Nondestructive entangled-state analyzers could save the physical entanglement resource and boost the efficiency of quantum information processing (QIP). However, up to now, there is no much progress in the nondestructive analysis of Greenberger-Horne-Zeilinger (GHZ) states. In this paper, a nondestructive photonic polarization GHZ-state analyzer, based on the interaction between circularly polarized light and quantum-dot cavity systems, is proposed. We can distinguish the GHZ states deterministically in theory, and the states are not destroyed because no single-photon detectors are required. Our scheme can be extended to $$n$$ -photon GHZ states analysis directly and can be used to achieve QIP with less resource. [ABSTRACT FROM AUTHOR]

The objective of this study was to investigate the effects of ohmic (OH) and water bath (WB) cooking on shear parameters, protein degradation and ultrastructure changes of porcine longissimus dorsi muscle at the same endpoint temperatures (EPTs; range, 20-100 °C). The cooking loss and Warner-Bratzler shear force of the OH-cooked meat were significantly lower ( P < 0.05) while protein solubility, pH and endothermic transition temperature were higher than those obtained by WB cooking at the same EPTs (range, 20-80 °C). Sodium dodecyl sulphate polyacrylamide gel electrophoresis analysis showed that during OH cooking, the meat had slightly fainter protein bands than that of WB-cooked ones. Less obvious shrinkage of the sarcomere and loss in the structure of Z discs were detected especially in OH-cooked meat at EPTs (100 °C). Strong correlations among pH, cooking loss, Warner-Bratzler shear force, sarcoplasmic protein solubility, T, and T were observed in meat following OH cooking. [ABSTRACT FROM AUTHOR]

The juvenile Chinese mitten crabs Eriocheir sinensis (1.40 ± 0.43 g) were cultured in water of 5.34 ± 0.43 (hypoxia, treatment group) and 21.02 ± 0.06 kPa (high dissolved oxygen (DO), control group) DO for 24 h, respectively. The total hemocyte counts (THC), the hyaline hemocyte counts were measured at 0 and 24 h in the treatment group, and superoxide dismutase (SOD) activity, concentrations of lactic acid and hemocyanin (Hc) in hemolymph and the metabolism of hepatopancreas (concentrations of glucose, total cholesterol, uric acid, total protein, urea, triglyceride in hepatopancreas) were assayed at 0, 2, 8, and 24 h in both treatment and control groups. The hyaline hemocyte counts and THC decreased significantly by 66 and 49% after exposure to hypoxic water for 24 h, respectively. SOD activity, Hc and lactic acid content were significantly affected in treatment group, and there were significant differences between treatment and control groups. In the treatment group, the concentration of glucose, cholesterol and uric acid in hepatopancreas had a significant variation for 24 h. The concentration of total protein, urea and triglyceride between treatment and control groups was not significantly different after 0, 2, 8, 24 h. However, there were significant differences between treatment and control groups in terms of total protein, glucose, and uric acid concentration. Taken together, the effect of hypoxia is comprehensive in juvenile Chinese mitten crab Eriocheir sinensis. [ABSTRACT FROM AUTHOR]
