The seesaw mechanism is introduced and some of its different realizations and applications are discussed. It is pointed out how they can be used to understand the bi-large mixing patterns among neutrinos in combination with the assumptions about high scale physics such as grand unification or quasidegeneracy of neutrino masses.

We examine the structure of the quaternion group Q8 and its possible application to the physics of flavor. We find that a Q8 family symmetry is suitable to explain the difference between quark and lepton mixing patterns. Distinctive phenomenological predictions are derived for the neutrino sector and the electroweak Higgs sector. We also show how the Q8 symmetry suppresses the effective operato...

In this paper we investigate the communication behavior of common mathematical software. This observed mechanisms are classi ed and described as interaction patterns. Beside the control ow aspect of these interaction patterns, we also investigate the message-related aspect and provide a general architecture as base for further research. Identifying the interaction patterns facilitates the devel...

Background: Identification of food patterns is of crucial important. As far as we know, no study has been yet carried out in the west of Iran. The aim of this study was to determine staple food patterns among adult persons in Khorramabad city. Materials and Methods: In this cross-sectional study food intake of 973 people (736 women) were gathered by Food Frequency Questionnaire (FFQ 208 food i...

Defining phenotypes according to molecular features would promote the knowledge of functional traits like behaviour in both human and animal research. Beside physiological states or environmental factors, an innate predisposition of individual coping strategies was discussed, including the proactive and reactive pattern. According to backtest reactivity, animals assigned as high-resisting (proa...

Patient treatment processes require the cooperation of different organizational units and medical disciplines. In such an environment an optimal process support becomes crucial. Though healthcare processes frequently change, and therefore the separation of the flow logic from the application code seems to be promising, workflow management technology has not yet been broadly used in healthcare e...

With the increase in multi-cultural families, Korea is seeing a rapid increase in immigrated housewives, who are closely related to food culture. However, studies for the diet of multi-cultural families, which is most closely related to our lives have not been sufficiently researched. With this background, this study conducted research for immigrated women nationwide about food cultures to prov...

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 ...
