Achieving high maize yields and efficient phosphorus(P)use with limited environmental impacts is one of the greatest challenges in sustainable maize *** plant density is considered an effective approach for achieving high maize ***,the low mobility of P in soils and the scarcity of natural P resources have hindered the development of methods that can simultaneously optimize P use and mitigate the P-related environmental footprint at high plant *** this study,meta-analysis and substance flow analysis were conducted to evaluate the effects of different types of mineral P fertilizer on maize yield at varying plant densities and assess the flow of P from rock phosphate mining to P fertilizer use for maize production in China.A significantly higher yield was obtained at higher plant densities than at lower plant *** application of single superphosphate,triple super-phosphate,and calcium magnesium phosphate at high plant densities resulted in higher yields and a smaller environmental footprint than the application of diammonium phosphate and monoammonium *** scenario analyses suggest that combining the optimal P type and application rate with a high plant density could increase maize yield by 22%.Further,the P resource use efficiency throughout the P supply chain increased by 39%,whereas the P-related environmental footprint decreased by 33%.Thus,simultaneously optimizing the P type and application rate at high plant densities achieved multiple objectives during maize production,indicating that combining P management with cropping techniques is a practical approach to sustainable maize *** findings offer strategic,synergistic options for achieving sustainable agricultural development.

Protein-mediated chromatin interactions can be revealed by coupling proximity-based ligation with chromatin ***,these techniques require complex experimental procedures and millions of cells per experiment,which limits their widespread application in life science ***,we develop a novel method,Hi-Tag,that identifies high-resolution,long-range chromatin interactions through transposase tagmentation and chromatin proximity ligation(with a phosphorothioate-modified linker).Hi-Tag can be implemented using as few as 100,000 cells,involving simple experimental procedures that can be completed within 1.5 ***,Hi-Tag is capable of using its own data to identify the binding sites of specific proteins,based on which,it can acquire accurate interaction *** results suggest that Hi-Tag has great potential for advancing chromatin interaction studies,particularly in the context of limited cell availability.

近年来,阻尼力与位移呈线性关系的新型调谐质量阻尼器(Tuned mass damper, TMD)相继出现,其参数分析优化原理大部分属于动力数值分析缺乏理论参数优化指导。该文对白噪声作用下具有上述特性的TMD,即滞变阻尼调谐质量阻尼器(Hysteretic damping tuned mass damper, HD-TMD)进行减振优化研究。总结了HD-TMD的力学机理并推导出相应的结构-HD-TMD系统运动方程;提出适用于HD-TMD的H_(2)优化和性能平衡设计,并通过数值拟合技术得到了最优参数公式和基于容忍度的性能平衡设计流程;以真实可用的变摩擦摆式调谐质量阻尼器(VFP-TMD)为HD-TMD的实际算例,检验所提出的优化方法对风振激励的减振性能影响。结果表明:H_(2)优化和性能平衡设计下的HD-TMD可以提供略优于传统黏滞阻尼TMD的控制效果。H_(2)优化的最优参数能使HD-TMD发挥最大的潜能从而实现最好的减振率,但面临VFP-TMD行程过大导致的摆动非线性问题。性能平衡设计下的最优参数可以控制VFP-TMD行程在线性范围内,同时发挥出良好且稳定的减振控制效果实现双赢。与最优参数公式结果相比,性能平衡设计的峰值减振率和均方差峰值减振率仅损失3.19%和0.74%。

为探究火灾、经济、环境的时空演化特征,基于2000—2019年中国火灾、经济、环境数据,建立火灾-经济-环境耦合协调模型,研究火灾、经济、环境系统的耦合发展水平;结合探索性空间数据分析(ESDA)方法研究我国31个省域各子系统时空演变特征及聚集性,并基于Moran'I检验开展火灾、经济、环境空间相关性分析。研究结果表明:2000—2019年火灾、经济和环境综合发展耦合良好。从时间维度上,2000—2019年耦合度和协调度呈上升趋势,耦合度受火灾综合得分影响,协调度受经济子系统影响;从空间维度上,经济发展是影响31个省域耦合协调度的主要因素。从耦合关系时空演变分析看,省域耦合度随时间呈聚集状态,耦合协调度在空间聚集中呈随机性。火灾、经济和环境对耦合协调的不同影响,导致协调类型及空间聚集状态不同。

人类对世界的认知体系中,一直存在客观世界与主观世界的二元对立。对于两个世界之间的勾连,很多哲人尝试提出过一些概念。自大众媒介诞生以来,普遍存在的新闻媒介作为一种物质性的中介,构建出新闻世界,在实践中勾连起两个世界。新闻世界的基础是客观世界,即新闻以事实为本源,强调具体事实和整体事实的有机统一;同时,新闻世界构建的是基于客观世界的认知世界,即偏向于主观世界和意义世界。新闻世界物质性地勾连起客观世界与主观世界。新闻世界以构建、调整关系为核心和意义追求,突破了当前新闻学的知识体系所镌刻着工业革命的时代基因以及以文本为核心的底色,为建设中国特色新闻学自主知识体系提供了兼顾普遍和特殊、共时与历时的元概念,亦对反哺哲学和社会科学有所裨益。
