Plant pests and diseases threaten food security by causing over 10%loss of global crops yield.Plant immunity relies on a complex hormonal signaling network in which jasmonates(JAs)play a central role.JAs are fatty acid–derived hormones ubiquitous in the plant kingdom similar to animal prostaglandins,and are essential phytohormones regulating development,environmental adaptation and defense against necrotrophic pathogens and insects in plants.

With the continuous expansion of software applications,people’s requirements for software quality are increasing.Software defect prediction is an important technology to improve software quality.It often encodes the software into several features and applies the machine learning method to build defect prediction classifiers,which can estimate the software areas is clean or buggy.However,the current encoding methods are mainly based on the traditional manual features or the AST of source code.Traditional manual features are difficult to reflect the deep semantics of programs,and there is a lot of noise information in AST,which affects the expression of semantic features.To overcome the above deficiencies,we combined with the Convolutional Neural Networks(CNN)and proposed a novel compiler Intermediate Representation(IR)based program encoding method for software defect prediction(CIR-CNN).Specifically,our program encoding method is based on the compiler IR,which can eliminate a large amount of noise information in the syntax structure of the source code and facilitate the acquisition of more accurate semantic information.Secondly,with the help of data flow analysis,a Data Dependency Graph(DDG)is constructed on the compiler IR,which helps to capture the deeper semantic information of the program.Finally,we use the widely used CNN model to build a software defect prediction model,which can increase the adaptive ability of the method.To evaluate the performance of the CIR-CNN,we use seven projects from PROMISE datasets to set up comparative experiments.The experiments results show that,in WPDP,with our CIR-CNN method,the prediction accuracy was improved by 12%for the AST-encoded CNN-based model and by 20.9%for the traditional features-based LR model,respectively.And in CPDP,the AST-encoded DBNbased model was improved by 9.1%and the traditional features-based TCA+model by 19.2%,respectively.

我们总是尝试在安全距离的范围内跨越“距离”。因此，在建筑设计中，设计师提出要有“公共空间”；在社区之间，邻里提出要使生活更“融洽”；在艺术作品中，艺术家提出要超越现实同时又接近“真实”。而这些，在“美丽的阶梯”这一艺术作品中得以完美展现。艺术家萨比拉·朗（Sabina Lang）和丹尼尔·鲍曼（Daniel Baumann）巧妙地运用不同的衔接方式将白色的阶梯与建筑物、建筑空间结合在一起。

The Buyi are a socio-linguistic group in Yunnan Province of southwest China that have a long history of using medicinal plants as part of their indigenous medical system.Given the limited written documentation of the Buyi indigenous medical system,the objective of this paper is to document the medicinal plants of the Buyi and associated traditional knowledge and transmission.Field research was conducted in four villages in Lubuge Township of Luoping County in Yunnan Province using ethnobotanical methodologies including participatory observation,semi-structured interviews,key informant interviews,and focus group discussions to elicit information on medicinal plants.In total,120 informants(including 15 key informants who are healers)were interviewed.This study found that a total of 121 medicinal plant species belonging to 64 families are used by the Buyi including by local healers to treat different diseases.Among the medicinal plants recorded in this study,56 species(46%)have not previously been documented in the scientific literature as having medicinal value,highlighting the pressing need for ethnobotanical documentation in indigenous communities.The most frequently used medicinal part was the leaf(24.9%of documented plants),and the most common preparation method was decoction(62.8%of medicinal).Medicinal plants were mainly used to treat rheumatism(12.4%of plants),trauma and injuries(9.6%).The documented plants are also used for other non-medicinal purposes including food,fodder,fencing,and ornamental.In addition,35 of the medicinal plants are considered poisonous and are used by local Buyi healers for medicine.The traditional Buyi beliefs and practices associated with the documented medicinal plants likely contributes to their conservation in the environments and around Buyi communities.This study further highlights that ethnomedicinal knowledge of the Buyi is at risk of disappearing due to increased introduction and use of modern medicine in Buyi communities,livelihood changes,rapid modernization,and urbanizat

Animals use diverse sensory stimuli to navigate their environment and to recognize rewarding food sources.Honey bees use visual atributes of the targeted food source,such as its color,shape,size,direction and distance from the hive,and the landmarks around it to navigate during foraging.They transmit the location information of the food source to other bees if it is highly rewarding.To investigate the relative importance of these attributes,we trained bees to feeders in two different experiments.In the first experiment,we asked whether bees prefer to land on(a)a similar feeder at a different distance on the same heading or on(b)a visually distinct feeder located at the exact same location.We found that,within a short foraging range,bees relied heavily on the color and the shape of the food source and to a lesser extent on its distance from the hive.In the second experiment,we asked if moving the main landmark or the feeder(visual target)influenced recruitment dancing for the feeder.We found that foragers took longer to land and danced fewer circuits when the location of the food source,or a major landmark associated with it,changed.These results demonstrate that prominent visual atributes of food sources and landmarks are evidently more reliable than distance information and that foraging bees heavily utilize these visual cues at the later stages of their journey.
