Efficiency comparison between mean and log-rank tests for recurrent event time data
SCIENCE IN CHINA SERIES A-MATHEMATICS, 52(6), 1169–1180.
author keywords: asymptotic relative efficiency; frailty model; log-rank test; proportional mean test; recurrent events; robust variance estimation
TL;DR:
Analysis of two popular nonparametric tests for recurrent event time data shows that the log-rank test that only makes use of time to the first occurrence could be more efficient than the test for mean occurrence rates that makesUse of all available recurrence times, provided that subject-to-subject variation ofrecurrence times is large.

author keywords: Bayesian inference; correlation nonstationarity; heterogeneity; hierarchical model; random effect; variance nonstationarity
TL;DR:
Application is made to a real dataset on electric potential measurements in a field containing a metal pole and the finding is that the approach captures the pole's impact on small‐scale variability of the electric potential process.

A stochastic neighborhood conditional autoregressive model for spatial data
COMPUTATIONAL STATISTICS & DATA ANALYSIS, 53(8), 3033–3046.
TL;DR:
An extension of CAR model where the selection of the neighborhood depends on unknown parameter(s) is proposed, called a Stochastic Neighborhood CAR (SNCAR) model, which shows flexibility in accurately estimating covariance structures for data generated from a variety of spatial covariance models.

Sorghum sudangrass as a summer cover and hay crop for organic fall cabbage production
RENEWABLE AGRICULTURE AND FOOD SYSTEMS, 24(3), 225–233.
author keywords: Sorghum bicolor x Sorghum sudanense; Brassica oleracea; no-tillage; conservation tillage; organic vegetable production; cover cropping; weed management
TL;DR:
The findings suggest that the potential for growers to manage a cover crop also as a hay crop does exist; however, SS may not be a compatible cover crop species for organic fall cabbage production due to high amounts of re-growth.

Plant species loss decreases arthropod diversity and shifts trophic structure
ECOLOGY LETTERS, 12(10), 1029–1039.
author keywords: Arthropods; biodiversity; consumers; ecosystem function; herbivores; insects; long-term; plant diversity; predators; trophic structure
MeSH headings : Animals; Arthropods / physiology; Biodiversity; Extinction, Biological; Food Chain; Plant Development; Plants; Population Density
TL;DR:
The results demonstrate that, over the long term, the loss of plant species propagates through food webs, greatly decreasing arthropod species richness, shifting a predator-dominated trophic structure to being herbivore dominated, and likely impacting ecosystem functioning and services.

MeSH headings : Animals; Databases, Genetic; Genome; Genome-Wide Association Study / methods; Genomics / methods; Humans; Markov Chains; Polymorphism, Single Nucleotide
TL;DR:
A powerful data-driven procedure [pooled local index of significance (PLIS)], that controls the false discovery rate (FDR) at the nominal level, is proposed that is shown to be optimal in the sense that it has the smallest false negative rates (FNR) among all valid FDR procedures.
