The dark side of curvature
Geometrical tests such as the combination of the Hubble parameter H(z) and the angular diameter distance dA(z) can, in principle, break the degeneracy between the dark energy equation of state parameter w(z), and the spatial curvature Ωk in a direct, model-independent way. In practice, constraints on these quantities achievable from realistic experiments, such as those to be provided by Baryon ...

متن کاملThe dark side of cosmology: dark matter and dark energy.
A simple model with only six parameters (the age of the universe, the density of atoms, the density of matter, the amplitude of the initial fluctuations, the scale dependence of this amplitude, and the epoch of first star formation) fits all of our cosmological data . Although simple, this standard model is strange. The model implies that most of the matter in our Galaxy is in the form of "dark...
متن کاملThe Dark Side of Leadership
44 / n recent years, business leaders have gained great popularity: Lee Iaccoca and Steven Jobs, for example, have stepped into the limelight as agents of change and entrepreneurship. But though we tend to think of the positive outcomes associated with leaders, certain risks or liabilities are also entailed. The very behaviors that distinguish leaders from managers also have the potential to pr...
متن کاملThe dark side of CIELAB
Standardized in 1976 as a uniform color space, CIELAB is extensively utilized in color science and engineering applications. CIELAB provides both a color difference formula and correlates for common perceptual descriptors of color. Deficiencies in both areas are well-known, and based on these known limitations, numerous fixes have been developed yielding alternative color difference formulae th...
