The link surgery of $S^2\times S^2$ and Scharlemann's manifolds math.GT Fintushel-Stern's knot surgery gave many pairs of exotic manifolds, which are homeomorphic but non-diffeomorphic. We show that if an elliptic fibration has two parallel, oppositely oriented vanishing circles (for example $S^2\times S^2$ or Mats...

Deterministic endless collective evolvement in active nematics cond-mat.stat-mech cond-mat.soft We propose a simple deterministic dynamic equation and reveal the mechanism of large-scale endless evolvement of spatial density inhomogeneity in active nematic. We determine the phase regions analytically. The interplay...

Light Stop Searches at the LHC in Events with two b-Jets and Missing Energy hep-ph hep-ex We propose a new method to discover light top squarks (stops) in the co-annihilation region at the Large Hadron Collider (LHC). The bino-like neutralino is the lightest supersymmetric particle (LSP) and the lighter stop is t...

The Cosmological Constant Problem from the Point of View of String Theory hep-th The quantum field theory prediction of the cosmological constant is 120 orders of magnitude higher than the observed value. This is known as the cosmological constant problem. Here, we deal with the cosmological constant as a scalar ...

A calculus for costed computations cs.LO cs.DC We develop a version of the pi-calculus, picost, where channels are interpreted as resources which have costs associated with them. Code runs under the financial responsibility of owners; they must pay to use resources, but may profit by providing them. We provide a pr...
