—In this letter, a novel linear transmission strategy to design the linear precoding matrix (PM) at base station (BS) and the beamforming matrix (BM) at relay station (RS) for multiple-input multiple-output (MIMO) relaying broadcast channels with direct channel (DC) is proposed, in which a linear PM is designed at BS based on DC, and the RS utilizes the PM,(More)
— In this paper, we consider the capacity of a mul-ticast network, where a single-antenna secondary base station (SBS) utilizes the spectrum licensed to primary users (PUs) to broadcast the same information to multiple secondary users (SUs) with a single-antenna simultaneously, when the interference received by PUs is less than a predefined threshold. Based(More)
BACKGROUND The objective of this study was to prepare, characterize, and evaluate a folate-modified self-microemulsifying drug delivery system (FSMEDDS) with the aim to improve the solubility of curcumin and its delivery to the colon, facilitating endocytosis of FSMEDDS mediated by folate receptors on colon cancer cells. METHODS Ternary phase diagrams(More)
—Network coding is considered as a promising technique to improve diversity gain and network throughput in multi-source relay systems. This paper presents an opportunistic network coded cooperation scheme in wireless multi-unicast system with non-ideal source-relay channels. In the conventional network-coding-based cooperation schemes, the relay merges the(More)
In this paper, we consider a scenario where a secondary base station (SBS) with K antennas utilizes the licensed spectrum of a single primary user (PU) to send the same information to N secondary users (SUs). The SBS selects only one antenna out of the K antennas by using maximum signal power to leak interference power ratio strategy (SLIR). Using(More)
—In this paper, we analyze the asymptotic capacity in a spectrum sharing system where a secondary access point (SAP) restrictively utilizes the licensed spectrum of an active primary user (PU) to broadcast information to multiple secondary users (SUs) simultaneously, as long as the interference power inflicted on the PU is less than a predefined threshold.(More)
—This paper addresses bounds on the transmission capacities of two coexisting wireless networks (a primary and a secondary network), where each with multiple antennas shares the same spectrum and operates in the same geographic region. In the two coexisting network, the secondary (SR) network limits its interference to the primary (PR) network by carefully(More)
In this paper, we investigate the capacity of a multipoint-to-point cognitive radio network. In existing works, the asymptotic capacity is only obtained in the high peak power region at secondary transmitter (ST) or obtained without considering the interference from primary transmitter (PT) for easy analysis. Here, we analyze the asymptotic capacity by(More)
Oleracein E (OE), a tetrahydroisoquinoline possessing potent antioxidant activity, was first isolated from a traditional Chinese medicine, Portulaca oleraea L., and is hypothesized to be a neuroprotectant. In the present study, we evaluated the effects of racemic OE on rotenone-induced toxicity in Parkinson's disease (PD) cell and animal models.(More)
