Percolation transition is widely observed in networks ranging from biology to engineering. While much attention has been paid to network topologies, studies rarely focus on critical percolation phenomena driven by network dynamics. Using extensive real data, we study the critical percolation properties in city traffic dynamics. Our results suggest that two modes of different critical percolation behaviors are switching in the same network topology under different traffic dynamics. One mode of city traffic (during nonrush hours or days off) has similar critical percolation characteristics as small world networks, while the other mode (during rush hours on working days) tends to behave as a 2D lattice. This switching behavior can be understood by the fact that the high-speed urban roads during nonrush hours or days off (that are congested during rush hours) represent effective long-range connections, like in small world networks. Our results might be useful for understanding and improving traffic resilience. Copyright © 2017, The Authors. All rights reserved.

We present the calibration strategy for the 20 kton liquid scintillator central detector of the Jiangmen Underground Neutrino Observatory (JUNO). By utilizing a comprehensive multiple-source and multiple-positional calibration program, in combination with a novel dual calorimetry technique exploiting two independent photosensors and readout systems, we demonstrate that the JUNO central detector can achieve a better than 1% energy linearity and a 3% effective energy resolution, required by the neutrino mass ordering determination.

Despite the wide use of networks as a versatile tool for exploring complex social systems, little is known about how to detect and forecast abrupt changes in social systems. In this report, we develop an early warning approach based on network properties to detect such changes. By analysing three collaborative social networks-one co-stardom, one patent and one scientific collaborative network, we discover that abrupt transitions inherent in these networks can serve as a good early warning signal, indicating, respectively, the dissolution of the Soviet Union, the emergence of the "soft matter" research field, and the merging of two scientific communities. We then develop a clique growth model that explains the universal properties of these real networks and find that they belong to a new universality class, described by the Gumbel distribution.

Temperature-Dependent Drain Current Characteristics and Low Frequency Noises in Indium Zinc Oxide Thin Fihn Transistors

Chinese Physics Letters 2015年第8期32卷 208-211页

作者：刘远吴为敬强蕾王磊恩云飞李斌 Science and Technology on Reliability Physics and Application of Electronic Component Laboratory China Electronic Produce Reliability and Environmental Testing Research Institute Guangzhou 510610 State Key Laboratory of Luminescent Materials and Devices South China University of Technology Guangzhou 510640 School of Electronic and Information Engineering South China University of Technology Guangzhou 510640

The I-V characteristics and low frequency noises for indium zinc oxide thin film transistor are measured between 250 K and 430 K. The experimental results show that drain currents are thermally activated following the Meyer Neldel rule, which can be explained by the multiple-trapping process. Moreover, the field effect electron mobility firstly increases, and then decreases with the increase of temperature, while the threshold voltage decreases with increasing the temperature. The activation energy and the density of localized gap states are extracted. A noticeable increase in the density of localized states is observed at the higher temperatures.

IEEE Annual International Computer Software and Applications Conference (COMPSAC)

The Unified Modeling Language (UML) is rapidly emerging as a de-facto standard used for software specifications and UML sequence diagrams provide a visual technique to model and depict software behaviors. However, sequence diagrams cannot automatically analyze and verify software behaviors due to lack of strict semantics. To ensure the reliability of software systems, a behavior description and formal verification approach called formal sequence is proposed in this paper, which integrates extended UML sequence diagram and automata model. Firstly, sequence diagram is extended and formally defined into a two-dimensional diagram called SD2D. Then, a full-map relationship is established between SD2D and the timed automata network (TAN). Thirdly, on basis of the above mapping relationships, the model transformation approach is established, realizing the transformation from SD2D to TAN. Formal verification can be then carried out to check domain specific properties with automated model checkers like UPPAAL. Our proposed approach realizes a full-map from sequence diagram to TAN and bridges the gap between visual modeling and formal modeling of software. Experimental results show that the proposed approach of formal sequence is effective and efficient in behavior description and formal verification of software.

Sorptive Removal of Ce(IV) from Aqueous Solution by Bentonite

Procedia environmental sciences 2016年 31卷 408-417页

作者： Fengyu Huang Facheng Yi Zhe Wang Haifeng Li Key Subject Laboratory of National Defense for Radioactive Waste and Environmental Security Southwest University of Science and TechnologyMianyang 621010 PR China Institute of Engineering Surveying Sichuan College of Architectural Technology DeyangSichuan 618000 PR China

Bentonite has been studied extensively because of its strong adsorption capacity. A local bentonite named GMZ bentonite, collected from Gaomiaozi County (Inner Mongolia, China), was selected as the first choice of buffer/backfill material for the high-level radioactive waste repository in China. In this research, purification of raw bentonite was done to remove quartz. X-ray Diffraction(XRD) was used for the characterization of purified bentonite .In addition, the effects of contact time, solid dosage, pH, and temperature on Ce(IV) sorption to purified bentonite were also investigated by batch technique. The sorption kinetics and isotherms of bentonite for Ce(IV) indicate that the kinetic adsorption is well described by the pseudo-second-order model and the sorption isotherm is fitted well by Langmuir model. The equilibrium batch experiment data demonstrate that bentonite is effective adsorbent for the removal of Ce(IV) from aqueous solution.

In this paper, we focus on the need for ideal theory analytical solution of mechanical deformation mechanism for T-joints. Through removing unnecessary constraints, stress equivalence system of T-joints can be established by force method. Solution equations of unknown nodal forces and the total vertical displacement can also be obtained, and this result can be used to evaluate strength of FRC T-joints.
