We demonstrate that the B → D(∗)lν form factors can be accurately predicted given the slope parameter ρ2 of the Isgur-Wise function. Only weak assumptions, consistent with lattice results, on the wavefunction for the light degrees of freedom are required to establish this result. We observe that the QCD and 1 mQ corrections can be systematically represented by an effective Isgur-Wise function o...

In this work we examine user adaptation to a dialog system’s choice of realization of task-related concepts. We analyze forms of the time concept in the Let’s Go! spoken dialog system. We find that users adapt to the system’s choice of time form. We also find that user adaptation is affected by perceived system adaptation. This means that dialog systems can guide users’ word choice and can adap...

FORM AND FUNCTION IN THE HUMAN LUNG. Edited by G. Cumming and L. B. Hunt. (Pp. xi+260; illustrated, 45s.). Edinburgh & London: E. & S. Livingstone, 1968. THE Department of Medicine at Birmingham has always had a major research interest in pulmonary disease and lung function and a number of contemporary workers in this field were readily persuaded to visit Birmingham for this Symposium. They hea...

Baryon form factors can be analyzed in a largely model–independent fashion in terms of two complementary approaches. These are chiral perturbation theory and dispersion relations. I review the status of dispersive calculations of the nucleon electromagnetic form factors in the light of new data. Then, I present the leading one–loop chiral perturbation theory analysis of the hyperon and the stra...

Infiltration is the process by which water enters the earth’s surface. Although contribution of soil water to total water present on earth surface is negligible, but it is of prime importance for plant life. Very recently, dimensionless form of Kostiakov equation was proposed for precise estimation of Kostiakov model parameters. The present paper is an assessment of accuracy of proposed dimensi...

Product form Markov chains are a class of compositional Markovian models that can be proved to benefit from a decomposed solution of the steady-state distribution (i.e. the steady-state distribution is given by the product of the components’ steady-state distributions). In this paper we focus on the Boucherie product processes, a specific class of product form Continuous Time Markov Chains. We ...

A model of the electromagnetic form factor of the scalar n meson is discussed in which the n meson is a bound state of scalar nucleon-antinucleon system. Starting from an exact integral representation of the form factor, which is well defined in a space-like region of the momentum transfer squared, q2, an analytic continuation of the representation is performed under some plausible assumptions ...

This paper develops a closed-form option pricing formula for a spot asset whose variance follows a GARCH process. The model allows for correlation between returns of the spot asset and variance and also admits multiple lags in the dynamics of the GARCH process. The single-factor (one-lag) version of this model contains Heston’s (1993) stochastic volatility model as a diffusion limit and therefo...

Tolerance is essential for integration of CAD and CAM. Unfortunately, the meaning of tolerances in the national standard is expressed in graphical and language forms and is not adaptable for expression, processing and data transferring with computers. How to interpret its semantics is becoming a focus of relevant studies. This work based on the mathematical definition of form tolerance in ANSI ...
