Motile cilia are eukaryotic organelles with essential chemo- and mechano-sensing functions across evolution, from single cell organisms to humans. of the mammalian nervous, respiratory reproductive systems characterized by unique motility proteins generate fluid flow for transporting metabolites removing mucus. The molecular mechanism motile biogenesis remains unknown. Here, we use mouse genetics, single-molecule assays, proteomics, high-resolution imaging, in situ cryo-tomography identify...
Tectonothermal evolution has an important control on maturity and hydrocarbon‐generation of source rocks. On the basis analysis present‐day geothermal gradient, rock thermophysical parameters heat flow, thickness contour vitrinite reflectance can be identified, distribution thermal anomaly was discussed. The paleogeotemperature paleogeothermal gradients are calculated after recovery erosional thickness. With theory recovering superposed modified sedimentary basin, evolutionary history since...
