Evolutionary Relationships and Genetic Diversity in the Southern Siberian Populations of the Saker Falcon (Falco cherrug), a Young and Endangered Species

open access: yesDiversity
Studying intraspecific differentiation in closely related species is essential to clarify the phylogenetic relationships and mechanisms of early stage speciation, particularly in evolutionarily young lineages affected by human-driven population declines.

Practical Applications of Secondary/Extractive Electrospray Ionization (SESI): A Versatile Tool for Real‐Time Chemical Analysis

open access: yesMass Spectrometry Reviews, Volume 45, Issue 2, Page 392-428, March/April 2026.
ABSTRACT In the 1980s, researchers discovered the remarkable ability of electrospray plumes to effectively ionize gas‐phase molecules via secondary ionization. Around 20 years later—coinciding with the ambient mass spectrometry revolution—secondary electrospray ionization (SESI) and extractive electrospray ionization (EESI) coupled to mass spectrometry

Equivalence Between the Co‐Rotational Finite Element Method and the Absolute Coordinate Formulation in Multibody Dynamics

open access: yesInternational Journal for Numerical Methods in Engineering, Volume 127, Issue 2, 30 January 2026.
ABSTRACT Geometric nonlinearity arises in problems involving large displacements and rotations, where traditional linear assumptions fail. In the finite element community, several formulations have been developed to address these complexities; the corotational finite element formulation (CRF) has proven to be an efficient alternative to generic total ...

Risk assessment in the plateau pika (Ochotona curzoniae): intensity of behavioral response differs with predator species

open access: yesBMC Ecology, 2020
Background The ability of a prey species to assess the risk that a predator poses can have important fitness advantages for the prey species. To better understand predator–prey interactions, more species need to be observed to determine how prey ...

Evaluation of a New Methylimidazole‐Containing Thiosemicarbazone as a Cu+/Cu2+‐Targeting Ligand in the Context of Alzheimer's Disease

open access: yesChemistry – A European Journal, Volume 32, Issue 1, 2 January 2026.
HXE modulates Cu(Aβ) interaction, reducing ROS production and shifting peptide aggregation in the presence of Cu from toxic amorphous aggregates to less harmful fibrillar structures. These findings highlight HXE potential to interfere with Cu‐induced oxidative stress and aggregation pathways relevant to AD.
