Advanced Engineering Materials, EarlyView.A two‐step approach combining laser powder bed fusion of FeSi electrical steel with Bakelite infiltration enables the fabrication of multifunctional gyroid lattice composites. The resulting structures exhibit high strength, magnetic anisotropy, and complete polymer infiltration, demonstrating a simple and scalable route toward lightweight, mechanically

Degree one maps between small 3-manifolds and Heegaard genus
, 2005 We prove a rigidity theorem for degree one maps between small 3-manifolds using Heegaard genus, and provide some applications and connections to Heegaard genus and Dehn surgery problems.Comment: Published by Algebraic and Geometric Topology at http ...

Topological representation of geometric theories [PDF]
Mathematical Logic Quarterly, 2012 AbstractUsing Butz and Moerdijk's topological groupoid representation of a topos with enough points, a ‘syntax‐semantics’ duality for geometric theories is constructed. The emphasis is on a logical presentation, starting with a description of the semantic topological groupoid of models and isomorphisms of a theory.

Advanced Engineering Materials, EarlyView.The work demonstrates that strategic wall‐thickness grading in diamond triply periodic minimal surface lattices enables precise tuning of deformation and failure behavior under compression. Different gradation patterns guide how and where the structure collapses, improving energy absorption or promoting controlled brittle failure.

Metric characterizations of spherical, and Euclidean buildings
, 2001 A building is a simplicial complex with a covering by Coxeter complexes (called apartments) satisfying certain combinatorial conditions. A building whose apartments are spherical (respectively Euclidean) Coxeter complexes has a natural piecewise ...

Advanced Functional Materials, EarlyView.In this study, the interplay of dipolar dynamics and ionic charge transport in MOF compounds is investigated. Synthesizing the novel structure CFA‐25 with integrated freely rotating dipolar groups, local and macroscopic effects, including interactions with Cs cations are explored.

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 ...

Geometric learning of knot topology
Soft MatterUnambiguous knot classification is a long-standing problem. In this paper, the authors use Machine Learning to classify all knots up to 10 crossings with more than 95% accuracy and also to distinguish knots with multiple identical knot polynomials.
