On Rectifiable Measures in Carnot Groups: Existence of Density
The Journal of Geometric Analysis, 2022 AbstractIn this paper, we start a detailed study of a new notion of rectifiability in Carnot groups: we say that a Radon measure is$${\mathscr {P}}_h$$Ph-rectifiable, for$$h\in {\mathbb {N}}$$h∈N, if it has positiveh-lower density and finiteh-upper density almost everywhere, and, at almost every point, it admits a unique tangent measure up to multiples.

Movement Disorders, EarlyView.Abstract Background The Huntington's Disease Integrated Staging System (HD‐ISS) provides a framework for staging HD but does not incorporate fluid biomarkers. Objective The aim of this study was to examine neurofilament light chain (NfL) and mutant huntingtin (mHTT) and total tau across HD‐ISS stages and their associations with genetic burden ...

Multicomplexes on Carnot Groups and Their Associated Spectral Sequence
The Journal of Geometric Analysis, 2023 AbstractThe aim of this paper is to give a thorough insight into the relationship between the Rumin complex on Carnot groups and the spectral sequence obtained from the filtration on forms by homogeneous weights that computes the de Rham cohomology of the underlying group.

Small, EarlyView.This work presents a biofriendly carbon nanotube yarn artificial muscle operating either as an in‐air unipolar actuator or as a self‐powered ionotronic strain sensor. Using a non‐volatile eutectogel‐derived electrolyte, the system achieves up to 2.9% contraction and 0.5 mV/% strain sensing sensitivity.

APPROXIMATIONS OF SOBOLEV NORMS IN CARNOT GROUPS [PDF]
Communications in Contemporary Mathematics, 2011 This paper deals with a notion of Sobolev space W1, pintroduced by Bourgain, Brezis and Mironescu by means of a seminorm involving local averages of finite differences. This seminorm was subsequently used by Ponce to obtain a Poincaré-type inequality.

High Voltage, EarlyView.ABSTRACT This paper provides an overview of high‐temperature superconducting (HTS) cables in DC systems, with a focus on their deployment in high‐voltage DC (HVDC) networks. The assessment of HTS cable properties—such as extremely low electrical resistance, high current‐carrying capacity and a compact geometry—and their comparison with those of ...

A proof of Hörmander’s theorem for sublaplacians on Carnot groups [PDF]
Nonlinear Analysis, 2015 Let \(G\) be a Carnot group and let \(\mathcal{L}\) be its left-invariant sub-Laplacian. As a consequence of Hörmander's theorem, \(\mathcal{L}\) is hypoelliptic, that is, for every distribution \(u\) on \(G\), if \(\mathcal{L}u \in C^\infty\), then \(u \in C^\infty\).

Acta Psychiatrica Scandinavica, EarlyView.ABSTRACT Introduction Suicidal ideation and behaviors (SIB) are common among individuals at clinical high risk for psychosis (CHR‐P), but their relationship with the overall clinical profile remains unclear. This study aimed to identify sociodemographic/clinical factors associated with SIB in CHR‐P individuals and to examine whether subthreshold ...

Alimentary Pharmacology &Therapeutics, EarlyView.In this randomized, double‐blind trial in Mexican adults with erosive oesophagitis, tegoprazan did not significantly improve the primary 4‐week ITT healing endpoint versus pantoprazole (88.9% vs. 79.4%; p = 0.33), but produced faster symptom improvement. Encouraging per‐protocol and severe‐oesophagitis findings warrant confirmation.
