It is a pity that the real state of matter in pulsar-like stars is still not determined confidently because of the uncertainty about cold matter at supranuclear density, even 40 years after the discovery of pulsar. Nuclear matter (related to neutron stars) is one of the speculations for the inner constitution of pulsars even from the Landau’s time more than 70 years ago, but quark matter (relat...

We have studied the effect of hypothetical Cosmions on the core stability of main sequence stars (of populations I and II). Cosmions, with a mass of 4-10 Gev/c2 and a scattering cross section with nucleons of approximately 10-36 cm2 could prevail in transporting heat in the stellar cores. Raby [17] showed the existence of a local thermal instability caused by the presence of Cosmions in the sol...

Rivers have a symbolic meaning in the work of Levan Gotua. As writer thinking about fate nation, he looks at river with this eye, is an integral part history, witness to country. The presents Alazani not only figuratively, but also kind conceptual line that adds new color mother „Gmirta Varami“, on other hand, and floodplains are main places Gotua's series essays – „Mgzavruli Krialosani“, where...

Mobile household robots need much knowledge about objects, places and actions when performing more and more complex tasks. They must be able to recognize objects, know what they are and how they can be used. This knowledge can often be specified more easily in terms of actionrelated concepts than by giving declarative descriptions of the appearance of objects. Defining chairs as objects to sit ...

We report on searches for radio emission from three of the nearest known young brown dwarfs using the Very Large Array. We have obtained sensitive upper limits on 3.6cm emission from 2MASSW J1207334-393254, TWA 5B and SSSPM J1102-3431, all of which are likely members of the ∼8-Myr-old TW Hydrae association. We derive constraints on the magnetic field strength and the number density of accelerat...

We introduce the Deep Symbolic Network (DSN) model, which aims at becoming the white-box version of Deep Neural Networks (DNN). The DSN model provides a simple, universal yet powerful structure, similar to DNN, to represent any knowledge of the world, which is transparent to humans. The conjecture behind the DSN model is that any type of real world objects sharing enough common features are map...

We present results of X-ray spectral and timing analyses of solar-like (spectral types F5–K8) and intermediate-type (B4–F4) Pleiads observed in a 40-ks XMM-Newton EPIC exposure, probing X-ray luminosities (L X) up to a factor 10 fainter than previous studies using the ROSAT PSPC. All 8 solar-like members have " quasi-steady " L X > ∼ 10 29 erg s −1 consistent with the known rotation–activity re...

Cognitive Architectures (CAs) are the core of artificial cognitive systems. A CA is supposed to specify the human brain at a level of abstraction suitable for explaining how it achieves the functions of the mind. Over the years a number of distinct CAs have been proposed by different authors and their limitations and potentials were investigated. These CAs are usually classified as symbolic and...
