In this paper we develop an analog of the notion of the con- jugacy graph of  nite groups for the  nite semigroups by considering the Green relations of a  nite semigroup. More precisely, by de ning the new graphs $Gamma_{L}(S)$, $Gamma_{H}(S)$, $Gamma_{J}(S)$ and $Gamma_{D}(S)$ (we name them the Green graphs) related to the Green relations L R J H and D of a  nite semigroup S , we  first atte...

We present an implementation of a discourse parsing system for a lexicalized Tree-Ajoining Grammar for discourse, specifying the integration of sentence and discourse level processing. Our system is based on the assumption that the compositional aspects of semantics at the discourse-level parallel those at the sentence-level. This coupling is achieved by factoring away inferential semantics and...

Rolandi A search for non-resonant D(s) → π+μ+μ− and D(s) → π−μ+μ+ decays is performed using proton– proton collision data, corresponding to an integrated luminosity of 1.0 fb−1, at √ s = 7 TeV recorded by the LHCb experiment in 2011. No signals are observed a...

The Sis111d-s7 3 7d surface is one of the most, if not the most, complicated surface structure in existence. A mystery for many years, the first reasonably accurate structure model came from transmission electron diffraction data (TED) [1,2], assisted in part by the observation of adatoms by scanning tunneling microscopy (STM) [3–6]. The results of grazing incidence x-ray diffraction [7–9], low...
