Solution of a Volterra integral equation by the Sinc-collocation method

Journal of Computational and Applied Mathematics, 2007
The authors investigate the following problems: (1) a collocation procedure for a linear Volterra integral equation of the second kind and (2) its approximate solutions using the sinc basis functions based on the conformal maps of analytic functions.

Ventilation Imaging of the Lung at 0.55T With Continuous Slice Cycling

Magnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose To propose and evaluate a novel method for pulmonary ventilation imaging, offering considerably improved SNR. Methods A continuous slice cycling (CSC) acquisition scheme is proposed to exclusively capture signal modulations from respiratory motion with increased SNR.

Sinc-Approximations of Fractional Operators: A Computing Approach

Mathematics, 2015
We discuss a new approach to represent fractional operators by Sinc approximation using convolution integrals. A spin off of the convolution representation is an effective inverse Laplace transform.

A Modified Balanced Steady State Free Precession Sequence for Overhauser Magnetic Resonance Imaging

Magnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose Low‐ and ultralow‐field magnetic resonance imaging (ULF MRI) have inherently low signal‐to‐noise ratio (SNR) by design. Overhauser dynamic nuclear polarization (ODNP) stands out as an effective solution for continuous signal enhancement.

Curcumin Alleviates the Osteogenesis Inhibition and the Aging Process in BMSCs Induced by Iron Overload Through Activating the NRF2/GPX4 Pathway

Phytotherapy Research, EarlyView.
Under iron overload conditions, curcumin inhibits cellular senescence and promotes osteogenic differentiation by activating the NRF2/GPX4 signaling pathway in bone marrow mesenchymal stem cells (BMSCs), thereby preventing the onset of osteoporosis. ABSTRACT Dysregulated proliferation and differentiation of bone marrow mesenchymal stem cells (BMSCs ...

A kind of adaptive variable stepsize embedded Runge–Kutta pairs coupled with the Sinc collocation method for solving the KdV equation

Results in Applied Mathematics
For solving the KdV equation, a novel numerical method with high order accuracy in both space and time is proposed. In the spatial direction, Sinc collocation method, which has the property of exponential convergence, is adopted.

Convergence of the Sinc Overlapping Domain Decomposition Method

, 1997
The sinc-collocation overlapping method is developed for two-point boundary-value problems for second-order ordinary differential equations. The discrete system is formulated and the bordering algorithm used for the solution of this system is described ...

Deciphering diverse cell‐death patterns to predict the prognosis and potential therapy target of hepatocellular carcinoma patients

VIEW, EarlyView.
Abstract Ninety percent of all primary liver malignancies are hepatocellular carcinomas (HCC), making liver cancer the third most common cause of cancer‐associated mortality. Different patterns of programmed cell death (PCD) are crucial for the survival of tumors, and they might serve as a prognostic marker for HCC.
