Spill Your (Trade) Secrets: Knowledge Networks as Innovation Drivers
Theories of intellectual property take the individual inventor or the firm as the unit of innovation. But studies in economic sociology show that in complex fields where knowledge is rapidly advancing and widely dispersed among different firms, the locus of innovation is neither an individual nor a single firm. Rather, innovative ideas originate in the informal networks of learning and collabor...
متن کاملBinary Star Measurements with the Star re
Four binaries, 10 UMa, UMa, 81 Cnc, and UMa, were observed with adaptive optics on the 3.5m telescope at the Starrre Optical Range on March 24, 1998, in order to investigate the relative photometry produced by adaptive optics within the isoplanatic patch. Iterative Blind Deconvolution (IBD) and Parametric Blind Deconvolution (PBD) techniques were used to post-process the data, and produced cons...
متن کاملBinary Neutron Star Mergers
We review the current status of studies of the coalescence of binary neutron star systems. We begin with a discussion of the formation channels of merging binaries and we discuss the most recent theoretical predictions for merger rates. Next, we turn to the quasi-equilibrium formalisms that are used to study binaries prior to the merger phase and to generate initial data for fully dynamical sim...
متن کاملStellar collisions during binary–binary and binary–single star interactions
Physical collisions between stars occur frequently in dense star clusters, either via close encounters between two single stars, or during strong dynamical interactions involving binary stars. Here we study stellar collisions that occur during binary–single and binary–binary interactions, by performing numerical scattering experiments. Our results include cross sections, branching ratios, and s...
متن کاملAn electrically powered binary star?
We propose a model for stellar binary systems consisting of a magnetic and a non-magnetic white-dwarf pair which is powered principally by electrical energy. In our model the luminosity is caused by resistive heating of the stellar atmospheres due to induced currents driven within the binary. This process is reminiscent of the Jupiter-Io system, but greatly increased in power because of the lar...
