Exploring Curvature Effects in Direct‐Written 3D Curved Hollow Magnetic Nanoshells

Advanced Functional Materials, EarlyView.
Fabricated by a hybrid FEBID/CVD method, 3D PtC/Co3Fe core–shell heterostructures with engineered curvature and shell thickness exhibit complex reversal modes with axially symmetric N'eel‐type domain walls. XMCD‐PEEM combined with full‐scale micromagnetic simulations reveal how curvature and thickness govern the domain wall energy landscape and shape ...

Quantifying Subsurface Weak in‐Plane Magnetization of Mixed Phase BiFeO3 by Scanning Nitrogen Vacancy Magnetometry

Advanced Functional Materials, EarlyView.
We use scanning nitrogen vacancy magnetometry to directly image the weak in‐plane magnetic moments in mixed phase BiFeO3 at the nanoscale and quantify the local magnetic moments to be 18.8±2.0 μB/nm2 in the rhombohedral‐like phase and 1.5±0.6 μB/nm2 in the well‐known non‐magnetic tetragonal‐like phase.

Least Squares Parameter Estimation for Sparse Functional Varying Coefficient Model [PDF]

Journal of Statistical Theory and Applications (JSTA), 2017
In the present paper, we study functional varying coefficient model in which both the response and the predictor are functions. We give estimates of the intercept and the slope functions in the case that the observations are sparse and noise-contaminated

On $n$-widths of classes of holomorphic functions with reproducing kernels

Illinois Journal of Mathematics, 1994
For a subset \(A\) of a Banach space \(X\), the Kolmogorov and Gel'fand \(n\)-widths are defined by \(d_ n (A,X) = \inf_{X_ n} \sup_{x \in A} \inf_{y \in X_ n}\) \(\| x - y \|\) and \(d^ n(A,X) = \inf_{Y_ n} \sup_{x \in A \cap Y_ n} \| x \|\), respectively, where \(X_ n\) runs over all \(n\)-dimensional subspaces and \(Y_ n\) over all closed subspaces ...

Reproducing kernel method for a class of weakly singular Fredholm integral equations

Journal of Taibah University for Science, 2018
Numerical methods for solving integral equations have been the focus of much research, including reproducing kernel methods. We present a new algorithm to solve weakly singular Fredholm integral equations (WSFIEs). The advantage of this method is that it

A Data Driven Review of In Vitro Electrical and Mechanical Stimulation for Post‐Acute Phase Wound Healing

Advanced Healthcare Materials, EarlyView.
This review examines how in vitro electrical and mechanical stimulation modulates wound healing in fibroblasts and keratinocytes. Analyzing over 560 experimental data points, we relate stimulation parameters to proliferation and migration outcomes, evaluate platform designs, and highlight the need for multi‐parameter optimization to advance targeted ...

Numerical technique for solving physical models using reproducing kernel Hilbert space method with purely integral conditions

Boundary Value Problems
In this work, we investigate the Klein–Gordon equation, a physical problem, using the reproducing kernel Hilbert space method (RKHSM). The analytical solution is expressed as a series within the reproducing kernel Hilbert space (RKHS).

Reproducing Kernel Hilbert spaces of analytic functions

This thesis focuses on the study of reproducing kernel Hilbert spaces (RKHS), which play a fundamental role in complex analysis as well as in other fields such as statistics and machine learning. It presents the general theory of RKHS, including key results that characterize these spaces and their properties, such as the representation of kernels in ...
