1Adaptive optical microscopy: the ongoing quest for a perfect image显示文摘Adaptive optics is becoming a valuable tool for high resolution microscopy,providing correction for aberrations introduced by the refractive index structure of specimens.This is proving particularly promising for applications that require images from deep within biological tissue specimens.We review recent developments in adaptive microscopy,including methods and applications.A range of advances in different microscope modalities is covered and prospects for the future are discussed.Martin J Booth 2014Light(Science & Applications)2014,3,1:19
2狗尾草根系固土拉力的原位测定显示文摘应用锚杆拉力计和自行设计的剪切箱对狗尾草根系的固土能力在深度为10cm和20cm进行了原位测定,结果表明:在10cm深度,当施加的载荷增大到4.9kN时,狗尾草样方位移为53.3mm,而裸地样方承受的最大载荷为4.4kN,在此载荷下位移达到了55.0mm。在20cm深度,当施加的载荷增大到5.3kN时,狗尾草样方位移为53.7mm,而裸地样方承受的最大载荷为4.0kN。该测定方法可以在水土保持上作为评价不同作物(植物)固土能力的有效手段。毛妍婷 郑毅 李永梅 M A Fullen C A Booth 2009土壤通报2009,40,3:15
3非洲裔美国人体力活动与高血压发生的相关性显示文摘非洲裔美国人在美国各种族(民族)中高血压患病率(男性为40.8%,女性为41.5%)最高。有证据表明,与美国其他种族(民族)相比,非洲裔美国人高血压与因心肌梗死、脑卒中和终末期肾脏疾病引起的过早功能丧失和死亡呈不成比例地升高相关。需要确定控制非洲裔美国人危险因素的措施,以减轻其发生高血压的风险。在许多其他人群中已证实,体力活动对预防高血压有保护作用。因此,高血压指南推荐采用体力活动作为预防性生活行为方式。Diaz KM Booth JN 3rd Seals SR Abdalla M Dubbert PM Sims M Ladapo JA Redmond N Muntner P Shimbo D 2017中华高血压杂志2017,25,2:10
4Multifractal Simulation of GeochemicalMap Patterns显示文摘Using a simple multifractal model based on the model De Wijs, various geochemical map patterns for element concentration values are being simulated. Each pattern is self-similar on the average in that a similar pattern can be derived by application of the multiplicative cascade model used to any small subarea on the pattern. In other experiments, the original, self-similar pattern is distorted by superimposing a 2-dimensional trend pattern and by mixing it with a constant concentration value model. It is investigated how such distortions change the multifractal spectrum estimated by means of the 3-step method of moments. Discrete and continuous frequency distribution models are derived for patterns that satisfy the model of De Wijs. These simulated patterns satisfy a discrete frequency distribution model that as upper bound has a continuous frequency distribution to which it approaches in form when the subdivisions of the multiplicative cascade model are repeated indefinitely. This limiting distribution is lognormal in the center and has Pareto tails. Potentially, this approach has important implications in mineral and oil resource evaluation.Agterberg Frederik P Geological Survey of Canada, 601 Booth Street, Ottawa, K1A 0E8, Canada 2001Journal of China University of Geosciences2001,12,1:10
5长期使用抗生素引起大肠埃希菌产生耐药性与基因突变的鉴定显示文摘产超广谱β内酰胺酶(ESBLs)菌株多重耐药给临床治疗造成了极大的困难,在多种耐药机制中,产生β内酰胺酶(BLA)是细菌对BLA类抗生素耐药最主要的机制[1].为此,我们对患多发性肝脓肿的一例患者进行了追踪分析,在其长期使用抗生素治疗期间,从肝脓肿穿刺液和血培养液中分离出有代表性的7株大肠埃希菌,对它们形成耐药的环境、发生突变的途径和产生突变的类型进行了探讨研究.戎建荣 李连青 刘小玉 王淑峰 周向红 朱庆义 Ian Booth 2004中华检验医学杂志2004,27,8:6

7Experimental Study of the Adsorption-Induced Coal Matrix Swelling and Its Impact on ECBM显示文摘Carbon dioxide(CO_2) enhanced coalbed methane(ECBM) is an effective method to improve methane(CH_4) production and this technology has already been used to increase gas production in several field trials worldwide. One major problem is the injection drop in the later period due to permeability decrease caused by coal matrix swelling induced by CO_2 injection. In order to quantify the swelling effect, in this work, coal samples were collected from the Bulli coal seam, Sydney Basin and adsorption tests with simultaneous matrix swelling measurement were conducted. The adsorption and swelling characteristics were analyzed by measuring the adsorption mass simultaneously with the strain measurement. Then experiments were conducted to replicate the ECBM process using the indirect gravity method