Sampling with replacement vs Poisson sampling: a comparative study in optimal subsampling

Kavli Affiliate: Jing Wang | First 5 Authors: Jing Wang, Jiahui Zou, HaiYing Wang, , | Summary: Faced with massive data, subsampling is a commonly used technique to improve computational efficiency, and using nonuniform subsampling probabilities is an effective approach to improve estimation efficiency. For computational efficiency, subsampling is often implemented with replacement or through […]

Semi-inclusive Diffractive Deep Inelastic Scattering at Small-$x$

Kavli Affiliate: Feng Yuan | First 5 Authors: Yoshitaka Hatta, Bo-Wen Xiao, Feng Yuan, , | Summary: Inspired by a recent study of Iancu, Mueller and Triantafyllopoulos [1] and earlier papers by Golec-Biernat and Wusthoff [2,3], we propose semi-inclusive diffractive deep inelastic scattering (SIDDIS) to investigate the gluon tomography in the nucleon and nuclei at […]

The initial conditions for young massive cluster formation in the Galactic Centre: convergence of large-scale gas flows

Kavli Affiliate: Luis C. Ho | First 5 Authors: Bethan A. Williams, Daniel L. Walker, Steven N. Longmore, A. T. Barnes, Cara Battersby | Summary: Young massive clusters (YMCs) are compact ($lesssim$1 pc), high-mass (>10${}^4$ M${}_{odot}$) stellar systems of significant scientific interest. Due to their rarity and rapid formation, we have very few examples of […]

Ensemble Clustering via Co-association Matrix Self-enhancement

Kavli Affiliate: Ran Wang | First 5 Authors: Yuheng Jia, Sirui Tao, Ran Wang, Yongheng Wang, | Summary: Ensemble clustering integrates a set of base clustering results to generate a stronger one. Existing methods usually rely on a co-association (CA) matrix that measures how many times two samples are grouped into the same cluster according […]

A neural network model for timing control with reinforcement

Kavli Affiliate: Jing Wang | First 5 Authors: Jing Wang, Yousuf El-Jayyousi, Ilker Ozden, , | Summary: How do humans and animals perform trial-and-error learning when the space of possibilities is infinite? In a previous study, we used an interval timing production task and discovered an updating strategy in which the agent adjusted the behavioral […]

Gravothermal solutions of SIDM halos: mapping from constant to velocity-dependent cross section

Shengqi Yang, Xiaolong Du, Zhichao Carton Zeng, Andrew Benson, Fangzhou Jiang | Summary: [[{“value”:”The scale-free gravothermal fluid formalism has long proved effective in describing the evolution of self-interacting dark matter halos with a constant dark matter particle cross section. However, whether the gravothermal fluid solutions match numerical simulations for velocity-dependent cross-section scenarios remains untested. In […]

Proximity-Induced Superconductivity in Epitaxial Topological Insulator/Graphene/Gallium Heterostructures

Kavli Affiliate: Ke Wang | First 5 Authors: Cequn Li, Yi-Fan Zhao, Alexander Vera, Omri Lesser, Hemian Yi | Summary: The introduction of superconductivity to the Dirac surface states of a topological insulator leads to a novel state of matter known as a topological superconductor. A topological superconductor may host Majorana zero modes, the braiding […]
