Realizing the promise of 21 cm cosmology to provide an exquisite probe of astrophysics and cosmology during the cosmic dark ages and the epoch of reionization has proven extremely challenging.
As shown above, the geometry-based and geometry-free model can realize the EWL/WL AR with high single-epoch success rate, while they are still challenging for NL AR.
As with star formation noted in the STELLAR EPOCH, planet formation is a hazardous process with an unpredictable outcome a little like life in a changing, challenging environment.
Waldemar Januszczak challenges the traditional view of art's most important epoch.
Fifteen years is the cyber equivalent of a geologic epoch, because the challenges and technologies in this arena evolve almost monthly.
The existence of such massive black holes at this early epoch of the Universe challenges theories of the formation of galaxies and supermassive black holes.
The course, "Energy and environmental policy solutions for the Anthropocene," will teach students innovative energy and environmental policy solutions to address challenges of the Anthropocene — the current geological epoch typified by human dominance of the earth.
But now that the dust is beginning to settle just a little on the Jobs epoch, what exactly is his legacy and what are the principle challenges and opportunities facing Tim Cook?
Models for epoch 2010.0 were submitted in October 2009; teams therefore faced the additional challenge of how to propagate their estimates forward to 2010.0; this was not an issue faced when deriving retrospective models for epoch 2005.0.
Writing for this magazine, Elizabeth Kolbert described the challenges of trying to grasp our full impact, including "the fact that the geology of the epoch is, at this point, almost entirely prospective".
In Multi-Core Technology epoch, Network on Chip (NoC) architectures has been acknowledged as a solution to solve the design challenges of System on Chips (SoCs).
