Photo-based facial recognition systems currently attract the attention of researchers all around the world. Their wide appeal no doubt has to do with their multiple applications, as they can be used, e.g. in security systems (for access control), the search for missing or wanted persons, as well as border control. Their development has intensified over the past two decades thanks to the ever wider availability of IT technologies, the ubiquity of surveillance cameras, increased computing power and improvements in data analysis methods, which allow the amount of information processed in digital images to be reduced.

Facial recognition requires highly complex computer techniques, as it needs to take into account a variety of factors that considerably affect the appearance of the human face, such as, to name but a few, the aging process, various natural and unnatural changes in the facial skeleton, face positioning, facial expressions, lighting, covered up parts, and even something as trivial as photo quality. Available recognition methods usually prove quite effective, but, unfortunately, only under nearly ideal test conditions, i.e. when tested with the use of photos gleaned from publicly available databases, in which all faces are lit in a similar way and successive shots of a given person are taken within a short time span. In this context, the research team proposed a theoretical study and implementation of new and original face classification algorithms, based on innovative granular computing methods and enriched with expert knowledge and psychological research on the importance of specific face parts in facial recognition in humans. This additional reliance on human cognitive processes in automatic face recognition was a crucial aspect of the project.

  • an effective local descriptor: Chain Code-Based Local Descriptor,
  • methods for weighting the importance of individual face parts in the recognition process and describing traits used in classification process with linguistic descriptors and the tools of decision theory, such as AHP,
  • a method for setting the optimal function parameters to aggregate the results of classifiers built for different face parts and based on different classification methods,
  • an analysis of the effectiveness of different aggregation functions, including the Choquet integral and its generalizations, in the classification process,
  • a proposal of graphical interfaces for selected decision theory tools.

We know the winners of the 2018 National Science Centre Award

Wed, 10/10/2018 - 23:00

Professor Bartosz Brożek, Professor Joanna Sułkowska and Professor Piotr Sankowski are the winners of the 2018 National Science Centre Award. Each will receive PLN 50,000 for outstanding academic achievements in the area of basic research. As usual, the ceremony was held at the Gallery of the 19th-Century Polish Art in the Sukiennice in Kraków.

Founded in 2013, the Award is bestowed upon researchers under the age of 40, with the objective of supporting the most outstanding individuals involved in basic research at the Polish research centres. The Award is presented in three research fields: Arts, Humanities and Social Sciences, Life Sciences and Physical Sciences and Engineering.

Professor Bartosz Brożek from the Department for the Philosophy of Law and Legal Ethics at the Faculty of Law and Administration of Jagiellonian University is this year's winner in the area of Arts, Humanities and Social Sciences. In his research, Professor Brożek also cooperates with the Copernicus Centre for Interdisciplinary Studies. The competition jury of the National Science Centre Award appreciated his innovative conception of normativity of law and other normative systems, based on philosophical argumentation and the findings of cognitive and evolutionary sciences. Professor Brożek's research interests also include theory and philosophy of law, as well as philosophy of science, language, and mind.

“My approach to research could be encapsulated in the following prescription: solve interesting and important problems with any tools you have at your disposal,” Professor Brożek explains. “I believe that no responsible reflection on law and philosophy is possible without achievements of contemporary cognitive science. In the past several dozen years, they have revolutionised our understanding of mind and the mechanisms of human behaviour.

Professor Joanna Sułkowska from the Centre of New Technologies and the Faculty of Chemistry at the University of Warsaw carried off the prize in the field of Life Sciences. She was recognised for her work on “knotted” proteins. The abnormal activity of “knotted proteins” may lead to various lifestyle diseases, and deciphering their secrets may bring about a breakthrough in the treatment of Alzheimer's disease, Parkinson's disease and obesity. Professor Sułkowska specialises in molecular and theoretical biophysics. Her research is interdisciplinary and relies on physical, mathematical and biological methods.

