Information Dissemination Analysis Using a Time-Weight Null Model: A Case Study of Sina Micro-Blog

IEEE Access, 2018
Information dissemination in a social network is constrained by the underlying structure of the network and interaction between the users, and different dissemination patterns are exhibited over time. In this paper, first, information dissemination trees

WISDoM: Characterizing Neurological Time Series With the Wishart Distribution

Frontiers in Neuroinformatics, 2021
WISDoM (Wishart Distributed Matrices) is a framework for the quantification of deviation of symmetric positive-definite matrices associated with experimental samples, such as covariance or correlation matrices, from expected ones governed by the Wishart ...

Functional structure of plant communities along salinity gradients in Iranian salt marshes

Plant-Environment Interactions, 2022
Salt marshes are unique habitats between sea or saline lakes and land that need to be conserved from the effects of global change. Understanding the variation in functional structure of plant community along environmental gradients is critical to predict

Strong Environmental Filtering Based on Hydraulic Traits Occurring in the Lower Water Availability of Temperate Forest Communities

Frontiers in Plant Science, 2022
The trait-based approaches have made progress in understanding the community assembly process. Here, we explore the key traits that may shape community assembly patterns of the same community type but within different water availabilities.

A nonparametric empirical Bayes framework for large-scale multiple testing [PDF]

, 2011
We propose a flexible and identifiable version of the two-groups model, motivated by hierarchical Bayes considerations, that features an empirical null and a semiparametric mixture model for the non-null cases.

Common spatial patterns of trees in various tropical forests: Small trees are associated with increased diversity at small spatial scales

Ecology and Evolution, 2021
Tropical forests are notable for their high species diversity, even on small spatial scales, and right‐skewed species and size abundance distributions.

Soil salinity is the main factor influencing the soil bacterial community assembly process under long-term drip irrigation in Xinjiang, China

Frontiers in Microbiology, 2023
Identifying the potential factors associated with the impact of long-term drip irrigation (DI) on soil ecosystems is essential for responding to the environmental changes induced by extensive application of DI technology in arid regions.
