Optimization of graded porous acoustic absorbers based on triply periodic minimal surfaces [PDF]
Materials & DesignThe acoustic absorption of a porous structure within a specific frequency range can be tuned by varying its porosity along its thickness. In this work, triply periodic minimal surfaces (TPMS) are employed to generate graded porous structures, where the ...

Optimized 3D Watermarking for Minimal Surface Distortion [PDF]
IEEE Transactions on Image Processing, 2013 This paper proposes a new approach to 3D watermarking by ensuring the optimal preservation of mesh surfaces. A new 3D surface preservation function metric is defined consisting of the distance of a vertex displaced by watermarking to the original surface, to the watermarked object surface as well as the actual vertex displacement.

Heart wall myofibers are arranged in minimal surfaces to optimize organ function [PDF]
Proceedings of the National Academy of Sciences, 2012 Heart wall myofibers wind as helices around the ventricles, strengthening them in a manner analogous to the reinforcement of concrete cylindrical columns by spiral steel cables [Richart FE, et al. (1929) Univ of Illinois, Eng Exp Stn Bull 190].

Nonlocal approximation of minimal surfaces: optimal estimates from stability
arXiv, 2023 Minimal surfaces in closed 3-manifolds are classically constructed via the Almgren-Pitts approach. The Allen-Cahn approximation has proved to be a powerful alternative, and Chodosh and Mantoulidis (in Ann. Math. 2020) used it to give a new proof of Yau's conjecture for generic metrics and establish the multiplicity one conjecture.
