Partial interior regularity for sub-elliptic systems with Dini continuous coefficients in Carnot groups: the sub-quadratic controllable case

Boundary Value Problems, 2017
We consider nonlinear sub-elliptic systems with Dini continuous coefficients for the case 1 < m < 2 $1 ...

Bio‐Friendly Artificial Muscles Based on Carbon Nanotube Yarns and Eutectogel Derivatives

Advanced Functional Materials, Volume 36, Issue 15, 19 February 2026.
Solid‐state artificial muscles based on coiled commercial carbon nanotube yarns coated with eutectogel derivatives exhibit unipolar actuation through selective ion intercalation. Combining polyanionic and polycationic gels enables enhanced contractile stroke and high energy density.

Constructing Hölder maps to Carnot groups

Journal of the American Mathematical Society
In this paper, we construct Hölder maps to Carnot groups equipped with a Carnot metric, especially the first Heisenberg group H \mathbb {H} . Pansu and Gromov [Carnot-Carathéodory spaces seen from within, Birkhäuser, Basel, 1996] observed that any surface embedded in H \mathbb {H} has Hausdorff

Conformal maps of Carnot groups

Annales Academiae Scientiarum Fennicae Mathematica, 2015
If f is a conformal mapping defined on a connected open subset of a Carnot group G, then either f is the composition of a translation, a dilation and an isometry, or G is the nilpotent Iwasawa component of a real rank 1 simple Lie group S, and f arises from the action of S on G, viewed as an open subset of S/P, where P is a parabolic subgroup of G and ...

Current Landscape: Use of Supercritical CO2 in the Wood Industry

Advanced Energy and Sustainability Research, Volume 7, Issue 2, February 2026.
The application of supercritical carbon dioxide (scCO2) to successfully dewater as well as extract resin from wood is becoming increasingly popular due to its greener and less energy‐intensive approach. With world focus shifting to developing methods with greater efficiency while decreasing harm to the environment, scCO2 applications have begun to set ...

Factors impacting survival in individuals with Down syndrome‐associated Alzheimer's disease

Alzheimer's &Dementia, Volume 22, Issue 2, February 2026.
Abstract INTRODUCTION Adults with Down syndrome (DS) are at high risk for Alzheimer's disease (AD), the leading cause of death in this population. Survival in DS after AD diagnosis appears shorter than in sporadic AD; however, the factors influencing survival remain poorly understood.

Stability Theorems for H-Type Carnot Groups

The Journal of Geometric Analysis, 2023
We introduce the H-type deviation $δ({\mathbb G})$ of a step two Carnot group ${\mathbb G}$, which measures the deviation of the group from the class of Heisenberg-type groups. We show that $δ({\mathbb G})=0$ if and only if ${\mathbb G}$ carries a vertical metric which endows it with the structure of an H-type group. We compute the H-type deviation for

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
