Rockburst management in Canadian hard rock mines
Rockburst is a complex mining-induced phenomenon that remains difficult to be quantified. In particular, geological conditions contributing to rockbursts are more variable than those in many conventional engineering approaches.

Precise determination of the Higgs mass in supersymmetric models with vectorlike tops and the impact on naturalness in minimal GMSB [PDF]
We present a precise analysis of the Higgs mass corrections stemming from vectorlike top partners in supersymmetric models. We reduce the theoretical uncertainty compared to previous studies in the following aspects: (i) including the one-loop threshold ...

On the equivariant Tamagawa number conjecture for Tate motives and unconditional annihilation results [PDF]
Let L/K be a finite Galois extension of number fields with Galois group G. Let p be a rational prime and let r be a non-positive integer. By examining the structure of the p-adic group ring Z_p[G], we prove many new cases of the p-part of the equivariant

Inhomogeneous phases in the Nambu-Jona-Lasino and quark-meson model
We discuss inhomogeneous ground states of the Nambu-Jona-Lasino (NJL) and quark-meson (QM) model within mean-field approximation and their possible existence in the respective phase diagrams. For this purpose we focus on lower dimensional modulations and
