High-dimensional self-exciting point processes have been widely used in many application areas to model discrete event data which past and current events affect the likelihood of future events. In this paper, we are concerned with detecting abrupt changes coefficient matrices discrete-time high-dimensional Poisson processes, yet be studied existing literature due both theoretical computational ...

The pore size, shape and orientation of an illite-dominant clay were mapped during one-dimensional compression, using mercury intrusion porosimetry (MIP), scanning electron microscopy gas adsorption. total porosity was found to spread over the three International Union Pure Applied Chemistry classes pores sizes: micropores (below 2 nm), mesopores (2–50 nm) macropores (above 50 all observed comp...

Introduction The use of cut-outs in electron applicators make changes on output, isodose, and percentage depth dose (PDD) curves. These changes and electron beam dose distribution in the form of three-dimensional (3D) can be measured by gel dosimeters. Materials and Methods Dosimetry was performed with and without a square shield (6×6 cm2 field). The energies were 4, 9, and 16 MeV and phantom w...
