In the present work, lattice parameters remained the same, that is tetragonal crystal structure for 0% and 100% doping concentration. The electronic band gap of Cu2Zn1−xBaxSn1−ySiyS4 compounds has been gradually increased for continuous increment of doping concentration where the highest electronic band gap is 1.117 eV for Cu2BaSiS4 structure. Moreover, the band gap changes from direct to indirect band gap with the increase of doping concentration in the parent compound. The absorption coefficient has been found to be high (> 104 cm−1) in UV-region for all the doping concentration which makes the studied compound as a potential candidate of absorber layer in the UV detector. The theoretical study of the effect of double doping in the CZTS compound is very interesting for improving the quality of it and it would be a reference for the theoretical and experimental researchers.展开更多

It constitutes a public health problem. Photodynamic therapy (PDT) is one treatment option. This study contributes to the search for photosensitizing molecules used in PDT. Makaluvamines have shown interesting properties in the treatment of several human cancer cell lines. The present study analyzes the ultraviolet and visible absorption spectroscopic properties of a few Makaluvamines. These have been listed in the literature and can be in neutral or charged states (protonated and methylated). The investigation is based on quantum chemical calculations. Molecular geometries and vibrational frequencies have been calculated at the B3LYP/6-311++G(d,p) level. Absorption properties in the visible and ultraviolet spectral range are measured on optimized structures using time-dependent density functional theory (TD-DFT). The absorption spectra are obtained using the “Chemissian” software. The results of our calculations have allowed us to determine the absorption zones of the molecules studied, the energy gaps of the frontier orbitals, the main transitions associated with the absorption process, and their lifetimes. They have also identified four Makaluvamines (E, G, M, and L) that absorb in the therapeutic domain and may have photosensitizer properties.展开更多

In application to the Newton gravitation theory, the analysis consists of three stages. First, we assume that the gravitational force is determined by the initial sphere radius and constant density and does not change in the process of the sphere collapse. The obtained analytical solution allows us to find the collapse time in the first approximation. Second, we construct the step-by-step process in which the gravitational force at a given time moment depends on the current sphere radius and density. The obtained numerical solution specifies the collapse time depending on the number of steps. Third, we find the exact value of the collapse time which is the limit of the step-by-step solutions and study the collapse and the expansion processes in the Newton theory. In application to general relativity, we use the space model corresponding to the special four-dimensional space which is Euclidean with respect to space coordinates and Riemannian with respect to the time coordinate only. The obtained solution specifies two possible scenarios. First, sphere contraction results in the infinitely high density with the finite collapse time, which does not coincide with the conventional result corresponding to the Schwarzschild geometry. Second, sphere expansion with the velocity which increases with a distance from the sphere center and decreases with time.展开更多

With the stress-strain relationship of geometrically exact beam theory, and the principle of virtual displacement and D’Alembert principle, the virtual work balance equation of the tapered cantilever beam element is derived. The internal force, external force, and inertial force virtual work of the beam element is discretized by weak form quadrature element method. The numerical results show the variation of the natural frequency of the beam with the taper when the tapered cantilever beam is not subjected to the load and the free end is subjected to the concentrated load and bending moment.展开更多

Methods: A total of 260 patients with diabetes from a community were selected through convenient sampling and randomly divided into an experimental group and a control group using the random number table method, with 130 cases in each group. Five cases were lost in the experimental group, resulting in 125 effective cases, while all 130 cases in the control group were effective. The control group received standard lectures on diabetes self-management behavior and traditional approaches, such as the distribution of educational manuals. The experimental group underwent a self-management behavior intervention program for diabetic patients based on Snyder’s hope theory model, encompassing three components: goals, pathways, and motivational thinking. The levels of hope and self-management behavior were compared between the two groups. Results: After the intervention, the scores for hope levels and self-management behaviors in both groups were significantly higher than those recorded before the intervention (P < 0.05). Furthermore, the hope level and self-management behavior scores of the experimental group were significantly higher than those of the control group (P < 0.05). Conclusion: The application of Snyder’s hope theory model in diabetic patients demonstrates significant benefits, improving patients’ hope levels and, consequently, enhancing their self-management behaviors.展开更多

It proposes that each material object, including living creatures, is concomitant with a fraction of the charged complex masses of DM and DE in proportion to its mass. This perception provides new insights into the physics of nature and its constituents from subatomic to cosmic scales. This complex nature of DM and DE explains our inability to see DM or harvest DE for the last several decades. The positive complex DM is responsible for preserving the integrity of galaxies and all material systems. The negative complex charged DE induces a positive repelling force with the positively charged DM and contributes to the universe’s expansion. Both fields are Lorentz invariants in all directions and entangle the whole universe. The paper uses CFT to investigate zero-point energy, particle-wave duality, relativistic mass increase, and entanglement phenomenon and unifies Coulomb’s and Newton’s laws. The paper also verifies the existence of tachyons and explains the spooky action of quantum mechanics at a distance. The paper encourages further research into how CFT might resolve several physical mysteries in physics.展开更多
