The objective of an Automated Highway System (AHS) is to increase the safety and through-put of the existing highway infrastructure by introducing traac automation. AHS is an example of a large scale, multi-agent, complex dynamical system and is ideally suited for a hierarchical hybrid controller. We discuss the design of safe and eecient hybrid controllers for regulation of vehicles on an AHS....

We observe two problems in the current scheduling schemes for in-network sensor query processing: (1) A query execution plan never changes after it is injected into the network and (2) the data communication schedule rarely considers the query workload. Both problems severely hurt the performance, because the runtime dynamics, such as the wireless connectivity and the data flows, change frequen...

he Armenian hamster (AH), Cricetulus migratorius, was first used in biomedical research by Yerganian and Papoyan (1). This rodent has a low diploid number of 22 chromosomes, like the Chinese hamster, and was analyzed using routine and differential staining (1,2). The AHs are successfully used in mutagenesis studies such as detection of reciprocal translocations in the germ cells (3), chromosoma...

OBJECTIVE To evaluate cefuroxime and metronidazole antibiotic prophylaxis. DESIGN Observational nonrandomised 1-year prospective cohort study. SETTING Fifty-three hospitals in Finland. POPULATION A total of 5279 women undergoing hysterectomy for benign indications, with cefuroxime given to 4301 and metronidazole given to 2855. Excluding other antibiotics, cefuroxime alone was given to 201...

Adaptive Hypermedia Systems (AHS) have long been concentrating on adaptive guidance of links between domain concepts with lots of custom developments and ad-hoc implementations. Here we consider a formalization approach to AHS composition and design by defining building blocks’ interfaces and presenting corresponding dependencies by means of the GAF framework. This helps to identify system desi...

Aquatic humic substances (AHSs) are major constituents of dissolved organic matter (DOM) in freshwater, where they perform a number of important ecological and geochemical functions, yet no method exists for quantifying all AHSs. We have developed a method for the quantitative analysis of AHSs based on their carbon concentration. Our approach includes: (1) the development of techniques for cl...

We reviewed epidemiologic evidence related to occupational pesticide exposures and cancer incidence in the Agricultural Health Study (AHS) cohort. Studies were identified from the AHS publication list available on a Medline/PubMed database search in March 2009. Findings related to lifetime-days and/or intensity-weighted lifetime-days of pesticide use are the primary focus of this review, becaus...

Predicted global climate change threatens the distributional ranges of species worldwide. We identified genes expressed in the intertidal seagrass Zostera noltii during recovery from a simulated low tide heat-shock exposure. Five Expressed Sequence Tag (EST) libraries were compared, corresponding to four recovery times following sub-lethal temperature stress, and a non-stressed control. We sequ...
