In this paper we study the entanglement in a two-qubit spin in the XYZ model, and teleport a two-qubit entangled state using this spin chain in the condition of the thermal equilibrium as a quantum channel. We investigate the effects of the interaction of z-component Jz, the inhomogeneous magnetic field b, the anisotropy γ and the temperature T on the entanglement and fidelity. In order to characterize the quality of the teleported state, we research the average fidelity Fα. High average fidelity of the teleportation is obtained when the temperature is very low. Under some condition, we also find that when innomogeneity increases to a certain value, the average fidelity can exhibit a larger revival than that for less values of b.

In this scheme, N non-maximally entangled particle pairs are used as quantum channel to teleport an unknown N-particle entangled GHZ state via entanglement swapping. In order to realize this teleportation, the sender Alice operates Bell-state measurement on particles belonging to herself. Then she informs the results to the receiver Bob through classical communication. According to the results, Bob operates corresponding transformation to reconstruct the initial state. The advantage of this scheme is that it needs only one common unitary matrix for Alice＇s different results, which has a more general meaning. As a special case, teleporting an unknown three-particle entangled GHZ state is proposed.

In this paper, quantum teleportatlon of one-to-many using （n ＋1）-particle entanglement is presented. If the sender （Alice） wants to transmit an unknown quantum state to a distant receiver （Bob）, similar to the previous schemes, Alice performs Bell-state measurement on particles belonging to herself and informs the receiver the results through the classical channel. After that, it needs to perform the Hadamard operation on the other （n - 1） particles and measure them as well. With the aid of the measurement results, Bob can operate a corresponding unitary transformation on his particle to reconstruct the original state. Of course, the reconstruction may realize at either location of n, but it cannot realize at all locations at the same time.

Background： Dermatomyositis （DM） and polymyositis （PM） are common inflammatory myopathies whose immunopathogenic mechanisms remain poorly understood. The NOD-like receptor family, pyrin domain containing 3 （NLRP3） inflammasome is a type of cytoplasmic multiprotein inflammasome and is responsible for the activation of inflammatory reactivations. Responding to a wide range of exogenous and endogenous microbial or sterile stimuli, NLRP3 inflammasomes can cleave pro-caspase- 1 into active caspase- 1, which processes the pro-infammatory cytokines pro-interleukin （IL）-1 β and pro-IL-18 into active and secreted IL-1β and I L-18. The NLRP3 inflammasome is implicated in infectious and sterile inflammatory diseases. However, it remains unclear whether it is involved in the pathogenesis of DM/PM, which we aim to address in our research. Methods： In this study, 22 DM/PM patients and 24 controls were recruited. The protein and RNA expression of IL-113, IL-18, NLRP3, and caspase-1 in serum and muscle samples were tested and compared between the two groups. Results： The serum IL-1 β and IL-18 levels were significantly higher in DM/PM patients than those in the controls by enzyme linked immunosorbent assay （EL1SA, DM vs. control, 25.02 ± 8.29 ng/ml vs. 16.49 ± 3.30 ng/ml, P 〈 0.001 ; PM vs. control, 26.49±7.79 ng/ml vs. 16.49 ± 3.30 ng/ml, P 〈 0.001）. Moreover, the real-time quantitative reverse transcription-polymerase chain reaction （qRT-PCR） showed that DM/PM patients exhibited higher RNA expression of IL-lβ, IL-18, and NLRP3 in the muscle （for IL-1 β, DM vs. control, P 0.0012, PM vs. control, P = 0.0021 ; for IL- 18, DM vs. control, P = 0.0045, PM vs. control, P 0.0031 ; for NLRP3, DM vs. control, P = 0.0017, PM vs. control, P 0.0006）. Moreover, the protein expression of NLRP3 and caspase- 1 in muscle samples of DM/PM patients were also significantly elevated compared to that in the muscles of the controls. Conclusions： Our findings demonstrate that the NLRP3 inflammasome is im

Under the sliding bearing support for the rotor-bearing system, the dynamic model of a rotor-bearing system is established under the action of non-linear oil film force. The rotor-bearing system has been studied by the application of nonlinear dynamics theory, and the system＇s response was obtained by the numerical integration approach. The effects of eccentricity, speed, lubricant viscosity, radius gap, bearing length and journal radius on the system＇s response have been studied by using an amplitude-frequency curve, three-dimensional spectrum and bifurcation, which provides a theoretical basis for the diagnosis of the oil whirl fault effectively in the rotor-bearing system supported by a sliding bearing.

为了提高根据遥测数据进行卫星故障诊断的速度与精度,提出了集成多信号模型诊断Agent、模糊诊断Agent以及专家系统诊断Agent等多Agent监测与诊断系统。多信号模型诊断Agent,采用模糊阈值进行监测,并引入可信度因子对Deb原实时诊断推理方法做了改进,解决了Deb方法可能因虚警而导致的诊断结果冲突的问题。模糊诊断Agent采用Mamdani算法,能给出部件故障的可能性。专家系统诊断Agent采用基于规则的产生式系统,同时采用加权不确定推理解决了规则的不确定性问题。研究了3种诊断Agent的协作方式,采用D-S证据理论对各Agent的诊断结果进行决策融合,给出故障元件的置信区间。通过某卫星仿真遥测数据验证,该集成诊断系统充分利用了各种诊断方法的优点,诊断精度高且速度快(一般诊断时间小于0.3秒,PIII800/256M计算机),适用于卫星地面站对卫星遥测数据进行自动实时在线监测与诊断推理。
