Blue copper proteins (BCPs) comprise classic cases of Nature's profound control over the electronic structures and chemical reactivity of transition metal ions. Early studies of BCPs focused on their inner coordination spheres, that is, residues that directly coordinate Cu. Equally important are the electronic and geometric perturbations to these ligands provided by the outer coordination spher...

Nowadays with the ever-increasing growth in social media platforms and the creation of different forms of online activism, the word known as “Campaign” has become a familiar and useful term in people’s everyday lives. Campaigns with all kinds of social aims especially using Hashtags are run on social media platforms by individuals, charities, NGOs, governments, municipalities and brand companie...

Sphere mapping is a useful tool for creating realistic computer-generated images. It is currently the only view-dependent texture mapping technique widely supported in hardware. Understanding how sphere mapping relates to other environment mapping techniques such as parabolic mapping and cubic mapping can help promote its use in the appropriate context. After an initial survey of texture mappin...

Recent efforts have shown that the dynamic properties of a wide class of liquids can be mapped onto semi-universal scaling laws and constitutive relations that are motivated by thermodynamic analyses of much simpler models. In particular, it has been found that many systems exhibit dynamics whose behavior in state space closely follows that of soft-sphere particles interacting through an invers...

see through the wall radar, is a relatively new small range radar that uses electromagnetic waves to detect targets behind wall. because of its symmetry, a conducting sphere is often used as a reference scatterer to calibrate radars. in this paper, to simulate received signal for see through the wall radar, scattering model of a conducting sphere in free space is presented. then using a dielect...

The Avogadro constant has been determined by atom counting in two enriched 28Si spheres. Atoms were counted by exploiting their ordered arrangement in the spheres and calculating the ratio between sphere and the unit cell volumes. This paper describes how the values of the sphere lattice-parameters and, consequently, their unit-cell volumes, were obtained. PACS numbers: 06.20.-f, 06.20.Jr, 07.0...

New media have been widely used by radical groups of both Left and Right to advance their political projects. The aim of this article to provide a theoretical framework, through developing the concepts of public sphere and counter-public sphere, which allows us to understand the growing importance of alternative media in society and to indicate how this framework might generate questions for

In this note we compare even and odd fuzzy sphere constructions, their dimensional reductions and possible (M)atrix actions having them as solutions. We speculate on how the fuzzy 5-sphere might appear as a solution to the pp wave (M)atrix model.
