GRB Spectral Hardness and Afterglow Properties [PDF]

open access: yes, 2000
A possible relationship between the presence of a radio afterglow and gamma-ray burst spectral hardness is discussed. The correlation is marginally significant; the spectral hardness of the bursts with radio afterglows apparently results from a ...

A new approach to local hardness

open access: yes, 2011
The applicability of the local hardness as defined by the derivative of the chemical potential with respect to the electron density is undermined by an essential ambiguity arising from this definition. Further, the local quantity defined in this way does

Effect of the over-ageing treatment on the mechanical properties of AA2024 aluminum alloy. [PDF]

open access: yes, 2012
The evolution of the hardness of the over-ageing AA2024 alloy scale was followed by measurements of Vickers hardness. The nanoindentation is adapted to the determination of elastoplastic properties (hardness and Young’s modulus) of the matrix and also of

Improved Hardness of Approximating Chromatic Number [PDF]

open access: yes, 2013
We prove that for sufficiently large K, it is NP-hard to color K-colorable graphs with less than 2^{K^{1/3}} colors. This improves the previous result of K versus K^{O(log K)} in Khot [14]
