Generalized isocline method of plotting phase-plane trajectories [PDF]
By considering simultaneously the N-x (or the N-\dot{x} ), where N=d\dot{x}/dx and the \dot{x}-x planes, second order non-linear autonomous systems (not easily amendable to the existing methods) described by the differential equation \ddot{x}=F(x, \dot{x}) can be studied.

Selkov’s Dynamic System of Fractional Variable Order with Non-Constant Coefficients
This article uses an approach based on the triad model–algorithm–program. The model is a nonlinear dynamic Selkov system with non-constant coefficients and fractional derivatives of the Gerasimov–Caputo type.

Phase-Type Distributions of Animal Trajectories with Random Walks
Animal monitoring systems often rely on expensive and challenging GPS-based systems to obtain accurate trajectories. However, an alternative approach is to generate synthetic trajectories that exhibit similar statistical properties to real trajectories ...

ABSTRACT Purpose Patient activation—encompassing knowledge, confidence, and skills in managing individual's health—is a cornerstone of person‐centered care. However, its significance among childhood, adolescent, and young adult cancer survivors (CAYACS) remains unexplored. This article examines the application of the 13‐item Patient Activation Measure (

ON BEHAVIOR OF TRAJECTORIES OF WEAK SOLUTIONS OF N-DIMENSIONAL STOCHASTIC NAVIER-STOKES EQUATIONS
The research paper study a behavior of trajectories of weak solutions of n-dimensional (n≥2) Navier-Stokes equations, perturbed by an additive white noise. It is shown that at any given moment t trajectories in its subsequent motion along the phase space

Abstract Background Sickle cell disease (SCD) is an autosomal recessive hemoglobinopathy affecting millions of individuals worldwide. The clinical expression and psychosocial burden of SCD vary widely across geographical, cultural, and healthcare system contexts, underscoring the need for setting‐specific approaches to assessment.
