Luhrmann's soft-filtering lens — a man being trampled to death by rampaging cattle or a city being annihilated by bombing Japanese warplanes — the calamities of history are merely colorful grist for his main interest, the romance between a wilted English rose, Lady Sarah Ashley, and an itinerant Australian cattleman, the Drover. The lady and the tramp meet soon after she lands in Australia to track down her cattleman husband, whose early murder sets all the narrative pieces in place. Initially intent on selling her property, including 1,500 head of cattle, Sarah soon transforms into a frontierswoman, seduced by Nullah's smile and the majestic valleys and peaks of both the land and of the Drover's musculature.

If two parties want to sign a contract C over a communication network, they must "simultaneously" exchange their commitments to C Since simultaneous exchange is usually impossible in practice, protocols are needed to approximate simultaneity by exchange partial commitments in a piece by piece manner The party of secondly sending commitments may have a slight advantage; a "fair" protocol must keep this advantage within acceptable limits The protocol for signing a contract is improved based on the research result of secure multiparty computation In this protocol, the parties obliviously transfer the signed bit and the committed bit; the other parties can prove the validity of this bit based on the confirming sub protocol, but he cant gain more information about the whole signature by accumulating the signed bit or the committed bit After the parties exchange the whole signed information, they declare the commitment about the signature respectively, and gain the whole signature of the other party At this moment, the party doesnt care about the advance quit of the other party, because he has gained the whole signed information Finally, it is proved that this protocol is quit fairness

在网络环境中解决合同签订问题需要保证信息交换的同时性，以前提出的协议都会给第 2个发送者部分计算特权，利用不经意传输协议则可以解决这个问题在协议执行过程中，参与者将合同的签名位以及他对签名位的承诺不经意传输给对方，对方可以利用验证子协议证明该位的有效性，但是他却不能通过位交换次数的增加获取更多的完整签名的信息；在完成签名位的交换之后，参与者分别宣布承诺，并得到对方对合同的完整签名；在宣布承诺时，协议参与者已经获得全部的签名内容，要么是签名位，要么是对方对该位的承诺，因此参与者并不需要担心对方提前终止协议在文章的最后利用多方安全计算的结论证明了该协议满足终止公平性1 引言两个参与者A和B想要通过网络协商签订合同C 为了保证公平性，参与者必须同时交换自己对合同的签名，然而在实际的网络环境中，想要完全同时地交换对合同的签名是不可能的，他们必须将签名分成若干块依次地执行，以保证大致的同时性但是这种方法依然存在着问题

What bothered Torre most was Rodriguez's seeming obliviousness to how badly he was playing. In June, for instance, hitting coach Don Mattingly ordered Rodriguez into the cage and sternly lectured him on the flaws in his swing, which Mattingly thought A-Rod had been unwilling to address."An intervention," Mattingly called it."He got to a pretty good point with , but it lasted only a few days and he went right back to where he was."

最为困扰著Torre的是， A-Rod似乎没有意识到自己的表现有多麼糟糕，举例来说，今年六月的某一天，打击教练Don Mattingly要求A-Rod进入打击练习区，然后严厉地指出A-Rod挥棒动作中的瑕疵，当时他认为A-Rod本人并没意识到这些问题，而自己有义务帮他做些调整，"当时他的挥棒动作的确有所改善，不过这样的认知和调整只持续了几天，他又回到了老样子"

D modal tuning: D-A-d-g-a-d' and D-A-d-a-d'-d' Popularised by Davey Graham, who had been inspired by Arabic oud tuning while living in Morocco. D modal tuning D-A-d-g-a-d' is now encountered in Celtic music and contemporary music.

形式调弦D D-A-d-g-a-d' and D-A-d-a-d'-d'由Davey Graham推广起来的调弦，这个调弦是他在摩洛哥时从阿拉伯音乐调弦中得到的灵感，形式和弦D D-A-d-g-a-d'与赛而特音乐及现代音乐中常常可以遇到。

Results ①The mean value of wound healing time of group A, B and C was 10.4±1.0、17.8±1.6、11.4±1.3 days respectively.②The granulation of group A and C filled wound area at 4th～5th day after injury; The granulation of group B began to grow into the wound area under necrotic cartilage at 10th day after injury ③The mean value of elevating height of group A, B and C was 1.20±0.56、1.68±0.73、1.15±0.50 mm respectively.

结果：①A、B、C三组平均创面愈合时间分别为(10.4±1.0)天、(17.8±1.6)天、(11.4±1.3)天，三组之间统计学比较有显著差异；②A、C两组伤后4～5天肉芽组织充满创面，B组在伤后第10天，肉芽组织开始在坏死软骨下向中心生长；③A、B、C三组瘢痕隆起高度为(1.20±0.56)mm、(1.68±0.73)mm、(1.15±0.50)mm，B组与A、C组统计学比较有显著差异。

Finally, the relationship between the performance of doped a-Si: H and process conditions is discussed, which includes the deposition of n〓-a-Si: H and p〓-a-Si: H, the relationship between dark conductivity, photoconductivity of boron light-doped a-Si: H and process conditions, and the relationship between the stability of LCLV and S-W effect of a-Si: H.

最后讨论了掺杂a-Si：H的性能与工艺条件的关系，包括重掺杂n〓、p〓非晶硅的制备，硼轻掺杂a-Si：H的暗态电导率与工艺条件的关系，硼轻掺杂a-Si：H的光电导与工艺条件的关系，以及液晶光阀的稳定性与a-Si：H的S-W效应。

The three groups were loaded and analyzed under the same loading according to the mean value of the bite force of incisors. RESULTS:(1)The maximum stress of dentin in group A was twice higher than that in group B. The maximum primary stress, minimum primary stress and maximum shear stress of group A were respectively 236.35, 228.83 and 218.05 percent of those in group B. The difference of maximum stress values of group B and group C was neglectable.(2) The maximum stress distribution of dentin in group A and group B was quite different (the stress was concentrated in labial and lingual side of the cervical dentin in group A, otherwise in group B it was concentrated in the area around the alveolar and the labial and lingual side of the dentin which was opposite to the tip of the cast metal post and core). The maximum stress distribution of dentin in group A and group B was almost the same.

结果：(1)从牙本质的应力大小来看，A组中牙本质最大应力值比B组中牙本质最大应力值增大了1倍以上（最大主应力、最小主应力和最大剪切应力A组分别是B组的236.35%、228.83%和218.05%），而B组与C组的牙本质最大应力值相差极小；(2)从牙本质的应力分布位置来看，A组与B组的牙本质最大应力分布位置相差甚远（A组主要集中在牙颈部唇舌侧肩台部的牙本质上，B组主要集中于牙槽嵴顶附近及铸造桩核尾端相对应的唇舌侧的牙本质上），而B组与C组的牙本质最大应力分布几乎在同一位置。

While early studies focused on the potential roles in health and disease of provitamin A carotenoids, such as b-carotene, research over the past decade has provided a framework for our understanding of the functions of non-provitamin A carotenoids such as lycopene, especially in regards to its association with a reduced risk of a number of chronic diseases, including cancer.

人们早期的研究多关注于如β胡萝卜素等维生素A前体类胡萝卜素对于健康和疾病的潜在作用，而近几十年的研究为对于如番茄红素等非维生素A前体类胡萝卜素的功能认知提供了参考，特别是关于它与降低包括癌症在内等慢性病的患病风险的联系。
