We performed molecular dynamics (MD) simulations of telomeric single-stranded DNA and POT1 for 100 ns. The distance between $$C_alpha$$ (POT1) and O5' (telomeric ssDNA) is calculated to verify the binding system for 100 ns MD. We then calculated the distance between the bases of telomeric DNA ends and the root mean square deviation and gyration radius in single and binding states. We compared the root mean square fluctuations between single and binding states and calculated the number of hydrogen bonds between POT1 and telomeric DNA. There are many hydrogen bonds between Gln94 and the first guanine of the closest TTAGGG sequence in telomeric single-stranded DNA. These Gln94 and the guanine have a large difference in root mean square fluctuation between single and binding states. We found that Gln94 and guanine are important components of the binding system, and they are related to its stability.

A focal-plane Si detector setup applied to the spectroscopy of the element 115 $$alpha$$-decay chains was reported. Results of the digital signal analysis for preamplifier signals and of the event-by-event $$alpha$$-energy loss correction analysis were presented. The detectors consist of five double-sided Si strip detectors (DSSSD) arranged as a box, and signals from one side of the detector at the bottom of the box were digitally processed. Energy losses of $$alpha$$ particles detected by two Si detectors at the bottom and a side differs event-by-event, because each $$alpha$$ particle passed through two dead layers with a certain tilted angle. By correcting for the energy loss of each $$alpha$$ event using the angle of the $$alpha$$-particle emission extracted from the detected positions, we succeeded in improving the $$alpha$$ energy resolution significantly.
