This paper describes measurements and simulations related to power fluctuations of the laser light in the GEO 600 laser-interferometric gravitational wave detector. Measurements of the relative fluctuations of the light power at three different ports of the main interferometer are presented. In addition, measurements and simulations of the coupling transfer functions from power fluctuations at ...

Minkowski and Ochs have recently argued that the small two photon coupling of a conjectured σ(600) is so small that it is likely to be a glueball. We ask whether this can be so or whether it is simply gauge invariance that produces the observed low mass suppression?

We study the a0 and σ mesons with the overlap fermion in the chiral regime with the pion mass as low as 182MeV in the quenched approximation. After the ηN ghost states are separated, we find that the a0 mass with qq̄ interpolation field to be almost independent of the quark mass in the region below the strange quark mass. The chirally extrapolated results are consistent with a0(1450) being the u...

1 Abstract The DECNIS 500/600 high-performance multiprotocol bridge/router and gateway are described. The issues affecting the design of routers with this class of performance are outlined, along with a description of the architecture and implementation. The system described uses a distributed forwarding algorithm and a distributed buffer management algorithm executed on plug-in linecards to ac...

The circuit techniques used to implement a 600MHz, out-of-order, superscalar RISC Alpha microprocessor are described. Innovative logic and circuit design created a chip that attains 30+ SpecInt95 and 50+ SpecFP95, and supports a secondary cache bandwidth of 6.4GB/s. Microarchitectural techniques were used to optimize latencies and cycle time, while a variety of static and dynamic design methods...

The founding fathers of grounded theory (GT) claimed it is an inductive methodological approach. Yet, some scholars argue that purely inductive GTs are not possible given researchers’ involvement in data collection and analysis. Subsequently, a constructivist GT approach was introduced. Still, full-length methodological articles that include rationales or detailed explanations for using constru...

In this paper we study some causes and consequences of founder-CEO replacements among a sample of 4,172 Danish startups created by single founders in 1999 and 2000. In contrast to the extant literature on VC-financed firms, replacements among firms in our sample are more likely among the worstand best-performing firms, and replacement is not unambiguously associated with better subsequent perfo...

A Theory of Expert Leadership How much knowledge should leaders have of their organization’s core business? This is an important question but not one that has been addressed in the management literature. In a new ‘theory of expert leadership’ (TEL), this paper blends conceptual work with recent empirical evidence. It suggests that organizations perform more effectively when led by individuals w...

We content analyzed CEO communications of a large MNC to examine the values that constitute its organizational identity and surveyed 4530 stakeholders to identify global and local managerial roles. Findings suggest that MNC CEO endorsed global culture values integrating local culture with company values that manifest in mid-level managers’ roles.
