Theoretical and Natural Science (TNS, ISSN: 2753-8818) is an international open access journal. All of our articles are published under a Creative Commons (CC BY) license, meaning all articles published in TNS can be freely read, downloaded, cited and distributed on the journal website. EWA Publishing ensures that no university library or individual needs to pay a fee to obtain access to articles in this journal, so TNS does not receive any revenue from the publication of articles.
In order to provide free access to readers, and to cover the costs of peer review administration and management, copyediting, typesetting, long-term archiving, journal management, and dissemination of published papers in various venues, in addition to other publishing functions, a one-time Article Processing Charge (APC) of 380 USD (US Dollars) applies to papers accepted after peer review, excluding taxes. The prices quoted do not include any value-added tax (VAT), goods and services tax (GST), or other sales taxes. Local VAT or Sales Tax may be charged in addition to the price shown where required by law. The amount of tax charged will be calculated at the point of sale and identified separately. Authors from Switzerland will have the local Value Added Tax (VAT) added to their invoices. Japan residents will have the Japanese Consumption Tax (JCT) added to their invoices at the rate set by the Japanese government.
And no fee will be charged before the manuscript is accepted, such as editorial processing charge, submission fee, page fee, etc.
In addition, there are no charges for rejected articles, no submission charges, and no surcharges based on the length of an article, figures or supplementary data. Some items (Editorials, Corrections, Addendums, Retractions, Comments, etc.) are published free of charge.
Color figures may be published online free of charge; however, the journal charges for publishing figures in color in print. The first two figures may be printed without charge, whilst the third figure printed for $150, and all subsequent figures for $50. If the author does not explicitly request color figures for publication, figures will be converted to black and white for print publication by default.
