Spin-orbit and orbit-orbit strengths for radioactive neutron-rich doubly magic nucleus 132^{132}Sn in relativistic mean field theory

Relativistic mean field (RMF) theory is applied to investigate the properties of the radioactive neutron-rich doubly magic nucleus $^{132}$Sn and the corresponding isotopes and isotones. The two-neutron and two-proton separation energies are well reproduced by the RMF theory. In particular, the RMF results agree with the experimental single-particle spectrum in $^{132}$Sn as well as the Nilsson spin-orbit parameter $C$ and orbit-orbit parameter $D$ thus extracted, but remarkably differ from the traditional Nilsson parameters. Furthermore, the present results provide a guideline for the isospin dependence of the Nilsson parameters.Comment: 4 pages, 4 figures, Phys. Rev. C in pres

Tripartite evolutionary game analysis of power battery carbon footprint disclosure under the EU battery regulation

The EU's battery regulation aims to promote low-carbon and sustainable batteries and achieve carbon neutrality goals. However, in the actual implementation, limited government supervision, asymmetric information, and economic interests may induce battery manufacturers and third-party verification agencies to manipulate carbon footprint data. To prevent the occurrence of the above phenomena, this study constructs a tripartite evolutionary game model involving battery manufacturers, third-party verification agencies, and national market authorities. The model examines the strategic decision-making process, influential factors, and evolutionary stability of the three players, followed by simulation analysis. The results showed that the evolutionary system may exhibit two stable states: (0,0,1) and (1,1,0), corresponding to two strategy combinations {disclose false carbon footprints, intend rent-seeking, supervise} and {disclose true carbon footprint, reject rent-seeking, not supervise}, respectively. However, if the benefits of third-party agencies objectively assessing carbon footprints are not substantial enough, there will be only one stable state (0,0,1) in the system. To guide the evolutionary system towards the desired stable state (1,1,0), supportive policies should be implemented along with the EU battery regulation. Therefore, this study puts forward some policy recommendations in terms of institutional improvement, database construction, and the application of emerging technologies

Selective gas detection using Mn3O4/WO3 composites as a sensing layer

Pure WO3 sensors and Mn3O4/WO3 composite sensors with different Mn concentrations (1 atom %, 3 atom % and 5 atom %) were successfully prepared through a facile hydrothermal method. As gas sensing materials, their sensing performance at different temperatures was systematically investigated for gas detection. The devices displayed different sensing responses toward different gases at specific temperatures. The gas sensing performance of Mn3O4/WO3 composites (especially at 3 atom % Mn) were far improved compared to sensors based on pure WO3, where the improvement is related to the heterojunction formed between the two metal oxides. The sensor based on the Mn3O4/WO3 composite with 3 atom % Mn showed a high selective response to hydrogen sulfide (H2S), ammonia (NH3) and carbon monoxide (CO) at working temperatures of 90 degrees C, 150 degrees C and 210 degrees C, respectively. The demonstrated superior selectivity opens the door for potential applications in gas recognition and detection

Business sustainability for competitive advantage: identifying the role of green intellectual capital, environmental management accounting and energy efficiency

Themanufacturing organizations are threatening the earth and its wildlife because of their growing concern about environmental pollution and industrial waste. Hence, in the present study, the three potential solutions, Green Intellectual Capital, Environmental Management Accounting and Energy Efficiency, are evaluated for excelling the organizational operations towards business sustainability and attaining the Competitive Advantage. With the assistance of ‘Partial Least Square-Structural Equation Modelling’ on the dataset of 364 respondents from the manufacturing organizations in China, the outcome reported the positive and significant impact of all of the studied potential solutions in excelling and enhancing business sustainability and competitive advantage. Based on the findings, it is proposed that manufacturing organizations need to apportion due attention to developing the green intellectual capital, improve the level of consumption of energy and need to disclose their environmentalmanagement through proper Environmental Management Accounting

Tetrahedral shape of 110^{110}Zr from covariant density functional theory in 3D lattice space

Covariant density functional theory is solved in 3D lattice space by implementing the preconditioned conjugate gradient method with a filtering function (PCG-F). It considerably improves the computational efficiency compared to the previous inverse Hamiltonian method (IHM). This new method is then applied to explore the tetrahedral shape of $^{110}$Zr in the full deformation space. The ground state of $^{110}$Zr is found to have a tetrahedral shape, but the deformations $\beta_{31}$ and $\beta_{33}$ greatly soften the potential energy surface. This effect is analysed with the microscopic evolution of the single-particle levels near the Fermi surface driven by the deformation

Decelerating Airy pulse propagation in highly non-instantaneous cubic media

The propagation of decelerating Airy pulses in non-instantaneous cubic medium is investigated both theoretically and numerically. In a Debye model, at variance with the case of accelerating Airy and Gaussian pulses, a decelerating Airy pulse evolves into a single soliton for weak and general non- instantaneous response. Airy pulses can hence be used to control soliton generation by temporal shaping. The effect is critically dependent on the response time, and could be used as a way to measure the Debye type response function. For highly non- instantaneous response, we theoretically find a decelerating Airy pulse is still transformed into Airy wave packet with deceleration. The theoretical predictions are confirmed by numerical simulations
