The platformised news environment affects audiences, challenges the media’s role, and transforms media ecosystem. Digital platform companies influence opinion formation hence wield “opinion power,” a normatively constitutionally rooted notion that captures core of power in democracy substantiates why must be distributed. Media concentration law is traditional tool to prevent predominant from em...

BACKGROUND: Platform switching for maintaining peri-implant bone levels has gained popularity among implant manufacturers over the last few years. However, the assumption that the inward shifting of the implant-abutment junction may preserve crestal bone was primarily based on serendipitous finding rather than scientific evidence. The objectives of the present study were to systematically revie...

Biological studies into antidepressant drug action and into the aetiology of depression were highly active areas of research in the 1960s and 1970s but, arguably, have now lost some of their impetus and direction. Many investigations seem to have come to a natural end and there is a need for the subject to make a quantum leap to promote its development. It is recognized however, that advances h...

A region of the brain called the putamen has a central role in procedural memory consolidation during sleep.

Switching between mental sets has been extensively investigated in both experimental and individual differences research using a wide range of task-switch paradigms. However, it is yet unclear whether these different tasks measure a unitary shifting ability or reflect different facets thereof. In this study, 20 task pairs were administered to 119 young adults to assess 5 proposed components of ...

the sirri jacket offshore platform was designed and installed in persian gulf of iran in 1975 and has been in service since that time. the importance of offshore structure's stability and the failure of this kind of structure during an earthquake in different active zones revealed that earthquake loading has to be considered. in this paper, magnetorheological (mr) fluid dampers have been propos...

low calorie diets are always difficult for obese subjects to follow and lead to metabolic and behavioral adaptation. therefore, we evaluated the effect of caffeine treatment with calorie shifting diet (csd) on weight loss. female subjects (n=98; bmi≥25) completed 4-weeks control diet, 6-weeks csd (3 repeated phases; each 2-weeks) and 4-weeks follow-up diet, with or without caffeine treatment (5...

Gil Kalai introduced the shifting-theoretic upper bound relation to characterize the f -vectors of Gorenstein* complexes (or homology spheres) by using algebraic shifting. In the present paper, we study the shifting-theoretic upper bound relation. First, we will study the relation between exterior algebraic shifting and combinatorial shifting. Second, by using the relation above, we will prove ...
