune responses targeted against papillomavirus-induced epithelial lesions

Study on the immunogencity of poly(D,L-lactide-coglycolide) (PLGA) microspheres-encapsulated vaccine preparation against Stenotrophomonas maltophilia infection in channel catfish (Ictalurus punctatus)

The purpose of the experiment is to study the poly(D,L-lactide-co-glycolide) (PLGA) microspheres of coated in fish vaccine formulations. In this study, we prepared Pseudomonas bacteria widowed raise PLGA microspheres vaccine by double emulsion evaporation maltophilia. It was prepared to support the completion of the Stenotrophomonas maltophilia oligonucleotide PLGA microspheres vaccine through injection as well as oral and immersion in three ways inoculated based on body weight (100 ± 5g) of channel catfish, each has five immunization groups, of which three group were different doses of the immune group, the other two groups were not coated with S. maltophilia raising vaccination with inactivated Aeromonas group and the control group. During the 0, 28 and 56th day, the immunization group were processed in same way. Collection of blood and measuring of immune-related indicators at 0, 7th, 21st, 35th and 49th day were carried out. At the 63th day, 0.2 ml of each fish at the concentration of 1 × 109 cfu/ml of Stenotrophomonas widow raising a single cell suspension of viable bacteria was injected into the Channel catfish. Continuous observation and recording of the results of each group shows that the experimental vaccine preparation of PLGA microspheres encapsulation efficiency was 88.93%, the immunization route vaccine group versus those in saline control group significantly enhance the phagocytic activity of white blood cells, serum lysozyme, complement C3, serum protein content and antibody IgM levels. Channel catfish immunized by injection were challenged with live S. maltophilia, the relative survival rates of group 3 was 9.16% higher than group 5; however group 1 was 15% lower than group 5 ,group 2 was 1.67%. Another five groups immunized by oral vaccination were challenged with S. maltophilia, the relative survival rates of group 1 to group 3 were 43.33, 65 and 75%, but group 5 was only 6.68%. Conclusively, injection and oral vaccination of Stenotrophomonas widow raising Aeromonas vaccine PLGA microspheres in Channel catfish has a good immune protective effect, while the immersion of the protective effect of various immunization groups was not obvious.Keywords: Stenotrophomonas maltophilia, poly(D,L-lactide-co-glycolide), Ictalurus punctatus, vaccin

Study on muon anomalous magnetic dipole moment in BLMSSM via the mass insertion approximation

There are 4.2 $\sigma$ deviations between the updated experimental results of muon anomalous magnetic dipole moment (MDM) and the corresponding theoretical prediction of the Standard Model (SM). We calculate the muon MDM in the framework of the MSSM extension with local gauged baryon and lepton numbers (BLMSSM). In this paper, we discuss how the muon MDM depends on the parameters in the BLMSSM in detail within the mass insertion approximation. Among the many parameters, $\tan{\beta}$, $g_L$, $m_{\lambda_L}$ and $\mu_H$ are more sensitive parameters. Considering the experimental limitations, our best numerical result of $a^{BL}_{\mu}$ is around $2.5 \times 10^{-9}$, which can well compensate the departure between the experiment data and SM prediction

Study lepton flavor violation Bd→li±lj∓B_d\rightarrow{{l_i}^{\pm}{l_j}^{\mp}} within the Mass Insertion Approximation

We study lepton flavor violating (LFV) decays $B_d\rightarrow{{l_i}^{\pm}{l_j}^{\mp}}$($B_d\rightarrow e{\mu}$, $B_d\rightarrow e{\tau}$ and $B_d\rightarrow {\mu}{\tau}$) in the $U(1)_X$SSM, which is the $U(1)_X$ extension of the minimal supersymmetric standard model(MSSM). The local gauge group of $U(1)_X$SSM is $SU(3)_C\times SU(2)_L \times U(1)_Y \times U(1)_X$. These processes are strictly forbidden in the standard model(SM), but these LFV decays are a signal of new physics(NP). We use the Mass Insertion Approximation(MIA) to find sensitive parameters that directly influence the result of the branching ratio of LFV decay $B_d\rightarrow{{l_i}^{\pm}{l_j}^{\mp}}$. Combined with the latest experimental results, we analyze the relationship between different sensitive parameters and the branching ratios of the three processes. According to the numerical analysis, we can conclude that the main sensitive parameters and LFV sources are the non-diagonal terms of the slepton mass matrix

Theoretical Corrections of RDR_D and RD∗R_{D^*}

$R_{D^{(*)}}$ is the ratio of branching ratio $\overline{B} \rightarrow D^{(*)}\tau\overline{\nu}_{\tau}$ to $\overline{B} \rightarrow D^{(*)}l\overline{\nu}_{l}$. There is a gap of $2\sigma_{exp}$ or more between its experimental value and the prediction under the standard model(SM). People extend the MSSM with the local gauge group $U(1)_X$ to obtain the $U(1)_X$SSM. Compared with MSSM, $U(1)_X$SSM has more superfields and effects. In $U(1)_X$SSM, we research the decays $\overline{B} \rightarrow D^{(*)}l\overline{\nu}_{l}$ and calculate $R_{D^{(*)}}$. The obtained numerical results of $R_{D^{(*)}}$ are further corrected under $U(1)_X$SSM, which is much better than the SM predictions. After correction, the theoretical value of $R_{D^{(*)}}$ can reach in one $\sigma_{exp}$ range of the averaged experiment central value
