TL;DR: In this paper, the quantum-mechanical interpretation of vanadyl bond in transition groups was studied and the properties of the initial elements from transition groups were investigated, such as titanium, vanadium, zirconium, niobium, hafnium, tantalum and tungsten.
Abstract: Elements such as titanium, vanadium, zirconium, niobium, hafnium, tantalum, and to some extent molybdenum and tungsten cannot be seen in their common valency states by the electron paramagnetic method; all other valency states of these elements are paramagnetic. A special study should be made of the quantum-mechanical interpretation of vanadyl bond in these minerals; of the crystallochemistry of compounds with a vanadyl bond; of their optical and infrared spectra; and of all compounds of the initial elements from transition groups. — IGR Staff.

TL;DR: A factorized compositional distributional semantics model for the representation of transitive verb constructions that outperforms recent previous work on two established tasks for the transitive Verb construction.
Abstract: We present a factorized compositional distributional semantics model for the representation of transitive verb constructions. Our model first produces (subject, verb) and (verb, object) vector representations based on the similarity of the nouns in the construction to each of the nouns in the vocabulary and the tendency of these nouns to take the subject and object roles of the verb. These vectors are then combined into a final (subject,verb,object) representation through simple vector operations. On two established tasks for the transitive verb construction our model outperforms recent previous work.

TL;DR: The structure of a group which acts symmetrically on a bipartite graph of prime valency is described in terms of simple groups.
Abstract: The structure of a group which acts symmetrically on a bipartite graph of prime valency is described in terms of simple groups. This complements another paper of the author where the graphs other than the bipartite ones were discussed.

TL;DR: In this paper, a very accurate experimental technique is described for the measurement of the Hall coefficients of liquid metals, and the measured Hall coefficient is equal to the free electron value, or the value obtained from an electron concentration equal to an atomic concentration times the valency, 2 for Hg and 3 for In.
