Understanding and measuring mechanical signals in the tumor stroma

FEBS Open Bio, EarlyView.
This review discusses cancer‐associated fibroblast subtypes and their functions, particularly in relation to extracellular matrix production, as well as the development of 3D models to study tumor stroma mechanics in vitro. Several quantitative techniques to measure tissue mechanical properties are also described, to emphasize the diagnostic and ...

Study on Doppler characteristics of underwater bistatic reverberation [PDF]

MATEC Web of Conferences, 2019
Active sonar has two typical types of geometry configuration respectively named monostatic and bistatic like a radar system. In the monostatic scenario, co-located underwater transducers transmit and receive sound energy, while in a bistatic situation ...

Spatial Reverberation and Dereverberation using an Acoustic Multiple-Input Multiple-Output System [PDF]

J. Audio Eng. Soc, vol. 65, no. 1/2, pp. 42-55, 2017
Methods are proposed for modifying the reverberation characteristics of sound fields in rooms by employing a loudspeaker with adjustable directivity, realized with a compact spherical loudspeaker array (SLA). These methods are based on minimization and maximization of clarity and direct-to-reverberant sound ratio.

Estimation of the Area of a Reverberant Plate Using Average Reverberation Properties

Physics Procedia, 2015
This paper aims to present an original method for the estimation of the area of thin plates of arbitrary geometrical shapes. This method relies on the acquisition and ensemble processing of reverberated elastic signals on few sensors. The acoustical Green's function in a reverberant solid medium is modeled by a nonstationary random process based on the

Study of reverberation pattern and its cancellation method in shallow water [PDF]

Theoretical and Applied Mechanics, 2007
In shallow water, the primary limitation of the performance of active sonar is the reverberation that originates from volume and boundaries scattering as well as multi-path propagation. There­fore, reverberation cancelation is an important research topic

Towards modelling X-ray reverberation in AGN: Piecing together the extended corona [PDF]

, 2016
Models of X-ray reverberation from extended coronae are developed from general relativistic ray tracing simulations. Reverberation lags between correlated variability in the directly observed continuum emission and that reflected from the accretion disc arise due to the additional light travel time between the corona and reflecting disc.

The Lick AGN Monitoring Project 2011: Reverberation Mapping of Markarian 50 [PDF]

, 2011
The Lick AGN Monitoring Project 2011 observing campaign was carried out over the course of 11 weeks in Spring 2011. Here we present the first results from this program, a measurement of the broad-line reverberation lag in the Seyfert 1 galaxy Mrk 50 ...

Speech Dereverberation with A Reverberation Time Shortening Target [PDF]

arXiv, 2022
This work proposes a new learning target based on reverberation time shortening (RTS) for speech dereverberation. The learning target for dereverberation is usually set as the direct-path speech or optionally with some early reflections. This type of target suddenly truncates the reverberation, and thus it may not be suitable for network training.

The Acoustics of the Double Elliptical Vault of the Royal Palace of Caserta (Italy)

Buildings, 2017
This work investigates the acoustic characteristics of the double elliptical vault, which overlooks the Grand Staircase of the Royal Palace of Caserta (Italy). The Royal Palace was built by the architect Luigi Vanvitelli in the Seventeenth Century and it

Effects of noise and reverberation on speech perception and listening comprehension of children and adults in a classroom-like setting

Noise and Health, 2010
The effects of classroom noise and background speech on speech perception, measured by word-to-picture matching, and listening comprehension, measured by execution of oral instructions, were assessed in first- and third-grade children and adults in a ...
