1Combining computer vision and deep learning to enable ultra-scale aerial phenotyping and precision agriculture:A case study of lettuce production显示文摘Aerial imagery is regularly used by crop researchers,growers and farmers to monitor crops during the growing season.To extract meaningful information from large-scale aerial images collected from the field,high-throughput phenotypic analysis solutions are required,which not only produce high-quality measures of key crop traits,but also support professionals to make prompt and reliable crop management decisions.Here,we report AirSurf,an automated and open-source analytic platform that combines modern computer vision,up-to-date machine learning,and modular software engineering in order to measure yield-related phenotypes from ultra-large aerial imagery.To quantify millions of in-field lettuces acquired by fixed-wing light aircrafts equipped with normalised difference vegetation index(NDVI)sensors,we customised AirSurf by combining computer vision algorithms and a deep-learning classifier trained with over 100,000 labelled lettuce signals.The tailored platform,AirSurf-Lettuce,is capable of scoring and categorising iceberg lettuces with high accuracy(>98%).Furthermore,novel analysis functions have been developed to map lettuce size distribution across the field,based on which associated global positioning system(GPS)tagged harvest regions have been identified to enable growers and farmers to conduct precision agricultural practises in order to improve the actual yield as well as crop marketability before the harvest.Alan Bauer Aaron George Bostrom Joshua Ball Christopher Applegate Tao Cheng Stephen Laycock Sergio Moreno Rojas Jacob Kirwan Ji Zhou 2019Horticulture Research2019,6,1:14

8采用碳化硅包壳的高燃耗压水堆堆芯设计显示文摘1引言 50多年来,对于轻水堆的燃料棒,锆合金一直都被用作安全而可靠的包壳材料。虽然这种材料已很成功,但核工业界现在又有一项有关碳化硅(SiC)研究的新提议,计划研究超越锆的燃耗限值62MW·d/kg(U)。SiC是一种坚固的陶瓷包壳材料,有可能会成为超过传统锆合金的改进材料。Jacob P. Dobisesky Joshua G. Richard Edward E.Pilat 兰洋(译) 2012国外核动力2012,33,2:1
93D microfluidic gradient generator for combination antimicrobial susceptibility testing显示文摘Microfluidic concentration gradient generators(µ-CGGs)have been utilized to identify optimal drug compositions through antimicrobial susceptibility testing(AST)for the treatment of antimicrobial-resistant(AMR)infections.Conventionalµ-CGGs fabricated via photolithography-based micromachining processes,however,are fundamentally limited to two-dimensional fluidic routing,such that only two distinct antimicrobial drugs can be tested at once.This work addresses this limitation by employing Multijet-3D-printed microchannel networks capable of fluidic routing in three dimensions to generate symmetric multidrug concentration gradients.The three-fluid gradient generation characteristics of the fabricated 3Dµ-CGG prototype were quantified through both theoretical simulations and experimental validations.Furthermore,the antimicrobial effects of three highly clinically relevant antibiotic drugs,tetracycline,ciprofloxacin,and amikacin,were evaluated via experimental single-antibiotic minimum inhibitory concentration(MIC)and pairwise and three-way antibiotic combination drug screening(CDS)studies against model antibiotic-resistant Escherichia coli bacteria.As such,this 3Dµ-CGG platform has great potential to enable expedited combination AST screening for various biomedical and diagnostic applications.Eric Sweet Brenda Yang Joshua Chen Reed Vickerman Yujui Lin Alison Long Eric Jacobs Tinglin Wu Camille Mercier Ryan Jew Yash Attal Siyang Liu Andrew Chang Liwei Lin 2020Microsystems & Nanoengineering2020,6,1:1

19Forage production and persistence characteristics of grazed native warm-season grass mixtures with or without nitrogen fertilizer显示文摘Background:Native warm-season grass(NWSG)mixtures may provide a lownitrogen(N)-input summer perennial forage option to extensively managed forage-livestock systems.Methods:Mixed pastures of big bluestem(Andropogon gerardii Vitman),little bluestem(Schizachyrium scoparium Michx.),and indiangrass(Sorghastrum nutans L.)fertilized with 0 or 67 kgNha−1 were continuously stocked with beef heifers and cows.Forage mass,nutritive value,and canopy heights were determined every 2 weeks during the grazing season.Stand persistence measures included the canopy cover and leaf area index(LAI)and plant crown density at spring emergence following 3 years of grazing management.Results:Forage mass,canopy height,and stocking densities were greater for N-fertilized NWSG than unfertilized NWSG for the first 30 days of the growing season across the 3-year study.Forage NWSG fertilized with N had a greater decrease in LAI during the growing season(51%decrease)than unfertilized NWSG.Spring NWSG plant density estimates following 3 years of grazing did not differ across N management strategies.Conclusions:Forage NWSG mixtures supported superior forage attributes and greater stocking densities early in the grazing season under low-level N than zero-N-input systems and may provide a low-N-input alternative for improved species use in southeastern US forage-livestock systems.Caroline Nicole Chappell Marty Landon Marks Katie Michelle Mason Liliane Severino da Silva Joshua Luke Jacobs Mary Kimberly Mullenix Sandra Leanne Dillard Russell Brian Muntifering 2022Grassland Research2022,1,3:0
20Calibration after bootstrap for accurate uncertainty quantification in regression models显示文摘Obtaining accurate estimates of machine learning model uncertainties on newly predicted data is essential for understanding the accuracy of the model and whether its predictions can be trusted.A common approach to such uncertainty quantification is to estimate the variance from an ensemble of models,which are often generated by the generally applicable bootstrap method.In this work,we demonstrate that the direct bootstrap ensemble standard deviation is not an accurate estimate of uncertainty but that it can be simply calibrated to dramatically improve its accuracy.We demonstrate the effectiveness of this calibration method for both synthetic data and numerous physical datasets from the field of Materials Science and Engineering.The approach is motivated by applications in physical and biological science but is quite general and should be applicable for uncertainty quantification in a wide range of machine learning regression models.Glenn Palmer Siqi Du Alexander Politowicz Joshua Paul Emory Xiyu Yang Anupraas Gautam Grishma Gupta Zhelong Li Ryan Jacobs Dane Morgan 2022npj Computational Materials2022,,1:0
