The full 4D array is divided into two subarrays and the differential evolution (DE) algorithm is used to optimize the time sequence of each subarray to generate multibeams at the center frequency and low sidebands. Then the multibeams of the two subarrays are phase-compared with each other ...
Leukemia is a malignant disorder of the bone marrow. Broadly, leukemias may be divided into acute leukemias (a rapid clinical course with a high level of blasts in the bone marrow) and chronic leukemias (more insidious clinical course with fewer blasts in the bone marr...
The method of difference potentials was originally proposed by Ryaben'kii and can be interpreted as a generalized discrete version of the method of Calderon's operators in the theory of partial differential equations. It has a number of important advantages; it easily handles curvilinear boundaries,...
It is known that a large class of such processes diverges with positive probability, and when properly normalized converges almost surely or converges in distribution to a normal or a lognormal distribution. Here we find a class of processes that when properly normalized converges in distribution ...

The idea of the support operator method is to approximate one of the differential operators (div or grad) directly, while the other is approximated to satisfy the difference analogue of the integral identity ∫Ω udivp dV=∫ Ω up ds-∫ Ω (p ,gradu)dV· The convergence of the difference...
