Superstructural ordering degree in nanosized strontium ferromolybdate according to ferromagnetic resonance data

Ordering Sentences According to Topicality

This paper addresses the problem of finding or producing the best ordering of the sentences in a text. I focus on using semantic properties of the words, as well as the high-level structure of each of the texts, to produce or choose the best ordering. In choosing an original sentence ordering from a group of sentential permutations of the same text, information about the topic of the text is he...

Ferromagnetic ordering in superatomic solids.

In order to realize significant benefits from the assembly of solid-state materials from molecular cluster superatomic building blocks, several criteria must be met. Reproducible syntheses must reliably produce macroscopic amounts of pure material; the cluster-assembled solids must show properties that are more than simply averages of those of the constituent subunits; and rational changes to t...

Linking Data According to Their Degree of Representativeness (DoR)

This contribution addresses the problem of extracting some representative data from complex datasets and connecting them in a directed graph. First we define a degree of representativeness (DoR) inspired of the Borda voting procedure. Secondly we present a method to connect pairwise data using neighborhoods and the DoR as an objective function. We then present case studies as illustrative purpo...

Ferromagnetic Ordering of Energy Levels

We study a natural conjecture regarding ferromagnetic ordering of energy levels in the Heisenberg model which complements the Lieb-Mattis Theorem of 1962 for antiferromagnets: for ferromagnetic Heisenberg models the lowest energies in each subspace of fixed total spin are strictly ordered according to the total spin, with the lowest, i.e., the ground state, belonging to the maximal total spin s...
