The hyperbolicity constant of infinite circulant graphs

open access: yesOpen Mathematics, 2017
If X is a geodesic metric space and x1, x2, x3 ∈ X, a geodesic triangle T = {x1, x2, x3} is the union of the three geodesics [x1x2], [x2x3] and [x3x1] in X.

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 ...

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.

Thermodynamic geodesics in Bardeen regular black hole: conventional vs. modified geometrothermodynamics metrics

open access: yesEuropean Physical Journal C: Particles and Fields
Thermodynamic geometry allow us to study the microscopic behavior of black hole system by defining a metric structure in thermodynamic phase space. Among the various thermodynamic metric structures, metrics defined by geometrothermodynamics (GTD) are ...

Aggregated Compensation Peer Group Disclosure and Managerial Labor Market Competition: A Network Analysis

open access: yesJournal of Accounting Research, EarlyView.
ABSTRACT In this paper, we develop novel measures of managerial labor market classification and competition by constructing networks of compensation benchmarking peers disclosed in proxy statements. These networks represent firms’ relative positions within the managerial labor market.

Infinite geodesic rays in the space of Kahler potentials

open access: yes, 2002
In this paper we explore the connection between special degenerations of algebraic manifolds and geodesics in the space of Kahler metrics. We provide a new and general geometric construction of nontrivial solutions for the geodesic equation.

Exploring the Metric Systems of Medieval New Towns in Central Europe: Reconstruction of Urban Plot Scheme Using Cosine Quantogram and Modular Analysis

open access: yesArchaeometry, EarlyView.
ABSTRACT This study examines plot divisions and units of measurement in regular medieval new towns in Central Europe, with a particular focus on historical Silesia. By applying the cosine quantogram method alongside GIS‐referenced cartographic sources and modular analysis, the research reconstructs the spatial organization of urban layouts. The results

On Pseudospherical Smarandache Curves in Minkowski 3-Space

open access: yesJournal of Applied Mathematics, 2014
In this paper we define nonnull and null pseudospherical Smarandache curves according to the Sabban frame of a spacelike curve lying on pseudosphere in Minkowski 3-space. We obtain the geodesic curvature and the expressions for the Sabban frame’s vectors

Strolling along gauge theory vacua

open access: yesJournal of High Energy Physics, 2017
We consider classical, pure Yang-Mills theory in a box. We show how a set of static electric fields that solve the theory in an adiabatic limit correspond to geodesic motion on the space of vacua, equipped with a particular Riemannian metric that we ...
