Optimization in the Context of Active Control of Sound
In Computational Science and Its Applications — ICCSA 2003 (Vol. 2668, pp. 801–810).
TL;DR:
A problem of eliminating the unwanted time-harmonic noise on a predetermined region of interest is solved by active means by introducing the additional sources of sound, called controls, that generate the appropriate annihilating signal (anti-sound), and the general solution for controls has been obtained previously.

Alterations in the mechanical properties of the human chondrocyte pericellular matrix with osteoarthritis
JOURNAL OF BIOMECHANICAL ENGINEERING-TRANSACTIONS OF THE ASME, 125(3), 323–333.
MeSH headings : Adult; Aged; Cartilage, Articular / physiopathology; Chondrocytes; Computer Simulation; Elasticity; Extracellular Matrix; Humans; In Vitro Techniques; Micromanipulation / methods; Middle Aged; Models, Biological; Physical Stimulation / methods; Reproducibility of Results; Sensitivity and Specificity; Stress, Mechanical
TL;DR:
Findings suggest that the PCM has an important influence on the stress-strain environment of the chondrocyte that potentially varies with depth from the cartilage surface and the significant loss of PCM stiffness that was observed in osteoarthritic cartilage may affect the magnitude and distribution of biomechanical signals perceived by the chONDrocytes.

2003 journal article
Journal of Scientific Computing, 18(2), 155–189.
author keywords: linear differential operator; discontinuous solution; distribution; monopole; dipole; fundamental solution; convolution; boundary integral; single- and double-layer potentials; surface density of the potential; linear difference operator; multi-layer grid boundary; discontinuous grid function; discrete monopole and dipole layers; Calderon's potential; difference potential
TL;DR:
The motivation for introducing and analyzing the discrete surface potentials was provided by the problems of active shielding and control of sound, in which the source terms that drive the potentials are interpreted as the acoustic control sources that cancel out the unwanted noise on a predetermined region of interest.
