Welcome message by Prof. Dr. Konstantin Zioutas, Webinar Chair:

Physics is full of unanswered questions. In space science, we are faced with a large number of observations of unknown origin, even within our solar system. We recall, as an example, the historic observation in the 1930s by Fritz Zwicky of some suspected matter in the universe, which he called “dunkle Materie”, also known as dark matter. Dark matter (DM) dominates the universe, with its mass being about five times that of the normal matter we, the planets, the stars, etc., are made of. After 90 years, we can only suspect the microscopic constituents of DM, and assume that it interacts gravitationally. Thus, we live inside a well-hidden, dark universe. Undoubtedly, it is of utmost importance to identify the nature of DM. Therefore, it is safe to predict that the expected discoveries at present will overshadow historical discoveries. This is a challenge but also a unique opportunity for people fascinated by the unknown. The study of DM is exciting and highly motivating. In particular, for young people faced with the decision of choosing an exciting and rewarding career, astroparticle physics might just be the choice. Delving deeper into this exploration of DM, we pose some questions that we excitedly await the answers to:

What is dark matter? What is dark energy? Why is there an arrow of time? Are there parallel universes? Why is there more matter than antimatter? What is the fate of the universe? Is string theory correct? Do the universe's forces merge into one? What happens inside a black hole? What lies beyond the Standard Model? Fundamental constants? Do living things sense the dark universe?  

In this webinar, we will hear from two experienced physicists (Prof. Dr. Ariel Zhitnitsky, Canada, and Prof. Michael Tobar, Australia), as well as two physicists who are just beginning their promising careers in this area (Prof. Dr. Abaz Kryemadhi, USA, and Dr. Javier Miguel, Spain).

All four speakers work at the forefront of physics research, and therefore they will provide an appropriate introduction to this topic.

Date: 25 May 2023 at 4:00 p.m. CEST | 10:00 a.m. EDT | 10:00 p.m. CST Asia

If you are attending this conference, please visit our booth. Our delegates look forward to meeting you in person and answering any questions that you may have. For more information about the conference, please visit the following link: https://gefes2023.es/.

We are pleased to announce the winner of the Symmetry (ISSN: 2073-8994) 2022 Young Investigator Award—Prof. Dr. Yao Chen.

Prof. Dr. Yao Chen was born in 1986, obtaining his bachelor’s degree and Ph.D. at the Southeast University in 2007 and 2014, respectively. He then became an Associate Professor of Southeast University in 2017 and a Full Professor in 2020. During these years, he has made academic visits to the University of Cambridge, Tokyo University, MIT, Caltech, etc., and obtained the Humboldt Research Fellowship in 2018–2020. Currently, he is a committee member of IASS WG6, WG13, and ASCE/EMI. His research interests include advanced structures (e.g., tensegrity, origami, kirigami, deployable structures), computational symmetry methods (e.g., group theory, graph products), computational mechanics, and the mechanics of materials.

Please join us in congratulating Dr. Yao Chen for his outstanding achievements.

We would like to thank the award committee for their excellent work in the hard task of selecting a winner from such a large number of excellent candidates. We also thank all the nominees from various fields for their participation. We will continue to reward young scientists with the Young Investigator Award and wish them every success in their careers.

For more information about Symmetry awards, please refer to the following link: https://www.mdpi.com/journal/symmetry/awards.

The following is a short Q&A with Prof. Dr. Yao Chen:

1. What does your current research concern and why did you choose this field?

My current research project is about novel design and folding behavior of origami-inspired structures, which has been supported by the NSFC of China and the Humboldt Research of Germany. Because origami neatly describes the mathematics and mechanics of an ancient art about folding paper in China and Japan, it exhibits remarkable geometric transformations, periodic symmetry, programmable stiffness, negative Poisson's Ratio, etc. Owing to these characters, origami structures and metamaterials can be extensively applied into different fields, including engineering structures, solar panels, mechanisms and robotics, and flexible electronics.

2. Which research topics do you think will be of particular interest to the research community in the coming years?

Robust and intelligent design using AI, 3D printing, novel structures and materials.

3. Have you ever encountered any difficulties when conducting your research? How did you overcome them?

Yes. There will always be certain difficulties in our scientific research. Do not lose heart, do not be timid. Just investigate carefully and seek comments and suggestions from others. Then, analyze and solve the problem.

4. What qualities do you think young scientists need today?

We need qualified scientists with carefulness, strictness, professional responsibility, team-spirit and the ability to cooperate, plan short and long-term, etc.

