Riesz potential and its commutators on Orlicz spaces
Journal of Inequalities and Applications, 2017 In the present paper, we shall give necessary and sufficient conditions for the strong and weak boundedness of the Riesz potential operator I α $I_{\alpha}$ on Orlicz spaces. Cianchi (J. Lond. Math. Soc.

Operator-valued dyadic BMO spaces
, 2008 We consider BMO spaces of operator-valued functions, among them the space of operator-valued functions $B$ which define a bounded paraproduct on $L^2(H)$. We obtain several equivalent formulations of $\| _B\|$ in terms of the norm of the "sweep" function of $B$ or of averages of the norms of martingales transforms of $B$ in related spaces. Furthermore,

Tunable Plasmons in Photoelectrochemical Water Splitting: An Overview
Advanced Sustainable Systems, Volume 10, Issue 1, January 2026.Plasmonic materials based on non‐noble metals, including Al, Cu, metal oxides, and chalcogenides, enhance photoelectrochemical water splitting by improving solar light harvesting and catalytic activity. Their spectrally tunable localized surface plasmon resonance, low cost, and elemental abundance make them viable alternatives to noble metals ...

BMO-Boundedness of Maximal Operators and g-Functions Associated with Laguerre Expansions
Journal of Function Spaces and Applications, 2012 Let {𝜑𝛼𝑛}𝑛∈ℕ be the Laguerre functions of Hermite type with index 𝛼. These are eigenfunctions of the Laguerre differential operator 𝐿𝛼=1/2(−𝑑2/𝑑𝑦2+𝑦2+1/𝑦2(𝛼2−1/4)). In this paper, we investigate the boundedness of the Hardy-Littlewood maximal function,

Agronomy Journal, Volume 118, Issue 1, January/February 2026.Abstract Biological indicators, including particulate organic matter C (POMC) and N (POMN), potentially mineralizable N (PMN), fluorescein diacetate (FDA) hydrolysis, and permanganate oxidizable C (POXC), may prove useful soil health indicators if they can link management to soil productivity.

Two weight estimates for a class of (p, q) type sublinear operators and their commutators
Open Mathematics, 2019 In the present paper, the authors investigate the two weight, weak-(p, q) type norm inequalities for a class of sublinear operators 𝓣γ and their commutators [b, 𝓣γ] on weighted Morrey and Amalgam spaces.

Evaluation of Precipitation Observations Across Ecuador
Atmospheric Science Letters, Volume 27, Issue 1, January 2026.This study aims to evaluate the performance of three precipitation products—ERA5 reanalysis, IMERG (Integrated Multi‐satellite Retrievals for GPM), and MSWEP (Multi‐Source Weighted‐Ensemble Precipitation)—across Ecuador's diverse climates and terrains.

Journal of Inequalities and Applications, 2019 Our goal is to obtain the John–Nirenberg inequality for ball Banach function spaces X, provided that the Hardy–Littlewood maximal operator M is bounded on the associate space X′ $X'$ by using the extrapolation.

Local hardy and BMO spaces on non-homogeneous spaces [PDF]
Journal of the Australian Mathematical Society, 2005 AbstractLet µ be Radon measure on Rd which may be non doubling. The only condition that µ must satisfy is the size condition µ(B(x, r)) ≤ Crn for some fixed n є (0, d). Recently, Tolsa introduced the spaces RBMO(µ) and Hatb1.∞ (µ), which, in some ways, play the role of the classical spaces BMO and H1 in case u is a doubling measure.

Pregnancy, Volume 2, Issue 1, January 2026.Abstract Background Pregnant and postpartum patients are at risk of infectious sacroiliitis due to the increased demand on the sacroiliac joint as well as the changes in the pelvis during pregnancy and delivery. Case We present the case of a 34‐year‐old woman who developed severe back pain following an uncomplicated vaginal delivery and was ultimately ...
