Weighted Composition Operators From Logarithmic Bloch-Type Spaces To Bloch-Type Spaces
The boundedness and compactness of the weighted composition operators from to Bloch-type spaces are studied here. © 2009 S. Stević and R. P. Agarwal.
Advanced Discrete Halanay-Type Inequalities: Stability of Difference Equations
We derive new nonlinear discrete analogue of the continuous Halanay-type inequality. These inequalities can be used as basic tools in the study of the global asymptotic stability of the equilibrium of certain generalized ...

The white dwarfs within 20 parsecs of the sun: Kinematics and statistics
We present the kinematical properties, distribution of spectroscopic subtypes, and stellar population subcomponents of the white dwarfs within 20 pc of the Sun. We find no convincing evidence of halo white dwarfs in the ...
Solutions of a system of integral equations in Orlicz spaces
We consider the following system of integral equations Ui(t) = ∫1gi(t,s)fi(s,u1(s),u2(s),...,un(s))ds, a.e. t [0,1], 1 ≤ i ≤ n. Our aim is to establish criteria such that the above system has a solution (u±,U2,... ,un) ...
Spectral dependence of terrestrial gamma-ray flashes on source distance
We use lightning sferics from the World Wide Lightning Location Network to identify storms near 362 Terrestrial Gamma-ray Flashes (TGFs). The combined spectrum of TGFs with storms within 300 km of the sub-satellite point ...
HST/ACS emission line imaging of low-redshift 3CR radio galaxies. I. The data
We present 19 nearby (z < 0.3) 3CR radio galaxies imaged at low and high excitation as part of a Cycle 15 Hubble Space Telescope (HST) snapshot survey with the Advanced Camera for Surveys (ACS). These images consist of ...
Photon-hadron jet correlations in p+p and Au+Au collisions at √sNN = 200 GeV
We report the observation at the Relativistic Heavy Ion Collider of suppression of back-to-back correlations in the direct photon+jet channel in Au+Au relative to p+p collisions. Two-particle correlations of direct photon ...
Initiating chromosome replication in E. coli: It makes sense to recycle
Initiating new rounds of Escherichia coli chromosome replication requires DnaA-ATP to unwind the replication origin, oriC, and load DNA helicase. In this issue of Genes & Development, Fujimitsu and colleagues (pp. 1221-1233) ...
Measurement of bottom versus charm as a function of transverse momentum with electron-hadron correlations in p+p Collisions at s=200GeV
The momentum distribution of electrons from semileptonic decays of charm and bottom quarks for midrapidity jyj < 0:35 in p þ p collisions at ffiffi s p ¼ 200 GeV is measured by the PHENIX experiment at the Relativistic ...
