3D‐Printed Architected Material for the Generation of Foam‐Based Protective Equipment
Advanced Engineering Materials, EarlyView.This study investigates 3D‐printed architected structures as alternatives to traditional foams in protective gear. It focuses on customizing impact strength and damping through design and manufacturing integration. Testing shows these structures outperform conventional foams, offering enhanced customizability, lower weight, and tunable performance ...

A Quantization Procedure of Fields Based on Geometric Langlands Correspondence
International Journal of Mathematics and Mathematical Sciences, 2009 We expose a new procedure of quantization of fields, based on the Geometric Langlands Correspondence. Starting from fields in the target space, we first reduce them to the case of fields on one-complex-variable target space, at the same time increasing ...

Ribbons: Their Geometry and Topology [PDF]
Computer-Aided Design and Applications, 2004 AbstractRibbons may be used for the modeling of DNAs and proteins. The topology of a ribbon can be described by the link Lk, while its geometry is represented by the writhe Wr and the twist Tw. These three quantities are numerical integrals and are related by a single formula from knot theory.

Advanced Engineering Materials, EarlyView.Primary phases and a fatigue crack are studied in a forged blank of an aluminum alloy using synchrotron and laboratory X‐ray computed tomography. To image the crack, the fatigue test is interrupted, and a static tensile load is applied to open the crack.

Billey's formula in combinatorics, geometry, and topology [PDF]
, 2013 In this expository paper we describe a powerful combinatorial formula and its implications in geometry, topology, and algebra. This formula first appeared in the appendix of a book by Andersen, Jantzen, and Soergel.

Advanced Engineering Materials, EarlyView.This study presents a 3D representative volume element‐based simulation approach to predict mesoscopic residual stress and strain fields in silicon solid solution‐strengthened ductile cast iron. By modeling phase transformation kinetics with an enhanced Johnson–Mehl–Avrami–Kolmogorov model, the effects of varying cooling rates on residual stresses are ...

Points and topologies in rigid geometry
Mathematische Annalen, 1995 Let \(X\) be an affinoid space over a complete nonarchimedean field. The usual points of \(X\) are not sufficient to investigate sheaves on \(X\); for instance, there exist sheaves of \({\mathcal O}_{\mathcal X}\)-modules with all stalks equal to (0) and which are not (0).

Advanced Engineering Materials, EarlyView.Cubic Bézier curves are used in the synthesis of novel surface‐based metamaterials with tunable mechanical properties. Surface‐based geometries are 3D printed and tested in compression. The resulting mechanical properties are correlated to changes in the shape of the base curve, with high potential in energy absorption through the adjustment of their ...

A metrizable semitopological semilattice with non-closed partial order
Topological Algebra and its Applications, 2020 We construct a metrizable semitopological semilattice X whose partial order P = {(x, y) ∈ X × X : xy = x} is a non-closed dense subset of X × X. As a by-product we find necessary and sufficient conditions for the existence of a (metrizable) Hausdorff ...
