Osteohistological characterization of notosuchian osteoderms: Evidence for an overlying thick leathery layer of skin

Journal of Morphology, Volume 284, Issue 1, January 2023., 2023
The perpendicular insertion of Sharpey's fibers in the external cortex suggests the presence of a thick leathery skin layer overlying notosuchian osteoderms. Although intramembranous ossification is the main process involved in the development of crocodyliform osteoderms, we reported a case of metaplastic development.

Multi‐proxy reconstruction of the Holocene vegetation and land use dynamics in the Julian Alps, north‐west Slovenia

Journal of Quaternary Science, Volume 38, Issue 1, Page 107-122, January 2023., 2023
Abstract Small mountain lakes are natural archives for understanding long‐term natural and anthropogenic impact on the environment. This study focused on long‐term (last ca. 13 000 years) vegetation changes and sedimentary processes in the catchment area of Lake Planina pri jezeru (1430 m a.s.l.) by using mineralogical, geochemical and palynological ...

A Search for Exoplanets in Short-Period Binary Star Systems [PDF]

Journal of Astronomy and Space Sciences, 2012
This paper reports the progress of a search for exoplanets with S-type orbits in short-period binary star systems. The selected targets have stellar orbital periods of just a few days. These systems are eclipsing binaries so that exoplanet transits, if

Eclipsing Binary Stars in Nearby Galaxies [PDF]

Astrophysics and Space Science, 2006
We briefly discuss the survey programme we are conducting to detect eclipsing binaries in local group galaxies. Some lightcurves from studies of M31, IC 1613 and NGC 6822 are presented along with details of future work.

Eclipsing Binaries in Multiple Star Systems [PDF]

Symposium - International Astronomical Union, 1992
Although the majority of the known eclipsing binaries are in systems which consist of only the two eclipsing components, a significant number of them do occur as components of triple star systems or higher order multiple star systems. In this context this term is restricted to those systems whose components are in closed orbits.

Accurate fundamental parameters of eclipsing binary stars [PDF]

Proceedings of the International Astronomical Union, 2004
The study of detached eclipsing binaries is one of the most powerful ways to investigate the properties of individual stars and stellar systems. We present preliminary masses, radii and effective temperatures for the eclipsing binary WW Aurigae, which is composed of two metallic-lined A-type stars.

A transiting companion to the eclipsing binary KIC002856960 [PDF]

, 2012
We present an early result from an automated search of Kepler eclipsing binary systems for circumbinary companions. An intriguing tertiary signal has been discovered in the short period eclipsing binary KIC002856960. This third body leads to transit-like

A catalogue of temperatures for Kepler eclipsing binary stars [PDF]

Monthly Notices of the Royal Astronomical Society, 2013
We have combined the Kepler Eclipsing Binary Catalogue with information from the HES, KIS and 2MASS photometric surveys to produce spectral energy distribution fits to over 2600 eclipsing binaries in the catalogue over a wavelength range of 0.36 to 2.16 .

Single‐cell/nanoparticle trajectories reveal two‐tier Lévy‐like interactions across bacterial swarms

VIEW, Volume 3, Issue 6, December 2022., 2022
Bacterial community is a typical model system to study the behavior of multicellular organization, how millions of cells are organized, and how they communicate efficiently microscopically on large spatiotemporal scales have attracted a lot of attention.

An Adaptive Optics Survey of Stellar Variability at the Galactic Center [PDF]

, 2018
We present a $\approx 11.5$ year adaptive optics (AO) study of stellar variability and search for eclipsing binaries in the central $\sim 0.4$ pc ($\sim 10''$) of the Milky Way nuclear star cluster.
