Absorption of Broadband Low-Frequency Sound Beyond the Thermodynamics Limit: An Acoustic Resonator With Magnetic Bearing. [PDF]

Adv Sci (Weinh)
This work presents a magnetic‐bearing acoustic resonator that overcomes the thermodynamics limit of sound absorption. By introducing tunable negative stiffness, it achieves broadband low‐frequency absorption within a compact cavity, far exceeding the performance achievable by classic mass‐tuned designs.

Ground movements during diaphragm wall installation in clays [PDF]

, 1993
PhDDiaphragm walls are being used increasingly in connection with building basements and road improvement schemes, particularly in urban areas. Many of these walls retain overconsolidated clay, and the magnitude of the lateral stresses which will act ...

Early changes in rat diaphragm biology with mechanical ventilation [PDF]

, 2003
To better characterize the effects of 24-hour mechanical ventilation on diaphragm, the expression of myogenic transcription factors, myosin heavy chains, and sarcoplasmic/endoplasmic reticulum calcium-ATPase pumps was examined in rats.

Benchmarking of finite-difference time-domain method and fast multipole boundary element method for room acoustics

, 2022
Compared to geometrical acoustics, wave-based methods which solve the wave equation either in the time domain or in the frequency domain are known for their high accuracy.

Binaural Auralization of Room Acoustics with a Highly Scalable Wave-Based Acoustics Simulation

, 2023
This paper presents a proposal of an efficient binaural room-acoustics auralization method, an essential goal of room-acoustics modeling. The method uses a massively parallel wave-based room-acoustics solver based on a dispersion-optimized explicit time ...

Patterns and predictors of adherence to diaphragm use in a phase III trial in sub-Saharan Africa: a trajectory analysis.

, 2009
BACKGROUND: We examined diaphragm adherence among 2429 women randomized to the intervention arm (diaphragm + gel + condoms) in Methods for Improving Reproductive Health in Africa, a phase III trial of the diaphragm for HIV prevention in Zimbabwe and ...

Literary Acoustics [PDF]

, 2015
Bringing together sound studies and intermediality theory, this essay revisits the notion of ‘literary acoustics’ to inquire into the usefulness of intermediality studies for analyzing the relations between literature and sound.
