跨本体概念间相似度的计算方法——MD4模型
Determining Semantic Similarity among Concepts from Different Ontologies ——MD4 Model
董发花 黄宏斌 邓苏 刘震
MD3模型是一种系统的跨本体概念间相似度的计算方法,这种方法无需建立一个集成的共享本体。在MD3模型的基础上,充分利用本体对概念的描述信息,重点讨论了跨本体概念间非层次关系相似度的计算,把MD3模型扩展到MD4模型,使得概念间相似度的计算在理论上更全面、更精确。[著者文摘]
The MD3 model systematicly evaluates semantic similarity across different ontologies dispense with integrating different ontologies into a shared ontology. Based on the MD3 model, the not-hierarchical ralations evaluating of concepts from different ontologies is focused on, extended the MD3 model to MD4 model to make the semantic similarity of concepts from different ontologies more comprehensive and precise in theory.[著者文摘]
高热生物学与肿瘤治疗：对“Lance Armstrong效果”的假设
Hyperthermic Biology and Cancer Therapies A Hypothesis for the ＂Lance Armstrong Effect＂
Donald S. Coffey[1,3] Robea H. Getzenberg[1,3] Theodore L DeWeese[2,3] 彭楠（译）[4] 蒋彦勇（译）[4]
在肿瘤研究中，可能没有比懂得大多数睾丸癌患者能被非常有效地治疗的分子机理更为重要的了。例如，Lance Armstrong被诊断为晚期睾丸癌并发生转移，但是其治疗非常成功，以致随后他能赢得多项极限环法旅行比赛。尽管对此类晚期睾丸癌治疗成功目前已属平常，但是大多数其他类型晚期实体肿瘤仍无法达到这样的效果。如何解释睾丸癌治疗令人惊奇的疗效，能否于细胞和分子水平对其结果做出解释？了解Lance Armstrong疗效的基础可以为其他采用现行最佳系统治疗难以控制的晚期实体肿瘤的治愈提供治疗目标。[第一段]

银证系统中数据安全传输的综合防御措施
Integrated Security Recoery Method for Data Transmission in Stock and Bank System
周克江
2004年8月,在美国召开的国际密码学会议上,来自中国山东的王小云教授宣布成功破译了MD5、HAVAL-128、MD4和RIPEMD算法,并在任何初始值下用2^40次Hash运算给出了SHA-0的碰撞。这意味着目前广泛应用于电子商务、银行系统、证卷系统的安全认证算法——Hash函数分析领域堡垒的轰然倒塌。面对严峻而残酷的现实,依赖于Hash算法的银证系统数据安全传输问题,也就成为人们不得不及时解决的实际问题。该文给出了一种银证系统数据安全传输的综合防御措施。[著者文摘]
On the conference of the international cryptology association which was convened at the United States in August 2004, professor Wang who comes from Shandong of Chinese declared that they had successfully broken the algorithms of MD5, HAVAL-128, MD4 and f RIPEMD, and used the two of the fortieth power Hash operates under any initial value to give the collision of the SHA-0. This means that the algorithms of security authentication extensively applied currently in the electronic commerce, bank system, and stock system tumblingly breaks down, which is the field of Hash function analysis. Confronting with the rigorous and ruthlessness reality, people have to try to resolve this problem in time,which is the Hash functions based data transmission problems of the stock and bank system. Therefore, this paper provides a comprehensive defense measure of data transmission in the stock and bank system.[著者文摘]

利用静止气象卫星(GMS-5)高分辨数字资料(展宽数字资料，S-VISSR)和低分辨模拟云图(WEFAX)，结合沙尘暴在云图上的主要特征为，建立两种方法利用GMS资料显示沙尘暴的发生、发展和传输过程。并利用EP／TOMS卫星遥感资料结合地面气象观测记录，分析了2000年4月24日～26日和2001年3月21～22日影响我国的大部分地区的典型沙尘暴天气过程。揭示了沙尘天气对大气环境质量的影响。沙尘天气发生时北京出现5级重污染天气，大气可吸入颗粒物浓度从2001年3月19日的0．253mg／m^3猛增到3月22日的0．616mg／m^3，增加了将近2．5倍。从沙尘天气传输路径上若干城市2001年3月15日至25日大气可吸入颗粒物浓度的逐日变化，在长江中下游地区的几个城市大气颗粒物浓度的峰值出现在3月23日，这说明此次沙尘天气的影响范围很广。
铝对荞麦种子萌发的影响
The Effect of Aluminum on Germination of Buckwheat Seed
南益丽[1,2] 陈利[1,2] 刘鹏[2] 张文君[2]
以荞麦品种东阳荞麦、高荞三号、内蒙古产小白花、沈阳荞麦和依额苦荞为研究材料，设置5个不同铝处理浓度，研究铝对荞麦种子萌发的影响。结果表明，适当的铝处理能够促进荞麦种子萌发，增大荞麦的鲜重、发芽指数及活力指数，降低荞麦的质膜透性；5个荞麦品种对铝的敏感度以及耐铝性不同，其中东阳荞麦和高荞三号是为较耐铝的品种。[著者文摘]
The seeds of five different varieties of buckwheat Dongyangqiaomai （MD1）, Gac, qiao No. 3 （MD2）, Neimengguxiaobaihua （MD3）,Shengyangqiaomai （MD4） and Yierkuqiao （MDS）were soaked for 3 hours with different Al^3＋ concentration and then germinated for 8 days. the results showed that after seeds soaking in Al^3＋ solution of proper concentration, the germination rate, fresh weight of single plant, germination index（GI）, vigor index （VI）were all increased, while electric conductivity was decreased. Soaking seeds trader 2 （300 mg/L Al^3＋ was best benefit to germination and stress resistance of MD1 and MIY2, while 100 mg/L or 500 mg/L Al^3＋ was best for MD3 ,MD4 and MD5. ^he results also showed that the stress resistance and the sensitivity of five buckwheat varieties to aluminum were different.[著者文摘]
