Adherence to Treatment in Allergic Rhinitis During the Pollen Season in Europe: A MASK‐air Study

open access: yesClinical &Experimental Allergy, Volume 55, Issue 3, Page 226-238, March 2025.
In a study assessing mobile health data, (i) adherence to rhinitis medication was highest for oral antihistamines and lowest for azelastine‐fluticasone, (ii) in weeks of partial adherence, azelastine‐fluticasone was associated with lower levels of reported rhinitis symptoms than other medication classes.

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

open access: yesBruno 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].

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

open access: yesAdvances 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.

Metric currents, differentiable structures, and Carnot groups [PDF]

open access: yes, 2011
We examine the theory of metric currents of Ambrosio and Kirchheim in the setting of spaces admitting differentiable structures in the sense of Cheeger and Keith.

Rigidity of fiber-preserving quasisymmetric maps

open access: yes, 2015
We show that fiber-preserving quasisymmetric maps are biLipschitz. As an application, we show that quasisymmetric maps on Carnot groups with reducible first stratum are ...

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

open access: yesAnalysis 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

open access: yesBruno 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 ...

On‐Chip Perovskite Coolers

open access: yesAdvanced Materials Technologies, Volume 11, Issue 1, 8 January 2026.
Scaling of 3D‐integrated electronics exacerbates thermal bottlenecks, motivating solid‐state on‐chip cooling beyond convection and immersion. This perspective reviews optical refrigeration, electroluminescent cooling, and thermoelectrics for localized, vibration‐free heat removal.

Future Perspective On Materials, Electrochemistry, and Cell Concepts for Redox‐Mediated CO2 Direct Air Capture Scenarios

open access: yesChemistryEurope, Volume 4, Issue 1, January 2026.
Direct air capture (DAC) of carbon dioxide (CO2) emerges as a key strategy for climate crisis mitigation. Redox‐mediated electrochemical carbon capture offers a promising route for energy‐efficient DAC. This perspective discusses recent advances in the field, highlighting key challenges, such as oxygen interference at low CO2 concentrations, and ...

Privileged Coordinates and Nilpotent Approximation of Carnot Manifolds, I. General Results

open access: yes, 2018
In this paper we attempt to give a systematic account on privileged coordinates and the nilpotent approximation of Carnot manifolds. By a Carnot manifold it is meant a manifold with a distinguished filtration of subbundles of the tangent bundle which is ...
