Genetic Insights Into Human‐Driven Hybridization, Cultural Shifts, and Ecological Consequences of Feral Pigs (Sus scrofa) in Hawai‘i

open access: yesEcology and Evolution, Volume 16, Issue 1, January 2026.
Polynesian pigs were brought to the Hawaiian Islands with Polynesian settlement in the mid‐1200s and represent part of the cultural legacy of Hawai‘i. Yet, the introduction of European pigs since 1778 and onward has put into question the ancestral composition of contemporary animals, and conservation efforts have been challenged by tension between the ...

Stellar Hydrodynamics in Radiative Regions

open access: yes, 2003
We present an analysis of the response of a radiative region to waves generated by a convective region of the star; this wave treatment of the classical problem of ``overshooting'' gives extra mixing relative to the treatment traditionally used in ...

Influence of catchment lithology on debris‐flow fan morphology, sedimentology and evolution—Field evidence from the White Mountains, southern California, USA

open access: yesEarth Surface Processes and Landforms, Volume 50, Issue 13, October 2025.
Morphology of the (a) Sacramento Canyon fan (with a catchment dominated by batholitic bedrock) and (b) Gunter Creek fan (with a catchment dominated by sedimentary bedrock) at the foot of the White Mountains, California, highlighting the differences between fans fed by contrasting lithologies.

Main-Sequence and sub-giant stars in the Globular Cluster NGC6397: The complex evolution of the lithium abundance

open access: yes, 2009
Thanks to the high multiplex and efficiency of Giraffe at the VLT we have been able for the first time to observe the Li I doublet in the Main Sequence (MS) stars of a Globular Cluster.

Li isotopes in metal-poor halo dwarfs, a more and more complicated story [PDF]

open access: yes, 2009
The nuclei of the lithium isotopes are fragile, easily destroyed, so that, at variance with most of the other elements, they cannot be formed in stars through steady hydrostatic nucleosynthesis.

Associations of Skin Biomechanical Properties With Biological Aging Clocks and Longitudinal Changes in Intrinsic Capacity in Adults Aged 20–93: The INSPIRE‐T Project

open access: yesAging Cell, Volume 24, Issue 10, October 2025.
This study assessed skin biomechanics using the Cutometer in 441 community‐dwelling adults aged 20–93 from the INSPIRE‐T cohort. We demonstrated that skin elasticity and viscoelasticity parameters were associated with the intrinsic capacity (IC) score, a functional marker of healthy aging encompassing cognition, locomotion, psychology, vitality, and ...

Lithium-7 surface abundance in pre-MS stars. Testing theory against clusters and binary systems

open access: yes, 2012
The disagreement between theoretical predictions and observations for surface lithium abundance in stars is a long-standing problem, which indicates that the adopted physical treatment is still lacking in some points.

Comparison of Ising magnet on directed versus undirected Erdos-Renyi and scale-free network [PDF]

open access: yes, 2006
Scale-free networks are a recently developed approach to model the interactions found in complex natural and man-made systems. Such networks exhibit a power-law distribution of node link (degree) frequencies n(k) in which a small number of highly ...
