A class of exponential,realistic modified gravities is introduced and investigated with care. Special focus is made on step-class models, most promising from the phenomenological viewpoint and which provide a natural way to classify all viable modified gravities. One- and two-step models are explicitly considered, but the analysis is extensible to N-step models. Both inflation in the early universe and the onset of recent accelerated expansion arise in these models in a natural,unified way. Moreover,it is demonstrated that models in this category easily pass all local tests,including stability of spherical body solution, nonviolation of Newton\u0027s law, and generation of a very heavy positive mass for the additional scalar degree of freedom.", "subitem_description_type": "Abstract"}]}, "item_10_identifier_60": {"attribute_name": "URI", "attribute_value_mlt": [{"subitem_identifier_type": "HDL", "subitem_identifier_uri": "http://hdl.handle.net/2237/11275"}]}, "item_10_publisher_32": {"attribute_name": "\u51fa\u7248\u8005", "attribute_value_mlt": [{"subitem_publisher": "American Physical Society"}]}, "item_10_relation_11": {"attribute_name": "DOI", "attribute_value_mlt": [{"subitem_relation_type_id": {"subitem_relation_type_id_text": "http://dx.doi.org/10.1103/PhysRevD.77.046009", "subitem_relation_type_select": "DOI"}}]}, "item_10_rights_12": {"attribute_name": "\u6a29\u5229", "attribute_value_mlt": [{"subitem_rights": "American Physical Society, All rights reserved."}]}, "item_10_select_15": {"attribute_name": "\u8457\u8005\u7248\u30d5\u30e9\u30b0", "attribute_value_mlt": [{"subitem_select_item": "publisher"}]}, "item_10_source_id_7": {"attribute_name": "ISSN", "attribute_value_mlt": [{"subitem_source_identifier": "1550-7998", "subitem_source_identifier_type": "ISSN"}]}, "item_10_text_14": {"attribute_name": "\u30d5\u30a9\u30fc\u30de\u30c3\u30c8", "attribute_value_mlt": [{"subitem_text_value": "application/pdf"}]}, "item_creator": {"attribute_name": "\u8457\u8005", "attribute_type": "creator", "attribute_value_mlt": [{"creatorNames": [{"creatorName": "Cognola, G."}], "nameIdentifiers": [{"nameIdentifier": "27033", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Elizalde, E."}], "nameIdentifiers": [{"nameIdentifier": "27034", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Nojiri, S."}], "nameIdentifiers": [{"nameIdentifier": "27035", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Odintsov, S.
