We formalize the treatment of directed (or chiral) quantum walks using Hermitian adjacency matrices, bridging two developing fields research in information and spectral graph theory. display results simulations which highlight conceptual differences between having directions encoded Hamiltonians or not. This leads to a construction new type phenomenon: zero transfer pairs sites connected couple...

The present study, on the one hand, attempted to investigate the strategies applied in dispreferred responses by Iranian university students of English and the extent to which pragmatic transfer could occur.  On the other hand, the study aimed to probe into the association between dispreferred organization and turn-shape. To this end, 31 relevant naturally occurring conversations, totaling 120 ...

A cusp singularity is a surface whose minimal resolution cycle of smooth rational curves meeting transversely. Cusp singularities come in naturally dual pairs. Looijenga proved 1981 that if smoothable, the anticanonical divisor some surface. In 1983, second author and Miranda gave criterion for smoothability singularity, terms existence K-trivial semistable model central fiber such smoothing. W...

Region merging methods consist of improving an initial segmentation by merging some pairs of neighboring regions. In a graph, merging two regions is not straightforward. The perfect fusion graphs defined in [J. Cousty et al, “Fusion Graphs: Merging Properties and Watersheds”, JMIV 2008] verify all the basic properties required by region merging algorithms as used in image segmentation. Unfortun...

Region merging methods consist of improving an initial segmentation by merging some pairs of neighboring regions. In a graph, merging two regions is not straightforward. The perfect fusion graphs defined in a previous paper verify all the properties requested by region merging algorithms. In this paper, we present a theorem which states that, in any dimension, the perfect fusion grids introduce...

The present work introduces MoralConvITA, the first Italian corpus of conversations on Twitter about immigration whose annotation is focused how moral beliefs shape users interactions.The currently consists a set 1,724 tweets organized in adjacency pairs and annotated by referring to pluralistic social psychology theory values, i.e. Moral Foundations Theory (MFT). According MFT, different confi...

This paper describes a multi-modal corpus of hand-annotated meeting dialogues that was designed for studying addressing behavior in face-to-face conversations. The corpus contains annotated dialogue acts, addressees, adjacency pairs and gaze direction. First, we describe the corpus design where we present the annotation schema, annotation tools and annotation process itself. Then, we analyze th...

Question 1 First, we have that λ − λ − 2 = (λ + 1)(λ − 2). Therefore, it is true that the eigenvalues of the corresponding adjacency matrix come in pairs of additive inverse. However, notice that ± √ −1 are eigenvalues, and therefore the associated matrix cannot be symmetric (there would only be real eigenvalues). We conclude that no undirected graph can have the above characteristic polynomial...

The hypothesis was proposed, that the perceived depth, which results from the relative height cue, depends on "optical adjacency." A 3 X 3 factorial experiment was conducted to examine this hypothesis. The 2 factors were vertical separation (3.5, 5.5, 7.5 in.) and background conditions (0 background, outline background without surface texture, textured background). Verbal estimates of the depth...
