Let G be a finite p-group and let Aut_l(G) be the group of absolute central automorphisms of G. In this paper we give necessary and sufficient condition on G such that each absolute central automorphism of G fixes the centre element-wise. Also we classify all groups of orders p^3 and p^4 whose absolute central automorphisms fix the centre element-wise.

let be a stationary sequence of pair wise negative quadrant dependent random variables with survival function {,1}nxn?f(x)=p[x>x]. the empirical survival function ()nfx based on 12,,...,nxxx is proposed as an estimator for ()nfx. strong consistency and point wise as well as uniform of ()nfx are discussed

Existing literature supports the five-factor model (FFM) of personality (i.e., Extraversion, Agreeableness, Conscientiousness, Emotional Stability, and Intellect or Openness) as a comprehensive representation of stable aspects of mood, affect, and behavior. This study evaluated the FFM as a framework for both self-perceptions of drunkenness (i.e., individual changes in mood, affect, and behavio...

This paper utilizes the Asset and Health Dynamics of the Oldest Old (AHEAD) Panel to test for the absence of causal links from socio-economic status (SES) to innovations in health or mortality, and from health conditions to innovations in wealth. We conclude that there is no causal link from SES to mortality or to incidence of sudden onset health conditions (accidents and, probably, acute condi...

The paper reviews the Astro-WISE infrastructure and demonstrates that the Astro-WISE Information System provides a Grid itself. We describe the integration of Astro-WISE with an external Grid infrastructure (BiGGrid). The integration is performed on all infrastructural layers (data storage, metadata and processing layers) with Astro-WISE as a “master” infrastructure. We report the use of the in...
