The reinforcement learning (RL) paradigm allows agents to solve tasks through trial-and-error learning. To be capable of efficient, long-term learning, RL agents should be able to apply knowledge gained in the past to new tasks they may encounter in the future. The ability to predict actions' consequences may facilitate such knowledge transfer. We consider here domains where an RL agent has access to two kinds of information: agent-centric information with constant semantics across tasks, and environment-centric information, which is necessary to solve the task, but with semantics that differ between tasks...

Comprehensive data regarding the epidemiology and prevalence of thalassemia in mainland China are lacking. To assess the prevalence of thalassemia, we performed a meta-analysis including 16 articles published from 1981 to 2015. The overall prevalence of α-thalassemia, β-thalassemia and α + β-thalassemia was 7.88%, 2.21% and 0.48%, respectively. Trends in thalassemia prevalence in mainland China were not steady; a prevalence map based on a geographic information system (GIS) showed that the geographic distribution of thalassemia was highest in the south of China and decreased from south to north...

The determination of an appropriate catchment area for a hospital providing highly specialized (i.e. tertiary) health care is typically a trade-off between ensuring adequate client volumes and maintaining reasonable accessibility for all potential clients. This may pose considerable challenges, especially in sparsely inhabited regions. In Finland, tertiary health care is concentrated in five university hospitals, which provide services in their dedicated catchment areas. This study utilizes Geographic Information Systems (GIS), together with grid-based population data and travel-time estimates, to assess the spatial accessibility of these hospitals...
