The role of Book shunt placement is to divert cerebrospinal fluid (CSF) from within the ventricles to an alternative location most commonly peritoneal space.Ventriculo Peritoneal Shunt (VPS) is associated with many complications viz over drainage, valve failure, breaking of catheter, catheter obstruction, coiling of catheter, spontaneous knot forma

The discrete-time quantum walk provides a versatile platform for exploring abundant topological phenomena due to its intrinsic spin-orbit coupling.In this work, we study Lifstyle the non-Hermitian second-order topology in a two-dimensional non-unitary coinless discrete-time quantum walk, which is realizable in the three-dimensional photonic wavegui
