The origin and dynamic evolution of chemical information transfer.
Although chemical communication is the most widespread form of communication, its evolution and diversity are not well understood. By integrating studies of a wide range of terrestrial plants and animals, we show that many chemicals are emitted, which can unintentionally provide information (cues) and, therefore, act as direct precursors for the evolution of intentional communication (signals)....
متن کاملChemical information transfer between plants: back to the future
Chemical information conveyance between organisms has been well established for a wide range of organisms including protozoa, invertebrates, vertebrates and plant-parasitic plants. During the past 20 years, various studies have addressed whether chemical information conveyance also occurs between damaged and undamaged plants and many interesting pieces of evidence have been presented. To date, ...
متن کاملTransfer of Learned Heuristics among Planners∗
This paper presents a study on the transfer of learned control knowledge between two different planning techniques. We automatically learn heuristics (usually, in planning, heuristics are also named control knowledge) from one planner search process and apply them to a different planner. The goal is to improve this second planner efficiency solving new problems, i.e. to reduce computer resource...
متن کاملLessons learned? Chemical plant safety since Bhopal.
Comprehensive mapping of transcription factor binding sites is essential in postgenomic biology. For this, we propose a mining approach combining noisy data from ChIP (chromatin immunoprecipitation)-chip experiments with known binding site patterns. Our method (BoCaTFBS) uses boosted cascades of classifiers for optimum efficiency, in which components are alternating decision trees; it exploits ...
متن کاملLessons learned from gene transfer approaches
Recent technological advances allow the transfer of genes to the synovial lining of joints. As well as opening novel opportunities for therapy, these techniques provide valuable new tools for the study of synovitis and other aspects of the biology of joints in health and disease. This article reviews briefly the results of experiments in which selected genes have been transferred to the knee jo...
