Juvenalia, or How I came to own a Blu-Ray of Point Break
No full textAgony Klub and Publication Studio Vancouver are pleased to present Whitney Houston, vol. 2. A continuation of Whitney Houston, et. al., editor/author Casey Wei invites six writers to reflect on their relationship to popular music in film, keeping in mind that popular music has always been as much about the desire for an image as about the catchiness of a song. The resulting essays on Elliot Smith, Amélie, Real Genius, The Pixies, Drive, and The Conversation explore themes of time, love, and evolution.final article publishedReal Genius (1985

Whitney Twins, Whitney Duals, and Operadic Partition Posets
No full textWe say that a pair of nonnegative integer sequences is Whitney-realizable if there exists a poset for
which (the absolute values) of the Whitney numbers of the first and second kind
are given by the numbers and respectively. The pair is said to be
Whitney-dualizable if, in addition, there exists another poset for which
their Whitney numbers of the first and second kind are instead given by
and respectively. In this case, we say that and are Whitney
duals. We use results on Whitney duality, recently developed by the first two
authors, to exhibit a family of sequences which allows for multiple
realizations and Whitney-dual realizations. More precisely, we study edge
labelings for the families of posets of pointed partitions
and weighted partitions which are associated to the operads
and respectively. The first author and Wachs
proved that these two families of posets share the same pair of Whitney
numbers. We find EW-labelings for and and use
them to show that they also share multiple nonisomorphic Whitney dual posets.
In addition to EW-labelings, we also find two new EL-labelings for
answering a question of Chapoton and Vallette. Using these
EL-labelings of , and an EL-labeling of introduced by
the first author and Wachs, we give combinatorial descriptions of bases for the
operads and . We
also show that the bases for and are PBW

Equivariant Stiefel-Whitney classes
No full textAbstractWe develop a theory of equivariant Stiefel-Whitney classes for equivariant orthogonal vector bundles over schemes, parallel to Grothendieck's theory of equivariant Chern classes for equivariant linear vector bundles. We apply it to generalise earlier results on characteristic classes of ‘trace forms’, due to Serre, Fröhlich, Snaith, Jardine, Esnault, Viehweg and the author

Invasion of Brachypodium sylvaticum in prairie and forest habitats : differences in community structure between uninvaded and invaded systems in Bald Hill Park, Corvallis, Oregon
No full textBrachypodium sylvaticum (Huds.) Beauv. is an invasive grass that can be found in forest
and prairie communities throughout the Willamette Valley, Oregon. It can out-compete
native species of grasses and forbs and become dominant in a broad range of habitats.
This study investigated if there were differences in vegetation structure between
communities that were not invaded by B. sylvaticum and communities that were invaded.
The study took place in Bald Hill Park, Corvallis, Oregon, and prairie and forest habitats
were analyzed separately. Percent cover of B. sylvaticum and eight other vegetation or
substrate types were used to assess community structure. Prairie habitats showed
considerable differences in vegetation structure, particularly in cover of grasses (other
than B. sylvaticum), forbs, and bare ground. Brachypodium sylvaticum can decrease
quality of forage for wildlife, or displace endemic species of plants, some of which are
endangered. Control of the invasive grass is important for the survival of endangered
plant or insect species. At the levels of invasion in this study, forest habitats did not show
much change in community structure, which was surprising. The lack of detectable
differences may be due to small sample size or insufficient levels of invasion of B.
