Climate change at the ecosystem scale: a 50-year record in New Hampshire [PDF]

open access: yes, 2012
Observing the full range of climate change impacts at the local scale is difficult. Predicted rates of change are often small relative to interannual variability, and few locations have sufficiently comprehensive long-term records of environmental ...

Novikov algebras and a classification of multicomponent Camassa-Holm equations [PDF]

open access: yes, 2014
A class of multi-component integrable systems associated to Novikov algebras, which interpolate between KdV and Camassa-Holm type equations, is obtained. The construction is based on the classification of low-dimensional Novikov algebras by Bai and Meng.

Fossil group origins - VI. Global X-ray scaling relations of fossil galaxy clusters [PDF]

open access: yes, 2015
We present the first pointed X-ray observations of 10 candidate fossil galaxy groups and clusters. With these Suzaku observations, we determine global temperatures and bolometric X-ray luminosities of the intracluster medium (ICM) out to $r_{500}$ for ...

Birational properties of some moduli spaces related to tetragonal curves of genus 7

open access: yes, 2011
Let M_{7,n} be the (coarse) moduli space of smooth curves of genus 7 with n marked points defined over the complex field. We denote by M^1_{7,n;4} the locus of points inside M_{7,n} representing curves carrying a g^1_4.
