Aab Ky Marr! Pulwama to Balakot: India's New Normal

Pulwama/Balakot crisis is important for several reasons. The prime amongst it is that Pakistan changed the rule of the game. It not only thwarted India's design, it effectively demonstrated that it could respond to any Indian aggression through conventional means. The paper argues that although India and Pakistan had a narrow escape during the conflict, there is a need for a cautious approach when it comes to Indo-Pakistan strategic stability. The papers focus on the crisis behavior of both countries and argue that while India intentionally initiated the crisis whereas Pakistan took every step to deescalate. At the end of the crisis, Modi claimed that India was prepared to hit Pakistan with multiple missiles if it had not returned the IAF pilot. While it might be music to his ultra-Hindu fundamentalist supporters, in fact, it was nothing but a desperate attempt to restore his credibility. In the subcontinental culture, aab ky Marr explains such a mindset.

Monte Carlo tracking drift-diffusion trajectories algorithm for solving narrow escape problems

This study deals with a narrow escape problem, a well-know difficult problem of evaluating the probability for a diffusing particle to reach a small part of a boundary far away from the starting position of the particle. A direct simulation of the diffusion trajectories would take an enormous computer simulation time. Instead, we use a different approach which drastically improves the efficiency of the diffusion trajectory tracking algorithm by introducing an artificial drift velocity directed to the target position. The method can be efficiently applied to solve narrow escape problems for domains of long extension in one direction which is the case in many practical problems in biology and chemistry. The algorithm is meshless both in space and time, and is well applied to solve high-dimensional problems in complicated domains. We present in this paper a detailed numerical analysis of the method for the case of a rectangular parallelepiped. Both stationary and transient diffusion problems are handled.
