A graph is an opposition graph, respectively, a coalition graph, if it admits an acyclic orientation which puts the two end-edges of every chordless 4-vertex path in opposition, respectively, in the same direction. Opposition and coalition graphs have been introduced and investigated in connection to perfect graphs. Recognizing and characterizing opposition and coalition graphs are long-standin...

INTRODUCTION In classic mechanics, degrees of freedom (DOF) are defined as the minimum number of independent coordinates needed to describe a system’s position. The human musculoskeletal system has many mechanical DOF through which countless movements are accomplished. However, natural movements are characterized by the coordination of the DOF such that few vary independently. The concept of fu...

My goal in this paper is to use cross-polar anomaly as an empirical basis for motivating and developing a particular approach to the semantics of gradable adjectives and the representation of adjectival polarity. Specifically, I will argue that gradable adjectives denote relations between individuals and extents, or intervals on a scale, as in the work of Seuren 1978, 1984, von Stechow 1984b, a...
