Journal of Magnetic Resonance Imaging, EarlyView.ABSTRACT Background The demand for cardiac MRI is increasing with the growing burden of cardiovascular disease. However, conventional protocols require sequential acquisitions for multi‐breath‐hold 2D cine and 3D MR angiography (MRA), which is time‐consuming.

Cartesian Grid Method for Gas Kinetic Scheme
, 2015 A Cartesian grid method combined with a simplified gas kinetic scheme is presented for subsonic and supersonic viscous flow simulation on complex geometries. Under the Cartesian mesh, the computational grid points are classified into four different categories, the fluid point, the solid point, the drop point, and the interpolation point. The boundaries

Anisotropic Cartesian grid adaptation
Anisotropic Cartesian grid adaptation航空宇宙技術研究所 17-19 Jan. 2000 東京 日本 National Aerospace Laboratory 17-19 Jan. 2000 Tokyo Japan 流れ特性の解明に必要なセル全体の数を減らし、現行のデカルト格子の適用効率を改善するため、3次元におけるデカルト格子を使い格子適用法を改善してきた。この方法ではセルのアスペクト比が任意の値を取る事ができるように格子を粗くしたり、細かくする事ができる。この方法を用いて円筒の周りの超音速流とONERA M6翼の周りの遷音速流に対する流れの計算を示した。これらは実験と良く一致した。この方法ではセルの数は等方性の方法より67分の1と少ないセルの数であった ...

Nonlocal active sound control for composite regions
Mathematical Methods in the Applied Sciences, EarlyView.In the active sound control problem, additional sound sources, known as control sources, are implemented at the perimeter of a protected domain. The control sources can generate secondary sound inside the shielded domain, which attenuates incoming noise. This leads to an inverse source problem.

A general lower bound for the domination number of cylindrical graphs
, 2018 In this paper we present a lower bound for the domination number of the Cartesian product of a path and a cycle, that is tight if the length of the cycle is a multiple of five.

Dynamic Mode Decomposition (DMD) for Low‐Latency Real‐Time Cardiac MRI
Magnetic Resonance in Medicine, EarlyView.ABSTRACT Purpose To demonstrate dynamic mode decomposition (DMD) for high spatiotemporal low‐latency online reconstruction in 2D real‐time cardiac MRI. Methods DMD was applied to 2D spiral balanced steady state free precession (bSSFP) real‐time adult and fetal cardiac MRI at 0.55 T, with data from 10 healthy adult volunteers (3F/7M; age: 21–49; BMI: 20–
