Next Generation Modeling of Glioblastoma Progression: Diffusing Through Time and Brain
Annalen der Physik, EarlyView.Glioblastoma (GBM) is a fatal brain tumor that will inevitably recur following surgical resection. Early mathematical tumor growth models used the reaction‐diffusion equation to describe the proliferation and invasion of tumor spread. However, with increasingly advanced neuroimaging technology, diffusion tensor imaging data has more recently been ...

Certain Notions of Energy in Single-Valued Neutrosophic Graphs
Axioms, 2018 A single-valued neutrosophic set is an instance of a neutrosophic set, which provides us an additional possibility to represent uncertainty, imprecise, incomplete and inconsistent information existing in real situations.

Energy and Laplacian energy of unitary addition Cayley graphs
Filomat, 2019 In this paper, we obtain the eigenvalues and Laplacian eigenvalues of the unitary addition Cayley graph Gn and its complement. Moreover, we compute the bounds for energy and Laplacian energy for Gn and its complement.

Critical System Size for the Recovery of Topological Zero Modes in Finite Non‐Hermitian Systems
Annalen der Physik, EarlyView.A generalized non‐Hermitian SSH model on a topolectrical circuit reveals size‐dependent topological zero modes. Non‐Hermiticity enables exact zero‐admittance edge states at a critical system size, tunable via asymmetric coupling and gain/loss. Large impedance peaks signal these modes, offering insights for designing robust topological devices with ...

The Laplacian Energy of Conjugacy Class Graph of Some Finite Groups
MATEMATIKA, 2019 Let G be a dihedral group and its conjugacy class graph. The Laplacian energy of the graph, is defined as the sum of the absolute values of the difference between the Laplacian eigenvalues and the ratio of twice the edges number divided by the vertices ...

Vertex weighted Laplacian Energy of union of graphs [PDF]
Computer Science Journal of Moldova, 2018 The vertex weighted Laplacian energy with respect to the vertex weight $w$ of a graph $G$ with $n$ vertices is defined as ~$LE_w(G)=\sum\limits_{i=1}^n|\mu_i-\bar{w}|$, where ${{\mu }_{1}},{{\mu }_{2}},...,{{\mu }_{n}}$ are the Laplacian eigenvalues of ...

On Relation between the Kirchhoff Index and Laplacian-Energy-Like Invariant of Graphs [PDF]
Mathematics Interdisciplinary Research, 2017 Let G be a simple connected graph with n ≤ 2 vertices and m edges, and let μ1 ≥ μ2 ≥...≥μn-1 >μn=0 be its Laplacian eigenvalues. The Kirchhoff index and Laplacian-energy-like invariant (LEL) of graph G are defined as Kf(G)=nΣi=1n-11/μi and LEL(G)=Σi=1n-1

Inverting Palladium–Phosphorus Lewis Pair Formation: Phosphonium Acting as Z‐Type Ligand
Angewandte Chemie International Edition, EarlyView.A series of cationic phosphonium‐palladium(0) complexes were synthesized using an ambiphilic phosphorus‐based ligand. A strong Z‐type interaction was identified by DFT calculations (NBO, ETS‐NOCV, and QTAIM analyses), surpassing the strength of classical L‐type P─Pd bonds.

Advanced Physics Research, EarlyView.This work investigates the dynamic stability, chemical bonding and electronic properties of LaBH8 and LaBeH8 under pressure using first‐principles calculations. The authors reveal that LaBH8 contains strong covalent B–H bonds, while the Be–H bonds in LaBeH8 show ionic and covalent character. This study reveals the key chemical bonding character for the
