The potential energy surfaces of the group 17 XF3 (X = Cl, Br, I, At) fluorides have been investigated for the first time with multiconfigurational wave function theory approaches. In agreement with experiment, bent T-shaped C(2v) structures are computed for ClF3, BrF3, and IF3, while we predict that an average D(3h) structure would be experimentally observed for AtF3. Electron correlation and ...

The decay rate of the 2v double beta decay is calculated. The effects of pairing, static quadrupole deformation, spin-isospin polarization, and the .6.33 isobar admixtures on the nuclear matrix elements are studied and the relation of the 2v {3{3 rate and the {3and f3+ strength is stressed. In agreement with other calculations, we predict a faster decay rate than has been observed experimentall...

Let a = a[1..2v] be a word which is a square and for which a[1..2u] is also a square and a[k + 1..min(k + 2w, 2v)] has period w where u < w < v < 2u and 0 ≤ k ≤ v − u. We show that under certain extra conditions on k and w the word has period gcd(u, v, w) and describe the word’s structure when these extra conditions do not hold. c © 2006 Elsevier B.V.

BACKGROUND AND OBJECTIVE Children with congenital heart disease (CHD) are at risk for developmental delay (DD). Changes in cognitive, language, and motor skills in early childhood have not been described. We report the results of a structured approach using longitudinal testing to identify problems and ensure early intervention in accordance with published guidelines. METHODS Bayley Scales of...

The nectin and nectin-like molecule (Necl) family includes important cell adhesion molecules (CAMs) characterized by their Ig-like nature. Such CAMs regulate a broad spectrum of cell-cell interactions, including the interaction between NK cells and cytotoxic T lymphocytes (CTLs) and their target cells. CAM members nectin-2 (CD112) and Necl-5 (CD155) are believed to form homodimers (for nectin-2...

The purpose of this study was to evaluate the regional bond strength of a dual-cure resin core material to root canal dentin using four self-etching primer/adhesive systems. Post spaces were prepared in extracted premolars, and their root canal dentin was treated with one of the following self-etching primer/adhesive systems: ED Primer II and Clearfil Photobond, photo-cure/dual-cure systems of ...

We obtain explicit formulae for the values of the 2v − j minors, j = 0, 1, 2, of Doptimal designs of order 2v = x2 + y2, v odd, where the design is constructed using two circulant or type 1 incidence matrices of 2−{2s2+2s+1; s2, s2; s(s−1)} supplementary difference sets (sds). This allows us to obtain information on the growth problem for families of matrices with moderate growth. Some of our t...

and Applied Analysis 3 It follows from 2.1 and 2.6 that 2f ( x y 2 ) − g x − h(y) 2f ( x y 2 ) − g(y z) − h x − z − [ 2f (x z 2 ) − g 2z − h x − z ] [ 2f ( y 2z 2 ) − g 2z − h(y) ] − [ 2f ( y 2z 2 ) − g(y z) − h z ] [ 2f (x z 2 ) − g x − h z ] ∈ 3V − 2V 2.7 for all x, y ∈ X with ‖x‖ ‖y‖ < d. Hence, by 2.1 and 2.7 , we have 2f ( x y 2 ) − g x − h(y) ∈ 3V − 2V 2.8 for all x, y ∈ X. Letting x 0 y ...

Unrestricted density functional theory (UB3LYP), CASSCF, and CASPT2 calculations have been employed to compute the relative energies of the C(s) and C(2v) geometries of several 1,5-disubstituted semibullvalenes. Substitution at these positions with R = F, -CH(2)-, or -O- affords semibullvalenes that are predicted to have C(2v) equilibrium geometries. Calculated singlet-triplet energy splittings...
