Summary: This study analyzed the formation process of hierarchical microstructure in high entropy superalloys (HESAs) by simulating the kinetics of gamma' and gamma precipitations during thermal treatments. The ability of the simulations to reproduce experimentally observed microstructure parameters was evaluated, and temperature time-transformation (TTT) diagrams were calculated to provide guidelines for further optimization of the hierarchical microstructure of HESAs.

Summary: An inverse matrix method is developed to solve resonance masses from a dispersion relation obeyed by a correlation function. The nonperturbative spectral density obtained exhibits resonance structures naturally. The analysis reveals characteristics of different glueballs and proposes a mixing framework including gluonium components for certain mesons.

Summary: The extraction replica technique is a useful method for preparing transmission electron microscopy samples, which eliminates the influence of the surrounding matrix on compositional or crystallographic analysis. This study summarizes the techniques for extracting various precipitates from different alloys and compares the efficiency of the direct replica method with the two-stage replica method. The results indicate that the direct method has a higher particle extraction efficiency for smaller particles and also facilitates the analysis of other features in certain cases.

Summary: The study presents a dispersion-theoretical representation of reaction amplitudes in all charge channels based on modern phase shift input, with a focus on γ K -> K π reactions. It demonstrates the matching of subtraction constants to low-energy theorems and radiative couplings of K(892) resonances, providing a model-independent framework for future high-precision analyses of kaon Primakoff data.

Summary: In this study, a convolutional neural network was used to automate the analysis of TEM images of adipocytes, specifically for the localization and quantification of caveolae. The results show that the model is capable of accurately distinguishing caveolae from noncaveolae regions, making it a valuable tool for characterizing cellular mechanical response.

Summary: We analyze neutral meson mixing by solving the dispersion relation for the mass and width differences of the meson mass eigenstates. We calculate the parameters x and y, which represent the mass and width differences in charm mixing, respectively, using box-diagram contributions as inputs. The SU(3) symmetry breaking is introduced through physical thresholds, stabilizing the solutions. Our predictions for x(m2D) and y(m2D) are close to experimental data. We also predict the coefficient ratio q/p involved in charm mixing, which can be tested by future measurements.

Summary: The article discusses the theoretical feasibility of using energy dispersive x-ray spectroscopy for indirectly measuring the thickness of thin carbon films. By comparing this method with a well-known technique that measures characteristic radiation from the substrate material, the study qualitatively assesses the potential and limitations of using energy dispersive spectroscopy for determining the thickness of thin carbon films through Monte Carlo numerical simulation of characteristic x-ray spectra.

Summary: The study focuses on the fourth order Schrodinger operator H = (-Delta)(2) + V for a short range potential in three space dimensions. A full classification of zero energy resonances is provided, and the dynamic effects on the L-1 -> L-infinity dispersive bounds are studied. It is shown that the natural |t|(-3/4) decay rate can be achieved in all cases, although in some cases a finite rank term needs to be subtracted for certain resonances.

Summary: Two efficient numerical schemes based on L1 formula and Finite-Difference Time-Domain (FDTD) method are constructed for Maxwell's equations in a Cole-Cole dispersive medium. By rigorously carrying out energy stability and error analysis using the energy method, it is proven that both schemes converge with a certain order. Numerical experiments are performed to confirm the theoretical analysis.

Summary: The paper discusses the long wavelength limit of the pressureless two-fluid Euler-Poisson system in three-dimensional whole space. It is proved that the smooth solutions for this system converge strongly to those of the Zakharov-Kuznetsov equation within an O(epsilon(-3/2)) time interval using the Gardner-Morikawa transform and an elaborate energy method.

Summary: In this study, a data-driven analysis of the resonant S-wave ππ→ππ and πK→πK reactions was conducted using partial-wave dispersion relation and Taylor expansion method for accounting the contributions from left-hand cuts. Fits were made to experimental and lattice data, as well as Roy analyses. Analytic continuation to the complex plane revealed poles associated with the lightest scalar resonances for both physical and unphysical pion mass values.
