We study expansion/contraction properties of some common classes of mappings of the Euclidean space $\mathsf{R}^n$, $n\ge 2$, with respect to the distance ratio metric. The first main case is the behavior of Möbius transformations of the unit ball in $\mathsf{R}^n$ onto itself.

Comprehensive Peptide Profiling Reveals the Influence of Streptococcus Thermophilus, Lactobacillus Delbrueckii Subsp. bulgaricus, and Endogenous Milk Proteases on the Hydrolysis of Milk Proteins During Early‐Stage Lactic Acid Fermentation

ChemFoodChem, EarlyView.
Untargeted peptide profiling investigates how S. thermophilus, Lb. bulgaricus, and endogenous milk enzymes impact proteolysis during early‐stage milk fermentation. ≥ 3000 identified peptides show the strongest influence of LB on the peptide profile and number of bioactive peptides. Shorter peptides are mostly formed by LB and hydrolyzed by ST.
