Starting from the phenomenologically successful color dipole representation of the diffractive structure function, we identify the dominant contribution to the diffractive cross section at small beta. The beta dependence is calculated taking advantage of the Regge factorization properties of the hard mechanism which drives the dependence on the diffractive mass. We impose the unitarity constrai...

This report discusses the cross-section shapes and growth curves created by different proliferation algorithms in an in silico model of in vitro multicellular tumor spheroid growth (MTS). The in vitro MTS system is a model of in vivo tumor growth. The in silico model described herein represents aspects of MTS growth, including its layered structure and growth patterns. An exploration of four al...

 High-aspect-ratio mechanical structures fabricated using deep reactive ion etching generally have a non-rectangular profile. The profile can severely influence the mechanical performance of the device. We have quantified the profile shape for through-wafer etched beams and presented an analytical model to evaluate the effect of profile shape on silicon lateral suspensions. A design methodolog...

One of the useful features of muon colliders is the naturally narrow spread in beam energies. Measurements of threshold cross sections then become a prime candidate for precision measurements of particle masses, widths, and couplings as well as determining particle spin. We describe the potential for measuring cross sections near threshold in supersymmetric theories. INTRODUCTION Muon colliders...

The Baldin sum rule for the nucleon has been recalculated at the light of the most recent photoabsorption cross section measurements. The proton value (α + β) p = 13.69 ± 0.14 is smaller but consistent with the one usually quoted in literature. However, the value for the neutron (α + β) n = 14.40 ± 0.66 turns out to be three standard deviations away from the previously calculated one.

This paper proposes measures of systematic skewness and systematic kurtosis as symmetric measures of risk by extending the work of Kraus and Litzenberg (1976). We examine an asset pricing model that incorporates systematic skewness and systematic kurtosis to test the cross section of asset returns within the context of the Fama and MacBeth (1973) two-pass estimation methodology. However, this e...

This paper presents the visual servoing of a 6 DOF manipulator for unknown 3D profile following. The profile has an unknown curvature, but its cross-section is known. The visual servoing keeps the transformation between a cross-section of the profile and the camera constant with respect to 6 degrees of freedom. The position of the profile with respect to only five degrees of freedom can be meas...
