Efficient Multifunctional Response and Polarization Switching in BiFeO3–PbZr0.58Ti0.42O3–MnFe2O4‐Based Triphasic Composites for Advanced Pulsating Applications

open access: yesAdvanced Engineering Materials, EarlyView.
Triphasic BiFeO3–PbZr0.58Ti0.42O3–MnFe2O4 composites exhibit enhanced ferroelectric and magnetic behavior, achieving 70.76% energy‐storage efficiency and improved polarization switching. The coupling between ferroelectric and magnetic phases enables multifunctional performance, making these composites promising candidates for next‐generation energy ...

Clifford algebra-valued orthogonal polynomials in the open unit ball of Euclidean space

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 2004
A new method for constructing Clifford algebra-valued orthogonal polynomials in the open unit ball of Euclidean space is presented. In earlier research, we only dealt with scalar-valued weight functions.

The mathematical approach for proximity analysis for 3D GIS [PDF]

open access: yes, 2008
Next generation of GIS software would highly depend on 3D analysis in solving geographic problems. 3D analysis is a very important component for GIS as it defines as decision making tools for geographic features.

Thermally Induced Gelling Systems Based on Patchy Polymeric Micelles

open access: yesAdvanced Functional Materials, Volume 35, Issue 12, March 18, 2025.
A novel strategy to design thermally induced gelling systems with tunable material properties is reported. Polymeric mixed‐shell micelles displaying multiple thermosensitive patchy domains formed hydrogels by assembling into well‐entangled worm‐like network structures upon heating to body temperature. The patchy micelle design significantly affects the

On Concrete Spectral Properties of a Twisted Laplacian Associated with a Central Extension of the Real Heisenberg Group

open access: yesAdvances in Mathematical Physics, 2017
We consider the special magnetic Laplacian given by Δν,μ=4∑j=1n∂2/∂zj∂zj¯+2iνE+E¯+n+2μE-E¯-ν2+μ2z2. We show that Δν,μ is connected to the sub-Laplacian of a group of Heisenberg type given by C ×ω Cn realized as a central extension of the real Heisenberg ...

Optimal Gabor frame bounds for separable lattices and estimates for Jacobi theta functions

open access: yes, 2016
We study sharp frame bounds of Gabor frames with the standard Gaussian window and prove that the square lattice optimizes both the lower and the upper frame bound among all rectangular lattices.
