Introduction: Hadamard-encoded (H-encoded) fMRI [1] is a method that acquires a slab of multiple subslices with each RF excitation [2]. The subslices can then be extracted using temporal filtering, analogous to UNFOLD [3]. By setting the subslice width equal to that of a conventional fMRI scan, SNR is increased because of the larger slab thickness. However, since H-encoding uses complex data fo...
A lower bound on the sinc function is given. Application for the sequence {b(n)}(n=1)(∞) which related to Carleman inequality is given as well.
Prolate spheroidal wave functions have recently attracted much attention in applied harmonic analysis, signal processing, and mathematical physics. They are eigenvectors of the sinc-kernel operator Qc: time- band-limiting operator. The corresponding eigenvalues play a key role, aim this paper is to obtain precise non-asymptotic estimates with explicit constants related spectrum Qc. This issue r...
The sinc method is known as an ecient numerical method for solving ordinary or par-tial dierential equations but the system of dierential equations has not been solved by this method which is the focus of this paper. We have shown that the proposed version of sinc is able to solve sti system while Runge-kutta method can not able to solve. Moreover, Due to the great attention to mathematical mod...
It is a little over ten years sinc e Chidamber and Kemerer's obje ct-oriented (OO) metric suite which included the Lack of Cohesion Of Methods (LCOM) metric was rst proposed [9]. Despite considerable e ort both theoretically and empirically sinc e then, the softwar eengineering community is still no ne arer nding a generally ac cepte d de nition or me asure of OO cohesion. Y et,achieving highly...
BACKGROUND Pulmonary arterial hypertension (PAH) is a fatal disease characterized by impaired regulation of pulmonary artery vascular growth and remodeling. Aberrant expression of miR-17 has been shown to be involved in the pathogenesis of PAH, but its underlying molecular mechanism has not been elucidated. MATERIAL AND METHODS Mitofusin 2 (MFN2) expression was determined by qRT-PCR. The protei...
