Triangular maximal operators on locally finite trees
Mathematika, Volume 70, Issue 3, July 2024.Abstract We introduce the centred and the uncentred triangular maximal operators T$\mathcal {T}$ and U$\mathcal {U}$, respectively, on any locally finite tree in which each vertex has at least three neighbours. We prove that both T$\mathcal {T}$ and U$\mathcal {U}$ are bounded on Lp$L^p$ for every p$p$ in (1,∞]$(1,\infty]$, that T$\mathcal {T}$ is also

On certain estimates for Marcinkiewicz integrals and extrapolation
Collectanea mathematica, 2009 Let \(\mathbb R^n\), \(n\geq2\), be the \(n\)-dimensional Euclidean space and \(S^{n-1}\) be the unit sphere in \(\mathbb R^n\) with area element \(d\sigma(x')\) on \(S^{n-1}\). Let \(\Omega(x)|x|^{-n}\) be a homogeneous function of degree \(-n\) on \(\mathbb R^n\), with \(\Omega\in L^1(S^{n-1})\) and \(\int_{S^{n-1}}\Omega(x')\,d\sigma(x')=0\), where \

Journal of Comparative Neurology, Volume 532, Issue 6, June 2024.Graphical Abstract: We used single‐cell transcriptomics to explore cell type and neuronal class diversity, and in situ hybridization chain reaction to view expression in the brain of the nudibranch mollusc, Berghia stephanieae. Gene markers for nudibranch neurons and glia were found.

L p Estimates for Marcinkiewicz integral operators and extrapolation [PDF]
Journal of Inequalities and Applications, 2014 In this article, we establish estimates for parametric Marcinkiewicz integral operators with rough kernels. These estimates and extrapolation arguments improve and extend some known results on Marcinkiewicz integrals. MSC:40B20, 40B15, 40B25.

Journal of Applied Econometrics, Volume 39, Issue 4, Page 620-639, June/July 2024.Summary This paper introduces a novel panel approach to structural vector autoregressive analysis. For identification, we impose independence of structural innovations at the pooled level. We demonstrate robustness of the method under cross‐sectional correlation and heterogeneity through simulation experiments.
