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

Exploring the Hemoglobin T to R2 Path Using Gaussian Elastic Network Correlation Map Distance

Proteins: Structure, Function, and Bioinformatics, EarlyView.
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.

Climatically suitable areas for Hylobius abietis and Hylobius pales: a global and regional analysis considering economic risks for pine production

Pest Management Science, EarlyView.
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.

Effects of Galactic Irradiation on Thermal and Electronic Transport in Tungsten

physica status solidi (b), EarlyView.
This atomic‐scale study reveals how low‐to‐mid‐energy space irradiation alters tungsten's thermal and electronic behavior, even at low defect levels. Focusing on vacancy sites in bulk and near grain boundaries, it employs two novel approaches: site‐projected thermal conductivity and the N2$^{2}$ method for the thermal and electronic response analysis ...

Noise Reduction in Nano‐Raman Spectroscopy Using Principal Component Analysis

physica status solidi (b), EarlyView.
Comparison of the intensity map of the 1168 cm−1 peak obtained from tip‐enhanced Raman spectroscopy measurements, before and after principal component analysis (PCA). The raw data (left) shows significant noise, masking the structural features of the sample.

Mapping Thermal Conductivity at the Atomic Scale: A Step toward the Thermal Design of Materials

physica status solidi (b), EarlyView.
The site‐projected thermal conductivity method resolves the local thermal conduction contribution per atom by decomposing the Green–Kubo thermal conductivity tensor under the harmonic approximation. It highlights thermally active sites and “thermal defects” within disordered or amorphous materials, enabling spatially resolved insights into atomic‐scale

On the impact of observation‐error correlations in data assimilation, with application to along‐track altimeter data

Quarterly Journal of the Royal Meteorological Society, EarlyView.
We study the impact of observation‐error correlations in data assimilation using both a simple idealised system and a more realistic configuration. A spectral analysis of data assimilation in the idealised system allows us to gain insights on the effect of observation‐error correlations, which are then validated using the realistic configuration.
