Announcements

Second order partial differential equations (PDEs) with nonnegative characteristic form appear to be ubiquitous in mathematics, e.g., in differential geometry, stochastic theory, and in many applications of mathematics, e.g., kinetic theory and finance. Important special cases of such operators are those satisfying Hormander's condition. They enjoy regularity properties related to the suitable geometric structure of the underlying space. The more we know about geometric structures, the better for regularity results, bounds, and asymptotic estimates. The goal of the webinar is to show recent results and advances in the field of PDEs. We believe that the mathematical community will benefit from the webinar.

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 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.

At MDPI, we strive to make your online publication process seamless and efficient. To achieve this, our team is continuously developing tools and features to make the user experience useful and convenient.

As the number of academic papers continues to grow, so does the need to analyze and work with them on a large scale. This prompted us to design a new feature aimed at helping researchers find journals that are relevant to their publication by matching their abstract topic. In this regard, we designed a similarity model that automatically identifies the most suitable academic journals for your paper.

We are pleased to introduce Journal Selector, a new feature that measures similarity in academic contexts. By simply entering the title and/or abstract into our Journal Selector, the author will see a list of the most related scientific journals published by MDPI. This method helps authors select the correct journals for their papers, highlighting the time of publication and citability.

The methodology is known as representation learning, where words are represented as vectors in hyperspace. Representation helps us differentiate between different concepts within articles, and in turn, helps us identify similarities between them.

We used an advanced machine learning model to better capture the semantic meanings of words. This helps the algorithm make better predictions by leveraging scientific text representation. In turn, this ensures high precision, helping authors decide which journal they should submit their paper to.

The goal is to support authors to publish their work in the most suitable journal for their research, as fast as possible, accelerating their career progress.

We are pleased to announce that Mathematics will become a semimonthly publication on 1 January, 2021. Semimonthly publication allows papers to be indexed in Web of Science and other indexing databases on a semimonthly basis, rather than on a one month period, and so they become searchable and are citable earlier. We would also like to acknowledge the many valuable publications from our authors and the important contributions of our dedicated reviewers.

MDPI is proud to adopt the principles of the Coalition for Diversity & Inclusion in Scholarly Communications (C4DISC) to support building equity, inclusion, diversity, and accessibility in scholarly communications.

The C4DISC represents organizations and individuals working in scholarly communications and is focused on addressing issues of diversity and inclusion within the publishing industry.

MDPI’s Managing Editors encourage the Editors-in-Chief and Associate Editors to appoint diverse expert Editorial Boards. This is also reflective in our multi-national and inclusive workplace. We are proud to create equal opportunities without regard to gender, ethnicity, geographic location, sexual orientation, age, disability, political beliefs, religion, or socio-economic status. There is no place for discrimination in our workplace and editors of MDPI journals are to uphold these principles in high regard.

Representatives from C4DISC meet monthly, and have started to implement initiatives to shed light and improve on the lack of diversity in scholarly communications. Some of the initiatives include developing a joint statement of principles; conducting market research; providing training resources, best practices, toolkits, and documentation for our collective memberships; and establishing outreach programs, curricula, events, and publications.

The Coalition is committed to:

• eliminating barriers to participation, extending equitable opportunities across all stakeholders, and ensuring that our practices and policies promote equitable treatment and do not allow, condone, or result in discrimination;
• creating and maintaining an environment that respects diverse traditions, heritages, and experiences;
• promoting diversity in all staff, volunteers, and audiences, including full participation in programs, policy formulation, and decision-making;
• raising awareness about career opportunities in our industries to groups who are currently underrepresented in the workforce;
• supporting our members in achieving diversity and inclusion within their organizations.
