ObjectiveTo study the epidemiological characteristics of deaths due to pneumoconiosis and its complications in order to improve the prevention and management of pneumoconiosis.MethodsThe pneumoconiosis deaths who died during 1959‒2019 in Chongming District of Shanghai were investigated and analyzed retrospectively by the descriptive epidemiological methods. The correlation of the age of onset and the course of disease was analyzed by Spearman rank correlation，as well as the duration of dust exposure and the course of disease in pneumoconiosis patients.ResultsFrom 1959 to 2019， there were 226 pneumoconiosis deaths， 223 males （98.67%）. The mortality of silicosis was the highest （82.07%）. The age of onset of pneumoconiosis was negatively correlated with the course of disease （rs=-0.596，P

To reduce the risk of vehicle instability caused by driver fatigues, a shared differential steering control method considering fatigue characteristics of the driver was proposed. First, a driver-vehicle model for describing the characteristics of driving fatigues was established. Then, a dynamic output feedback robust controller was designed considering the uncertainties of vehicle speed, neuromuscular stiffness and delay time. Besides, the pole configuration method was adopted to improve the stability of the driver-vehicle closed-loop system. Finally, the combination of PreScan\Carsim\Simulink platform and the driver-in-the-loop test platform were set up. Experimental results show that with the assistance of the shared steering control method, the path tracking error index under different fatigue states is reduced by more than 59. 53%, improving the path tracking performance of the vehicle. For mild and severely fatigued drivers, the indices of the physiological load and the psychological load are both reduced by more than 48. 92% with the assistance of the controller. Thus, different levels of personalized assisted driving are realized. [ABSTRACT FROM AUTHOR]

To evaluate an ultra-lightweight blockcipher Piccolo's ability to counteract Power Analysis Attack (PAA), an attack model, which focuses on the first round of Piccolo, was proposed and Correlation Power Analysis (CPA) was conducted on this cipher based on a power simulation acquisition platform. Due to the whiten keys and round permutation for the first round of Piccolo, attacking keys including RK0L, RK0R, WK0 and WK1 were divided into six sub-keys, which were disclosed one by one. This approach can reduce the 80 - bit primary key search space from 280 to (2×220+2×24+2×28+216) and make it possible to recover the primary key. The attack results show that 500 power traces are enough to recover Piccolo's 80 - bit primary key. It is concluded that the hardware implementation of Piccolo without any countermeasure is vulnerable to CPA and some countermeasures should be used. This work is the first known report about the security of Piccolo against PAA. [ABSTRACT FROM AUTHOR]

Two active suspension controllers are designed respectively for improving ride comfort and handling stability, and an extended framework for integrated chassis control is built based on multi-agent architecture to make active suspension controllers work concertedly with integrated chassis control system covering active steering and active drive/brake torque distribution. The performance of the framework under critical manipulation condition is then simulated with Matlab/Simulink. The results show that the local controller as an agent can handily be incorporated into integrated control system, embodying the extendibility of multi-agent-based integrated chassis control framework, which can enhance both handling stability and ride comfort of vehicle simultaneously.
