Fast way to determine pp-collision time at the SPD experiment

The main task of this work is to find a fast and robust way to determine pp-collision time t0 at the SPD experiment. Using physics motivations, from the input flux of reconstructed particles' tracks we identify a subset of pions which is used to calculate the unbiased estimation of the event collision time. The uncertainty of the estimation is about 30 ps. This method is fast (less than 300 ns per event) and reliable, thus it will allow to process the high flux of input events at the SPD experiment.Comment: Submitted to Physics of Elementary Particles and Atomic Nuclei, Letter

Rejuvenating apples

Apples are an amazing fruit. We have heard much about useful properties of apples. Everyone is likely to have read many fairy tales in the childhood that told us about rejuvenating apples. You are sure to remember, for example, "The Tale of the good fellow-Udalets, rejuvenating apples and live water". We wondered whether the apples are so beneficial indeed, what their useful properties are, and what they depend onЯблоки – это удивительный фрукт. Мы много слышали о полезных свойствах яблок. И, наверно, каждый из вас знаком с детства со сказками, речь в которых идёт о молодильных яблоках. Например, в «Сказке о молодце-удальце, молодильных яблоках и живой воде». Нам стало интересно, а правда ли яблоки настолько полезны, в чем проявляются их полезные свойства, от чего они завися
