As regards the brain studies the only I did so far is a check whether I have a brain..
And this is a prove ....I have a prove .... Do you recognise, maybe I should turn to the side …. As regards the brain studies the only I did so far is a check whether I have a brain.. (But we may change it in the future ...???) W trakcie zwiedzania okazało się, że poszukiwani są ochotnikcy do badań, których celem było lepsze zrozumienia zaburzeń centralnego układu nerwowego. Wpisałem się więc na listę ochotników. Już po około miesiącu otrzymałem z prośbą o zgodę na zrobienie zdjęcia tomograficznego Było ono niezbędne dla porównania wyników badań zdrowych osób z osobami z zaburzeniami ruchowymi wywołanymi chorobą Parkinsona . Rysunek 2. Na rysunku pokazany jest rozkład gęstości receptorów adenozynowych A1 w moim mózgu w dniu Pokazane są przekroje: poprzeczny (lewa kolumna), czołowy (środkowa kolumna) oraz strzałkowy (prawa kolumna). Im jaśniejsze barwy tym większe stężenie. Górny rząd przedstawia obrazy wykonane techniką NMR, środkowy – techniką PET, a dolny jest nałożeniem obu obrazów. Przedmiotem badań był rozkład gęstości receptorów adenozynowych A1. Badania wymagały nieco poświęceń ponieważ już dzień wcześniej musiałem zaprzestać picia kawy, ze względu na to, że molekuły adenozyny są podobne do cząsteczek kofeiny, które podobno blokują receptory adenozynowe w mózgu. Na dodatek w Pozytonowej Emisyjnej Tomografii radiofarmaceutyk podaje się pacjentowi dożylnie, czego, z jakiś niezrozumiałych ogólnie powodów, unikam jak ognia. Po około 90 minutach badań tomografem PET wzięto mnie jeszcze do sali obok i zrobiono mi obraz tomograficzny mózgu metodą magnetycznego rezonansu jądrowego. Z przeprowadzonych badań otrzymałem na pamiątkę zdjęcia pokazane na rysunku 2 może lepiej: ... zrobienie zdjęcia tomograficznego – chodziło o porównanie zdrowych osób z osobami z zaburzeniami ruchowymi wywołanymi chorobą Parkinsona

Ortho-positronium life-time tomography
Y.H. Wang et al., PRA89 (2014) [G1] Y.H. Wang et al., Phys. Rev. A 89 (2014) G2] Upper panel shows positronium atom and the probability density of spatial distribution of electron and positron in the positronium [G1]. Left figure in the lower panel indicates main decays modes of the two ground states of positronium with orbital angular momentum L=0. The para-positronium (1S0) and ortho-positronium (3S1). The substates of positronium are denoted according to the conventional spectroscopic notation: 2S+1LJ, where S denotes total spin of the electron-positron pair, and J denotes the total angular momentum. Right figure in the lower panel shows the SEM image of the porous aerogel structure. The SBA-15 material as well as the image were performed by the applicants of this project at the UMSC University in Lublin. Free spaces between molecules (holes) with the size of the order of 10 nm are visible. The upper-right figure shows an example of the structure of the silica aerogel [G2] indicating free voids where the positronium atoms may be trapped.

It is an open question whether or not the three-photon entanglement can be reduced to the two-photon entanglement and decoherence of the two-photon states does imply decoherence in photon triplets. This hypothesis can be tested by comparison of measured two- and three-photon correlation functions. There exist three-photon states maximizing the Greenberger-Horn-Zeilinger (GHZ) entanglement and they can be used to test quantum local realism versus quantum mechanics.

But epsilon^2 = 20 to 40 smaller efficiency
It is important to note that the cost of J-PET does not increase with the increase of the FOV epsilon^2 = 20 to 40 smaller efficiency But Solid angle > factor of ~5 600 ps --> 200ps – 300ps --> factor of 1m instead of ~17 cm > factor of 10 N layers in the strip-PET ----> factor N2 Conservatively: for N= > total factor of ~ 100 Lower dose by factor of 3 (100 better / 30 worse)
