Introduction: The main goal of SPECT imaging is to determine activity distribution inside the organs of the body. However, due to photon attenuation, it is almost impossible to do a quantitative study. In this paper, we suggest a mathematical relationship between activity distribution and its corresponding projections using a transfer matrix. Monte Carlo simulation was used to find a precise tr...

I construct a global version of the local polysymplectic approach to covariant Hamiltonian field theory pioneered by C. Gunther. Beginning with geometric framework theory, specialize vertical vector fields (poly)symplectic structures, derive Hamilton's equations, and more-or-less natural Poisson bracket. then examine few key examples determine nature necessary projections find that provides ana...

Posterior distributions for the joint projections of future temperature and precipitation trends and changes are derived by applying a Bayesian hierachical model to a rich dataset of simulated climate from Global Circulations Models. The simulations here analyzed constitute the most reliable future projections on which the Intergovernmental Panel of Climate Change based its recent summary repor...
