Two-Weight Extrapolation on Lorentz Spaces

Journal of Function Spaces, 2015
We give several two-weight extrapolation theorems on Lorentz spaces which extend the results of Cruz-Uribe and Pérez (2000) and some applications for the singular integral operators, the potential type operators, and commutators.

Commutators of Singular Integral Operators and Lipschitz Functions on Amalgam Spaces

Journal of Function Spaces, 2020
In this paper, we obtain the boundedness of commutators generated by singular integral operators and Lipschitz functions on amalgam spaces and weighted amalgam spaces.

Unlocking the Power of Quercetin‐Encapsulated Mesoporous Bioactive Glass Nanoparticles: A Multifunctional Approach to Bone Regeneration

Advanced Engineering Materials, EarlyView.
Mesoporous bioactive glass nanoparticles (MBGNs) are investigated for bone regeneration given their remarkable structural and functional properties. MBGNs are functionalized with Mn and Cu and incorporated with quercetin, a natural flavonoid exhibiting antioxidant, anti‐inflammatory, and antimicrobial properties.

Hiperbolic singular integral operators

Revista Matemática Iberoamericana, 1995
We define a class of integral operators which are singular relative to the hyperbolic metric on simply connected domains of the plane. We study the necessary and sufficient conditions for such operators to be bounded on L^2 of the upper half plane relative to the hyperbolic metric.

A Comprehensive Review of Additive Manufacturing for Space Applications: Materials, Advances, Challenges, and Future Directions

Advanced Engineering Materials, EarlyView.
Additive manufacturing (AM) transforms space hardware by enabling lightweight, high‐performance, and on‐demand production. This review outlines AM processes—powder bed fusion (PBF), directed energy deposition (DED), binder jetting (BJ), sheet lamination (SL), and material extrusion (ME)—applied to propulsion, satellite structures, and thermal devices ...

Large Area, Cost‐Effective, and Ultra‐Fast Fabrication of Mini‐Coils Toward Noninvasive Magnetic Applications

Advanced Engineering Materials, EarlyView.
A simple, cleanroom‐free method produces flexible mini‐coils using automated blade cutting. The process is fast, low‐cost, and supports diverse materials. The coils show strong durability and performance under repeated bending. Demonstrated use in resistor‐inductor filters and magnetic nanoparticle control proves their adaptability.

Toward Maximum Utilization of Heavy Rare Earths in Sintered Nd–Fe–B Magnets by Grain Boundary Diffusion Source and Application Area Optimization

Advanced Engineering Materials, EarlyView.
In this work, the grain boundary diffusion process is optimized to maximize heavy rare earth utilization by strategic magnetic hardening of areas in the magnet such as corners or edges that are highly susceptible to demagnetization, as demonstrated by finite element magnetostatics simulation on an internal permanent magnet, synchronous traction motor ...
