Natural phenomena are dominated by the occurrence of oscillations and waves, whether it is light propagation, water wave disturbance, magneto hydrodynamics or plasma oscillations. There are many common features encompassing wave propagation and oscillatory behaviours in these diverse systems.Full Text

On 11 August 2018, the country lost one of the most promising and dynamic upcoming researchers. Kuppuswamy Porsezian, Professor of Physics, Pondicherry Central University, breathed his last at Apollo Hospitals, Chennai due to an unexpected and sudden liver condition at the rather young age of 55. He was destined to achieve greater heights in science but nature snatched him quite unexpectedly leaving his loving family, colleagues, students and a large circle of friends in India and abroad in great despair.Full Text

We consider the pandemic spreading of COVID-19 in India after the outbreak of the coronavirus in Wuhan city, China. We estimate the transmission rate of the initial infecting individuals of COVID-19 in India using officially reported data at the early stage of the epidemic with the help of the susceptible (S), exposed (E), infected (I), and removed (R) population model, the so-called SEIR dynamical model. Numerical analysis and model verification are performed to calibrate the system parameters with official public information about the number of people infected, and then to evaluate several COVID-19 scenarios potentially applicable to India. Our findings provide an estimation of the number of infected individuals in the pandemic period of timeline, and also demonstrate the importance of governmental and individual efforts to control the effects and time of the pandemic-related critical situations. We also give special emphasis to individual reactions in the containment process.Keywords
