In many applications of regression discontinuity designs, the running variable used to assign treatment is only observed with error. We show that, provided (i) correctly classifies assignment and (ii) affects conditional means potential outcomes smoothly, ignoring measurement error nonetheless yields an estimate a causal interpretation: average effect for units whose equals cutoff. Possibly aft...

Continuous-variable measurement-device-independent quantum key distribution (CV-MDI-QKD) allows remote parties to share information-theoretical secure keys while defending all the side-channel attacks on measurement devices. However, transmission distance and secret rate are quite limited due high untrusted equivalent excess noise in Gaussian modulation. More particularly, extremely high-effici...

With the increasing use of mobile GPS (global positioning system) devices, a large volume of trajectory data on users can be produced. In most existing work, trajectories are usually divided into a set of stops and moves. In trajectories, stops represent the most important and meaningful part of the trajectory; there are many data mining methods to extract these locations. DBSCAN (density-based...

Aiming at solving the uncertainty of knowledge in variable precision fuzzy soft rough set model. Firstly, from perspectives approximated and equivalent approximation space, measurement methods model are defined, such as information granularity, entropy, etc; Secondly, many related theorems given proved, monotonicity obtained when relation satisfies inclusion condition; Finally, feasibility vali...
