Constructing two-level nonlinear mixed-effects crown width models for Moso bamboo in China
Frontiers in Plant Science, 2023 Bamboo crown width (CW) is a reliable index for evaluating growth, yield, health and vitality of bamboo, and light capture ability and carbon fixation efficiency of bamboo forests. Based on statistical results produced from fitting the eight basic growth

Logarithmic Variance for the Height Function of Square-Ice
Communications in Mathematical Physics, 2022 In this article, we prove that the height function associated with the square-ice model (i.e.~the six-vertex model with $a=b=c=1$ on the square lattice), or, equivalently, of the uniform random homomorphisms from $\mathbb Z^2$ to $\mathbb Z$, has logarithmic variance. This establishes a strong form of roughness of this height function.

Population and species neighbor identity impact trait–trait relationships and plant performance
Population Ecology, EarlyView.We evaluated how populations and species identity influence plant performance and trait outcomes in mixtures, and assessed trait variation among populations of two forb species native to the western United States (Dieteria canescens and Heterotheca villosa) following three interaction treatments (single‐population monoculture, two‐population mixture ...

Effects of chronic browsing on life‐history traits of an irruptive large herbivore population
Population Ecology, EarlyView.This study aimed to determine the relationship between diet quality, body mass, and size (hind foot length), and female reproduction and sought to identify the mechanism by which high density under severe food limitations is maintained. Our results demonstrated that sika deer introduced to Nakanoshima Island have maintained high densities through high ...

Population Ecology, EarlyView.This study examines the demographic dynamics of two seabird populations on Tromelin Island, 15 years after the eradication of brown rats. The results indicate that these populations are in good health and are expected to continue growing until breeding sites are saturated in about a century.

Generalised variance functions for longitudinal survey data
Statistical Theory and Related Fields, 2019 In this research, we propose longitudinal generalised variance functions (LGVFs) to produce convenient estimates of variances by incorporating time effect into modelling.

On Decompositions of Decision Function Quality Measure
Известия Иркутского государственного университета: Серия "Математика", 2020 A comparative analysis of two approaches to the decomposition of quality criterion of decision functions is carried out. The first approach is the bias-variance decomposition.
