Cognitive neuroscience is a fast developing scientific field which aims at uncovering the neural basis of human perception and cognition. To achieve this goal, cognitive neuroscience uses a variety of tools and approaches ranging from non-invasive brain imaging to psychophysics and neural modeling. Mastering such tools requires skills and knowledge from multiple scientific domains, including neurophysiology, cognitive psychology, and several computational fields.

Over the past several decades, significant advances have been made in particular in the imaging and computational fields, providing us with large amounts of data about the brain function, with tools to analyze them, and, in turn, with a multitude of new advances in our understanding of the neural information processing. This proceedings provides a snapshot of our current knowledge in cognitive neuroscience, focusing on the mechanisms of auditory and cross-modal perception. It contains a collection of introductory lectures, research talks, and lab assignments prepared by invited experts in this field for two editions of a workshop and lecture series on “Cognitive neuroscience of auditory and cross-modal perception” that took place in Košice in 2014 and 2015. It is aimed at students and early-stage researchers interested in obtaining an overview of the basic knowledge, current research questions, and methods used in auditory and cross-modal perceptual research.
Each invited expert prepared one introductory lecture providing overview of his/her expertise, one advanced lecture on a current research topic, and an assignment related to his/her research. These teaching materials are provided in the first two parts of the proceedings. The third part provides abstracts of contributed presentations by the workshop participants. In addition, the accompanying CD and web provides the code and/or data of the assignments. The lectures only contain slides of the individual talks, and thus only provide an outline of the research topics and cannot be used as a textbook. For a reader interested in working on an assignment it is useful to first read through the corresponding lectures by the same author which contain a broader introduction to the selected problem. Most of the assignments code is in MATLAB and requires basic familiarity with this environment.
Additional information about this proceedings is available at http://pcl.upjs.sk/workshopcdand https://sites.google.com/site/kogneuro/. We hope that this collection of lectures and assignments will find its excited readers and that it will provide an introduction that will be as enjoyable as the workshops were for the experts and the participants. And, we will be looking forward to meet some of the readers at future editions of the workshop.

The proposed text focuses on the history of studying biology, medicine, and pharmacy as scientific disciplines from prehistoric times through antiquity, the Middle Ages, and the modern era. The text chronologically organizes the most significant figures in the history of biological scientific disciplines, outlines key characteristics of major historical discoveries, and reevaluates their significance from the perspective of 21st-century science.
The educational text is chronologically divided into the most significant periods of civilization development. The last two completed centuries—the 19th and 20th—are subdivided into major life science fields due to the unprecedented growth of biological disciplines and the resulting volume of acquired information.
Since it can sometimes be challenging in science to define what constitutes the past versus the present of a particular discipline, we have excluded significant biological discoveries from the early 21st century, which are typically regarded as the “present” of biology.
The structure of the animal body is extremely varied. Each species has its distinctive morphological features, which bears as a testimony to long-term development and belonging to the developmental lineage. At the same time, the body has been tested for a long time by natural conditions, resulting in unique adaptations to the environment and life strategy. Despite this admirable variety - which includes both recent and fossil animals and which we have far from mapped – a comparison of body parts brings knowledge we can generalize: the main building principles, and boundaries within which phenotypic diversity is realized.
Comparative animal morphology today uses the latest methodological material and knowledge from other disciplines, from genetics, molecular biology and experimental embryology, through progressive imaging methods (e.g. electron microscopy, computer micro-tomography) and the possibilities of subsequent software processing of image material (measurement, staining, etc.) to the view of physics, chemistry, statics and geometry on the structures (to nanostructures) of the living body. Detailed knowledge of historical and contemporary conditions on Earth is an important interpretative context in the study of animal morphology. Surprisingly, the knowledge accumulated after centuries of research is now rapidly supplemented by new knowledge, and often the traditional knowledge is subsequently reinterpreted. Finally, and no less important, in studying animal (and human) morphology, we learn surprising knowledge about ourselves.
The author of the presented textbook had the ambition in a simplified form to introduce the reader, especially the student of biological studies, into a dynamic and fascinating scientific discipline, as the current comparative animal morphology is.
