Machine Learning Diagnosis and Local Shrinkage of Covariance-Level Pathologies in SEM
MathematicsNon-convergence in small-sample structural equation modeling (SEM) is frequently driven by localized pathologies in the sample covariance matrix—specific covariance patterns that, for a given model specification, substantially elevate the risk of non ...

FEBS Letters, EarlyView.Proteostasis and the gut microbiota play a key role in shaping host physiology. Microbiota‐derived metabolites, vitamins, and RNA modulate host proteostasis. Findings from model systems, including C. elegans, indicate microbes can either stabilize or disrupt host proteostasis.

Fisher F Test with signifi cantly low values in small samples [PDF]
Revista Română de Statistică, 2011 Testing for differences between groups is usually done with the Fisher-F test. In practice, it has been known to return unusually small, but significant values.

From mice to humans—divergent strategies for intestinal homeostasis and regeneration
FEBS Letters, EarlyView.Recent advances such as organoid genome editing, xenotransplantation, imaging, and whole‐genome sequencing have enabled direct studies of human intestinal stem cells (ISCs). These studies reveal species‐specific features, including slower ISC proliferation, distinct injury responses, slower somatic mutation accumulation in humans, and an inverse ...

Design and analysis strategies for robust microbiome ageing research
FEBS Letters, EarlyView.The gut microbiome changes with age and associates with age‐related morbidity and mortality, establishing it as a potential biomarker and intervention target for ageing. Realising this potential requires methodological rigour, yet distinguishing biological signals from methodological artefacts remains challenging across cohorts. This review provides an
