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 ...

Closed Lie Ideals in Operator Algebras
, 1981 If M is an associative algebra with product xy, M can be made into a Lie algebra by endowing M with a new multiplication [x, y] = xy – yx. The Poincare-Birkoff-Witt Theorem, in part, shows that every Lie algebra is (Lie) isomorphic to a Lie subalgebra of

Advanced Engineering Materials, EarlyView.Composite Ti–6Al–4V–epoxy lattice structures are additively manufactured and epoxy infiltrated for cyclic loading. At low lattice volume fractions, hybridization produces synergistic gains in stiffness and energy dissipation. At higher volume fractions, synergy diminishes, although composites still exceed metallic lattices in specific energy ...

A construction of some ideals in affine vertex algebras
International Journal of Mathematics and Mathematical Sciences, 2003 We study ideals generated by singular vectors in vertex operator algebras associated with representations of affine Lie algebras of types A and C. We find new explicit formulas for singular vectors in these vertex operator algebras at integer and half ...

Ufuldkommenhedens etik: Om at realisere sufismen som dydsetik i det post-sovjetiske Usbekistan
Tidsskrift for Islamforskning, 2017 With a point of departure in fieldwork conducted among Muslims connected with – or inspired by – the Naqshbandiyya Sufi tariqa in Post-Soviet Uzbekistan, this paper focuses on the paradoxes involved in realizing Sufism as virtue ethics.

From Shear to Sound: Mechanics–Acoustics Mapping of TPMS Lattices
Advanced Engineering Materials, EarlyView.Triply periodic minimal surface (TPMS) lattices are mapped across mechanical and acoustic performance, revealing that descriptors validated in compression fail under shear. First‐time comparison with trusses included. A transition from porous to resonance‐driven absorption emerges at 25% density.

Influence of Geometric Design on Mechanical Performance of Auxetic Metastructure
Advanced Engineering Materials, EarlyView.Strategic geometric reinforcement transforms auxetic performance. This study evaluates 3D‐printed arrowhead metastructures, revealing that a modified design with local ring reinforcement suppresses premature failure to achieve superior energy absorption and structural efficiency.

On ideals of free lie algebras
, 1987 The only possible ideals which are finitely generated as subalgebras of a free Lie algebra are the zero ideal or the whole algebra. This should not be understood as “all nontrivial ideals which have infinite rank are proper ideals”.In this paper we prove
