Non-alcoholic fatty liver disease(NAFLD)and type 2 diabetes mellitus(T2DM)are two disease conditions for which obesity is a risk factor.^(1)Due to the close relationship between the three pathologies,researchers frequently use the same mouse models to identify the underlying processes of obesity,NAFLD,and *** instance,leptin(Lep)-null(ob/ob)and leptin receptor(Lepr)-deficient(db/db)mice spontaneously develop NAFLD and show different phenotypes of extreme obesity and diabetes,respectively.

Source code management systems (such as git) record changes to code repositories of Open-Source Software (OSS) projects. The metadata about a change includes a change message to record the intention of the change. Classification of changes, based on change messages, into different change types has been explored in the past to understand the evolution of software systems from the perspective of change size and change density only. However, software evolution analysis based on change classification with a focus on change evolution patterns is still an open research problem. This study examines change messages of 106 OSS projects, as recorded in the git repository, to explore their evolutionary patterns with respect to the types of changes performed over time. An automated keyword-based classifier technique is applied to the change messages to categorize the changes into various types (corrective, adaptive, perfective, preventive, and enhancement). Cluster analysis helps to uncover distinct change patterns that each change type follows. We identify three categories of 106 projects for each change type: high activity, moderate activity, and low activity. Evolutionary behavior is different for projects of different categories. The projects with high and moderate activity receive maximum changes during 76-81 months of the project lifetime. The project attributes such as the number of committers, number of files changed, and total number of commits seem to contribute the most to the change activity of the projects. The statistical findings show that the change activity of a project is related to the number of contributors, amount of work done, and total commits of the projects irrespective of the change type. Further, we explored languages and domains of projects to correlate change types with domains and languages of the projects. The statistical analysis indicates that there is no significant and strong relation of change types with domains and languages of the 106 proje

Tropospheric pollutants including surface ozone（O3）, nitrogen dioxide（NO2）, carbon monoxide（CO） and meteorological parameters were measured at a traffic junction（78°2′ E and 27°11′ N） in Agra, India from January 2012 to December 2012. Temporal analysis of pollutants suggests that annual average mixing ratios of tropospheric pollutants were： O3— 22.97 ± 23.36 ppbV,NO2— 19.84 ± 16.71 ppb V and CO — 0.91 ± 0.86 ppm V, with seasonal variations of O3 having maximum mixing ratio during summer season（32.41 ± 19.31 ppbV）, whereas lowest was found in post-monsoon season（8.74 ± 3.8 ppbV）. O3 precursors： NO2 and CO, showed inverse relationship with O3. Seasonal variation and high O3 episodes during summer are associated with meteorological parameters such as high solar radiation, atmospheric temperature and transboundary transport. The interdependence of these variables showed a link between the daytime mixing ratios of O3 with the nighttime level of NO2. The mixing ratios of CO and NO2 showed tight correlations, which confirms the influence of vehicular emissions combined with other anthropogenic activities due to office/working hours, shallowing, and widening of boundary layer. FLEXTRA backward trajectories for the O3 episode days clearly indicate the transport from the NW and W to S/SE and SW direction at Agra in different seasons.

Reticulated foam shaped adsorbents are more efficient for the removal of volatile organic compounds（VOCs）,particularly from low VOC-concentration indoor air streams. In this study composite structure of zeolite and metal organic frameworks（MOFs）,referred as ZMF,has been fabricated by immobilization of fine MOF-199 powder on foam shaped Zeolite Socony Mobil-5（ZSM-5）Zeolitic structure,referred as ZF. The ZMF possess a uniform and well-dispersed coating of MOF-199 on the porous framework of ZF. It shows higher surface area,pore volume,and VOCs adsorption capacity,as compared to ***-fabrication changes in selective adsorption properties of ZMF were studied with three common indoor VOCs（benzene,n-hexane,and cyclohexane）,using gravimetric adsorption technique. The adsorption capacity of ZMF with different VOCs follow the order of benzene 〉 n-hexane 〉 cyclohexane. In comparison with MOF-199 and ZF,the composite structure ZMF shows improvement in selectivity for benzene from other two VOCs. Further,improvement in efficiency and stability of prepared ZMF was found to be associated with its high MOF loading capacity and unique morphological and structural properties. The developed composite structure with improved VOCs removal and recyclability could be a promising material for small to limited scale air pollution treatment units.

海运业对国际贸易和经济增长至关重要,其中80%的全球贸易是由海洋运输的。但是,船舶数量的增加导致越来越多的海运事故的发生,造成人员伤亡,经济和环境破坏。为了预防事故的发生,并协助搜查和救援,船舶轨迹预测变得越来越重要。本研究中,提出两种方法来解决船舶轨迹预测问题,分别是新的Transformer网络架构和新的聚类增强方法。1)提出新的Transformer网络架构,结合自动识别系统(AIS)数据进行水下机器人(AUVs)的轨迹预测任务。提出一个综合性实验来验证本文提出的网络的性能。将实验结果与其他最新的预测模型进行比较,以预测固定和可变输入和输出长度的AUV的未来位置。结果表明,该Transformer模型的性能显著超过其他模型。2)提出一种解决路点导航问题的新方法。将数据聚类技术引入常规轨迹预测管道。利用DBSCAN算法来识别航点模式,然后再将其送入NN模型。将这种技术应用于轻量级的LSTM模型,用于航点导航。该聚类方法有助于将AIS数据中的模式和相似的轨迹融合在一起识别,从而增强LSTM模型准确预测未来位置的能力。该聚类方法还有助于识别AIS数据中的类似的轨迹,这又可以增强LSTM模型准确预测未来位置的能力。
