We develop and study the generalization of rational Schur algebras to the super *** to the classical case,this provides a new method for studying rational supermodules of the general linear supergroup GL(m|n).Furthermore,we establish a Schur-Weyl duality result for rational Schur superalgebras and conclude that under certain conditions these objects will be semisimple.

For a blockwise martingale difference sequence of random elements {Vn, n ≥ 1} taking values in a real separable martingale type p （1 ≤ p ≤ 2） Banach space, conditions are provided for strong laws of large numbers of the form limn→∞ Vi/gn = 0 almost surely to hold where the constants gn ↑∞. A result of Hall and Heyde [Martingale Limit Theory and Its Application, Academic Press, New York, 1980, p. 36] which was obtained for sequences of random variables is extended to a martingale type p （1〈 p ≤2） Banach space setting and to hold with a Marcinkiewicz-Zygmund type normalization. Illustrative examples and counterexamples are provided.

鲁伯特·默多克这个名字对你来说也许是陌生的。但是,《泰晤士报》、《太阳报》、《泰坦尼克号》,凤凰卫视、Channel V……这一个个耳熟能详的名字,都与这位72岁的老人有关。祖籍澳大利亚,具有英国教育背景,现定居美国,被不少人称作“中国女婿”的默多克是当今传媒业的风云人物。作为世界第五大传媒集团——新闻集团(News corp.)总裁、几十年来,他的影响力遍及世界。在英国,他与撒切尔政府关系紧密:布莱尔成功入主唐宁街十号,他功不可没;在美国,他周旋于达官显贵之中,受到高官普遍欢迎。但在中国.这位传媒大亨的梦想似乎并不那么顺利。然而正如中国新闻界著名教授喻国明教授指出:“新闻集团是世界五大传媒集团中最商业化的,默多克表人也是最能彻底剥离意识形态的。譬如他为了在美国发展生意.可以放弃自巴的澳大利亚国籍。不少政客和学者抨击他‘没有道德’、‘没有灵魂’,然而就是这种人安全度高,会令当局者放心,所以进来也就顺理成章。”从1993年默多克开始插足香港卫星电视,到2002年新闻集团旗下的星空卫视获准在广东落地,成为中国境内首家外资电视台.默多克用卫星覆盖全球的宏伟战略正一点一滴地慢慢实现。这是一个梦寐以求的愿望,这里是他第三任妻子邓文迪的故乡——中国。为了这一天,他耐心地等了16年!

Glycosides are essential structural motifs present in an array of important medicines,materials,and natural products[1].Nevertheless,the chemo-and stereoselective construction of the glycosidic linkage is a long-standing challenge because relatively minor variations in the glycosyl donor or acceptor’s structure can impact stereoselectivity,thus influencing the product's functional properties.

Although penetrating neck trauma （PNT） is uncommon, it is associated with the significant morbidity and mortality. The management of PNT has changed significantly over the past 50 years. A radiological assessment now is a vital part of the management with a traditional surgical exploration. A 22 years old male was assaulted by a screwdriver and sustained multiple penetrating neck injuries. A contrast CT scan revealed a focal pseudoaneurysm in the left common carotid artery bulb. There was no active bleeding or any other vascular injuries and the patient remained haemodynamically stable. In view of these findings, he was initially managed conservatively without an open surgical exploration. However, the patient was noted to have an acute drop in his hemoglobin count overnight post injury and the catheter directed angiography showed active bleeding from the pseudoaneurysm. Surgical exploration 40 hours following the initial injury revealed a penetrating injury through both arterial walls of the left carotid bulb which was repaired with a great saphenous vein patch. A percutaneous drain was inserted in the carotid tri- angle and a course of intravenous antibiotics for five days was commenced. The patient recovered well with no complications and remained asymptomatic at five months followup.
