FONDUE: A Framework for Node Disambiguation and Deduplication Using Network Embeddings

Data often have a relational nature that is most easily expressed in a network form, with its main components consisting of nodes that represent real objects and links that signify the relations between these objects. Modeling networks is useful for many purposes, but the efficacy of downstream tasks is often hampered by data quality issues related to their construction. In many constructed networks, ambiguity may arise when a node corresponds to multiple concepts. Similarly, a single entity can be mistakenly represented by several different nodes. In this paper, we formalize both the node disambiguation (NDA) and node deduplication (NDD) tasks to resolve these data quality issues. We then introduce FONDUE, a framework for utilizing network embedding methods for data-driven disambiguation and deduplication of nodes. Given an undirected and unweighted network, FONDUE-NDA identifies nodes that appear to correspond to multiple entities for subsequent splitting and suggests how to split them (node disambiguation), whereas FONDUE-NDD identifies nodes that appear to correspond to same entity for merging (node deduplication), using only the network topology. From controlled experiments on benchmark networks, we find that FONDUE-NDA is substantially and consistently more accurate with lower computational cost in identifying ambiguous nodes, and that FONDUE-NDD is a competitive alternative for node deduplication, when compared to state-of-the-art alternatives.

Mythological Conceptualization in A.O. Balabanov’s Films and Interpretation of “The River”

This paper attempts to uncover the semantic message of “The River”, an unreleased film that was supposed to be a new program product in the filmwork of Aleksei Oktyabrinovich Balabanov. At the beginning of the article, the author reveals the director’s method of conceptualizing his films that appeal to the mythological conceptualization of the narrative structure in addition to the plot and genre of the film. The latter is clarified in the process of comparing the films with the structure of a fairy tale, which has also already been noted by some researchers of Balabanov’s movies. The novelty of the article is connected with a philosophical analysis of the indicated conceptualization of “The River” film-project (2002) and an attempt to identify aesthetic effects and symbolic meanings encoded in the film production.The author believes that the close attention of “The River” project’s director to the cultures of traditional society, and especially the culture of northerners — the Tofalars (Tofa), the Yakuts (Sakha), is due to the proximity of the traditional cultures of the North and the Arctic to the mythological method of conception in culture. In this sense, “The River” project was, in all likelihood, to become the director’s experiment in building an archaic topos with a crystalline mythological concept of the abundance of the natural over the cultural and the corresponding mentality and psychology of the actions of the “old era”. The main thing in this cinematic experiment was to take the culture “off the table” and analyze the natural spontaneity in human nature, with the subsequent “splitting” of mythological consciousness, breaking the epic circle of tradition with a symbolic outcome, through the concept of “boat” and “river”, to a universal human principle, metaphysical topos of thought. The prophetic gift of the director, embodied in a number of his films, is interpreted on the example of “The River” and reflects the message for the path of self-development of the cultures of Russian peoples.

The Formation and Early Evolution of the Greensburg, Kansas, Tornadic Supercell on 4 May 2007

During the evening of 4 May 2007, a large, powerful tornado devastated Greensburg, Kansas. The synoptic and mesoscale environments of the parent supercell that spawned this and other tornadoes are described from operational data. The formation and early evolution of this long-track supercell, within the context of its larger-scale environment, are documented on the basis of Weather Surveillance Radar-1988 Doppler (WSR-88D) data and mobile Doppler radar data. The storm produced tornadoes cyclically for about 30 min before producing a large, long-lived tornado. It is shown that in order to have forecasted the severe weather locations and times accurately, it would have been necessary to have predicted 1) the localized formation of an isolated convective storm near/east of a dryline, 2) the subsequent splitting and resplitting of the storm several times, 3) the growth of a new storm along the right-rear flank of an existing storm, and 4) the transition from the cyclic production of small tornadoes to the production of one, large, long-track tornado. It is therefore suggested that both extreme sensitivity to initial conditions associated with storm formation and the uncertainty of storm behavior made it unusually difficult to forecast this event accurately.

Morphology and structure of filiform papillae of neonates: a light and scanning electron microscopic study

The present study was carried out to describe the morphology and structure of filiform papillae of the neonate. Ten tissue specimens taken from the anterior portion of the tongue of ten stillborn neonates were fixed and processed for both light and scanning electron microscopy. Filiform papillae appeared as small finger-like projections with rounded tips and appeared to develop as two or three papillae originating from one base;subsequent splitting of the papillae from each other then took place. The epithelium covering the papillae was parakeratinized while that covering the interpapillary regions was nonkeratinized

Phylogeny and biogeography of midwife toads (Alytes, Discoglossidae): a rebuttal

Three competing phylogenetic hypotheses for the genus Alytes (midwife toads) are evaluated. Based on quantitative coding of protein characters the most parsimonious solution shows a sister taxon relationship for Alytes dickhilleni and A. muletensis. The alternatives in which A. obstetricans has its sister group in either A. dickhilleni or A. muletensis lack support. Using calibrations derived from protein evolutionary rates, the vicariant events giving rise to A. obstetricans and the lineage leading to the A. muletensis and A. dickhilleni clade and the subsequent splitting between A. muletensis and A. dickhilleni cannot be placed much earlier than the Miocene-Pliocene boundary. Biogeographical scenarios invoking an earlier time of divergence should be rejected.

Number of Stock Plant Shoot Nodes Influences Splitting of `Lilo' Poinsettia

The influence of poinsettia (Euphorbia pulcherrima Wild. ex Klotzsch) stock plant shoot maturity on subsequent splitting of cuttings taken from the shoots was evaluated. Terminal cuttings (7.5 cm) taken from `Lilo' poinsettia stock plant axillary shoots that had 4, 8, or 12 nodes were rooted, planted, then observed for initial signs of splitting (conversion of the vegetative terminal buds into floral buds). The percentages of cuttings that split were 22, 77, and 100 for those taken from shoots with 4, 8, and 12 nodes, respectively. By implication, cuttings should be taken just as stock plant axillaries reach a size adequate for propagation to help reduce the incidence of splitting.

The pattern of vascular deployment near the pulvinus of the solar-tracking leaf of Lavatera cretica (Malvaceae)

Distinguishable files of xylem and phloem elements that originate in first-order branches of the seven palmate major veins of Lavatera cretica leaves become separated from files unique to the radially aligned sections of the same veins before entering the pulvinus at the distal end of the petiole. The major veins initially merge to form a double coaxial tube: the outer cylinder comprises files unique to the major veins and the inner cylinder comprises files from lateral branches. Subsequent splitting, unfolding, and recombining of these cylinders results in the single narrow flexible tube constituting the hinge of the pulvinus. Proximal to this point, in L. cretica, the files reseparate into six alternately large and small petiolar bundles. The observed vascular pattern offers a means whereby signals from the lamina that elicit sun-tracking movements by the pulvinus can be integrated.
