Post-traumatic stress disorder (PTSD), panic disorder and phobia manifest in ways that are consistent with an uncontrollable state of fear. Impaired memory for elements of the traumatic experience is a core feature of PTSD, and clinical complaints of memory impairment for non-trauma-related stimuli are common. Several studies have documented generalized memory impairment among patients with com...

In this study, we focus on invariant algebraic curves of generalized Liénard polynomial differential systems x′=y, y′=−fm(x)y−gn(x), where the degrees polynomials f and g are m n, respectively, correct some results previously stated.

We consider the Least Squares (LSQ) regression method for Uncertainty Quantification (UQ) using generalised polynomial chaos (gPC) and augment linear system with gradient of Quantity Interest (QoI) respect to stochastic variables. The is computed very efficiently all variables from adjoint equations. To minimise condition number augmented LSQ system, an effective sampling strategy space require...
