Let R(Ka,b, Kc,d) be the minimum number n so that any n-vertex simple undirected graph G contains a Ka,b or its complement G′ contains a Kc,d. We demonstrate constructions showing that R(K2,b, K2,d) > b + d + 1 for d ≥ b ≥ 2. We establish lower bounds for R(Ka,b, Ka,b) and R(Ka,b, Kc,d) using probabilistic methods. We define R′(a, b, c) to be the minimum number n such that any n-vertex 3-unifor...

determination of the total body absorbed dose consists of two parts: beta radiation absorbed dose and gamma radiation absorbed dose. the first part is generally determined by clinical data, while the second part has a parameter called absorbed ratio and is determined by computational methods. the monte-carlo computational methods have been shown to be the most suitable in determination of the a...
