The productivity, product quality and competitive ability of important agricultural and horticultural plants in many regions of the world may be adversely affected by current and anticipated concentrations of ground-level ozone （O_3）. Exposure to elevated O_3 typically results in suppressed photosynthesis, accelerated senescence, decreased growth and lower yields. Various approaches used to evaluate O_3 effects generally concur that current yield losses range from 5% to 15% among sensitive plants. There is, however, considerable genetic variability in plant responses to O_3.

川东北元坝地区千佛崖组二段半深湖相页岩具有良好的页岩油气勘探前景。通过层序划分,对页岩岩相发育特征进行研究,对不同页岩岩相控制下的储层特征进行分析,明确准层序格架下不同页岩岩相的成因及对储层发育的影响。研究结果表明:千佛崖组二段可划分为7个准层序,根据准层序内的沉积特征,可将准层序划分为湖侵旋回为主型、湖退旋回为主型和均衡型3种不同的沉积模式。千佛崖组二段页岩发育有纹层状页岩相、层状页岩相和块状页岩相三种主要岩相类型,纹层状页岩相整体孔隙更发育,连通性更好,储集物性更好;层状页岩相整体孔隙发育程度和储集物性较纹层状页岩相次之;块状页岩相孔隙发育情况不佳,连通性一般,物性较差。页岩储层受岩相影响呈现出不同的特征,页岩岩相的纵向演化明显受准层序的控制,不同准层序类型的页岩岩相发育特征存在明显差异。整体来看,优质储层在最大洪泛面附近更为发育,优质页岩储层主要发育在湖侵旋回为主型准层序的中上部,有机质富集、孔隙发育且连通性好,是下一步勘探的有利目标;湖退旋回为主型准层序的中下部发育次优储层。

Malaria is an important and worldwide fatal disease that has been widely reported by the World Health Organization(WHO),and it has about 219 million cases worldwide,with 435,000 of those mortal.The common malaria diagnosis approach is heavily reliant on highly trained experts,who use a microscope to examine the samples.Therefore,there is a need to create an automated solution for the diagnosis of malaria.One of the main objectives of this work is to create a design tool that could be used to diagnose malaria from the image of a blood sample.In this paper,we firstly developed a graphical user interface that could be used to help segment red blood cells and infected cells and allow the users to analyze the blood samples.Secondly,a Feed-forward Neural Network(FNN)is designed to classify the cells into two classes.The achieved results show that the proposed techniques can be used to detect malaria,as it has achieved 92%accuracy with a database that contains 27,560 benchmark images.

Complex sustainability issues in the Anthropocene,with rapid globalization and global environmental changes,are increasingly interlinked between not only nearby systems but also distant systems.Tobler’s first law of geog-raphy(TFL)states“near things are more related than distant things”.Evidence suggests that TFL is not infallible for sustainability issues.Recently,the integrated framework of metacoupling(MCF;human-nature interactions within as well as between adjacent and distant systems)has been applied to analyze the interactions between nearby and distant coupled human and natural systems simultaneously.However,previous work has been scat-tered and fragmented.It is crucial to understand the extent to which TFL and MCF apply across pressing issues in sustainability.Therefore,we reviewed and synthesized sustainability literature that used TFL and MCF across seven major topics:land change,species migration,tourism,trade,agricultural development,conservation,and governance.Results indicate MCF had a much broader applicability than TFL for these topics.The literature using MCF generally did not or likely did not obey TFL,especially in trade,governance,and agricultural de-velopment.In the TFL literature,most topics obeyed TFL,except for species migration and trade.The findings suggest the need to rethink and further test TFL’s relevance to sustainability issues,and highlight the potential of MCF to address complex interactions between both adjacent and distant systems across the world for global sustainability.

The accumulation of pollutants in the recirculation zone can worsen ventilation.It is critical to reduce recirculation zones to improve the ventilation efficiency of buildings.However,the variation rule of the recirculation zone in a cylindrical confined space(CCS)is unclear,and there are few solutions to suppress or eliminate the recirculation zone at present.In this paper,an annular deflector orifice plate for suppressing the recirculation zone was developed based on the structural characteristics of the CCS.This device is simple in structure and can be used flexibly.Through experiments and numerical simulations,the variation rule of the recirculation zone length and the influence of structural parameters of the device on the vortex suppression were explored.Firstly,empirical formulas for calculating the length of the recirculation zone in the CCS were obtained.In addition,it was proved that placing the annular orifice plate inside the CCS effectively reduced the recirculation zone and improved the ventilation efficiency.Compared to the system without the annular orifice plate,the dimensionless length of the recirculation zone was decreased by 76.3%,and the time to completely discharge the pollutants from the CCS was decreased by 16.7%.Finally,parameters of the annular orifice plate that form the best vortex suppression effect were proposed:the porosity range was 40%–50%,uniform in shape with equal ring spacing,and placed more than one inlet diameter away from the inlet.The results help guide the ventilation design of CCS.

1 Introduction Deep neural networks have exhibited excellent performance in supervised tasks on point clouds,such as classification,segmentation[1]and registration[2].In supervised learning schemes,manual labeling of massive point clouds is needed for model training.However,point clouds captured from different scenarios exist inevitable distribution discrepancy,and model trained from one domain always generalize badly in another domain.To reduce the doamin distribution discrepancy,many studies[3–6]have emerged for point cloud unsupervised domain adaptation(UDA)by learning domain-invariant features,where[5]proposed using adaptive nodes to align the local features between the source and the target domains[3,4],and[6]proposed utilizing self-supervised tasks to help capture highly transferable feature representations.

J apanese larch(La rix kaempferi(Lamb.) Carr.)and its hybrid are economically important coniferous trees widely grown in the Northern Hemisphere.Ground-level ozone(O3) concentrations have increased since the preindustrial era,and research projects showed that Japanese larch is susceptible to elevated O3exposures.Therefore,methodologies are needed to(1) protect Japanese larch against O3damage and(2) conduct biomonitoring of O3in Japanese larch forests and,thus,monitor O3risks to Japanese larch.For the first time,this study evaluates whether the synthetic chemical ethylenediurea(EDU) can protect Japanese larch against O3damage,in two independent experiments.In the first experiment,seedling communities,simulating natural regeneration,were treated with EDU(0,100,200,and 400 mg L-1) and exposed to either ambient or elevated O3in a growing season.In the second experiment,individually-grown saplings were treated with EDU(0,200 and 400 mg L-1) and exposed to ambient O3in two growing seasons and to elevated O3in the succeeding two growing seasons.The two experiments revealed that EDU concentrations of 200-400 mg L-1could protect Japanese larch seedling communities and individual saplings against O3-induced inhibition of growth and productivity.However,EDU concentrations ≤200 mg L-1did offer only partial protection when seedling communities were coping with higher level of O3-induced stress,and only 400 mg EDU L-1fully protected communities under higher stress.Therefore,we conclude that among the concentrations tested the concentration offering maximum protection to Japanese larch plants under high competition and O3-induced stress is that of 400 mg EDU L-1.The results of this study can provide a valuable resource of information for applied forestry in an O3-polluted world.
