Abstract In recent years, research on Physarum polycephalum has become more popular after Nakagaki (AIR 407: 6803-470, 2000) performed their famous experiment showing that was able to find the shortest route through a maze. Subsequent researches have confirmed ability of Physarum-inspired algorithms solve wide range real-world applications. contrast previous reviews either focus biological aspe...

Understanding the causes of substitution rate variation is an important goal in the study of molecular evolution. It has been proposed that sperm competition intensity may affect genome-wide rates of substitution as a by-product of selection on sperm numbers. Here, I test this hypothesis by applying recently developed Bayesian methods to a data set consisting of approximately 35 kb of sequence ...

Remotely sensed land surface temperature and fractional vegetation coverage (LST/FVC) space has been widely used in modeling and partitioning land surface evaporative fraction (EF) which is important in managing water resources. However, most of such models are based on conventional trapezoid and simply determine the wet edge as air temperature (Ta) or the lowest LST value in an image. We devel...

Cooper et al. (this issue) develop an interactive activation model of spatial and imitative compatibilities that simulates the key results from Catmur and Heyes (2011) and thus conclude that both compatibilities are mediated by the same processes since their single model can predict all the results. Although the model is impressive, the conclusions are premature because they are based on an inc...

In order to maintain universal access to medically effective care for all, costs must be contained at both the system-wide and micro levels. The managed competition model offers a framework within which increased efficiency could be pursued without sacrificing the goal of universal access and without impairing health outcomes and social cohesion. It would do this by removing structural impedime...

This article describes the development and history of a sustainability photography competition. From its simple beginnings as an environmental officer‘s idea, an environmental sustainability photography competition began in just one university. Now hosted by Australasian Campuses Towards Sustainability (ACTS), finalist entries are viewed on a public website gaining international attention. A pu...

This paper discusses the incentive to bundle when consumer valuations are nonadditive and/or when products are supplied by separate sellers. Whether integrated or separate, firms have an incentive to introduce a bundle discount when demand for the bundle is elastic relative to demand for stand-alone products. A simple formula is derived for when an integrated firm supplying substitute products ...

We study stochastic dynamics of two competing complexation reactions (i) A + B↔AB and (ii) A + C↔AC. Such reactions are common in biology where different reactants compete for common resources--examples range from binding enzyme kinetics to gene expression. On the other hand, stochasticity is inherent in biological systems due to small copy numbers. We investigate the complex interplay between ...
