Suppose that the vertex set of a connected graph G is $$V(G)=\{v_1,\ldots ,v_n\}$$ . Then we denote by $$Tr_{G}(v_i)$$ sum distances between $$v_i$$ and all other vertices G. Let Tr(G) be $$n\times n$$ diagonal matrix with its (i, i)-entry equal to $$Tr_{G}(v_{i})$$ D(G) distance $$Q_{D}(G)=Tr(G)+D(G)$$ signless Laplacian The largest eigenvalues $$Q_D(G)$$ called spectral radius In this ...

Cells exposed to acoustic cavitation and other mechanical stresses can be transiently permeabilized to permit intracellular uptake of molecules, including drugs, proteins, and genes. Microscopic imaging and other studies suggest that intracellular loading occurs through plasma membrane wounds of submicrometer radius that reseal over time through the aggregation and fusion of lipid vesicles traf...

Introduction: As a carrier of different sensors, moles can penetrate into the regolith automatically and keep investigating the subsurface environment continuously. In this section, features of several moles with different applications are introduced to explain why we choose a hammer-driven mole to study. Mole driven by a hammer: In this section, the penetrating principle of a hammer-driven mol...

The idea of automatic generation of data entry forms based on data relational models is a common and known idea that has been discussed day by day more than before according to the popularity of agile methods in software development accompanying development of programming tools. One of the requirements of the automation methods, whether in commercial products or the relevant research projects, ...

Deep drawing process is one of the most applicable methods in producing industrial parts. In this process, the initial blank deforms to final product using a rigid punch and die. In this investigation, the effect of deep drawing process parameters of brass/steel laminated sheet composites on required forming force has been investigated. The process simulated using finite element method (FEM) an...

For certain database tasks that require great exibility, some people are turning to a new kind of data representation in which the database is not constrained by a schema. Instead, each component of the database carries its own description, which is independent of other components. Systems like ACeDB, which has become very popular with biologists, and the recent Tsimmis proposal for data integr...

This paper deals with the threshold radius that warrants the use of single restraining rail for transit and railroads. Different railways use different threshold radius from 91m to 365m to provide restraining rail. These threshold figures are probably experience driven choices. The need for restraining rail may be related to a so-called derailment alarm coefficient of 1.2 sustained over 2m leng...

background: mal::::union:::: is the most common complication following distal radius fractures. aim of this study was to evaluate the results of distal radius corrective osteotomy and plate fixation by dorsal approach in the mal::::union::::. methods: in this retrospective study, 14 patients with neglected distal radius mal::::union:::: from 2005 to 2011 were studied. all patients were treated ...

the average distance of a vertex $v$ of a connected graph $g$is the arithmetic mean of the distances from $v$ to allother vertices of $g$. the proximity $pi(g)$ and the remoteness $rho(g)$of $g$ are defined as the minimum and maximum averagedistance of the vertices of $g$. in this paper we investigate the difference between proximity or remoteness and the classical distanceparameters diameter a...
