Firms make investments in technology to increase productivity. But in emerging markets, where a culture of informality is widespread, information technology (IT) investments leading to greater transparency can impose a cost through higher taxes and need for regulatory compliance. This tendency of firms to avoid productivity-enhancing technologies and remain small to avoid transparency has been ...

Naming transparencies, i.e., abstracting the name and binding of the entity being used from the endpoints that are actually doing the work, are used in distributed systems to simplify application development by hiding the complexity of the environment. In this paper we demonstrate how to apply traditional distributed systems naming and binding techniques in the Web Services realm. Specifically,...

Transparency in 3D graphics has traditionally been created by ordering the transparent objects from back-to-front with respect to the viewpoint, and rendering the opaque objects first and then the transparent objects in the prescribed order. This has three major disadvantages: need for splitting intersecting polygons, repeated ordering for varying view points, and finally, incorrect transparenc...

We show how the application of a coupling field connecting the two lower metastable states of a Lambda system facilitates stoppage of light in a coherently driven Doppler broadened atomic medium via electromagnetically induced transparency.

Theoretical description of the ferromagnetic π-junctions near the critical temperature Abstract The theory of ferromagnetic π-junction near the critical temperature is presented. It is demonstrated that in the dirty limit the modified Usadel equation adequately describes the proximity effect in ferromagnets. To provide the description of an experimentally relevant situation, oscillations of the...

Participatory design approaches are being increasingly employed for designing digital artefacts and information systems with and for local communities. These cases require a reconceptualization of PD processes to account for widened knowledge gaps between designers and community members, and new patterns of community-defined design goals. In this paper we provide a perspective on the design pro...

The objective of this study is to find an effective stimulation and measurement strategy to improve distinguishability for head EIT. To better understand the relationship between distinguishability and various strategies (stimulation/measurement patterns) for a set of electrodes, we evaluated a realistic head model and a range of common strategies.

In this manuscript we present calculations that consider the propagation of a squeezed vacuum signal field through a resonant atomic medium under electromagnetically induced transparency (EIT). We show that squeezing is degraded due to four-wave mixing processes at high optical depth of the atomic medium. We also present some preliminary results for degenerate Zeeman EIT resonances.

In recent years there has been widespread concern in the scientific community over a reproducibility crisis. Among the major causes that have been identified is statistical: In many scientific research the statistical analysis (including data preparation) suffers from a lack of transparency and methodological problems, major obstructions to reproducibility. The revisit package aims toward remed...
