Automated beat tracking and tempo estimation from music recordings become challenging tasks in the case of nonpercussive music with soft note onsets and time-varying tempo. In this paper, we introduce a novel mid-level representation which captures predominant local pulse information. To this end, we first derive a tempogram by performing a local spectral analysis on a previously extracted, pos...

Spacetime properties of the tachyon of the p-adic string theory can be derived from a (non-local) action on the p-adic line Qp, thought of as the boundary of the ‘worldsheet’. We show that a term corresponding to the background of the antisymmetric second rank tensor field B can be added to this action. We examine the consequences of this term, in particular, its relation to a noncommutative de...

We show that the geometric part of the abelian étale fundamental group of a proper smooth variety over a local field is finitely generated over b Z with finite torsion, and describe its rank by the special fiber of the Néron model of the Albanese variety. As an application, we complete the class field theory of curves over local fields developed by S. Bloch and S. Saito, in which the theorem co...

For a prime p, a proper subgroup H of the finite group G is strongly p-embedded in G if p divides |H| and p does not divide |H ∩ H| for all g ∈ G \H . A characteristic property of strongly p-embedded subgroups is that NG(X) ≤ H for any non-trivial p-subgroup X of H . Strongly p-embedded subgroups appear in the final stages of one of the programmes to better understand the classification of the ...
