| 1 | Air quality monitoring using mobile microscopy and machine learning显示文摘Rapid,accurate and high-throughput sizing and quantification of particulate matter(PM)in air is crucial for monitoring and improving air quality.In fact,particles in air with a diameter of≤2.5μm have been classified as carcinogenic by the World Health Organization.Here we present a field-portable cost-effective platform for high-throughput quantification of particulate matter using computational lens-free microscopy and machine-learning.This platform,termed c-Air,is also integrated with a smartphone application for device control and display of results.This mobile device rapidly screens 6.5 L of air in 30 s and generates microscopic images of the aerosols in air.It provides statistics of the particle size and density distribution with a sizing accuracy of~93%.We tested this mobile platform by measuring the air quality at different indoor and outdoor environments and measurement times,and compared our results to those of an Environmental Protection Agency–approved device based on beta-attenuation monitoring,which showed strong correlation to c-Air measurements.Furthermore,we used c-Air to map the air quality around Los Angeles International Airport(LAX)over 24 h to confirm that the impact of LAX on increased PM concentration was present even at 47 km away from the airport,especially along the direction of landing flights.With its machinelearning-based computational microscopy interface,c-Air can be adaptively tailored to detect specific particles in air,for example,various types of pollen and mold and provide a cost-effective mobile solution for highly accurate and distributed sensing of air quality. | Yi-Chen Wu Ashutosh Shiledar Yi-Cheng Li Jeffrey Wong Steve Feng Xuan Chen Christine Chen Kevin Jin Saba Janamian Zhe Yang Zachary Scott Ballard Zoltán Göröcs Alborz Feizi Aydogan Ozcan | 2017 | Light(Science & Applications)2017，6，1： | 5 |
| 2 | 运用卫星数据和来自国家森林清查的野外数据进行全国森林变量估计显示文摘瑞典约有55%的土地面积被森林所覆盖。目前,瑞典的森林覆盖没有统一的和地理学上明晰的描述。现存的独立性数据源是Landsat TM和SPOT HRV卫星数据、地图蒙片(map mask)和森林清查样地。它们在一起,使森林变量(如材积和林分年龄)的计算机估计成为可能。这些估计的精确度在像素水平上是低的,但在林分水平上较高。在规划木材资源应如何加以利用或出于监测目的时,这类基于栅格的森林数据对政府来说是有帮助的。本文描述了以有效成本建立森林变量估计全国数据库的生成流程。我们在林分水平上评价了瑞典西南部某地森林变量估计的精确度。结果表明,总材积估计的整体均方根误差为33%,年龄估计的整体均方根误差为23%。 | Heather Reese Mats Nilsson Tina Granqvist Pahlén Olle Hagner Steve Joyce Ulf Tingelf Mikael Egberth Hkan Olsson 王胜 | 2003 | AMBIO-人类环境杂志2003，32，8： | 4 |
| 3 | B lymphocytes regulate airway granulocytic inflammation and cytokine production in a murine model of fungal allergic asthma显示文摘到真菌的促进感受性经常导致是特别地困难的临床上设法的气喘的一种严重形式,导致在这些病人的增加的病态和住院。尽管 B 淋巴细胞可能通过 IgE 的生产加重气喘症状,这些房间可能也在对吸入的真菌的保护的反应是重要的。通过 cytokine 版本和 T 房间相互作用,这些淋巴细胞可能也影响航线墙纤维变性的发展和维护。J H −/− 老鼠为抗体的重链部件缺乏 JH 基因,它为 B 房间功能和幸存是批评的。这些动物在很多有免疫力的回答便于 B 淋巴细胞的角色的说明;然而, J H −/− 老鼠没被用来学习真菌的过敏症。在这研究,我们用曲霉属菌 fumigatus 检验了 B 淋巴细胞的角色模仿被环境真菌的暴露触发的人的航线疾病的鼠科的真菌的高空过敏症模型。我们在敏化的野类型的 BALB/c 和 J 暴露于的 H −/− 老鼠重复了真菌的暴露并且没在大航线附近在航线 hyperresponsiveness,全面肺的发炎或骨胶原免职发现差别。然而, Th2 类型 cytokines IL-4 和 IL-13 的层次显著地在 J 相对 BALB/c 控制的 H −/− 鼠标。由对比,煽动性的 cytokines IL-17A 和 IL-6 的层次显著地在 J H −/− 动物,并且有显著地更柔韧的航线嗜曙红血球过多和 neutrophilia 比在控制动物。一起拿,这些调查结果表明淋巴细胞帮助在肺的分隔空间调整 granulocytic 回答到真菌的暴露的那 B。 | Sumit Ghosh Scott A Hoselton Scott V Asbach Breanne N Steffan Steve B Wanjara Glenn P Dorsam Jane M Schuh | 2015 | Cellular & Molecular Immunology2015，12，2： | 2 |
