triangulax: Differentiable Simulations with Triangular Meshes across Soft Matter Physics
Samuel Silliman, Qiwei Yu, Nikolas Claussen
Many physical and biological systems -foams, membranes, elastic shells, or tissue sheets- can be mathematically described as 2D surfaces. These surfaces can host complex dynamics,…
Bridging Control, Inference, Transport, and Thermodynamics: From Theory to Applications in Learning
Emmy Blumenthal, Nikolas Claussen, Benjamin Eysenbach +4
The last decade has seen the development of powerful methods for learning complex structure from high-dimensional data. These advances have brought to the foreground fundamental co…
Tissue shape from cell-scale active tensions
Nikolas H. Claussen, Fridtjof Brauns, Boris I. Shraiman
Connecting cell and tissue mechanics is a fundamental challenge in the physics of morphogenesis. Conventional elasticity theory is generally inapplicable: cytoskeletal turnover pre…
Emergent Elasticity and Quasiconformal Flow in Active Solids
Nikolas H. Claussen, Fridtjof Brauns, Boris I. Shraiman
A constitutive relation between stress and strain relative to a reference state is the basic assumption of elasticity theory. However, in living matter, force generation is governe…
A Mean-Field Model for Active Plastic Flow of Epithelial Tissue
Nikolas H. Claussen, Fridtjof Brauns
Animal morphogenesis often involves significant shape changes of epithelial tissue sheets. Great progress has been made in understanding the underlying cellular driving forces and…
Learning a conserved mechanism for early neuroectoderm morphogenesis
Matthew Lefebvre, Jonathan Colen, Nikolas Claussen +6
Morphogenesis is the process whereby the body of an organism develops its target shape. The morphogen BMP is known to play a conserved role across bilaterian organisms in determini…
A Geometric Tension Dynamics Model of Epithelial Convergent Extension
Nikolas H. Claussen, Fridtjof Brauns, Boris I. Shraiman
Convergent extension of epithelial tissue is a key motif of animal morphogenesis. On a coarse scale, cell motion resembles laminar fluid flow; yet in contrast to a fluid, epithelia…
