A portable acoustic micro-Doppler radar system for the acquisition of human gait signatures in indoor and outdoor environments is reported. Signals from an accelerometer attached to the leg support the identification of the components in the measured micro-Doppler signature. The acoustic micro-Doppler system described in this paper is simpler and offers advantages over the widely used electromagnetic wave micro-Doppler radars.

Article Synopsis
  • The rising misuse of drones by civilians, in addition to their military use, poses significant concerns that need attention.
  • Researchers investigated the effectiveness of micro-Doppler analysis from a drone's rotating blades in a specialized Forward Scattering Radar (FSR) setup, which offers advantages over traditional radar methods.
  • The study demonstrated successful detection of a drone using the FSR system, validating the concept and highlighting the potential for using a parabolic dish antenna to further enhance radar performance in the future.

Objective: Zebrafish has been recently considered an ideal vertebrate for studying developmental biology, genetics, particularly for modeling tumorigenesis, angiogenesis, and regeneration in vivo. However, when a zebrafish matures completely, its body loses transparency, thus making conventional optical imaging techniques difficult for imaging internal anatomy and vasculature. Acoustic wave penetration outperforms optical methods, high-frequency (>30 MHz) ultrasound (HFUS) was consequently an alternative imaging modality for adult zebrafish imaging, particularly for echocardiography However, visualizing peripheral vessels in a zebrafish by using conventional HFUS is still difficult.

Background: Recent reports have validated the use of retrosigmoid approach extensions to deal with petroclival lesions.

Objective: To describe the topographic retrosigmoid anatomy of the intrapetrous internal carotid artery (IICA), providing guidelines for maximizing the petroclival region exposure via this route.

Methods: The IICA was exposed bilaterally in 6 specimens via a retrosigmoid approach in the semisitting position.
