We consider the future dynamics of a transient phantom dominated phase of the universe in LQC and in the RS braneworld, which both have a non-standard Friedmann equation. We find that for a certain class of potentials, the Hubble parameter oscillates with simple harmonic motion in the LQC case and therefore avoids any future singularity. For more general potentials we find that damping effects ...

Energy carriers are one of the most important inputs in the agricultural sector. These inputs have been the foundation of the development and transition of the agricultural sector from the traditional stage to the industrial stage. The energy per capita marginal consumption in Iran’s agricultural sector is 3.2 times greater than its global average. Therefore, it is essential to save and optimal...

Roughly half of all ganglion cells in mammalian retina belong to the broad class, termed "sluggish." Many of these cells have small receptive fields and project via lateral geniculate nuclei to visual cortex. However, their possible contributions to perception have been largely ignored because sluggish cells seem to respond weakly compared with the more easily studied "brisk" cells. By selectin...

Standard Phillips curve models relating price inflation to measures of slack in the economy suggest that the United States should have experienced an episode of deflation during the Great Recession and the subsequent sluggish recovery. But although inflation reached very low levels, prices continued to rise rather than fall. More recently, many observers have argued that inflation should have i...

In recent years, the notion that computers and robots will attain superhuman levels of intelligence in the next few decades, ushering in a new “posthuman” era in evolutionary history, has gained widespread attention among technology enthusiasts, thanks in part to books such as Ray Kurzweil’s The Singularity Is Near. This paper describes an introductory-level AI course designed to examine this i...

Has there been a linkage mechanism between the prices of Bitcoin and traditional wealth preservation investment tools, that is, may serve as an substitute when other tool markets are sluggish, or can also benefit from it overall market is hot. The price exhibits extremely unstable characteristics, double its value dozens times in very short period time return to starting point single day. rapid...
