1High sensitivity and high selectivity terahertz biomedical imaging显示文摘We demonstrate two distinct emerging terahertz (THz) biomedical imaging techniques.One is based on the use of a new single frequency THz quantum cascade laser and the other is based on broadband THz time domain spectrocopy.The first method is employed to derive a metastasis lung tissue imaging at 3.7 THz with clear contrast between cancerous and healthy areas.The second approach is used to study an osseous tissue under several imaging modalities and achieve full THz spectroscopic imaging based on the frequency domain or on a fixed THz propagation time-delay.Sufficient contrast is achieved which facilitated the identification of regions with different cellular types and density compositions.Seongsin M.Kim William Baughman David S.Wilbert Lee Butler Michael Bolus Soner Balci Patrick Kung 2011Chinese Optics Letters2011,9,11:4

3对英国住宅区域几种新型雨水收集利用系统的初步可持续性评估(英文)显示文摘由于缺乏对住宅雨水收集利用(RWH)系统类型的创新,在英国日常生活中的雨水收集利用还不是很广泛.介绍了一系列传统和新型的住宅RWH系统的初步研究结果,并对这些RWH系统进行了研究,研究方法包括:专利申请搜索、对行业专家的非正式访问、成本效益分析和简单的多准则分析法(MCA).然后基于社会优先、经济优先和环境优先的标准,研究了这些系统的可持续性.其中,对2种新型的RWH系统进行了更为详细的分析,并与传统的RWH系统进行对比.多准则分析法结果表明,创新型系统在更少的资金消耗下,可持续性绩效要高于传统系统.进一步的研究重点在于模拟这些被鉴定的系统来产生经验性数据库,并应用于WLC/LACs,寻找设备安装中可能出现的挑战和问题.Peter Melville-Shreeve Sarah Ward David Butler 2014Journal of Southeast University(English Edition)2014,30,2:3

15How much has the Sun influenced Northern Hemisphere temperature trends?An ongoing debate显示文摘In order to evaluate how much Total Solar Irradiance(TSI)has influenced Northern Hemisphere surface air temperature trends,it is important to have reliable estimates of both quantities.Sixteen different estimates of the changes in TSI since at least the 19th century were compiled from the literature.Half of these estimates are'low variability'and half are'high variability'.Meanwhile,five largely-independent methods for estimating Northern Hemisphere temperature trends were evaluated using:1)only rural weather stations;2)all available stations whether urban or rural(the standard approach);3)only sea surface temperatures;4)tree-ring widths as temperature proxies;5)glacier length records as temperature proxies.The standard estimates which use urban as well as rural stations were somewhat anomalous as they implied a much greater warming in recent decades than the other estimates,suggesting that urbanization bias might still be a problem in current global temperature datasets-despite the conclusions of some earlier studies.Nonetheless,all five estimates confirm that it is currently warmer than the late 19th century,i.e.,there has been some'global warming'since the 19th century.For each of the five estimates of Northern Hemisphere temperatures,the contribution from direct solar forcing for all sixteen estimates of TSI was evaluated using simple linear least-squares fitting.The role of human activity on recent warming was then calculated by fitting the residuals to the UN IPCC’s recommended'anthropogenic forcings'time series.For all five Northern Hemisphere temperature series,different TSI estimates suggest everything from no role for the Sun in recent decades(implying that recent global warming is mostly human-caused)to most of the recent global warming being due to changes in solar activity(that is,that recent global warming is mostly natural).It appears that previous studies(including the most recent IPCC reports)which had prematurely concluded the former,had done so because they failed to adequately consider all the relevant estimates of TSI and/or to satisfactorily address the uncertainties still associated with Northern Hemisphere temperature trend estimates.Therefore,several recommendations on how the scientific community can more satisfactorily resolve these issues are provided.Ronan Connolly Willie Soon Michael Connolly Sallie Baliunas Johan Berglund C.John Butler Rodolfo Gustavo Cionco Ana G.Elias Valery M.Fedorov Hermann Harde Gregory W.Henry Douglas V.Hoyt Ole Humlum David R.Legates Sebastian Liming Nicola Scafetta Jan-Erik Solheim Laszlo Szarka Harry van Loon Victor M.Velasco Herrera Richard C.Willson 晏宏 Weijia Zhang 2021Research in Astronomy and Astrophysics2021,21,6:1
