We have characterized the spectra and performance of an ensemble of eleven fiber–coupled laser diode arrays (LDAs) manufactured by Opto Power Inc. These high–power LDAs operate near 795 nm and are of a type commonly used for spin–exchange optical pumping of noble gases. We find the Opto Power LDAs to vary significantly in output power, spectral width, and other important characteristics, in a m...

Kruppel-like factor 6 (KLF6) is a tumor suppressor gene inactivated in prostate and colon cancers, as well as in astrocytic gliomas. Here, we establish that KLF6 mediates growth inhibition through an interaction with cyclin D1, leading to reduced phosphorylation of the retinoblastoma protein (Rb) at Ser(795). Furthermore, introduction of KLF6 disrupts cyclin D1-cyclin-dependent kinase (cdk) 4 c...

A new ultrahigh vacuum-compatible ( 10 11 mbar) "reaction microscope" was built to investigate multiple ionization of atoms and molecules in ultra-short (23 fs), intense laser pulses (1014 1016 W/cm2, 795 nm) . In first experiments ion momentum distributions for single and double ionization of noble gas atoms in the nonsequential and sequential intensity regime were measured using linearly pola...

Were the new economic geography forces for industry agglomeration and dispersion at work in the movement of industry in pre-1931 Britain where transport costs were falling? This paper examines the issue empirically using a general model that nests the Heckscher-Ohlin factor endowment with new economic geography models. The evidence suggests that while the location of pre-1931 British industry w...

A graph G is a 2-tree if G = K3, or G has a vertex v of degree 2, whose neighbors are adjacent, and G − v is a 2-tree. Clearly, if G is a 2-tree on n vertices, then |E(G)| = 2n − 3. A non-increasing sequence π = (d1, . . . , dn) of nonnegative integers is a graphic sequence if it is realizable by a simple graph G on n vertices.
