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 ...

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.

Cordes nonlinear operators in Carnot groups
Electronic Journal of Differential Equations, 2015 Our aim is to obtain L^p estimates for the second-order horizontal derivatives of the solutions for a nondivergence form nonlinear equation in Carnot groups.

Adherence to Treatment in Allergic Rhinitis During the Pollen Season in Europe: A MASK‐air Study
Clinical &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 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 \(u \in C^\infty\).

Developmental Medicine &Child Neurology, EarlyView.Abstract Children with neurological impairment (CNI) are at increased risk of malnutrition because of functional, medical, and socioeconomic challenges. However, difficulties in obtaining reliable anthropometric measurements and differences in body composition limit the usefulness of conventional nutritional indicators.

Nucleophilic Trifluoromethoxylation of Acyl Chlorides: A Direct Route to Trifluoromethyl Esters
Advanced Synthesis &Catalysis, Volume 368, Issue 18, 19 September 2026.A new method for the synthesis of the underexplored trifluoromethyl carboxylic esters using acyl chlorides as readily available feedstocks and in situ‐generated AgOCF3 from silver fluoride and the trifluoromethyl para‐toluenesulfonate has been designed. The reaction works on a large variety of aromatic and aliphatic acyl chlorides, while minimizing the

A density result on a BV-type space on Carnot groups
Bruno Pini Mathematical Analysis SeminarIn 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].

A Unified Theory of Tropical Cumulonimbus Cloud Concentration and High Cloud Fraction
Journal of Advances in Modeling Earth Systems, Volume 18, Issue 9, September 2026.Abstract A variety of processes lead to tropical cumulonimbus clouds and anvils. Convection draws moist air into clouds from below, resupplying water lost to precipitation. Cloud condensate mixes vigorously, setting the cloud concentration near the cloud top where air detrains into surrounding clear‐sky regions.

The Theorem of Busemann-Feller-Alexandrov in Carnot Groups [PDF]
Communications in Analysis and Geometry, 2004 The authors prove a version of the Busemann-Feller-Alexandrov theorem for the class of weakly \(H\)-convex functions in Carnot groups. Precisely, let \(\mathbf G\) be a Carnot group of step \(r=2\) with a system \(X_1,\dots,X_m\) of bracket generating left-invariant vector fields.
