2D or 3D? How cell motility measurements are conserved across dimensions in vitro and translate in vivo
(2019-11-19)Cell motility is a critical aspect of several processes, such as wound healing and immunity; however, it is dysregulated in cancer. Current limitations of imaging tools make it difficult to study cell migration in vivo. ... -
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 ... -
Acceleration Feedback-Based Active and Semi-Active Seismic Response Control of Rail-Counterweight Systems of Elevators
(Hindawi, 2005-01-01)Based on the observations in the past earthquake events, the traction elevators in buildings are known to be vulnerable to earthquake induced ground motions. Among several components of an elevator, the counterweight being ... -
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 ... -
The adhesion function of the sodium channel beta subunit (beta 1) contributes to cardiac action potential propagation
(2018-08-14)Computational modeling indicates that cardiac conduction may involve ephaptic coupling - intercellular communication involving electrochemical signaling across narrow extracellular clefts between cardiomyocytes. We ... -
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 ... -
Allele-specific methylation in the FADS genomic region in DNA from human saliva, CD4+ cells, and total leukocytes
(2018-04-06)Abstract Background Genetic variants within the fatty acid desaturase (FADS) gene cluster (human Chr11) are important regulators of long-chain (LC) polyunsaturated fatty acid ... -
Anti-Swing Control of Gantry and Tower Cranes Using Fuzzy and Time-Delayed Feedback with Friction Compensation
(Hindawi, 2005-01-01)We designed a feedback controller to automate crane operations by controlling the load position and its swing. First, a PD tracking controller is designed to follow a prescribed trajectory. Then, another controller is added ... -
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 ... -
Astrocyte Mechano-Activation by High-Rate Overpressure Involves Alterations in Structural and Junctional Proteins
(Frontiers, 2019-02-22)Primary blast neurotrauma represents a unique injury paradigm characterized by high-rate overpressure effects on brain tissue. One major hallmark of blast neurotrauma is glial reactivity, notably prolonged astrocyte ... -
