In mathematical chemistry, a particular attention is given to degree-based graph invariant. The Zagrebpolynomial is one of the degree based polynomials considered in chemical graph theory. A dendrimer isan artificially manufactured or synthesized molecule built up from branched units called monomers. Inthis note, the first, second and third Zagreb poly...

Background: Job performance is one of the most fundamental concepts in organizations, based on which, the responsibilities and success of each individual in the organization are formed.  The main objective of the current study was to investigate the mediating role of perceived organizational support in the relationship between sense of coherence (SOC) and professional ethics, and the job perfor...

previous research has identified the nominal group as the most distinctive feature of the research article title. in contrast, the findings reported in this paper suggest theme/rheme is the dominant structure in title text. theme/rheme structures order and tie nominal groups in titles. when a title starts with a methodological term the first position nominal group acts as a theme marker. thus, ...

This paper presents a view based approach to map learning and nav igation in mazes By means of graph theory we have shown that the view graph is a su cient representation for map behaviour such as path planning A neural network for unsupervised learning of the view graph from sequences of views is constructed We use a modi ed Kohonen learning rule that transforms temporal sequence rather than f...

Coherence that ties sentences of a text into a meaningfully connected structure is of great importance to text generation and translation. In this paper, we propose a topic-based coherence model to produce coherence for document translation, in terms of the continuity of sentence topics in a text. We automatically extract a coherence chain for each source text to be translated. Based on the ext...

We study the extraction and visualization of brain connectivity networks from EEG and fMRI data. The method is based upon the construction of functional unit maps. It is indicated how this representation can be used for comparing brain networks in the original network representation. INTRODUCTION Various types of brain connectivity are distinguished. Structural or anatomical connectivity refers...

It has long been recognized that the concept of inconsistency is a central part of commonsense reasoning. In this issue, a number of authors have explored the idea of reasoning with maximal consistent subsets of an inconsistent stratified knowledge base. This paradigm, often called “coherent-based reasoning", has resulted in some interesting proposals for paraconsistent reasoning, non-monotonic...
