a novel acrylic acid-functionalized fe3o4 magnetic nanoparticle with a core-shell structure was developed for utilization as a heterogeneous organosuperacid in chemical transformations. the structural, surface, and magnetic characteristics of the nanosized catalyst were investigated by various techniques such as transmission electron microscopy (tem), thermogravimetric analysis (tga), and ft-ir...

1. Improving the mechanistic basis of biodiversity–ecosystem function relationships requires a better understanding of how functional traits drive the dynamics of populations. For example, environmental disturbances or grazing may increase synchronization of functionally similar species, whereas functionally different species may show independent dynamics, because of different responses to the ...

introduction: we did this study because there were a few studies about aorto-branch junction. methods: four light microscope and electron microscope study, the abdominal aorta, renal artery, and the adjoining right and left renal arteries were dissected out from 4 neonate dogs. results: based on the results, there is only one cell type in the tunica intima of endothelium in both arteries. in ab...

Introduction The amount of information available to users, especially in the web, is growing exponentially month by month. To nd useful information in the web, users normally have to rely on some sort of keyword matching searches, and/or navigate their way through the list of pointers to objects in diierent data repositories. This is not enough to satisfy the needs of the ever more sophisticate...

We investigate the alignment of international attention of news media organizations within 193 countries with the expressed international interests of the public within those same countries from March 7, 2016 to April 14, 2017. We collect fourteen months of longitudinal data of online news from Unfiltered News and web search volume data from Google Trends and build a multiplex network of media ...

ELISPOT assays are routinely used to measure immune responses of T cells in fresh and frozen splenocytes preparations; however, standardized methods for murine ELISPOT are not widely available. Freezing cells can significantly impact the function of T cells. The aim of this study was to optimize cryopreservation protocols to retain antigen-specific T cell function at similar levels as freshly i...

Entity matching that finds records referring to the same entity is an important operation in data cleaning and integration. Existing studies usually use a given similarity function to quantify the similarity of records, and focus on devising index structures and algorithms for efficient entity matching. However it is a big challenge to define “how similar is similar” for real applications, sinc...

MCCUNE, B., and T. F. H. ALLEN. 1985. Will similar forests develop on similar sites? Can. J. Bot. 63: 367-376. Abies grandis, Taxus brevifolia, Thuja plicata, or any combination of these may dominate old-growth mesic forests of the Bitterroot Canyons, western Montana. Similar sites need not develop similar, relatively stable forests. This is shown by (i) anomalous distributional patterns of tre...

Social media have transformed datadriven research in political science, the social sciences, health, and medicine. Since health research often touches on sensitive topics that relate to ethics of treatment and patient privacy, similar ethical considerations should be acknowledged when using social media data in health research. While much has been said regarding the ethical considerations of so...
