The Fermi Large Area Telescope (LAT) has provided the most detailed view to date of the emission toward the Galactic center (GC) in high-energy γ-rays. This paper describes the analysis of data taken during the first 62 months of the mission in the energy range 1–100 GeV from a 15° × 15° region abou ...

We theoretically study the electrokinetic problem of a pressure-induced liquid flow through a narrow long channel with charged walls, going beyond the classical Helmholtz-Schmolukowski picture by considering the surprisingly strong combined effect of (i) Stern-layer conductance and (ii) dynamic char ...

Single crystals of GaN < 3 mm in length were grown by sublimation/recondensation of GaN in 760 Torr ▫$NH_3$▫ at 1100°C. Platelets of AlN < 1 mm thick were similarly grown between 1950 and 2250°C using an Al source. Monocrystalline GaN and ▫$Al_xGa_{1-x}N$▫(0001)(0.05 < x < 0.96) films were grown via ...
