amide-iminol tautomerism was studied for ionized oxamic acid (oa+•) in the gas phase using thedft method with the ub3lyp functional and various basis sets {6-31++g(d,p), 6-311+g(d,p), and augcc-pvdz}. among twenty tautomers-rotamers possible for oa+•, eleven isomers were found to bethermodynamically stable. similarly as for the neutral molecule, ionization (oa → oa+• + e) favors theamidization ...

this paper investigates the nature of absolutive case and the syntactic mechanisms underlying its licensing. to this end, two recent minimalist approaches to the syntactic derivation of ergative structure will be introduced. drawing on evidence from the syntactic derivation of clauses with intransitive complex predicates in kurdish, it will be established that the absolutive case is checked by ...

We examine the informal exchange of favors among the members of a society. We characterize the network patterns of interaction that sustain repeated favor exchange. Networks sustainable in renegotiation-proof equilibria have certain inductive critical structures. The networks also satisfying a robustness condition, so that removing a link only results in the loss of favors in a local neighborho...

Automated negotiation research focuses on getting the most value from a single negotiation, yet real-world settings often involve repeated serial negotiations between the same parties. Repeated negotiations are interesting because they allow the discovery of mutually beneficial solutions that don’t exist within the confines of a single negotiation. This paper introduces the notion of Pareto eff...
