The c-equivalence principle, commonly accepted as true by most physicists, is the unstated assumption that equals the kinematic speed of light. Should someone prove the principle false, it would render the composition of two Lorentz transformations meaningless. The second hypothesis of the Special Theory of Relativity in its strong form would also be invalidated. This paper examined some of the consequences for physics, should this principle be proven false and outline some experiments to determine light speed, which could falsify the principle and provide evidence for the ether.Full article

A three-level laser with an open cavity and a two-mode vacuum reservoir is explored for its quantum properties. Our investigation begins with a normalized order of the noise operators associated with the vacuum reservoir. The master equation and linear operators' equations of motion are used to determine the equations of evolution of the atomic operators' expectation values. The equation of motion answers are then used to calculate the mean photon number, photon number variance, and quadrature variance for single–mode cavity light and two–mode cavity light. As a result, for γ=0, the quadrature variance of light mode a is greater than the mean photon number for two-mode cavity light. As a result, for the two-mode cavity light, the maximum quadrature squeezing is 43.42 percent.Full article

Recently graph coloring is applied in some real-world applications that involve different types of networks including bipartite graphs. There are two colors are used to color any bipartite graph in which the vertex set is colored with the same integer. This research develops an algorithm for coloring a bipartite graph and the results are tested on sample instances.Full article

The internet originated as a neutral device that was predominantly created to bring ease to the lives of people by making available all the information needed for the growth and prosperity of human beings, but the misuse of this communication medium has created a lot of challenges and the internet addiction is one of them. Internet addiction is a rapidly growing phenomenon exhibiting alarming prevalence rates and a widely recognized problematic condition around the world. Preliminary findings have shown that the unrestrained availability of this communication medium has unfetteredly increased the rate of various complications including psychological disturbances, neurological problems, and social issues. Moreover, it has accelerated the probability of those having an underlying psychological disorder being at serious risk of becoming addicted to the internet, therefore, it has stirred a hot topic of discussion among the mental health communities. The aim of this paper was to deliberately provide a brief overview of the theoretical considerations and ongoing research on internet addiction. A detailed review analysis was performed addressing the types of internet addiction, epidemiology, comorbidities associated with the excessive use of the internet, and different treatment options. Moreover, future areas of research were highlighted stressing the significance of reaching a consensus on characterizing primary features of internet addiction, and an outlook on the future goals of ongoing research has been demonstrated.Full article

Most people can't subscribe to every direct-to-consumer platform today, and the number is growing. The platform's content and the user's experience influence the decision to subscribe or buy. Today's consumers anticipate instantaneously curated content exploration, acquisition, and consumption. Media firms actively seek to increase both click-through rate and profitability by enhancing the user experience and enticing customers to subscribe or buy premium content through recommender systems. The direct-to-consumer platforms may maintain user engagement after consumers have visited the contents by providing suggestions that make the most of the site's rich content catalogs. By bringing it to the attention of viewers based on their viewing habits, for instance, effective recommendation systems might boost earnings for underappreciated "long tail" content. This research explores various recommender system types currently in widespread usage with an analysis of some of the fascinating breakthroughs.Full article
