Rayleigh-Taylor mixing: confinement by stratification and geometry [PDF]
, 2010 Rayleigh-Taylor instability has been an area of active research in fluid dynamics for the last twenty years, but relatively little attention has been paid to the dynamics of problems where Rayleigh-Taylor instability plays a role, but is only one ...

Frequency-Mixing Lasing Mode at European XFEL
Applied Sciences, 2021 We demonstrate generation of X-ray Free-Electron Laser (XFEL) pulses in frequency mixing mode at the SASE3 line of the European XFEL. The majority of the SASE3 FEL segments are tuned at two frequencies ω1 and ω2 following an alternate pattern. Leveraging

Mixed mode matrix multiplication [PDF]
Proceedings. IEEE International Conference on Cluster Computing, 2003 In modern clustering environments where the memory hierarchy has many layers (distributed memory, shared memory layer, cache, ...), an important question is how to fully utilize all available resources and identify the most dominant layer in certain computation.

Polarization resolved four-wave-mixing-based measurement in bulk material semiconductor optical amplifier [PDF]
, 2006 The anticipated growth in demand for bandwidth leads to the development of all-optical signal processing techniques at ever increasing data rates. One possible candidate to achieve the required performance is the semiconductor optical amplifier (SOA). It

Transverse-mode coupling effects in scanning cavity microscopy
New Journal of Physics, 2019 Tunable open-access Fabry–Pérot microcavities enable the combination of cavity enhancement with high resolution imaging. To assess the limits of this technique originating from background variations, we perform high-finesse scanning cavity microscopy of ...

Orbital Angular Momentum (OAM) Mode Mixing in a Bent Step Index Fiber in Perturbation Theory
IEEE Photonics Journal, 2019 Within the framework of perturbation theory, we explore in detail the mixing of orbital angular momentum (OAM) modes due to a fiber bend in a step-index multimode fiber.

Analysis of Vehicle Platform Vibration Based on Empirical Mode Decomposition
Shock and Vibration, 2021 Vehicle platform vibration (VPV) directly affects the measurement accuracy of precise measuring instrument (PMI) fixed on it. In order to reduce the influences of VPV on measurement accuracy, it is necessary to perform vibration isolation between vehicle

The influence of initial conditions on turbulent mixing due to Richtmyer-Meshkov instability [PDF]
, 2010 This paper investigates the influence of different three-dimensional multi-mode initial conditions on the rate of growth of a mixing layer initiated via a Richtmyer-Meshkov instability through a series of well-controlled numerical experiments. Results
