Delayed stochastic differential model for quiet standing.

A physiological quiet standing model, described by a delayed differential equation, subject to a white noise perturbation, is proposed to study the postural control system of human beings. It has been found that the white noise destabilizes the equilibrium state, and inertia accelerates the destabilizing process, and that the position of a person is detected and processed by the person's nervous system with a delay. This paper focuses on the analysis of Hopf bifurcation and its stability in this context. Based on the analytical predictions confirmed by numerical simulations, it has been shown that the posture of a person is controlled in such a way that possible amplitude oscillations are minimized.

Type 2 tracheal agenesis without tracheoesophageal fistula.

Tracheal agenesis is a potentially lethal congenital anomaly first described by Payne in 1900. It can occur in isolation or in association with tracheoesophageal (TO) or bronchoesophageal (BO) fistula, cardiovascular anomalies, limb deformities, vertebral anomalies and gastrointestinal tract abnormalities. There are 47 reported cases of tracheal agenesis up to 1989; 45 of these were associated with TO fistula. Another 15 cases of tracheal agenesis have been reported since then, and all have been associated with TO fistula. We report only the third case of type 2 tracheal agenesis without TO fistula.
