Analysis of Case-Control Age-at-Onset Data Using a Modified Case-Cohort Method
(WILEY-VCH Verlag, 2008-04)
Case-control designs are widely used in rare disease studies. In a typical case-control study, data are collected from a sample of all available subjects who have experienced a disease (cases) and a sub-sample of subjects ...
A Derivation of the Speed of Light Postulate
(2008-11-28)
The speed of light postulate, one of the two fundamental assumptions upon which the special theory of relativity (SR) is based, still seems as mysterious today as when it was first introduced. This paper presents a derivation ...
Methods and Applications for Detecting Structure in Complex Networks.
(2008)
The use of networks to represent systems of interacting components is now common in many fields including the biological, physical, and social sciences. Network models are widely applicable due to their relatively simple ...
Astronomical Image Subtraction by Cross-Convolution
(2008-04-11)
In recent years, there has been a proliferation of wide-field sky surveys to search for a variety of transient objects. Using relatively short focal lengths, the optics of these systems produce undersampled stellar images ...
Environmentally Responsive Core/Shell Particles via Electrohydrodynamic Co-Jetting of Fully Miscible Polymer Solutions
(WILEY-VCH Verlag, 2008-10)
Herein it is demonstrated that electrohydrodynamic co-jetting is not limited to Janus-type particles, but can also be used for the preparation of core/shell particles. Using side-by-side flow of miscible polymer solutions, ...
Femtosecond pump-probe studies of carrier transport and gain dynamics in quantum cascade lasers
(WILEY-VCH Verlag, 2008-01)
Time-resolved pump-probe differential transmission measurements have been performed on various sets of quantum cascade lasers below and above threshold. Bias-, temperature-, and polarization dependent studies enable a ...
A multi-sensor study of Cl 2 etching of polycrystalline Si
(WILEY-VCH Verlag, 2008-05)
Cl 2 chemistries are the basis for etching of polycrystalline Si and other conductive gate materials in Si CMOS integrated circuit fabrication. It is now well-known that recombination of atomic Cl neutrals on the chamber ...
Coherent control of bound entangled electrons in a CdMnTe quantum well
(WILEY-VCH Verlag, 2008-07)
Ultrafast laser pulses were used to control the spin state of a pair of entangled, donor-bound electrons in a CdMnTe quantum well. The entanglement, mediated by an optically-excited exciton, was characterized by pumpprobe ...
