Creep model of bond-degradation in deep granite based on variable radius particle clump
Scientific ReportsThe creep failure of rocks is related to its microstructure, external loading and time. A nonlinear yield model was introduced to describe the variation in the cohesion and friction angle with plastic strain and intergranular stress.

Dysregulation of U12‐Type Splicing in Lupus Neutrophils
Arthritis &Rheumatology, EarlyView.Objective Neutrophil dysfunction is a hallmark of systemic lupus erythematosus (SLE), but its molecular basis remains unclear. This study explores transcriptional and posttranscriptional changes in low‐density granulocytes (LDGs), a proinflammatory neutrophil subset expanded in SLE, focusing on NADPH oxidase (Nox) function and minor intron splicing ...
