Image Restoration Models Based on Dyadic Hardy Space and Dyadic Bounded Mean Oscillation Space

IEEE Access, 2019
Texture is widely existed in various images and plays an important role in many area such as medical image diagnosis, remote sensing, etc. However, the image in texture regions is tend to be deteriorated during restoration process.

Function spaces for decoupling

Journal of the London Mathematical Society, Volume 113, Issue 4, April 2026.
Abstract We introduce new function spaces LW,sq,p(Rn)$\mathcal {L}_{W,s}^{q,p}(\mathbb {R}^{n})$ that yield a natural reformulation of the ℓqLp$\ell ^{q}L^{p}$ decoupling inequalities for the sphere and the light cone. These spaces are invariant under the Euclidean half‐wave propagators, but not under all Fourier integral operators unless p=q$p=q$, in ...

Interpolation inequalities between Lorentz space and BMO: the endpoint case (L^{1,infinity}, BMO)

Electronic Journal of Differential Equations, 2019
We prove interpolation inequalities by means of the Lorentz norm, BMO norm, and the fractional Sobolev norm. In particular, we obtain an interpolation inequality for $(L^{1,\infty}, BMO)$, that we call the endpoint case.

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

Journal 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∞).

Effects of vagal nerve stimulation on pain frequency and intensity in chronic migraine in adults: A randomized controlled trial

Physiological Reports, Volume 14, Issue 7, April 2026.
Abstract To determine the effects of noninvasive vagal nerve stimulation (nVNS) on the frequency, intensity, impact, and quality of life in individuals with chronic migraine. The randomized controlled trial (RCT) was conducted over 128 participants, randomly assigned to either the experimental or control group.

Emergent Freestanding Complex Oxide Membranes for Multifunctional Applications

Advanced Materials, Volume 38, Issue 16, 17 March 2026.
This review surveys freestanding oxide membranes and covers fabrication and three pathways for studies and devices: strain‐free and strained membranes, and van der Waals‐integrated heterostructures. We show how coupled oxide responses map onto these routes and cross‐couple to expand behaviors.

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

Journal 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.
