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

Almost Eigenvalues and Eigenvectors of Almost Mathieu Operators
The almost Mathieu operator is the discrete Schr\"odinger operator $H_{\alpha,\beta,\theta}$ on $\ell^2(\mathbb{Z})$ defined via $(H_{\alpha,\beta,\theta}f)(k) = f(k + 1) + f(k - 1) + \beta \cos(2\pi \alpha k + \theta) f(k)$. We derive explicit estimates

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

Elements of dynamic parameters modification and sensitivity [PDF]
Structural modifications can cause changes in the matrices of some elements. Depending on the type of structure, or a desired change, a group of elements can be modified.

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.

Exploring the Hemoglobin T to R2 Path Using Gaussian Elastic Network Correlation Map Distance
ABSTRACT Proteins are dynamic and undergo conformational changes. These changes may affect the motions executed by different regions of the proteins and are reflected in the motion correlation map. A method to accurately measure these changes is presented and exemplified on a set of tetrameric Hemoglobin structures.

Climate suitability maps indicate a high economic risk for Pinus‐producing municipalities in Brazil if Hylobius abietis and Hylobius pales invade, highlighting the need for preventive measures. Abstract BACKGROUND The weevils Hylobius abietis and Hylobius pales are major pests of pine species within their native ranges.
