In this work, we used the semi-Lagrangian method and the Vlasov code to study the instabilities in a quantum plasma with 1-D temperature anisotropy. Taking the Fermi–Dirac type of distribution function (DF) and using the semi-Lagrangian Vlasov code, we studied the gradual evolution of density and kinetic energy in a degenerate plasma with quantum effects. In this collisionless plasma, adiabatic compression will be along the direction of wave propagation and will lead to temperature anisotropy of the electron distribution that varies along the direction of wave propagation. The findings will find application for dense plasma at finite temperature as in laser-produced plasmas, fusion plasma, as well as solar plasmas. [ABSTRACT FROM AUTHOR]

The effects of developing employees' career abilities (knowing-why, knowing-how, and knowing-whom) on the employing organisation are examined in this study, as well as the function of career happiness in this relationship. The goal of this paper is to contribute to the growing body of knowledge about the effects of employees' boundaryless careers A two-wave quantitative investigation of graduates of a large public university in Hyderabad is used in this study. The findings imply that individuals contribute to company culture, competences, and connections by investing in the development of their career competencies. These contributions, however, are contingent on employees' perceptions of career satisfaction. Employees that are satisfied in their jobs are more likely to give more to their companies. Research limitations/implications - To replicate the current findings, more longitudinal research is needed, supported by a third wave of data collecting. The study emphasises the relevance of career development for employees in the workplace. This is an empirical assessment of the relationship between the development of employees' career competences and their contributions to their employers, as well as one of the first studies to look at career satisfaction as a moderating variable.

We studied the nonlinear evolution of an amplitude-modulated envelop soliton formed in a dense plasma when a laser beam interacts with it. The employment of our newly developed technique, homotopy-assisted symbolic simulation, has been instrumental in the study of the nature and formation of envelope solitons and their dependence on various parameters. The different orders of homotopy perturbation generate a convergent series solution for such nonlinear coupled partial differential equations (PDE). Our technique bypasses the rigorous analytical derivation of coupled PDE without a loss of information. The methodology is very novel and holds promise for application in models that explain experimental observations. The results will be beneficial in interpreting various dense laser plasma interactions. [ABSTRACT FROM AUTHOR]

In this paper, a novel seven-level Quasi-Z-Source-based T -type inverter (7L qZST 2 I) is proposed. The proposed inverter is an upgrade of Quasi-Z-source (qZs) network and seven-level T -type inverter. The 7L qZST 2 I comprises of three qZs-based impedance networks, two bidirectional switches and an H -bridge inverter. It owns the advantages of reduced switch count, improved output voltage gain, enhanced reliability and better quality of output voltage and current. The performance of the proposed topology is tested for two different pulse width modulation techniques based on shoot-through control. The first technique offers simple control and operated at a fixed shoot-through duty cycle for realizing output voltage level. The second technique facilitates independent control of each qZs network dc-link voltage and they can be operated at different shoot through duty cycle which overcomes the limitation of first technique with better quality in output voltage. The detailed operation of the proposed topology and control schemes have been elaborated for different switching states for each output voltage level generation. Extensive simulation and experimentation are performed for both the switching schemes to verify their performance under steady state and dynamic conditions. Furthermore, a brief comparison is constructed to highlight the merits of the proposed inverter with conventional topologies. [ABSTRACT FROM AUTHOR]

Using thermodynamic integration, we calculate free energies of the melt and the crystalline phases of a model system of C[SUB198]H[SUB398] with a realistic all-atom potential. We use the Gibbs-Duhem integration scheme to calculate the melting curve over the experimentally relevant pressure range. The crystal structure and the melting curve obtained from our simulation are in good quantitative agreement with the available experimental results.
