Humans quickly and accurately learn new visual concepts from sparse data, sometimes just a single example.The impressive performance of artificial neural networks which hierarchically pool afferents across scales and positions suggests that the hierarchical organization of the human visual system is critical to its accuracy.These approaches, howeve
Brood parasitism frequently leads to a total loss of host fitness, which selects for the evolution of defensive traits in host species.Experimental studies have demonstrated that recognition and rejection of the parasite egg is the most common and efficient defence used by host species.Egg-recognition experiments have advanced our knowledge of the
During embryogenesis motor axons navigate MR16 LED to their target muscles, where individual motor axons develop complex branch morphologies.The mechanisms that control axonal branching morphogenesis have been studied intensively, yet it still remains unclear when branches begin to form or how branch locations are determined.Live cell imaging of in
Systems engineering of a satellite based data communication baseline concept is presented to achieve terabit per second throughput.It uses a constellation of five Molniya satellites and one dimension electronic scanning phased array ground terminals.The result is a baseline concept that meets customer needs for internet of things (IoT) data connect
