Human 3-D tissue models in radiation biology: current status and future perspectives

In this review, we discuss the use of a variety of 3-D models (particularly 3-D skin, lung, breast and endothelial) in radiobiological research and highlight the differences in responses compared to 2-D culturing conditions (monolayers). We review the characteristics of existing 3-D models and aim to point out the substantial advantages 3-D cultures provide for modern radiobiology. In particula...

1 OV / 3 - 3 Overview of Physics Results from MAST

Major plant and diagnostic developments on MAST have enabled important advances in support of ITER, definition of a component test facility (CTF) and the clarification of underlying tokamak physics. For example, L-H transition studies benefit from high spatial and temporal resolution measurements of pedestal profile evolution (temperature, density and radial electric field) and in support of pe...

Stabilizing the invisible axion in 3-3-1 models

Recently, observations of the core mass distribution in the cluster of Galaxies Abell 2029 using the NASA’s Chandra X-ray Observatory suggest the existence of cold dark matter (CDM) [1]. On the other hand, the Wilkinson Microwave Anisotropy Probe (WMAP) measurements of the cosmic microwave background temperature anisotropy and polarization are also consistent with CDM and a positive cosmologica...

3-3-1 Models at Electroweak Scale

We show that in 3-3-1 models there exist a natural relation among the SU(3)L coupling constant g, the electroweak mixing angle θW , the mass of the W , and one of the vacuum expectation values, which implies that those models can be realized at low energy scales and, in particular, even at the electroweak scale. So that, being that symmetries realized in Nature, new physics may be really just a...