5. Symmetry is an Open Access journal. How do you think Open Access journals impact authors?

Symmetry is a well-renowned international journal. I’ve known about this journal for 12 years and noticed many well-known researchers and experts from Symmetry who published their work in this journal. In my view, Open Access journals are much more conducive to reading, citing and sharing. Thus, new research results published by OA journals can be efficiently and easily noticed. However, it is necessary to strictly control the quality of submitted manuscripts and pay attention to the improvement of the overall reputation for each OA journal.

We are pleased to announce the launch of a new initiative—the MDPI Special Issue Mentor Program.

This program will enable early career researchers (who must hold a Ph.D. in a related field) to experience editing a Special Issue in MDPI journals, under the mentorship of our experienced Editorial Board Members or other experienced scientists. The mentor program will provide an excellent opportunity for early career scientists to gain editorial experience, and to cultivate their ability to edit scientific research.

The mentee’s responsibilities include:

• Proposing a Special Issue title and assisting the mentor in preparing a summary (around 200–400 words) and 3–10 keywords describing the background, importance, and goal of the Issue;
• Writing a brief promotion plan for the Special Issue;
• Preparing a list of scholars who may be interested in the Issue and personally e-mailing invitations on behalf of Guest Editors;
• Writing an editorial for the online Special Issue together with the mentor.

The mentor’s responsibilities include:

• Conducting a final check before the Special Issue is published online;
• Performing editorial control of the Special Issue and quality control of the publications, both of which must be carried out in a timely manner;
• Providing suggestions to younger scholars if they have any doubts or concerns regarding submissions;
• Organizing video calls with young scholars and the Editorial Office regularly to discuss problems and improvement suggestions for the Special Issue;
• Making and submitting decisions regarding submissions with the assistance of mentees.

Certificates and awards:
After the Special Issue closes, the Editorial Office will provide official certificates for all the mentors and early career researchers.

If you are interested in this opportunity, please send your Special Issue proposal to the Editorial Office of a journal you choose, and we will discuss the process (i.e., mentor collaboration, Special Issue topic feasibility analysis, etc.) in further detail. The full list of MDPI journals is as follows: https://www.mdpi.com/about/journals.

In addition to the new Special Issue Mentor Program, we will continue to welcome all Special Issue proposals focusing on hot research topics.

We are pleased to announce that Prof. Dr. Dongfang Li has been appointed Associate Editor of the “Mathematics and Symmetry/Asymmetry” Section in Symmetry (ISSN: 2073-8994). We wish Prof. Dr. Dongfang Li every success in his new position and we look forward to his contributions to the journal.

Mathematics is central to modeling problems from other areas. It is the language that scientists use to understand the world. Symmetries often appear in mathematical formulations and become essential for solving problems or delving further into research.

The main aim of this Section is to present fundamental and frontier theories and techniques for modern science and technology. It will stimulate research interest for the exploration of mathematical applications and directly pass new knowledge to the next generation. The objective of this Section is to present high-quality studies that use non-trivial mathematics and apply their symmetries to relevant problems from all areas. Among others, papers on these topics are welcome:

• Dynamical systems;
• Mathematical physics;
• Geometrical and topological methods;
• Applied mathematics;
• Discrete mathematics and graph theory;
• Mathematical analysis.

Prof. Dr. Dongfang Li is now leading the Special Issue "Symmetric Methods and Analysis for Differential and Integral Equations", in which feature papers will be published.

MDPI has just become the first open access (OA) publisher to reach the milestone of one million articles published. That is one million articles freely available to all, to circulate and build upon! We are proud to share this special moment with the global scientific community.

This landmark has been reached thanks to the immeasurable support of more than 600,000 expert reviewers, 66,000 editorial board members and 6700 hard-working colleagues across MDPI’s global offices.

Within more than 25 years of publishing, our journals received 2.1 million manuscripts and generated 4.6 million peer review reports to get to one million papers published.

Reaching the milestone of one million articles published reinforces our mission to remove any existing barriers and to make scientific research accessible to all. Since its inception, MDPI’s goal has been to create reliable processes to make science open. This is a path towards facilitating the dissemination of novel insights in scientific communities.

Regular feedback from authors and reviewers shows that our service is greatly appreciated and needed. At the same time, the feedback helps us identify areas for further improvement.

As it stands, a significant share of published research findings remain closed access. More than half of the content published with the most well-known legacy publishers stays behind a paywall, and that is not including articles published in hybrid OA journals, or made available months or years after publication.

