Non-topological solitons are localized classical field configurations stabilized by a Noether charge. Friedberg, Lee, and Sirlin proposed simple renormalizable soliton model in their seminal 1976 paper, consisting of complex scalar that carries the charge real-scalar mediator. We revisit this model, point out commonalities differences with Q-ball solitons, provide analytic approximations to und...

Kurzfassung Die Tendenz hin zu kundenorientierten Geschäftsmodellen führt insbesondere bei Finanzdienstleistern zu steigenden Investitionen in IT im Bereich Customer Relationship Management. Vor dem Hintergrund, dass ein Großteil dieser Investitionen nicht den erhofften Erfolg bringt, wird die Notwendigkeit einer ex ante Bewertung von IT-Investitionen in diesem Bereich deutlich. Deshalb wird im...

This paper describes the IBM approach to Broadcast News Transcription. Typical problems in the Broadcast News Transcription task are segmentation, clustering, acoustic modeling, language modeling and acoustic model adaptation. This paper presents new algorithms for each of these focus problems. Some key ideas include Bayesian Information Criterion (for segmentation, clustering and acoustic mode...

We study the relativistic Lee model on static Riemannian manifolds. The model is constructed nonperturbatively through its resolvent, which is based on the so-called principal operator and the heat kernel techniques. It is shown that making the principal operator well-defined dictates how to renormalize the parameters of the model. The renormalization of the parameters are the same in the light...

We present the diametric theorem for additive anticodes with respect to the Lee distance in Zn2k , where Z2k is an additive cyclic group of order 2. We also investigate optimal anticodes in Znpk for the homogeneous distance and in Zm for the Krotov-type distance.

neither damage mechanics model nor elastoplastic constitutive law can solely describe the behavior of concrete satisfactorily. in fact, they both fail to represent proper unloading slopes during cyclic loading. to overcome the disadvantages of pure plastic models and pure damage approaches, the combined effects need to be considered. in this regard, various classes of plastic-damage models have...
