Quantifying alpha, beta and gamma geodiversity

Alpha Beta and Gamma Radiation Lab

Unstable atomic nuclei may decay into less energetic nuclei by emission of alpha, beta, and gamma radiation. These forms of radiation are now known to consist of He4 nuclei, electron (or positron), and high energy photons respectively. Which types of decay a nuclei may undergo depends on how it is unstable. Many materials may emit more than one form of radiation. This is especially true when th...

Alpha, beta-and gamma-secretases in Alzheimer's disease.

Generation of Amyloid peptide (Abeta) is at the beginning of a cascade that leads to Alzheimer's disease. Currenty, the mechanisms of Abeta generation and Abeta prevention are subject of intensive research. Amyloid precursor protein (APP), as well as beta- and gamma-secretases are the principal players involved in Abeta production, while alpha-secretase cleavage on APP prevents Abeta deposition...

Design of Adaptive Alpha-Beta-Gamma Filters with Fuzzy Systems

The α β γ filter is an efficient estimation scheme for the motion control. According to the estimated position, velocity and acceleration signals which are provided by the α β γ filters, motion objects will be able to result in an excellent control. However, the estimation performance heavily depends on the parameters α , β and γ . This paper presents a fuzzy logic system to develop an adaptive...

Surface expression of only gamma delta and/or alpha beta T cell receptor heterodimers by cells with four (alpha, beta, gamma, delta) functional receptor chains

Surface expression of TCR dimers by cells synthesizing three or four distinct types of receptor chains was analyzed. Cells containing intact gamma, alpha, and beta chains had only gamma delta dimers on the cell surface. In human PEER cells, addition of a functional alpha chain led to the loss of gamma delta dimer expression and expression of only alpha beta dimers. This result was not due to tr...
