    Positively selected amino acid replacements within the RuBisCO enzyme of oak trees are associated with ecological adaptations. by Carmen Hermida-Carrera, Mario A Fares, Ángel Fernández, Eustaquio Gil-Pelegrín, Maxim V Kapralov, Arnau Mir, Arántzazu Molins, José Javier Peguero-Pina, Jairo Rocha, Domingo Sancho-Knapik, Jeroni Galmés

    Published 2017-01-01
    “…It has been hypothesized that RuBisCO has evolved differentially depending on the environmental conditions and leaf traits governing internal gas diffusion patterns. Here, we show, using PAML, that amino acid replacements at the residue positions 95, 145, 251, 262 and 328 of the RuBisCO large subunit have been the subject of positive selection along particular Quercus lineages associated with the leaf traits and climate characteristics. …”

    Channel impulse response insensitive feature for non-coherent signal detection in molecular communication by Limin XIAO, Xiangrong XU, Zhuangkun WEI, Shenghan LIU, Yiwen LIU

    Published 2020-09-01
    “…To solve the inter-symbol interference (ISI) and background noise challenges of molecular communication via diffusion (MCvD),four ISI-resistant signal-features were deployed,and a reliable non-coherent signal detection algorithm,which was insensitive to different types of molecular channel impulse response (CIR),was proposed.Also,an adaptive decision threshold and theoretical bound of bit error rate (BER) were deduced.Simulation results demonstrate a lower BER of the proposed non-coherent scheme compared to the state-of-the-art schemes in the same order of computational complexity,therefore suggesting its potential applications for future nano-scale MC.…”