“In my work, it’s vital to be able to look at the big picture, without getting too attached to a single discipline, to see the protein structure not only through the eyes of a physicist, but also those of a biologist and chemist. You have to be able to imagine things you cannot see with the naked eye, even though they actually exist,” Professor Sułkowska says.

The third winner, Professor Piotr Sankowski from the Faculty of Informatics at the University of Warsaw, received the Award for his fundamental results in the area of graph algorithms, especially finding associations in graphs. His research interests focus on combinatorial optimisation, with an emphasis on dynamic and stochastic calculations and algorithm engineering.

“Algorithms play an increasing role in our life. They select the information we see on websites, offer us customised ads and decide the prices in online stores and supermarkets,” Professor Sankowski explains. “The great challenge before us is to understand how to do it well and especially how to guarantee that the algorithms we use are fair.”

Candidates for the Award are nominated by scientists, e.g. former Board members of the National Science Centre, former heads of the Expert Teams at the National Science Centre, previous winners, as well as other eminent representatives of the world of science selected by the Board and the Director of the National Science Centre. In this edition, 497 people were eligible to nominate candidates. There were 69 nominations submitted; the shortlist included 6 finalists, two in each of the three disciplines. The final decision was taken by the competition jury of the National Science Centre Award, composed of the representatives of the National Science Centre and the donors of the Award.

The Award also builds bridges between the worlds of science and business. Every year, the National Science Centre invites the cooperation of enterprises involved in social and research activities, which play the role of benefactors and fund the prize of PLN 50,000 for each winner. This year, these have included the Adamed Group, Jastrzębska Spółka Węglowa, and Fundacja KGHM Polska Miedź.

Five calls for proposals with the budget of PLN 530 M open

Fri, 09/14/2018 - 15:47

This is the sixteenth time that the National Science Centre (NCN) has opened a new call for proposals within the OPUS and PRELUDIUM funding schemes, and the fourteenth time within the SONATA scheme. A total of PLN 480 million is available in all national calls. In addition, BEETHOVEN CLASSIC 3 and a new program, BEETHOVEN LIFE 1, are launched in cooperation with the German Research Foundation. International schemes offer grants up to a total amount of PLN 50 million. Altogether, applicants in the recently announced calls will vie for a record total of PLN 530 million.

Following the success of the previous two editions of the BEETHOVEN call, a new edition is launched this year under a new name, but with the same conditions. BEETHOVEN CLASSIC 3 is targeted at Polish-German research projects in arts, humanities and social sciences, as well as the selected disciplines in physical sciences and engineering. The call’s budget, organised in cooperation with the German Research Foundation (Deutsche Forschungsgemeinschaft, DFG), amounts to PLN 30 million.

A new addition to the call portfolio, BEETHOVEN LIFE is designed as a supplement to BEETHOVEN CLASSIC, and is aimed at scholars involved in life sciences. For the Centre, it will be the first call conducted on the basis of the Lead Agency Procedure, and the DFG will play the role of the lead agency in the first edition. The German agency will have the sole responsibility for scientific assessment, while the National Science Centre will accept national proposals for the funding of the Polish part of research projects in question. A total of PLN 20 million is available within the BEETHOVEN LIFE call.

“We are happy that our cooperation with the German Research Foundation has now been expanded to include a call in the life sciences. This rounds out our offer for researchers cooperating with the German side”, says Professor Zbigniew Błocki, Director of the National Science Centre, “Our office will have a chance to test the Lead Agency Procedure in practice and see whether it facilitates and expedites the assessment of submissions in calls organised in cooperation with foreign partners. In the future, we would like to implement the same system in all such calls.”

Apart from international funding opportunities, the National Science Centre also announced its flagship national calls: OPUS, PRELUDIUM and SONATA. The budgets of all three calls have been substantially increased in this edition with PLN 350 million to be distributed in OPUS 16, 40 million in PRELUDIUM 16, and PLN 90 million in SONATA 14.

