    Notes:
    A 23-year-old female presented with an acute exacerbation of her asthma, for which she required ventilatory support. Her wheeze disappeared immediately following tracheal intubation and ventilatory support was achieved with low airway pressures. We believe that the diagnosis of status asthmaticus was incorrect and that the patient was suffering from vocal cord dysfunction. We review reports of this condition and suggest that, in asthma, the expiratory flow limitation due to paradoxical vocal cord movement may be an appropriate physiological response to improve overall airflow. However, this glottic narrowing may cause respiratory distress of its own accord. Our observations suggest a simple approach to the diagnosis and management of patients whose respiratory distress may be caused by paradoxical vocal cord movement. Immediate relief of ‘bronchospasm’ in an asthmatic following tracheal intubation may establish the correct diagnosis. This has important implications for the management of these patients in the intensive care unit.

    [Auszug] To determine any possible acclimatization of sweat gland production to heat, two 17-month-old bulls were transferred from a warm (Armidale, 30 30' S., 151 35' E., 3,333 ft. altitude) to a hot (Moree, 29 20' S., 150 0' E., 700 ft. altitude) environment. One of the animals was a pure-bred ...

    Notes:
    Abstract The purpose of this paper is to draw a detailed comparison between Newton's method, as applied to discrete-time, unconstrained optimal control problems, and the second-order method known as differential dynamic programming (DDP). The main outcomes of the comparison are: (i) DDP does not coincide with Newton's method, but (ii) the methods are close enough that they have the same convergence rate, namely, quadratic. The comparison also reveals some other facts of theoretical and computational interest. For example, the methods differ only in that Newton's method operates on a linear approximation of the state at a certain point at which DDP operates on the exact value. This would suggest that DDP ought to be more accurate, an anticipation borne out in our computational example. Also, the positive definiteness of the Hessian of the objective function is easy to check within the framework of DDP. This enables one to propose a modification of DDP, so that a descent direction is produced at each iteration, regardless of the Hessian.
