Weakening Processes in Carbonate‐Hosted Faults: Phyllosilicate Microlayers and Injections Along the Mattinata Fault (Southern Italy)

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 5, May 2026.
Abstract Micrometric phyllosilicate films along fault slip surfaces (SSs) can drastically reduce friction, yet they are unexpected in clay‐poor carbonate platforms. We inquire how a major carbonate‐hosted, seismogenic strike‐slip fault can develop weak slip interfaces and undergo dynamic weakening despite an intrinsically strong host rock.

Using Multiple Diagnostic Methods for Occupational Asthma Assessment

The Clinical Respiratory Journal, Volume 20, Issue 5, May 2026.
PC20 variability demonstrated higher diagnostic accuracy than PEFR monitoring in occupational asthma (OA), with a sensitivity of 90% and specificity of 92%. PEFR alone resulted in a 22.2% misclassification rate. Incorporating PC20 variability into diagnostic evaluation may reduce misdiagnosis and improve clinical outcomes in high‐exposure settings ...
