An Efficient Data Structure for Fast Mining High Utility Itemsets
Zhi-Hong Deng, Shulei Ma, He Liu
In this paper, we propose a novel data structure called PUN-list, which maintains both the utility information about an itemset and utility upper bound for facilitating the process…
Ultrafast coherent control of a hole spin qubit in a germanium quantum dot
Ke Wang, Gang Xu, Fei Gao +13
Operation speed and coherence time are two core measures for the viability of a qubit. Strong spin-orbit interaction (SOI) and relatively weak hyperfine interaction make holes in g…
Measurement of undulator section wakefield at the SXFEL test facility
He Liu, Hanxiang Yang, Nanshun Huang +5
In free electron laser facilities, almost every kind of device will generate wakefield when an electron beam passes through it. Most of the wakefields are undesired and have a nega…
HetCCL: Enabling Collective Communication For Mixed-Vendor Heterogeneous Clusters
Yuejie Wang, Tao Chang, Yuanyuan Zhao +10
Training Large Language Models (LLMs) on heterogeneous clusters presents significant challenges for collective communication, as hardware from multiple vendors introduces diverse n…
Ultrafast Liquid Water Transport Through Graphene-Based Nanochannels Measured by Isotope Labelling
Pengzhan Sun, He Liu, Kunlin Wang +3
Graphene-based laminates, with ultralong and tortuous nanocapillaries formed by simply stacking graphene flakes together, have great promises in filtration and separation. However,…
Deep Probabilistic Graph Matching
He Liu, Tao Wang, Yidong Li +3
Most previous learning-based graph matching algorithms solve the \textit{quadratic assignment problem} (QAP) by dropping one or more of the matching constraints and adopting a rela…
