Summary: This paper addresses the issue of large amplitude dust acoustic solitons in a charge varying dusty plasma with ions following a Cairns-Gurevich distribution. By introducing the correct Cairns-Gurevich ion charging current and analyzing the impact of variable dust charge, it is found that the spatial patterns of the variable charge solitary wave are significantly changed. The addition of trapped nonthermal ions in the plasma makes the solitary structure less spiky, increases the net negative charge on dust grain surface, and contributes to electron depletion.

Summary: The interaction between positron acoustic soliton waves (PASWs) and arbitrary collision angle in plasma, which includes cold fluid positrons, stationary ions, and electrons with Kappa-Cairns (K-C) distribution function, is studied. The equations of Korteweg-de Vries (KdV) and the phase shifts are obtained using the extended Poincare'-Lighthill-Kuo (PLK) method. The influences of parameters of the K-C distribution function (kappa and alpha), collision angle theta, and the proportion of the ion (electron) and positron unperturbed densities (beta i(beta e)) on the phase shifts are investigated.

Summary: According to the study, wealth is distributed more unequally than labor earnings, influenced by luck, attitudes towards saving decisions, and growth rates of labor earnings. Strong motives for people to save and firms to demand capital raise the equilibrium interest rate, causing wealth to grow faster than labor earnings and resulting in a more uneven distribution of wealth compared to labor earnings.

Summary: Dust explosions can occur when the dust exceeds its minimum explosible concentration in the presence of confinement, oxidizer, dispersing agent, and an ignition source. A study was conducted to investigate the dust properties that affect suspension in confined spaces. Dust samples from five grain types were obtained and tested for various characteristics. The results showed significant differences among the grain dust types, and the study contributed to the understanding of grain dust properties and their release into the atmosphere. Quantifying these properties is important for creating better grain handling procedures for improved health and safety.

Summary: The study explores the relationship between dust emission-flux PSD and wind friction velocity in vegetated, supply-limited aeolian systems, finding that the fine fraction of dust particles increases with friction velocity. Results suggest that models assuming wind-invariance of the emission-flux PSD may not be applicable for crusted soils with vegetation, highlighting the need for more accurate dust models across different types of drylands for land management, air quality improvement, and climate applications.

Summary: The study focuses on the dust grain surface potential in multi-ion plasmas with two negative ions within the context of kappadistributed dusty plasma. Results show that the dust grain surface potential strongly depends on parameters like kappa, density, and temperature ratios. The behavior of dust grain surface potential exhibits non-monotonic trends and is minimally affected by temperature ratios. Considering a variety of Xe+-F- -SF6- and Ar+-F- -SF6- masses is important for the analysis of plasma physics, especially in multicomponent plasmas.

Summary: This paper explores the use of physics-informed neural networks (PINNs) for predicting the transcranial ultrasound wave propagation. By embedding the wave equation, time snapshots data, and boundary conditions in the loss function during training, PINNs can flexibly apply to different wave equations and boundary conditions. By adding physics constraints to the loss function, PINNs can predict wavefields far outside the training data, providing ideas for improving the generalization capability of existing deep learning methods.

Summary: This study fabricated Kesterite Cu2ZnSnS4 (CZTS) thin films with various concentrations of 1,8-diiodooctane (DIO) polymer additive by electrochemical deposition. The optical, electrical, morphological, and structural properties of the CZTS thin films synthesized with concentrations of 5 mg/mL, 10 mg/mL, 15 mg/mL, and 20 mg/mL were investigated. The analysis showed the formation of the pure kesterite crystal structure and the presence of pure CZTS. Scanning electron microscopy confirmed well-grown films with uniform deposition and a grain size of approximately 4 μm. The photovoltaic properties of the CZTS thin films were also studied, and the best-performing device achieved a conversion efficiency of 4.82%.

Summary: In this study, Gd-doped In2O3 thin films with a wide range of Gd doping concentration were chemically produced and their properties were investigated. The films exhibited a cubic structure and were nearly stoichiometric. The optical properties showed a shift in energy gap towards lower wavelengths with increasing Gd doping. Hall effect studies revealed changes in carrier concentration and hall mobility. The construction of a heterojunction device and investigations into its dark characteristics were carried out. The undoped In2O3 films displayed significant magnetism, while the Gd-doped films showed faint ferromagnetism, which was attributed to the formation of oxygen vacancies during the film production process.
