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].

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

Algebraic prolongation and rigidity of Carnot groups
Monatshefte für Mathematik, 2009 We discuss the known results on rigidity of Carnot groups using Tanaka’s prolongation theory. We also apply Tanaka’s theory to study rigidity of an extended class of H-type groups which we call J-type groups. In particular we obtain a rigidity criterion giving rise to a rigid class of J-type groups which includes the H-type groups, and thus extends the

Energy Science &Engineering, EarlyView.ABSTRACT This study delves into exploring how pinhole size affects both the electrochemical efficiency and hydrogen leakage within proton exchange membrane fuel cells (PEMFCs). The researchers devised a comprehensive multiphysics field model for the PEMFC and employed the finite element method to simulate various pinhole diameters, evaluating their ...

Mass Spectrometry Reviews, EarlyView.ABSTRACT Complex organic mixtures are found in many areas of research, such as energy, environment, health, planetology, and cultural heritage, to name but a few. However, due to their complex chemical composition, which holds an extensive potential of information at the molecular level, their molecular characterization is challenging.

Rigidity of quasiconformal maps on Carnot groups [PDF]
Mathematical Proceedings of the Cambridge Philosophical Society, 2016 AbstractWe show that quasiconformal maps on many Carnot groups must be biLipschitz. In particular, this is the case for 2-step Carnot groups with reducible first layer. These results have implications for the rigidity of quasiisometries between negatively curved solvable Lie groups.

Application for Determining Repeatability and Reproducibility in an Honest Gauge R&R Study
Quality and Reliability Engineering International, EarlyView.ABSTRACT The analysis of variance (ANOVA) method and the range method are employed to conduct gauge repeatability and reproducibility studies. While the range method does not account for the statistical nature of the data, unlike the ANOVA method, it is, on the one hand, faster and, on the other hand, simpler to implement.

Autonomous Artificial Molecular Motors and Pumps
ChemSystemsChem, EarlyView.Autonomous energy consumption is the only way to introduce molecular motors into more sophisticated, larger systems, capable of life‐like behavior. We reviewed a selection of the most recent advances in the field molecular motors focusing on those capable of performing continuous and autonomous motion under constant experimental conditions, that is ...
