A scheme for probabilistic remotely preparing N-particle d-dimensional equatorial entangled states via entangled swapping with three parties is presented. The quantum channel is composed of N - 1 pairs of bipartite d-dimensional non-maximally entangled states and a tripartite d-dimension non-maximally entangled state. It is shown that the sender can help either of the two receivers to remotely prepare the original state, and the N-particle projective measurement and the generalized Hadamard transformation are needed in this scheme. The total success probability and classical communication cost are calculated.

Objective To assess whether Community Periodontal Index (CPI) teeth and random half-mouth methods are representative of full-mouth method in gingival bleeding examination. Methods Data from 1000 untreated adults (age > 18) collected in Beijing from January 2000 to January 2001 were utilized in the analysis. Half of the subjects were examined by Gingival Bleeding Index (GBI) and the other half by Sulcus Bleeding Index (SBI). The data were sorted out and calculated according to CPI teeth and random half-mouth teeth methods. The results of the 2 methods were separately compared with those of full-mouth examination. Results There was a significant difference between CPI teeth method and full-mouth examination (P0.05), nor in diagonal half-mouth results in GBI (P>0.05) Conclusions The results of CPI teeth method on gingival bleeding could not reflect the full-mouth situation. Ipsilateral and diagonal half-mouth results can serve as a substitute for full-mouth results in SBI, while diagonal half-mouth results in GBI.

AIM To determine the influence of Smoc2 on hepatocellular carcinoma(HCC) cell proliferation and to find a possible new therapeutic target for preventing HCC *** We detected expression of Smoc2 in HCC tissues and corresponding non-tumor liver(CNL) tissues using PCR, western blot, and immunohistochemistry methods. Subsequently, we down-regulated and upregulated Smoc2 expression using siR NA and lentivirus transfection assay, respectively. Then, we identified the effect of Smoc2 on cell proliferation and cell cycle using CCK-8 and flow cytometry, respectively. The common cell growth signaling influenced by Smoc2 was detected by western blot assay. RESULTS The expression of Smoc2 was significantly higher in HCC tissues compared with CNL tissues. Overexpression of Smoc2 promoted HCC cell proliferation and cell cycle progression. Down-regulation of Smoc2 led to inhibition of cell proliferation and cell cycle progression. Smoc2 had positive effect on ERK and AKT *** Smoc2 promotes the proliferation of HCC cells through accelerating cell cycle progression and might act as an anti-cancer therapeutic target in the future.

A new signal is proposed for the colour reconnection in the hadronic decay of W^(+) W^(-) in e^(+)e^(-) *** Pythia Monte Carlo it is shown that factorial correlators for W^(+) and W^(-) without colour reconnection are almost identical to unity,while those for the cases with colour reconnection fall down approximately linearly in the loglog plot-This signal,being based on the tactorial correlator,is more sensitive than the ones using only averaged quantities.

Poly（butadiene-co-styrene） copolymer/multi-walled carbon nanotubes （SB-MWNTs） nanocomposites are prepared via termi- nating anionically synthesized living poly（butadiene-styryl）lithium with acyl chlorides on the MWNTs, which obtained from the carboxylation and acylation of the MWNTs. Results from the characterization of the SB-MWNTs nanocomposites, including its soluble in solvent, UV-vis and TEM of the dissolved samples, TGA and SEM of nanocomposites are presented and discussed respectively. MWNTs treated by SB can be easily distributed in the SBR （styrene-butadiene rubber） matrix.

A porous Pb foam was fabricated electroche- mically at a copper substrate and then used as the cathode for the electroreduction of COE. The surface morphology and composition of the porous Pb electrode was characterized by scanning electron microscopy, X-ray diffraction, transmission electron microscopy and selected area electron diffraction. The honeycomb-like porous structure was composed of needle-like Pb deposits. Cyclic voltammetry studies demonstrated that the porous Pb electrode had better electrocatalytic performance for the formation of formic acid from CO2 compared with a Pb plate electrode. The increase in current density was due to the large surface area of the porous Pb electrode, which provides more active sites on the electrode surface. The improved formic acid selectivity was due to the morphol- ogy of the roughened surface, which contains significantly more low-coordination sites which are more active for CO2 reduction. The highest current efficiency for formic acid was 96.8% at - 1.7 V versus saturated calomel electrode at 5℃. This porous Pb electrode with good catalytic abilities represents a new 3D porous material with applications for the electroreduction of CO2.

The elastic modulus of Fe72.5Ga27.5 magnetostrictive alloy is determined by testing ac impedance resonance frequency and first-principle calculations. The observed elastic modulus is 90.2 GPa for a directionally solidified sample and 103.4 GPa for a water-quenched sample tested in a dc magnetic field of 32. 7mT without compressive pre-stress. The bulk modulus by first-principles calculation is 179.3GPa which is basically consistent with the experimental result. The elastic modulus first increases and then decreases with increasing dc magnetic field, attributed to magnetostriction occurrence in the Fe72.5Ga27.5 alloy. The elastic modulus increases with increasing compressive pre-stress, resulting from the initial magnetic states change under the applied compressive pre-stress. The elastic modulus increases match well with the improved magnetostriction after quenching.
