Structural and Optical Characterization of Pure and Lanthanum Substituted Nd1–xLaxAlO3 Prepared by Sol–Gel Method

ChemistryOpen, EarlyView.
The variations in crystal‐field splitting parameter Δ for the pure and elongated polyhedra. The present studies offer the new methodology to tune crystal‐field energy by means of lattice distortion. The present results are useful for fine tuning of laser energy.

Eigenpairs of adjacency matrices of balanced signed graphs

Special Matrices
In this article, we study eigenvalues λ\lambda and their associated eigenvectors xx of the adjacency matrices AA of balanced signed graphs. Balanced signed graphs were first introduced and studied by Harary to handle a problem in social psychology ...

Genetic diversity and population structure of pedunculate oaks (Quercus robur) in Wytham Woods

PLANTS, PEOPLE, PLANET, EarlyView.
Genetic diversity underpins forest resilience and adaptation, yet centuries of human activity have reshaped woodland ecosystems worldwide. We studied the population genetics of pedunculate oaks (Quercus robur) in Wytham Woods, UK, across stands with different ages and management histories.

Integrating target capture with whole genome sequencing of recent and natural history collections to explain the phylogeography of wild‐growing and cultivated cannabis

PLANTS, PEOPLE, PLANET, EarlyView.
Cannabis has been used by humans for millennia, resulting in diverse landraces and uses. Its complex legal status and economic importance make sampling wild‐growing populations difficult, limiting past studies to modern cultivars with low genetic diversity. Our research provides crucial insights into the genetic diversity of wild‐growing and cultivated

On the eigenvalue and eigenvector derivatives of a general matrix [PDF]

The existence of differentiable eigenvalues and eigenvectors for a general matrix is addressed. The eigenspace which contains differentiable eigenvectors is determined and computed by using the concept of subspace intersection in conjunction with the ...

Comparative Dynamics Enables Discovery of Embedded Bacterial Ferredoxin Domains in Large Redox Enzymes

Proteins: Structure, Function, and Bioinformatics, EarlyView.
ABSTRACT Bacterial ferredoxins are small iron–sulfur binding proteins that function as soluble electron shuttles between redox enzymes in the cell. Their simple 2×(β–α–β) fold, central metabolic function, and ubiquity across all kingdoms of life have led to the proposal that ferredoxins were likely among the earliest proteins.
