Mutualism promotes site selection in a large marine planktivore
Ecology and Evolution, 2021 Mutualism is a form of symbiosis whereby both parties benefit from the relationship. An example is cleaning symbiosis, which has been observed in terrestrial and marine environments.

High-Accuracy Reference-Free Ultrasonic Location Estimation [PDF]
IEEE Transactions on Instrumentation and Measurement, 2012 This paper presents a novel reference-free ultrasonic indoor location system. Unlike most previous proposals, the mobile device (MD) determines its own position based only on ultrasonic signals received at a compact sensor array and sent by a fixed independent beacon. No radio frequency or wired timing reference signal is used.
