Ablation outcome of irreversible electroporation on potato monitored by impedance spectrum under multi-electrode system
(2018-09-20)Background Irreversible electroporation (IRE) therapy relies on pulsed electric fields to non-thermally ablate cancerous tissue. Methods for evaluating IRE ablation in situ are critical to assessing treatment ... -
Acoustic Receptivity of a Boundary-Layer to Tollmien-Schlichting Waves Resulting From a Finite-Height Hump At Finite Reynolds-Numbers
(AIP Publishing, 1994-11-01)The acoustic receptivity of a boundary layer to Tollmien-Schlichting (T-S) waves resulting from a finite-height hump at finite Reynolds numbers is investigated. The steady flow is calculated using an interacting boundary-layer ... -
Acoustic streaming in a waveguide with slowly varying height
(Acoustical Society of America, 1984-01-01)An analysis of acoustic streaming in a two-dimensional waveguide having slowly varying height is presented. Special attention is paid to waveguides with cross sections that are small compared to the acoustic and/or wall ... -
Acoustic wave propagation in a circular cosh duct carrying a mean flow
(Acoustical Society of America, 1987-09-01)An analysis of acoustic wave propagation in a waveguide carrying an incompressible mean flow is presented. The radius of the waveguide is taken to vary slowly as a function of axial location. It is shown that the dynamic ... -
Acoustic waves in ducts with sinusoidally perturbed walls and mean flow
(Acoustical Society of America, 1975)An analysis is presented of the propagation of acoustic waves in a hard-walled duct with sinusoidally perturbed walls and carrying mean flow. The results show that resonance occurs whenever the wavenumber of the wall ... -
Activation of bacterial channel MscL in mechanically stimulated droplet interface bilayers
(Springer Nature, 2015-09-08)MscL, a stretch-activated channel, saves bacteria experiencing hypo-osmotic shocks from lysis. Its high conductance and controllable activation makes it a strong candidate to serve as a transducer in stimuli-responsive ... -
Adiabatic Following in Two-Photon Transition
(American Physical Society, 1977-03-01)The coherent interaction of two smoothly varying, near-resonant, two-photon pulses with a three-level system can be described by "two-photon damped Bloch equations" which are analogous to those for a one-photon transition ... -
Age-related strength loss affects non-stepping balance recovery
(Public Library of Science, 2019-01-18)Aging is associated with a higher risk of falls, and an impaired ability to recover balance after a postural perturbation is an important contributing factor. In turn, this impaired recovery ability likely stems from ... -
Algebraically growing waves in ducts with sheared mean flow
(Acoustical Society of America, 1974)Standing or traveling waves which vary algebraically with the axial distance in uniform ducts with sheared mean velocity profiles are investigated. The results show that such waves are not possible for ducts with uniform ... -
Application of sub-micrometer vibrations to mitigate bacterial adhesion.
(2014-03-11)As a prominent concern regarding implantable devices, eliminating the threat of opportunistic bacterial infection represents a significant benefit to both patient health and device function. Current treatment options focus ... -
Arrival times for dissipative, nonlinear second-sound waves in solids
(American Physical Society, 1995-07-01)We extend our original analysis begun in Tarkenton et al. [Phys. Rev. B 49, 11 794 (1994)] to include dissipative effects that are important in real cryogenic systems where nonlinear second sound exists. We present results ... -
Assessment of Deep Partial Thickness Burn Treatment with Keratin Biomaterial Hydrogels in a Swine Model
(Hindawi Publishing Corp, 2016-01-01)Partial thickness burns can advance to full thickness after initial injury due to inadequate tissue perfusion and increased production of inflammatory cytokines, which has been referred to as burn wound progression. In ... -
Asymptotic Solutions Of Second-Order Linear Equations with 3 Transition Points
(AIP Publishing, 1974-12-01)A uniformly valid asymptotic expansion is obtained for the regular solution of a class of second_order linear differential equations with three transition points_a turning point and two regular singular points. The solution ... -

Bending vibration of cantilevered thin-walled beams subjected to time-dependent external excitations
(Acoustical Society of America, 1995-07-01)The bending vibration of cantilevered thin-walled beams of arbitrary closed cross section exposed to time-dependent external excitations is investigated. The beam model used in this study incorporates a number of nonclassical ... -
Biomechanics of hair cell kinocilia: experimental measurement of kinocilium shaft stiffness and base rotational stiffness with Euler-Bernoulli and Timoshenko beam analysis
(Company of Biologists Ltd., 2011-03-01)Vestibular hair cell bundles in the inner ear contain a single kinocilium composed of a 9+2 microtubule structure. Kinocilia play a crucial role in transmitting movement of the overlying mass, otoconial membrane or cupula ... -
Breakdown of structural models for vibrations of single-wall zigzag carbon nanotubes
(American Institute of Physics, 2009-09-15)Free vibrations of zigzag single-wall carbon nanotubes (SWCNTs) of aspect ratio (length/diameter) similar to 6 and with ends traction-free have been studied using molecular mechanics (MM) simulations with the MM3 potential. ... -
Buckling of Dielectric Elastomeric Plates for Soft, Electrically Active Microfluidic Pumps
(The Royal Society of Chemistry, 2014-05-15)Elastic instabilities, when properly implemented within soft, mechanical structures, can generate advanced functionality. In this work, we use the voltage-induced buckling of thin, flexible plates to pump fluids within a ...
