Copula‐based joint modelling of emergency department visits with time‐varying dependence

Canadian Journal of Statistics, EarlyView.
Abstract Jointly modelling multiple correlated count time series is essential in health services research, where outcomes like emergency visits for mental health and substance use often evolve together. Ignoring these dependencies can obscure meaningful trends and limit the effectiveness of policy evaluation.

Decoupling of microbial diversity and ecosystem function driven by metal ions and nutrient shifts across dry-wet seasons in a temperate river basin

Global Ecology and Conservation
Microbial communities are key drivers of biogeochemical cycles and water-quality regulation in freshwater ecosystems. However, how these communities respond to climatic and environmental changes at the watershed scale across dry and wet seasons remains ...

Exponentially‐constrained Gaussian mixture model for quantifying vertical development of water‐conducting fracture zones in lithologically stratified mining roofs

Deep Underground Science and Engineering, EarlyView.
This study proposes an exponentially‐constrained Gaussian mixture model (EcGMM) to quantify vertical fracture heterogeneity in stratified roof strata. The model integrates a piecewise exponential decay term capturing global stress dissipation with Gaussian components representing localized fracture intensification at lithological interfaces.

Loess records

Loess is an eolian deposit, composed mainly of silt grains, which can be identified in the field as a distinct sedimentary body. It covers a significant portion of the land surface of the Earth and is one of the most important terrestrial archives of long-term dust deposition.

Future warming enhances rates of population increase of arthropod crop pests globally

Ecography, EarlyView.
Arthropod herbivores cause severe crop yield losses worldwide. Global warming is expected to shift their ranges, phenologies and performances, highlighting the need for improved forecasts of their potential expansion and impacts on food security. After decades of experimental research on thermal biology of arthropod crop pests, available data and tools

Clay Mineralogy of Red Clay Deposits from the Central Carpathian Basin (Hungary): Implications for Plio/Pleistocene Chemical Weathering and Paleoclimate [PDF]

, 2013
Geochemical and mineralogical studies of palaeosols provide essential information for palaeoclimatic and palaeoenvironmental interpretation of continental deposits and can present a proxy for palaeoclimate.
