We study the corrections to the determination of sin(2β) from the time dependent CP asymmetry of B → J/ΨKS which arise in the standard model. Although a precise prediction of these corrections is not possible we find that they are indeed extremely small, of the order of less than a per mil of the observed value. This means in turn that any deviation visible at the B factories will be a clear si...

Subspace identification techniques are reinterpreted via classical realization theory to formulate a wide class of subspace identification methods. Re-formulating subspace identification in terms of a low rank decomposition of a weighted Hankel matrix allows special cases such as impulse-based and step-based input signals, but also realization based on arbitrary input signals and correlation fu...

Several intersection graphs such as curves-in-the-plane graphs, circular-arc graphs, chordal graphs and interval graphs are reviewed, especially on their recognition algorithms. In this connection graph realization problem is mentioned.

There is growing agreement that the potential benefits of implementing business technologies will not be realised through the relatively simple act of going live with a new software application. Indeed, there is clear evidence that organisations must explicitly plan for, and proactively manage, the realisation of benefits, if a new technology is to deliver real value to its host organisation. I...

Purpose – The purpose of this paper is to give some theoretical suggestions and practical approaches in support of the implementation of “cluster supply chain” (CSC), which is a new management paradigm and enhances the competitiveness of small and medium enterprises (SMEs) through integrating the advantages of supply chain and industrial cluster. Design/methodology/approach – A case study of cl...

We describe a graph-based generation system that participated in the TUNA attribute selection and realisation task of the REG 2008 Challenge. Using a stochastic cost function (with certain properties for free), and trying attributes from cheapest to more expensive, the system achieves overall .76 DICE and .54 MASI scores for attribute selection on the development set. For realisation, it turns ...

The authors have recently proposed a model for a neural mechanism of internal timer. Here we report on predictions, which the model provides for psychological experiment of interval timing by the method of reproduction. We consider the ratio " /m with m and being the mean and the kth central moment of the lengths of intervals reproduced by a subject. The model predicts that for arbitrary k, is ...

One approach to deliberation about the choice of what to do in a particular situation is to use an argument scheme based on the practical syllogism to supply a presumptive reason for the action, which is then subjected to a process of critical questioning to see if the presumption can be maintained. In this paper we describe an implemented realisation of this approach. We describe a representat...

We discuss the origin of the difference between the harmonic value of the width of the multiphonon giant resonances and the smaller observed value. Analytical expressions are derived for both the effective width and the average cross-section. The contribution of the Brink-Axel mechanism in resolving the discrepancy is pointed out. . ∗Supported in part by CNPq and FAPESP.

The graph realization problem is to find for given nonnegative integers a1, . . . , an a simple graph (no loops or multiple edges) such that each vertex vi has degree ai. Given pairs of nonnegative integers (a1, b1), . . . , (an, bn), (i) the bipartite realization problem ask whether there is a bipartite graph (no loops or multiple edges) such that vectors (a1, ..., an) and (b1, ..., bn) corres...
