Joint model-based recognition and localization of overlapped acoustic events using a set of distributed small microphone arrays [PDF]

open access: yes, 2017
In the analysis of acoustic scenes, often the occurring sounds have to be detected in time, recognized, and localized in space. Usually, each of these tasks is done separately.

From Clinic to Computation: Multiscale Bioengineering Strategies for Durable Biological Aortic Valve Replacements

open access: yesAdvanced Functional Materials, EarlyView.
Bioprosthetic aortic valves have revolutionized the treatment of aortic stenosis, but their durability is limited by structural valve deterioration (SVD). This review focuses on the pericardial tissue at the heart of these valves, examining how its mechanical properties and calcification drive fatigue and failure.

The Acoustical Performance of Rooms [PDF]

open access: yesThe Journal of the Acoustical Society of America, 1948
It is appreciated that the reverberation characteristic is only one measure representing the acoustical performance of a room. Measurements have been made on a number of average size studios and rooms using techniques other than reverberation measurement. Equipment has been constructed to produce an audio signal varying continuously in frequency and in

Revealing the Hidden Role of Cd in p‐Type Mg3Sb2: Enhanced Thermoelectric Performance by Grain Boundary Segregation Engineering

open access: yesAdvanced Functional Materials, EarlyView.
The hidden role of Cd segregation at grain boundaries is revealed in p‐type Mg3Sb2 by atom probe tomography and other advanced characterizations. Grain boundary Cd enrichment suppresses the SbMg+ hole‐killer formation and lowers potential barriers, enhancing electrical conductivity.
