	Abstract:A tripartite scheme with a pair of Bell states has been put forward recently byZhang and Cheung for remotely sharing two restricted sets of operations in a deterministic manner[ J. Phys. B extbf{44} (2011) 165508]. In this paper, a generalized scheme is presented, whichis applicable for another six restricted sets besides the original two. Features about scheme security,sharer symmetry, fulfillment determinacy and experimental feasibility are revealed. Moreover, the schemeis discussed from the aspects of quantum and classical resource consumption, necessary operation complexityand efficiency.

	Abstract:We propose an approach for an optical qubit rotation in the negatively chargednitrogen-vacancy (NV) center in diamond. The qubit is encoded in the grounddegenerate states at the relatively low temperature limit. The basic idea ofthe rotation procedure is the non-Abelian geometric phase in an adiabatic passage,which is produced by the nonadiabatic transition between the two degenerate darkstates. The feasibility is based on the success of modeling the NV center as anexcited-doublet four-level atom.

	Abstract:The uncertainty of existed experimental energy loss of hydrogen ions in low energy region is rather large. However it is always a challenge to measure the energy loss in low energy region in experiment. In this work, the projected range of ions in thick target was used to investigate the electronic energy loss of H$^+$ ions in single crystal silicon. Firstly, the single crystal silicon targets were implanted by H$^+$ ions with energies of 10, 25, 80, 90 keV in random direction at room temperature. Then, the depth profiles of implanted hydrogen were measured by resonance nuclear reaction $^{1}$H($^{15}$N,$gammalpha$)$^{12}$C analysis. The projected ranges of as-implanted H$^+$ ions with different energies were obtained from the depth profiles because the implanted hydrogen showed limited mobility in silicon. Finally, the electronic energy loss of H$^+$ in silicon was derived from the projected range data with a code based on Projected Range Algorithm (PRAL). The result was roughly consistent to electronic energy loss of SRIM. This work provided an experimental method to exactly detect the energy loss of hydrogen ions in low energy where the hydrogen implanted showed limited mobility.

	4. Weak Gravity Conjecture and Holographic/Agegraphic Dark Energy

	Abstract:A criterion that should be satisfied in the inflation andquintessence models has been motivated from the weak gravityconjecture (WGC) by Huang. However, it is found that the criterionis inconsistent with the holographic dark energy (HDE) and newagegraphic dark energy (NADE) models. In the note, we firstly showthat in the HDE and NADE models the criterion should be be replacedrespectively by two new criterions. Secondly, we apply the newcriterions indicated by WGC to survey the two models. We find thatthe contradiction between WGC and the NADE model is removed when thenew criterion is used. In the HDE model, we find the effects of thespatial curvature and the interaction should be considered in orderto match the new criterion.

	Abstract:For ghost imaging (GI), pursuing high resolution images and short acquisition times required for reconstructing images are always two main goals. We report an image reconstruction algorithm of compressive sensing (CS) called adaptive inverse scale space (aISS) method to recover ghost images. By AISS method, ghost imaging with a good signal-to-noise ratio and short acquisition times is achieved. The relationship between ghost imaging and compressive sensing is also discussed in this paper.

	Abstract:The strain effect on the graphene-encapsulated Au nanoparticles is investigated. A Finite-Element calculation is performed to simulate the strain distribution and morphology of the monolayer and multilayer graphene-encapsulated Au nanoparticles, respectively. It can be found that the inhomogeneous strain and deformation are enhanced with the increasing shrinkage of the graphene shell. Moreover, the strain distribution and deformation are very sensitive to the layer number of the graphene shell. For the mono- and bi-layer graphene-encapsulated Au nanoparticles, the dramatic shape transformation can be observed. However, with increasing the graphene thickness further, there is hardly deformation for the encapsulated Au nanoparticles. These simulated results indicate that the strain and deformation can be designed by the graphene layer thickness, which provides an opportunity to engineer the structure and morphology of the graphene-encapsulated nanoparticles.

	Abstract:We investigate transmission coefficients through quantum well andquantum superlattice on topological insulator surfaces. The quantumwell or superlattice is not constituted by general electronicpotential barriers but Fermi velocities barriers which originates inthe different topological insulator surfaces. It is found thatelectron resonant modes can be renormalized by quantum well and moreobviously by quantum superlattice. The depth and width of a quantumwell and superlattice, the electron incident angle, and the Fermi energy can be used to effectively tune the electronresonant modes, and in particular the number $N$ of periodicstructures for a superlattice can further strengthenthese regulating effects. These results imply a substitute device toselect and regulate electron propagating modes in topologicalinsulator surface. Finally, we also study the total conductance andFano factor through quantum well and quantum superlattice. Differentfrom the reported before, the suppression factors $0.4$ inconductance and $0.85$ in Fano factor are observed in quantum well,while the transport for quantum superlattice shows strong oscillatingbehaviors at small energy and reaches the same saturated values asthe case of quantum well at large enough energy.

	Abstract:Boussinesq-Burgers (B-B) equations describe the long-wavepropagation in shallow water and are potentially applicable to theharbor and coastal designs. By virtue of the matrix extension in theWronskian technique, some exact solutions of the B-B equationsare obtained, such as the soliton, rational and periodic solutions.Solitonic interactions are discussed. Elastic-inelastic-interactioncoexistence is hereby observed, in addition to the previously-seenpure inelastic or elastic interactions.

	Abstract:With industrial and economic development, global environmental pollution is worsening. Therefore, preparation of high photocatalytic activity Cd-doped ZnO nanoflowers could solve this problem. The ZnO nanoflowers doped with cadmium ions have been prepared by a hydrothermal method and the photocatalytic activities of the asprepared samples for the rhodamine B (RhB) photo-degradation were investigated. The products were characterized by multiple techniques: X-ray diffraction (XRD), scanning electron microscopy (SEM), energy-dispersive X-ray analysis (EDS), photoluminescence (PL) spectroscopy, UV-visible spectroscopy and so on. The results manifested the crystal quality of the samples were much weakened on increasing doping concentration from 5 to 20 at%. Then the absorption edge and the UV emission peak of the Cd-doped ZnO nanoflowers shifted to the red. It was also found that the band gap decreased linearly from 3.24 eV to 3.06 eV. Especially, the 5% Cd-doped ZnO nanoflowers showed the highest photocatalytic activity which increased the rate of photocatalytic degradation of rhodamine B (RhB) up to 98% after 3 h of irradiation. So the photocatalytic activities of the 5 percent Cd-doped ZnO nanoflowers are higher than other samples.

	10. Simulation and experiment of coupling a fundamental-mode laser into a single-mode fiber

	Abstract:The theoretical and experimental study of an optical coupling system for coupling a fundamental-mode laser into a single-mode fiber is presented. Two different methods are introduced to design the system. First, the software of Tracepro based on geometric optics is used to design the proper optical coupling system. Second, the method of q parameter and ABCD law is employed to provide the optimal parameters of the optical coupling system. A simple optical coupling system is employed to couple the He-Ne 632.8 nm laser into a 9/125 μm single-mode fiber. A high coupling efficiency of 90% is obtained. Comparing these theoretical results with the experimental results, it is known that the method of q parameter and ABCD law with lens thickness considered is more appropriate to designing the coupling system because the theoretical coupling efficiency is very close to the experimental value. The further calculation indicates that the optical coupling system used in the experiment is suitable for most of fundamental-mode lasers with different wavelengths, waist sizes and M2 factors.
