Mountain regions are highly sensitive to global climate change. However, large scale assessments of mountain environments remain problematic due to the high resolution required of model grids to captu...
Fermi Large Area Telescope Observations of the Active Galaxy 4C +55.17: Steady, Hard Gamma-Ray Emission and its Implications
Steady Hard Gamma-Ray Emission Implications
2011/9/29
We report Fermi/LAT observations and broad-band spectral modeling of the radio-loud active galaxy 4C +55.17 (z=0.896), formally classified as a flat-spectrum radio quasar. Using 19 months of all-sky s...

2010/11/9
We report on the search for 0.1{10 GeV emission from magnetars in 17 months of Fermi Large
Area Telescope (LAT) observations. No signi cant evidence for gamma-ray emission from any of the currently-k...
Growth of Large-Area Graphene Films from Metal-Carbon Melts
Single Layer Graphene Crystal Growth Binary Phases Raman Spectroscopy wrinkles
2010/11/24
We have demonstrated a new method for the large-area graphene growth, which can lead to a scalable low-cost high-throughput production technology. The method is based on growing single-layer or few-la...
Spatial Non-uniformity Measurements of Large Area Silicon Photodiodes
Photometry Silicon Photodiode Spatial Uniform
2010/4/13
Accurate determination of the responsivity of silicon photodiodes are highly desired in photometry. The change of responsivity over the surface, the so-called spatial non-uniformity, effects power mea...
The First Catalog of Active Galactic Nuclei Detected by the Fermi Large Area Telescope

2010/3/9
We present the first catalog of active galactic nuclei (AGN) detected by the LAT, corresponding to 11 months of data collected in scientific operation mode. The First LAT AGN Catalog (1LAC) includes 6...
Testing the transferability of regression equations derived from small sub-catchments to a large area in central Sweden
water balance modelling large scale multiple regression
2009/3/12
There is an ever increasing need to apply hydrological models to catchments where streamflow data are unavailable or to large geographical regions where calibration is not feasible. Estimation of mode...
