A double Roman dominating function on a graph G=(V,E) is f:V?{0,1,2,3} satisfying the condition that every vertex u for which f(u)=0 adjacent to at least one assigned 3 or two vertices 2, and with f(u)=1 2 3. The weight of f equals w(f)=?v?Vf(v). domination number ?dR(G) G minimum G. We obtain closed expressions generalized Petersen graphs P(5k,k). It proven ?dR(P(5k,k))=8k k?2,3mod5 8k??dR(P(5...

This paper describes a new approach to language model adaptation for speech recognition based on the statistical framework of speech translation. The main idea of this approach is to compose a weighted finite-state transducer (WFST) that translates sentence styles from in-domain to out-of-domain. It enables to integrate language models of different styles of speaking or dialects and even of dif...

We report a study of the magnetoresistance (MR) of the metallic perovskite oxide LaNiO3−δ as a function of the oxygen stoichiometry δ (δ ≤ 0.14), magnetic field ( H ≤ 6T ) and temperature (1.5K ≤ T ≤ 25K). We find a strong dependence of the nature of MR on the oxygen stoichiometry. The MR at low temperatures change from positive to negative as the sample becomes more oxygen deficient ( i.e, δ i...

The first definite discoveries of extragalactic deuterium are reported. DCO has been detected in three and DCN has been measured in one star-forming region of the Large Magellanic Cloud (LMC). While the HCO/DCO abundance ratios are found to be 19± 3, 24 ± 4, and 67 ± 18 for N113, N44BC and N159HW, respectively, a HCN/DCN abundance ratio of 23 ± 5 is obtained for N113. These results are consiste...

We report bulk 4f and non-4f spectral functions near the Fermi level (EF) of a Kondo semiconductor CeRhAs and its related compound CePdSn by virtue of high-resolution soft X-ray photoemission. The non-4f spectrum of CeRhAs measured at 20K shows a shoulder at the binding energy of 0:18 eV and almost negligible spectral weight at EF: Although a peak similar to a tail of the Kondo resonance is obs...

The Chinese hamster lung cell line DC-3F contains two polymorphic di hydro l'oliile reducÃ-ase (DHFR) alÃ-elesthai are defined by an Asp-Asn amino acid sequence difference al posilion 95 in Ihe prolein. Previously, we reported thai Ihe anlifolale-resistant subline DC-3F/A3 overexpressed a I cu.* -»Phe mulanl of Ihe Asp95 (21k) alÃ-eleand that this was Ihe basis of its resistance to melholrexal...
