We present a polynomial-time approximation algorithm for legally coloring as many edges of a given simple graph as possible using two colors. It achieves an approximation ratio of 468 575 . This improves on the previous best (trivial) ratio of 45 .
BACKGROUND Zanthoxylum armatum DC has been an important traditional plant known for its medicinal properties. It is well known for its antimicrobial, larvicidal and cytotoxic activities. METHODS The potential anticancer effects of the methanol extract and the crude saponins from fruit, bark and leaves of Z. armatum on breast (MDA-MB-468 and MCF-7) and colorectal (Caco-2) cancer cell lines usi...
این پژوهش به شرح واژه های مندرج در آیات اوّل تا چهلمِ سوره مبارک نساء بر اساس تفسیر مجمع البیان طبرسی اختصاص دارد و در پنج فصل سامان یافته است. فصل اوّل به تعریف مفردات قرآن پرداخته و سوره نساء را به صورت اجمالی معرّفی می کند. آن گاه پیشینه ای از علم مفردات قرآن و رویکردهای تفسیری در این زمینه ارایه شده و پس از آن در فصول دوم تا پنجم واژه گان مورد نظر از آیات اوّل تا چهلم بررسی لغوی، اصطلاحی و تفسیر...
BACKGROUND Overexpression of syndecan-1 (CD138) in breast carcinoma correlates with a poor prognosis and an aggressive phenotype. The objective of this study was to evaluate the potential of targeting CD138 by immuno-PET imaging and radioimmunotherapy (RIT) using the antihuman syndecan-1 B-B4 mAb radiolabeled with either 124I or 131I in nude mice engrafted with the triple-negative MDA-MB-468 br...
