Summary: The System of Cyber-Physical Systems (SoCPS) consists of multiple independent Cyber-Physical Systems (CPSs) that collaborate to achieve a common mission. However, the complexity and safety-critical nature of SoCPS require a proper safety analysis mechanism. This paper introduces a composite safety analysis approach called SafeSoCPS, which analyzes potential hazards for the whole network of CPS and traces faults among the participating systems using a fault propagation graph. The results show that the SafeSoCPS approach can identify more faults in a network of SoCPS.

Summary: In this article, a resilience evaluation method for cyber-physical power systems (CPPS) considering the entire process of cyber attacks is proposed. This method includes a calculation model for successful attack probability, a mixed sampling method to determine fault occurrence and repair time, and an optimal load reduction model based on the DC power flow. Four evaluation indices for attack risk resistance, system adaptability, repair rate, and comprehensive weighted index are also proposed. A case study based on the IEEE RTS 79 system is conducted to verify the effectiveness of this method.

Summary: This paper studies the impact of quality sorting standards and classification errors on the decision-making and performance of supply chains. The results show that a higher quality sorting standard is not always beneficial for enterprises, and classification errors have opposite impacts on the profits of different recycling channels. Enterprises can optimize their performance by controlling error proportions and combining with their own sorting modes. Additionally, a third-party recycler participating in the recycling competition can optimize the manufacturer's profits and supply chain performance without harming the manufacturer's profits.

Summary: The numerical design of the TiNbTaZrMoSn alloy was conducted before its manufacture to predict its performance, and the experimental results were found to be in good agreement with the predictions. The study highlighted the importance of oxide layer thickness and surface potential in osteogenic activity, while cell adhesion and viability were less affected. The TiNbTaZrMoSn alloy showed slightly lower osteogenic properties compared to c.p. Titanium due to its thinner oxide layer and lower surface potential.
