Landscape factors influencing predation on capercaillie nests by two competing mesopredators: pine marten and red fox

open access: yesWildlife Biology, EarlyView.
Predation by pine martens Martes martes and red foxes Vulpes vulpes is an important factor influencing the population dynamics of capercaillie Tetrao urogallus. However, there is a knowledge gap regarding the relative effects of these mesopredators on the reproductive success of capercaillie. To better understand how various landscape factors influence

Compact Riemannian Manifolds with Homogeneous Geodesics

open access: yesSymmetry, Integrability and Geometry: Methods and Applications, 2009
A homogeneous Riemannian space (M = G/H,g) is called a geodesic orbit space (shortly, GO-space) if any geodesic is an orbit of one-parameter subgroup of the isometry group G. We study the structure of compact GO-spaces and give some sufficient conditions

The moving‐beam diffraction geometry: the DIAD application of a diffraction scanning probe

open access: yesJournal of Applied Crystallography, EarlyView.
We introduce the moving‐beam diffraction geometry as implemented at the Dual Imaging and Diffraction beamline at Diamond Light Source, and provide a quantitative assessment of the precision offered by this geometry and the nearest‐neighbor calibration method.Understanding the interactions between microstructure, strain, phase and material behavior is ...

Inscribing geodesic circles on the face of the superstratum

open access: yesJournal of High Energy Physics
We use families of circular null geodesics as probes of a family of microstate geometries, known as (1, 0, n) superstrata. These geometries carry a left-moving momentum wave and the behavior of some of the geodesic probes is very sensitive to this ...

Habitat imprinting in breeding territory selection of a long‐lived bird of prey

open access: yesJournal of Animal Ecology, EarlyView.
A unique long‐term dataset has allowed this study of an important habitat selection mechanism, habitat imprinting, in a species which is typically extremely challenging to study. It gives us better understanding of the role of early experience in selection of breeding sites in long‐lived species with high breeding site fidelity.

Optimal three-dimensional biped walking pattern generation based on geodesics

open access: yesInternational Journal of Advanced Robotic Systems, 2017
The innovative three-dimensional humanoid biped gait planning method using geodesics is introduced in this article. In order to control three-dimensional walking, the three-dimensional linear inverted pendulum model is studied in our energy-optimal gait ...
