    A mechanical model is proposed for the mixture of tissues in the breast as a function of the fat content. A multiscale modelling approach was applied in a finite element model of a representative volume element(RVE) of tissue. The RVE was subjected to several load cases from which the constitutive equations of the homogenized tissue were fitted. The results confirm that the fat volume ratio is a key factor, but the spatial distribution of fat is not so important.

    Cryo-electron microscopy (cryo-EM) is a key technology for the structure determination of large biomolecules. However, it suffers from low signal-to-noise ratio and low resolution. We introduce persistent homology, a new branch of algebraic topology, to guild the noise removal with Laplace– Beltrami flow, which is found to preserve the intrinsic topological fingerprints of cryo-EM structures and diminish the topological signature of noise. Additionally, as shown in the figure, the conventional structure determination of cryo-EM data is an ill-posed inverse problem: two fitted structures have the same good correlation coefficients. We resolve this problem by analyzing the topology fingerprints, which gives rise to a unique solution.
