Geometry and arithmetic of crystallographic sphere packings [PDF]
Proceedings of the National Academy of Sciences, 2018 Significance This paper studies generalizations of the classical Apollonian circle packing, a beautiful geometric fractal that has a surprising underlying integral structure. On the one hand, infinitely many such generalized objects exist, but on the other, they may, in principle, be completely classified, as they fall into, only ...

The EKOR-stratification on the Siegel modular variety with parahoric level structure [PDF]
Épijournal de Géométrie AlgébriqueWe study the arithmetic geometry of the reduction modulo $p$ of the Siegel modular variety with parahoric level structure. We realize the EKOR-stratification on this variety as the fibers of a smooth morphism into an algebraic stack parametrizing ...

Advanced Engineering Materials, EarlyView.Coarse‐grained (left) and atomistic (right) models of the shape memory polymer ESTANE ETE 75DT3 are shown schematically. The two representations bridge molecular detail and mesoscopic description. Both models capture shape memory behavior, linking segmental mobility and conformational relaxation of anisotropic chains to macroscopic recovery, and ...

Vector Arithmetic in the Triangular Grid
Entropy, 2021 Vector arithmetic is a base of (coordinate) geometry, physics and various other disciplines. The usual method is based on Cartesian coordinate-system which fits both to continuous plane/space and digital rectangular-grids.

Advanced Functional Materials, EarlyView.An all‐in‐one analog AI accelerator is presented, enabling on‐chip training, weight retention, and long‐term inference acceleration. It leverages a BEOL‐integrated CMO/HfOx ReRAM array with low‐voltage operation (<1.5 V), multi‐bit capability over 32 states, low programming noise (10 nS), and near‐ideal weight transfer.

For lack of objects: Denying the constructive character of arithmetic [PDF]
Belgrade Philosophical AnnualKant's arithmetical judgements do not meet his standard for mathematical construction. In his view, mathematics is synthetic a priori because it constructs mathematical objects a priori. The method of constructing is not one that philosophy can mimic but

Advanced Functional Materials, EarlyView.Co‐assembly of rationally designed glycosaminoglycan‐binding peptides with sulfated glycosaminoglycans yields supramolecular hydrogels with tunable mechanics and matrix‐mediated cytokine retention. The glycosaminoglycans thereby act as cofactors, driving a coil‐to‐β‐sheet transition that triggers gelation.
