Secondary metabolite (SM) production and development are correlated processes in fungi that are often coordinated by pleiotropic regulators. The eukaryotic regulators are critical players in mediating SM production related to fungal development, yet little data are available to support this hypothesis. In this study, a global regulator, RsdA (regulation of secondary metabolism and development), was...
This work focuses on the admission of new (secondary) users in a network where existing (primary) users are interference aligned. One of the challenges in this scenario is to achieve the promised degrees of freedom for the secondary users with limited available dimensions. We design a secondary admission network to achieve interference alignment as in equivalent general peer-peer networks, even when...
In this work, interference alignment is designed for peer-to-peer underlay MIMO cognitive radio network in which single primary user (PU) coexists with multiple secondary users (SUs). The proposed scheme chooses the transmit precoding and receiver interference subspace to minimize the total interference leakage while limiting the interference level to the PU. With perfect knowledge of local channel...
We consider a peer-to-peer cognitive radio (CR) network with single primary user and multiple secondary users. We propose an interference alignment technique for this network, and show that desired secondary user performances can be archived without degrading the primary user performance for both single and multiple antenna networks. For the multiple antenna networks, we optimize both the precoding...
In this paper, the emerging interference alignment technique is applied into the prevailing cognitive radio system. Dynamic spectrum access enables the secondary users to coexist with the licensed primary user in a cognitive radio system. However, to mitigate the intrinsic network interference of secondary users is becoming a challenge, even for the secondary network itself. Moreover, the primary...
An analysis is presented of the shielding effectiveness (SE) of a rectangular enclosure with an aperture in one face and thin metal wires aligned nearby inside. Compared with situations without thin metal wires, enhancement of shielding effectiveness by using thin metal wires is found. From the study of the simulation results of lots of specific situations, the strategy to use thin metal wires to...
