Quasi‐Static to Supersonic Energy Absorption of Nanoarchitected Tubulanes and Schwarzites
Advanced Functional Materials, EarlyView.Nanoarchitected energy‐absorptive Tubulanes exhibit record energy absorption under quasi‐static conditions and exceptional inelastic energy dissipation under 750 m s−1 ballistics impact, with high performance spanning strain rates of 12 orders of magnitude.

Bio‐Inspired Molecular Events in Poly(Ionic Liquids)
Advanced Functional Materials, EarlyView.Originating from dipolar and polar inter‐ and intra‐chain interactions of the building blocks, the topologies and morphologies of poly(ionic liquids) (PIL) govern their nano‐ and micro‐processibility. Modulating the interactions of cation‐anion pairs with aliphatic dipolar components enables the tunability of properties, facilitated by “bottom‐up ...

An Algebraic Index Theorem for Non-smooth Economies [PDF]
In this paper, we prove an existence theorem for equilibria in production economies with increasing returns, which generalizes the classic results on this topic.

Topologic degree of some mappings [PDF]
Proceedings of the American Mathematical Society, 1954 1. In previous papers [2; 3], the problem of proving an existence theorem for a certain functional equation was reduced to that of computing the topological degree of a mapping in Euclidean n-space defined by homogeneous polynomials or infinite series. The complex case of the latter problem was solved in [4].

Computation for Topological Degree and Its Applications
Journal of Mathematical Analysis and Applications, 1996 Let \(A:\overline\Omega\to X\) be a condensing operator, where \(\Omega\) is a bounded open subset of the Banach space \(X\). A new method of computation for topological degree \(\deg(I-A,\Omega,0)=0\) is given and then applied to a class of systems of integral equations.

2D Magnetic and Topological Quantum Materials and Devices for Ultralow Power Spintronics
Advanced Functional Materials, EarlyView.2D magnets and topological quantum materials enable ultralow‐power spintronics by combining robust magnetic order with symmetry‐protected, Berry‐curvature‐driven transport. Fundamentals of 2D anisotropy and spin‐orbit‐coupling induced band inversion are linked to scalable growth and vdW stacking.

Mechanoregulatory Effects of Cell‐Scale Microwells on Epithelial Cell Phenotype
Advanced Functional Materials, EarlyView.In small polycaprolactone microwells, A549 epithelial cells span well edges, in contrast to cells growing on flat substrates. Focal adhesion sites (yellow) concentrate at topographic boundaries, while cytoskeletal tension (magenta stress fibers) is transmitted to the nucleus (blue), reducing nuclear sphericity.
