Nowadays, the consequences of failure and downtime of distributed systems have become more and more severe. As an obvious solution, these systems incorporate protection mechanisms to tolerate faults that could cause systems failures and system dependability must be validated to ensure that protection mechanisms have been implemented correctly and the system will provide the desired level of rel...

BACKGROUND Governments have endorsed global targets to reduce childhood undernutrition as part of the Sustainable Development Goals. Understanding the socioeconomic differences in childhood undernutrition has the potential to be helpful for targeting policy to reach these goals. METHODS We specify a logistic regression model with the Composite Index of Anthropometric Failure (CIAF) as the out...

Abstract The stability and lifetime of electrical contact pose a major challenge to the performance microelectro-mechanical systems (MEMS), such as MEMS switches. microscopic failure mechanism still remains largely unclear. Here conductive atomic force microscopy with hot switching mode was adopted simulate asperity-level condition in switch. Strong variation fluctuation current adhesion were o...
