Blow-ups of minimal surfaces in the Heisenberg group

Analysis and Geometry in Metric Spaces
In this article, we revise Monti’s results on blow-ups of H-perimeter minimizing sets in Hn{{\mathbb{H}}}^{n}. Monti demonstrated that the Lipschitz approximation of the blow-up, after rescaling by the square root of the excess, converges to a limit ...

Mikhlin-Type H^p Multiplier Theorem on the Heisenberg Group

Axioms
The classical Fourier multiplier theorem by Mikhlin in Hardy spaces is extended to the Heisenberg group. The proof relies on the theories of atom and molecule functions and the property of special Hermite functions.

Prenucleation Species Dictate Foreign Ion Incorporation in the Biomineral Precursor Amorphous Calcium Carbonate

Advanced Functional Materials, Volume 36, Issue 36, 4 May 2026.
ACC forms via aggregating prenucleation clusters that gatekeep its chemical composition. Ion identity steers the path: Ba and Sr substitute Ca in clusters, thereby inhibiting nucleation, with a dose‐dependent switch of Sr to induction. Mg partitions into Mg‐rich and Mg‐poor clusters; the latter form ACC, expelling Mg.

Heisenberg Group-Based Digital Signatures for Secure Communications

IEEE Access
This paper proposes a new digital signature algorithm that employs the Heisenberg group over a prime field and exploits its structure to provide strong cryptographic properties. The developed scheme involves the Heisenberg group within a commutator-based

Alignment of the Starlings: Learning With Generative AI

Future Humanities, Volume 4, Issue 1, May 2026.
ABSTRACT I will argue that answers to normative questions concerning the place of generative AI in learning rest on answers to ontological questions regarding (1) precisely what is happening when a human ‘interacts’ with generative AI and (2) What is distinctive about organic learning as opposed to currently existing ‘machine learning’ (3) What is the ...

T Cell Receptor Repertoires Across the Continuum of Vascular, Myocardial, and Age‐Related Diseases

Immunological Reviews, Volume 339, Issue 1, May 2026.
ABSTRACT Cardiovascular diseases (CVD) are shaped by a complex interplay with immune mechanisms. In particular, the distinct roles of antigen‐specific T cell mechanisms are emerging as critical determinants across a broad spectrum of conditions, ranging from atherosclerosis, myocardial infarction (MI), heart failure (HF), and myocarditis. Because these

Lorentzian homogeneous structures with indecomposable holonomy

Journal of the London Mathematical Society, Volume 113, Issue 5, May 2026.
Abstract For a Lorentzian homogeneous space, we study how algebraic conditions on the isotropy group affect the geometry and curvature of the homogeneous space. More specifically, we prove that a Lorentzian locally homogeneous space is locally isometric to a plane wave if it admits an Ambrose–Singer connection with indecomposable, non‐irreducible ...
