Yamabe-Type Equations on Carnot Groups

Potential Analysis, 2016
This article is concerned with a class of elliptic equations on Carnot groups depending of one real positive parameter and involving a critical nonlinearity. As a special case of our results we prove the existence of at least one nontrivial solution for a subelliptic critical equation defined on a smooth and bounded domain $D$ of the {Heisenberg group}

CEBP and ZEB2 alterations define three distinct subtypes of B‐cell acute lymphoblastic leukemia

HemaSphere, Volume 10, Issue 6, June 2026.
Abstract B‐cell acute lymphoblastic leukemia (B‐ALL) is a heterogeneous malignancy driven by diverse genetic alterations. Among these, CEBP family genes and ZEB2 are recurrently involved, yet the spectrum of genomic mechanisms and their clinical impact remain incompletely defined.

High frequency of CD95+/CD45RA− regulatory T cells defines an immunosuppressive profile associated with MDS progression

British Journal of Haematology, Volume 208, Issue 6, Page 1993-2003, June 2026.
Summary Dynamic interactions between mutated haematopoietic cells and immune cells are key drivers of myelodysplastic neoplasms (MDS) initiation and progression. Regulatory T cells (Tregs) are central mediators of immunosuppression in MDS. We thus aimed to characterize Treg subpopulations in the bone marrow (BM) of MDS patients and to explore their ...

A density result on a BV-type space on Carnot groups

Bruno Pini Mathematical Analysis Seminar
In the setting of Carnot groups (connected, simply connected and stratified Lie groups), we prove a density result for a BV-type space previously introduced in [3].

Uniform Gaussian Bounds for Subelliptic Heat Kernels and an Application to the Total Variation Flow of Graphs over Carnot Groups

Analysis and Geometry in Metric Spaces, 2013
In this paper we study heat kernels associated with a Carnot group G, endowed with a family of collapsing left-invariant Riemannian metrics σε which converge in the Gromov- Hausdorff sense to a sub-Riemannian structure on G as ε→ 0.

W2,p a priori estimates for nonvariational operators: the sharp maximal function technique

Bruno Pini Mathematical Analysis Seminar, 2018
We consider a nonvariational degenerate elliptic operator, structured on a system of left invariant, 1-homogeneous, Hörmander vector fields on a Carnot group, where the coefficient matrix is symmetric, uniformly positive on a bounded domain and the ...

Morrey–Campanato functional spaces for Carnot groups [PDF]

We shortly review the historical path of Morrey–Campanato functional spaces and the fundamentals of Carnot groups. Then, we merge these two topics, by recovering several classical results concerning regularity of Morrey-Campanato spaces in the framework ...

Uniqueness and comparison principles for semilinear equations and inequalities in Carnot groups

Advances in Nonlinear Analysis, 2018
Variants of the Kato inequality are proved for distributional solutions of semilinear equations and inequalities on Carnot groups. Various applications to uniqueness, comparison of solutions and Liouville theorems are presented.

Characterizing circadian rest–activity rhythm patterns across Alzheimer's disease continuum in Down syndrome

Alzheimer's &Dementia, Volume 22, Issue 5, May 2026.
Abstract INTRODUCTION Sleep and circadian rest–activity rhythm (RAR) disruption may bidirectionally relate to Alzheimer's disease (AD). Down syndrome (DS), the most common genetic cause of AD, presents sleep disorders, yet RAR patterns across the DS‐associated AD continuum remain uncharacterized. METHODS We analyzed 7‐day wrist actigraphy in 140 adults
