These probabilities can be visualized as matrices called contact maps. In this paper, we introduce a multifractal analysis of chromosomal contact maps. Our analysis reveals that Hi-C maps are bifractal, i.e., complex geometrical objects characterized by two distinct fractal dimensions. To rationalize this observation, we introduce a model that describes chromosomes as a hierarchical set of nested domains and we solve it exactly. The predicted multifractal spectrum is in excellent quantitative agreement with experimental data. Moreover, we show that our theory yields a more robust estimation of the scaling exponent of the contact probability than existing methods. By applying this method to experimental data, we detect subtle conformational changes among chromosomes during differentiation of human stem cells.","subitem_description_type":"Other"}]},"item_10001_publisher_8":{"attribute_name":"Publisher","attribute_value_mlt":[{"subitem_publisher":"American Physical Society"}]},"item_10001_relation_14":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type":"isIdenticalTo","subitem_relation_type_id":{"subitem_relation_type_id_text":"info:doi/10.1103/PhysRevResearch.2.043078","subitem_relation_type_select":"DOI"}}]},"item_10001_relation_17":{"attribute_name":"Related site","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://journals.aps.org/prresearch/abstract/10.1103/PhysRevResearch.2.043078","subitem_relation_type_select":"URI"}}]},"item_10001_rights_15":{"attribute_name":"Rights","attribute_value_mlt":[{"subitem_rights":"© 2020 American Physical Society"}]},"item_10001_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"2643-1564","subitem_source_identifier_type":"ISSN"}]},"item_10001_version_type_20":{"attribute_name":"Author's flag","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_970fb48d4fbd8a85","subitem_version_type":"VoR"}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2020-12-01"}],"displaytype":"detail","filename":"Pigolotti-2020-Bifractal nature of chromosome.pdf","filesize":[{"value":"1.4 MB"}],"format":"application/pdf","license_note":"Creative Commons Attribution 4.0 International(https://creativecommons.org/licenses/by/4.0/)","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"Pigolotti-2020-Bifractal nature of chromosome","url":"https://oist.repo.nii.ac.jp/record/1816/files/Pigolotti-2020-Bifractal nature of chromosome.pdf"},"version_id":"9214cb1a-7d6b-47e4-a9da-00e9017cdbdd"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"eng"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"journal article","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"Bifractal nature of chromosome contact maps","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Bifractal nature of chromosome contact maps","subitem_title_language":"en"}]},"item_type_id":"10001","owner":"30","path":["77"],"pubdate":{"attribute_name":"公開日","attribute_value":"2020-12-01"},"publish_date":"2020-12-01","publish_status":"0","recid":"1816","relation_version_is_last":true,"title":["Bifractal nature of chromosome contact maps"],"weko_creator_id":"30","weko_shared_id":30},"updated":"2023-06-26T11:42:28.912283+00:00"}
