Testing was at constant amplitude in artificial seawater at 5°C using a frequency of 0.2 Hz.
Optimum conditions were obtained in the 8 Vp − p using a frequency of 10 Hz of a sinusoidal waveform.
Briefly, grain (about 0.5 g) was homogenized in 5 mL of 60% ethanol, treated for 4 hours in a oscillations instrument (HZS-H, China) using a frequency of 200 oscillations per minute.
The designed and simulated prototype CAHM used a frequency of 2.25 MHz and measured sound speed changes of 16 m/s, temperature changes of 5 °C and had a spatial resolution of 660 μm.
In this paradigm we used a frequency of stimulation determined during the ON period, to be used at the end of dose time epoch.
Our objective is to determine the impact of auditory stimulation on FOG when the effect of the medication has decayed, but importantly using a frequency of stimulation normalised as a function of gait pattern of each patient.
However, it is important to know the time scales of the different processes observed in order to use a frequency of measurement that will not miss important changes of the system.
In children weighing <10 kg we used a frequency of 10 Hz, in children weighing >10 kg we used a frequency of 8 Hz.
Both power Doppler machines used a frequency of 12 MHz, 0.5 PRF (pulse repetition frequency).
We used a frequency of 90%% as a cut-off for SNV calling.
