An investigation of the sound of foam and its potential influence on the shampoo experience

International Journal of Cosmetic Science, Volume 48, Issue 4, Page 725-737, August 2026.
This study investigates shampoo foam acoustics' impact on hair washing experience using binaural recordings and psychoacoustic analysis. Distinct foam sound profiles elicited varying emotional responses; early lathering induced negative emotions while later phases were positive.

Contrasting Palaeogeographic Histories but Similar Microevolutionary Responses in Low‐Dispersal Island Grasshoppers From Two Mediterranean Archipelagos

Journal of Biogeography, Volume 53, Issue 8, August 2026.
ABSTRACT Aim Island archipelagos serve as natural laboratories for understanding how geological history, climate change and dispersal limitation interact to shape diversification. Here, we examine how these forces influence patterns of genomic divergence, demographic dynamics and phenotypic variation in island‐endemic taxa, with a particular focus on ...

Cybersecurity in aquaculture: Risks, governance, and future directions across production systems

Journal of the World Aquaculture Society, Volume 57, Issue 4, August 2026.
Abstract Aquaculture is becoming increasingly dependent on connected sensors, remote monitoring, edge and cloud analytics, automation, and digital traceability; however, the cybersecurity evidence base remains fragmented and low‐trophic systems are markedly underrepresented.

Ground‐Truthed Fiber‐Optic Sensing Reveals Internal Tide Bores Over Madeira's Steep Slope

Geophysical Research Letters, Volume 53, Issue 13, 16 July 2026.
Abstract We demonstrate the combined utility of distributed acoustic sensing (DAS) and repeat conductivity‐temperature‐depth (CTD) profiling for observing internal tide dynamics over a sloping seafloor. While DAS has been widely proposed as a method to infer ocean temperature variability from seafloor cables, quantitative in situ validation has been ...

Spectral Mapping Using Kernel Principal Components Regression for Voice Conversion

Archives of Acoustics, 2013
The Gaussian mixture model (GMM) method is popular and efficient for voice conversion (VC), but it is often subject to overfitting. In this paper, the principal component regression (PCR) method is adopted for the spectral mapping between source speech ...

Bidirectional equalization for underwater acoustic communication

Journal of the Acoustical Society of America, 2012
The bidirectional decision feedback equalizer (BiDFE) that combines the outputs of a conventional decision feedback equalizer (DFE) and backward DFE can improve the performance of the conventional DFE by up to 1–2 dB based on simulations. In this letter, the BiDFE concept is extended to multichannel time reversal communications involving a DFE as a ...

Multipath correlations in underwater acoustic communication channels

Journal of the Acoustical Society of America, 2013
Uncorrelated scattering (US), which assumes that multipath arrivals undergo uncorrelated scattering and are thus uncorrelated, has been the standard model for digital communications including underwater acoustic communications. This paper examines the cross-correlation of multipath arrivals based on at-sea data with different temporal coherence time ...

Synchronization techniques for underwater acoustic communications

International Journal of Communication Systems, 2023
SummaryUnderwater acoustic channel is a challenging medium for communication due to the presence of significant multipath, high noise, frequency‐dependent propagation loss, and high and non‐uniform Doppler spread. Doppler shift is non‐negligible in underwater communication due to the low velocity of underwater signals.
