In the summer of 2003, a heat wave swept Europe and caused more than 70 000 additional fatalities [J.-*** et al., C. R. Biologies 331 (2008)]. Global warming and climate change is no longer a prophecy to be fulfilled, as strong heat waves and typhoons, as well as severe rainfalls, are becoming more severe. Extreme weather and climate events in the world, especially over Europe and North America, are widely studied and frequently

China Central Television broadcasted live reports on the latest archaeological excavation at the Sanxingdui site over four consecutive days,from 20–23 March 2021. Exquisite large golden mask fragments, as well as numerous bronze, jade, pottery and ivory artefacts, were unearthed in six newly discovered pits at the site. Following the public presentation of these ancient cultural relics, along with the contemporary archaeological excavation technologies, the mysterious Sanxingdui civilization has become a hot topic within the Chinese media and scientific community.

A practical approach for predicting the congestion boundary due to traffic incidents was proposed. based on the kinematic wave theory and Van Aerde single-regime flow model, a model for estimating the congestion propagation speed for the basic road segment was developed. Historical traffic flow data were used to analyze the time variant characteristics of the urban traffic flow for each road type. Then, the saturation flow rate was used for analyzing the impact of the traffic incident on the traversing traffic flow at the congestion area. The base congestion propagation speed for each road type was calculated based on field data, which were provided by the remote traffic microwave sensors(RTMS), floating car data(FCD) system and screen line survey. According to a comparative analysis of the congestion propagation speed, it is found that the expressway, major arterial, minor arterial and collector are decreasingly influenced by the traffic incident. Subsequently, the impact of turning movements at intersections on the congestion propagation was considered. The turning ratio was adopted to represent the impact of turning movements, and afterward the corresponding propagation pattern at intersections was analyzed. Finally, an implementation system was designed on a geographic information system(GIS) platform to display the characteristics of the congestion propagation over the network. The validation results show that the proposed approach is able to capture the congestion propagation properties in the actual road network.

A few years ago, after a vehement round of inner city renewal, I suddenly found many sidewalks in the city proper of beijing became so narrow that pedestrians often had to compete with bikes and even automobiles for a space to walk. The place where we used to enjoy strolling were given way either to bike lanes or to thoroughfares, or taken for the parking of automobiles that are ever increasing in the city.

Dear editor,This letter studies output consensus problem of heterogeneous linear multiagent systems over directed graphs. A novel adaptive dynamic event-triggered controller is presented based only on the feedback combination of the agent's own state and neighbors' output,which can achieve exponential output consensus through intermittent communication. The controller is obtained by solving two linear matrix equations, and Zeno behavior is excluded.
