For a complex flat vector bundle over a fibered manifold, we consider the 1-parameter family of certain deformed sub-signature operators introduced by Ma-Zhang in [MZ]. We compute the adiabatic limit of the Bismut-Freed connection associated to this family and show that the Bismut-Lott analytic torsion form shows up naturally under this procedure.

The problem of counting unlabelled subtrees of a tree (that is, subtrees that are distinct up to isomorphism) is #P-complete, and hence equivalent in computational difficulty to evaluating the permanent of a 0,1-matrix.

Supersymmetric Grand Unified Theories have a rich spectrum of particles barely heavier than the intermediate vector bosons. As their non-supersymmetric counterparts, they lead to many relations among low energy observables. But the precise form of the predictions is modified by the extended spectrum. If the masses of these new particles are comparable to MZ , the standard computation of their e...

Children differ in their ability to learn what is taught at school. Evidence from twin studies suggests that genetic effects contribute to such differences. The aim of the present study was to systematically review the existing literature, including 61 studies from 11 cohorts, on twin studies of educational achievement in primary school children. The meta-analysis estimated heritability, based ...

We introduce the notion of a positive face structure. The positive face structures to positive-to-one computads are like simple graphs, c.f. [MZ], to free ω-categories over ω-graphs. In particular, they allow to give an explicit combinatorial description of positive-to-one computads. Using this description we show, among other things, that positive-to-one computads form a presheaf category with...

1. Shared Environments of Twins The model estimated with the 6 types of siblings assumes that shared environmental effects are the same for twins and full siblings. Since twins share the same womb and are exact contemporaries, it could be argued that the environments of twins are more similar than that of full siblings. An alternative argument is that the environments of twins, who compete for ...

The stability of the predictions of two of the standard model parameters, α3(MZ) and sin 2 θ(MZ), in a MU ∼ 4 TeV unification model is examined. It is concluded that varying the unification scale between MU ≃ 2.5 TeV and MU ≃ 5 TeV leaves robust all predictions within reasonable bounds. Choosing MU = 3.8± 0.4 TeV gives, at lowest order, accurate predictions at MZ . The impact of threshold effec...

Implications of a formal context (G,M, I) have a minimal implication basis, called Duquenne-Guigues basis or stem base. It is shown that the problem of deciding whether a set of attributes is a premise of the stem base is in coNP and determining the size of the stem base is polynomially Turing equivalent to a #P-complete problem.

The pinch technique (PT) is applied to neutral current amplitudes, focusing on the mixing problem. Extending recent arguments due to Papavassiliou and Pilaftsis, it is shown that the use of the PT self-energies does not shift the complex-valued position of the pole through order O(g). This leads (to the same accuracy) to a simple interpretation of MZ , the mass measured at LEP, in terms of the ...

This paper describes an ontology created for the RESCUER 1 (Reliable and Smart Crowdsourcing Solution for Emergency and Crisis Management), a project funded by the European Union and the Brazilian Ministry of Science, Technology and Innovation, it uses crowdsourcing information for supporting Industrial Parks (InPa) and Security Forces during an emergency situation. The proposal, EDXLRESCUER on...
