Extracellular Vesicles From Limosilactobacillus johnsonii Enhance Milk Fat Synthesis by Inducing CD36 Dynamic Palmitoylation and Activating PPARγ Signalling

open access: yesJournal of Extracellular Vesicles, Volume 14, Issue 8, August 2025.
Extracellular vesicles from Limosilactobacillus johnsonii reach the mammary gland through the gut‐mammary axis, where their palmitic acid (C16:0) induce the dynamic changes in CD36 palmitoylation in mammary epithelial cells, thereby facilitating fatty acid uptake as substrates and enhance milk fat synthesis in HC11 cells via PPARγ signalling.

Understanding Interphases and Interfaces of Battery Materials at the Nanoscale

open access: yesSmall, Volume 21, Issue 34, August 28, 2025.
Decoding Battery Interfaces. This review examines the significant challenges in characterizing battery interfaces—thin, complex layers vital for performance. Advanced techniques are surveyed, including in situ methods, and discuss data interpretation pitfalls.

c horizontal convexity on Carnot groups

open access: yes, 2010
Given a real-valued function $c$ defined on the cartesian product of a generic Carnot group $\G$ and the first layer $V_1$ of its Lie algebra, we introduce a notion of $c$ horizontal convex ($c$ H-convex) function on $\G$ as the supremum of a suitable family of affine functions; this family is defined pointwisely, and depends strictly on the horizontal

Transitive bi-Lipschitz group actions and bi-Lipschitz parameterizations

open access: yes, 2012
We prove that Ahlfors 2-regular quasisymmetric images of the Euclidean plane are bi-Lipschitz images of the plane if and only if they are uniformly bi-Lipschitz homogeneous with respect to a group.

Chaotic Geodesics in Carnot Groups

open access: yes, 1997
The group of real 4 by 4 upper triangular matrices with 1s on the diagonal has a left-invariant subRiemannian (or Carnot-Caratheodory) structure whose underlying distribution corresponds to the superdiagonal. We prove that the associated subRiemannian geodesic flow is not completely integrable.
