Announcement on Japanese Consumption Tax (JCT)
This serves to announce to our valued authors based in Japan that value-added tax, or consumption tax will now be imposed on article processing fees and other service fees for all papers submitted, or resubmitted (assigned new paper IDs), effective from 15 August 2021. The change is in accordance with the Japanese "Act for Partial Revision of the Income Tax Act and Other Acts" (Act No. 9 of 2015), which includes a revision of consumption taxation on cross-border supplies of services such as digital content distribution.
For additional information from the National Tax Agency please see here ("Cross-border supplies of electronic services").

MDPI will be attending the CPS Fall Meeting 2021 in Lanzhou, China, on 21–24 October 2021. The theme of the conference is to enhance the academic exchanges of the domestic physics community, improve the academic level, promote the overall development of physics, and improve the quality of talent training. The conference was established 20 years ago, and the number of participants has gradually grown from the initial scale of 200 people at the first conference to the current scale of more than 5000 people. The Autumn Conference has also become the largest and most comprehensive brand academic event in China’s physics community.
The following MDPI journals will be represented:
If you are attending this conference, please feel free to stop by our booth B39. Our delegates look forward to meeting you in person to answer any questions you may have. For more information about the conference, please visit: http://www.lzu2021.cpsjournals.cn/.

Meet Us at the Virtual Charged Higgs Online Workshop on the Theme “Status of Charged Higgs Searches at the LHC and Physics Prospects for the Charged Higgs at HL-LHC”, 30–31 August 2021

Symmetry will attend this online workshop virtually, 30–31 August 2021.
The plan is to bring together experimentalists and theorists to review the present status of charged Higgs searches at the LHC and assess new theoretical developments and ideas at the LHC and beyond. We will review analysis methods, theory/phenomenology developments, generator-level simulations, and strategies for future experimental data analysis. We are aiming at a lively, instructive and fruitful workshop.
The proceedings and invited papers will be published in the Special Issue "Symmetry, Collider Phenomenology and High Energy Physics" of the “Physics and Symmetry” Section of Symmetry, an international, peer-reviewed, open-access journal of MDPI.

Book Builder—Compile a Customized E-Book from Your Favorite MDPI Open Access Content
MDPI Books recently released Book Builder, a new online tool to conveniently arrange, design and produce an eBook from any content published in MDPI journals. Book Builder offers two functions: on the one hand (1) Selections, available to every registered user of MDPI; on the other hand (2) Special Issue Reprints, which can be used exclusively by Guest Editors of Special Issues.
Selections
In just a matter of a few clicks, all users are now able to assemble books from MDPI articles and receive instantaneous feedback in the form of a fully produced and compiled book (PDF), which can be downloaded or ordered as print copy. Selections can include any paper published with MDPI, picking and combining content from different journals and special issues.
This way, the user may for example choose to compile an ebook focusing around a particular topic, or assemble articles from a group of others.
We invite you to make yourself familiar with the new tool! The Book Builder can be found here: https://www.mdpi.com/books/book_builder.
Special Issue Reprints
The Book Builder allows Guest Editors of MDPI journals to create a reprint from a successfully completed Special Issue or Topical Collection in book format. If you are a Guest Editor for an MDPI journal, you can use the new tool to create an PDF document which includes all articles published in the Special Issue as well as a book cover and table of contents.
For Special Issues containing a minimum of 5 articles, the Guest Editor can request its publication on the MDPI Book platform. Published reprints are assigned an ISBN and DOI.
In addition to the PDF copy of the Reprint Book, as a token of our gratitude, MDPI offers every Guest Editor one (1) complimentary print copy (via print-on-demand). All contributors benefit from a discount on orders of any additional print copies, to share with colleagues or libraries or others.
In line with our organization's values, MDPI Books publishes all content in open access, promoting the exchange of ideas and knowledge in a globalized world. MDPI Books encompasses all the benefits of open access—high availability and visibility, as well as wide and rapid dissemination. MDPI Books are distributed under the terms and conditions of the Creative Commons Attribution License, meaning as an author you retain the copyright for your work. In addition, with MDPI Books you can complement the digital version of your work with a high-quality printed counterpart.
If you are interested in editing a book volume or series, or have a monograph manuscript to be considered for publication, please submit your proposal online and look at our Information for Authors.

MDPI Celebrates Company Milestone With 25th Anniversary Page
"We exist to help scientists achieve their own objectives"

In June of this year, MDPI will celebrate the 25th anniversary of its foundation. To mark this significant milestone, we have created a 25th Anniversary page on our website that evokes the development of our company over the past quarter-century.
MDPI has been a pioneer of Open Access publishing ever since the concept was first created.
In a wide-ranging interview, our CEO Delia Mihaila reflects on the company’s 25th anniversary and its contribution to the world of scientific publishing.
Delia considers how MDPI has evolved since starting life in 1996 as a visionary ‘project’ run out of an apartment in Basel, Switzerland, by Dr. Shu-Kun Lin. A chemist who was passionate about the long-term preservation of rare chemical sample, Dr. Lin was determined to help scholars publish their findings as quickly as possible and make their research results available to as wide a readership as possible worldwide. That determination remains unchanged 25 years later.
Today, MDPI is an international organization with over 4,000 employees based on three continents and in ten countries, and ranks among the world's top four academic publishers.
MDPI's mission is to accelerate access to new scientific research, delivering insight faster for researchers worldwide. Read more here about the company's remarkable success story and what the Open Access publishing model can offer the global scientific community.
