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...

Scientific Production of Medical Universities in the West of Iran: a Scientometric Analysis

INTRODUCTION This study aimed to compare scientific production by providing quantitative evaluation of science output in five Western Iranian Medical Universities including Hamedan, Ilam, Kermanshah, Kurdistan and Lorestan University of Medical Sciences using scientometrics indicators based on data indexed in Scopus for period between the years 2010 to 2014. METHODS In this scientometric stud...

A practical algorithm for [r, s, t]-coloring of graph

Coloring graphs is one of important and frequently used topics in diverse sciences. In the majority of the articles, it is intended to find a proper bound for vertex coloring, edge coloring or total coloring in the graph. Although it is important to find a proper algorithm for graph coloring, it is hard and time-consuming too. In this paper, a new algorithm for vertex coloring, edge coloring an...

NITROIMIDAZOLES VII [I]. SYNTHESES, ANTIBACTERIAL AND ANTIFUNGAL ACT I V I T I E S OF 4 - S U B S T I T U T E D - 2 - TWIAZOLYLHYDRAZONES

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 ...
