This study was designed to evaluate efficacy of a natural eye drop made of Plantago ovata mucilage versus placebo to improve dry eye symptoms. In a Randomized, double-masked, placebo-controlled clinical trial, sixty dry eye patients with ocular symptom and total OSDI score≥12 were randomly assigned to receive either a natural ophthalmic drop, made of Plantago ovata mucilage or placebo 4 times a...

Today, we will use an algebraic approach to solve the matching problem. Our goal is to derive an algebraic test for deciding if a graph G = (V, E) has a perfect matching. We may assume that the number of vertices is even since this is a necessary condition for having a perfect matching. First, we will define a few basic needed notations.
