can EEG be built with arduino as a controller?

Aiming for: game and behavior research in post PhD level.

Hello, can you recommend to me any architecture of machine vision that allows me to detect at least one object with a low-resolution camera (or high, as well) with high FPS (frame per second) more than 15 with Raspberry Pi5 (8Gb RAM)?

Hello everyone,

It is known to us that vacancy exists in the solid phases, which contributes to the diffusion mechanisms.

My question is, does vacancy exist in a liquid phase? If it exists, does it affect diffusion mechanisms? Alternatively speaking, what is the diffusion scenario in the liquid phase?

It should be noted that this discussion is aimed at the metallic systems, or at least inorganic systems.

Looking forward to any answer....

Thanks!

Our research team met one question on calculating EEG relative power and absolute power at this stage.

When we integrated all negative and positive amplitude/power data in five EEG bands (delta, theta, alpha, beta, gamma), a few relative power results became huge (i.e., 440%(44.44) or even over 1000%). We thought these values were abnormal results. The reason is that the integration result of five EEG bands with negative and positive power values could be 1 or 2 as the denominator, but the numerator could be very large for the integration of one specific band(i.e., delta). The relative power calculation is (sum of spectral power in the band)/(sum of spectral in all bands)

The attached image showed some negative and positive spectral power values.

Therefore, we would like to ask whether we need first to transfer negative value to absolute value to consider relative power or absolute power. Normally, the relative power should be around 0-100%.

Can experts help us? Could experts please share some references with us?

I confront this problem when I using data from Neurosky. The eight EEG powers are: delta (0.5 - 2.75Hz), theta (3.5 - 6.75Hz), low-alpha (7.5 - 9.25Hz), high-alpha (10 - 11.75Hz), low-beta (13 - 16.75Hz), high-beta (18 - 29.75Hz), low-gamma (31 - 39.75Hz), and mid-gamma (41 - 49.75Hz). I have found the meanning of some, for example, Delta reflects sleep and unconscious. However, the resource decribing the meaning of low-Alpha, high-Alpha, low-Gamma, mid-Gamma is too much little.

I have received the following polite email request from Medical Research Archives, European Society of Medicine a number of times.

Is it legitimate? Would you mind sharing your thoughts if you have any experience of this kind? Thanks

Dear Dr. Yegnanew A. Shiferaw,

If you have a few minutes I wanted to discuss your COVID-19 research. I am serving as the editor of a special theme issue on Advancements in COVID-19 which will be released by the European Society of Medicine next year and I was thinking that something related to your work on "Regime shifts in the COVID-19 case fatality rate dynamics: A Markov-switching autoregressive model analysis" would be interesting to include in the issue. Perhaps you could tell me more about your research in this area.

This could be in the form of a research article or even a review article.

Might this be a possibility?

Sincerely,

I have been struggling to get endorsement for putting preprint in arXiv, but I a unable to get it. What is the best method to get endorsement in arXiv for physics or mathematics?

I have a piece of code about image deblurring. It contains no random components. The same code running on two different computers results in different results (one is on Matlab 2014a and the other is on Matlab 2016a). Have you ever met this situation?
