Fetal growth restriction at the limits of viability.
The outcome of early small-for-gestational age and/or intrauterine growth-restricted fetuses is reviewed. In these fetuses the outcome appears to be considerably poorer than that of appropriately grown fetuses and this seems mainly to be caused by intrauterine malnutrition rather than by hypoxemia. Active management of intrauterine growth restriction at the limits of viability may not be commen...
متن کاملEthical dilemmas in decision making at limits of neonatal viability
The survival rate for extremely preterm infants has improved over the last two decades. Although the incidence of such births is about 2%, the impact of preterm birth on these infants, their families, health-care providers, and society is profound.

متن کاملLimits in modified categories of interest
We firstly prove the completeness of the category of crossed modules in a modified category of interest. Afterwards, we define pullback crossed modules and pullback cat objects that are both obtained by pullback diagrams with extra structures on certain arrows. These constructions unify many corresponding results for the cases of groups, commutative algebras and can also be adapted to ...
متن کاملTime Limits in Reinforcement Learning
In reinforcement learning, it is common to let an agent interact with its environment for a fixed amount of time before resetting the environment and repeating the process in a series of episodes. The task that the agent has to learn can either be to maximize its performance over (i) that fixed period, or (ii) an indefinite period where time limits are only used during training to diversify exp...