A new policy announced by the US administration in August 2022 requires that, as of January 2026, all US federally funded research be made freely and immediately available after publication. While the new policy does not mandate articles be published under an open access license, it is aligned with the open access movement in removing all barriers to research. Similarly, some of the most advanced research institutions in the world intend to have all funded research articles published in open access by 2025.

MDPI is proud to be the leading agent of the transition to open access.

"Thanks a Million" to all the contributors!

We are pleased to announce that the website of the MDPI Sustainability Foundation has been revamped! For the past couple of months, our UX UI team and front-end developers have been working hard to launch the website in time for the opening of the Sustainability Awards nominations.

The website is not the only thing that has had a remodeling. Indeed, the format of the Emerging Sustainability Leader Award (ESLA) has been updated. ESLA is now a competition open to individual researchers or start-ups founded by researchers under the age of 35. Nominee applications will go through 2 rounds of selection until the final 3 are decided. The finalists will then be invited to give pitch presentations during the Award Ceremony to win either first place (10,000 USD) or runner-up (2 x 5000 USD).

The World Sustainability Award, on the other hand, remains the same: a total prize money of 100,000 USD is up for grabs by senior individual researchers or groups of researchers from the international research community.

Nominations for both the World Sustainability Award and the Emerging Sustainability Leader award are now open! Check out our new website for more information on how to nominate.

Recently, Clarivate^TM revealed its 2022 list of Highly Cited Researchers^TM—individuals at universities, research institutes and commercial organizations.

Based on Web of Science Citation data, 6,938 researchers from across the globe who have demonstrated a disproportionate level of significant and broad influence in their chosen field or fields over the last decade have been awarded Highly Cited Researcher 2022 designations. The list is truly global, spanning 69 countries or regions and spread across a diverse range of research sciences and social sciences.

According to statistics, 12 members of the Editorial Board of Symmetry (ISSN: 2073-8994) have been selected into the list of Highly Cited Researchers of Clarivate in 2022. They are being recognized for their high-quality scientific research achievements and outstanding contributions to professional fields. The Symmetry journal office sincerely congratulates all elected Editorial Board Members and hopes that they continue to have an academically productive relationship with the journal.

Stanford University has recently published an update of the list of the top 2% most widely cited scientists—The World’s Top 2% Scientists.

The timeline of the statistical data of this list is from 1960 to 2022, and it is divided into two lists: "Lifetime Scientific Influence Ranking" and "2022 Annual Scientific Influence Ranking". The "Lifetime Scientific Influence Ranking" lists the comprehensive influence performance of scientists during their careers, and the "2022 Annual Influence Ranking" highlights the academic influence of scientists in the previous year. This ranking, considered the most prestigious worldwide, is based on the bibliometric information contained in the Scopus database and includes more than 200,000 researchers from the more than 10 million scientists considered to be active worldwide, with 22 scientific fields and 176 subfields taken into account.

We are pleased to share that 191 Editorial Board Members from MDPI’s journal Symmetry (ISSN: 2073-8994) were featured in Stanford’s List of the World’s Top 2% Scientists in 2022.

1. What appealed to you about the journal that made you want to take the role as its Section Editor-in-Chief?

The journal Symmetry has developed to become one of the leading journals in physics, engineering and computer science in the last 12 years, achieving high-impact factor and quarterly indices. Being Section Editor-in-Chief is a demanding and challenging task, in a field with continuous changes and considerable competition, but my main aim is excellence in the published research in the journal. Scientific excellence in scientific journals is the main aim of any successful editorial team.

2. What is your vision for the journal?

My vision is to further strengthen the appeal and soundness of the journal in engineering science. The academic developments in engineering science in our times are striking, and my vision is focused on publishing state-of-the-art articles in the journal, making Symmetry one of the leading journals in engineering science.

3. What does the future of this field of research look like?

Engineering science is constantly changing every year, and thus the future seems promising from a scientific point of view. My motivation is excellence in published research and, thus, our editorial team aims to make Symmetry a leading and up-to-date database of excellent research articles in the field.

4. What do you think of the development of Open Access in the publishing field?

The journal Symmetry supports Open Access science, and Open Access publishing schemes are, in my opinion, the future of scientific research, since the author holds the copyright of his research. Open Access schemes can be further modified with the synergy of journals and academic institutions, offering individual authors the possibility of retaining the copyright.

We wish Prof. Dr. Oikonomou every success in his new position, and we look forward to his contributions to the journal.
