A Systemic Review of Available Low-Cost EEG Headsets Used for Drowsiness Detection.
TL;DR: A systemic review of currently available, low-cost, consumer EEG-based drowsiness detection systems found that even basic features, such as the power spectra of EEG bands, were able to consistently detect drowsness.
Temperature-dependent thermal properties of ex vivo liver undergoing thermal ablation
Sitaramanjaneya Reddy Guntur,Kang Il Lee,Dong-Guk Paeng,Andrew Coleman,Min Joo Choi,Min Joo Choi +5 more
TL;DR: The study indicates that the key thermal parameters of ex vivo porcine liver vary largely with temperature when heated, as described by asymmetric quasi-parabolic curves of the thermal parameters with temperature, and therefore, substantial influence on the temperature distribution of the tissue undergoing thermotherapy is expected.

Doppler power variation from porcine blood under steady and pulsatile flow
TL;DR: It was found that the Doppler power from porcine whole blood under steady flow decreased with the speed by approximately 13 dB and was only 3 dB higher than that from RBC suspension at 33 cm/s, suggesting minimal RBC aggregation in whole blood at this speed.

Improvement of ultrasound speckle image velocimetry using image enhancement techniques
TL;DR: The image-enhancement techniques used in this study can minimize errors encountered in ultrasound SIV measurement in which RBCs are used as flow tracers instead of exogenous contrast agents.

The “black hole” phenomenon in ultrasonic backscattering measurement under pulsatile flow with porcine whole blood in a rigid tube
TL;DR: The "black hole" phenomenon was further investigated with porcine whole blood under pulsatile flow conditions in a straight rigid tube and showed that the black hole was more pronounced at higher beat rates when the peak velocity was the same.
