Optimal Noise-Adding Mechanism in Additive Differential Privacy
TL;DR: In this article, the authors derived the optimal noise probability distribution with a probability mass at the origin for a single real-valued query function under a general cost-minimization framework.
Journal ArticleDOI

Electrochemical impedance spectroscopy evidence of dimethyl-silicon-oil enhancing O2 transport in a porous electrode
M.B. Ji,Zidong Wei,Siguo Chen,Meirong Xia,Qing Zhang,Xueqiang Qi,Xiaosong Hu,Wei Ding,Ling Jie Li +8 more
TL;DR: In this paper, the effect of DMS on the oxygen reduction reaction (ORR) was evaluated using electrochemical impedance spectroscopy (EIS) spectra, and it was shown that DMS reduces the oxygen diffusion resistance as well as the charge transfer resistance in the flooded state.

Optimal Noise-Adding Mechanism in Additive Differential Privacy
TL;DR: This work derives the optimal $(0, \delta)-differentially private query-output independent noise-adding mechanism for single real-valued query function under a general cost-minimization framework, and identifies a probability concentration phenomenon in the continuous setting.
