c horizontal convexity on Carnot groups

, 2010
Given a real-valued function $c$ defined on the cartesian product of a generic Carnot group $\G$ and the first layer $V_1$ of its Lie algebra, we introduce a notion of $c$ horizontal convex ($c$ H-convex) function on $\G$ as the supremum of a suitable family of affine functions; this family is defined pointwisely, and depends strictly on the horizontal

Monthly Energy, Exergy, Environmental, and Economic Performance and Green Hydrogen Production Analysis of a Flat‐Plate Solar Collector‐Driven Organic Rankine Cycle System Under Variable Mass Flow and Irradiance

ChemistryOpen, Volume 15, Issue 7, July 2026.
The feasibility of using a hybrid flat‐plate solar collector–organic Rankine cycle–proton exchange membrane system for the generation of electricity, heat, and hydrogen simultaneously is analyzed. The energy efficiency of the solar thermal system reaches 23.82%, and hydrogen production of up to 13.62 kg/month is achieved while reducing CO2 emissions ...

Validation of the Milan Score Using Prolonged Wireless PH Monitoring

Alimentary Pharmacology &Therapeutics, Volume 64, Issue 2, Page 177-185, July 2026.
The Milan Score, a high‐resolution manometry‐derived tool, predicts pathological GERD on 96‐h wireless pH monitoring with high specificity and positive predictive value, maintaining robust discriminative performance across both typical and atypical symptom profiles and outperforming single HRM parameters as a standalone manometric parameter.

Are West African Heat‐Lows Analogous to Dry Tropical Cyclones?

International Journal of Climatology, Volume 46, Issue 8, 30 June 2026.
Heat‐lows qualitatively resemble dry tropical cyclones (TCs), though their underlying physics has yet to be compared. In this study, we show that West African transient heat‐low climatology correlates well with TC potential intensity generalised over land.

Differential forms in Carnot groups: a variational approach

Bruno Pini Mathematical Analysis Seminar, 2011
Carnot groups (connected simply connected nilpotent stratified Lie groups) can be endowed with a complex of ``intrinsic'' differential forms. In this paper we want to provide an evidence of the intrinsic character of Rumin's complex, in the spirit of the
