A highly accurate numerical method for solving boundary value problem of generalized Bagley‐Torvik equation

Mathematical Methods in the Applied Sciences, EarlyView.
A highly accurate numerical method is given for the solution of boundary value problem of generalized Bagley‐Torvik (BgT) equation with Caputo derivative of order 0<β<2$$ 0<\beta <2 $$ by using the collocation‐shooting method (C‐SM). The collocation solution is constructed in the space Sm+1(1)$$ {S}_{m+1}^{(1)} $$ as piecewise polynomials of degree at ...

Fundamental Solutions and Green's Functions for Certain Elliptic Differential Operators From a Pseudodifferential Algebra

Mathematical Methods in the Applied Sciences, EarlyView.
ABSTRACT We have studied possible applications of a particular pseudodifferential algebra in singular analysis for the construction of fundamental solutions and Green's functions of a certain class of elliptic partial differential operators. The pseudodifferential algebra considered in the present work, comprises degenerate partial differential ...

Real‐time cardiac cine MRI: A comparison of a diffusion probabilistic model with alternative state‐of‐the‐art image reconstruction techniques for undersampled spiral acquisitions

Magnetic Resonance in Medicine, EarlyView.
Abstract Purpose Electrocardiogram (ECG)‐gated cine imaging in breath‐hold enables high‐quality diagnostics in most patients but can be compromised by arrhythmia and inability to hold breath. Real‐time cardiac MRI offers faster and robust exams without these limitations.

Modeling the effect of in‐plane magnetic field gradients on asymmetric spin‐echo images with echo‐planar imaging readout

Magnetic Resonance in Medicine, EarlyView.
Abstract Purpose To describe the impact of macroscopic magnetic field gradients (MFGs) in the phase‐encoding direction on MR images acquired with an asymmetric spin echo (ASE) sequence with echo‐planar imaging (EPI) readout. Methods In EPI, the center of k‐space is read out at a shifted time point in the presence of phase‐encoding direction MFGs.

Seismic Bearing Capacity of Shallow Foundations in Anisotropic Non‐Homogeneous Soils Under Torsional Waves and Parameter Uncertainty

International Journal for Numerical and Analytical Methods in Geomechanics, EarlyView.
ABSTRACT The purpose of the present paper is to investigate the effects of the torsional wave propagation and the soil‐earthquake parameter uncertainties on the seismic bearing capacity of shallow foundations in anisotropic non‐homogeneous media.
