Understanding the disparate mixing patterns between quarks and leptons is one of the major challenges in particle theory today. I discuss some of the ways to understand this difference within the seesaw framework using new symmetries of quarks and leptons. After a brief introduction to the various types of seesaw formulae, proposals for understanding large solar and atmospheric mixings for the ...

in this paper, the temperature and annual precipitation data has been applied in 44 years for the synoptical stations northwest zone of iran. among the stations, eight of them, which have the perfect data and coverage, has been considered to analysis applied. in this study transfer function models have been used to analysis time series. in this method, firstly, the stations have been modeled th...

The new extremely large telescope projects need accurate evaluation of the candidate sites. In this paper we present the astroclimatological comparison between the Paranal Observatory, located on the coast of the Atacama Desert (Chile), and the Observatorio del Roque de Los Muchachos (ORM), located in La Palma (Canary Islands). We apply a statistical analysis using long term databases from Para...

Results of continuous nitrogen oxide (NO), nitrogen dioxide (NO2), peroxyacetyl nitrate (PAN) and total reactive nitrogen (NOy) measurements along with seasonal field campaigns of nitric acid (HNO3) and particulate nitrate (NO−3 ) measurements are presented for a two-year period at the high-alpine research station Jungfraujoch (JFJ), 3580 m asl. The NOy mixing ratio and partitioning is shown to...

This paper describes an object oriented editor for designing and running graphical user interfaces for control screens of the Distributed Object Oriented Control System (DOOCS). The whole DOOCS system [1] is based on the object-oriented methodology, i.e. devices are handled as objects, data objects are transferred between client and server programs and the data is visualized by display objects....

OBJECTIVES To review recent research efforts in the field of ubiquitous computing in health care. To identify current research trends and further challenges for medical informatics. METHODS Analysis of the contents of the Yearbook on Medical Informatics 2005 of the International Medical Informatics Association (IMIA). RESULTS The Yearbook of Medical Informatics 2005 includes 34 original pap...

In recent years, three different enzymatic pathways and a few non-enzymatic reactions have been proposed for the generation of NO in plant roots. Two of the enzymatic pathways are located in the cytosol of the plant cells, whereas the third is exclusively located in the root plasma membrane facing the apoplast from where it seems to interact with nitrate metabolism by producing signals. A respo...

High-Throughput Screening (HTS) data in its entirety is valuable raw material for the drug-discovery process. It provides the most complete information about the biological activity of a company's compounds. However, its quantity, complexity and heterogeneity require novel, sophisticated approaches in data analysis. At GeneData, we are developing methods for large-scale, synoptical mining of sc...
