I discuss QCD sum rules determinations of the form factors governing the decay B ! ( )` . For some of these form factors the computed dependence on the momentum transferred does not agree with the expectation from the nearest pole dominance hypothesis. Relations are observed among the form factors, that seem to be compatible with equations recently derived by B.Stech. The measurement of a numbe...

The last decade has witnessed a number of signi®cant methodological advances and developments in the assessment of psychopathy. The Psychopathy ChecklistÐRevised and the two-factor model of psychopathy have facilitated the assessment of psychopathy and clari®ed the di€erential correlates of the personalityand behavior-based operationalizations of this syndrome. Although preliminary evidence sug...

PURPOSE The SDM-Q-9 and SDM-Q-Doc measure patient and physician perception of the extent of shared decision making (SDM) during a physician-patient consultation. So far, no self-report instrument for SDM was available in Dutch, and validation of the scales in other languages has been limited. The aim of this study was to translate both scales into Dutch and assess their psychometric characteris...

Kalman filtering is very efficient for data fusion, in which the definition of the process and measurement noises (i.e. the matrices Q and R, respectively) greatly influences the filter performance. In recent years several studies reported that adjustments of Q and R can be helpful to reduce the errors of the estimations. In this paper, various methods for making adjustments to the matrices Q a...

The key issues of Information Technology (IT) managers of Brazilian banking, a highly advanced industry, were assessed. The resulting priorities are comparable to those found in developed countries. As well as the usual key issues method of rating, two other methods were used: Q-sort and interpretive structured modeling (ISM). Respondents Q-sorted issues, and a factor analysis on these data ide...

The fundamental sensitivity limit of atomic force microscopy is strongly correlated to the thermal noise cantilever oscillation. A method suppress this unwanted reduce bandwidth measurement, but approach limited by speed measurement and width resonance, commonly defined through quality factor Q. However, it has been shown that optomechanical resonances in interferometers might affect oscillatio...

We report a precision measurement of the parity-violating asymmetry $A_{PV}$ in elastic scattering longitudinally polarized electrons from $^{208}$Pb. measure $A_{PV}=550\pm 16 {\rm (stat)}\pm 8\ (syst)}$ parts per billion, leading to an extraction neutral weak form factor $F_W(Q^2 = 0.00616\ GeV}^2) 0.368 \pm 0.013$. Combined with our previous measurement, extracted neutron skin thickness is $...

Semileptonic D meson decays are of great physics interest because their description is relatively simple. The decay matrix for semileptonic D meson decay decouples into a weak current component (describing the Wlνl vertex), and a strong current term (for the Wcq̄ vertex) that is parameterized through form factor functions of the invariant mass (q) of the W exchanged. The form factors can not be ...
