In this letter, we evaluate the performance of multicarrier code division multiple access (MC-CDMA) in terms of average bit error probability (BEP) in Nakagami fading channels. The results are applicable to MC-CDMA systems employing coherent demodulation with maximal-ratio combining (MRC) or equal gain combining (EGC) reception. The effects of fading parameters and number of users are presented...

The authors report on a randomized, controlled clinical trial on the treatment of posttraumatic stress disorder (PTSD), comparing manualized psychotherapy to wait-list control. This is the first study to evaluate Brief Eclectic Psychotherapy (BEP), which combines cognitive-behavioral and psychodynamic approaches within one treatment method. Forty-two police officers with the diagnosis of PTSD p...

Abstract — Consider a code-division multipleaccess system in a correlated Rayleigh fading environment in which the fading gains are independent among the users but correlated among the receive diversity branches, and which uses the decorrelating multiuser detector. The branches are combined using maximal-ratio combining, which requires channel estimation. The channel is estimated by means of pi...

It has been shown previously (Porter et al., Cancer Res., 45: 2050-2057, 1985) that the N1,N8-bis(ethyl) derivative of spermidine has significant antiproliferative activity which appears to derive from its regulatory effects on the polyamine biosynthetic pathway, particularly on ornithine decarboxylase activity. In the present study, N1,N4-bis(ethyl)putrescine (BEP) and N1,N12-bis(ethyl)spermin...

In order to increase the capacity of TDMA cellular radio networks, the reuse factor may be recduced. However, in this case the system performance is limited by cochannel interference, unless cochannel interference cancellation is done. Therefore, cochannel interference cancellation is a hot topic at the moment. Assuming perfect knowledge of the channel coefficients of the desired user and the i...

Many combinatorial optimization problems do not have a clear structure, may present many side constraints, and may include subproblems. In addition, different instances within the same domain can have different structure and characteristics. As a consequence it is commonplace that a single algorithm is not the best performer on every problem instance. We consider an algorithm portfolio approach...
