Summary of sinc numerical methods
Journal of Computational and Applied Mathematics, 2000 This article attempts to summarize the existing numerical methods based on Sinc approximation. Starting with a comparison of polynomial and Sinc approximation, basic formulas for the latter in the one-dimensional case are given. The author also covers the following: (i) Explicit spaces of analytic functions for one dimensional Sinc approximation, (ii ...

Demonstrating Vibrational Current Generation With a Self‐Assembled Bioelectret
Advanced Functional Materials, EarlyView.Vacuum‐deposited films of the plant‐derived molecule, Baicalein, form a self‐assembled bioelectret exhibiting spontaneous orientation polarization and a giant surface potential. The films induce alternating current during the vibration of a movable electrode without charging treatments. Hydrocarbon protection enhances the air stability of the Baicalein

Resonant Domain Wall Dynamics in a Three‐Dimensional Magnetic Nano Double Helix
Advanced Materials, EarlyView.3D magnetic nanostructures promise exciting possibilities for magnetization dynamics. However, experimental realizations remain scarce. In nanoprinted cobalt double helices, time‐resolved X‐ray microscopy reveals harmonic domain wall dynamics. Simulations identify the mode and additional higher‐frequency resonances, revealing a rich dynamic landscape ...

Space‐Time Coding Conformal Metasurfaces for Multifrequency Beam Steering and Shaping
Advanced Materials, EarlyView.Space‐time coding conformal metasurfaces enable dynamic wave control on curved surfaces by combining programmable spatial patterns with temporal modulation. This study shows that a single conformal aperture can independently manipulate multiple frequency components, achieving multifunctional beam shaping and steering, with implications for ...

Numerical solutions of one-dimensional non-linear parabolic equations using Sinc collocation method
Ain Shams Engineering Journal, 2015 We propose a numerical method for solving singularly perturbed one-dimensional non-linear parabolic problems. The equation converted to the nonlinear ordinary differential equation by discretization first in time then subsequently in each time level we ...

Advanced Science, EarlyView.Metastasis remains a major challenge in colorectal cancer. Using an in vivo shRNA screening system, this study identifies Homeobox D4 as a key metastasis suppressor. Reduced Homeobox D4 expression is associated with aggressive tumor features. Functional and mechanistic analyses show that it inhibits epithelial‐mesenchymal transition by repressing ...
