The effect of emotions on pain perception is generally recognized but the underlying mechanisms remain unclear. Here, emotions related to pain were induced in healthy volunteers using hypnosis, during 1-min immersions of the hand in painfully hot water. In Experiment 1, hypnotic suggestions were designed to induce various positive or negative emotions.(More)
In this paper, the outage probability (OP) of dual-hop cognitive amplify-and-forward (AF) relay networks subject to independent non-identically distributed (i.n.i.d.) Nakagami-m fading is examined. We assume a spectrum-sharing environment, where two different strategies are proposed to determine the transmit powers of the secondary network. Specifically,(More)
Relay communication has advantages over direct transmission in terms of secrecy capacity. In this paper, the performance of secrecy, offered by multihop decode-and-forward relaying, is investigated and compared to its counterpart in direct transmission. Three key performance measures are derived over Rayleigh fading channels: probability of non-zero secrecy(More)
This paper is concerned with performance analysis of cognitive underlay partial relay networks with imperfect channel state information (CSI). To assure the required quality of service (QoS) at primary receivers, transmit power at secondary nodes is adjusted by using a back-off power scheme under imperfect CSI condition. The back-off power strategy reduces(More)
We consider the Cauchy problem for a non-autonomous nonclassical diffusion equation of the form ut − ε∆ut −∆u+ f(u) + λu = g(t) on Rn. Under an arbitrary polynomial growth order of the nonlinearity f and a suitable exponent growth of the external force g, using the method of tail-estimates and the asymptotic a priori estimate method, we prove the existence(More)
Decode and Forward (DF) is a type of opportunistic relay in which the packet is relayed only when the direct transmission of information from source to the destination fails. This results in bandwidth optimization of the overall system as well as considerable saving of resources by avoiding the unnecessary relay of information when it is not required. In(More)
In cognitive spectrum sharing systems, interference probability (IP) is one of the most important performance metrics illustrating the interference level at the primary network. In this paper, the interference probability of the primary network due to secondary underlay partial relay selection networks is investigated under the assumption of imperfect(More)
Selection decode-and-forward (DF) relaying and incremental relaying were introduced as efficient relaying protocols to increase capacity and performance of cooperative diversity networks. This paper proposes an incremental relaying in conjunction with selection DF and provides its performance in terms of outage probability and bit error probability. Our(More)
Selection relaying (SR) achieves the powerful benefits of multi-antenna systems without the need for physical arrays. It is theoretically shown that when the relay measures loglikelihood ratio (LLR) instead of signal-to-noise ratio (SNR) to decide whether or not to forward the recovered symbols to the destination, the performance of SR with equal energy(More)
