TL;DR: This paper sketches a valency theory in linguistic terms which includes the discussion of the nature of dependency representation as an interface for semantic description and gives a few examples for how avalency description could be implemented in the EUROTRA-formalism.
Abstract: This paper tries to investigate valency theory as a linguistic tool in machine translation. There are three main areas in which major questions arise:(1) Valency theory itself. I sketch a valency theory in linguistic terms which includes the discussion of the nature of dependency representation as an interface for semantic description.(2) The dependency representation in the translation process. I try to sketch the different roles of dependency representation in analysis and generation.(3) The implementation of valency theory in an MT-system. I give a few examples for how a valency description could be implemented in the EUROTRA-formalism.

TL;DR: In this article, the effect of static impurities inducing diagonal disorder within a one band Hubbard model coupled to a localised state was examined and the formation of local moments near impurity sites and the modification of the transverse spin susceptibility in the antiferromagnetic state.
Abstract: We suggest that when zinc is substituted for copper in the copper oxide planes of high $T_{c}$ superconductors, it does not necessarily have a valency of 2+. Rather, the valency of a zinc impurity should be determined by its surrounding medium. In order to study this hypothesis, we examine the effect of static impurities inducing diagonal disorder within a one band Hubbard model coupled to a localised state. We use this model to discuss the physics of zinc doping in the cuprates. Specifically, we discuss the formation of local moments near impurity sites and the modification of the transverse spin susceptibility in the antiferromagnetic state.

TL;DR: In this article, it was found that all alloys containing odd valency dopants such as Ag (+1), Al (+3) and Sb (+5) have semiconducting behavior and by contrast all alloy containing even valency op-dopes such as Zn (+2) and Sn (+4) have metallic behavior.
Abstract: Five alloys Bi-1at.%Ag, Bi-1at.%Zn, Bi-1at.%Al, Bi-1at.%Sn and Bi-1at.%Sb are produced by rapid solidification using the melt-spinning technique. From x-ray diffraction analysis it was found that these alloys are single phase at room temperature. It is also found that all alloys containing odd valency dopants such as Ag (+1) , Al (+3) and Sb (+5) have semiconducting behavior and by contrast all alloys containing even valency dopants such as Zn (+2) and Sn (+4) have metallic behavior. The produced semiconductors are narrow band semiconductors. The band gap is decreased by increasing valency from 225.1 meV for Bi-Ag system to 12.7 meV for Bi-Sb system.

TL;DR: In this paper, the authors discuss the split between the head and dependent markings of grammatical relations in Yurakare language, and present a method to encode participants on the verb based on transitivity rather than valency.
Abstract: Publisher Summary This chapter discusses the split between the head and dependent markings of grammatical relations in the Yurakare language. Head-marked participants are marked at two different positions in the verbal template of Yurakare: subjects are suffixed and objects are prefixed. In Yurakare, formal encoding of participants on the verb is based on transitivity rather than valency, in the sense that roots are either intransitive or transitive. Additional arguments, whether obligatorily present or not, are formally encoded as applicative objects. Subjects are marked by suffixes that follow the root, derivational information, and tense, mood, and aspect (TMA) markers. The affected object marks a participant that is affected in a nondirect way by the event. Both transitive and intransitive roots can take this applicative marker. With transitive roots, the affected object applicative can be either valency increasing, adding an argument to the existing valence, raising the valence from two to three, or valency rearranging.
