[1] Longitudinal profiles from six alluvial fans surveyed in southwestern California have quantitative attributes that can distinguish formation processes. The radial slope of fans where debris flow processes dominated is constant while fluvially-fed fans have a concave-upward shape. We find the power law regression of upstream slope-distance profiles is the preferred approach for assessing con...

The study of sport spectatorship has an increasing focus on the importance of fandom beyond fan violence. Fundamental to understanding fan behavior are the meaningful rituals and emotions experienced by fans. In this paper, I use the theoretical work of Randall Collins to examine the ritualistic outcomes of collective effervescence, emotional energy, and group symbols and solidarity among sport...

Bustling around their reef homes, Red Sea dascyllus damselfish (Dascyllus marginatus) do quite well out of their co-habiting arrangement with hood coral (Stylophora pistillata). ‘The coral provide the fish with shelter from predators and a place for social interactions and egg laying’, says Nur Garcia-Herrera, from the Alfred-Wegener-Institut, Germany. Yet the agreement isn’t entirely one sided...

We propose an algorithm for computing the facets of a pure connected polyhedral fan up to symmetry. The fan is represented by an oracle. With suitable implementations of the oracle the same algorithm can be used for computing secondary fans, Gröbner fans, Tropical varieties and Minkowski sums up to symmetry. The algorithm has been implemented in the software Gfan.

The article considers the peculiarities of strategies behavior fans in Soviet stadiums postwar period. On example city Kyiv and “Republican” stadium, an analysis competition between officially permitted, acceptable models alternatives to them, which took place during football matches, is conducted. stadium matches was a kind point “inaccessibility” for authorities. Watching at accompanied by mo...

The goal of this paper is to show that the local Gröbner fan is a polyhedral fan for ideals in the ring of power series and the homogenized ring of analytic differential operators. We will also discuss about relations between the local Gröbner fan and the (global) Gröbner fan for a given ideal and algorithms of computing local Gröbner fans. In rings of differential operators, finiteness and con...
