Assessment of Tumor Cell Invasion and Radiotherapy Response in Experimental Glioma by Magnetic Resonance Elastography

open access: yesJournal 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.

Regularity Criterion for Weak Solutions to the Navier-Stokes Equations in Terms of the Gradient of the Pressure

open access: yesJournal of Inequalities and Applications, 2008
We prove a regularity criterion ∇π∈L2/3(0,T;BMO) for weak solutions to the Navier-Stokes equations in three-space dimensions. This improves the available result with L2/3(0,T;L∞).

The Weighted Lp and BMO Estimates for Fractional Hausdorff Operators on the Heisenberg Group

open access: yesJournal of Function Spaces, 2020
In the setting of Heisenberg group, we characterize those functions Φ, for which the fractional Hausdorff operators TΦ,β and Hausdorff operators TΦ, T˜Φ are bounded on Lp spaces with power weights, BMO space, and Hardy spaces, respectively.

Fractional Order PID Controller Based‐Neural Network Algorithm for LFC in Multi‐Area Power Systems

open access: yesEngineering 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 ...
