Hypervelocity impact on rectangular plate-shaped Zr41Ti14Cu12.5Ni10Be22.5 bulk metallic glass(BMG)is performed by a two−stage light gas *** targets used in the experiment are BMG plates with a thickness of 5 *** projectile,spherical aluminum(3.1 mm in diameter),is accelerated up to various velocities;the light is detected with a *** emission lasts from 200µs up to 1500µs and the intensity increases from 44 to 900 W/(Sr⋅µm).The duration and intensity of a light emission seem to depend on the impact velocity and the extent of target destruction through the formation of impact craters or penetration.

Ownership structure is one of the most important and basic corporate governance characteristics. Thus, does the ownership structure of a firm have an effect on the type of audit opinion it receives from CPA？ This paper uses a sample including 1246 non-financial listed companies from China A-share market in 2003. Empirical results show： for listed firms, external auditor＇s propensity to qualify is lower with lower proportion of public shares, or with higher concentration of shares at a marginal significant level. However, the proportions of state-owned shares and institutional shares have no significant effects on audit opinions. A possible explanation is that the ownership structure influences risk awareness and negotiation power of audit firms, influences negotiation power of clients, and then ultimately influences auditors＇ reporting decision and audit opinions. The potential policy implication is： a more dispersed ownership structure and/or a higher proportion of public shares are preferable for higher audit reporting conservatism and audit quality in China.

Background： Increased serurn autoantibodies against interleukin-2 （anti-IL-2 autoantibodies） were reported in patients with systemic lupus crythematosus （SLE） and in patients receiving IL-2 therapy. This study aimed to explore the clinical relevance of serum anti-IL-2 autoantibodies and the interactions between low-dose IL-2 therapy and serum anti-IL-2 autoantibodies. Methods： Serum samples were collected from 152 SLE patients and 100 age- and gender-matched healthy controls （HCs）. Among them, 75 SLE patients were followed tip for 10 weeks, and all of them were treated with corticosteroids, antimalarials, and/or immunosuppressants. Forty-six out of the 75 SLE patients received low-dose IL-2 therapy additionally. Clinical and laboratory parameters were collected at baseline and week 10. Serum anti-lL-2 autoantibodies were determined by enzyme-linked immunosorbent assay. Results： Compared with HCs, median levels and positive rates of sernm anti-IL-2 autoantibodics were higher in SLE patients （32.58 [23.63, 45.23] arbitrary unit [AU] vs. 37.54 [27.88, 60.74] AU, P- 0.006, and 5.0% vs. 18.4%, P = 0.002, respectively）. Compared to those without the corresponding disorders, serum anti-IL-2 autoantibody was increased in patients with alopecia （49.79 [36.06, 64.95] AU vs. 35.06 [25.40, 58.46] AU, P = 0.033）, but it was decreased in those with lupus nephritis （31.71 [22.60, 43.25] AU vs. 44.15 [31.43, 68.52] AU, P= 0.001 ）. Moreover, serum anti-I L-2 autoantibody was positively correlated with serum IgA （r= 0.229, P = 0.005）, total lgG （r= 0.327, P 〈 0.001 ）, and total lgM （r=0.164, P = 0.050）. Treatment with exogenous IL-2 was not significantly associated with serum anti-IL-2 autoantibody. In addition, no significant difference was found in serum anti-lL-2 autoantibody between responders and nonresponders to low-dose I L-2 therapy. Conclusions： Serum anti-lL-2 autoantibody was increased and associated with disease severity in SLE. Exogenous low-dose IL-2 did not significant

《庄子》是苏轼博大人格和深厚思想的重要渊源。苏轼对生命自身本质的追寻深受庄子影响,他对生死祸福有超凡脱俗的透彻领悟。他推崇的理想人格任性逍遥,随缘放旷,摆脱名缰利锁,追求心灵自由。庄子思想指引苏轼在被贬生涯的恶劣的社会环境和生存环境中,超越苦难,寻找自我生命的新的价值,他的人生境界产生了质的飞跃。他摆脱了外在的功名利禄,祸福得失,追求心灵的丰富体验和精神的自由。同时他以新的审美眼光发现大自然,打破物我的界限,开启了山水诗词的新的境界。
