Scientific Computing with Open SageMath not only for Physics Education

Nowadays interactive digital scientific environments have become an integral part of scientific computing in solving various scientific tasks in research, but also STEM education. We introduce SageMath or shortly Sage -- a free open Python-based alternative to the well-known commercial software -- in the frame of our course Methods of Physical Problems Solving for future scientists and science teachers. Particularly, in the 1st illustrative example from the Physics Olympiad, we present Sage as a scientific open data source, symbolic, numerical, and visualization tool. The 2nd example from the Young Physicists' Tournament shows Sage as a multimedia, modeling, and programming tool. By employing SageMath as an open digital environment for scientific computing in the education of all STEM disciplines, teachers and students are empowered not only with a universal educational tool, but a real research tool, enabling them to engage in interactive visualization, modeling, programming, and solving of authentic, complex interdisciplinary problems, thus naturally enhancing their motivation to pursue science in alignment with the core mission of STEM education.Comment: 9 pages, 3 figures, 1 table, conference DIDSCI202

Blended learning: A data-literate science teacher is a better teacher

The COVID-19 pandemic has underscored the importance of blended learning in contemporary physics and, more generally, STEM education. In this contribution, we summarize current pedagogical models of blended learning, such as rotational and flexible non-rotational models, and customizable configurations of physical and virtual learning spaces. With the inevitable integration of digital technology as one of the pillars of blended learning, teachers find themselves in an unprecedented position to not only obtain data more frequently but also analyze it and adjust instruction accordingly. Consequently, we discuss a crucial element of blended learning effectiveness: data management and usage. In this context, data literacy for teaching emerges as an essential skill for effective blended learning, encompassing the ability to transform various data types into actionable instructional knowledge and practices. In other words, current research in physics education shows that a data-literate science teacher is a more prosperous and effective teacher.Comment: 9 pages, 4 figures, preprint conference DIDFYZ202

Social Reader Perusall -- a Highly Effective Tool and Source of Formative Assessment Data

The contribution provides a detailed exploration of the online platform Perusall as an advanced social annotation technology in teaching and learning STEM disciplines. This exploration is based on the authors' insights and experiences from three years of implementing Perusall at P.J. \v{S}af\'arik University in Ko\v{s}ice, Slovakia. While the concept of social annotation technology and its educational applications are not novel, Perusall's advanced features, including AI and data science reports, enable its use in both synchronous and asynchronous blended and flipped learning environments. In this context, Perusall serves as a digital tool for collecting formative data, monitoring student progress, and identifying areas of difficulty. This assessment data can be effectively utilized in preparing and personalizing subsequent face-to-face group interactions, thereby enhancing and improving the learning experience. From a pedagogical viewpoint, Perusall's role was particularly significant during the Covid-19 pandemic, enabling effective, continuous, and engaging learning amidst social distancing and physical restrictions. Today, Perusall has become a key tool in blended learning, facilitating higher-order cognitive processes during the educational process and, with its multifaceted applications, serves as a modern catalyst in redefining educational experiences and outcomes.Comment: 8 pages, 4 Figures, conference DIDSCI2022 preprin

Innovative approaches to high school physics competitions: Harnessing the power of AI and open science

High school physics competitions serve as a platform for talented students to showcase their skills, engage in challenging problems, and foster a passion for science. This paper explores innovative approaches to enhance these competitions by harnessing the power of open science and artificial intelligence (AI) tools. Particularly we delve into the capabilities of state-of-the-art AI chatbots, i.e. ChatGPT, Bard, Claude, related to problem solving in physics. Together with open science tools like SageMath and Jupyter AI, they have the potential to serve as intelligent, powerful co-pilots, tutors, and assistants in understanding and applying physics, as well as knowledge from connected STEM fields. Furthermore, these innovative approaches can revolutionize high school physics competitions, providing students and their tutors with powerful resources to excel in their scientific pursuits.Comment: 10 pages, 4 figures, preprint DIDFYZ2023 conferenc

COMFORT AND SAFETY OF WORK CLOTHES IN CONSTRUCTION

katedra: KHT; rozsah: 59sIn the present work is processed at the same time used work clothes in the Regional road administration of the Liberec region and proposals for their improvement. Using questionnaires were found to have a current impact on the workers. Based on this evaluation, it was proposed a new solution of workwear, while maintaining current costs. The new solution will be presented to company management of Regional road administration of the Liberec region.V předložené práci je zpracována analýza současně používaných pracovních oděvů v Krajské správě silnic Libereckého kraje a návrh na jejich zlepšení. Prostřednictvím přímého dotazování pracovníků pomocí jednoduchých dotazníků bylo zjištěno, jak zaměstnanci současné oděvy vnímají. Na základě vyhodnocení výzkumu bylo navrženo nové řešení pracovních oděvů, při zachování současných nákladů. Nové řešení bude předloženo managementu společnosti

Design and implementation of a native mobile application for non-bank business representatives

Tato práce se zabývá návrhem a implementací mobilní aplikace pro nebankovní společnost. Aplikace je určena obchodním zástupcům, kteří navštěvují klienty a sepisují s nimi smlouvy, nabízejí další produkty a vybírají splátky. Obchodní zástupce potřebuje znát informace o klientovi, takže je potřebuje mít stále při sobě, tedy tato aplikace mu k tomu dopomáhá. Nabízí základní statistiky, seznamy klientů a formuláře k vyplnění. Také mu poskytuje potřebné pomůcky k jednodušší práci se zákazníkem.This thesis deals with design and implementation of a mobile application for the non-banking company. The app is intended for business representatives who visit clients and write contracts, offer additional products and choose installments.

It also provides him with the necessary tools to make it easier to work with the customer

Myosin II synergizes with F-actin to promote DNGR-1-dependent cross-presentation of dead cell-associated antigens

Conventional type 1 DCs (cDC1s) excel at cross-presentation of dead cell-associated antigens partly because they express DNGR-1, a receptor that recognizes exposed actin filaments on dead cells. In vitro polymerized F-actin can be used as a synthetic ligand for DNGR-1. However, cellular F-actin is decorated with actin-binding proteins, which could affect DNGR-1 recognition. Here, we demonstrate that myosin II, an F-actin-associated motor protein, greatly potentiates the binding of DNGR-1 to F-actin. Latex beads coated with F-actin and myosin II are taken up by DNGR-1+ cDC1s, and antigen associated with those beads is efficiently cross-presented to CD8+ T cells. Myosin II-deficient necrotic cells are impaired in their ability to stimulate DNGR-1 or to serve as substrates for cDC1 cross-presentation to CD8+ T cells. These results provide insights into the nature of the DNGR-1 ligand and have implications for understanding immune responses to cell-associated antigens and for vaccine design
