An efficient numerical method for computing permanental polynomials of graphs is proposed. It adapts multi-entry expansion of FFT, and is parallel in nature. It is applied to fullerene-type graphs, and works for C56, while the largest fullerene computed before is C40. Extensive numerical computations show that the algorithm is fast and stable. © 2006 Elsevier B.V. All rights reserved. PACS: 02....

To promote understanding of how organisms are related via carotenoids, either evolutionarily or symbiotically, or in food chains through natural histories, we built the Carotenoids Database. This provides chemical information on 1117 natural carotenoids with 683 source organisms. For extracting organisms closely related through the biosynthesis of carotenoids, we offer a new similarity search s...

In this study, we investigated how increasing temperature affects tomato fruit physicochemical traits and looked for genetic variability to help maintain quality in the context of climate change. High (HT: +3 °C) was applied at four developmental stages, from anthesis 15, 30 or 45 days after until ripening three genotypes, a commercial cultivar (Money Maker, “MM”) two genotypes likely more tole...

Many municipalities undertake actions individually and/or collectively, in cooperation with central administrations, regional authorities, the private sector, and other (both nationally internationally). This paper aims to examine how they use transnational municipal networks (TMNs) as a tool for that supports marine governance context of climate change adaptation mitigation. The analysis is ca...

In hydrogen energy systems, the polymer electrolyte fuel cell (PEFC) is an important component. The purpose of this study to clarify effect separator thickness (s.t.) in PEFC on distributions mass such as H2, O2, H2O and current density when operated at 363 K 373 K. relative humidity (RH) supply gases also impacts operation. numerical simulation (using a 3D model) with COMSOL Multiphysics has b...

Many biological and geochemical questions remain concerning the structures, functions, and properties of naturally occurring high-molecular-weight (C40+) alkanes with various mid-chain alkylation patterns. Above C40, these alkanes are exceedingly difficult to separate and purify, and syntheses can be blocked by the low solubility of intermediates. To overcome these problems, a facile three-step...
