Subway emergency may lead to passengers' panic, especially under self-organizing circumstance, which will spread rapidly and have an adverse impact on the society. This paper builds an improved SIRS model of passengers' panic spread in subway emergency with consideration of passengers' density, the characteristic of subway car with the confined space, and passengers' psychological factors. The spread of passengers' panic is simulated by use of Matlab, which draws the rules of how group panic spreads dynamically. The trend of stable point of the infection ratio is analyzed by changing different parameters, which help to draw a conclusion that immunization rate, spontaneous immune loss rate, and passenger number have a great influence on the final infected ratio. Finally, we propose an integrated control strategy and find the peak of passengers' panic and the final infected ratio is greatly improved through the numerical simulation. The research plays a vital role in helping the government and subway administration to master the panic spread mechanism and reduce the panic spread by improving measures and also provides certain reference significance for rail system construction, emergency contingency plans, and the construction and implementation of emergency response system.

Cooperation of all the members in a supply chain plays an important role in logistics service. The service integrator can encourage cooperation from service suppliers by sharing their cost during the service, which we assume can increase the sales by accumulating the reputation of the supply chain. A differential game model is established with the logistics service supply chain that consists of one service integrator and one supplier. And we derive the optimal solutions of the Nash equilibrium without cost sharing contract and the Stackelberg equilibrium with the integrator as the leader who partially shares the cost of the efforts of the supplier. The results make the benefits of the cost sharing contract in increasing the profits of both players as well as the whole supply chain explicit, which means that the cost sharing contract is an effective coordination mechanism in the long-term relationship of the members in a logistics service supply chain.

The paper presents a human-machine design approach to the artistic and metaphoric representation of the traditional weaving scene of Yunjin brocade as interactive Moiré patterns accompanied by Nanjing Baiju. We extract the basic elements of Moiré patterns and systematically recompose them to mimic the weaving process. Then, we wrote an algorithm to generate eye-shaped Moiré patterns responding dynamically to the unique sounds weavers make while weaving, symbolizing the long and tiring gaze of warp and weft, and eye contacts between weavers. Finally, we develop a sonic interactive installation with the rhythmic machine sound and Nanjing Baiju Sweating Weaving Room, visualizing the hard labor and harmonious work hidden behind the glamourous brocade.
