Edge-Stable Equimatchable Graphs
, 2018 A graph $G$ is \emph{equimatchable} if every maximal matching of $G$ has the same cardinality. We are interested in equimatchable graphs such that the removal of any edge from the graph preserves the equimatchability.

Energy Science &Engineering, EarlyView.ABSTRACT There is a need to develop an improved insulating material that surpasses traditional insulators in terms of insulation and efficient operation under extreme weather conditions. Epoxy nanocomposites (NCs) have gained considerable attention due to their intrinsic material properties.

Perfect State Transfer in Laplacian Quantum Walk [PDF]
, 2014 For a graph $G$ and a related symmetric matrix $M$, the continuous-time quantum walk on $G$ relative to $M$ is defined as the unitary matrix $U(t) = \exp(-itM)$, where $t$ varies over the reals.

Wishart distributions for decomposable graphs
, 2007 When considering a graphical Gaussian model ${\mathcal{N}}_G$ Markov with respect to a decomposable graph $G$, the parameter space of interest for the precision parameter is the cone $P_G$ of positive definite matrices with fixed zeros corresponding to ...

Steiner Triple Systems With High Discrepancy
Journal of Combinatorial Designs, EarlyView.ABSTRACT In this paper, we initiate the study of discrepancy questions for combinatorial designs. Specifically, we show that, for every fixed r ≥ 3 $r\ge 3$ and n ≡ 1 , 3 ( mod 6 ) $n\equiv 1,3\,(\mathrm{mod}\,6)$, any r $r$‐colouring of the triples on [ n ] $[n]$ admits a Steiner triple system of order n $n$ with discrepancy Ω ( n 2 ) ${\rm{\Omega }}({

Last‐minute coordination: Adapting to demand to support last‐mile operations
Journal of Operations Management, Volume 71, Issue 2, Page 176-194, March 2025.Abstract In the highly competitive e‐commerce industry, customer‐facing warehouses are crucial as the “order penetration points” for e‐commerce last‐mile operations. This research examines how warehouses use last‐minute coordination, an unstructured mechanism, to ensure sufficient inventory at the order penetration points. Previous research has focused

Linear conic formulations for two-party correlations and values of nonlocal games
, 2016 In this work we study the sets of two-party correlations generated from a Bell scenario involving two spatially separated systems with respect to various physical models.

Mathematical Methods in the Applied Sciences, EarlyView.ABSTRACT The paper proposes a variational analysis of the 1‐hypergeometric stochastic volatility model for pricing European options. The methodology involves the derivation of estimates of the weak solution in a weighted Sobolev space. The weight is closely related to the stochastic volatility dynamic of the model.

Multiphysics Metamaterials for Unified Control of Diverse Physical Fields
Small Structures, EarlyView.Multiphysics metamaterials unify diffusion, wave, and hybrid field control in one architecture. This review systematically examines the design methodologies, functional implementations, and material compositions of these three categories, followed by a critical analysis of their respective advantages, limitations, and future development trends ...

Structural Concrete, EarlyView.Abstract Gerber half‐joints, broadly used in the last century as elements of concrete bridges, are prone to corrosion‐induced deterioration, which may lead to brittle shear collapse. It is of paramount importance to develop advanced numerical models for simulating the collapse behavior of Gerber half‐joints, taking material deterioration into account ...
