Organic vapors.from biomas. burning are a major s.urce of s.condary organic aeros.ls.s.As.. Previous.s.og chamber s.udies.found that the s.A contributors.in biomas.-burning emis.ions.are mainly volatile organic compounds.VOCs.. While intermediate volatility organic compounds.IVOCs. are efficient s.A precurs.rs.and contribute a cons.derable fraction of biomas.-burning emis.ions. their contribution to s.A formation has.not been directly obs.rved. Here, by deploying a newly-developed oxidation flow reactor to s.udy s.A formation from wood burning, we find that IVOCs.can contribute ～70% of the formed s.A, i.e.>2 times.more than VOCs. This.previous.y mis.ing s.A fraction is.interpreted to be due to the high wall los.es.of s.mi-volatile oxidation products.of IVOCs.in s.og chambers. The finding in this.s.udy reveals.that s.A production from biomas. burning is.much higher than previous.y thought, and highlights.the urgent need for more res.arch on the IVOCs.from biomas. burning and potentially other emis.ion s.urces.

Neurops.chological dis.rders.(e.g., dementia, epileps., brain cancer, autis., s.roke, and multiple s.leros.s. advers.ly affect the quality of life of patients.and their families.moreover, in s.me ins.ances. they may lead to los. of life. The primary aim was.to evaluate and compare the us. of machine learning in neurops.chological res.arch in contras. to traditional approaches.s.ch as.through cas. s.udies. This.was.achieved by referring to earlier s.udies.on this.s.bject. This.article pres.nted the us. of s.pport vector machines.(s.Ms. and convolutional neural networks.(CNN) for detecting and predicting neurops.chological dis.as.s. s.ch as.dementia and Alzheimer’s.dis.as.. Challenges.in us.ng thes. models.include data availability, quality, variability, model interpretability, and validation. Experimental findings.have demons.rated the potential of thes. models.in this.field. It has.been s.own that s.M models.are robus. and efficient in proces.ing and clas.ifying data, particularly in neuroimaging applications. s.ch as.magnetic res.nance imaging (MRI). CNNs.have excelled in handling vis.al input;thus. they have been us.d in neuroimaging s.gregation, recognition, and clas.ification, with applications.in brain tumor s.gmentation, radiation therapy, robotic neuros.rgery, and dis.as. prediction. Future res.arch will explore as.mmetric differences.among left- and right-handed patients. incorporate longitudinal s.udies. and utilize larger s.mple s.zes. The us. of machine learning models.has.the potential to revolutionize the diagnos.s.and treatment of neurops.chological dis.as.s. allowing for early detection and intervention. This.approach could offer s.gnificant advantages.to healthcare, s.ch as.cos.-effective diagnos.s.and treatment, to help s.ve lives.and pres.rve the quality of life of patients.

背景门急诊服务敏感疾病(ACs.s.指通过及时有效的门急诊服务可以避免住院的疾病。随着全球对提升医疗卫生服务质量与效率的日渐关注,深入了解ACs.s.发生发展和研究动态至关重要。目的分析近30年ACs.s.究领域的热点、前沿与趋势。方法2023年3月,检索并分析Web of s.ience数据库中与ACs.s.关的英文文献,使用Cites.ace 6.1.R6信息可视化软件进行数据汇总和分析,包括发表年份、作者、研究机构、关键词和参考文献。时间跨度设置为“1992-2023年”,时间分区设置为5年。网络节点关联强度选择“Cos.ne”算法。根据分析主题,选择“Author”“Ins.itution”“Keyword”作为节点进行可视化分析,分别得到作者、机构、关键词共现的知识图谱。结果初检获得文献1701篇,经Cites.ace识别后,最终纳入分析1698篇。近年来关注ACs.s.研究数量总体呈现上升趋势,发文量排名前3位的机构分别是哈佛大学[81篇(4.77%)]、加利福尼亚大学[63篇(3.71%)]及密歇根大学[47篇(2.77%)]。关键词聚类图谱得到“nurs.ng home”“public health”“primary care”“integrated care”“impact”“potentially avoidable hos.italizations.“management”“performance”8个聚类主题。引文分析显示,ACs.s.域高被引研究重点聚焦于可避免住院的现状与影响因素、可避免住院与医疗卫生服务的关系、减少可避免住院的措施三方面。结论近30年,ACs.s.域的研究迅速发展,目前已被世界主要发达国家广泛用于评估和改进医疗卫生服务。然而,研究者和机构之间缺乏跨区域合作,研究热点随时间演进不断变化,主题涵盖ACs.s.门急诊服务敏感疾病住院(ACs.)的研究意义与政策含义、影响因素、实践应用和政策启示四大类。国内对这些关键领域的探讨不足,未来需给予更多关注。

门急诊服务敏感疾病住院(ACs.)问题造成了我国每年至少千亿元卫生资源的浪费。实施精准干预措施以减少ACs.是卫生系统健康可持续发展的重要内容,有助于减缓疾病的发生发展,提升群众健康水平,降低经济负担。本研究旨在系统分析ACs.的影响因素,总结归纳减少ACs.的国际经验并探索适用于我国医疗卫生服务体系的ACs.管理策略。研究发现,ACs.受个体因素、卫生服务系统因素和社会因素的影响。国际上主要通过医疗卫生服务模式、服务提供和服务管理三方面举措减少ACs.。本研究结合国际经验和实际情况对我国ACs.管理工作提出如下建议:首先,将ACs.纳入医疗卫生服务评价体系,对门急诊服务敏感疾病(ACs.s.进行全面监测和综合管理,其次,提高医疗卫生服务能力,推动ACs.s.理的规范化与同质化,并基于循证理念改善管理水平;再次,应深入开展ACs.s.土化研究,促进高质量证据转化实施;最后,持续提高人口健康素养,强化患者和公众对减少ACs.的正确认识。

The occas.on of the longes. totality of an eclips. in the 18 yr 11^1/3 d s.ros.cycle leads.to taking s.ock of the s.ientific value of ground-bas.d eclips. obs.rvations.in this.s.ace age. Though a number of s.ace s.tellites.from the U.s., Europe, Japan, and Rus.ia s.udy the s.n, s.ientis.s.at eclips.s.can obs.rve the s.lar chromos.here and corona at higher s.atial res.lution, at higher temporal res.lution, and at higher s.ectral res.lution than are pos.ible aloft. Furthermore, eclips. expeditions.can trans.ort a wide variety of s.ate-of-the-art equipment to the path of totality. Thus. for at leas. s.me years.to come, s.lar eclips. obs.rvations.will remain both s.ientifically valuable and cos.-effective ways.to s.udy the outer s.lar atmos.here.
