Two indigenous bacteria of petroleum con- taminated soil were characterized to utilize diesel fuel as the sole carbon and energy sources in this work. 16S rRNA gene sequence analysis identified these bacteria as Sphingomonas sp. and Acinetobacterjunii. The ability to degrade diesel fuel has been demonstrated for the first time by these isolates. The results of IR analyses showed that Sphingomonas sp. VA1 and A. junii VA2 degraded up to 82.6% and 75.8% of applied diesel over 15days, respectively. In addition, Sphingomonas sp. VA1 pos- sessed the higher cellular hydrophobicities of 94% for diesel compared to 81% by A. junii VA2. The isolates Sphingomonas sp. VA1 and A. junii VA2 exhibited 24% and 18%, respectively emulsification activity. This study reports two new diesel degrading bacterial species, which can be effectively used for bioremediation of petroleum contaminated sites.

在地质勘探的普查和详查工作中,土壤地球化学的指示作用是重要的决定性因素之一。随着地表及浅部矿产的开发,边深部盲矿体的找矿难度不断加大。按照目前的样品处理方法及技术要求,岩金矿区的矿化地段土壤测量分析数据被削弱,元素异常下限值偏低。为了解决异常贫化带来的异常圈定问题,本次研究对土壤样品的加工进行改进和调整。首次提出将野外采取的金矿土壤测量样细分,烘干处理后,不再进行过筛处理,并在湘东北醴陵市棉花坡金矿区的找矿普查工作中应用。对该区金矿土壤测量样品野外加工过筛与不过筛检测结果对比分析,未过筛样品能更客观、真实地反映矿区Au元素异常值情况,有利于指导找矿,取得了良好的找矿效果。因此,本次试验工作方法对指导类似金矿区土壤测量样品野外加工处理具有一定的借鉴意义。

儒家传播思想,是我国古代思想宝库中的一份非常重要的遗产,影响深远,衣被中华数千年。在人类迈向21世纪、世界各种文化相互冲突、融合的时候,探索儒家传播思想对东西方文化所产生的影响具有十分重要的意义。对儒家传播思想的考察,既要历史地回顾儒家传播思想对世界的影响,又要阐明儒家思想在当今以及未来的价值。揭示出儒家传播思想的产生发展的“传者本位”——“受众本位”——“回归的传者本位”否定之否定的逻辑过程。

Networked robots can perceive their surroundings, interact with each other or humans,and make decisions to accomplish specified tasks in remote/hazardous/complex environments. Satelliteunmanned aerial vehicle(UAV) networks can support such robots by providing on-demand communication services. However, under traditional open-loop communication paradigm, the network resources are usually divided into user-wise mostly-independent links,via ignoring the task-level dependency of robot collaboration. Thus, it is imperative to develop a new communication paradigm, taking into account the highlevel content and values behind, to facilitate multirobot operation. Inspired by Wiener’s Cybernetics theory, this article explores a closed-loop communication paradigm for the robot-oriented satellite-UAV network. This paradigm turns to handle group-wise structured links, so as to allocate resources in a taskoriented manner. It could also exploit the mobility of robots to liberate the network from full coverage,enabling new orchestration between network serving and positive mobility control of robots. Moreover,the integration of sensing, communications, computing and control would enlarge the benefit of this new paradigm. We present a case study for joint mobile edge computing(MEC) offloading and mobility control of robots, and finally outline potential challenges and open issues.

Few-shot text classification targets at the situation where a model is developed to classify newly incoming query instances after acquiring knowledge from a few support instances. In this paper, we investigate few-shot text classification under a metric-based meta-learning framework. While the representations of the query and support instances are the key to the classification, existing study handles them independently in the text encoding stage. To better describe the classification features, we propose to exploit their interaction with adapted bi-directional attention mechanism. Moreover, distinct from previous approaches that encode different classes individually, we leverage the underlying cross-class knowledge for classification. To this end,we conceive the learning target by incorporating the large margin loss, which is expected to shorten the intra-class distances while enlarging the inter-class distances. To validate the design, we conduct extensive experiments on three datasets, and the experimental results demonstrate that our solution outperforms its state-of-the-art competitors. Detailed analyses also reveal that the bi-directional attention and the cross-class knowledge both contribute to the overall performance.
