On Bipartite Biregular Large Graphs Derived From Difference Sets
Journal of Graph Theory, EarlyView.ABSTRACT A bipartite graph G = ( V , E ) $G=(V,E)$ with V = V 1 ∪ V 2 $V={V}_{1}\cup {V}_{2}$ is biregular if all the vertices of each stable set, V 1 ${V}_{1}$ and V 2 ${V}_{2}$, have the same degree, r $r$ and s $s$, respectively. This paper studies difference sets derived from both Abelian and non‐Abelian groups.

Journal of Magnetic Resonance Imaging, EarlyView.ABSTRACT Conventional MRI is limited in imaging tissues with short T2 relaxation times, such as bone, ligaments, and cartilage, due to their rapid signal decay. This limitation has spurred the development of specialized MRI techniques designed specifically for short‐T2 tissue imaging.

Global and microlocal aspects of Dirac operators: Propagators and Hadamard states
Mathematische Nachrichten, EarlyView.Abstract We propose a geometric approach to construct the Cauchy evolution operator for the Lorentzian Dirac operator on Cauchy‐compact globally hyperbolic 4‐manifolds. We realize the Cauchy evolution operator as the sum of two invariantly defined oscillatory integrals—the positive and negative Dirac propagators—global in space and in time, with ...

Psychology &Marketing, EarlyView.ABSTRACT Although studies have explored user experience (UX) with artificial intelligence (AI)‐powered voice assistants (VAs), the cognitive, psychological, and emotional factors affecting user engagement and experience with VAs have yet to be investigated in depth. Drawing on cognitive absorption and broaden‐and‐build theories, this study investigates

Managerial and Decision Economics, EarlyView.ABSTRACT Managers often say that they want to make their company more profitable by increasing the unit margin, operating margin, or margin rate, making these strategic objectives. There is some confusion in their language, as these three metrics seem to be equivalent to maximum profit.
