Within the past few years, members of the hedgehog (hh) family of secreted signalling proteins have emerged as the primary signals generated by certain embryonic patterning centres.
The divers are equipped with a hydrophone to detect acoustic signals generated by seismic waves.
Signals generated by the dialer activate switches in the local office, which establish a transmission path to the called party.
We derive the statistics of the signals generated by shape fluctuations of large molecules studied by feedback tracking microscopy.
The electronic control signals generated by UHCI from the calculated head position mimic those produced by a joystick.
First, statistical features of the residual signals generated by means of an observer are studied.
These devices, strapped to the chest, sense the electrical signals generated by the nervous system in controlling the beating of the heart.
Scientists have long speculated that what feel like physical limits are often merely warning signals generated by the brain's protective circuitry.
Third, electrical signals generated by muscular activity such as blinking are easily confused with actual brain-wave readings.
More complex instruments include the familiar X-ray machines and electroencephalographs and electrocardiographs, which detect electrical signals generated by the brain and heart, respectively.
The ever-widening communications system creates a vast number of digital signals generated by consumer interactions on their smartphones, tablets and desktops.
