Biochemical sensors based on polymer microrings with sharp asymmetrical resonance
(The American Institute of Physics, 2003-08-25)
Photonic microresonators have great potential in the application of highly sensitive sensors due to high Q-factor resonances and steep slopes between zero and unity transmission. A microring resonator with increased resonance ...
Nanoscale thermal transport
(The American Institute of Physics, 2003-01-15)
Rapid progress in the synthesis and processing of materials with structure on nanometer length scales has created a demand for greater scientific understanding of thermal transport in nanoscale devices, individual ...
Magnetically modulated optical nanoprobes
(The American Institute of Physics, 2003-02-17)
We have developed magnetically modulated optical nanoprobes (MagMOONs) to magnetically modulate the signal from fluorescent probes and thus separate it from autofluorescence, electronic offsets, and other background signals. ...
Cosmic string in the van Stockum cylinder
(IOP Publishing Ltd, 2003-05-07)
The low density van Stockum dust solution is extended by including an angular deficit factor. The resulting model describes a rotating Gott–Hiscock string surrounded by an annular dust atmosphere. The interior spacetime ...
A soluble string theory of hadrons
(IOP Publishing Ltd, 2003-05-01)
We consider Penrose limits of the Klebanov-Strassler and Maldacena-Núñez holographic duals to N = 1 supersymmetric Yang-Mills. By focusing in on the IR region we obtain exactly solvable string theory models. These ...
Profiling and modeling of dc nitrogen microplasmas
(The American Institute of Physics, 2003-09-01)
This article explores electric current and field distributions in dc microplasmas, which have distinctive characteristics that are not evident at larger dimensions. These microplasmas, which are powered by coplanar thin-film ...
The microwave spectrum, ab initio analysis, and structure of the fluorobenzene–hydrogen chloride complex
(The American Institute of Physics, 2003-05-22)
The fluorobenzene–hydrogen chloride π-hydrogen-bonded complex has been studied by high resolution microwave spectroscopy and ab initio calculations. Rotational spectra of the C6H5F–H35Cl,C6H5F–H35Cl, C6H5F–H37Cl,C6H5F–H37Cl, ...
Ion characteristics of laser-produced plasma using a pair of collinear femtosecond laser pulses
(The American Institute of Physics, 2003-07-21)
Femtosecond laser-pulse absorption is studied in silicon ablation plasmas by means of a pair of identical 1016 W/cm21016W/cm2 collinear pulses separated on a picosecond time scale. The second laser-pulse modifies ionic ...
Surfactant spreading on thin viscous films: film thickness evolution and periodic wall stretch
(Springer-Verlag, 2003-01)
Surfactant spreading on thin viscous films is of interest in the context of surfactant and liquid transport in the lungs, for both normal lung function and treatment of disease, as well as for many industrial processes. ...
DSMC Simulation of the Cometary Coma
(The American Institute of Physics, 2003-05-05)
The study of the comet coma, or its tenuous atmosphere, is a major space application of rarefied gas dynamics, which requires modeling the gas flow in a wide range of Knudsen number. For weak to moderate comets, only the ...
