| 1 | Forage 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 | 2022 | Grassland Research2022，1，3： | 0 |
| 2 | Bridging the Divide Between Iterative Optical Polishing and Automation显示文摘Several recent business reports have described the global growth in demand for optical and photonic components,paralleled by technical reports on the growing shortage of skilled manufacturing staff to meet this demand.It is remarkable that producing ultraprecision surfaces remains so dependent on people,in contrast to other sectors of the economy,e.g.,car manufacturing.Clearly,training can play some role,but ultimately,only process automation can provide the solution.This paper explores why automation is a challenge and summarizes multidisciplinary work aiming to assemble the building blocks required to realize automation. | David Walker Juan I.Ahuir‑Torres Yasemin Akar Paul A.Bingham Xun Chen Michal Darowski Oliver Fähnle Philippe Gambron Frankie F.Jackson Hongyu Li Luke Mason Rakesh Mishra Abdullah Shahjalal Guoyu Yu | 2023 | Nanomanufacturing and Metrology2023，6，3： | 0 |
| 3 | 师生关系和学生学业表现相辅相成显示文摘在从小学到大学十几年的学习生涯中,我们多多少少会发出过以下感叹:教师们怎么都喜欢学习好的学生?学习好的学生好像都和教师关系挺好的?究竟师生关系影响学生学业表现,还是学生学业表现影响师生关系,抑或两者之间互为因果? | Mason,Benjamin A. Hajovsky,Daniel B. McCune,Luke A. Turek,Joshua J. 郭慧丹(编译) 雷雳(编译) | 2018 | 基础教育参考2018，9，21： | 0 |
