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.

The center of a graded connected Lie algebra is a nice ideal [PDF]

, 1996
Let (L(V),d) be a free graded connected differential Lie algebra over the field Q of rational numbers. An ideal I in the Lie algebra H(L(V),d) is called nice if, for every cycle alpha is an element of L(V) such that [alpha] belongs to I, the kernel of ...

Delta Ideals of Lie Color Algebras

Journal of Algebra, 1995
Let \(L\) be a Lie color algebra, possibly restricted, over a field \(K\) and graded by a finite abelian group \(G\). The authors show that if \(L\) has no nonzero elements with centralizers of countable codimension, then its enveloping algebra \(U(L)\) is ``symmetrically closed'' in the sense that it coincides with its symmetric Martindale quotient ...

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.

Generalized Higher Derivations on Lie Ideals of Triangular Algebras [PDF]

, 2017
Let be the triangular algebra consisting of unital algebras A and B over a commutative ring R with identity 1 and M be a unital (A; B)-bimodule. An additive subgroup L of A is said to be a Lie ideal of A if [L;A] ⊆ L.

Comparison of Triply Periodic Minimal Surface Energy Absorbers Under Uniaxial Compressive Loading

Advanced Engineering Materials, EarlyView.
This study investigates LCD 3D printed Triply Periodic Minimal Surface (TPMS) structures as mechanical energy absorbers. By comparing various base designs and layered combinations under uniaxial compression, it identifies that a Diamond‐Gyroid sandwich structure offers superior performance.

All‐in‐One Analog AI Hardware: On‐Chip Training and Inference with Conductive‐Metal‐Oxide/HfOx ReRAM Devices

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.
