Its intrinsic wave properties lead to rich and distinct phenomena on galactic scales, including the suppression of low-mass halos by quantum pressure, the ubiquitous density granules and vortices by wave interference, and the formation of compact solitons at galactic centers. In this talk, I will highlight recent breakthroughs from our NTU group enabled by state-of-the-art FDM simulations. These include dynamical heating of galactic disks by FDM fluctuations, a refined soliton–halo relation, accelerated growth of supermassive black holes in the early universe, and a novel fluid–wave hybrid algorithm for solving the Schrödinger–Poisson equations. 11:00 - 12:00 Wei-Hsiang Lin (Institute of Molecular Biology, Academia Sinica, Taiwan) "Measuring and modeling the dynamics of E. coli growth and metabolism" In this talk, I will present two projects about cell growth and metabolism. The first project is experimental measurements of ATP dynamics, ATP homeostasis and cell growth. We used microfluidic device and fluorescence biosensors to record real-time dynamics of the intracellular ATP. ATP dynamics is correlated with cell cycle, and this correlation involves acetate fermentation. Time-series of ATP and growth rate is analyzed, showing a nontrivial cross-correlation pattern. The second project is constructing a theoretical framework for modeling cell exponential growth using a special class of ordinary differential equations (ODEs). Exponential growth is a common phenomenon in microorganisms, but how nonlinear system have exponential growth? We show that scalable functions, or homogeneous of degree one functions, are basic building blocks to modeling exponential growing systems. This approach can be extended to non-balanced growth and modeling ATP oscillation and cell cycle dynamics in the future. Overall, for complex systems such as cells, connecting experimental data with theoretical model is a long journey. We hope by interdisciplinary approach our understanding of growth systems will be deepen in the future.
