We used the Space Fortress videogame, originally developed by cognitive psychologists to study skill acquisition, as a platform to examine learning-induced plasticity of interacting brain networks. Novice videogame players learned Space Fortress using one of two training strategies: (a) focus on all aspects of the game during learning (fixed priority), or (b) focus on improving separate game co...

In 1520, Segovia's rebel city council besieged the impregnable royal fortress located on a narrow stone outcrop at far west of city. The cathedral stood just in front fortress, and rebels demolished part church's structure to use it as secure stronghold. Beyond physical damage, revolt demonstrated peril posed by proximity castle. Unsurprisingly, was soon decided that would be relocated city's m...

Archaeological sites of Baikal region have rich collections canid remains. By the Iron Age dogs become abundant in some Transbaikalia archaeological sites, especially Xiongnu complexes. Ivolginsk Fortress is one Transbaikalia's most important where a dog first (in faunal 1955–1974 excavations) and fourth collection 2017 excavation) numerous among domestic animals. However, remains from site are...

T h e AMIA off ice has announced plans for not only a swimming meet, but also an AMIA cross-country meet. The cross-country meet, which will be run on a two-mile course, is open to both team (five men) and individual competition. Team points will be scored on the basis of the total for the Ave finishers. The team with the low score wins. The first five finishers will receive medals, while place...

We construct a continuous semigroup of weak, dissipative solutions to a nonlinear partial differential equations modeling nematic liquid crystals. A new distance functional, determined by a problem of optimal transportation, yields sharp estimates on the continuity of solutions with respect to the initial data. 1 Introduction In this paper we investigate the Cauchy problem

The quark condensate which enters the Gell-Mann-Oakes-Renner (GMOR) relation, is investigated in the framework of one-gluon-exchange models. The usual definition of the quark condensate via the trace of the quark propagator produces a logarithmic divergent condensate. In the product of current mass and condensate, this divergence is precisely compensated by the bare current mass. The finite val...

In the current thesis, the extent to which the A3C architecture is able to learn higher-order control tasks is studied. The tasks consisted of a set of subtasks of the simplified Space Fortress game which vary in complexity and order of control required. Experiments in previous attempts with Deep Q-learning applications on these subtasks have shown substantial learning in the lower-order tasks,...
