Worldwide variation in shape and size of orca (Orcinus orca) saddle patches

Marine Mammal Science, Volume 41, Issue 1, January 2025.
Abstract The global distribution of Orcinus orca (orcas/killer whales) encompasses populations which differ from each other. Saddle patch shapes and sizes were compared for nearly 4,000 individuals, in 48 geographically or ecologically divided groups/populations/ecotypes (GP/E), in four Ocean Basins.

Anisotropic Exchange in LiCuVO$_4$ probed by ESR [PDF]

, 2002
We investigated the paramagnetic resonance in single crystals of LiCuVO$_4$ with special attention to the angular variation of the absorption spectrum. To explain the large resonance linewidth of the order of 1 kOe, we analyzed the anisotropic exchange ...

Ambient Noise Tomography of Northern Borneo Reveals Evidence of Subduction and Post‐Subduction Processes

Journal of Geophysical Research: Solid Earth, Volume 129, Issue 11, November 2024.
Abstract The region of northern Borneo in South East Asia sits within a post‐subduction setting formed by the recent termination of two sequential but opposed subduction systems. In this study we use seismic data from a recent temporary array deployment to image the crustal velocity structure beneath northern Borneo using a two‐stage Bayesian trans ...

The many ways toward punctuated evolution

Palaeontology, Volume 67, Issue 5, September/October 2024.
Abstract Punctuated equilibria is a theory of evolution that suggests that species go through periods of stability followed by sudden changes in phenotype. This theory has been debated for decades in evolutionary biology, but recent findings of stasis and punctuated change in evolutionary systems such as tumour dynamics, viral evolution, and artificial

Spin Hamiltonian Parameters for Cu(II)−Prion Peptide Complexes from L-Band Electron Paramagnetic Resonance Spectroscopy [PDF]

, 2011
Cu(II) is an essential element for life but is also associated with numerous and serious medical conditions, particularly neurodegeneration. Structural modeling of crystallization-resistant biological Cu(II) species relies on detailed spectroscopic ...

Radioaktives Cäsium im Fisch der Barentssee weiterhin abnehmend [PDF]

, 1997
A decrease of 137Cs concentration in cod flesh from Barents Sea is shown by six years random sampling. This reduction runs parallel to reduced emissions from the nuclear fuel reprocessing plant Sellafield (Great Britain).

Modeling of magnetization reversal processes in magnetic circuits of measuring transformers [PDF]

, 2015
The article describes methods for modeling transient regimes in current and voltage transformers. In most studies measuring transformers are modeled in a stationary mode to determine their metrological characteristics. However, for safe uninterrupted

Polaron and bipolaron dispersion curves in one dimension for intermediate coupling

, 2006
Bipolaron energies are calculated as a function of wave vector by a variational method of Gurari appropriate for weak or intermediate coupling strengths, for a model with electron-phonon interactions independent of phonon wave vectors and a short-ranged ...
