人为干预强度及海象的短期和长期生存:阐述和量化研究对野生动物的影响

2003年

作者： Maxfield, clive

ISBN: (数字)9780080476025

ISBN: (纸本)9780750675437

From reviews of the first edition:"If you want to be reminded of the joy of electronics, take a look at clive (Max) Maxfield's book Bebop to the Boolean Boogie."--Computer Design "Lives up to its title as a useful and entertaining technical guide....well-suited for students, technical writers, technicians, and sales and marketing people."--Electronic Design"Writing a book like this one takes audacity! ... Maxfield writes lucidly on a variety of complex topics without 'writing down' to his audience." --EDN"A highly readable, well-illustrated guided tour through basic electronics." -Science Books & Films"Extremely readable and easy to understand, you'll wonder how people learned about this stuff before this book came along." --New Book Bulletin, Computer Literacy Bookshops* The difference between the analog and digital worlds.* What logic gates are and how to make them from transistors.

这一研究阐述了反复的人为干预对一个濒临灭绝的物种——南海象——存活率的影响,以及对野生动物研究的蕴涵。南海象幼崽在其出生后的前6周里不断的受到人为干预。这种人为研究可能已经改变了正在调查的一些参数,这样的可能性是我们这里所阐述的一个主要的和相关的研究领域。结果显示,那些反复受到干预,遭受入侵性研究方法的幼崽,从短期(24天的哺乳期)或长期(出生后的第一年或者更长)的生存率上来看没有受到明显的影响,受到干预一年后也很健康。我们没能发现受到人为干预强度最大和最小的海象的之间的存活率存在任何显著的差异,这支持了这一结论。

World Journal of Gastroenterology 2007年第27期13卷 3699-3704页

作者： clive H Wilder-Smith Joan robert-Yap Brain-Gut research Group Gastroenterology Group Practice Berne Switzerland Supported by the Brain-Gut Research Group Berne Switzerland

AIM： To investigate the role of endogenous pain modulatory mechanisms in the central sensitization implicated by the visceral hypersensitivity demonstrated in patients with irritable bowel syndrome （IBS）. Dysfunction of modulatory mechanisms would be expected to also result in changes of somatic sensory function. METHODS： Endogenous pain modulatory mechanisms were assessed using heterotopic stimulation and somatic and visceral sensory testing in IBS. Pain intensities （visual analogue scale, VAS 0-100） during suprathreshold rectal distension with a barostat, cold pressor stimulation of the foot and during both stimuli simultaneously （heterotopic stimulation） were recorded in 40 female patients with IBS and 20 female healthy controls. rESULTS： rectal hypersensitivity （defined by 95% Cl of controls） was seen in 21 （53%）, somatic hypersensitivity in 22 （55%） and both rectal and somatic hypersensitivity in 14 of these IBS patients. Heterotopic stimulation decreased rectal pain intensity by 6 （-11 to -1） in controls, but increased rectal pain by 2 （-3 to ＋6） in all IBS patients （P 〈 0.05） and by 8 （-2 to ＋19） in IBS patients with somatic and visceral hypersensitivity （P 〈 0.02）. CONCLUSION： A majority of IBS patients had abnormal endogenous pain modulation and somatic hypersensitivity as evidence of central sensitization.

clive Scott教授将翻译概念引入诗学研究,以其具有开拓性和实验性的研究成果在英、法文学及文学翻译领域引起相当关注。其翻译思想集中体现在Translating the Perception of Text—Literary Translation and Phenomenology和Literary Translation and the rediscovery of reading两部著作中。他将文学阅读视为一种语内翻译行为,认为翻译是译者向自身和其它读者展开自我的过程,译者需要寻求新的语言资源真实地反映其在阅读过程中所产生的心理、身体反映。Scott在翻译实践中积极尝试,创造出一套多模态符号用于翻译自己的阅读意识。本次访谈主要围绕Scott译论中引发关注的一些问题展开谈话,比如译文的文学性问题、翻译中的主体间性问题、阅读意识的符号转换问题等,也谈到他新出版的译论著作及其对AI科技时代文学翻译前景的展望。

railway Point System(rPS)is an important infrastructure in railway industry and its faults may have significant impacts on the safety and efficiency of train *** the fault diagnosis of rPS,most existing methods assume that sufficient samples of each failure mode are available,which may be unrealistic,especially for those modes of low occurrence frequency but with high *** address this issue,this work proposes a novel fault diagnosis method that only requires the power signals generated under normal rPS operations in the training ***,the failure modes of rPS are distinguished through constructing a reasoning diagram,whose nodes are either binary logic problems or those that can be decomposed into the problems of the binary ***,an unsupervised method for the signal segmentation and a fault detection method are combined to make decisions for each binary logic *** on the results of decisions,the diagnostic rules are established to identify the failure ***,the data collected from multiple real-world rPSs are used for validation and the results demonstrate that the proposed method outperforms the benchmark in identifying the faults of rPSs.
