For a differential graded k-quiver Q we define the free A∞-category FQ generated by Q. The main result is that the restriction A∞-functor A∞(FQ,A) → A1(Q,A) is an equivalence, where objects of the last A∞-category are morphisms of differential graded k-quivers Q → A. A∞-categories defined by Fukaya [Fuk93] and Kontsevich [Kon95] are generalizations of differential graded categories for which th...

A DNMT3B (DNMT3B , DNA (cytos ine-5)methyltransferase 3B; Swiss-Prot accession number: Q9UBC3) gene deletion construct in which exons 16–19 were deleted was used to generate Dnmt3b-null ES cells and animals. The deleted region encodes the highly conserved PC (proline cysteine) and ENV (glutamic acid, asparagine, valine) motifs that are crucial for catalytic activity [1,2]. Targeted replacement ...

Mol-ecules of the title compound, C(12)H(7)NOS, with one half-mol-ecule in the asymmetric unit, are disordered about a crystallographic centre of inversion. Refinement showed that the C=O group is disordered with the S atom and the N atom is disordered over four positions. Adjacent mol-ecules are connected through C-H⋯O hydrogen bonds and π⋯π inter-actions (centroid-centroid distances of 3.635 ...

1 Introduction Conjecture 1.1 (since 1992) G ⊂ SL(n, C) is a finite subgroup. Assume that the quotient X = C n /G has a crepant resolution f : Y → X (this just means that K Y = 0, so that Y is a " noncompact Calabi–Yau manifold "). Then there exist " natural " bijections {irreducible representations of G} → basis of H * (Y, Z) (1) {conjugacy classes of G} → basis of H * (Y, Z) (2) As a slogan "...

In the mol-ecule of the title compound, C(12)H(6)N(2)O(3)S, the central heterocyclic ring is oriented at dihedral angles of 3.25 (6) and 2.28 (7)° with respect to the benzene and pyridine rings, respectively. The dihedral angle between the benzene and pyridine rings is 5.53 (7)°. In the crystal structure, inter-molecular C-H⋯O hydrogen bonds link the mol-ecules into chains.

We present recent CDF results on B lifetimes, B meson mass measurements, ratios of branching ratios, and rare decays. In addition, we present the first measurement of time-dependent Bd mixing at CDF. Several results have been updated and a few new ones included since the workshop.

In this talk, we review the QCD calculations of the lepton spectrum from inclusive semileptonic B decay. We compare this prediction to that of the ACCMMmodel. This latter work was done in collaboration with Csaba Csaki. Invited Talk, Presented at WHEPP-3 Workshop in Madras This work is supported in part by funds provided by the U.S. Department of Energy (DOE) under contract #DE-AC02-76ER03069 a...
