Towards continuous EIT monitoring for hemorrhagic stroke patients

open access: yesFrontiers in Physiology, 2023
The practical implementation of continuous monitoring of stroke patients by Electrical Impedance Tomography (EIT) is addressed. In a previous paper, we have demonstrated EIT sensitivity to cerebral hemodynamics, using scalp-mounted electrodes, very low ...

Multi-Frequency Band Pyroelectric Sensors [PDF]

open access: yesSensors, 2014
A methodology is proposed for designing a multi-frequency band pyroelectric sensor which can detect subjects with various frequencies or velocities. A structure with dual pyroelectric layers, consisting of a thinner sputtered ZnO layer and a thicker aerosol ZnO layer, proved helpful in the development of the proposed sensor.

Multi-Frequency VLBI observations of 3C390.3 [PDF]

open access: yesSymposium - International Astronomical Union, 1996
We have mapped the broad line radio galaxy 3C390.3 at 1.3, 6, and 18 cm wavelengths with resolutions ranging from 0.2 to 2.7 mas. Our new 6 cm image is consistent with a stationary bright region located 4 to 5 mas from the core and motion of the other features with apparent velocities of 0.4 to 0.7 mas/yr.
