Extrapulmonary small cell carcinoma of the stomach is a rare and aggressive malignancy with a poor prognosis that was first described in 1976 by Matsusaka et al. In 1989 it was recognized by the World Health Organization as an independent entity affecting the stomach. Pure and composite are the two types of gastric small cell carcinoma reported in the(More)
In this paper, we propose an efficient method for implementing Dijkstra's algorithm for the Single Source Shortest Path Problem (SSSPP) in a graph with positively lengthed edges, and where there are few distinct lengths. The SSSPP is one of the most widely studied problems in theoretical computer science and operations research. On a graph with n vertices,(More)
1. Explain with an example (in C), the differences between parameter passing by value and parameter passing by reference. 2. Briefly explain the themes of imperative programming, functional programming and logic programming. 3. What are the different types of errors that can occur in a program? Give one example of each. 4. Let Σ = {0, 1} denote an alphabet(More)
We consider the satisfiability problem for Boolean combinations of unit two variable per inequality (UTVPI) constraints. A UTVPI constraint is linear constraint containing at most two variables with non-zero coefficients, where furthermore those coefficients must be either −1 or 1. We prove that if a satisfying solution exists, then there is a solution with(More)
