We explore building generative neural network models of popular reinforcement learning environments. Our world model can be trained quickly in an unsupervised manner to learn a compressed spatial and temporal representation of the environment. By using features extracted from the world model as inputs to an agent, we can train a very compact and simple policy that can solve the required task. W...

We paste together patches of AdS6 to find solutions which describe two 4-branes intersecting on a 3-brane with non-zero tension. We construct explicitly brane arrays with Minkowski, de Sitter and Anti-de Sitter geometries intrinsic to the 3-brane, and describe how to generalize these solutions to the case of AdS4+n, n > 2, where n n + 2-branes intersect on a 3-brane. The Minkowski and de Sitter...

The combination of powerful mobile devices and the connective potential of cloud-based computing are changing how, where, and when people use computers. No longer physically tethered, computers embedded in mobile phones and tablets freely roam in daily life with their human users while persistently connected to the network. At the same time, the pervasiveness of computing is enabling us to enga...

I am afraid of fire because of the sadistic ringmaster at the circus always whipping me with a fire whip. I also trust those who have been nice to me, such as all of the group I travel with. I trust Zuko after he frees me from captivity. I can become quite temperamental towards anyone who I think is a threat to myself or my friends, especially Aang. Conversely, I have demonstrated an unrestrain...

majority of practical terms in ophthalmology were compiled firstly in muslims` medical dictionary. anatomical and pathological terms such as retina and cataract were improved in this lexicon. mohammad ghazi, in journal of azziae, has considered ophthalmology as an innovation which was firstly introduced by muslim arabs. their attempts promoted this science and retained it the best for a long ti...

lead is a relatively ubiquitous heavy metal with particular features such as resistance to corrosion, high malleability and wide variety of industrial applications. in medicine, however, it is considered as a slow-acting toxic substance affecting multiple body systems, specifically functioning as a potent neurotoxin in the central nervous system. lead poisoning may be acute or chronic and can b...

in the present study, competitiveness of iranian pistachio exports and competitor countries in  the world market are studied. pistachio export advantage using indices of revealed comparative advantage (rca) approach and vector error correction model(vecm) based on  agricultural and non-petroleum export commodity basket were investigated separately. the results showed that iran has a comparative...
