Structural properties in ruptured mitral chordae tendineae measured by synchrotron-based X-ray phase computed tomography

Journal of Synchrotron Radiation, 2023
The link between the structural properties and the rupturing of chordae tendineae in the mitral valve complex is still unclear. Synchrotron-radiation-based X-ray phase computed tomography (SR-XPCT) imaging is an innovative way to quantitatively analyze ...

Heating of gas inside radio sources to mildly relativistic temperatures via induced Compton scattering [PDF]

, 2001
Measured values of the brightness temperature of low-frequency synchrotron radiation emitted by powerful extragalactic sources reach 10^11--10^12 K. If some amount of nonrelativistic ionized gas is present within such sources, it should be heated as a ...

Scattering of gravitational radiation: second order moments of the wave amplitude [PDF]

, 2004
Gravitational radiation that propagates through an inhomogeneous mass distribution is subject to random gravitational lensing, or scattering, causing variations in the wave amplitude and temporal smearing of the signal.

Multiple light scattering and optomechanical forces [PDF]

, 2010
When off-resonant light travels through a transparent medium, light scattering is the primary optical process to occur. Multiple-particle events are relatively rare in optically dilute systems: scattering generally takes place at individual atomic or ...

A numerical approach for acoustic radiation and scattering of moving bubbles at low frequencies

Frontiers in Physics, 2023
The acoustic radiation and scattering of underwater bubbles play an important role in ocean exploration, target localization, acoustic measurements, etc. The two-phase fluid flow and moving boundary result in the lack of means to predict the sound field,

Radiative contribution to classical gravitational scattering at the third order in G [PDF]

, 2020
Working within the post-Minkowskian approach to General Relativity, we prove that the radiation-reaction to the emission of gravitational waves during the large-impact-parameter scattering of two (classical) point masses modifies the conservative ...
