The numerical study of static and dynamic characteristics of multi-layer protuberant foil bearing
Journal of Advanced Mechanical Design, Systems, and Manufacturing, 2015 Multi-layer protuberant foil bearings uses multi-layers of protuberant foils as the elastic support structure to support the smooth top foil. A numerical model with a computational method is developed in this paper to predict the characteristics of the ...

The unpredictably eruptive dynamics of spruce budworm populations in eastern Canada
Population Ecology, EarlyView.We examine historical population data for spruce budworm from several locations through the period 1930–1997, and use density‐dependent recruitment curves to test whether the pattern of population growth over time is more consistent with Royama's (1984; Ecological Monographs 54:429–462) linear R(t) model of harmonic oscillation at Green River New ...

Geographic variation in walking activity in the red flour beetle Tribolium castaneum
Population Ecology, EarlyView.This study examined whether there is geographic variation in field populations, focusing on the moving activity in the red flour beetle Tribolium castaneum. Results showed significant differences in moving activity among field populations but no correlation with latitude or meteorological factors.
