MRT-SS Calculator: An R Shiny Application for Sample Size Calculation in Micro-Randomized Trials
Nicholas J. Seewald, Ji Sun, Peng Liao
The micro-randomized trial (MRT) is a new experimental design which allows for the investigation of the proximal effects of a "just-in-time" treatment, often provided via a mobile…
A Topology-Aware Localized Update Strategy for Graph-Based ANN Index
Song Yu, Shengyuan Lin, Shufeng Gong +7
The graph-based index has been widely adopted to meet the demand for approximate nearest neighbor search (ANNS) for high-dimensional vectors. However, in dynamic scenarios involvin…
On the Ultraviolet Divergence in QED
Ji Sun
The well-known physical equivalence drawn from hole theory is applied in this article. The author suggests to replace, in the part of Feynman diagram which cannot be fixed by exper…
