To support interference-free quasi-synchronous code-division multiple-access (QS-CDMA) communication with low spectral density profile in a cognitive radio (CR) network, it is desirable to design a set of CDMA spreading sequences with zero-correlation zone (ZCZ) property. However, traditional ZCZ sequences (which assume the availability of the entire(More)
The performance of adaptive routing strongly depends on its degree of adaptive ness in Network-on-chip (NoC). It is observed that there exists adaptive imbalance between even and odd columns in the well-known odd-even (OE) model. In this paper, we present an improved OE model, called symmetric OE model (SOE), which provides higher level of adaptive ness and(More)
Although the OFDM/offset QAM (OFDM/OQAM) systems is robust against the double selective fading channel, it unfortunately is still sensitive to timing synchronization errors and carrier-frequency offsets (CFOs). To solve this problem of OFDM/OQAM systems, in this paper, a joint symbol timing and CFO estimation algorithm is developed, which employs a sliding(More)
MicroRNAs can coordinately repress multiple target genes and interfere with the biological functions of the cell, such as proliferation and apoptosis. In the present study, we report that miR-200b was downregulated in malignant glioma cell lines and specimens. Overexpression of miR-200b suppressed the proliferation and colony formation of glioma cells. An(More)
Abstract Nateglinide, a D-phenylalanine derivative, belongs to a new group of insulinotropic agents with rapid onset and short duration of action. These agents have been developed to reduce the risk of hypoglycaemia associated with pharmacological control and to decrease the likelihood of pancreatic beta-cell exhaustion. Nateglinide mediates the release of(More)
This paper presents a cluster-based transform domain communication system (TDCS) to improve spectrum efficiency. Unlike the utilities of clusters in orthogonal frequency division multiplex (OFDM) systems, the cluster-based TDCS framework divides entire unoccupied spectrum bins into L clusters, where each one represents a data steam independently, to achieve(More)
