Zro2 Thin-Film-Based Sapphire Fiber Temperature Sensor
(Optical Society of America, 2012-10-01)
A submicrometer-thick zirconium dioxide film was deposited on the tip of a polished C-plane sapphire fiber to fabricate a temperature sensor that can work to an extended temperature range. Zirconium dioxide was selected ...
Signal Processing Of White-Light Interferometric Low-Finesse Fiber-Optic Fabry-Perot Sensors
(Optical Society of America, 2013-08-01)
Signal processing for low-finesse fiber-optic Fabry-Perot sensors based on white-light interferometry is investigated. The problem is demonstrated as analogous to the parameter estimation of a noisy, real, discrete harmonic ...
Preventing Bacterial Colonization Using Colloidal Crystals
(The Royal Society of Chemistry, 2014-07-02)
We investigated the adhesion and colony formation of Pseudomonas aeruginosa PAO1 on a solid coated in close-packed spheres of polystyrene. The objective was to determine the effect of surface topography on the early stages ...
Interplay between static and dynamic polar correlations in relaxor Pb(Mg1/3Nb2/3)O-3
(American Physical Society, 2010-04-01)
We have characterized the dynamics of the polar nanoregions in Pb(Mg1/3Nb2/3)O-3 through high-resolution neutron-backscattering and spin-echo measurements of the diffuse-scattering cross section. We find that the ...
Evidence for anisotropic polar nanoregions in relaxor Pb(Mg1/3Nb2/3)O-3: A neutron study of the elastic constants and anomalous TA phonon damping in PMN
(American Physical Society, 2012-09-18)
We use neutron inelastic scattering to characterize the acoustic phonons in the relaxor Pb(Mg1/3Nb2/3)O-3 (PMN) and demonstrate the presence of a highly anisotropic damping mechanism that is directly related to short-range ...
Instantaneous pressure measurements on a spherical grain under threshold flow conditions
(Cambridge University Press, 2014-02-01)
The aim of this investigation was to experimentally examine the surface pressures and resulting forces on an individual sediment grain whose size is comparable to the scales of the turbulent channel flow in an effort to ...
Replication Pauses of the Wild-Type and Mutant Mitochondrial DNA Polymerase Gamma: A Simulation Study
(Public Library of Science, 2011-11-17)
The activity of polymerase gamma is complicated, involving both correct and incorrect DNA polymerization events, exonuclease activity, and the disassociation of the polymerase: DNA complex. Pausing of pol-gamma might ...
Folate Conjugated Cellulose Nanocrystals Potentiate Irreversible Electroporation-induced Cytotoxicity for the Selective Treatment of Cancer Cells
(Adenine Press, 2014-04-16)
Cellulose nanocrystals are rod-shaped, crystalline nanoparticles that have shown prom- ise in a number of industrial applications for their unique chemical and physical properties. However, investigations of their abilities ...
Development of an individual-based model for polioviruses: implications of the selection of network type and outcome metrics
(Cambridge University Press, 2011-06-01)
We developed an individual-based (IB) model to explore the stochastic attributes of state transitions, the heterogeneity of the individual interactions, and the impact of different network structure choices on the poliovirus ...
The role of large-scale vortical structures in transient convective heat transfer augmentation
(Cambridge University Press, 2013-03-01)
The physical mechanism by which large-scale vortical structures augment convective heat transfer is a fundamental problem of turbulent flows. To investigate this phenomenon, two separate experiments were performed using ...
