Afghanistan is responsible for the majority of the world’s supply of poppy crops, which are often used to produce illegal narcotics like heroin. This paper presents an agent-based model that simulates policy scenarios to characterize how the production of poppy can be dampened and replaced with licit crops over time. The model is initialized with spatial data, including transportation network a...

Hypoxysordarin (1), a new sordarin derivative, was isolated from the fermentation broth of the facultative marine Hypoxylon croceum together with a new gamma-lactone, hypoxylactone (2) and sordarin (3). The structures were determined by spectroscopic methods. Sordarin (3) has previously been isolated from the terrestrial Sordaria araneosa (Sordariaceae). Like the parent compound hypoxysordarin ...

The self-incompatibility response involves S allele-specific recognition between stigmatic S proteins and incompatible pollen. This response results in pollen inhibition. Defining the amino acid residues within the stigmatic S proteins that participate in S allele-specific inhibition of incompatible pollen is essential for the elucidation of the molecular basis of the self-incompatibility respo...

in this paper, we use parametric form of fuzzy number and we converta fuzzy linear system to two linear system in crisp case. conditions for the existence of a minimal solution to $mtimes n$ fuzzy linear equation systems are derived and a numerical procedure for calculating the minimal solution is designed. numerical examples are presented to illustrate the proposed method.