to obtain the swelling strain change with CO_2 injection. The results show that the coal adsorption capacity in CO_2 is almost two times greater than that in CH_4, and nitrogen adsorption is the least among these gases. A Langmuir-like model can be used to describe the strain with the gas pressure and the swelling strain induced by gas adsorption has a linear relationship with gas adsorption quantity. Moreover, swelling strain increase was observed when CO_2 was injected into the sample cell and the swelling strain was almost the sum of the strains induced by different gases at corresponding partial gas pressure.Jia Lin Ting Ren Gongda Wang Patrick Booth Jan Nemcik 2017Journal of Earth Science2017,28,5:4
8有无透明带牛卵母细胞孤雌发育研究显示文摘研究探讨了不同浓度的钙离子载体 (A2 3187)结合 6 二甲氨基嘌呤 (DMAP)或丁内酯I (BL -I)激活处理对有或无透明带牛卵母细胞孤雌发育的影响。结果表明 :使用A2 3187浓度从 0 .6 2 5~ 10 .0 0 0 μmol/L配合 2 .0mmol/LDMAP孤雌激活牛具透明带卵均能获得良好的卵裂及早期胚胎发育效果 ;对于去透明带卵来说 ,使用 0 .6 2 5 μmol/L浓度的A2 3187激活效果最佳。BL I的激活效果则明显差于DMAP ;当采用 0 .3%PVA取代激活液中的 5 %血清时 ,BL I的激活效率显著提高。谭世俭 P J Booth H Callesen 2004黑龙江畜牧兽医2004,,2:4
9Spatial context in the calculation of gas emissions for underground coal mines显示文摘The prediction of gas emissions arising from underground coal mining has been the subject of extensive research for several decades, however calculation techniques remain empirically based and are hence limited to the origin of calculation in both application and resolution. Quantification and management of risk associated with sudden gas release during mining(outbursts) and accumulation of noxious or combustible gases within the mining environment is reliant on such predictions, and unexplained variation correctly requires conservative management practices in response to risk. Over 2500 gas core samples from two southern Sydney basin mines producing metallurgical coal from the Bulli seam have been analysed in various geospatial context including relationships to hydrological features and geological structures. The results suggest variability and limitations associated with the present traditional approaches to gas emission prediction and design of gas management practices may be addressed using predictions derived from improved spatial datasets, and analysis techniques incorporating fundamental physical and energy related principles.Patrick Booth Heidi Brown Jan Nemcik Ren Ting 2017International Journal of Mining Science and Technology2017,27,5:4

12Ultra-broadband all-OPCPA petawatt facility fully based on LBO显示文摘A petawatt facility fully based on noncollinear optical parametric chirped pulse amplification(NOPCPA)technology,Vulcan OPPEL(Vulcan OPCPA PEtawatt Laser),is presented.This system will be coupled with the existing hybridCPA/OPCPA VULCAN laser system(500 J,500 fs beamline;250 J,ns regime beamline)based on Nd:glass amplification.Its pulse duration(20 times shorter)combined with the system design will allow the auxiliary beamline and its secondary sources to be used as probe beams for longer pulses and their interactions with targets.The newly designed system will be mainly dedicated to electron beam generation,but could also be used to perform a variety of particle acceleration and optical radiation detection experimental campaigns.In this communication,we present the entire beamline design discussing the technology choices and the design supported by extensive simulations for each system section.Finally,we present experimental results and details of our commissioned NOPCPA picosecond front end,delivering 1.5 mJ,~180 nm(1/e^(2))of bandwidth compressed to sub-15 fs.Mario Galletti Pedro Oliveira Marco Galimberti Munadi Ahmad Giedre Archipovaite Nicola Booth Emerald Dilworth Andy Frackiewicz Trevor Winstone Ian Musgrave Cristina Hernandez-Gomez 2020High Power Laser Science and Engineering2020,8,4:2
