In this study, the Ag/Ag Cl/WO3 plasmonic Z-scheme photocatalysts with different contents of Ag/Ag Cl nanoparticles（NPs） were prepared through a facile ultrasonic precipitation method in geothermal water,wherein the geothermal water served as the chlorine source. Then the photocatalytic activity was investigated by degradation of 4-Aminobenzoic acid（4-ABA） under visible-light irradiation. It was found that the as-prepared 50 wt% Ag/Ag Cl/WO3 photocatalyst showed the highest photocatalytic efficiency with 25.12 and 3.53 times higher than those of pure WO3 and Ag/Ag Cl, respectively. The active species trapping experiments indicated that h＋and ·O2-were key factors in 4-ABA photodegradation process. The possible plasmonic Z-scheme photocatalytic mechanism of photocatalytic reaction for 4-ABA degradation was proposed based on systematical characterizations. We hope this paper could give new ideas for further exploiting geothermal energy to design and fabricate highly efficient visible-light-driven photocatalysts for environmental remediation.

Simultaneously adjusting the surface,crystallographic and electronic structures of nanomaterials provide a new avenue for rational design of advanced photocatalyst yet it is challenging.In this work,a surface and structural engineering strategy is developed to simultaneously realize the 2D amorphous structure and oxygen(O)-doping in graphitic carbon nitride(g–C_(3)N_(4))via the assistance of supercritical carbon dioxide(SCCO_(2)).The 2D O-doped amorphous g-C_(3)N_(4)nanosheets display greatly enhanced photocatalytic CO_(2)reduction and methylene blue degradation performances.The synthesis method as well as the mechanism of the enhanced photocatalytic activity was investigated,wherein the introduction of 2D amorphous structure and O dopant in the g-C_(3)N_(4)contributes to the increased surface area,abundant active sites,wider visible-light absorption range and efficient charge separation property,and thus the outstanding photocatalytic activities can be obtained.Its photocatalytic CH_(4)evolution rate and MB degradation rete are 5.1 and 7.0 times enhancement over bulk crystalline g-C_(3)N_(4),respectively.This work presents a great promising way for designing and developing advanced photocatalysts.

The local water resources of Shandong peninsula blue economic zone are shortage, and the the annual water resources change greatly and are uneven in distribution, development and utilization is very difficult. From the local water resources characteristics, current situation water supply project and water shortages analysis, this area generally belongs to resource-based water shortage, engineering type water shortage and water quality type shortage coexistence in the region. So, the study of the preliminary research of water resources guarantee ability in Shandong peninsula blue economic zone is very important. Using fuzzy mathematical model and research shows that, in the implementation of all kinds of water resources guarantee engineering conditions, the regional water resources comprehensive support capacity showsa rising trend, the year of 2008 is a possible guarantee, the year of 2015 is a basic security, the year of 2020 is a fully protection;points out the restriction of Shandong peninsula blue economic zone of the main bottleneck water resources guarantee ability, puts forward the key construction projects and the countermeasures and suggestions to improve its ability of water resources guarantee.

With the advent of the 5G era and the accelerated development of edge computing and Internet of Things technologies, the number of tasks to beprocessed by mobile devices continues to increase. Edge nodes become incapable of facing massive tasks due to their own limited computing capabilities, and thus the cloud and edge collaborative environment is produced. In order to complete as many tasks as possible while meeting the deadline constraints, we consider the task scheduling problem in the cloud-edge and edge-edgecollaboration scenarios. As the number of tasks on edge nodes increases, the solution space becomes larger. Considering that each edge node has its own communication range, we design an edge node based clustering algorithm (ENCA),which can reduce the feasible region while dividing the edge node set. Subsequently, we transform the edge nodes inside the cluster into a bipartite graph, and thenpropose a task scheduling algorithm based on maximum matching (SAMM). Finally, our ENCA and SAMM are used to solve the task scheduling problem. Compared with the other benchmark algorithms, experimentalresults show that our algorithms increase the number of tasks which can be completed and that meet the latest deadline constraints by 32%-47.2%under high load conditions.

数字广告流量造假,指在广告主与数字广告媒介组织以契约为规则的交易中后者采取的一种机会主义行为,危害极大。目前“否定逻辑”契约条款治理流量造假已经陷入困境,而区块链智能合约BAT平台则能够有效治理流量造假。本文对BAT平台应用展开的案例研究发现,其“肯定逻辑”契约条款在实践中形成了不同于“否定逻辑”契约条款的全新治理模式:不仅治理主体及对象不同,而且治理手段、机理及结果亦不同,即创新了流量造假的治理方法论。

Pulsar navigation technology is an important technology in the construction of national integrated positioning and navigation timing（PNT）system. It can provide high-precision autonomous navigation service and high stable time-frequency reference. High precision pulsar signal propagation model is the prerequisite for realizing high-precision navigation and high stability pulsar time. In view of the inconsistency of existing pulsar observation models and the need to expand the application scope of pulsar navigation and time service to deep space, under the framework of general relativity, through the geometric The gravitational delay formula of pulsar signal under the second-order post Newton effect in the solar system is analyzed and deduced,and a universal pulsar observation model in the solar system is established.According to the influence magnitude of various time delays, a simplified observation model in near earth space with accuracy better than 1 ns is obtained..

近年来,新辅助化疗越来越多地应用到局部晚期和早期乳腺癌患者的治疗中,且在一定程度上改善了疾病的病理状态和分期,这使乳腺癌患者新辅助化疗后术后放疗的决策更为复杂。现有指南已指出新辅助化疗后腋窝淋巴结阳性的患者推荐行术后放疗。但是在新辅助化疗后达病理完全缓解或腋窝淋巴结转阴的患者中术后放疗尚存在争议。放疗可以提高患者的局部控制率和总生存率,但是部分患者接受放疗后会出现一系列的不良反应。因此,寻找在新辅助化疗后能从术后放疗中获益的患者显得十分重要。文章就新辅助化疗后达病理完全缓解或腋窝淋巴结转阴乳腺癌患者行术后放疗的研究进展进行综述。
