OBJECTIVEdThere is now growing evidence that magnesium (Mg) deficiency is implicated in type 2 diabetes and its complications. However, it has not been fully elucidated whether hypomagnesemia is a predictor of end-stage renal disease (ESRD) in type 2 diabetic nephropathy. RESEARCH DESIGN AND METHODSdThis retrospective cohort study included 455 chronic(More)
This paper proposes a new algorithm for Simultaneous Localization and Mapping (SLAM) with omnidirectional stereo vision. In our approach, stereo matching is solved efficiently by using the estimated spatial information of the environment and robot motion. The use of two EKF (Extended Kalman Filter) estimators brings about a more reliable robot trajectory(More)
BACKGROUND In vitro studies have shown inhibitory effects of magnesium (Mg) on phosphate-induced calcification of vascular smooth muscle cells, raising the possibility that maintaining a high Mg level may be useful for reducing cardiovascular risks of patients with hyperphosphatemia. We examined how serum Mg levels affect the association between serum(More)
This study aimed to examine the relationships among electroencephalogram parameters as physiological indices, ballistic movement as an index of operation, and accuracy of task performance. Experiments were conducted using a "reaching" task, in which subjects touched the target appearing 300 pixels away from a start point in a vertical direction on a(More)
BACKGROUND The Agatston score, commonly used to quantify coronary artery calcification (CAC), is determined by the plaque area and density. Despite an excellent predictability of the Agatston score for cardiovascular events, the density of CAC has never been studied in patients with pre-dialysis chronic kidney disease (CKD). This study aimed to analyze the(More)
Source code is often reused in software development. Although developers can avoid re-implementing features in existing products, doing so may result in a large number of similar software products. To understand the commonalities and variabilities of similar products, comparing their source code is critical. However, a product may change its own directory(More)
SUMMARY This paper presents discussion about channel fluctuation on channel estimation in digital terrestrial television broadcasting. This channel estimation uses a two-dimensional (2D) filter. In our previous work, only a structure of a lattice is considered for generation of nonrectan-gular 2D filter. We investigate generation of nonrectangular 2D filter(More)
