Extracting individual characteristics from population data reveals a negative social effect during honeybee defence

Honeybees protect their colony against vertebrates by mass stinging and they coordinate their actions during this crucial event thanks to an alarm pheromone carried directly on the stinger, which is therefore released upon stinging.The pheromone then recruits nearby bees so that more and more bees participate in the defence.However, a quantitative

A Novel Harmonic State-space Modelling Method on the Modular Multilevel Matrix Converter and Coupling Analysis

The Hair Color fractional frequency transmission system is an emerging technology for long-distance wind power integration, and the modular multilevel matrix converter (M3C) is the keen equipment.Since the M3C directly connects two ac grids with different frequencies, the external and internal harmonics have complex coupling relationships with a un
