Abstract Effective theory framework based on symmetry has recently gained widespread interest in the field of cosmology. In this paper, we apply same idea genesis primordial magnetic and its evolution throughout cosmological universe. Given broken time-diffeomorphism by background, considered most general Lagrangian electromagnetic metric fluctuation up to second order, which naturally breaks c...

Composite Higgs models based on the chiral symmetries of " theory space " can produce Higgs bosons with masses of order 100 GeV from underlying strong dynamics at scales up to 10 TeV without fine tuning. This talk argues that flavor-violating interactions generically arising from underlying flavor dynamics constrain the Higgs compositeness scale to be > ∼75 GeV, implying that significant fine-t...

the sudden transfer of guardianship, from husband to wife, causing a string of insecurity and additional duties for women. the phenomenon of woman-headed households is increasing for different reasons in the world. studies indicate that, householder women are facing social and economic challenges and constraints. the aim of this study is pathology of social interactions women-headed households ...

careful analysis of the ferdows persian accent showed that the back vowel /a/ changes to front vowel [a] in the first syllable of bi-syllabic words and in the second syllable of tri-syllabic words. however, this does not occur in the last syllable. it was also found that different processes occur before nasals; /a/ changes to [o] before /m/. but before /n/, it changes to [a] in the penult of ...

credit allocation through the usage of portfolio optimization mainly seeks tomaximize return and minimize the risk of the portfolio; but there are other importantissues including sustainable development which is important for government/publicsectors. this paper presents a novel credit allocation approach based on portfoliooptimization and investigates the effects of selected indicators of sust...

Purpose – The purpose of this paper is to suggest that the theory of constraints (TOC) can serve as a general theory in operations management. The paper first investigate linkages between TOC and the core concepts/components of operations management (OM) and show how OM concepts can be integrated with TOC using examples from the published TOC literature. A second important purpose is to show th...
