    Martínez-Maldonado, Fabio Ernesto; Castaño Marín, Angela María; Góez Vinasco, Gerardo Antonio; Ricardo Marin, Fabio (MDPI; Basel (Switzerland), 2022)
    Estimating gross primary production (GPP) is important to understand the land–atmosphere CO2 exchange for major agroecosystems. Eddy covariance (EC) measurements provide accurate and reliable information about GPP, but flux measurements are often not available. Upscaling strategies gain importance as an alternative to the limitations of the use of the EC. Although the potato provides an important agroecosystem for ...

  • Modeling cell size regulation under complex and dynamic environments 

    Nieto, Cesar; Vargas García, Cesar; Pedraza, Juan Manuel; Singh, Abhyudai (Cold Sprimg Harbor Laboratory - CSH; California (Estados Unidos), 2022)
    In nature, cells face changes in environmental conditions that can modify their growth rate. In these dynamic environments, recent experiments found changes in cell size regulation. Currently, there are few clues about the origin of these cell size changes. In this work, we model cell division as a stochastic process that occurs at a rate proportional to the size. We propose that this rate is zero if the cell is smaller ...