OPUS, PRELUDIUM and SONATA are the most popular calls in the National Science Centre offer. The quality of submitted proposals gets better and better every year and it is not unusual for good projects to be rejected because of insufficient funds, which is why it has been so important for us to increase the budget and thus give many more valuable projects an opportunity to get off the ground”, says Professor Janusz Janeczek, Chairman of the Council of the National Science Centre.

The OPUS 16 funding scheme is open to all researchers, irrespective of their academic level. Within the framework of the project, they may receive funds to hire a research team to work on a given subject matter, as well as purchase or construct the research equipment necessary for the project. Young researchers are also eligible for special fellowships.

PRELUDIUM 16 is dedicated to researchers at the outset of their academic career, who do not yet have the title of doctor. Doctoral students may conduct an independent research project for one, two or three years, not necessarily connected to the subject of their doctoral thesis. The maximum funding for a single project equals, respectively, PLN 70,000, 140,000, or 210,000.

Last, but not least, SONATA 14 is addressed to scholars who earned their doctoral degree between 2011 and 2016 and aims to support them in conducting innovative research with the use of state-of-the-art equipment and original methodology. This edition has done away with the obligatory interviews with principal investigators at the second stage of the assessment process.

Effective as of the new calls announced in September, the Council of the National Science Centre has introduced important changes into the job funding requirements within NCN’s calls. An additional condition has been formulated for post-doc applicants. They must not have had an employment contract with the entity where the research project is to be conducted within 2 years prior to their post-doc.

“The change is designed to create the conditions for increased researcher mobility, both on the national and international scale. The opportunity to cooperate with scholars representing other experiences and work cultures benefits the entire research team and improves the quality of the research project”, says Professor Janeczek.

Proposals should be submitted by means of the ZSUN/OSF system (https://osf.opi.org.pl) until 17 December 2018.

  • OPUS 16 call for proposals for research projects, including purchase or construction of research equipment necessary for their completion
  • PRELUDIUM 16 call for proposals for research projects conducted by researchers at the beginning of their career in research, who do not hold a doctorate degree.
  • SONATA 14 call for proposals for research projects carried out by researchers who have been awarded a doctorate within 2 to 7 years before submitting the proposal
  • BEETHOVEN CLASSIC 3 for Polish-German research projects within humanities, social sciences, chemistry, physics, mathematics and material sciences. 
  • BEETHOVEN LIFE 1 for Polish-German research projects within life sciences.

Polish scientists with their publication in prestigious magazine

Fri, 08/24/2018 - 15:21

We are pleased to inform you that one of the most prestigious scientific magazines in the world – “Cell” – has published an article written by a team of Polish scientists from the Institute of Biochemistry and Biophysics of the Polish Academy of Sciences in Warsaw (IBB PAN). This is the second publication in its history to have a Polish mailing address in the magazine, the first having been published in 1990.

The first author of the publication and originator of the research project was Dr Zbigniew Warkocki. The other members of the team were Dr Paweł Krawczyk, Dorota Adamska, Krystian Bijata and Jose L. Garcia-Perez and the project was supervised by Prof. Andrzej Dziembowski.

The article published in “Cell”, entitled Uridylation by TUT4/7 Restricts Retrotransposition of Human LINE-1s, concerns the mechanisms of defence against the so-called jumping genes (retrotransposons) which were described for the first time by the Polish researchers. The retrotransposons are DNA fragments that constitute characteristic parasites in cells, they are completely useless, and even harmful. Earlier descriptions involved the manner of inhibition by a cell of DNA fragment activity, which leads to the multiplication of harmful retrotransposons, whereas, at present, the Polish scientists have explained how a cell may defend itself against these genetic parasites during a further stage, when a retrotransposon has already activated.

The research conducted by the team lead by Prof. Dziembowski was, to a great extent, financed by the National Science Centre within the FUGA 1 grant, during which Dr Warkocki came from Germany for an placement in IBB PAN. The research was also financed from the two grants received by Prof. Andrzej Dziembowski: the ERC Starting Grant and the TEAM grant by the Foundation for Polish Science TEAM. Prof. Dziembowski is also a grantee of the National Science Centre and a 2013 NCN prize-winner.
