AIM Physicians' inappropriate prescribing habits affect patients' lives both medically and financially. To avoid these unwanted situations, the World Health Organization defined the rational use of drugs (RUD) in 1985. This study aimed to investigate whether patients were as informed about their diagnosis and medication as anticipated and their knowledge about the RUD in general. METHODS A qu...

Deep Deterministic Policy Gradient (DDPG) algorithm is one of the most well-known reinforcement learning methods. However, this method inefficient and unstable in practical applications. On other hand, bias variance Q estimation target function are sometimes difficult to control. This paper proposes a Regularly Updated (RUD) policy gradient for these problems. theoretically proves that procedur...

A combination of solid-phase-extraction (SPE) and reversed-phase preparative high-performance liquid chromatography (prep-HPLC) of the methanolic extract of the aerial parts of Artemisia splendens (common name: “Asia Minor Wormwood”), an endemic Iranian species, afforded Zand E-melilotosides (1 and 2), Zand E-4-methoxy-melilotosides (3 and 4), and a new dimer, bis-ortho-Z-melilotoside (5, named...

and call a set A provident if it is transitive and closed under all p-rud-rec functions with p a member of A. * If ζ is the least ordinal not in a provident set A, then ζ is indecomposable, that is, that the sum of two ordinals less than ζ is less than ζ. Conversely, if ζ is indecomposable, η > ζ and p ∈ Jζ , then the Jensen set Jη is is closed under all p-rud rec functions; in particular Jζ is...
