Infrared light from the imaging laser was blocked with a filter located in front of the camera.
Since each g k (n) is a band-passed filter located at a separate part of frequency domain, it can be considered as a subcarrier waveform.
They captured the delivered aerosol (generated by MDI and delivered into a VHC) on filters located at the tracheal port of an infant airway model, the Sophia Anatomical Infant Nose-Throat model.
These lasers then sweep by employing a tunable filter, located inside the cavity, that creates large loss at all but a small subset of these modes.
A narrow band interference filter located in a collimated beam allows isolating the Lyman-α line.
Bypass or filtered air was then directed through a high efficiency particulate air (HEPA) filter located before the high volume sampling pump.
The other filter is on the hose which supplies the clean water; this filter is located at the back of the machine near the squeegee assembly.
To address paradoxical effects of anti- calmodulin agents, we hypothesized that these compounds might not enter the cell, but inhibit the pore opening of pain/TRPV1 channel, most likely directly at the cation filter site, located at the extra-cellular orifice of the Ca2+-channel.
Center modulation frequencies of the chosen five amplitude modulation filters are located at 0, 5, 10, 16.67, and 27.78 Hz, respectively, i.e., cover a much wider modulation frequency range compared to D and DD features that are located around 10 Hz.
As baseband filter, a simple AR(1) spectrum is used, with a peak located at zero frequency, i.e., one pole in ρ.
All channels were recorded against a reference electrode located at FCz. EEG and EOG were analogue filtered (0.1-100 Hz) and recorded with a sampling rate of 500 Hz.
