Let p( yl, y2 1 X) denote a discrete memoryless channel with a single source X and two independent receivers YI and Y2. W e exhibit an achievable region of rates (R11,R12,R22) at which independent information can be sent, respectively, to receiver 1, to both receivers 1 and 2, and to receiver 2. The achievability of the region is shown by using a version of the asymptotic equipartit ion propert...

We investigate the effects that regional start-up activity has on employment in new and in incumbent businesses. The analysis is performed for West German regions over the 1987-2002 period. It shows that the effects of new businesses on employment in the incumbents are significantly positive and that this indirect effect on incumbent employment leads to more jobs than what is created by the new...

Motivated by the recent experimental observations @Phys. Rev. B 57, R11 051 ~1998!# of transverse spin ordering in FeBr2 induced by a magnetic field with oblique angle to the easy axis of the system, we performed extensive Monte Carlo simulations of a classical anisotropic Heisenberg model. We have calculated the specific heat and the parallel and perpendicular components of the magnetization a...

Adopting a time series convergence definition and panel unit root testing procedures, we fail to reject the null hypothesis of no convergence in GDP per capita across former West German states. This result stands in contrast to the findings of previous studies for West German regions using cross-section regression techniques and is contrary to the time series findings for the United States. Fro...

Aminoglycoside 3'-phosphotransferases I and II in three strains of Pseudomonas aeruginosa were studied in comparison with those in two strains of R factor-carrying Escherichia coli. The strain TI-13 of P. aeruginosa produced the former and strain H-9 the latter. Strain B-13 produced the both enzymes. The 3'-phosphotransferases of type I in P. aeruginosa TI-13, B-13 and E. coli K12 J5 R11-2 were...

How important is access to patent documents for subsequent innovation? We examine the expansion of USPTO Patent Library system after 1975. libraries provided patents before Internet. find that library opening, local patenting increases by 8–20 percent relative similar regions. Additional analyses suggest disclosure technical information drives this effect: inventors increasingly take up ideas f...

abstract governments in regional and national level try to improve economic and productivity growth by different polices. the being aware of effective factors in national and regional economic and productivity growth is essential for government success. in this paper, to being of aware determinant factors in productivity inequality, we use decomposition approach and econometric estimation for 2...
