The recurrent activity of radio AGN, with phases of activity alternating with periods of quiescence, has been known since the early studies of these objects.The full relevance of this cycle is emphasised by the requirement, from the AGN feedback scenario, of a recurrent impact of the energy released by the SMBH during the lifetime of the host galax
Summary: An evolving family of mobile colistin resistance (MCR) enzymes is threatening public health.However, the molecular mechanism by which the MCR enzyme as a rare member of lipid A-phosphoethanolamine (PEA) transferases gains the ability to confer phenotypic colistin resistance remains enigmatic.Here, Knitwear we report an unusual example that
Autonomous systems are these systems which power themselves from the available ambient energies in addition to their duties.In the next few years, autonomous systems will pervade society and they will find their ways into different applications related to health, security, comfort and entertainment.Piezoelectric harvesters are possible energy conve
