Logical s-t Min-Cut Problem: An Extension to the Classic s-t Min-Cut Problem
Let $G$ be a weighted digraph, $s$ and $t$ be two vertices of $G$, and $t$ is reachable from $s$. The logical $s$-$t$ min-cut (LSTMC) problem states how $t$ can be made unreachable from $s$ by removal of some edges of $G$ where (a) the sum of weights of the removed edges is minimum and (b) all outgoing edges of any vertex of $G$ cannot be removed together. If we ignore the second constraint, ca...
متن کاملHyers-Ulam Stability of the Delay Equation y'(t)=y(t-)
and Applied Analysis 3 we describe a behavior of solutions of the following problem the delay differential inequality with an initial condition ε1 ≤ y′ t − λy t − τ ≤ ε2, t ≥ 0, 1.5 ξ1 t ≤ y t − y 0 ≤ ξ2 t , −τ ≤ t ≤ 0, 1.6 and compare them with solutions of the delay equation 1.4 that are constant on the interval −τ, 0 and therefore have quite simple forms . Functions satisfying those two ineq...

Reaction of readily available 2-formyl -1-methyl-5-nitroimidazole (1) with 4-substituted-2-hydrazinothiazoles (2) afforded 2-formyl-l-methyl-5- nitroimidazole 4-substituted -2- thiazolylhydrazones (3). Reaction of thiochromitn-4-one (4) with thiosemicarbazide gave thiochroman-4- one thiosemicarbazone (5). Reaction of compound 5 with clc- haloaldehyde or ketones y ielded thiochroman--#-one ...
متن کاملThe in D U C T Io N of Secondary Cytolytic T L Y M
As a result of genetic and immunological evidence, it is now well established that the induction of murine cytolytic T cells (CTL) depends upon the recognition of antigens which are gene products of the major histocompatibility complex (MHC) of the stimulating cell. A more detailed understanding of the molecular events involved in this specific recognition would be greatly aided by the ability ...
