Background Because tumorigenesis depends on a variety of oncogenes, symphyseal study of combined genes may lead to more significant knowledge about tumorigenesis and progression. Combined deficiency of p21 and p27 proteins in mice is linked to more aggressive spontaneous tumorigenesis. We investigated the effect of the transfected p21Waf1-p27Kip1 gene on centrosome duplication, cell proliferation,...
The ability of immune system to react specifically against tumors inspirited the study of triple negative breast cancer (TNBC) immunotherapies. Sixty spontaneous breast cancer TA2 mice were randomly divided into three groups: GM-CSF group, with therapy of granulocyte–macrophage colony-stimulating factor (GM-CSF) combined with breast cancer stem cells associated antigens and cytosine–phosphorothioate–guanine...
The orthogonal random beamforming is a practical scheme to increase the throughput of the MIMO system significantly. But the fairness allover the subscribers is the weak point. In this paper, the proportional fair scheduling scheme is introduced to the ORBF scheme for the multi-user MIMO systems and two adaptive proportional fair scheduling schemes are proposed to increase the throughput of the subscribers...
In cooperative OFDM networks, ordered subcarrier pairing (OSP) at the relay has been shown to improve the average end-to-end capacity evidently. In this paper, the statistical performance evaluations are provide for two-hop OFDM relay link with both amplify-and-forward (AF) and decode-and-forward (DF) protocol. First, closed-form expressions are derived for the probability density function (PDF) of...
In this paper we present two strategy to maximize user's throughput in Cooperative MU-OFDM network while considering fairness of users. Our strategy is proposed to improve throughput and fairness of users only with limited feedback. With perfect instantaneous channel state information(CSI) at receiver, the resource allocating strategy not only decided in base station, but also decided in users of...
Subcarrier mapping (SCM) is an efficient way to evidently improve the average end-to-end capacity in cooperative OFDM networks. However perfect channel knowledge is required, which leads to large feedback amount of channel state information (CSI). In this paper, the uplink scenario of multi-relay OFDM cooperative networks with subcarrier mapping scheme is considered. An opportunistic relaying strategy...
Cooperative communication is an efficient method to combat wireless channel fading and to increase system throughput in future board communication. Through physical layer networking coding(PNC)modulation, two-way relaying has been shown to improve the network capacity significantly. However for power-constraints application, the performance of two-way relaying is actually inferior to one-way relaying...
A space-time coding scheme based on interleave division multiplexing (EDM) is investigated over an orthogonal frequency division multiplexing (OFDM) link that employs multiple transmit antennas. The performance of an iterative receiver structure for the proposed scheme over a quasi-static channel is evaluated via simulation, and its advantages are shown by comparison to other space-time schemes in...
Cooperative OFDM transmission is an efficient solution to combat wireless channel fading and to increase system throughput in future board communication. In this paper, we consider the uplink scenario of a cellular cooperative OFDM network, in which multi-relays can forward the source's message to base station. The uplink throughput is optimized by using decode-and-forward (DF) opportunistic relaying...
Relay transmission is an efficient solution to combat wireless channel fading and to increase system throughput in future board communication. In amplify-and-forward(AF) OFDM relay system, since the channel between the first hop (source-relay) and the second hop (relay-destination) varies independently, proper sub-carrier mapping (SCM) at the relay has been shown to improve the average end-to-end...
Cooperative diversity techniques have the huge potential capability on combining the time and space diversity gain of multiple antennas and the opportunistic scheduling gains. In this paper, we investigate suboptimal opportunistic cooperative scheme strategies for the edge-user based on low complexity equal power transfer and equal gain receive combine. The theoretical and Monte Carlo simulation analyses...
Cooperative communication is an efficient solution to combat wireless channel fading and to increase system throughput in future board communication. In this paper, we consider the uplink scenario of multi-user cooperative network, in which the resource is allocated to the users with the consideration of both fairness guarantee and throughput enhancement. The system uplink throughput is optimized...
Cooperative communication in multi-user orthogonal frequency division multiplexing (MU-OFDM) networks is a promising solution to combat wireless channel fading and to increase system throughput. In this paper, with the instantaneous channel state information (CSI) available at base station, the optimal resource allocation strategy is considered in MU-OFDM networks, which is to maximize throughput...
