... higher values of N, it may be worth cal- culating Equation (9) for some more values of m. 4 Conclusion We analyze the PD of M-QAM-modulated OFDM sym- bols. Theoretically, the PD of the mth OFDM symbol with ... domain OFDM sym- bol together with the cyclic prefix. Since the cyclic prefixisthecopyofapartofx, the derivation of the distribution of the samples in x co mpletely determin...

... ,k}, where F(D) is the family of all finite sets of D. Using Lemmas 3.4 and 3.6 we will show that Proposition 3.7. G is a countable base of the weak topology in ˜ C. Proof. Clearly G is co untable. ... proposition is proved.  The proof of the theorem is finished. Thus, since ˜ C equipped with the weak topo logy is a metric space, we can define the notion of weak convergence of a seq...

... current value of sample NP-2 was about one order of magnitude higher than that of reference samples (10 −3 A/cm 2 ), due to the smaller barrier height of NP-2 (0.87 eV) compared with that of Ref ... the value of 5.18 × 10 5 for Ref. The increased electric field of the samples with the Au and Ag NPs is mainly attributed to the reduction of barrier height as the effective...

... mechanisms of action could offer an additional strategy against drug resistance of viruses. Several examples of non-nucleoside inhibitors have been proposed as candidate drugs for the treatment of ... drug used on treatment of HSV infections [3–5]. However, the widespread use of these compounds has been associated with the emergence of drug-resistant HSV strains [5]. The...
