We investigate the behavior of geometric global quantum discord （GGQD） and concurrence （C） between half- spins of a mixed-three-spin （1/2, 1, 1/2） system with the Ising-XY model for which spins （1, 1/2） have the Ising interaction and half-spins （1/2, 1/2） have both XY and the Dzyaloshinskii Moriya interactions together, under the decoherence action. A single-ion anisotropy property with coefficient ζ is assumed for the spin-integer. This system which includes an analytical hamiltonian is considered at the front of an external homogeneous magnetic field B in thermal equilibrium. Finally, we compare GGQD and C and express some interesting phase flip reactions of the total quantum correlation and pairwise entanglement between spins （1/2, 1/2）. Generally, we conclude that the concurrence and GGQD have different behaviors under the phase flip channel.

This paper summarizes recent studies of particle balance in long pulse discharges, long-term erosion/deposition and hydrogen retention for carbon divertor tiles, and particle behavior in SOL and divertor plasmas related to the two foregoing topics in JT-60U. Global saturation of the particle inventory appeared in the later phase of an ELMy h-mode plasma after several long pulse discharges. As for carbon divertor tiles, erosion was dominant in the outer divertor, and deposition was dominant in the inner divertor. hydrogen isotope concentration （h＋D）/C in the deposition layer was estimated to be -0.032. The SOL plasma flow towards the inner divertor was observed at the low-field-side midplane, and influence of the E, x B drift flow from the outer divertor to the inner divertor via the private region on the divertor particle flux was evaluated to be large in the attached divertor plasmas. The preferential deposition in the inner divertor can be a consequence of these flows. For direct observation of the hydrogen molecular behavior in the divertor plasmas, hydrogen molecular line emission was measured and the fall in the emission intensity with distance from the divertor plates was reproduced by calculation with a neutral transport code and a collisional radiative modeling code.

In this work,we use the most recent publicly available type Ⅰa supernova(SNIa) compilations and h(z) data.A well formulated cosmological model based on Bianchi type Ⅰ(BI) metric is implemented in the presence of the Ricci dark energy *** the maximum likelihood technique,we estimate the present value of hubble's constant h_(0)=70.339±0.743,matter density parameter Ω_(m_(0))=0.297±0.031,anisotropy parameter Ω_(σ_(0))=-0.004 01 ± 0.001 07 within 1σ′ confidence level by bounding our derived model with recent joint Pantheon and h(z)*** have constrained the present value of the equation of state parameter as ω_(de)=-1.17 joint with the observational *** present value of the deceleration parameter of the Universe in the derived model is obtained as q_(0)=-0.749_(-0.086)^(+0.076).Transition redshift is also derived as z_(tr)~0.551 with the recent observations(Pantheon+h(z)) ***,we compare the anisotropy effects on the evolution of h(z) for the proposed model under consideration with different observational datasets.

The photon polarization parameter of the proton-deuteron radiative capture process at thermal proton energies is calculated up to leading order(LO),using pionless effective field theory(EFT).In order to make a comparative study of this model,we compare our results for the photon polarization parameter with the realistic Argonne(AV14)and Argonne v18(AV18)modern nucleon-nucleon potentials and Urbana IX or Tucson-Melbourne three-nucleon *** theoretical description of the ^(2)h(p,γ)^(3)he reaction at thermal energies is complicated by the presence of the Coulomb *** the s-wave capture contribution to the thermal energy of this reaction is ***-body currents give small but significant contributions to some of the observables in the proton-deuteron radiative capture cross section at thermal neutron *** result is in good agreement with the available experimental data and potential models'calculation at this order.

The single reference second order Brillouin-Wigner perturbation theory recently developed, which eliminates its size-extensivity error, has been generalized to state-specific, multi-reference （SS-MR）, BWPT2 providing a size-extensive correction to the electron correlation problem for systems that demand the use of a multi-reference function. Illustrative numerical tests of the size-extensivity corrections are made for widely used molecules in their ground states, which are pronounced multi-reference characteristics. We have implemented two-reference and three-reference cases for Ch2, Bh and bond breaking process in the ground states of hF molecules. The results are compared with the rigorously size-extensive methods such as the M^ller-Plesset perturbation theory, i.e., MP2, full configuration interaction （Full-CI） and allied methods using the same basis sets.

We demonstrate a Q-switched ytterbium-doped fiber laser （YDFL） using a newly developed multi-layer black phosphorous （BP） saturable absorber （SA）. The BP SA is prepared by mechanically exfoliating a BP crystal and sticking the acquired BP flakes onto a scotch tape. A small piece of the tape is then placed between two ferrules and incorporated in a YDFL cavity to achieve a stable Q-switched operation in a 1.0 μm region. The laser has a pump threshold of 55.1 mW, a pulse repetition rate that is tunable from 8.2 to 32.9 khz, and the narrowest pulse width of 10.8 μs. The highest pulse energy of 328 nJ is achieved at the pump power of 97.6 mW. Our results show that multi-layer BP is a promising SA for Q-switching laser operation.

随着信息社会的发展,通信要求从声音传输发展到电文和数字传输,将来还会发展到电视传输,也就是说,通信信息的种类正在向多样化发展,信息的总容量正在迅速增加。与此同时,所要求的传送速度也由低向高变化。分组交换网比线路交换网更适合于各种各样的通信,只不过分组网络中的设备必须要为不同的速度分别配置。本文指出,为了满足先进的和正在发展的信息传送的要求,利用LSI或处理器技术开发高速分组交换系统既合理又有效。
