Are Meditative states distinguishable from the pre-meditative ones? A new alternative study

Abstract: Analysis of the HRV signals towards classification of pre-meditative and meditative states has been widely accepted among the research communities. However, none of the existing methods used so far successfully classifies the meditative and pre-meditative states. In this article, we introduce a new approach, which is based on Similarity Index introduced by A.C.C. Yang et. al. The method calculates the rank for each word of length four and compares probability distributions between each pair of subjects (both in meditative and pre-meditative states) by using Q-Q plot. The Q-Q plots show same probability distribution for the meditative states and different probability distributions for the pre-meditative states. Thus Q-Q plots clearly distinguish the meditative states from the pre-meditative ones.

Delay Induced Oscillation in a Biochemical Model and Its Control

Abstract: Time delay is one of the common phenomena often observed in chemical and biological processes which induce instability in biochemical reactions. Since stability of a system is an essential requirement for easy ongoing of any process, an effort has been made in this study to determine the stability criteria for time delayed enzymatic reactions. Enzymes play a vital role in several manufacturing areas including drugs, chemicals, polymers, oils, leather etc. These reactions are usually accompanied by some time delay during formation of the products. This arises mainly due to some conformational changes wherein some time is consumed in changing from one intermediate stage to the other. So, delay induced enzymatic reactions imposes an unstable environment which subsequently affects the product formation but such a situation can be effectively controlled by introducing some control parameters to minimize the delay effect. In this research article, a delay induced mathematical model of enzyme kinetic reaction has been developed and the dynamics of the reaction is significantly analyzed. The effect of time delay on the the system has been analyzed both analytically and numerically. Delay induced oscillations of the system is overcome by applying control on the system. Numerical simulation is carried out to explain the analytical outcomes.

\(Ps^-\) and \(H^+_2\) Ions under Spatial Confinement

Abstract: The ground state energy eigenvalues of the spatially confined symmetric three-body exotic ions \(Ps^-\) and \(H^+_2\) have been determined under the framework of Rayleigh-Ritz variational method. The spatial confinement is simulated by considering an impenetrable spherical box of varying radius around the ion. The electron-electron correlation in \(Ps^-\) and the protonproton correlation in \(H_+^2\) are properly taken care of by expanding the trial wavefunction in explicitly correlated Hylleraas type basis set. The critical radius and the corresponding critical pressure, at which the respective ions destabilize are also reported.
