we study local stability of self-gravitating fluid and stellar disk in the context of modified gravity theories which predict a yukawa-like term in the gravitational potential of a point mass. we investigate the effect of such a yukawa-like term on the dynamics of self-gravitating disks. more specifically, we investigate the consequences of the presence of this term for the local stability of t...

green space, as a social development indicator has environmental, social, cultural, economical, and skeletal aspects and to be able to play its role effectively, the first and most important step is to select an appropriate site for it. site selection necessitates stability analysis of urban green space. the main three steps are identifying stability factors, ahp-based weighting factors and lay...

The Disease Control Priorities (DCP) publications have pioneered new ways of thinking about investing in health. We agree with Norheim, that a useful first step to advance efforts to translate DCP’s global evidence into local health priorities, is to develop a clear Theory of Change (ToC). However, a ToC that aims to define how global evidence (DCP and others) can be used to inform national pol...

Background: Attention impairments are the hallmark feature of subclinical depression. The present study used Navon task to compare the allocation of attention to the local and global stimuli in depressed and nondepressed participants. Method: The primary sample included 186 female high school students from Shiraz city who were selected using cluster sampl...

Background: The link prediction issue is one of the most widely used problems in complex network analysis. Link prediction requires knowing the background of previous link connections and combining them with available information. The link prediction local approaches with node structure objectives are fast in case of speed but are not accurate enough. On the other hand, the global link predicti...
