Some results on the Induced Matching Partition Number of Product Graphs

The induced matching partition number of graph G is the minimum integer k such that there exists a k-partition (V1,V2,…Vk) of V(G) such that,for each i(1≤i≤k),G[Vi]is 1-regular.In this paper,we study the induced matching partition number of product graphs. We provide a lower bound and an upper bound for the induced matching partition number of product graphs, and exact results are given for some special product graphs.

基于偏向性技术进步视角的玉米产业节本增效潜力及途径研究[*]

基于诱致性技术创新理论,从偏向性技术进步的视角分析玉米产业节本增效途径。研究发现：2004-2018年玉米产业的生产率为降低趋势,主要是因为其技术进步率的降低导致生产率的损失。技术进步对玉米产出增长的贡献率达到40%以上,机械投入对产出增长的贡献率超过30%。玉米产业表现出较强的机械要素替代劳动力要素,但生物化学要素对土地要素的替代效应并没有很显著。玉米产业的技术进步路径表现为从提高土地生产率的生物化学型向提高劳动生产率的机械型技术进步模式转变,这与我国玉米产业技术发展趋势和地理特征有关。研究价值：为玉米产业实现技术进步和节本增效提供参考依据,对促进我国区域玉米技术进步、保证我国粮食安全具有重要理论和现实意义。

米非司酮配伍米索前列醇终止10－16周妊娠的探讨

目的探索米非司酮配伍米索前列醇(米索)终止10-16周妊娠有效剂量和给药途径.方法将371妊娠10-16周的健康妇女,随机分成3种不同的治疗组.A组120例,米非司酮25mg Bid×2天,第3天晨口服米索0.6mg,每4-5小时重复1次,最多3次;B组115例,米非司酮100mg Qd×2天,第3天晨口服米索0.6mg,4-5小时后阴道放置米索0.2mg,最多2次;C组136例,米非司酮50mg Bid×2天,第3天晨阴道放置米索0.6mg,每12小时重复1次,最多2次.结果3组24小时内流产成功率分别为87.5%、88.7%、94.1%,C组成功率明显高于A组和B组(p＜0.05).胃肠道副反应也明显降低(p＜0.05).结论口服米非司酮200mg合并首次阴道放置米索0.6mg是终止10-16周妊娠的良好方法.

A Likely Past: Abortion,Social Data,and a Collective Memory of Secrets in 1950s America

This essay analyzes the collective mnemonics embedded in the statistical discourse of Planned Parenthood's 1955 conference, Abortion in the United States. Conferees recalled a culture that was diseased, remembered both through social data on abortion pathology and epidemiology. The essay conceptualizes how to think of social data as a collective memory of secrets that is incumbent to biopower, particularly regarding statistical anonymity as a form of strategic amnesia. Although primarily a study of this conference, the essay notes the broader importance of collective memory and secrecy for the study of biopower.     

Quality-oriented technical change in Japanese wheat breeding

The article presents a productivity analysis of Japanese wheat breeding research. We first estimate a hedonic function to determine the marginal implicit values of Japanese wheat characteristics and find that protein contributes substantially to millers’ price offers to farmers. Induced innovation theory implies breeders thus should be responding to new protein-oriented price policies by developing high-protein wheat varieties. We test this hypothesis by estimating a distance function relating breeding resources – including what we call gene-recharge rates – to the yield and protein characteristics of discovered varieties. New varieties indeed have been protein-favoring and yield-disfavoring, suggesting government research programs have been market-oriented.     

心肌营养养-1与心肌肥大的生物学机制

心肌营养素-1(CT-1)是新近发现的促心肌肥大因子,除了有利于心脏发育并对心脏起一定的保护作用外,最主要的功能是通过作用于心肌细胞及促成纤维细胞生长和胶原合成来参与和调节心肌肥大。本文从其结构功能及引起心肌肥大的信号转导等方面对其导致的心肌肥大的生物学机制作以综述。
