—A massive multiuser multiple-input–multiple-output (MU-MIMO) system working at millimeter-wave frequencies is a new concept that has appeared in recent years. In such systems, the sparsity of the beamspace channel matrix makes the channel rank reduction and limited feedback realizable. Based on these preferable features, this paper introduces two kinds of(More)
The testicular yolk sac tumor (TYST) is the most common neoplasm originated from germ cells differentiated abnormally, a major part of pediatric malignant testicular tumors. The present study aimed at developing and validating the in vitro and vivo models of TYST and evaluating the sensitivity of TYST to treatments, by cloning human TYST cells and(More)
This paper presents a general expression for the marginal distributions of the ordered eigenvalues of certain important random matrices. The expression, given in terms of matrix determinants, is compacter in representation and more efficient in computational complexity than existing results in the literature. As an illustrative application of the new(More)
