简介：与谈论气候的世界，变化，美国(美国)，中国和印度宣布了他们的碳排放减小目标。这三个国家完成他们的目标，重要问题产生例如将是完成那些目标的年度排放减小努力的，它将花费多少并且什么将是经济效果。这份报纸把中国和印度的碳紧张减小目标放进和美国的绝对排放减小目标一样的非线性的模型到最佳的排放控制策略和联系总数为在一年2020完成那些目标花费了的份量上学习，并且估计并且比较三个国家的最小化的全部的费用到达他们的目标。我们总数花费了让美国完成它的排放减小目标的结果表演以绝对数量比中国和印度的那些大。以到GDP的全部的费用的比例，然而，中国和印度比率比美国的显著地大，显示为象中国和印度那样的发展中的国家，排放减小目标的成就需要相对更大的努力。

简介：摘要随着我国社会的发展进步，各行各业也随之得到了发展，医院也进行了大规模的改革，绩效工资改革是许多医院采用的财务管理方法，在改革过程中也受到了很多阻碍，因此，很多医院的绩效工资制度存在着一些问题等待改进。文章通过几年来我院绩效工资发放实践，进一步调动了医务人员的工作积极性，对农村卫生事业发展起到了积极的推动作用。

简介：攻克癌症一直是科学家努力的方向。然而,癌细胞以其复杂多样的代谢方式和生态微环境给癌症的治疗带来极大困难。常规的癌症化疗,在高毒性的药物作用于全身造成强烈毒副作用的同时,病灶的药效却随之大幅降低。事实上,很多患者最后死于药物毒副作用或耐药性及由此引起的转移。因此,开发无毒、安全和高效的癌症治疗体系尤为重要。
