Jitter analysis of a superconducting nanowire single photon detector
AIP Advances, 2013 Jitter is one of the key parameters for a superconducting nanowire single photon detector (SNSPD). Using an optimized time-correlated single photon counting system for jitter measurement, we extensively studied the dependence of system jitter on the bias

Astrophysical Insights into Radial Velocity Jitter from an Analysis of 600 Planet-search Stars [PDF]
Astronomical Journal, 2020 Radial velocity (RV) detection of planets is hampered by astrophysical processes on the surfaces of stars that induce a stochastic signal, or "jitter," which can drown out or even mimic planetary signals. Here, we empirically and carefully measure the RV

Physical mechanisms of timing jitter in photon detection by current-carrying superconducting nanowires [PDF]
Physical Review B, 2017 We studied timing jitter in the appearance of photon counts in meandering nanowires with different fractional amount of bends. Timing jitter, which is the probability density of the random time delay between photon absorption in current-carrying ...

Jitter: Random Jittering Loss Function [PDF]
2021 International Joint Conference on Neural Networks (IJCNN), 2021 Regularization plays a vital role in machine learning optimization. One novel regularization method called flooding makes the training loss fluctuate around the flooding level. It intends to make the model continue to random walk until it comes to a flat loss landscape to enhance generalization.
