Intensity Distribution of Waves Transmitted Through a Multiple Scattering Medium [PDF]
The distributions of the angular transmission coefficient and of the total transmission are calculated for multiple scattered waves. The calculation is based on a mapping to the distribution of eigenvalues of the transmission matrix.

Hydroelastic Response to the Effect of Current Loads on Floating Flexible Offshore Platform
An analytical model of a current load’s interaction with a moored floating flexible structure based on the Timoshenko–Mindlin beam theory is developed under the assumption of small-amplitude wave theory and the structural response.

Investigation of nonlinear absorption processes with femtosecond light pulses in lithium niobate crystals [PDF]
The propagation of high-power femtosecond light pulses in lithium niobate crystals (LiNbO3) is investigated experimentally and theoretically in collinear pump-probe transmission experiments.

Thermal mode of a room with integrated regulation of cooling systems
An air-conditioned room with automatic regulation of the climate systems serving it using complex control algorithms is one of the most difficult objects for calculating non-stationary thermal regime, so to date, this method is insufficiently studied. At

Low Momentum Scattering in the Dirac Equation [PDF]
It is shown that the amplitude for reflection of a Dirac particle with arbitrarily low momentum incident on a potential of finite range is -1 and hence the transmission coefficient T=0 in general. If however the potential supports a half-bound state at k=
