    Trends of pH decrease in the Mediterranean Sea through high frequency observational data: indication of ocean acidification in the basin Flecha, Susana, Pérez, Fiz F., García-Lafuente, Jesús, Sammartino, Simone, Ríos, Aida. F., Huertas, I. Emma

    出版 2015
    “...We document a remarkable decreasing annual trend of −0.0044 ± 0.00006 in the Mediterranean pH, which can be interpreted as an indicator of acidification in the basin based on high frequency records. Modeling pH data of the Mediterranean outflow allowed to discriminate between the pH values of its two main constituent water masses, the Levantine Intermediate Water (LIW) and the Western Mediterranean Deep Water (WMDW). ...”

    High-frequency, precise modification of the tomato genome Čermák, Tomáš, Baltes, Nicholas J., Čegan, Radim, Zhang, Yong, Voytas, Daniel F.

    出版 2015
    “...Even though donor molecules were replicated in the vectors, no evidence was found of persistent extra-chromosomal replicons or off-target integration of T-DNA or replicon sequences. CONCLUSIONS: High-frequency, precise modification of the tomato genome was achieved using geminivirus replicons, suggesting that these vectors can overcome the efficiency barrier that has made gene targeting in plants challenging. ...”

    Big data integration shows Australian bush-fire frequency is increasing significantly Dutta, Ritaban, Das, Aruneema, Aryal, Jagannath

    出版 2016
    “...In this study, we develop an ensemble method based on a two-layered machine learning model to establish relationship between fire incidence and climatic data. In a 336 week data trial, we demonstrate that the model provides highly accurate bush-fire incidence hot-spot estimation (91% global accuracy) from the weekly climatic surfaces. ...”
