Passerine stopover physiology: weather variability does not alter corticosterone dynamics after sea crossing

open access: yesJournal of Avian Biology, Volume 2025, Issue 4, July 2025.
Migration is an energy‐intensive phase of birds' life cycle, often including the crossing of large ecological barriers during non‐stop flights. Corticosterone (CORT), an adrenocortical hormone also known as the stress hormone, generally rises at the onset of migration to facilitate and sustain high‐energy metabolism.

Australian Ocean surface waves dataset from SAR

open access: yesGeoscience Data Journal, Volume 11, Issue 4, Page 638-654, October 2024.
In this article, a first regional Synthetic Aperture Radar (SAR) ocean surface waves dataset, containing directional ocean swell spectra measurements from Europe's Sentinel‐1 A and B satellites, is described. The goal is to support marine scientific and industrial research in Australia.

The Generic Mapping Tools and Animations for the Masses

open access: yesGeochemistry, Geophysics, Geosystems, Volume 25, Issue 6, June 2024.
Abstract Generic Mapping Tools (GMT) is a well‐known set of software originally developed for geosciences, allowing scientists in climate and solid earth disciplines to routinely create publish‐ready maps and graphics. However, GMT users rarely make animations despite their undeniable benefit for understanding and teaching dynamic processes. As reading

Material Metaphors for Literary Form: Robert Burton's ‘Perused’ Copy of Theatrum Urbium Italicarum (1599)

open access: yesRenaissance Studies, Volume 38, Issue 2, Page 185-205, April 2024.
Abstract This article gives a detailed description and analysis of Robert Burton's copy of Theatrum urbium italicarum, a Venetian ‘city‐atlas’ produced in 1599 by the engraver and publisher Pietro Bertelli. Burton's copy of the book is especially noteworthy because it has had a number of the maps removed.

Acoustic radiation from a pulsating spherical cap set on a spherical baffle near a hard/soft flat surface

open access: yes, 2004
Radiation of sound from a spherical piston, set in the side of a rigid sphere, undergoing harmonic radial surface vibrations in an acoustic halfspace is analyzed in an exact fashion using the classical method of separation of variables.

The Most Remote Point of Loxodrome from Orthodrome [PDF]

open access: yes, 1998
U radu je prikazan problem određivanja najudaljenije točke loksodrome od ortodrome pri čemu obje prolaze dvjema zadanim točkama. Najprije je objašnjena klasična metoda rješavanja problema prema Kavrajskome, a zatim je iznijeta vlastita metoda.

Robust Bayesian inference in Iq-Spherical models [PDF]

open access: yes, 1992
The class of multivariate lq-spherical distributions is introduced and defined through their isodensity surfaces. We prove that, under a Jeffreys' type improper prior on the scale parameter, posterior inference on the location parameters is the same for

On Convex Subcomplexes of Spherical Buildings and Tits’ Center Conjecture [PDF]

open access: yes, 2009
In this thesis we study convex subcomplexes of spherical buildings. In particular, we are interested in a question of J. Tits which goes back to the 50’s, the so-called Center Conjecture.

Eccentricity effects on acoustic radiation from a spherical source suspended within a thermoviscous fluid sphere

open access: yes, 2003
Acoustic radiation from a spherical source undergoing angularly periodic axisymmetric harmonic surface vibrations while eccentrically suspended within a thermoviscous fluid sphere, which is immersed in a viscous thermally conducting unbounded fluid ...
