In this paper, we study the Diversity-Multiplexing Tradeoff (DMT) of the Decode or Quantize and Forward (DoQF) protocol recently proposed in [1] for the half duplex single relay channel. Our results show that this static relaying protocol achieves the 2 by 1 MISO bound for multiplexing gains r < 0.25. The DMT of the classical non orthogonal Decode and Forward (DF) protocol is also derived. We s...

Synthesis is described for the haptens 23-demycinosyl-23-deoxy-23-(3-aminoprop-1-yl)-aminotilmicosin (6) from 5-O-mycaminosyltylonolide (OMT) and for 23-demycinosyl-23-deoxy-23-(3-aminoprop-1-yl)-amino-20-dihydrotylosin (10) from demycinosyltylosin (DMT), respectively. The mild reaction conditions used to synthesize the second hapten, DMT derivative 10, were necessary to overcome instabilities ...

elecommunications operators are responding to the competitive threat of cable and satellite services by offering high-speed applications and converged services to residential and business customers. These applications generally require minimum duplex bit rates in the range of 5 to 6 Mbits/second—both upstream and downstream (symmetric). While there are several digital subscriber line (DSL) tech...

Morphine, which is agonist for μ-opioid receptors, has been used as an anti-pain drug for millennia. The opiate antagonists, naloxone and naltrexone, derived from morphine, were employed for drug addiction and alcohol abuse. However, these exogenous agonists and antagonists exhibit numerous and unacceptable side effects. Of the endogenous opioid peptides, endomorphin(EM)-1 and endomorphin(EM)-2...

Inorganic iron can be transported into cells in the absence of transferrin. Ferric iron enters cells utilizing an integrin-mobilferrin-paraferritin pathway, whereas ferrous iron uptake is facilitated by divalent metal transporter-1 (DMT-1). Immunoprecipitation studies using antimobilferrin antibody precipitated the previously described large-molecular-weight protein complex named paraferritin. ...

The Disaster Management Tool (DMT) supports information management during crises. It has been designed to support field workers, on-site coordination centers and headquarters by facilitating an efficient flow of information between them. In this paper we describe the functionality and architecture of the DMT and give insight into our development process over the last four years. The DMT has und...

Diversity-multiplexing tradeoff (DMT) characterizes the fundamental relationship between the diversity gain in terms of outage probability and the multiplexing gain as the normalized rate parameter , where the limiting transmission rate is given by (here, SNR denote the received signal-to-noise ratio). In this paper, we analyze the DMT and outage performance of an underwater network with a coop...

Cooperative relay communication in a fading channel environment under the orthogonal amplify-and-forward (OAF), non-orthogonal and orthogonal selection decode-andforward (NSDF and OSDF) protocols is considered here. The diversity-multiplexing gain tradeoff (DMT) of the three protocols is determined and DMT-optimal distributed space-time code constructions are provided. The codes constructed are...

The antiestrogen tamoxifen (TAM) is extensively metabolized by cytochrome P-450 in humans and rodents. The active, estrogen receptor-binding metabolites, 4-hydroxy TAM (OHT) and N-desmethyl TAM (DMT) have been well characterized. We showed that the s.c. injection of 1 mg/kg TAM in adult female Sprague Dawley rats bearing carcinogen-induced mammary tumors resulted in rapid serum decline of paren...

In this article, we consider the diversity-multiplexing tradeoff (DMT) of relay-assisted communication through correlated frequency selective fading channels. Recent results for relays in flat fading channels demonstrate a performance and implementation advantage in using relay selection as opposed to more complicated distributed space-time coding schemes. Motivated by these results, we explore...
