edge distance-balanced graphs are graphs in which for every edge $e = uv$ the number of edges closer to vertex $u$ than to vertex $v$ is equal to the number of edges closer to $v$ than to $u$. in this paper, we study this property under some graph operations.

Let G and H be connected graphs. The tensor product G + H is a graph with vertex set V(G+H) = V (G) X V(H) and edge set E(G + H) ={(a , b)(x , y)| ax ∈ E(G) & by ∈ E(H)}. The graph H is called the strongly triangular if for every vertex u and v there exists a vertex w adjacent to both of them. In this article the tensor product of G + H under some distancebased topological indices are investiga...

Let $G=(V(G),E(G))$ be a simple, finite and undirected graph of order $n$. A $k$-vertex weightings of a graph $G$ is a mapping $w: V(G) to {1, ldots, k}$. A $k$-vertex weighting induces an edge labeling $f_w: E(G) to N$ such that $f_w(uv)=w(u)+w(v)$. Such a labeling is called an {it edge-coloring k-vertex weightings} if $f_{w}(e)not= f_{w}(echr(chr(chr('39')39chr('39'))39chr(chr('39')39chr('39'...

Concurrently with the recent, rapid adoption of 3D printing technologies, online sharing of 3D-printable designs is growing equally rapidly, even though it has received far less attention. We study remix relationships on Thingiverse, the dominant online repository and social network for 3D printing. We collected data of designs published over ve years, and we nd that remix ties exhibit both hom...

Knowledge has proven to be a useful and fundamental formalism for reasoning about distributed systems. The application of this formalism, however, entails a loss of volition on the part of processes about which something is known. This loss of volition is often not appropriate in loosely coupled distributed systems. In this paper, we generalize the formal characterization of knowledge into one ...

In this article the reasons for an argument to be chosen as sentence topic are discussed. I argue that a topic expression can be prototypical or not, depending on how its thematic/semantic properties reflect humans’ preference to talk about certain things and not others. Although subjects are mostly prototypical topics, I show that a non-subject topic is prototypical with predicates that select...

The term “actors” in industrial relations gained currency in John Dunlop’s Industrial Relations Systems (1958). He proposed that three parties—employers, labor unions, and government-are the key actors in a modern industrial relations system. He also argued that none of these institutions could act in an autonomous or independent fashion. Instead they were shaped, at least to some extent, by th...

The concept of a consideration set has become a central concept in the study of consumer behavior. This paper shows that the common practice of estimating models using only the set of alternatives deemed to be in the set considered by a consumer will usually result in estimated parameters that are biased due to a sample selection effect. This effect is generic to many consideration set models a...

In this literature review, the authors suggested that three themes arose from recent vocational psychology literature promoting (a) agency in career development, (b) equity in the workforce, and (c) well‐being in work and educational settings. The authors reviewed research on career adaptability, self‐efficacy beliefs, and work volition with the goal of delineating variables that promote or con...

"We have developed a novel approach for the detection of MRI based on optical atomic magnetometry," said chemist Alexander Pines, one of the world's leading authorities on NMR/MRI technology and leader of the US Department of Energy's Lawrence Berkeley National Laboratory (Berkeley Lab) team. Pines holds a joint appointment as a chemist with Berkeley Lab's Materials Sciences Div. and with UC Be...
