Phenotypic plasticity has been proposed as an important adaptive strategy for clonal plants in heterogeneous habitats. Increased phenotypic plasticity can be especially beneficial for invasive clonal plants, allowing them to colonize new environments even when genetic diversity is low. However, the relative importance of genetic diversity and phenotypic plasticity for invasion success remains l...

Telomerase and systems controlling their activity have been of great attention. There are controversies regarding the role of the alternative splicing forms of the human telomerase reverse transcriptase (hTERT), the catalytic subunit of telomerase. Therefore, the correlation between telomerase enzyme activity, the abundance of alternatively spliced variants of hTERT and doubling time of a seri...

Abstract. In this paper, full rate space-time-frequency coding applied to orthogonal frequency division multiplexing based power line communication systems. The proposed systems yield both time and frequency diversity and keep transmission rate full. Performances of the systems are evaluated for three conductors of low voltage indoor cables and are compared with space-frequency and space-time-f...

Diversity estimates play a key role in ecological assessments. Species richness and abundance are commonly used to generate complex diversity indices that are dependent on the quality of these estimates. As such, there is a long-standing interest in the development of monitoring techniques, their ability to adequately assess species diversity, and the implications for generated indices. To dete...

In this paper, we analyze the performance of bit interleaved coded multiple beamforming (BICMB). We provide interleaver design criteria such that the resulting system achieves full spatial multiplexing of min(N, M) and full spatial diversity of NM for a system with N transmit and M receive antennas. We combined BICMB with OFDM in order to combat ISI caused by the frequency selective channels. T...

| We consider the design of phase shift keyed space-time coded modulation for two antenna systems based on linear codes over rings. Design rules for constructing full diversity systematic space-time codes based on underlying existing algebraic codes were rst presented by Hammons and El Gamal in 2000. We reformulate and simplify these design rules, resulting in the condition that the characteris...
