Bacground and objective: Assessing the threats and vulnerabilities of infrastructure is one of the major concerns of security officials in a country, and water supply systems are one of the most important and sensitive infrastructures. Water supply systems are also among the basic infrastructures that are very important in assessing the threats in these systems and identifying its weaknesses. I...

Environmental concerns and depletion of nonrenewable resources has made great interest towards renewable energy resources. Cleanness and high potential are factors that caused fast growth of wind energy. However, the stochastic nature of wind energy makes the presence of energy storage systems (ESS) in wind integrated power systems, inevitable. Due to capability of being used in large-scale sys...

Centriolar satellites (CS) are small granular structures that cluster in the vicinity of centrosomes. CS are highly susceptible to stress stimuli, triggering abrupt displacement of key CS factors. Here we discover a linear p38-MK2-14-3-3 signalling pathway that specifically targets CEP131 to trigger CS remodelling after cell stress. We identify CEP131 as a substrate of the p38 effector kinase M...
