A (convex) polytope is the convex hull of finitely many points in Rd. Alternatively, a polytope can be defined as the bounded intersection of finitely many halfspaces, that is, a polytope is the (bounded) solution set of a system of linear equations and inequalities. (This latter fact is the main non-geometric reason why people are interested in polytopes—linear systems are everywhere.) The mai...

and steroids. As part of our search for bioactive substances from marine organisms, the Formosan soft coral Nephthea elongata KÜKENTHAL (Nephtheidae) was studied because the CH2Cl2 extracts showed significant cytotoxicity to P-388 (mouse lymphocytic leukemia) cell culture as determined by standard procedures. Bioassay-guided fractionation resulted in the isolation and chraracterization of seven...

Since publication of IEEE-1149.1-1990/ANSI 1, 2, 3, extensions and requests for clarifications have been adopted by the IEEE 1149.1 Working Group. The original standard established a common, industry-wide methodology for the application of scan test access. The rapid acceptance of this standard and use by semiconductor designers, test engineers and systems developers has resulted in questions n...

A novel integrated semiconductor photonic switch, based on carrier-induced refractive index changes, has been designed and fabricated for use at near infrared wavelengths (890-920 nm, 750-780 nm 745-775 nm). These switches are intended in quantum sensors which rely the spectroscopy of caesium, rubidium or potassium atoms respectively. The beam-steering properties 890-920 device presented its ex...

{2-[1-(3-Methoxycarbonylmethyl-1H-indol-2-yl)-1-methyl-ethyl]-1H-indol-3-yl}-acetic acid methyl ester (MIAM) was provided as a DNA-intercalator. For the comprehensive evaluation of this new intercalator, an assay system consisting of cell, S180 mouse, healthy mouse, spectrum, non-spectrum, and gel electrophoresis models was constructed. On the cell (S180, K562, MCF-7, HeLa and HepG2) models, MI...

Aim: To compare the antimicrobial efficacy of five Medicinal plant extracts against two strains of Streptococcus mutans causing dental caries using Agar well diffusion method. Materials and methods: Five plant extracts were prepared by soxhlet extraction method using organic solvent. These extracts were tested against Streptococcus mutans MTCC 497& MTCC 890 causing dental caries by Agar well di...
