C-kit positive (c-kit(+)) cells are usual tissue-specific stem cells. However, in postnatal testis, undifferentiated spermatogonial stem cells (SSCs) are c-kit negative (c-kit(-)) and activation of c-kit represents the start of SSC differentiation, leaving an intriguing question whether other c-kit(+) cells exist and participate in the postnatal development(More)
Albuminuria contributes to the progression of tubulointerstitial fibrosis. Although it has been demonstrated that ongoing albuminuria leads to tubular injury manifested by the overexpression of numerous proinflammatory cytokines, the mechanism remains largely unknown. In this study, we found that the inflammasome activation which has been recognized as one(More)
In subband adaptive signal processing, the performance of system is seriously disturbed by the aliasing in-band introduced by decimator, which comes from the none-ideal of analysis filter banks. In this paper a novel method called DFTSD (Discrete Fourier Transform Subband Decomposition) is proposed for signal decomposition in frequency domain, in which(More)
— A heterogeneous-aware cooperative MIMO transmission scheme (HAMS) is proposed to optimize the network lifetime and save energy for energy heterogeneous wireless sensor networks (WSN). This scheme extends the traditional low-energy adaptive clustering hierarchy (LEACH) protocol to enable the cooperative MIMO transmission between the sink and clusters.(More)
This paper develops a discrete operation optimization model for combined heat and powers (CHPs) in deregulated energy markets to maximize owners' profits, where energy price forecasting is included. First, a single input and multi-output (SIMO) model for typical CHPs is established, considering the varying ratio between heat and electricity outputs at(More)
In array signal processing, the performance of parameter estimation is effected by the unknown nonuniform perturbations on the sensors of receiver array. In this work, the problem of passive localization of near-field sources with partly calibrated subarray-based array is studied. Rank reduction (RARE) is extended to its 2-Dimensional version to solve this(More)
Network-connected combined heat and powers (CHPs), owned by a community, can export surplus heat and electricity to corresponding heat and electric networks after community loads are satisfied. This paper proposes a new optimization model for network-connected CHP operation. Both CHPs' overall efficiency and heat to electricity ratio (HTER) are assumed to(More)
