Computational fluid dynamics simulations of airflow through the nasal passages of rhinolophoid bats

The Anatomical Record, EarlyView.
Abstract The nasal passages of bats that emit their echolocation call through their nostrils have adapted for sound emission as well as standard respiratory and olfactory functions. Rhinolophids, hipposiderids and rhinonycterids all use a high duty cycle (HDC) echolocation strategy.

Color Doppler Twinkling Artifact and Clinical Use

Journal of Medical Ultrasound, 2009
The color Doppler twinkling artifact manifests as a rapidly changing mixture of red and blue colors behind a strongly reflecting structure. Spectral Doppler analysis of the twinkling artifact does not yield a flow spectrum. It is important to recognize this artifact because it may lead to misdiagnosis of vascular flow within a tissue. Additionally, the
