    Abstract: The use of mRNA provides several compelling benefits. Cavitation-mediated delivery of mRNA has yet to be fully explored, especially in the context of achieving delivery of non-encapsulated, “free” mRNA. We present data that explore the relationship between cavitation and the transfer of, and protein expression from, free, fluorescently labelled mRNA. The protein expression exhibited in various cell lines in vitro was further tested in vivo, using sub-micron sized cavitation nuclei and the effects on transfection efficiency and expression time were examined. Acoustic exposure parameters were carefully selected, using a focused 0.5 MHz ultrasound transducer: pressure was varied from 0.3 to 2.1 MPa and 100–50 000 cycles at 5% duty cycle were used to achieve different cavitation regimes. A difference in expression time and transfection rate was observed between different cavitation nuclei and acoustic parameters. A luciferase reporter gene assay was used to characterise events in vitro. Expression due to cavitation-mediated delivery was further examined in vivo using the In Vivo imagining system and quantified using excised homogenised tumour tissue. These results provide us with a measurement window for maximum expression, exploration of how time points change across cell lines and lay the foundations for cavitation-mediated delivery and transfection of free mRNA.

    In: Journal of the International Phonetic Association, Cambridge University Press (CUP)
    Abstract: Garifuna (cab, ISO 639-3) is spoken by the Garifuna people (previously known as Black Caribs and currently also by the plural Garinagu – Cayetano 1993), who reside along the Caribbean coast of Central America in communities in Belize, Honduras, Guatemala and Nicaragua, as well as in a large immigrant population in the United States. Population estimates in the literature for Garifuna speakers worldwide vary widely, but Aikhenvald (1999: 72) estimated between 30 and 100,000 speakers of the language. The latest census in Belize reports a population of 19,639 people who report at least one of their ethnicities as Garifuna and 8,442 people who report speaking Garifuna well enough to hold a conversation (Statistical Institute of Belize 2010 census).

    Abstract: In this study, the researchers investigated the effects of shared and different first language (L1) background, L1 use amounts, and peer familiarity on the frequency of language‐related episodes (LREs) and task scores in interactive pair work. By exploring these variables in distinct interactions, the authors attempted to obtain a more fine‐grained picture of peer interaction patterns and develop strategies to facilitate short interactive tasks. The study’s recordings of the same‐L1 dyads were translated to explore whether the participants stayed on task and why they used their L1. Forty‐two intermediate students of English as a second language (ESL) from various L1 backgrounds recruited from a U.S. university participated in the study. They were placed into four dyad types: same‐L1/familiar, same‐L1/unfamiliar, different‐L1/familiar, and different‐L1/unfamiliar. Each dyad completed a short interactive spot‐the‐difference task. Peer familiarity positively affected the production of LREs and task scores, but no clear differences were found between the same‐L1 and different‐L1 dyads. The researchers also found evidence that peer familiarity affected the same‐L1 and different‐L1 dyads differently. The dyads stayed on task the entire time, using L1 for task management or vocabulary deliberations. Finally, strong negative correlations were found between L1 use amounts and both LREs and task scores.

    Bayesian design of broadband multilayered microperforated panel absorbers
    Acoustical Society of America (ASA) ; 2022

    Abstract: In some noise control and architectural acoustics applications, nonfibrous, hygienic materials are desirable or even strictly required. In meeting such restrictive requirements, microperforated panel (MPP) sound absorbers represent a potential solution. Yet, they typically possess limited absorption bandwidth. Combining multiple MPPs into a multilayer system may broaden the absorption frequency ranges while maintaining high absorption. When increasing the overall absorption bandwidth, each additional MPP layer also increases the complexity of the design process because the design parameters are correspondingly increased by four per each additional layer. This paper applies a Bayesian inferential framework to the design of multilayer MPP absorbers with a parsimonious structural configuration, which penalizes the overlayered configurations. This Bayesian framework demonstrates that the practical design of multilayer MPP absorbers may be accomplished with two levels of model-based inference: model selection and parameter estimation. The design process proceeds inversely from a design target to design parameters, including the required number of MPP layers and their corresponding MPP parameters. This paper discusses the Bayesian design formulation, unified implementation of two levels of Bayesian inference, and experimental validation of a Bayesian design for a multilayered MPP absorber, which is able to meet the design target arising from practice.

    Abstract: It was 1976, hearing conservation and earplug technology had just been advanced by the introduction of the first slow-recovery roll-down foam earplug four years ago, and Elliott Berger had just entered the workforce. Over the next 41 years, Elliott would be a key player in many other advancements in hearing conservation. This paper will briefly summarize his career and contributions to hearing conservation, including research and development of new hearing protectors, standardization of many aspects of hearing conservation, and education of hearing conservation practitioners. Along the way, Elliott documented his work in numerous journal articles, book chapters, and presentations. Several of Elliott's colleagues, collaborators, and friends are here today to fill in more of the details of his career and work to advance hearing conservation.

    The Lombard effect in singing humpback whales: Source levels increase as ambient ocean noise levels increase
    Acoustical Society of America (ASA) ; 2020

    Abstract: Many animals increase the intensity of their vocalizations in increased noise. This response is known as the Lombard effect. While some previous studies about cetaceans report a 1 dB increase in the source level (SL) for every dB increase in the background noise level (NL), more recent data have not supported this compensation ability. The purpose of this study was to calculate the SLs of humpback whale song units recorded off Hawaii and test for a relationship between these SLs and background NLs. Opportunistic recordings during 2012–2017 were used to detect and track 524 humpback whale encounters comprised of 83 974 units on the U.S. Navy's Pacific Missile Range Facility hydrophones. Received levels were added to their estimated transmission losses to calculate SLs. Humpback whale song units had a median SL of 173 dB re 1 μPa at 1 m, and SLs increased by 0.53 dB/1 dB increase in background NLs. These changes occurred in real time on hourly and daily time scales. Increases in ambient noise could reduce male humpback whale communication space in the important breeding area off Hawaii. Since these vocalization changes may be dependent on location or behavioral state, more work is needed at other locations and with other species.

    Lombard effect: Minke whale boing call source levels vary with natural variations in ocean noise
    Acoustical Society of America (ASA) ; 2020

    Abstract: Minke whales were acoustically detected, localized, and tracked on the U.S. Navy's Pacific Missile Range Facility from 2012 to 2017. Animal source levels (SLs) were estimated by adding transmission loss estimates to measured received levels of 42 159 individual minke whale boings. Minke whales off Hawaii exhibited the Lombard effect in that they increased their boing call intensity in increased background noise. Minke whales also decreased the variance of the boing call SL in higher background noise levels. Although the whales partially compensated for increasing background noise, they were unable or unwilling to increase their SLs by the same amount as the background noise. As oceans become louder, this reduction in communication space could negatively impact the health of minke whale populations. The findings in this study also have important implications for acoustic animal density studies, which may use SL to estimate probability of detection.

    Abstract: Research has shown that using acoustic radiation modes combined with surface velocity measurements provide an accurate method of measuring the radiated sound power from vibrating plates. This paper investigates the extension of this method to acoustically radiating cylindrical structures. The mathematical formulations of the radiation resistance matrix and the accompanying acoustic radiation modes of a baffled cylinder are developed. Computational sound power calculations using the vibration-based radiation mode (VBRM) method and the boundary element method are then compared and shown to have good agreement. Experimental surface velocity measurements of a cylinder are taken using a scanning laser Doppler vibrometer and the VBRM method is used to calculate sound power. The results are compared to sound power measurements taken using ISO 3741.
