Combinatorial problems -- a place where classical enumeration fails
Abstract:
Combinatorial problems are, by their very nature, interesting and daunting at the same time. These types problems are approachable and can be explained with very little technical background and yet one can ask deep questions that require powerful machinery to approach answers and solutions to such questions. In this talk we consider two such problems. One considers symmetries of graphs and generalises these concepts to the realm of permutation group theory and so-called "r-regular families of permutations". This project is continued work from previous years and we will report on our progress. The second problem generalises the classical antidictionary problem, where one wishes to distinguish between words that do not contain certain subwords and the ones that do, into two dimensions. This technique developed to tackling the classical antidictionary problem is useful in searching algorithms, especially the ``string searching'' algorithms. We will also see a famous class of graphs, so-called de Bruijn graphs, and how they are related to this two dimensional problem.  More information Youtube channel ]]> [FMFI] Prednášky a semináre [FMFI] Kalendár Damas.Gruska@fmph.uniba.sk Wed, 19 Nov 2025 08:32:00 +0100 https://uniba.sk/ The Department of Anatomy at the Jessenius Faculty of Medicine, Comenius University in Martin...

Analysis of elemental composition of atmospheric aerosols using the PIXE method with an external ion beam
Abstract:
The study of the elemental composition of atmospheric aerosols contributes to the understanding of the development of environmental pollution. The CENTA facility, equipped with a 3 MV tandem accelerator, is continually advancing techniques for elemental sample analysis. The PIXE method utilises an external beam, which is currently implemented through modifications of the accelerator system that enable the beam to exit the vacuum chamber. This method allows the analysis of a broad spectrum of samples, which are not constrained by size or composition. The technique was used to determine the concentration of several elements in aerosol samples taken at a meteorological station near the FMFI. Analysis of samples from different periods indicates a long-term trend in the evolution of concentrations of some elements, and at the same time reveals atypical events. ]]> [FMFI] Prednášky a semináre [FMFI] Kalendár Jaroslav.Stanicek@fmph.uniba.sk Thu, 13 Nov 2025 09:55:00 +0100 https://uniba.sk/ Friday 14.11.2025 at 13:15, Lecture room M VIII (online too) Maruša Lekše (University of Ljubljana, Slovenia):

Professor Pilmane has been leading this institute—comprising more than 75 employees—since 2009, following the merger of the previously independent Institutes of Anatomy, Histology, and Embryology. She is the author of over 200 indexed scientific publications, and her research focuses primarily on the development and congenital malformations of the face. She has authored several textbooks on embryology and developed modern, innovative teaching methods in anatomy. She initiated the establishment of a unique collection of anatomical exhibits within the institute, known as Theatrum Anatomicum Rigense. Her research in the field of implantable bone substitute materials for use in oral and maxillofacial surgery was recognized with the Certificate of Recognition from the President of the Latvian Academy of Sciences as the most significant scientific achievement of 2019. Professor Pilmane is an elected member of the Latvian Academy of Sciences, and in 2022 she received from the President of the Republic of Latvia the Order of the Cross of Recognition, with the title Officer of the Cross of Recognition, for her outstanding contributions to the state, society, education, and science. On 11 November 2025 at 13:30, in the Main Lecture Hall of the New Theoretical Institutes Building (Sasinkova Street 4), Prof. Māra Pilmane will deliver a lecture titled:

Validation and verification of carbon-14 determination method in samples from nuclear facilities
Abstract:
Carbon-14 is an activation product with a long half-life and is one of the radiochemicaly complicated and difficult to measure radionuclides due to the low energy of beta radiation (156.469 keV) and its presence in various chemical forms. When monitoring gaseous discharges from nuclear installations, C-14 activity in samples obtained by capturing gaseous chemical forms of carbon into NaOH solution is evaluated and balanced. The aim of the work was to optimize and validate a method for determining C-14 activity in liquid matrices of gaseous discharges using liquid scintillation spectrometry. The method was successfully verified in the interlaboratory comparative test "Environmental Radioactivity Proficiency Test Exercise 2021" at the Radiochemical Analysis Test Laboratory of KJCH Prif UK, which holds accreditation according to STN EN ISO/IEC 17025:2017. The application to real samples from the gaseous outlets of the nuclear power plant confirmed that the method meets all the requirements of the standard. ]]> [FMFI] Prednášky a semináre [FMFI] Kalendár Jaroslav.Stanicek@fmph.uniba.sk Thu, 06 Nov 2025 11:59:00 +0100 https://uniba.sk/ Monday 10.11.2025 at 13:10 hod., Lecture room I 9 Filip Kerák:
Shrinking the giants - Sparse Neural Networks a necessity of the future
Abstract:
How to live long enough to understand the ultimate question of life universe and everything... Modern neural networks often comprise billions of parameters, resulting in substantial time and computational demands during both training and inference. While these large-scale models have achieved remarkable success across a wide range of tasks, their size and resource requirements pose significant challenges for broader adoption and sustainability. A promising solution lies in reducing the size of these models. Strategies like lowering precision or quantization can only by applied to a certain point, therefore minimizing the number of parameters without sacrificing accuracy is a growing next step. One effective approach is to introduce sparsity during training. By selectively retaining only the most essential connections, sparse training techniques can produce models that are significantly smaller and faster, yet still highly capable.

Hopf algebras and quantum principal bundles Abstract:
I will give a gentle introduction to the theory of Hopf--Galois extensions and explain their geometric interpretation as noncommutative principal bundles. If time permits, I will review a differential calculus approach for quantum principal bundles, which gives rise to horizontal and vertical forms, together with a noncommutative Atiyah sequence. Examples, such as the quantum Hopf fibration, will be discussed. This is partially based on a collaboration with Antonio Del Donno and Emanuele Latini ]]> [FMFI] Prednášky a semináre [FMFI] Kalendár Peter.Matak@fmph.uniba.sk Tue, 04 Nov 2025 16:54:00 +0100
