In typical sensor networks, data collection and processing are separated. A sink collects from all nodes sequentially, which is very time consuming. Over-the-air computation, as a new diagram of integrates in one slot: transmit their signals simultaneously the analog wave done air. This method, although efficient, requires that arrive at sink, aligned signal magnitude so to enable an unbiased e...

Macroclimate warming is affecting ecosystems world-wide. Tree canopies, however, can significantly buffer temperature fluctuations, giving rise to lower maximum temperatures, higher minimum temperatures and enhanced water availability at the forest floor. Forests, therefore, act as refugia for heat-sensitive species with important implications climate-change responses in understorey of forests....
