Application of Variable Step‐Size Hybrid Methods for Solving Third‐Order Lane‐Emden Equations
Mathematical Methods in the Applied Sciences, EarlyView.ABSTRACT This manuscript introduces a pair of variable step‐size hybrid methods (PVSHM) to efficiently solve third‐order initial value problems of Lane‐Emden‐type equations (LETE). These equations are extensively used across various disciplines, including chemical engineering, fluid mechanics, physics, and astrophysics, to model a wide range of real ...

Attractors for an Energy‐Damped Viscoelastic Plate Equation
Mathematical Methods in the Applied Sciences, EarlyView.ABSTRACT In this paper, we consider a class of non‐autonomous beam/plate equations with an integro‐differential damping given by a possibly degenerate memory and an energy damping given by a nonlocal ε$$ \varepsilon $$‐perturbed coefficient. For each ε>0$$ \varepsilon >0 $$, we show that the dynamical system generated by the weak solutions of the ...

Applications of Fast Iterative Filtering in NMR Spectroscopy: Baseline Correction
Magnetic Resonance in Chemistry, EarlyView.Fast iterative filtering is a signal decomposition technique related to empirical mode decomposition. When decomposing NMR data into intrinsic mode functions, FIF effectively partitions broad baseline components from narrow peaks components, even in heavily distorted spectra, for instance, those of paramagnetic compounds.

In vivo evaluation of population‐specific inversion pulses in parallel transmission
Magnetic Resonance in Medicine, EarlyView.Abstract Purpose The aim of the study was to conduct in vivo evaluation of population‐specific pulses in the context of the MP2RAGE sequence for brain imaging at 7T. Methods Five clusters were identified in a cohort of 39 volunteers. One cluster centered around the average head shape and position, whereas four others were located toward the extremes of
