Journal of Physics CommunicationsWe fabricated chiral three-dimensionally (3D) periodic photonic crystals (PPCs) with nanoscale features by: first etching two different two-dimensionally (2D) periodic patterns in fused silica and silicon substrates, and then implementing temporally ...

Structure theorems for idempotent residuated lattices [PDF]
, 2020 In this paper we study structural properties of residuated lattices that are idempotent as monoids. We provide descriptions of the totally ordered members of this class and obtain counting theorems for the number of finite algebras in various subclasses.

The Electronic Journal of Combinatorics, 2008 A flat of a matroid is cyclic if it is a union of circuits; such flats form a lattice under inclusion and, up to isomorphism, all lattices can be obtained this way. A lattice is a Tr-lattice if all matroids whose lattices of cyclic flats are isomorphic to it are transversal. We investigate some sufficient conditions for a lattice to be a Tr-lattice; a

Evaluating Energy Absorption Performance of Filled Lattice Structures
Advanced Engineering Materials, EarlyView.Maximum stress must be considered to robustly evaluate energy absorber designs. This approach was applied to compare all types of absorbers in a single Ashby diagram and determine the utility of filling lattice voids with a second material. High‐performance fillers can improve the performance of lattices that are limited by buckling or catastrophic ...

European Journal of Combinatorics, 1994 A lattice dicing is a finite set \(\{G_ 1, \dots, G_ r\}\) of \(D\)- families of parallel hyperplanes in \(\mathbb{R}^ n\) which is both non- degenerate and vertex-regular, where the three needed terms are correspondingly defined as follows: A \(d\)-family contains an infinite number of equispaced parallel hyperplanes ``extending in both directions ...

Low‐Angle Grain Boundaries and Re‐Segregation in Single‐Crystalline Ni‐Base Superalloys
Advanced Engineering Materials, EarlyView.This work demonstrates that Re‐segregation at low‐angle grain boundaries (LAGBs) in Ni‐base superalloys is influenced by misorientation angle. Advanced microscopy and atom probe tomography reveal that higher misorientation angles increases Re‐segregation.

A New Constant-Size Group Signature Scheme From Lattices
IEEE Access, 2020 A lattice-based group signature scheme (LGSS) is an active cryptographic primitive, where each group member can sign messages anonymously in the name of the entire group and each valid signature should be traced to some group member on the lattice.
