In tropical forests, trees compete not only with other trees, but also with lianas, which may limit tree growth and regeneration. Liana effects may depend on the availability of aboveand below-ground resources and differ between tree species. We conducted a shade house experiment to test the effect of light (4% and 35% full sun, using neutral-density screen) on the competitive interactions betw...

Auburn University has a competition Autonomous Lawnmower team and competes every year at ION’s competition [1] in Dayton, OH. This paper describes the how the team has approached coverage path planning for the lawnmower given the competition constraints. The competition setting dictates a closed polygon filed, which can be concave, and it will contain several static and dynamic obstacles. The p...

As a psycholinguistic model of language comprehension and acquisition, the Unified Competition Model was developed to account for both first and second language comprehension and acquisition. The Unified Competition Model posits that languages have a number of cues which receivers of language use in order to comprehend the input they receive. This model is based on the idea that mental processi...

Males and females frequently differ in their rates of ageing, but the origins of these differences are poorly understood. Sex differences in senescence have been hypothesized to arise, because investment in intra-sexual reproductive competition entails costs to somatic maintenance, leaving the sex that experiences stronger reproductive competition showing higher rates of senescence. However, ev...

In Europe, the past twenty years saw a process of liberalisation, deregulation and unprecedented financial sector reform whose main aims were to increase competition and remove all remaining barriers to the integration of EU banking sectors. However, the recent acceleration in the consolidation process has raised concerns about the potential implications for public policies deriving from increa...

In this article, we study the population dynamics of a two-species discrete-time competitionmodelwhere each species suffers from either predator saturation induced Allee effects and/or mate limitation induced Allee effects. We focus on the following two possible outcomes of the competition: 1. one species goes to extinction; 2. the system is permanent. Our results indicate that, even if one spe...

It is generally considered that more competition might help curb corruption, as rents, which motivate corrupt agreements, are decreasing in the degree of competition. This paper proposes a framework to analyze the relationship between corruption and competition. It studies the optimal incentive scheme for potentially corrupt officials in charge of inspecting firms that compete in the product ma...

Intraand inter-specific competition between seedlings of Acacia etbaica Schweinf. and the grass Hyparrenia hirta (L.) Stapf. was studied to evaluate the influence of the perennial grass on the establishment of the tree seedlings. The experiment was conducted using a replacement series in which plants were grown in a greenhouse at an overall density of six individuals per pot, providing combinat...
