# No rush--but: Would any of you help me understand these difficult equations (in link)?

So this question was posed and I was curious as to the correct answer. There is no rush--I am merely curious and would especially like to understand the equations in the link provided if any of you would be so kind as to explain some basics to me :3
If anyone could provide me with the correct answer to the question in the first picture, I will give you one whole cookie

Extra source (incl. the equations)

this gave me a headache, I'm sorry I can't help beyond that feedback lol

It's okay! We know the answer: Essentially the RRI in figure one emulates the increase reflected on the second figure at the RR spectral peak. As the for the second part of the answer, my fiance seems to know--but I am a bit lost. I literally took this class last semester and already these kids are learning new things! I'm just trying to keep on the up-and-up

Thank you for trying though. That was nice of you!
It made my mind go numb at first until I remembered that I already learned this lol

But if anyone can help me understand those crazy equations in the link I would be grateful. Or point me in a direction as to where I could learn how to understand said equations about RR interval spectral analysis and those gosh darn ANOVAS lol. I hate them and love them

Oh [insert vulgar term here] I just realized you can't zoom in on the pictures! I am so sorry guys >.<

that is too funny, but I can understand and empathize with that critique. You are totally right dude!

Big ooooof for me!

For any interested, the name of the source is: Heart rate variability response to alcohol, placebo, and emotional picture cue challenges: Effects of 0.1-Hz stimulation

Abstract

Heart rate variability (HRV) supports emotion regulation and is reduced by alcohol. Based on the resonance propertiesof the cardiovascular system, a new 0.1-Hz methodology was developed to present emotional stimuli and assess HRVreaction in participants (N536) randomly assigned to an alcohol, placebo, or control condition. Blocked picture cues(negative, positive, neutral) were presented at a rate of 5 s on, 5 s off (i.e., 0.1-Hz frequency). SDNN, pNN50, and HFHRV were reduced by alcohol, compared to the placebo and control. The 0.1-Hz HRV index was diminished byalcohol and placebo, suggesting that autonomic regulation can be affected by cognitive expectancy. The 0.1-Hz HRVindex and pNN50 detected changes in arousal during emotional compared to neutral cues, and the 0.1-Hz HRV indexwas most sensitive to negative valence. The 0.1-Hz HRV methodology may be useful for studying the intersection ofcognition, emotion, and autonomic regulation.Descriptors:Alcohol, Placebo, Emotion, HRV, 0.1-Hz resonance, Baroreflex

Looks like frequency responses and measurement of a square wave... Without really reading anything...

I can zoom in on the pictures. I still can't help you though.

Someone will come along...

What exactly are you planning on building?

Maybe you shouldnt have the answer HHmmmm ?Could be dangerous.

First of all--awesome name. My Hero Academia is such a great show

What would one build though?

WAIT A MINUTE!
I know: The Ventech Missile Defense System that was controlled by M.U.T.H.E.R.

SAUCE

...Go Team Venture!

To add: As Elon Musk stated, "There's a tremendous bias against taking risks. Everyone is trying to optimize their...covering."

To note, good sirs and/or madams, this is not just a reply to you but to the thread itself, to close it. Thank you for your analysis!

BEHOLD! THE ABRIDGED ANSWER TO THE QUESTION STATED IN THE OP

Also, the topic is Psychophysiology

ANSWER: The figure on the left is essentially an uncompressed form of the figure on the right. The figure on the right is measured in Hertz (Hz) and is a potential indicator of emotional adjustment level, hence the FFT (Fast Fourier transform) conversion. This would be an example of HF (high-frequency), since the peak in the graph on the right is within the range of 0.075 and 0.15. It is not LF (low-frequency), so we don't have to talk about that.

Thank you all for your input and for the wholesomeness.

Have a fantastic night everyone!

A pleasure as usual~

Extra source (incl. the equations)
I read the paper in your extra source link, but I didn't see anything about showing pictures, like in the question you are trying to answer. So that question in your opening post must relate to a different paper, post the link to that paper. I don't even see units on the RRI graph on the left, where the values go from approximately 600 to 800, that's 600 to 800 what, exactly? Milliseconds? If so, why doesn't it say so? The graph on the right appears to have units.

The extra source link does indeed have -nothing- to do with the academic article (other than sharing a variable). I just found it when I was refreshing myself on the jargon.

I apologize--they are from the university library and I can't really share the whole thing with you. I gave you the abstract, pictures, the title, and the authors' names. That should be enough for you to find it

The thing both articles share in common is that they reference the same variable.

All I am saying is the answer to question 11 is correct. That's the end

I appreciate the assistance! In the end we solved the problem and it's all good mate

ごめんなさい

If it helps, the graph does say "Expanded figure 1B"

You should have asked what he wanted to build.

Now you are at the crux of the issue....relativity.....ask what the intended use is before you connect the dots....there are multiple tactical applications for this data.
