1Nitrate Transport, Sensing, and Responses in Plants显示文摘氮(N) 是影响植物生长和开发的必要 macronutrient。N 是叶绿素,氨基酸, nucleic 酸,和第二等的代谢物的一个重要部件。硝酸盐是在土壤的最丰富的 N 来源之一。因为硝酸盐和其它 N 营养素经常正在限制,植物开发了复杂机制在可变环境保证营养素的足够的供应。硝酸盐全神贯注于根并且由硝酸盐 transporters 动员了到另外的机关。硝酸盐察觉到激活局部地并且在整个植物水平在分子、新陈代谢、生理、发展的回答之上侵犯的发信号的小径。与 genomics 技术和基因工具的来临,在我们硝酸盐和另外的 N 滋养的回答的理解的重要进展在过去的十年被完成了。而且,从单个种利用在分叉的个人在场的自然多型性的技术在揭开是必要的新部件。然而,仍然在我们硝酸盐发信号怎么在植物影响生物过程的理解有差距。而且,我们仍然缺乏识别的所有规章的因素怎么交往的一个综合看法或串音安排植物典型地展出的无数 N 回答。在这评论,我们提供由哪个硝酸盐全部被察觉到并且搬运植物的机制的更新的概述。我们讨论发信号的部件并且怎么在植物局部地并且全球性为发展回答与神经质的小径察觉到串音的硝酸盐。理解硝酸盐怎么在植物影响植物新陈代谢,生理学,和生长和开发对为持续农业改进庄稼关键。Jose A.

2Integration of Probabilistic and Multi-Hazard Risk Assessment Within Urban Development Planning and Emergency Preparedness and Response: Application to Manizales,Colombia显示文摘The details of a multi-hazard and probabilistic risk assessment, developed for urban planning and emergency response activities in Manizales, Colombia, are presented in this article. This risk assessment effort was developed under the framework of an integral disaster risk management project whose goal was to connect risk reduction activities by using open access and state-of-theart risk models. A probabilistic approach was used for the analysis of seismic, landslide, and volcanic hazards to obtain stochastic event sets suitable for probabilistic loss estimation and to generate risk results in different metrics after aggregating in a rigorous way the losses associated to the different hazards. Detailed and high resolution exposure databases were used for the building stock and infrastructure of the city together with a set of vulnerability functions for each of the perils considered. The urban and territorial ordering plan of the city was updated for socioeconomic development and land use using the hazard and risk inputs and determinants, which cover not only the current urban area but also those adjacent areas where the expansion of Manizales is expected to occur. The emergency response capabilities of the city were improved by taking into account risk scenarios and after updating anautomatic and real-time post-earthquake damage assessment.Gabriel A.Bernal Mario A.Salgado-Gálvez Daniela Zuloaga Julián Tristancho Diana González Omar-Darío Cardona 2017International Journal of Disaster Risk Science2017,8,3:4
3Automatic Detection of COVID-19 Infection Using Chest X-Ray Images Through Transfer Learning显示文摘The new coronavirus(COVID-19),declared by the World Health Organization as a pandemic,has infected more than 1 million people and killed more than 50 thousand.An infection caused by COVID-19 can develop into pneumonia,which can be detected by a chest X-ray exam and should be treated appropriately.In this work,we propose an automatic detection method for COVID-19 infection based on chest X-ray images.The datasets constructed for this study are composed of194 X-ray images of patients diagnosed with coronavirus and 194 X-ray images of healthy patients.Since few images of patients with COVID-19 are publicly available,we apply the concept of transfer learning for this task.We use different architectures of convolutional neural networks(CNNs)trained on Image Net,and adapt them to behave as feature extractors for the X-ray images.Then,the CNNs are combined with consolidated machine learning methods,such as k-Nearest Neighbor,Bayes,Random Forest,multilayer perceptron(MLP),and support vector machine(SVM).The results show that,for one of the datasets,the extractor-classifier pair with the best performance is the Mobile Net architecture with the SVM classifier using a linear kernel,which achieves an accuracy and an F1-score of 98.5%.For the other dataset,the best pair is Dense Net201 with MLP,achieving an accuracy and an F1-score of 95.6%.Thus,the proposed approach demonstrates efficiency in detecting COVID-19 in X-ray images.Elene Firmeza Ohata Gabriel Maia Bezerra João Victor Souza das Chagas Aloísio Vieira Lira Neto Adriano Bessa Albuquerque Victor Hugo Cde Albuquerque Pedro Pedrosa Rebouças Filho 2021IEEE/CAA Journal of Automatica Sinica2021,8,1:3
4Probabilistic Seismic Risk Assessment in Manizales,Colombia: Quantifying Losses for Insurance Purposes显示文摘A fully probabilistic seismic risk assessment was developed in Manizales, Colombia, considering assets of different types. The first type includes elements that are part of the water and sewage network, and the second type includes public and private buildings. This assessment required the development of a probabilistic seismic hazard analysis that accounts for the dynamic soil response,assembling high resolution exposure databases, and the development of damage models for different types of elements. The economic appraisal of the exposed assets was developed together with specialists of the water utilities company of Manizales and the city administration. The risk assessment was performed using several Comprehensive Approach to Probabilistic Risk Assessment modules as well as the R-System, obtaining results in terms of traditional metrics such as loss exceedance curve, average annual loss, and probable maximum loss. For the case of pipelines, repair rates were also estimated. The results for the water and sewage network were used in activities related to the expansion and maintenance strategies, as well as for the exploration of financial retention and transfer alternatives using insurance schemes based on technical,probabilistic, and prospective damage and loss estimations.In the case of the buildings, the results were used in the update of the technical premium values of the existing collective insurance scheme.Mario A.
