We computationally study the transport of active, self-propelled particles suspended in a two-dimensional chaotic flow. The pointlike, spherical particles have their own intrinsic swimming velocity, which modifies the dynamical system so that the particles can break the transport barriers present in the carrier flow. Surprisingly, we find that swimming does not necessarily lead to enhanced part...

Soybean (Glycine max L.) is one of the most valuable oilseed crops in world. It not only an oil seed crop and feed for livestock, but also mineral vitamins sources human diet. The soybean yield affected by various biotic abiotic stress factors all growing seasons. Diseases are significant that reduce growth yield. Fungi important pathogens affecting quality attacking plants during period after ...

For years, my group has used microorganisms as models to address fundamental hypotheses about the mechanisms and dynamics of genetic, ecological, and evolutionary processes [1-4]. In these fields, there are many interacting entities and hence a tremendous number of potential interactions. Identifying general rules, if any, that govern the form of these interactions might be important for develo...

Urban structures in the form of pontoons and pilings represent major coastal habitats for marine organisms and understanding the factors causing abundances of organisms to differ between these and natural habitat has been neglected in the study of coastal ecology. It has been proposed that composition of substrata explain differences previously described between subtidal assemblages of epibiota...

Functional connectivity, the degree to which the landscape facilitates or impedes movement, depends on how animals perceive costs and benefits associated with habitat features and integrate them into a movement path. There have been few studies on functional connectivity in marine organisms, despite its importance for the effectiveness of Marine Protected Areas. In this study, we asked how open...

Over the years, genetically modified organism (GMO) development and regulation in China have regularly attracted international attention. In the early 1990s, China became the first country to commercialize a genetically modified (GM) crop with planting of a virus-resistant transgenic tobacco variety on a relatively large scale, while other parts of the world were debating about the risks of GMO...
