1功率因数校正的数字控制技术应用研究显示文摘以单管Boost型PFC电路作为研究对象,分别针对电流断续、电流临界连续和电流连续3种工作模态,详细讨论了数字控制PFC的实现方法和设计过程,并分别给出了样机实验结果;此外,结合M C 56F 8013的外设资源特点,给出了基于DSP的PFC详细的系统接口设计,包括PWM控制策略和同步控制AD采样环节。对PFC的数字控制方案进行了系统研究,提供了不同工作模式下的完整数字控制解决方案,为功率因数的数字控制技术应用提供了较好的参考作用。陈新 Charlie Wu W Hutchings 2007南京航空航天大学学报2007,39,2:8
2俄罗斯Samara州医务人员结核病发病率上升:登记数据分析显示文摘地点:俄罗斯Samara州。目标:比较俄罗斯某地结核病机构医务人员、综合医疗机构医务人员和普通人群的结核病发病率。方法:分析1994-2002年的9年期间结核病机构医务人员、综合医疗机构医务人员和普通人群的结核病登记率。结果:从1994到2002年,Samara州结核病机构医务人员的结核病发病率比普通人群的发病率高10倍,达到741.6/10万人年。结核病机构住院部医务人员的发病率最高,其发病率与综合医院医务人员发病率的率比为17.7(95%可信区间为11.6-27.0)。结论:俄罗斯结核病机构医务人员的结核病发病率显著上升,提示院内感染的危险很大。控制俄罗斯院内结核病传播是一个需要迫切关注的问题,尤其是俄罗斯目前正面临着人类免疫缺陷病毒的流行。B.

3“梦想”普通话标准化评估在听障儿童语言测试中的应用显示文摘目的本文讨论了用口语交流的听障儿童语言发展效果评估的最新实证。方法研究强调,语言评估须足够具体,才能捕捉到细微的词汇及语法缺陷。'普通话听力理解和表达能力标准化评估'(Diagnostic Receptive and Expressive Assessment of Mandarin,DREAM,译为'梦想')抓住儿童普通话习得的核心特征,是基于中国大陆地区的普通话儿童来建立常模的综合性的语言测试,可以测量中国大陆儿童在各个年龄阶段的语言技能。声音和图片通过平板电脑呈现,答案以触屏的方式进行记录,减少了人为差异,使操作更加标准化。结果本文报告了DREAM的题目设计、信度和效度研究等内容。试验研究显示,该测试可提供听障儿童语言发展的详细信息。测试可提供诊断儿童具体语言发育缺陷的报告,用来指导康复计划的制定,使更加个性化的康复干预成为可能。结论 DREAM是转化科学的成功范例——把科研结果从语言习得的循证研究转移到临床评估和干预康复的应用领域。以循证医学为基础的综合性普通话语言测试将推动中国听障儿童干预和康复的效果评估研究。刘雪曼 de Villiers,Jill 宁春岩 Rolfhus,Eric Hutchings,Teresa Lee,Wendy 江帆 章依文 2015中华耳科学杂志2015,13,4:7
4New language outcome measures for Mandarin speaking children with hearing loss显示文摘Objective:The paper discusses recent evidence on the assessment of language outcomes in children with hearing loss acquiring oral language.Methods:Research emphasizes that language tests must be specific enough to capture subtle deficits in vocabulary and grammar learning at different developmental ages.The Diagnostic Receptive and Expressive Assessment of Mandarin(DREAM) was carefully designed to be a comprehensive standardized Mandarin assessment normed in China's Mainland.Objective:The paper discusses recent evidence on the assessment of language outcomes in children with hearing loss acquiring oral language.Methods:Research emphasizes that language tests must be specific enough to capture subtle deficits in vocabulary and grammar learning at different developmental ages.The Diagnostic Receptive and Expressive Assessment of Mandarin(DREAM)was carefully designed to be a comprehensive standardized Mandarin assessment normed in China's Mainland.Results:This paper summarizes the evidence-based item design process and validity and reliability results of DREAM.A pilot study reported here shows that DREAM provided detailed information about hearing impaired children's language abilities and can be used to aid intervention planning to maximize progress.Conclusion:DREAM represents an example of translational science,transferring methods from empirical studies of language acquisition in research environments into applied domains such as assessment and intervention.Research on outcomes in China will advance significantly with the availability of evidence-based comprehensive language tests that measure a sufficient age range of skills,are normed on Mandarin speaking children in China's Mainland,and are designed to capture features central to Mandarin language acquisition.Xueman Liu Jill de Villiers Wendy Lee Chunyan Ning Eric Rolfhus Teresa Hutchings Fan Jiang Yiwen Zhang 2016Journal of Otology2016,11,1:4
5经济衰退对高校图书馆和IT服务的影响评估显示文摘Ipsos MORI代表JISC,SCONUL和UCISA做过一项研究,表明尽管高校图书馆和信息技术(IT)服务业可能还没有充分体会到经济衰退所产生的“挤压感”,但鉴于2010或2011年可能会出现各项经费的削减,Charles Hutchings(著) 马翠翠(编译) 2010图书情报工作动态2010,,1:3
6Laetmonice iocasica sp.nov.,a new polychaete species(Annelida:Aphroditidae)from seamounts in the tropical Western Pacific,with remarks on L.producta Grube,1877显示文摘Laetmonice Kinberg,1856 is a remarkable genus characterized by having harpoon notochaetae in the polychaete family Aphroditidae.We describe a new species of Laetmonice,Laetmonice iocasica sp.nov.,found from seamounts on the Caroline Ridge in the tropical Western Pacific.The new species is readily distinguished from congeners,particularly those distributed in the Indo-Pacific Ocean by possessing45 segments with 18 pairs of elytra,and the tuberculated harpoon notochaetae in the elytrigerous segments,which are replaced by tuberculated notochaetae without recurved fangs on segments 4 and 5.Laetmonice iocasica sp.nov.is closely related to L.producta Grube,1877,but differs in both morphology and the genetic distance of the mitochondrial cytochrome oxidase subunit I(COI)sequences.Laetmonice producta Grube,1877 contained five varieties reported in various marine areas,which have been raised to species level.However,the records of L.producta from the Sagami B ay and Suruga B ay in Japan and in the south-eastern Australia remain obscure and probably represent a different species.The data indicate that L.producta,which was originally described from Kerguelen Islands in the Southern Ocean and later commonly found on the Antarctic shelf,is probably distributed only at high latitudes of the Southern Hemisphere.Xuwen WU Pat HUTCHINGS Anna MURRAY Kuidong XU 2021Journal of Oceanology and Limnology2021,39,5:2
