In the isostructural oxides Ca3CoMO6 (M = Co, Rh, Ir), the CoMO6 chains made up of face-sharing CoO6 trigonal prisms and MO6 octahedra are separated by Ca atoms. We analyzed the magnetic and electronic properties of these oxides on the basis of density functional theory calculations including on-site repulsion and spin-orbit coupling, and examined the essential one-electron pictures hidden behi...

Structural relaxation of amorphous materials is usually described as resulting from the contribution of microscopic transitions covering a spectrum of activation energies, gðEÞ [1,2]. When gðEÞ is flat, the relaxation kinetics follows a logðtÞ dependence [2,3]. Thus, it is quite surprising that Knoll et al. [4] do not rely on this classic model to describe their experimental results. Their mode...

Using a 281 pb data sample collected at the ψ(3770) with the CLEO-c detector, we present the first absolute branching fraction measurement of the decay D → Kππeνe at a statistical significance of about 4.0 standard deviations. We find 10 candidates consistent with the decay D → Kππeνe. The probability that a background fluctuation accounts for this signal is less than 4.1 × 10. We find B(D0 → K...

An exact solution, in which a D2-brane and an anti-D2-brane are bridged with a band of D0-charged IIA superstrings, is obtained without any junction condition. In view of Born-Infeld description of a D-brane, the connecting band of D0-charged superstrings can be “blown-up” to an elliptically tubular D2-brane, which makes the whole system perfectly (1/4)-supersymmetric. It is shown that D0-charg...

We consider a matrix model composed of three parts: the dimensionally reduced Yang-Mills terms, d = 1 Chern-Simons term and a kinetic term for a bosonic vector field as introduced by Polychronakos recently. The coefficient, κ of the Chern-Simons term is integer, and hence the level structure. We show at the bottom of the YangMills potential, the low energy limit, only the linear motion is allow...

Statistical analysis of art, particularly of the abstract genre, is becoming an increasingly important tool for understanding the image creation process. We present a multifractal clustering analysis of non-representational images painted by adults and children using a ‘pouring’ technique. The effective dimensions (D0) are measured for each, as is the associated multifractal depth ΔD = D0 D∞. I...

The additional regularity conditions required for consistency are stated in Hansen’s Theorem 2.1. It follows from assumption 3 that a T a:s: ! a 0 = D0 0W 0 . De…ne h 0(b ) = a 0[E(R) D0b ]. Given that D0 has full column rank and W 0 is positive de…nite, the function h 0(b ) has a unique zero, b z = (D 0 0W 0D0) D0 0W 0E(R ). Since the model is true E(R) = D0b 0. Substituting this into the expr...

We present experimental results on b-hadron mass measurements and b-meson oscillations based on integrated luminosity of 250 to 450 pb −1 of p¯ p collisions at √ s = 1.98 TeV by the CDF and D0 collaborations at the TeVatron. The masses of b-hadrons have been measured precisely by the CDF collaboration in decays containing a J/ψ. A blind search of the decay mode Bc → J/ψπ + resulted in a peak of...

We study lifetimes of heavy mesons in the 't Hooft model, a large-Nc theory strong interaction two-dimensional spacetime. Since this model is solvable, one can evaluate total decay widths through hadronic amplitudes that are determined unambiguously within formalism. investigate quark-hadron duality by numerically comparing exclusive result and from quark expansion, with contribution Pauli inte...
