- Recently diverged species often show incomplete reproductive isolation and subsequently experience hybridization and introgression. The plant genus Mimulus includes many such examples of closely related taxa that prove useful for studying incipient speciation. However, Sandstedt et al. show that in contrast to other Mimulus species, species of the M. tilingii complex are characterized by strong postzygotic isolation mediated by multiple barriers. This finding highlights the diverse speciation histories of related plant groups.

Performance-Enhanced Direct Detection Optical OFDM Transmission With CAZAC Equalization

- Direct detection optical orthogonal frequency division multiplexing (DDO-OFDM) transmission with constant amplitude zero autocorrelation (CAZAC) sequence equalization is proposed and experimentally demonstrated. Simulation results show that more than 2-dB peak-to-average power ratio (PAPR) reduction can be realized using CAZAC equalization, and 50-km standard single mode fiber (SSMF) transmission of 4.11-Gb/s QPSK-OFDM can be achieved with bit-error rate (BER) under forward error correction limit. Transmission performance of QPSK-based DDO-OFDM system is analyzed in both OB2B configuration and fiber link with and without CAZAC equalization. More than 2.5-dB optical receiver sensitivity improvements can be obtained thanks to the PAPR reduction enjoyed by CAZAC equalization. Signal-to-noise ratio for every subcarrier derived from error vector magnitude is estimated and its flatness is confirmed to be much improved with CAZAC equalization. The performance improvements brought by CAZAC equalization can be extended to other modulation formats, and 8.22-Gb/s 16-quadratic-amplitude modulation-OFDM signals transmission using CAZAC equalization is demonstrated with over 1.5 dB enhancement in receiver sensitivity.

- During a research stay at the Museo Egizio in September 2014* – which was targeting documents potentially written by the scribe of the necropolis Amennakhte1 (v) son of Ipuy (ii), such as P. Turin Cat. 1879+ TPOP Doc ID 9 (Turin Papyrus Map) and O. Turin CGT 57001 (Hymn to Ramesses IV) – we observed that the state of preservation of O. Turin CGT 57002 is much better2 than could be inferred from the facsimile, hieroglyphic transcription and picture published by López.3 This prompted us to build upon Bickel and Mathieu’s analysis4 and to study this piece anew.In this paper, we first provide a revised hieroglyphic transcription, an annotated translation and comments on the content and motivations for composing this hymn to Ptah. In a second step, we situate the text within the growing corpus of Amennakhte’s literary compositions. We then contextualize the hymn among the scribe’s expressions of religious piety and discuss the Sitz im Leben of this particular hymn. Finally, we argue that this text is likely to be an autograph. As such, the date of copy can be used as a chronologically fixed point for the analysis of Amennakhte’s handwriting.
