< π(q) D(q2)|D(q1, ǫ) >= gD∗Dπ(ǫ · q) (1) governs the decay D → Dπ; from the experimental branching ratio BR(D → Dπ) = 68.1 ± 1.0 ± 1.3 % [1] and from the measurement Γ(D) < 131 KeV [2] the upper limit gD∗Dπ ≤ 20.6 can be derived. The analogous coupling constant in theB channel, gB∗Bπ, describes the contribution of the B ∗ pole to the form factor F 1 (q ) of the semileptonic decay B → πlν:

We show that Tobin's q, as proxied by the ratio of the firm's market value to its book value, increases with the firm's systematic equity risk and falls with the firm's unsystematic equity risk. Further, an increase in the firm's total equity risk is associated with a fall in q. The negative relation between the change in total risk and the change in q is robust through time for the whole sampl...

Methane and ammonia abundances in the coma of Halley are derived from Giotto IMS data using an Eulerian model of chemical and physical processes inside the contact surface to simulate Giotto HIS ion mass spectral data for mass-to-charge ratios (m/q) from 15 to 19. The ratio m/q = 19/18 as a function of distance from the nucleus is not reproduced by a model for a pure water coma. It is necessary...

objectives: this study aimed to find the factors that affect dental esthetics and smile attractiveness in orthodontically treated patients according to laypeople’s judgment, and to determine whether there is any relationship between dental and smile esthetics. materials and methods: using the q-sort technique, 60 laypersons (30 males, 30 females) rated dental and smile photographs of 48 orthodo...

We investigate a slowly rotating black hole solution in novel Einstein-Maxwell-scalar theory, which is prompted by the classification of general theories. The gyromagnetic ratio this calculated, and it increases as second free parameter $\beta$ increases, but decreases with increasing $\gamma\equiv \frac{2 \alpha^{2}}{1+\alpha^2}$. In Einstein-Maxwell-dilaton (EMD) vanishes, $\alpha$ governing ...

The flavor anomalies reported in ${R}_{K}$, ${R}_{{K}^{*}}$, ${P}_{5}^{\ensuremath{'}}$, and $\mathcal{B}({B}_{s}\ensuremath{\rightarrow}\ensuremath{\phi}{\ensuremath{\mu}}^{+}{\ensuremath{\mu}}^{\ensuremath{-}})$ indicate lepton universality violation $b\ensuremath{\rightarrow}s{l}^{+}{l}^{\ensuremath{-}}$ quark level transition decays. deviation from the standard model prediction underlying o...

In 198 patients with acute myocardial infarction serial measurements of plasma creatine kinase isoenzyme MB (CK MB) were performed at four hour intervals. In every patient, maximal CK MB activity (peak activity) was compared with calculated total release per litre plasma. In 28 patients (group 1) sufficient plasma samples were available for calculation of the apparent first order inactivation c...
