Brief Summary: ''HiPSC-derived cardiomyocytes can form three-dimensional self-organized tissue rings... the trained tissue show matured features including increased cardiac-specific gene expression, enhanced Ca2+-handling properties, an increased oxygen-consumption rate, and enhanced contractile force. A mathematical model interprets the origination, propagation, and long-term behavior of the findings.''

Brief Summary: ''Computational automated routines and principal component analysis of the experimentally extracted Mallomonas data created a realistic mathematical model based on the Fibonacci pattern theory. A complete in silico scale case of Mallomonas was reconstructed showing an optimized scale coverage on the cell surface.''

Brief Summary: ''Using a novel method of three-dimensional analysis of the entire cell membrane of Dictyostelium cells, we found that PtdInsP3 domains can propagate persistently in any direction on the entire plasma membrane, while their propagation direction and speed are governed by the geometry of the cell.''

Brief Summary: ''The spatiotemporal dynamics of line defects in rotating spiral waves is observed. Combining a novel signaling over-sampling technique with multi-dimensional Fourier analysis shows that line defects can translate, merge, collapse and form stable singularities with even and odd parity while maintaining a stable oscillation of the spiral wave in the tissue.''
