On the relationship between topological and geometric defects [PDF]
Journal of Physics: Condensed Matter, 2017 The study of topology in solids is undergoing a renaissance following renewed interest in the properties of ferroic domain walls as well as recent discoveries regarding topological insulators and skyrmionic lattices. Each of these systems possess a property that is `protected' in a symmetry sense, and is defined rigorously using a branch of mathematics

Advanced Engineering Materials, EarlyView.This article examines how build orientation, thickness, and loading rate affect the tensile and compressive properties of LS‐manufactured polyamide 12 12 parts. Through over 120 experiments, it reveals strong ductility anisotropy in tension, minimal compressive sensitivity, and significant thickness and strain rate dependencies.

Topology of Entanglement in Multipartite States with Translational Invariance
, 2013 The topology of entanglement in multipartite states with translational invariance is discussed in this article. Two global features are foundby which one can distinguish distinct states.

Advanced Engineering Materials, EarlyView.Additive manufacturing (AM) transforms space hardware by enabling lightweight, high‐performance, and on‐demand production. This review outlines AM processes—powder bed fusion (PBF), directed energy deposition (DED), binder jetting (BJ), sheet lamination (SL), and material extrusion (ME)—applied to propulsion, satellite structures, and thermal devices ...

Isomorphism of spaces of analytic functions on n-circular domains [PDF]
, 2006 The space A(D) of all analytic functions in a complete n-circular do- main D in Cn; n 2; is considered with a natural Fréchet topology. Some su¢ cient conditions for the isomorphism of such spaces are ob- tained in terms of certain subtle geometric ...

All flat manifolds are cusps of hyperbolic orbifolds
, 2002 We show that all closed flat n-manifolds are diffeomorphic to a cusp cross-section in a finite volume hyperbolic (n+1)-orbifold.Comment: Published by Algebraic and Geometric Topology at http://www.maths.warwick.ac.uk/agt/AGTVol2/agt-2-13.abs ...

Advanced Engineering Materials, EarlyView.This study explores the ablation efficiency and surface quality of laser‐treated stainless steel alloys (AISI 304, AISI 420, and AISI 316Ti) using an ultrashort pulsed laser and varying burst parameters (MHz, GHz, and Bi‐burst). Both ablation rates and surface quality parameters are determined, including isotropy surface roughness values, highlighting ...
