By enabling the observation of cilia beating frequency, the experimental model described in this work provides more realism for clinical applications.

It turned out 90 Hz is near the same frequency as wing beats of parasitic wasps, the jumping spider's biggest enemies, which provision their nests with jumping spiders for their young to feed on.

For the light pulses, the beats have the same frequency as the comb's offset frequency because every doubled low - end line will be mistuned by that amount from a high - end line.

While flow cues created by tail - beat frequency proved to be a critical trigger for shoaling behavior, coloration proved slightly dominant.

«Even at tail - beat frequencies that were less than optimal for the live fish, the shiners were always more drawn to the naturally colored robot,» Porfiri added.

The results indicate that, obtained with a tail - beat frequency of, is a critical speed for the robotic fish, with increases above or below this threshold differentially affecting zebrafish collective response.

To control for the effects of the tail beating and the visual cues from the robot, additional tests are performed in which the robot is beating its tail at a constant frequency in a fixed position in the tank or is completely absent.

In other words, for a tail - beat frequency matching the spontaneous tail - beat frequency of live fish, the naturally colored robotic fish was more attractive than the red replica.

In addition, PIV analyses were performed for all the tail - beat frequencies used in the behavioral study in each of the focal compartments.

For tail - beat frequencies of 2 Hz and 4 Hz, the time intervals between the generation of the vortices was lapse or compact, respectively, confirming that the shape and distribution of vortical structures in the robot's wake is controlled by its undulations.

The final value for the tail - beat frequency of live fish was calculated as the average of the six distinct main frequencies.

Specifically, the following predictions are expected to be met: i) fish attraction toward the robotic fish should vary as the visual cues offered by the robotic fish are varied, in agreement with similar observations for zebrafish in [35]--[37]; ii) fish attraction should vary as a function of the robotic fish tail - beat frequency, as suggested in [60] and observed in [20]; and iii) the highest attraction should be reached when both visual and flow cues from the live fish are simultaneously integrated in the robotic fish prototype.

The time spent in the non-focal region of the test tank complemented the time spent in the focal region, that is, the mean time spent within the non-focal region was the lowest for a tail - beat frequency of 3 Hz (114.2 s).

The tail - beat frequency was calculated for the six live fish by averaging the data from three distinct ten second long videos.

Similarly to the analysis for the top compartment, the time spent by fish in the bottom compartment was not affected by the tail - beat frequency of the robot, see Figure 7.

The time spent by fish in the middle compartment (49.2 s) was the highest when the robot tail - beat frequency was set at 2 Hz and post-hoc comparisons revealed that such time was significantly different than the time spent in the middle compartment for the robot beating its tail at 4 Hz (35.2 s), see Figure 7.

The time spent in compartment B3 (28.5 s) was the highest when the robot tail - beat frequency was set to 3 Hz, and post-hoc comparisons revealed that such time was significantly different than the time spent in B3 for the robot beating its tail at 0 Hz or 2 Hz (24.5 s or 24.6 s, respectively), see Figure 7.

The very very last thing that I add in and sometimes it can be a good 12 - 15 weeks before I add in this component is chronic competitive motion where it's okay, we're actually going out to go on a bike ride or swim or run or something that is metabolic conditioning roadwork because that's the stuff in someone that is overtrained who often times has their parasympathetic nervous system really really beat up you know, if you test their heart rate variability, the number called there high frequency is really really consistently low you know usually because there are triathletes or marathoners that's more often I'm dealing with those people with adrenal fatigue than I am with like a cross fitter who's kind of an opposite sympathetic nervous system fatigue issue but with those parasympathetic nervous fatigue, the last thing we add back in is the swimming and the biking and the running because it's important to realize that when you're trying to recover from adrenal fatigue or overtraining, even if you're doing like an easy swim or an easy bike ride or an easy run, if you're a triathlete or a marathoner or a swimmer or a cyclist, those easy sessions send a message to your body that you're training, that you're running from a lion and you still get that hormonal depletion and it's so easy for you to just turn into a depletion session and so that's the very very last thing that I'll add back in so that's kinda like the crow's eye view of you know, the type of things that I'll implement in a program for overtraining recovery, you know and you know, this is something that people hire me to walk them through.

Taking away the instruments, the multiplayer and the focus on achieving professional musicianship that the series previously strove for, Blitz brings things back to the old days of Frequency where it was just you tapping a couple of simple buttons to the beat.
