On page 2403, Masashi Daido, Yukio Kawashima, and Masanori Tachikawa perform classical hybrid Monte Carlo (HMC) and path integral hybrid Monte Carlo (PIHMC) simulations to analyze the nuclear quantum effect on the hydrogenbonded structure of Watson–Crick-type adenine–thymine (A–T) and guanine–cytosine (G–C) pairs. The cover shows a schematic illustration of A–T and G–C pairs at 300 K in a path integral simulation using 16 beads. The characteristic widespread picture of bead expansion shows that the nuclear quantum effect of hydrogen atoms plays a key role in the hydrogen-bonded structure of these base pairs.
