Chiral Phase Change Nanomaterials
Advanced Functional Materials, EarlyView.This work demonstrates reversible, non‐volatile phase transitions in chiral Ge2${\rm Ge}_2$Sb2${\rm Sb}_2$Te5${\rm Te}_5$ (GST) nanohelices for high‐speed optical modulation of chirality and dynamic control of the state of polarization (SOP). The chiral nanostructures are fabricated using a highly directional, wafer‐scale physical vapor deposition ...

A theorem for Fourier coefficients of a function of class Lp
International Journal of Mathematics and Mathematical Sciences, 1990 This paper deals with the Fourier coefficients of a function of class Lp. We give a necessary and sufficient condition for function to be of class Lp for p greater than one.

Microfabricated Anisotropic Myobundles for the Scalable Production of Cardiac Tissue Grafts
Advanced Functional Materials, EarlyView.Controlling the anisotropy of cardiac tissue remains an outstanding challenge in the field of cardiac tissue engineering. Here, we introduce an approach to generate anisotropic cardiac myobundles using cell‐adhesive, synthetic, electrospun fibers and stem cell‐derived cardiac fibroblasts.

HEART ABNORMALITY CLASSIFICATIONS USING FOURIER TRANSFORMS METHOD AND NEURAL NETWORKS
Indonesian Journal of Tropical and Infectious Disease, 2015 Health problems with cardiovascular system disorder are still ranked high globally. One way to detect abnormalities in the cardiovascular system especially in the heart is through the electrocardiogram (ECG) reading.

Computing coefficients of Fourier series
Informatica, 1997 Some approaches to the numerical evaluation of Fourier coefficients are outlined. Numerical quadrature formulas of Filon type are developed using higher-order polynomial approximations, in particular third- and fifth-order Hermite interpolants. Adaptive methods of implementation are described.

Asymptotic estimates for the generalized Fourier coefficients
, 1984 Explicit forms for the orthonormal polynomials with respect to a given weight function on the interval [−1, 1] usually are difficult to construct. In this paper we give asymptotic estimates for the generalized Fourier coefficients of functions expanded ...

A Dual‐Functional Electrolyte Additive for Highly Reversible Zinc‐Ion Batteries
Advanced Functional Materials, EarlyView.This study introduces tetrabutylammonium bromide (TBAB) as a dual‐function additive for aqueous zinc‐ion batteries. TBAB disrupts the hydrogen‐bond network of water while TBA+ adsorbs on Zn to improve interfacial wettability and regulate Zn2+ flux, resulting in suppressed dendrite growth and parasitic reactions. This synergy extended the lifespan of Zn|
