Moving beyond the classic difference-in-differences model: A simulation study comparing statistical methods for estimating effectiveness of state-level policies
Beth Ann Griffin, Megan S. Schuler, Elizabeth A. Stuart +7
State-level policy evaluations commonly employ a difference-in-differences (DID) study design; yet within this framework, statistical model specification varies notably across stud…
Scalable Metagrating for Efficient Ultrasonic Focusing
Yan Kei Chiang, Li Quan, Yugui Peng +4
Acoustic focusing plays a pivotal role in a wide variety of applications ranging from medical science to nondestructive testing. Previous works have shown that acoustic metagrating…
Institutional Research Computing Capabilities in Australia: 2024
Slava Kitaeff, Luc Betbeder-Matibet, Jake Carroll +11
Institutional research computing infrastructure plays a vital role in Australia's research ecosystem, complementing and extending national facilities. This paper analyses research…
Metahouse: noise-insulating chamber based on periodic structures
Mariia Krasikova, Sergey Krasikov, Anton Melnikov +4
Noise pollution remains a challenging problem requiring the development of novel systems for noise insulation. Extensive work in the field of acoustic metamaterials has led to occu…
Acoustic meta-atom with maximum Willis coupling
Anton Melnikov, Li Quan, Sebastian Oberst +3
Acoustic metamaterials are structures with exotic acoustic properties, having promising applications in acoustic beam steering, focusing, impedance matching, absorption and isolati…
A Multimodal Vision Foundation Model for Clinical Dermatology
Siyuan Yan, Zhen Yu, Clare Primiero +22
Diagnosing and treating skin diseases require advanced visual skills across domains and the ability to synthesize information from multiple imaging modalities. While current deep l…
Structural tunability in metamaterials
Mikhail Lapine, David Powell, Maxim Gorkunov +3
We propose a novel approach for efficient tuning of the transmission characteristics of metamaterials through a continuous adjustment of the lattice structure, and confirm it exper…
Analytical design of acoustic metasurface cells incorporating meander-line and Helmholtz resonators
Dingcheng Yang, Yan Kei Chiang, David Powell
Gradient acoustic metasurfaces have shown strong potential for manipulation of acoustic waves across the audible and ultrasonic frequency ranges. The key challenge in designing aco…
Acoustic radiation force and radiation torque beyond particles: Effects of non-spherical shape and Willis coupling
Shahrokh Sepehrirahnama, Sebastian Oberst, Yan Kei Chiang +1
Acoustophoresis deals with the manipulation of sub-wavelength scatterers in an incident acoustic field. The geometric details of manipulated particles are often neglected by replac…
