    Abstract: The dependence of the single bubble sonoluminescence (SBSL) on the waveforms of the driving ultrasound has been investigated by both experiment and numerical calculation. Three types of non-simple-harmonic waves, the rectangular, triangular and as well as the sinusoidal wave with a pulse, are used to drive the SBSL in our research. The triangular wave is the most effective, while the rectangular wave is the worst and the sinusoidal wave in the middle. However, the rectangular wave drives the brightest SBSL among those waves if the sound pressure amplitude keeps constant. When we use a simple-harmonic wave with a pulse as the driving sound, stable and periodic SBSL flashes have been observed. An increase in the flash intensity can be observed as the pulse is put at a suitable phase related to the sinusoidal wave. All of the observations are investigated numerically. Well qualitative agreements between the numerical simulations and the experimental measurements have been achieved.

    Nonviral gene transfer to murine liver in vivo is enhanced by exposure to high-amplitude, 1-MHz ultrasound with Optison■.
    Acoustical Society of America (ASA) ; 2006

    Abstract: High-amplitude, 1-MHz ultrasound applied in pulse or burst mode at low duty factor, in conjunction with the injection of a mixture of gas-filled microspheres (Optison■) and plasmid, enhances nonviral gene transfer to surgically exposed murine liver in vivo. In this system, neither plasmid + ultrasound, nor plasmid + Optison produced significant gene expression relative to plasmid-only controls. The combination of plasmid + ultrasound + Optison produced a large enhancement of gene expression. The effect has a strong dependence on acoustic pressure. Together with the dependence of the effect on gas bodies, these results suggest that cavitation-induced permeability changes to hepatocytes are involved. Parametrization studies, the goal of which has been to further enhance gene transfer, will be discussed. At this writing, ultrasound treatments comprised by relatively brief pulses (20–40 cycles) at relatively high pulse repetition frequency (50 Hz) have produced nearly an order of magnitude greater gene expression than produced by tone bursts of several hundred cycles at low pulse repetition frequency (3 Hz) when plasmid and Optison are injected into the portal vein.

    Abstract: Emergent bilinguals (EBs) who are exposed to societal language at school but use another language at home may experience difficulties in mastering the societal language, especially those at risk for language and reading disabilities. Learning phonologically specific new words that discriminate between phonemes may foster phonological awareness and word reading. This study examined the effectiveness of a lexical specificity intervention program that targeted phoneme discrimination in EBs at risk for reading disabilities. EBs who scored below the 25 th percentile on the screening measures were selected and randomly assigned to one of two conditions: at-risk intervention or at-risk control. Of the 76 EBs in the at-risk group, 40 were randomly assigned to receive the intervention. A group of 51 typically developing EBs who did not meet the risk criteria were selected as typical controls. The pre- and post-tests include phoneme discrimination, phonological awareness, rapid automatized naming, fluency, and decoding. The at-risk intervention group showed improvement on the phoneme discrimination task after the intervention and outperformed the at-risk control group but not the typical control group. In addition, growth was observed during both the training and testing sessions of the intervention. The lexical specificity intervention could be a good resource to enhance a key precursor to literacy development for at-risk EBs.

    Transforming acoustic sensing with high refractive index metamaterials

    Abstract: Acoustic sensors play an important role in many areas, such as safety (e.g., sonar arrays), public health (e.g., ultrasonic imaging), surveillance (e.g., underwater communication and navigation), and industry (e.g., non-destructive damage detection). However, conventional acoustic sensors inevitably suffer from the fundamental pressure detection limit, which hinders the performance of current acoustic sensing technologies. Here, we design high refractive index acoustic metamaterials that have strong wave compression effect to obtain direct amplification of pressure fields in metamaterials. This enables a novel metamaterial enhanced acoustic sensing system that can help overcome the detection limit of conventional systems. Through analytical, numerical, and experimental studies, we demonstrate that this novel acoustic sensing system can help achieve over an order of magnitude enhancement in acoustic pressure detection limit. This will allow the detection of weak acoustic signals below the noise floor of the conventional acoustic sensing systems. This work is expected to impact many fronts that require high performance acoustic sensing.

    Mass flow and surface wave in a vertically vibrated granular system
    Acoustical Society of America (ASA) ; 2012

    Abstract: We report an experimental finding on coexistence of the horizontal mass flow and the vertical surface wave in a vertically vibrated granular system. The container is an annular channel with a sawtooth-shaped base which is excited and controlled by a vibration system. The particles are copper spheres with diameter of 3 mm. The driving frequency ƒ and dimensionless acceleration amplitude Γ=4π2ƒ2Α/ɡ (Α is the driving amplitude and ɡ the gravitational acceleration) are used as two control parameters. A high-speed image recording system is used to record the movements of all spheres, and an image processing technique is used to track the locations of all particles. As Γ increases beyond a critical value (about 1.8), the granular layer fluidizes from top to lower parts, and the horizontal mass flow appears. The velocity of the mass flow increases with Γ, and from bottom to top decreases monotonously. In the meanwhile, if Γ exceeds 2.5, the vertical surface wave occurs. The amplitude of the surface wave increases with driving amplitude. The mechanism of the mass flow is the ratchet effect of the sawtooth, while the correlation between the mass flow and the surface wave is to be explored.

    Abstract: A theory of pseudo-Scholte wave propagating in a saturated porous medium loaded on its interface by a viscous compressible liquid is described. The porous medium is simulated by the Biot theory with high-frequency correction, and the overlying liquid is simulated by the linearized Navier-Stokes equation. An analytical expression for the complex dispersion equation of pseudo-Scholte wave through boundary conditions is established. Then the Riemann sheets related to body waves are discussed and the real and imaginary parts of the complex dispersion equation are separated and solved numerically. The resulting phase velocity, attenuation, as well as displacement and pressure fields are analyzed and comparisons are drawn with the non-viscous model. Finally, a set of parametric analyses is carried out to describe the effects of the phase velocity ratios of the S-wave in the porous medium to Ls-mode in overlying liquid on phase velocity and attenuation of the pseudo-Scholte waves.