The proceedings contain abstracts of contributions from participants of the UNIFOS 2014 conference, University Information Systems in Košice, which took place from October 27 to 29, 2014.

This monograph is devoted to the discussion of effective field theory based on the differential operator method, originally introduced by Honmura and Kaneyoshi in 1979, which remains actively used for theoretical studies of localized spin models of magnetism—particularly variants of the Ising model. To date, this methodology has been applied by numerous authors to investigate a wide range of systems, including crystalline systems, diluted magnetic systems, systems with random exchange interactions, amorphous magnetic materials, systems under random magnetic and crystalline fields, thin magnetic layers, magnetic systems with free surfaces, binary and ternary magnetic alloys, among others.
During my scientific career, I have collaborated with several leading experts in this field—including Prof. Kaneyoshi, with whom I completed two long-term research stays—to advance the development of the differential operator method (and consequently effective field theory). Within this research area, I have published over 40 scientific papers in prominent international physics journals. These works include both methodological advancements and significant applications that predict intriguing physical phenomena, such as multicompensation phenomena in ferrimagnets.
These university textbooks are intended for first-year master's degree students at the Faculty of Natural Sciences of UPJŠ in Košice. The scope and content of the works included in these scripts are primarily based on time and spatial constraints, taking into account the material demands of the tasks.
The aim of these scripts is to teach students basic microbiological techniques and to show them the importance of microorganisms in everyday life and their crucial role in nature. The exercises are designed to enhance students' technical skills and teach them to work according to safety principles.
The text is divided into 13 parts. Each part begins with an introduction to the theory related to the practice topic. The appendix includes a proposal for the preparation of protocols for individual exercises.
The conference proceedings of Porous Materials for Environmental Applications 2026 represent a collection of scientific and professional contributions presented at the international scientific conference held on 15–19 March 2026 in Białka Tatrzańska (Poland). The conference focused on current trends in the research of porous materials and their applications in environmental, catalytic, energy-related, and biomedical fields. The event provided an interdisciplinary platform for the exchange of the latest scientific knowledge in the design, synthesis, characterization, and practical utilization of porous materials.
Particular attention was devoted to their application in adsorption and separation processes, heterogeneous catalysis, photocatalysis, energy storage and conversion, as well as in biological and medical applications. The published abstracts reflect current challenges related to sustainable development, green technologies, and advanced materials solutions. The proceedings offer a comprehensive overview of the current state of porous materials research at the international level and document the dynamic development of this field with significant overlap into environmental chemistry, materials science, and chemical engineering.
This textbook is primarily intended for first-year master's degree students at Pavol Jozef Šafárik University in Košice, especially those in the nuclear physics, subnuclear physics, and theoretical physics programs. For many years, these lectures were taught by one of the authors at this university, and naturally, over time, there arose an effort to provide these lectures to students in printed form.
In this textbook, we will focus mainly on classical field theory, its quantization based on the operator approach, and the introduction of interactions. Descriptions based on functional integration, Feynman diagram techniques, and more advanced parts will be covered in a subsequent volume of the textbook. In this context, we want to emphasize that in many modern quantum field theory textbooks, the operator approach is used to a lesser extent and is replaced by the approach using (functional) path integrals.
This is probably due to time considerations, as the functional approach leads much faster to practical calculations. On the other hand, we believe that the operator approach is better from a pedagogical point of view. It is much closer to the traditional quantum mechanics course, which is often based on the Schrödinger or Heisenberg formalism. Therefore, students can much more easily follow the flow of ideas that led to the construction of quantum field theory and its fundamental concepts.
The textbook is designed to prepare students who will engage in the experimental study of the properties of condensed matter. It demonstrates that a contemporary experimental physicist must not only possess sufficiently detailed knowledge of the physical processes occurring within the object under study but also understand the methods for creating the experimental conditions in which the experiment is conducted. Active knowledge of the functioning of the entire experimental setup can be of fundamental importance in the implementation or potential modification of the measurement methodology used.
The presented university textbook is intended for all students engaged in the field of condensed matter physics who, while working on their final theses, come into contact with the experimental device known as the Physical Properties Measurement System (PPMS). The main purpose of this textbook is to facilitate, in a certain way, the students' work with the complex manuals provided with this experimental device. At the same time, through this textbook and its clear instructions, students acquire the necessary experimental skills essential in the field of condensed matter physics.
