Weak Gravitational Galaxy-Galaxy Lensing

open access: yes, 2014
This thesis describes the theory and applications of weak gravitational galaxy-galaxy lensing. In particular, constraining the galaxies’ mean halo mass M200, concentration parameter c and ellipticity of the dark matter halo distribution ε1l. Weak gravitational lensing is the distortion of background galaxy images by matter distributions along the line ...

Residual eDNA in eRNA Extracts Skews eRNA‐Based Biodiversity Assessment: Call for Optimised DNase Treatment

open access: yesMolecular Ecology Resources, Volume 26, Issue 2, February 2026.
ABSTRACT Environmental RNA (eRNA) metabarcoding has rapidly emerged as a powerful tool for assessing contemporary biodiversity patterns across diverse ecosystems. However, the potential for false positive detections caused by co‐extracted environmental DNA (eDNA) remains unquantified.

Deciphering the Transcriptomic Signatures of Aging Across Organs in Mice

open access: yesAging Cell, Volume 25, Issue 2, February 2026.
Comprehensive transcriptomic profiling of eight mouse organs across six ages reveals how aging reshapes biological processes. Trajectory and network analyses distinguish shared and organ‐specific signatures, charting the molecular landscape of systemic aging.

Identification of key gut microbiota and microbial QTL in contributing to the significant differences in body weight between two Chinese local chicken breeds

open access: yesAnimal Genetics, Volume 57, Issue 1, February 2026.
Abstract Previous studies have identified genetic loci that are associated with both feed conversion efficiency and gut microbiota in chickens, suggesting that interactions between the host genome and gut microbiota may influence chicken growth. However, the number of microbial QTL and gut microbiota associated with chicken body weight remains largely ...

Improved taxonomic and gene sampling advance the knowledge of deep relationships within Macrodasyida (Gastrotricha)

open access: yesCladistics, Volume 42, Issue 1, Page 25-45, February 2026.
Abstract Advances in Macrodasyida (Gastrotricha) phylogenetics, fuelled by new species discoveries and molecular data, are reshaping taxonomic classifications. Molecular analyses suggest polyphyly in Cephalodasyidae and Macrodasyidae, yet insufficient sampling continues to obscure precise relationships.

Models in Decision‐Making Under Risk and Uncertainty

open access: yesJournal of Economic Surveys, Volume 40, Issue 1, Page 304-320, February 2026.
ABSTRACT This paper systematically compares dominant frameworks for modeling decision‐making under risk and uncertainty, evaluating their theoretical trade‐offs and practical relevance for economic research. We establish key criteria for model selection—including predictive accuracy, descriptive realism, computational tractability, and ecological ...
