Two problems on varieties of groups generated by wreath products

International Journal of Mathematics and Mathematical Sciences, 2002
We outline results on varieties of groups generated by Cartesian and direct wreath products of abelian groups and pose two problems related to our recent results in that direction. A few related topics are also considered.

Interlayer‐Sliding‐Enabled Multiferroicity and Giant Switchable Anomalous Hall Conductivity in RuO2Zn2F2 Bilayer

Advanced Science, EarlyView.
Interlayer sliding in the RuO2Zn2F2 bilayer induces ferroelectricity and enables reversible valley polarization switching. The electric dipole and valley‐resolved band edges are intimately coupled, revealing sliding ferroelectricity as a powerful mechanism for electrical control of valley degrees of freedom in 2D materials.

A Generative Neuro‐Symbolic AI for Protein Sequence Design

Advanced Science, EarlyView.
We introduce EffieDes, a neuro‐symbolic framework coupling deep learning‐based fitness landscape parameterization with exact automated reasoning. Unlike greedy sampling, EffieDes identifies sequences that globally optimize fitness while satisfying intricate design constraints.

Persistent homology based Bottleneck distance in hypergraph products

Applied Network Science
In this paper, we extended the technique of measuring similarity between topological spaces using bottle neck distance between persistence diagrams to hypergraph networks. Finding a relationship between the bottleneck distance of the Cartesian product of

Extending partial edge colorings of iterated cartesian products of cycles and paths [PDF]

Discrete Mathematics & Theoretical Computer Science
We consider the problem of extending partial edge colorings of iterated cartesian products of even cycles and paths, focusing on the case when the precolored edges satisfy either an Evans-type condition or is a matching.

Cation Diffusion‐Mediated Displaced Reaction‐Transformation in Green Steelmaking

Advanced Science, EarlyView.
The removal of O lattice atoms by environmental H2 at the surface of Fe3O4 results in Fe enrichment, driving the inward diffusion of Fe cations into the bulk. Through hopping between unoccupied and initially occupied sites, cation diffusion triggers a spatially displaced reaction‐transformation and drives subsequent dynamic phase transformations and ...

Dominating Cartesian products of cycles

Discrete Applied Mathematics, 1995
A set of vertices \(D\) in a graph is dominating if every vertex of the graph is adjacent to some vertex from \(D\). The domination number of the graph is the size of a smallest dominating set. The paper discusses the computation of the domination number of Cartesian products of graphs and an algorithm for finding minimum dominating sets in such graphs.

Empiricism without metaphysics: Regius’ Cartesian natural philosophy

, 2013
This chapter is devoted to the philosophy of Henricus Regius, a Dutch philosopher and one of the first followers of Descartes. Regius’ philosophy presents an original version of Cartesianism insofar as it relies on a certain number of Cartesian ...

Gap‐Free Information Transfer in 4D‐STEM via Fusion of Complementary Scattering Channels

Advanced Science, EarlyView.
Fused Full‐Field STEM (FF‐STEM) is introduced as a 4D‐STEM imaging modality that combines direct ptychography with tilt‐corrected dark‐field reconstruction in a single acquisition. Fourier‐space fusion using Wiener‐type spectral weighting closes the low‐frequency contrast gap inherent to bright‐field methods, delivering gap‐free, dose‐efficient, near ...

Quasi perfect codes in the cartesian product of some graphs

Electronic Journal of Graph Theory and Applications
An important question in the study of quasi-perfect codes is whether such codes can be constructed for all possible lengths n. In this paper, we address this question for specific values of n. First, we investigate the existence of quasi-perfect codes in
