Records of 1 April snow water equivalent (SWE) are examined here using multiple linear regression against reference time series of temperature and precipitation. This method permits 1) an examination of the separate roles of temperature and precipitation in determining the trends in SWE; 2) an estimation of the sensitivity of...
Transcription factors with multiple post-translational modifications (PTMs) are not uncommon, but comprehensive information on site-specific dynamics and interdependence is comparatively rare. Assessing dynamic changes in the extent of PTMs has the potential to link multiple sites both to each other and to biological effects observable on the same time scale....
The intergenerational transmission of school adjustment was explored in a sample of 213 children and their fathers. The fathers were participants in a longitudinal study that began when they were in the fourth grade, and their children have been assessed at the ages of 21 months and 3, 5, and...
We give a randomized O(n polylog n)-time approximation scheme for the Steiner forest problem in the Euclidean plane. For every fixed ε > 0 and given n terminals in the plane with connection requests between some pairs of terminals, our scheme finds a (1 + ε) approximation to the minimum-length...
A snowpack model sensitivity study, observed changes of snow cover in the NOAA satellite dataset, and snow cover simulations from the Coupled Model Intercomparison Project phase 3 (CMIP3) multimodel dataset are used to provide new insights into the climate response of Northern Hemisphere (NH) snow cover. Under conditions of warming...
The authors have used a spectral, primitive equation mechanistic model of the stratosphere and mesosphere
to simulate observed stratospheric flow through the winters of 1991–92 and 1994–95 by forcing the model at
100 hPa with observed geopotential height. The authors assess the model’s performance quantitatively by
comparing the simulations with...
