ODIN: Object Density Aware Index for CkNN Queries over Moving Objects on Road Networks
Ziqiang Yu, Xiaohui Yu, Tao Zhou +3
We study the problem of processing continuous k nearest neighbor (CkNN) queries over moving objects on road networks, which is an essential operation in a variety of applications.…
The Rigid Pham-Brieskorn Threefolds
Michael Chitayat, Adrien Dubouloz
We show that a -dimensional Pham-Brieskorn hypersurface in such that a…
Algebra of Nonlocal Boxes and the Collapse of Communication Complexity
Pierre Botteron, Anne Broadbent, Reda Chhaibi +2
Communication complexity quantifies how difficult it is for two distant computers to evaluate a function f(X,Y), where the strings X and Y are distributed to the first and second c…
Contact non-squeezing at large scale via generating functions
Maia Fraser, Sheila Sandon, Bingyu Zhang
Using SFT techniques, Eliashberg, Kim and Polterovich (2006) proved that if for some integer then there is no contact squeezing in $\mathbb{R}^{2n}…
Quantum recurrences in the kicked top
Amit Anand, Jack Davis, Shohini Ghose
The correspondence principle plays an important role in understanding the emergence of classical chaos from an underlying quantum mechanics. Here we present an infinite family of q…
Combiner and HyperCombiner Networks: Rules to Combine Multimodality MR Images for Prostate Cancer Localisation
Wen Yan, Bernard Chiu, Ziyi Shen +8
One of the distinct characteristics in radiologists' reading of multiparametric prostate MR scans, using reporting systems such as PI-RADS v2.1, is to score individual types of MR…
