Abstract Harmonic mode-locking, realized actively or passively, is an effective technique for increasing the repetition rate of ultrafast lasers.It is critically important to understand how a harmonically mode-locked pulse train responds to external perturbations and noise, so as to make sure that it is stable and resistant to noise.Here, in a seri
The size of proxy signature secret key in proxy signature scheme based on read more lattice basis delegation in fixed di-mension or bonsai tree is greater than that of original signature secret key.Aiming at the situation above, a new efficient proxy signature scheme is proposed.The random oracles are combined in the scheme and a smaller vector nor
Time-resolved x-ray crystallography (TR-X) at synchrotrons and free electron lasers is a promising technique for recording dynamics of molecules at atomic resolution.While experimental methods for TR-X have proliferated and matured, data analysis is often difficult.Extracting small, time-dependent changes in signal is frequently a bottleneck for pr
