The high-pressure structures of an underdoped cuprate superconductor Bi 2 Sr 2 CaCu 2 O 8+δ have been studied by synchrotron X-ray diffraction at pressures up to 36.5 GPa. We find that this superconductor retains its orthogonal structure with the space group Amaa in the pressure range studied. Upon compression, both the a and b axes first shrink monotonically up to 17.4 GPa from their ambient pressure values and keep these behaviors with positive compressibilities up to 36.5 GPa after experiencing expansion with negative compressibilities in the pressure regime between 17.4 and 23.7 GPa. However, the c axis decreases continuously with increasing pressure with a slow change at about 23.7 GPa. The results indicate an isostructural phase transition starting at 17.4 GPa and a structural collapse at around 23.7 GPa.

AIM: To investigate the effect of gadolinium chloride (GaCl3)and salvia miltiorrhiza compound (SMCo) on ischemia and reperfusion (I/R) injury in hepatocellular ***: Wistar rats were randomly to divided into control group, GaCl3 group, SMCo group and GaCl3 + SMCo group (n=15 each). GaCl3 (7 rmg@kg-1) was injected into tail vein on d 1 and d 2 in contrast group. SMCo ( 2 ml@kg-1) was injected into muscle on d 1 and d 2 in SMCo group. GaCl3+SMCo group received both GaCl3 (iv) and SMCo (im) injection. Control group received saline injection only. On d 3, all the rats were subjected to 2 h ischemia in the middle and left lobes of the liver, followed by reperfusion for 2 h, 6 h and 18 h respectively. The level of serum alanine aminotransferase (ALT) and malondialdehyde (MDA) in hepatocellular mitochondria was measured. Pathological changes in hepatic tissue and in hepatocellular mitochondria were determined with optical microscope and electronic microscope, ***: Remarkablly pathohistological and biochemical changes were detected after 6 h of I/R. Compared with control, the level of ALT was decreased in GaCl3, SMCo and GaCl3+SMCo treated groups (1 314.0±278.7 vs809.4±196.1,716.6±242.8 and 837.2±190.6 IU@L-1, respectively. P＜0.05).Similarly, the level of MDA was decreased in GaCl3, SMCo and GaCl3+SMCo treated groups (293.1±±51.1 vs 190.8±55.5,214.3±32.9 and 221.0±47.3 nmol@g-1, respectively, P＜0.05).Accordingly, in control group, swelling, degeneration, focal necrosis, infilt-ation of leucocyte were found in reperfused tissue under an optical microscope, and mitochondda swelling, rupture and even breakdown were seen under an electronic *** pathohistological and ultrastructural damages caused by I/R were greatly attenuated in GaCl3, SMCo and GaCl3+SMCo treated groups. However, there was no additive effect observed when GaCl3 and SMCo were used ***: Both GaCl3 and SMCo can alleviate the I/Rinjury in hepatocellular

The global spin alignment of vector mesons has been observed by the STAR collaboration at the Relativistic Heavy Ion Collider （RHIC） at Brookhaven National Laboratory （BNL）.It provides a unique opportunity to probe the correlation between the polarized quark and antiquark in the strongly coupled quark-gluon plasma （sQGP） produced in relativistic heavy ion collisions,opening a new window to explore the properties of s *** addition,spin alignments of vector mesons have also been observed in other high-energy particle collisions such as e+e-annihilations at high energies where hadron production is dominated by quark fragmentation *** results obtained are quite different from those obtained in heavy ion collisions where quark coalescence/combination mechanism dominates suggesting strong dependence on hadronization *** comprehensive studies in different hadronization processes are *** this article,we present a brief review of theoretical and experimental advances in the study of vector meson’s spin alignments in a variety of high-energy particle collisions,with emphasis on hadronization mechanisms.

Broadband and perfect terahertz absorber based on multilayer metamaterial using cross-ring patterned structures is proposed and investigated. The structure of the absorber is double absorption layers consisting of a chromium cross ring and eight isosceles right triangles. The unique structure of the double absorbing layers excites the electric dipole multimode resonance, giving rise to high absorption performance. Meanwhile, the influence of construal parameters on absorber behavior is also discussed. The numerical results show that the absorption achieves over 90% ranging from 2.45 THz to 6.25 THz and 99% absorption in the range of 3.7—5.3 THz. The realization of broadband and perfect absorber is described using the impedance matching principle. It is obviously found that the absorber is insensitive to the high angle of incidence for both transverse electric(TE) and transverse magnetic(TM) polarizations. Compared with the former reports, this absorber has remarkable improved absorption efficiency and smaller period. The terahertz absorber may be found applications in the fields of energy capture and thermal detection.
