Interspecific competition determines the invasive capability of alien plants. Phytolacca americana, one most destructive plants in China, was first discovered and recorded China 1935. Since its arrival, rapid expansion species has driven out a native congener, acinosa. In this study, we assessed competitive interaction P. americana acinosa pot experiment at Yunnan University. Our results indica...

Sequence-specific recognition of DNA can be achieved by triple helix-forming oligonucleotides that bind to the major groove of double-helical DNA. These oligonucleotides have been used as sequence-specific DNA ligands for various purposes, including sequence-specific gene regulation in the so-called 'antigene strategy'. In particular, (G,A)-containing oligonucleotides can form stable triple hel...

In this article, we study population dynamics of a general two-species discrete-time competition model where each species suffers from strong Allee effects and scramble intra-competition. We focus on how combination of intra-specific and inter-specific competition affect the extinction and coexistence of these two competing species that are subject to strong Allee effects. We derive sufficient ...

Hardware implementation quality will be considered as an important factor for evaluating the NIST SHA-3 competition candidates in the second round. The most traditional and popular hardware im­ plementation method is designing ASICs with standard cells. However, to benchmark 14 second round SHA-3 ASIC designs based on a fair and comprehensive methodology can be very challenging because of the u...

Both theoretical predictions and experimental findings suggest that T cell populations can compete with each other. There is some debate on whether T cells compete for aspecific stimuli, such as access to the surface on antigen-presenting cells (APCs) or for specific stimuli, such as their cognate epitope ligand. We have developed an individual-based computer simulation model to study T cell co...

Individuals of different sex, size or developmental stage can compete differently and hence contribute distinctively to population dynamics. In species with complex life cycles such as insects, competitive ability is often positively correlated with larval developmental stage. Yet, little is known on how the development and survival of early-instars is influenced by interference from late-insta...

The study of the ‘dynamic’ aspects of language – variation and change – and the development of grammatical theory are often pursued independently of one another. Concentrating on morphosyntax, this article explores connections between these domains that are centered on the notion of ‘competition’. When the relationship between competition for grammaticality and competition for use is articulate...

How do speakers choose between structural options for expressing a given meaning? Overall preference for some structures over others as well as prior statistical association between specific verbs and sentence structures ("verb bias") are known to broadly influence language use. However, the effects of prior statistical experience on the planning and execution of utterances and the mechanisms t...

Hierarchical structured models for scramble and contest intraspecific competition are derived. The dynamical consequences of the two modes of competition are studied under the assumption that both populations divide up the same amount of a limiting resource at equal population levels. A comparison of equilibrium levels and their resiliences is made in order to determine which mode of competitio...

This paper describes a method of obtaining MOLS of order v = 2np for p a prime power. In particular, it gives 5,7 and 9 MOLS of orders 48,40 and 80 respectively. If x = Min(2p-1 ,2n-1 ,4n-2) , it is conjectured that x MOLS of order v are always-obtainable by this method. Australasian Journ::ll of ~ohmin::ltnrirc: 101 1QQLl \ n .... 17f.;;_1Qg::
