In the past decade, research on network data has attracted much attention and many interesting phenomena have been discovered. Such data are often characterized by high dimensionality but how to select meaningful and more succinct features for network data received relatively less attention. In this paper, we investigate unsupervised feature selection problem on networks. To effectively incorpo...

This paper challenges the prevailing pessimism about the scale-up ability of partial order planners (POP) by presenting several novel heuristic control techniques that make the PO planners competitive with the state of the art plan synthesis algorithms. Our critical insight is that the techniques responsible for the efficiency of the currently successful planners–viz., distance based heuristics...

Like many art therapists, I spent the past year offering therapy in a way that was new to me—virtually. Given my appreciation for 1980s pop culture, it took me little while get over feelin...

We present general properties of ionized hydrogen (HII) bubbles and their growth based on a stateof-the-art large-scale (100 Mpc/h) cosmological radiative transfer simulation. The simulation resolves all halos with atomic cooling at the relevant redshifts and simultaneously performs radiative transfer and dynamical evolution of structure formation. Our major conclusions include: (1) for signifi...

The presence of different pollutants in recycled plastics is reviewed this article. desirable circular economy should be linked to the availability clean with a non-significant and small nil amount substances concern. Different researchers found polycyclic aromatic hydrocarbons (PAHs) Persistent Organic Pollutants (POPs), such as brominated flame retardants (BFRs), pesticides, dioxins furans (P...
