The internationalization of internet governance

Starting from 1998, the government of the United States took up responsibility for creating and overseeing the Internet Corporation for Assigned Names and Numbers. That Corporation manages the global infrastructures of identifiers on the internet. Beginning with 2003, the United Nations has addressed lack of internationalized co- ordination mechanisms in managing critical global internet infrastructures through World Summit on the Information Society and Internet Governance Forum. Those who are engaged with the Forum’s Global Internet Governance negotiation, as of 2009, are divided into two groups: those who demand immediate change including the government of China; and those who support gradual change without discussing when and how such change can take place.Technology, Policy and Managemen

Roadmap on digital holography-based quantitative phase imaging

Quantitative Phase Imaging (QPI) provides unique means for the imaging of biological or technical microstructures, merging beneficial features identified with microscopy, interferometry, holography, and numerical computations. This roadmap article reviews several digital holography-based QPI approaches developed by prominent research groups. It also briefly discusses the present and future perspectives of 2D and 3D QPI research based on digital holographic microscopy, holographic tomography, and their applications.ImPhys/Imaging PhysicsImPhys/Computational ImagingIndustrial Design Engineerin
