Representation of Cubic Lattices by Symmetric Implication Algebras
Order, 2006 A lattice \(L\) is called cubic [\textit{J. S. Oliveira}, The theory of cubic lattices. PhD thesis, MIT (1992)] if (1) for \(x \in L\), there is an order-preserving map \(\Delta_x:(x]\to(x]\); (2) \(\Delta^2_x=\text{Id}_{(x]}\); (3) for ...

The prime filter theorem of lattice implication algebras
International Journal of Mathematics and Mathematical Sciences, 2001 Using a special set x−1F, we give an equivalent condition for a filter to be prime, and applying this result, we provide the prime filter theorem in lattice implication ...

Ultra $LI$-ideals in lattice implication algebras [PDF]
, 2002 summary:We define an ultra $LI$-ideal of a lattice implication algebra and give equivalent conditions for an $LI$-ideal to be ultra. We show that every subset of a lattice implication algebra which has the finite additive property can be extended to an ...

On Relationships of Filters in Lattice Implication Algebra
, 2007 In this paper, we focus on the properties of filters in lattice implication algebra. We study the relationship of associative filter and implicative filter, n-fold associative filter and n-fold implicative filter in detail. And a sufficient condition of involution filter in lattice implication algebra is proved. Then the relationship of some filters is

The variety generated by order algebras [PDF]
, 2002 Every ordered set can be considered as an algebra in a natural way. We investigate the variety generated by order algebras. We prove, among other things, that this variety is not finitely based and, although locally finite, it is not contained in any ...

Advanced Science, EarlyView.A conversion‐resolved constitutive framework is developed for the hydrogen‐based direct reduction of iron oxide pellets. Effective reaction and transport timescales are inferred directly from measured trajectories and mapped against operating conditions, pellet architecture, and composition. The analysis reveals how late‐stage transport control emerges

Symmetry‐Imposed Selection Rules for Excitations of Nontrivial Plasmonic Topologies
Advanced Science, EarlyView.A unified group‐theory selection rule governs the excitation of vectorial nearfield topologies across three plasmonic spin states. Derived from first principles, it predicts spin–orbit vortex splitting and multidimensional nested vortices, confirmed by phase‐resolved in situ measurements.

Advanced Science, EarlyView.Sr1−xBaxCo2V2O8 is established as a magnetic‐ion‐based proper displacive ferroelectric whose transition is continuously suppressed by Ba substitution to a ferroelectric quantum critical point. In the resulting quantum paraelectric regime, a transverse magnetic field induces magnetic quantum criticality, realizing multiferroic quantum criticality and ...

SPICE‐Compatible Compact Modeling of Cuprate‐Based Memristors Across a Wide Temperature Range
Advanced Electronic Materials, EarlyView.A physics‐guided compact model for YBCO memristors is introduced, incorporating carrier trapping, field‐induced detrapping, and a differential balance equation to describe their switching dynamics. The model is compared with experiments and implemented in LTspice, allowing realistic circuit‐level simulations.

AIChE Journal, EarlyView.ABSTRACT Conceptual process design combines discrete configuration choices with continuous operating decisions, often yielding difficult mixed‐integer nonlinear or simulation‐based optimization problems. This work presents an exploratory computational assessment of Ising‐based solvers, simulated annealing, quantum annealing, and entropy computing, as ...
