Current theories view learning as the acquisition of specific predictions1–4. Humans and animals learn to predict the outcomes of their behavior, including rewards. Learning depends on the extent to which these outcomes are different than predicted, being governed by the discrepancy or ‘error’ between outcome and prediction. Outcomes that affect learning in this way are termed ‘reinforcers’. Le...

متن کاملAnticancer Phenolics from Dryopteris fragrans (L.) Schott.
Cancer is one of the most major diseases that threatens human health and life. The aim of this work was to obtain novel anticancer molecules from D. fragrans, a kind of medicinal plant. The structure of the new compound was identified using spectroscopic data (¹H-NMR, 13C-NMR and two dimensions NMR). Its anticancer properties were evaluated using the 3-(4,5-dimethyl-2-thiazolyl)-2,5-diphenyl-2-...
متن کاملThe Modified Schultz Index of Trees
For a graph G = (V,E), the modified Schultz index of G is defined as S∗(G) = ∑ {u,v}⊂V (G) (dG(u) · dG(v))dG(u, v) where dG(u) (or d(u)) is the degree of the vertex u of G, and dG(u, v) is the distance between u and v. Lower bounds on modified Schultz index in trees in terms of the order and diameter are determined. Mathematics Subject Classification: 05C05, 05C12
متن کاملExtremal Modified Schultz Index of Bicyclic Graphs
For a graph G = (V,E), the modified Schultz index of G is defined as S∗(G) = ∑ {u,v}⊆V (G) (dG(u) · dG(v))dG(u, v) where dG(u) (or d(u)) is the degree of the vertex u of G, and dG(u, v) is the distance between u and v. Let B(n) be the set of bicyclic graph with n vertices. In this paper, we study the modified Schultz index of B(n), graphs in B(n) with the smallest modified Schultz index S∗(G) a...
