Whether they are modeling bookmarking behavior in Flickr or cascades of failure in large networks, models of diffusion often start with the assumption that a few nodes start long chain reactions, resulting in large-scale cascades. While reasonable under some conditions, this assumption may not hold for social media networks, where user engagement is high and information may enter a system from ...

This is the seventh edition of the Colorado State University (CSU)-CHILL newsletter which we distribute on an annual basis, near the start of the academic year. The newsletter is intended to provide information to the community regarding research, education, and refurbishment activities of the CSUCHILL facility. In April 1995 Colorado State University was awarded a second five-year Cooperative ...

Valuable models for immortal solutions of Ricci ‡ow that collapse with bounded curvature come from locally G-invariant solutions on bundles GN ,! M !Bn, with G a nilpotent Lie group. In this paper, we establish convergence and asymptotic stability, modulo smooth …nite-dimensional center manifolds, of certain RN -invariant model solutions. In case N + n = 3, our results are relevant to work of ...

We show that, by using resummation techniques based on the extension of the methods of Yennie, Frautschi and Suura to Feynman’s formulation of Einstein’s theory, we get calculable loop corrections that are even (superficially) free of UV divergences. The UV finiteness of the loops results from resumming large IR terms O(GN|k 2 |ln|k 2 |) n , n = 1,..., for |k 2 | , where GN is Newton’s constant...

This study investigated the discourse effects on intermediate English as foreign language (EFL) learners’ production of dative constructions including prepositional dative (PD), I gave a book to John, and double-object dative (DOD), I gave John a book. The author argues that the alternation between these two constructions is determined by the order of given and new (GN) information that is foll...

In the papers [FS1], [FS2] we described some Siegel modular threefolds which admit a weak Calabi–Yau model.*) Not all of them admit a projective model. In fact, Bert van Geemen, in a private communication, pointed out a significative example which cannot admit a projective model. His comment was a starting motivation for this paper. We mention that a weak Calabi–Yau threefold is projective if, ...

If a linear program tLP) possesses a large generalized network (G N) submatrix, this structure can be exploited to decrease solution time. The problems of finding maximum sets of GN constraint s and finding maximum embedded GN sub matrices are shown to be NP-complete, indicating that reliable, efficient solution of these problems is difficult. Therefore, efficient heuristic algorithms are devel...

We write the thermodynamic Bethe ansatz for the massive OSp(2|2) Gross Neveu and sigma models. We find evidence that the GN S matrix proposed by Bassi and Leclair [12] is the correct one. We determine features of the sigma model S matrix, which seem highly unconventional; we conjecture in particular a relation between this sigma model and the complex sine-Gordon model at a particular value of t...
