We present a new hybrid meta exchange-correlation functional, called M05-2X, for thermochemistry, thermochemical kinetics, and noncovalent interactions. We also provide a full discussion of the new M05 functional, previously presented in a short communication. The M05 functional was parametrized including both metals and nonmetals, whereas M05-2X is a high-nonlocality functional with double the...

L-Aspartase was purified from Bacillus subtilis, its N-terminal amino acid sequence was determined to construct a probe for the aspartase gene, and the gene (termed ansB) was cloned and sequenced. A second gene (termed ansA) was found upstream of the ansB gene and coded for L-asparaginase. These two genes were in an operon designated the ans operon, which is 80% cotransformed with the previousl...

The Hall conductivity in the magnetic-field-induced spin-density-wave (FISDW) state of the quasi-onedimensional organic conductors (TMTSF)2X at a finite temperature is calculated. The temperature dependence of the Hall conductivity is found to be the same as the temperature dependence of the Fröhlich current of a regular charge/spin-density wave. Predicted dependence σxy(T ) can be verified exp...

Abstract Garden asparagus ( Asparagus officinalis L.) is a diploid (2n = 2x 20), perennial and dioecious species belonging to subgenus worldwide cultivated as vegetable crop. A narrow genetic base has been pointed out for the current cultivars. Crop wild related (CWR) could be valuable resource in this crop but they have underused up now. To investigate phylogenetic relationships between CWR fr...

Let X be a Hausdorff continuum (a compact connected Hausdorff space). Let 2X (respectively, Cn(X)) denote the hyperspace of nonempty closed subsets of X (respectively, nonempty closed subsets of X with at most n components), with the Vietoris topology. We prove that if X is hereditarily indecomposable, Y is a Hausdorff continuum and 2X (respectively Cn(X)) is homeomorphic to 2Y (respectively, C...

Let MaxCut(G) be the value of the maximum cut of a graph G. Let f(x, n) be the expectation of MaxCut(G)/xn for random graphs with n vertices and xn edges and let r(x, n) be the expectation of MaxCut(G)/xn for random 2x-regular graphs with n vertices. We prove, for sufficiently large x: 1. limn→∞ f(x, n) ≤ 12 + √ ln 2 2x , 2. limn→∞ r(x, n) ≤ 12 + 1 √ x + 1 2 ln x x .

Melt-quenched AsxGexSe1-2x glasses over the composition range, 0 < x < 0.26, are examined in Raman scattering, T-modulated Differential Scanning Calorimetry (MDSC), and Sn Mossbauer spectroscopy measurements. The non-reversing enthalpy near Tg, ∆Hnr(x), accessed from MDSC shows a global minimum (~ 0) in the xc(1) = 0.09 < x < xc(2) = 0.16 range, and increases by an order of magnitude both at x ...

In situ hybridization of 18S-5.8S-25S rDNA probes labeled with biotin or rhodamine and 5S rDNA probes labeled with digoxigenin was used to locate rDNA sites on root-tip metaphase chromosomes of Citrus sinensis L. (2n = 2x = 18), Poncirus trifoliata L. Raf. (2n = 2x = 18), and Citrus x Poncirus hybrids (2n = 2x = 18). Counterstaining with the fluorochromes chromomycin A3 and DAPI uniquely identi...
