Reformulated First Zagreb Index of Some Graph Operations

Mathematics, 2015
The reformulated Zagreb indices of a graph are obtained from the classical Zagreb indices by replacing vertex degrees with edge degrees, where the degree of an edge is taken as the sum of degrees of the end vertices of the edge minus 2. In this paper, we

Actuation of Cell Layers in Three Dimensions

Advanced Materials, EarlyView.
ABSTRACT The alignment of fibers and cells in living tissues affect their mechanical properties and functionality. In this context, one can draw an analogy between tissues and nematic liquid crystal elastomers. We explore this analogy by growing fibroblasts on 2D‐patterned substrates and observing the contraction of cell sheets upon detachment from the

Weak In‐Plane Ferromagnetism and Electronic Nematicity in the Distorted Triple‐Q Magnetic Phase of Co1/3TaS2

Advanced Materials, EarlyView.
Co1/3TaS2${\rm Co}_{1/3}{\rm TaS}_{2}$ hosts a triple‐Q noncoplanar antiferromagnetic state with coexisting Z3${\rm Z}_3$ electronic nematicity. We report rotational hysteresis observed in both magnetoresistance and magnetic torque, revealing strongly pinned in‐plane weak ferromagnetic moments in the triple‐Q phase and the magnetism‐driven nature of ...

Component order edge connectivity, vertex degrees, and integer partitions

, 2023
Given a finite, simple graph $G$, the $k$-component order edge connectivity of $G$ is the minimum number of edges whose removal results in a subgraph for which every component has order at most $k-1$.

Coauthor prediction for junior researchers [PDF]

, 2013
Research collaboration can bring in different perspectives and generate more productive results. However, finding an appropriate collaborator can be difficult due to the lacking of sufficient information.

On the minimum reformulated Albertson Index of fixed-order trees and unicyclic graphs with a given maximum degree

AKCE International Journal of Graphs and Combinatorics
The Albertson index [Formula: see text], traditionally based on vertex degrees, is defined as the sum of the absolute value of the differences in degrees between adjacent vertices.

Theory Guided Fine‐Tune of Strain Effects in Pt Ternary Alloy via Rare Earth Templating: Achieving High Performance PEMFCs Catalysts

Advanced Materials, EarlyView.
Theory‐guided strain engineering and rare‐earth templating are combined to create Pt5(Ce)Co@Pt multilayer nanoparticles with a Pt5Co‐like sublayer that fine‐tunes *OH binding near the ORR volcano optimum. The resulting catalyst delivers exceptional mass activity and remarkable long‐term PEMFC durability, revealing a strategy for designing highly active

In Situ Regenerative Adduct Assisted p‐Type Doping of Organic Semiconductor

Advanced Materials, EarlyView.
An in situ regenerative adduct‐assisted (IRAA) doping strategy is introduced for p‐type doping of organic semiconductors. A regenerating adduct serves as the dopant, enabling highly efficient doping with a choice of counterions. The generality of this approach provides a scalable route to dope a wide range of hole‐transport materials with high thermal ...

Random Graphs' Robustness in Random Environment

Austrian Journal of Statistics, 2017
We consider configuration graphs the vertex degrees of which are independent and   follow the power-law distribution. Random graphs dynamics takes place in a random   environment with the parameter of vertex degree distribution following   uniform ...
