Mathematical Prediction for Geometry‐Mediated Cell 3D In‐Growth on Bone Tissue Engineering Scaffolds

open access: yesAdvanced Science, EarlyView.
This study identifies a fundamental pore size dependent pattern of three dimensional bone marrow derived mesenchymal stem cell (BMSC) infiltration within porous scaffolds, where small pores promote horizontal cellular bridging and large pores facilitate vertical migration.

On Normalized Signless Laplacian Resolvent Energy

open access: yesKragujevac Journal of Mathematics
Summary: Let \(G\) be a simple connected graph with \(n\) vertices. Denote by \(\mathcal{L}^+(G) =D(G)^{-1/2}Q(G) D(G)^{-1/2}\) the normalized signless Laplacian matrix of graph \(G\), where \(Q(G)\) and \(D(G)\) are the signless Laplacian and diagonal degree matrices of \(G\), respectively. The eigenvalues of matrix \(\mathcal{L}^+(G)\), \(2=\gamma_1^+

Laplacian coefficients of unicyclic graphs with the number of leaves and girth

open access: yes, 2013
Let $G$ be a graph of order $n$ and let $\mathcal{L}(G,\lambda)=\sum_{k=0}^n (-1)^{k}c_{k}(G)\lambda^{n-k}$ be the characteristic polynomial of its Laplacian matrix. Motivated by Ili\'{c} and Ili\'{c}'s conjecture [A. Ili\'{c}, M.

Quantitative Stain Mapping in X‐Ray Virtual Histology

open access: yesAdvanced Science, EarlyView.
Virtual histology promises 3D tissue examination without physical sectioning, yet has lacked the tissue‐specificity of conventional pathology. This work demonstrates the first quantitative three‐dimensional stain mapping at histologically relevant resolution, separating contrast agent from tissue to reveal cellular features such as nuclei. The approach

Solutions for the Problems Involving Fractional Laplacian and Indefinite Potentials

open access: yesAdvanced Nonlinear Studies, 2017
In this paper, we consider a class of Schrödinger equations involving fractional Laplacian and indefinite potentials. By modifying the definition of the Nehari–Pankov manifold, we prove the existence and asymptotic behavior of least energy solutions.

Laplacian energy of a graph

open access: yesLinear Algebra and its Applications, 2006
The authors introduce the concept of Laplacian energy of a graph \(G\) by letting \(LE(G)=\sum_{i=1}^n | \mu_i - \frac{2m}{n}| \), where \(\mu_i\), \(i=1,\dots,n\), are the eigenvalues of the Laplacian matrix of \(G\). They show that the above definition is well chosen and much in analogy with the usual graph energy \(E(G)\), which is the sum of ...
