Quantum entanglement,since proposed by Einstein,Podolsky and Rosen(EPR)[1]and further explored by Schr?dinger[2]in1935,has always been the focus of quantum physics realm.The EPR paradox revealed the conflict between quantum theory and local realism.Almost 30 years later,in 1964,Bell first came up with the prototype of a family of inequalities,which was later called Bell inequality[3,4],to express certain limitation that every local clas-

The glass-forming regions of tellurium-gadolinium-tungsten ternary system prepared at 1000℃for 60 min were firstly determined.To improve density,the full replacement of lutetium for gadolinium to form Tb^(3+)-activated tellurium-lutetium-tungsten glasses with the composition of 64 TeO_(2)-20 WO_(3)-(16-y)Lu_(2)O_(3)-yTb_(2)O_(3)were designed for scintillation application.The concentration-dependent optical properties of Tb^(3+)-activated tellurium-lutetium-tungsten glasses were fully investigated by transmittance,excitation and emission spectra,together with the luminescence decay curves.The energy transfer mechanism was discussed according to Huang’s rule.The optimized 4 mol%Tb_(2)O_(3)activated tellurium-lutetium-tungsten glasses with the density of 6.49 g/cm^(3)and the lifetime of 0.551 ms are developing to be suitable for the potential detection of slow events in the future work.

AIM To further study the properties of bileliquid crystals,and probe into the relationshipbetween bile liquid crystals and gallbladderstone formation,and provide evidence for theprevention and treatment of cholecystolithiasis.METHODS The optic properties of bile liquidcrystals in human body were determined by themethod of crystal optics under polarizingmicroscope with plane polarized light andperpendicular polarized light.RESULTS Under a polarizing microscope withplane polarized light,bile liquid crystalsscattered in bile appeared round,oval orirregularly round.The color of bile liquidcrystals was a little lighter than that of the bilearound.When the stage was turned round,thecolor of bile liquid crystals or the darkness andlightness of the color did not change obviously.On the border between bile liquid crystals andthe bile around,brighter Becke-Line could beobserved.When the microscope tube is lifted,Becke-Line moved inward,and when lowered,Becke-Line moved outward.Under aperpendicular polarized light,bile liquid crystalsshowd some special interference patterns,called Malta cross.When the stage was turninground at an angle of 360°,the Malta cross showed four times of extinction.In the vibratingdirection of 45° angle of relative to upper andlower polarizing plate,gypsum test-board withoptical path difference of 530 nm was inserted,the first and the third quadrants of Malta crossappeared to be blue,and the second and thefourth quadrants appeared orange.When micatest-board with optical path difference of 147 nmwas inserted,the first and the third quadrants ofMalta cross appeared yellow,and the secondand the fourth quadrants appeared dark grey.CONCLUSION The bile liquid crystals weredistributed in bile in the form of global grains.Their polychroism and absorption were slight,but the edge and Becke-Line were very clear.Itsrefractive index was larger than that of the bile.These liquid crystals were uniaxial positivecrystals.The interference colors were the firstorder grey-white.The double refractive index ofthe liqui

The Noether current and its variation relation with respect to diffeomorphism invariance of gravitationaltheories have been derived from the horizontal variation and vertical-horizontal bi-variation of the Lagrangian, respec-tively. For Einstein's GR in the stationary, axisymmetric black holes, the mass formula in vacuum can be derived fromthis Noether current although it definitely vanishes. This indicates that the mass formula of black holes is a vanishingNoether charge in this case. The first law of black hole thermodynamics can also be derived from the variation relationof this vanishing Noether current.

When the cross section of J/ψproduction is considered as varying with the energy of the nucleon-nucleon interaction,the production of J/ψin pA and A A collisions has been studied by using FRITIOF Model.The calculation shows that the cross section of J/ψproduction“per nucleon-nucleon collision”decreases with the increasing mass number and centrality as a consequence of continuous energy loss of the projectile nucleons to the target nucleons in their successive binary nucleon-nucleon collisions.The model predictions have been compared with the experimental data of J/ψproduction.

The magnetic field and density behaviors of various thermodynamic quantities of strange quark matter under compact star conditions are investigated in the framework of the thermodynamically self-consistent quasiparticle model.For individual species,a larger number density n_(i) leads to a larger magnetic field strength threshold that aligns all particles parallel or antiparallel to the magnetic field.Accordingly,in contrast to the finite baryon density effect which reduces the spin polarization of magnetized strange quark matter,the magnetic field effect leads to an enhancement of it.We also compute the sound velocity as a function of the baryon density and find the sound velocity shows an obvious oscillation with increasing density.Except for the oscillation,the sound velocity grows with increasing density,similar to the zero-magnetic field case,and approaches the conformal limit V_(s)^(2)=1/3 at high densities from below.

The equivalence of the Ising model on a fractal lattice having two-and three-site couplings with the Ising model having only two-site interaction in a non-zero magnetic field on the same lattice is derived by a partial tracing which effectively decimates triplet interaction.It is shown that the system is in ordered phase and no phase transition exists at any finite temperature.Only trivial transition occurs at T=∞.In particular,we find that the pure triplet interaction Ising model is equivalent to one with pure nearest-neighbor pair interaction on the lattice,and the two systems have the same critical behavior.This is in contrast with that of triangular lattice and Sierpinski gasket fractal.
