The simple repetitive control system proposed by Yamada et al. is a type of servomechanism for the periodic reference input. That is, the simple repetitive control system follows the periodic reference input with small steady state error, even if a periodic disturbance or uncertainty exists in the plant. In addition, simple repetitive control systems make(More)
A set of k-principal points (Flury, 1990) of the distribution of a p-dimensional random vector X is defined as a set of k points in R p that minimizes the mean squared distance M SD ∥X − γ j ∥ 2 ]. A set of k-principal points provides an optimal k-point-approximation of the distribution and is a generalization of the mean E[X] from one point to k points.(More)
R-spondin (RSPO) gene fusions have recently been discovered in a subset of human colorectal cancer (CRC) in the U.S. population; however, whether the fusion is recurrent in CRC arising in patients from the other demographic areas and whether it is specific for CRC remain uncertain. In this study, we examined 75 primary CRCs and 121 primary lung cancers in(More)
Mitosis is the most conspicuous cell cycle phase and Shugoshin-like 1 (SGOL1) is a key protein in protecting sister chromatids from precocious separation during mitosis. We studied the role of SGOL1 and its splice variants in non-small cell lung cancer (NSCLC) using 82 frozen NSCLC tissue samples. SGOL1-B expression was prevalent in smokers, in cases with a(More)
The multi-period repetitive control system is a type of servomechanism for a periodic reference input. Even if a plant does not include time-delays, using multi-period repetitive controllers, the transfer function from the periodic reference input to the output and that from the disturbance to the output of the multi-period repetitive control system(More)
The simple repetitive control system proposed by Yamada et al. is a type of servomechanism for periodic reference input. Thus, the simple repetitive control system follows a periodic reference input with small steady-state error, even if there is periodic disturbance or uncertainty in the plant. In addition, simple repetitive control systems ensure that(More)
The simple multi-period repetitive control system proposed by Yamada and Takenaga is a type of servomechanism for the periodic reference input. That is, the simple multi-period repetitive control system follows the periodic reference input with small steady state error, even if a periodic disturbance or uncertainty exists in the plant. In addition, simple(More)
The modified repetitive control system is a type of servomechanism for periodic reference inputs. That is, the modified repetitive control system follows the periodic reference input with a small steady state error, even if a periodic disturbance or uncertainty exists in the plant. Using previously proposed modified repetitive controllers, even if the plant(More)
