Communications in Theoretical Physics 2007年第2期47卷 257-260页

作者： wang Xin-Wen wang zhi-yong XIA Li-Xin Department of Physics Hunan University of Science and Engineering Yongzhou 425100 China Department of Physics Hengyang Normal University Hengyang 421008 China

We present a theoretical scheme for perfect teleportation of an unknown multipartite two-level state by a single EPR （Einstein-Podolsky-Rosen） pair, and then generalize it to multilevel, i.e., an N-quNit state can be teleported by a single quNit entangled pair, with additional local unitary operations. The feature of the scheme is that teleporting a multipartite state with a reduced amount of entanglement costs less classical bits.

路由协议如开放的最短路径优先协议OSPFV2的安全运行对网络的连通及信息安全传输至关重要。传统OSPFV2协议在设计上缺少抵御源路由伪造或路由信息篡改的能力,致使组网易遭遇攻击,而现有的安全策略多为外挂式,易引发新的安全问题或安全效能低,为此,提出基于标识密码的内生安全OSPFV2协议,将标识密码内嵌于路由交换流程内,使网络具备高效的、内生式的抵御路由在传输过程中的篡改和伪造攻击能力。另一方面,考虑大范围部署安全OSPFV2协议存在多种限制因素,利用不透明链路状态通告,设计支持增量部署的运行机制。仿真实验表明,设计的内生安全OSPFV2协议在不损耗过多收敛时延的同时,具备抵御源路由伪造、数据篡改的安全能力。

目的探讨多巴胺受体D3~D5在不同物种小肠的分布和定位。方法应用免疫组织化学和免疫印迹法,分别检测D3~D5在小鼠、大鼠和恒河猴小肠的分布及表达水平,通过免疫荧光双标技术观察小肠固有层(LP)免疫球蛋白A阳性浆细胞(IgA^(+)PC)中D3~D5的表达。结果D3和D5在小鼠、大鼠和恒河猴小肠的上皮层、LP、黏膜下神经丛(SMP)和肌间神经丛(MP)内广泛分布;D4在小鼠和恒河猴小肠的分布与D3和D5一致,但在大鼠小肠仅分布于上皮层和LP。小鼠和大鼠LP内的IgA^(+)PC均表达D3和D5,不表达D4。结论D3和D5在小鼠、大鼠和恒河猴小肠具有相似的分布和定位模式,D4则存在物种差异。多巴胺可能参与调节IgA^(+)PC的功能。

In terms of the volume-integrated Poynting vector, we present a quantum field-theory investigation of the zitterbewegung （ZB） of photons, and show that this ZB occurs only in the presence of virtual longitudinal and scalar photons. To present a heuristic explanation for such a ZB, by assuming that the space time is sufficiently close to the flat Minkowski space, we show that the gravitational interaction can result in the ZB of photons.

This letter used the molecular imprinting technology to build up the microenvironment around co-monomer bemin to mimic the cytochrome P450 catalyzing the epoxidation of styrene. The results showed that the conversion rates of products were obviously enhanced by molecularly imprinted polymers, compared to free heroin solution, using three kinds of oxidants. The used axial ligand in polymers synthesis also improved the total conversion rates.

OBJECTIVE To reveal the biological effects and effective dosage in radiotherapy model which applies high single-dose irradiation by animal experiment. METHODS We inoculated subcutaneouly human pancreatic carcinoma cell line （MIA PaCa-2） in the lateral of the right lower extremity of the athymic mouse to grow transplantation tumor. While the median diameter of transplantation tumor reached 10 mm approximately, the animals were randomly divided into 7 groups （6 animals per group） and irradiation by different dose in one fixed with consciousness for fraction （0, 2, 5, 10, 17, 25, 35 Gy）. All were kept on to be bred for observation of the change in gross tumor volume, calculation of delayed growth time and delayed growth curve. RESULTS With increased dose per fraction, cutaneous reaction on the neoplasma surface of the animal, which was mainly moist yellow effusion was more and more severe. When dosage is less than 10 Gy, all animals showed similar effects, that＇s the delayed tumor growth was not obvious. Tumors receiving more than 10 Gy in one fraction showed very good biological effect and the delayed tumor growth was obviously related to dosage. The difference in delayed tumor growth between the 2 groups was statistically significant. The delayed tumor growth time in 10, 17, 25 Gy group was respectively 3 weeks, 6 weeks and more. CONCLUSION The biological effect of the model which applies high single-dose irradiation （more than 10 Gy in one fraction） was very good. The effect of delayed tumor growth was obviously related to the dosage after transplantation tumor was radiated. Because of its higher dose per fraction and biological effects, the model of high single-dose irradiation can get better clinical effects.
