In this paper, we study matching integral graphs of small order. A graph is called matching integral if the zeros of its matching polynomial are all integers. Matching integral graphs were first studied by Akbari, Khalashi, etc. They characterized all traceable graphs which are matching integral. They studied matching integral regular graphs. Furthermore, it has been shown that there is no matc...

schema matching is a critical step in many applications, such as data warehouse loading, online analytical process (olap), data mining, semantic web [2] and schema integration. this task is defined for finding the semantic correspondences between elements of two schemas. recently, schema matching has found considerable interest in both research and practice. in this paper, we present a new impr...

BACKGROUND Only in a few longitudinal studies it has been examined whether job resources should be matched to job demands to show stress-buffering effects of job resources (matching hypothesis), while there are no empirical studies in which the moderating effect of matching personal characteristics on the stress-buffering effect of job resources has been examined. PURPOSE In this study, both ...

Many species of territorial songbirds exhibit a behavior known as song-type matching, in which a male sings the same song type that his neighbor is singing. Song-type matching is associated with increased aggression, but researchers have not come to a consensus on its adaptive function. Building on studies that identify singing performance as a variable relevant to sexual selection, we hypothes...

Two-level models are widely used for analysing clustered survey data with the design structure matching model hierarchy. Hypothesis testing on parameters is studied, using a weighted composite likelihood approach that takes account of features. In particular, asymptotic normality estimators established. Using this result, distributions generalised score test statistic and ratio type statistic, ...

Drawing on two assumptions: that menopause is an instrument for the efficient regulation of duration a biologically expensive state, and people have children in order to obtain support from them old age, we set out new idea seeks explain both occurrence its timing. On basis notion purpose having perceive as upper limit fertile when continued ability give birth would not generate desired support...
