Over the last thirty years, the phenomenon of polarity sensitivity has proven both a touchstone and a stumbling block for theories of grammatical representation. Unfortunately, an abundance of scrutiny does not always guarantee an increase in insight. Two major pitfalls are worth mentioning. On the one hand, as the theorist strives for intimations of universality, the complexity and subtle vari...

Polar graphs are a common generalization of bipartite, cobipartite, and split graphs. They are defined by the existence of a certain partition of vertices, which is NPcomplete to decide for general graphs. It has been recently proved that for cographs, the existence of such a partition can be characterized by finitely many forbidden subgraphs, and hence tested in polynomial time. In this paper ...

This research revisits plot units, which were developed in the 1980s as a conceptual knowledge structure to represent the affect states of and emotional tensions between characters in narrative stories. We present a fully automated system, called AESOP, that generates plot unit representations for narrative texts. AESOP performs four steps: affect state recognition, character identification, af...

Received medical services are increasingly discussed and recommended on physician rating websites (PRWs). The reviews and ratings on these platforms are valuable sources of information for patient opinion mining. In this paper, we have tackled three issues that come along with inconsistency analysis on PRWs: (1) Natural language processing of user-generated reviews, (2) the disagreement in pola...

agricultural drought in iran is considered as a natural disaster especially for the farmers. although nobody can stop drought, but if its nature and its characteristics are studied, it can be predicted and the results can be reduced. this article studies drought in the province of sistaan and balouchestaan and the drought predictability in the province has been done base on a model that is made...

The composition of a landscape is a fundamental indicator in land-cover pattern assessments. The objective of this paper was to evaluate a landscape composition indicator called 'landscape mosaic' as a framework for interpreting land-cover dynamics over a 9-year period in a 360,000 km2 study area in the southern United States. The indicator classified a land parcel into one of 19 possible lands...

Dahlia pinnata is a species of the genus dahlia, belonging to the family Asteraceae. The present study reported the use of dahlia pinnata flower extract as an acid base indicator in different types of acid base titrations. The equivalence point obtained by the flower extract coincided with the equivalence point obtained by standard indicators. The results obtained by the flower extract matched ...

Inadequate knowledge of baseline conditions challenges ability for monitoring programs to detect pollution in rivers, especially where there are natural sources of contaminants. Here, we use paleolimnological data from a flood-prone lake ("SD2", informal name) in the Slave River Delta (SRD, Canada), ∼ 500 km downstream of the Alberta oil sands development and the bitumen-rich McMurray Formation...
