HT-MMIOW: A Hypothesis Test approach for Microbiome Mediation using Inverse Odds Weighting
Yuka Moroishi, Zhigang Li, Juliette C. Madan +3
The human microbiome has an important role in determining health. Mediation analyses quantify the contribution of the microbiome in the causal path between exposure and disease; ho…
Toward accurate measurement of property-dependent galaxy clustering: II. Tests of the smoothed density-corrected method
Lei Yang, Zhigang Li
We present a smoothed density-corrected technique for building a random catalog for property-dependent galaxy clustering estimation. This approach is essentially base…
Data-Driven Dispatchable Regions with Potentially Active Boundaries for Renewable Power Generation: Concept and Construction
Yanqi Liu, Zhigang Li, Wei Wei +2
The dispatchable region of volatile renewable power generation (RPG) quantifies how much uncertainty the power system can handle at a given operating point. State-of-the-art dispat…
Global weak solutions for a two-component Novikov system
Zhigang Li
In this paper, we mainly consider about the existence and uniqueness of global weak solutions for the two-component Novikov system. We first recall some results and definitions of…
Toward accurate measurement of property-dependent galaxy clustering I. Comparison of the Vmax method and the "shuffled" method
Lei Yang, Yipeng Jing, Zhigang Li +1
Galaxy clustering provides insightful clues to our understanding of galaxy formation and evolution, as well as the universe. The redshift assignment for the random sample is one of…
Local well-posedness and global existence for a multi-component Novikov equation
Zhigang Li, Yuxi Hu, Xinglong Wu
Considered herein is a multi-component Novikov equation, which admits bi-Hamiltonian structure, infinitely many conserved quantities and peaked solutions. In this paper, we deduce…
IFAA: Robust association identification and Inference For Absolute Abundance in microbiome analyses
Zhigang Li, Lu Tian, A. James O'Malley +8
The target of inference in microbiome analyses is usually relative abundance (RA) because RA in a sample (e.g., stool) can be considered as an approximation of RA in an entire ecos…
Cosmological parameter estimation from large-scale structure deep learning
Shuyang Pan, Miaoxin Liu, Jaime Forero-Romero +4
We propose a light-weight deep convolutional neural network (CNN) to estimate the cosmological parameters from simulated 3-dimensional dark matter distributions with high accuracy.…
MarZIC: A Marginal mediation model for Zero-Inflated Compositional mediators with applications to microbiome data
Quran Wu, A. James O'Malley, Janaka S. S. Liyanage +9
The human microbiome can contribute to pathogeneses of many complex diseases by mediating disease-leading causal pathways. However, standard mediation analysis methods are not adeq…
Conditional regression based on a multivariate zero-inflated logistic normal model for microbiome relative abundance data
Zhigang Li, Katherine Lee, Margaret R. Karagas +4
The human microbiome plays critical roles in human health and has been linked to many diseases. While advanced sequencing technologies can characterize the composition of the micro…
BSG alignment of SDSS galaxy groups
Zhigang Li, Yougang Wang, Xiaohu Yang +3
We study the alignment signal between the distribution of brightest satellite galaxies (BSGs) and the major axis of their host groups using SDSS group catalog constructed by Yang e…
