  • thz and above thz electron or hole oscillations in dna dimers and trimers
    Annalen der Physik, 2014
    Co-Authors: K Lambropoulos, Konstantinos Kaklamanis, Georgios Georgiadis, Constantinos Simserides
    Abstract:

    A non conventional source or receiver of THz and above THz electromagnetic radiation is proposed. Specifically, electron or hole oscillations in DNA dimers (two interacting DNA base-pairs or monomers) are predicted, with frequency in the range 0.25–100 THz (period 10–4000 fs) i.e. potentially absorbing or emitting electromagnetic radiation mainly in the mid- and far-infrared with wavelengths ≈ 3–1200 μm. The efficiency of charge Transfer between the two monomers which make up the dimer is described with the Maximum Transfer percentage p  and the pure Maximum Transfer Rate . For dimers made of identical monomers , but for dimers made of different monomers . The investigation is extended to DNA trimers (three interacting DNA base-pairs or monomers). For trimers made of identical monomers the carrier oscillates periodically with 0.5–33 THz ( 30–2000 fs); for 0 times crosswise purines , for 1 or 2 times crosswise purines . For trimers made of different monomers the carrier movement may be non periodic. Generally, increasing the number of monomers above three, the system becomes more complex and periodicity is lost; even for the simplest tetramer the carrier movement is not periodic.

  • Research on Physical Layer Network Coding Technology in Wireless Network

    Abstract:

    Abstract: Recently, Network coding has been proved to be the breakthrough in the research field of network and communication. It is an effective technique to increase network capacity and improve the robustness and reliability of networks. In this paper, there is application of network coding in wireless network. In order to improve the reliability and the throughput of wireless network, we do extensive research on network coding incorpoRated with the multicast communication in WLAN, the routing optimization in multi-hop network and the retransmission efficiency for wireless broadcast system, and focus on the protocol design and the theory for the performance analysis. On the basis of introduction on basic idea and method of network coding, we proposes a new physical layer network coding scheme for two-way relay channel model based on a belief propagation approach. Then we make performance analysis through numerical simulation. Theoretical Introduction of Network coding Network coding allows the intermediate nodes in the routing method based on the traditional store and forward the received plurality of data packets to perform coding operation. Generally speaking, network coding has the following characteristics: In the multicast environment, network coding can reach a Maximum Transfer Rate; and save network bandwidth consumption and improve spectru
