Abdallah Daar, of the Canada-based McLaughlin-Rotman Centre for Global Health and lead author of the paper, said the consensus forms a'road map'for policymakers and researchers.

该论文的第一作者、加拿大McLaughlin-Rotman全球卫生中心的Abdallah Daar说，该共识形成了一个供决策者和研究者使用的“路线图”。

Daar was unable to confirm how much money has been put into the alliance but says it means that chronic diseases will have a larger share of research funding.

Daar无法证实有多少资金已经投入了该联盟，但是他说这意味着慢性病将在科研资助中拥有更大的份额。

Daar's suggestions were based on a survey of emigrated scientists that he and his colleagues led in Canada.

多伦多大学达尔的建议是基于一项他和同事在加拿大进行的对移居海外的科学家进行的调查。

Sometimes, DaaS providers may bill for database utilization by including the elapsed CPU time since one request used more CPU time than what is typical.

有时候，由于一个请求会比通常情况使用更多的CPU时间，DaaS供应商会将CPU运行时间包含到数据库使用量计费中。

A few years later, old Jehan DAAS lost the use of his limbs on account of rheumatism.

几年后，老耶汉？达斯因患风湿症而四肢瘫痪。

Though Jehan Daas had very little food to eat every day, he brought up the child with pleasure.

虽然耶汉？达斯每天几乎三餐不继，他仍满心欢喜地把小孩养大。

This groundwork helps the implementation of software license agreements in DaaS models.

这样的基础工作可以帮助在DaaS模型中实现许可协议。

Therefore, DABM built in this paper can efficiently put activity cost calculation and activity cost management together to serve 3PLs cost management better.

因此，本文建立的部门作业成本核算和管理模型能够更有效地将作业成本核算与作业成本管理结合起来，更好地为企业管理服务。

The differences in the means of SBP, DBP and MAP between CBP and dABP were 13.2,10.0 and 11.6 mmHg respectively in the hypertension group, and they were significantly higher than those in the normal BP group.

CBP与dABP间的SBP、DBP、MAP均值的差值分别为13.2,10.0和11.6mmHg，并均明显高于血压正常组的两者差值（P<0.01）。

In view of the low speed of convergence of the back-propagation algorithm ( BP) and the local minimum problem existing in the BP algorithm, a disturbing accelerating back-propagation algorithm ( DABP) is established.

针对BP算法收敛速度慢且存在局部极小值的问题，提出了基于扰动的加速神经网络DABP模型；
