AIMS Mathematics, 2023 In this paper, we establish some boundedness for commutators generated by the singular integral operator satisfying a variant of Hörmander's condition and a weighted BMO function on weighted Hardy spaces and weighted Herz spaces.

Lectures on Nehari's Theorem on the Polydisk [PDF]
, 2006 We give a leisurely proof of a result of Ferguson--Lacey (math.CA/0104144) and Lacey--Terwelleger (math.CA/0601192) on a Nehari theorem for "little" Hankel operators on a polydisk.

Journal of Magnetic Resonance Imaging, Volume 61, Issue 3, Page 1203-1218, March 2025.Background Gliomas are highly invasive brain neoplasms. MRI is the most important tool to diagnose and monitor glioma but has shortcomings. In particular, the assessment of tumor cell invasion is insufficient. This is a clinical dilemma, as recurrence can arise from MRI‐occult glioma cell invasion.

Optical study of the vibrational and dielectric properties of BiMnO3
, 2015 BiMnO3 (BMO), ferromagnetic (FM) below Tc = 100 K, was believed to be also ferroelectric (FE) due to a non-centro-symmetric C2 structure, until diffraction data indicated that its space group is the centro-symmetric C2/c.

Duality theorems for coinvariant subspaces of $H^1$
, 2014 Let $\theta$ be an inner function satisfying the connected level set condition of B. Cohn, and let $K^{1}_{\theta}$ be the shift-coinvariant subspace of the Hardy space $H^1$ generated by $\theta$.

Pointwise multipliers of weighted BMO spaces [PDF]
Proceedings of the American Mathematical Society, 1989 An atomic decomposition is obtained for dyadic weighted HI spaces with dual weighted dyadic BMO. All multipliers of dyadic weighted BMO and weighted BMO are characterized. As an application, the behavior of "logarithms" of BMO matrices are analyzed for weighted norm inequalities. 1. BMO MULTIPLIERS On R, let t = {intervals of the form [t + k2n, t + (k +

Boundedness of Commutators of High-Dimensional Hausdorff Operators
Journal of Function Spaces and Applications, 2012 We prove the boundedness of commutators of high-dimensional Hausdorff operators 𝐻Φ,𝑏 on Lebesgue space with central BMO function or Lipschitz function. Furthermore, the boundedness on Herz spaces and Morrey-Herz spaces is also obtained.

Fractional Order PID Controller Based‐Neural Network Algorithm for LFC in Multi‐Area Power Systems
Engineering Reports, Volume 7, Issue 2, February 2025.Motivated by artificial neural networks, this paper develops the NNA to optimize a Fractional‐Order PID controller for LFC in multi‐area interconnected power systems. It improves frequency regulating capabilities and reduces overshoots/undershoots. It achieves a 27.66%–93.78% improvement in Integral of Time Absolute Error compared to other techniques ...