Organic chemistry plays a key role in our lives, from the pharmaceutical industry to the production of plastics and food additives. Additionally, it is essential in biochemistry, as it deals with the basic building blocks of living organisms, such as carbohydrates, lipids, proteins, and nucleic acids. One of the best ways to teach organic chemistry and increase students' interest in the subject is through conducting school experiments. This study material presents a collection of visually striking practical experiments in organic chemistry that will help students better understand the chemical processes and techniques used in the field. This electronic study material is supplemented with visual material, allowing students to verify the results of experiments and better understand the individual procedures. At the end of each section, there are questions to help assess the acquired knowledge and encourage deeper understanding of the experiments conducted.
The publication is intended for researchers in didactics and teachers of mathematics and computer science. Our aim is to provide readers with a basic orientation in the issue of inquiry-based teaching, to explain and demonstrate several levels of student inquiry through examples, and to offer a classification of inquiry skills.
The core part of the publication consists of methodologies for inquiry-based teaching of specific topics from school mathematics and computer science. We present ideas for implementing inquiry activities, active work with information in solving various types of problems, and the application of modern digital technologies in exploring and discovering patterns.
The publication includes seven methodologies for teaching mathematics and eight methodologies for teaching computer science in the 1st and 2nd years of secondary school.
In these university-level textbooks, we present the fundamental concepts of networks and graph theory. We explore breadth-first and depth-first graph searching. We present static and dynamic network models. We describe the issue of detecting overlapping and non-overlapping communities in directed and undirected networks. Various approaches to anomaly detection in networks also form an important part of this textbook. The final chapter is dedicated to spectral clustering, which plays a significant role in data mining in network graphs for various application domains.
These textbooks are suitable for first and second-year university students in computer science programs. The study materials are also suitable for students in non-computer science fields, with the aim of improving their knowledge and practical experience in computer science-related areas, and provide an opportunity for students to find employment in IT companies to solve practical tasks.
For computer scientists, the constant challenge is to seek efficient algorithms and various technical and implementation possibilities to improve the computational complexity of currently known algorithms. Partial solutions are offered by approaches such as grid-based methods and parallelization of computation. Quantum computers represent a significant but still unfulfilled promise. From a theoretical perspective, probabilistic and approximation approaches provide very effective solutions, and these are the methods we aim to explore in detail.
These electronic university textbooks serve as supplementary materials for the course Approximation and Probabilistic Algorithms. They were developed from the authors' materials and contributions by Prof. RNDr. Viliam Geffert, DrSc., whom the authors thank for providing the manuscript. Acknowledgments also extend to RNDr. Ján Katrenič, PhD., who prepared the first set of exercises for the course, and Žaneta Semanišinová, who reviewed large portions of the text and contributed suggestions for its improvement.
Učebný text je primárne určený pre študentov jednoodborového štúdia biológie a všeobecnej ekológie, ako aj odborom učiteľského štúdia v rôznych kombináciách s biológiou. Venuje sa v nich opisu jednotlivých skupín živočíchov, ich morfológiu a anatómiu ilustruje na obrazových materiáloch. K jednotlivým morfologickým a anatomickým štruktúram sa v texte nevyjadrujeme podrobnejšie, nakoľko text nadväzuje na predmet Porovnávacia morfológia živočíchov, kde na úrovni organológie boli tieto najvýznamnejšie štruktúry v rámci prednášok a cvičení detailne vysvetlené a opísané. Rozsah učebného textu nie je veľký, podávame v ňom základné minimum poznatkov, čo je podmienené jednak rozsahom predmetu, ktorý je len jednosemestrový, jednak tým, že ďalšie, špecializované predmety rozširujú spektrum poznatkov napr. na úrovni entomológie, hydrobiológie alebo pôdnej biológie. V zavere niektorých kapitol formulujeme niekoľko cvičných otázok, ktoré si študenti môžu na základe predchádzajúceho textu zodpovedať, s podobnými otázkami sa totiž môžu stretnúť na skúške alebo na štátniciach.
