Coverage‐based rarefaction fails to quantify relative species richness
Oikos, Volume 2026, Issue 11, November 2026.Coverage‐based rarefaction (CBR) is a high‐profile tool for assessing biodiversity that provides relative species richness estimates by leveraging the Good‐Turing index u to interpolate. In contrast to alternatives such as the Shannon and Simpson indices, CBR's main appeal is providing values in units of species. CBR is tested against a series of other

Journal of Transportation Safety & Security, 2017 ABSTRACTMany studies investigate contributing factors of intersection crashes, but very limited studies focus on cashes on the intersection approach. It is important to address the characteristics of intersection-approach crashes to better understand intersection safety.

Modeling the Frequency of Cyclists’ Red-Light Running Behavior Using Bayesian PG Model and PLN Model
Discrete Dynamics in Nature and Society, 2016 Red-light running behaviors of bicycles at signalized intersection lead to a large number of traffic conflicts and high collision potentials. The primary objective of this study is to model the cyclists’ red-light running frequency within the framework ...

Alexandria Engineering JournalIn this article, we described a novel class of distributions that can be analyzed in complex and skewed real data sets. We called the proposed distribution as compound Poisson log-normal model, and it obtained by compounding the truncated Poisson and log-

Journal of Applied Entomology, Volume 150, Issue 9, Page 1280-1288, November 2026.ABSTRACT Methyl salicylate (MeSA) is an herbivore‐induced plant volatile (HIPV) known to attract natural enemies of herbivores; however, its effectiveness as a semiochemical across diverse cropping systems and broad geographic regions remains unclear. In this 2‐year field study, we sampled natural enemies using MeSA‐baited and unbaited (control) yellow

Non‐Central Wishart Random Matrices in Structural Dynamics: A Modal‐Basis Approach
International Journal for Numerical Methods in Engineering, Volume 127, Issue 20, 30 October 2026.ABSTRACT This article develops a non‐parametric stochastic computational model for linear structural dynamics based on a reduced non‐central Wishart (NCW) random matrix formulation. The objective is to represent uncertainty in the mass and stiffness matrices while preserving the matrix properties required for modal and frequency‐domain analysis ...

geoCount: An R Package for the Analysis of Geostatistical Count Data
Journal of Statistical Software, 2015 We describe the R package geoCount for the analysis of geostatistical count data. The package performs Bayesian analysis for the Poisson-lognormal and binomial-logitnormal spatial models, which are subclasses of the class of generalized linear spatial ...

Traffic Distribution of IM Services
ITM Web of Conferences, 2016 With the proposition of new opinion that the distribution of many human activities follows heavy-tailed distribution rather than Poisson distribution, the research on human behaviors has received widely attention.
