From the amplitude analysis of $D^+_s \to \pi^+ \pi^0 \eta$ decay, BESIII Collaboration firstly observed a_0(980)^+\pi^0$ and a_0(980)^0\pi^+$ decay modes, which are expected to occur through pure $W$-annihilation processes. The measured branching fraction $\mathcal{B}[D_{s}^{+}\to a_{0}(980)^{+(0)}\pi^{0(+)},a_{0}(980)^{+(0)}\to \pi^{+(0)}\eta]$ is, however, found be larger than those known de...

An exfoliative toxin produced by Staphylococcus aureus is the causative agent of staphylococcal scalded-skin syndrome (SSSS) in young children. Recently, we reported that only few isolates of S. aureus from bovine mastitis contained the eta gene encoding exfoliative toxin A (ETA) and produced ETA in vitro. In this study, we isolated temperate phages from two ETA-positive bovine isolates of S. a...

The paper illustrates how event tree diagrams, used in safety engineering, can be applied to test the design of a healthcare service. Event tree diagrams can be employed to inform quantitative approaches to quality, by providing justification with respect to safety, of operational aspects to be monitored and measured.

Currently, from the statistical analysis of accidents at home and abroad, the number of automobile defects and the resulting automobile accidents are very large. Obviously, the automobile defects have become one of the main factors affecting traffic safety, and risk assessment as an automobile key technical defect of risk management, the elimination of defects and reduce automobile accidents ar...

The RAVEN code has been under development at the Idaho National Laboratory since 2012. Its main goal is to create a multi-purpose platform for the deploying of all the capabilities needed for Probabilistic Risk Assessment, uncertainty quantification and data mining analysis. RAVEN is currently equipped with three different sampling strategies: Once-through samplers (Monte Carlo, Latin Hyper Cub...
