Summary: Monte Carlo simulation was used to calculate the electron backscattering coefficients of molybdenum and tungsten at different energies. The simulated data showed good agreement with experimental data at higher energies, but discrepancies at lower energies may be related to surface contamination with carbonaceous atomic layers.

Summary: In this paper, a theory is proposed to explain the difference in acoustic scattering at different directions of a bubble cluster when it is driven by ultrasound. The theory predicts the angular distribution of scattered acoustic pressure under different parameters and is proven to be correct under circumstances of small clusters and weak interactions. This theory not only sheds light on the physics of bubble cluster scattering, but also may contribute to the improvement of ultrasound imaging technology, including ultrasonic harmonic imaging and contrast-enhanced ultrasonography.

Summary: The Real Extended Bialas-Bzdak (ReBB) model is used to describe the proton-proton elastic differential cross section data published by the TOTEM Collaboration at LHC. The model predicts a significant Odderon signal in the kinematic range of 0.37 <= -t <= 1.2 GeV2 at root s = 8 TeV. However, when considering the Odderon signals from earlier TOTEM data at different energies, the combined significance is dominated by the 7 TeV data.

Summary: This study presents a distance insensitive measurement system for acquiring the reflectance from turbid media. The system's geometric relationships are discussed theoretically and verified through Monte Carlo simulations. An experimental setup is also provided to validate the theoretical considerations. The measurement system allows for accurate reflectance measurements with minimal deviation, as compared to traditional fiber-based detection units.

Summary: In this theoretical study, the elastic Rayleigh scattering of x-ray photons by closed-shell atoms is investigated, focusing on the transfer of linear polarization from incident to outgoing photons. By using the density-matrix formalism combined with relativistic perturbation theory, general relations between the Stokes parameters of incident and scattered photons are derived. It is shown that analyzing the polarization purity of synchrotron radiation using Rayleigh scattering can be done without the need for theoretically calculated scattering amplitudes, by measuring linear polarization of scattered light at azimuthal angles of 0 degrees and 45 degrees.

Summary: A model has been developed to predict the effect of random seafloor roughness on synthetic aperture sonar image statistics. By quantifying the changes in image statistics, the model can link image statistics to measurable geo-acoustic properties. Additionally, this research demonstrates the potential use of synthetic aperture sonar systems for remote sensing of roughness parameters.

Summary: The study introduces an improved active fiber-based retroreflector for high-quality wavefront-retracing anti-parallel laser beams in the near UV, with applications in precision spectroscopy of atomic hydrogen. Weak aberrations produced by the fiber collimator can be characterized through caustic measurement and limit the performance of the AFR, with implications for systems requiring collimated high-quality laser beams. Additionally, advancements in collimator design, alignment, and control have been made to stabilize the intensity of the wavefront-retracing beams and monitor polarization.

Summary: The influence of particle size on underwater active polarization imaging is investigated using Monte Carlo simulation and quantitative experiments. The results show a non-monotonic relationship between the particle size of scatterers and imaging contrast. The polarization evolution of backscattered light and target diffuse light is quantitatively analyzed, revealing significant changes in the polarization and intensity scattering field with particle size.

Summary: This study investigates the scattering of high-energy photons from radioactive contaminants in solid-state target materials and their impact on the low-energy background for sub-GeV dark matter direct-detection searches. The results show that this background is most noticeable for energy deposits in the 1-100 meV range and requires active measures to suppress it.

Summary: The study aims to propose an approximate method for decomposing discretized BUX into components of each channel. By using the probability separation (P separation) method and testing it with Be-11 scattering, the research demonstrates that the approximate way can reproduce exact BUXs well regardless of specific configurations or resonance positions.

Summary: Monitoring tumor response to treatment in real time using spatial frequency domain imaging (SFDI) shows promise as a noninvasive and label-free method to quantify changes in tissue optical scattering. This optical technique may serve as an early predictive biomarker of treatment response, outperforming traditional parameters such as tumor volume or functional parameters like oxygen saturation.
