The early color sense—Further experiments.

Color sextet scalars in early LHC experiments.

We explore the potential for discovery of an exotic color sextet scalar in same-sign top quark pair production in early running at the LHC. We present the first phenomenological analysis at colliders of color sextet scalars with full top quark spin correlations included. We demonstrate that one can measure the scalar mass, the top quark polarization, and confirm the scalar resonance with 1  fb⁻...

Perturbative Color Transparency in Electroproduction Experiments

We calculate the color transparency ratio for electroproduction of the proton and the pion in perturbative QCD. The calculation includes full integrations over hard interaction kernels and distribution amplitudes in Feynman -x fractions and transverse spatial separation space b. Sudakov effects depending on b and the momentum transferQ are included. Attenuation of the hadronic states propagatin...

Experiments in Sensor Sharpening for Color Constancy

Sensor sharpening has been proposed as a method for improving color constancy algorithms but it has not been tested in the context of real color constancy algorithms. In this paper we test sensor sharpening as a method for improving color constancy algorithms in the case of three different cameras, the human cone sensitivity estimates, and the XYZ response curves. We find that when the sensors ...

Optimal designs for 2-color microarray experiments.

Statisticians can play a crucial role in the design of gene expression studies to ensure the most effective allocation of available resources. This paper considers Pareto optimal designs for gene expression studies involving 2-color microarrays. Pareto optimality enables the recommendation of designs that are particularly efficient for the effects of most interest to biologists. This is relevan...
