Surface corona-bar discharges for production of pre-ionizing UV light for pulsed high-pressure plasmas
(2010-12)
Multi-atmospheric pressure, pulsed electric discharge excited lasers require pre-ionization to produce spatially uniform glows. Many such systems use corona bars to produce ultraviolet (UV) and vacuum ultraviolet (VUV) ...
Optical method for inspecting surface defects inside a small bore
(2010-01)
Most automotive powertrain parts made of castings have surface defects such as pores. However, detecting pores inside small diameter bores is a challenge because of the limited dimensional accessibility. Adding to this ...
Towards Designer Microparticles: Simultaneous Control of Anisotropy, Shape, and Size
(WILEY-VCH Verlag, 2010-02-05)
Biodegradable, compositionally anisotropic microparticles with two distinct compartments that exhibit controlled shapes and sizes are fabricated. These multifunctional particles are prepared by electrohydrodynamic co-jetting ...
Disentanglement and decoherence without dissipation at non-zero temperatures
(2010-09)
Decoherence is well understood, in contrast with disentanglement. According to common lore, irreversible coupling to a dissipative environment is the mechanism for loss of entanglement. Here, we show that, on the contrary, ...
Monte Carlo investigations of the effect of beam divergence on thick, segmented crystalline scintillators for radiotherapy imaging
(2010-07)
The use of thick, segmented scintillators in electronic portal imagers offers the potential for significant improvement in x-ray detection efficiency compared to conventional phosphor screens. Such improvement substantially ...
Melanin-Containing Films: Growth from Dopamine Solutions versus Layer-by-Layer Deposition
(WILEY-VCH Verlag, 2010-10-25)
Films formed by oxidation of dopamine are of interest for functionalisation of solid–liquid interfaces owing to their versatility. However, the ability to modulate the properties of such films, for example, permeability ...
Examining gravitational collapse with test scalar fields
(2010-08)
Numerical simulations are performed of a test scalar field in a spacetime undergoing gravitational collapse. The behavior of the scalar field near the singularity is examined and implications for generic singularities are ...
A review of recent developments on turbulent entrainment in stratified flows
(2010-12)
Stratified interfaces are present in many geophysical flow situations, and transport across such an interface is an essential factor for correctly evaluating the physical processes taking place at many spatial and temporal ...
Intracellular electric fields produced by dielectric barrier discharge treatment of skin
(2010-05)
The application of atmospheric pressure plasmas to human tissue has been shown to have therapeutic effects for wound healing and in treatment of skin diseases. These effects are attributed to both production of beneficial ...
Regularized reconstruction in quantitative SPECT using CT side information from hybrid imaging
(2010-05)
A penalized-likelihood (PL) SPECT reconstruction method using a modified regularizer that accounts for anatomical boundary side information was implemented to achieve accurate estimates of both the total target activity ...
