Pulsed FUS exposure was delivered to induce BBB opening (500-kHz, burst length = 10 ms, 1% duty cycle, PRF = 1 Hz).
The intensity of the magnetic stimulation was 60%, with a frequency of 20Hz, and a burst length of 2 seconds for the gastric emptying protocol.
If the traffic were Markovian process, the traffic's burst length would be smoothed by averaging over a long time scale contradicting with the observations of today's traffic characteristics.
The burst length was then defined as a time subinterval where the band average instantaneous power was higher than half of the local maximum (half-power point) estimated using the Gaussian fit.
The frequency coordinate of the peak of the Gaussian fit was recognized as the central burst frequency and the burst's frequency width was defined analogously to the burst length but in the frequency domain.
Using a combination of these techniques for the connected digits task, word accuracy is increased from 49.5% to 95.3% even with a packet loss rate of 50% and average burst length of 20 feature vectors.
A fast frequency drift in burst-mode operation is inherent to directly modulated lasers, but depends on the specific laser design, the laser output power and the burst length.
Specifically, we consider pre-recorded CM applications and use the following metrics in evaluating the performance of multi-path streaming as compared to single-path streaming: (a) data loss rate, (b) conditional error burst length distribution, and (c) lag1-autocorrelation.
The right hippocampus (see Supplementary Fig. S1) was then exposed to burst-mode ultrasound (acoustic pressure = 0, 0.51, 0.5 MPa for group 1 and 0.41 MPa for group 2; burst length = 10 ms; pulse repetition frequency = 1 Hz; exposure time = 60 s).

(b) Mean normalized difference of CRLBs vs. burst length K ′.
